Application range of wax emulsion

Wax emulsion is used in the leather industry

(1) Wax emulsion can be combined with fat additive

A small amount of emulsified wax is added to the fat agent to improve and increase the effect of fat agent. It is proved by experiments that the filling property of fat agent can be improved, the permeability of fat agent in skin fiber can be improved, the waterproof property of leather can be increased, and the leather can feel smooth, soft and plump.

(2) Wax emulsion is used as an additive for leather finishing

Adding emulsified wax to leather finishing agent can fill the coating, improve the feel of the coating, wear resistance, anti-sticking and increase the luster. In the early days, beeswax, palm wax, worm wax, ash wax, montane wax were mainly used as raw materials to prepare emulsifying wax. The production of these waxes is limited and the price is high. In recent years, paraffin wax has been used as the main raw material to prepare wax emulsion for leather. Using paraffin as the main raw material can greatly reduce the price of wax emulsion, and the use effect is not worse than natural wax, is the main auxiliary for coating leather, can give leather special brightness and wax. From the use can be divided into soft wax and hard wax, respectively used for leather bottom, middle and top coating; The emulsion can be divided into non-ionic, anionic and cationic wax emulsions according to its ionic properties, which can be used with different ionic finishes. Emulsion or solid emulsified wax can be prepared from the dosage form. The water solubility of all products is very good, the emulsion is stable, long-term storage without stratification, no floating wax. It can be applied to all kinds of leather coating, and the luster of the leather after coating is soft and natural, and the feel is full and moist, which can improve the friction resistance of the leather surface.

(3) Emulsified wax is used as leather brightener, matting agent and feel agent

People have two categories of requirements for the appearance of leather products, one is to increase the luster of leather, such as polishing leather, lacquer leather, polishing effect leather; The other is not glossy, so that the leather presents a sense of natural beauty. The former requires the use of brightener, the latter requires the use of extinction agent. When different wax emulsions are used for leather top coating, some can increase the luster or brightness of the leather, and some can produce a matting effect to show charm. The wax emulsion with bright effect has a small particle size requirement and a relatively simple composition. It forms a homogeneous and continuous wax film on the surface of the leather. The film is very smooth on the micro level and has a strong reflection effect on the light wave, thus having a luster sense. The wax emulsion with extinction effect has a large particle size and forms a heterogeneous and micro-uneven surface on the leather surface, which has a strong scattering effect on light waves, and the scattering effect is the fundamental reason for the extinction effect of the extinction agent.

Wax emulsions are used in construction

As a curing agent for reinforced concrete. During the curing process of concrete, if the water on the surface evaporates too quickly, a series of chemical reactions during the solidification process can not be completed, and the large compressive strength of the surface can not be reached. Therefore, water must be prevented from evaporating too quickly during the curing of concrete. To this end, the industry has developed a film curing agent with emulsified wax as the basic raw material, which avoids unnecessary surface water evaporation and promotes the hydration of cement.

Wax emulsions are used in agriculture

Horticultural practice has shown that plants absorb water mainly through their roots, and that the evaporation of water is lost from the surface of the leaves. The water consumption of the plant itself is not very large, such as coating the surface of its leaves with a waterproof evaporation spray film, which can greatly reduce the evaporation of water on the surface of the leaves. Plants need less than 50% of their water. Since the 1960s, the United States and other technologically advanced countries in the field of agriculture, in order to prevent fruit trees, shrubs, etc., in the winter dormance-down or transplanting and shipping on the way to die, the method of spraying emulsified wax was used, and into the 1970s, a large number of agricultural emulsified wax patents appeared. Emulsified wax liquid is mainly used for:

Seedling planting - Pine and eucalyptus seedlings are impregnated in emulsified wax before planting in the field. After treatment, the seedlings are significantly improved in their tolerance to the effects of transplantation or in their tolerance to adverse climatic conditions. Due to the decrease of water evaporation from the surface of the leaves, the survival rate was significantly improved.

