The role of wax emulsion in various coatings, in the coating formulation, polyethylene wax emulsion can effectively improve the wear resistance of the paint film, the paint film is very smooth, effectively reduce the friction coefficient of the coating, play a non-adhesive role, but also improve the service life of the product. 1.Synthetic wax emulsion can improve the toughness of the coating: when using plastic as the base material, the requirements for the coating are different. Commonly used low molecular weight polyethylene wax emulsion. When applied to acrylic or polyethylene glycol copolymers, the crosslinking and affinity of thermosetting coatings will be greatly improved. 2.Water-based wax emulsion can improve the wear resistance, scratch resistance and adhesion resistance of the coating. It can be used as primer and topcoat for transparent high gloss system without affecting transparent gloss and recoating performance. The abrasion resistance, scratch resistance, hardening resistance, smoothness and adhesion resistance of the coating are significantly improved. 3.Synthetic wax emulsions are used in different areas of the coating of different products, for example, wax emulsions can improve the anti-sagging property of architectural coatings, polyethylene wax emulsions, which have good stability due to the coating systems used to manufacture anti-settling agents, in many solvent-based resin systems. The addition can prevent silica gel from settling or oxidizing polyethylene wax to form a lump. In the painting/printing process of various coatings, it is often necessary to have a dry, full, anti-adhesion film, which does not affect the performance of the entire product. The main anti-adhesion effect is achieved by adding water-based wax emulsion to the coating formulation.

Before the textile coating, it is necessary to pretreat the textile surface to ensure the adhesion and quality of the coating. Common surface treatment methods are: cleaning, degreasing, polishing and so on. Cleaning can be done with hot water or solvents, degreasing can be done with alkaline or acid degreasing agents, and polishing is done by mechanical removal of surface hair. The choice of coatings should be selected according to the material, use and appearance requirements of textiles. Commonly used coatings are: polyurethane, acrylic, carbon fiber and so on. The coating method is selected according to the thickness and uniformity of the coating. The commonly used coating methods are: dipping, rolling coating, spraying, scraping coating and so on. Among them, the scraping coating method is more suitable for the coating with higher thickness requirements. Drying method is also one of the important factors affecting the quality of the coating. Commonly used drying methods are: natural drying, drying room, hot air drying and so on. Among them, hot air drying can quickly complete the drying process, but it will affect the shape and appearance of the textile, which needs attention. After the coating, it is necessary to cut, sew, iron and other post-processing to make the appearance and use of the textile to achieve the ideal state In short, the textile coating process needs to consider a number of factors, including surface treatment, paint selection, coating method, drying method and post-treatment.

There are several main reasons for water-based emulsion breaking: 1.Large temperature changes, water-based emulsion is easy to separate into water phase and oil phase at high temperature, and easy to crystallize at low temperature. 2.The selection of emulsifier is improper, and the type and dosage of emulsifier are different, which has a great impact on the stability of emulsification. The choice of emulsifier should be based on the nature of the emulsifying system. 3.Emulsion particles are too large, particle size and stability are important factors affecting emulsion demulsification, when the particle size is too large, easy to appear demulsification phenomenon. 4.Water-based emulsion preparation is improper, such as uneven mixing, emulsification time is too long. Second, measures to prevent water-based emulsion breaking In order to prevent water-based emulsion breaking, the following measures can be taken: 1.Select the right emulsifier, and select the right emulsifier according to the nature of the emulsifying system. 2.Control the particle size of water-based emulsion, the particle size is generally controlled between 0.1 and 1 micron, and the particle size is too large to directly affect the stability. 3.Avoid high and low temperature environments and store at room temperature. 4.In the preparation process, we should strictly follow the process requirements, such as selecting appropriate emulsifier, improving the particle distribution of emulsion, controlling the emulsion time, etc., which can improve the stability of emulsion. In short, the phenomenon of water-based emulsion breaking is a common problem in the process of emulsion storage and use, but as long as the reasonable formula and operation skills are mastered, the impact of emulsion breaking can be effectively prevented.

First, water