Garden nursery planting - during pruning or transplantation, the survival rate can be significantly improved by emulsifying wax treatment. If a large number of shrubs need to be transplanted during the dry season, pre-spraying emulsified wax can ensure safe transplantation.

Drought resistance and preservation - saplings and shrubs that are sprayed with emulsified wax are well able to withstand severe dry conditions. After the flowers are picked, they can be soaked in water in advance, and then treated with emulsified wax, and the life of the flowers can be significantly extended.

Wax emulsions are used in the paper industry

In the process of paper selection, most of the paper is added with inner adhesive material, which can make the inherent absorbent membrane of the paper fiber have ideal water resistance. Traditional filling agents are commonly used in resins, such as emulsified wax, which can replace 20% to 40% of the traditional resin dosage. The addition of paraffin microemulsion can reduce the moisture absorption of paper and promote the uniform distribution of gum in the fiber structure of paper. Another benefit of adding emulsified wax is that it can counteract the effect of the resin binder when mixed with various pigments, so printability is improved, allowing printing efficiency to be increased. The paper that has been gummed in the beater can usually be further processed and refined by its surface compound or coating. New varieties of emulsified wax are being developed as a hydrophobic agent for the production of printed paper.

Wax emulsion is used for wood-based panels

Wood-based board including fiberboard and particleboard two kinds, these two boards are wood industry wood comprehensive utilization products, its composition in addition to wood fiber or wood chips, but also need to have a certain proportion of rubber, so that wood fiber or wood chips through hot pressing treatment gluing molding. A certain amount of emulsified wax is mixed with glue to make the wood resistant to water and improve the surface finish. Due to the small particle size of emulsified wax, in the wood-based board manufacturing process, through effective demulsification, the tiny wax particles can be precipitated from the water phase and uniformly adsorbed on the wood fiber, in developed countries, can not find a piece of particle board and fiberboard without emulsified wax production.

Wax emulsions are used for waterproofing wood

The emulsion wax is evenly coated on the surface of the wood that needs to be waterproof by soaking or spraying method. Because of the fine particle size of the emulsion wax, it can naturally penetrate into the interior of the wood, and the waterproof effect can be achieved by drying.

Wax emulsion is used in light industry and rubber industry

In the light industry, rubber industry, emulsified wax can be used as polish, paint and additives. In the pre-vulcanization process of manufacturing latex gloves, or in the gluing mixing tank, emulsifying wax can be added according to 1.5 to 2.5 amounts, which can improve the anti-viscosity of the mold and make it easy to release the glove. Emulsifying wax can improve the performance of latex in some emulsion formulations.

Wax emulsions are used in the ceramic industry

In the process of porcelain production, it is often necessary to add emulsified wax to make up for the poor plasticity of kaolin or improve the strength of the initial product. At the same time, emulsifying wax can also replace expensive vinyl acetate. In the process of ceramic production, emulsifying wax can improve both the strength and the lubricity of the initial porcelain products.

Wax emulsions are used in the petroleum industry

Drilling fluid plays an important role in oil drilling and production, its main functions are:

(1) Clean the bottom of the well and carry cuttings;

(2) Cooling and lubricating drill bit and drill string;

(3) Forming mud cake to protect well wall;

(4) Control and balance formation pressure.

Adding high quality emulsified wax to drilling fluid can significantly improve its inhibition and lubricity, prevent well collapse and increase drilling rate.

Wax emulsion is used in the textile industry

It is mainly used for yarn finishing and textile finishing agent. Yarn finishing is the application of emulsified wax to the finished line, which produces a high gloss, deeper and sharper color, and high elastic and tensile strength. It is mainly used as an important component of textile finishing agent, which aims to give these textiles excellent soft feel, good smoothness and gloss.

Wax emulsions are used as release agents

As a release agent, it is widely used in rubber or plastic products release, PU release, metal release and other fields.

Wax emulsion is used for waterborne coatings and waterborne inks

It can improve the anti-scratch properties, surface hydrophobic properties and anti-adhesion and anti-fouling properties of the coating film, so that the coating film is more smooth.
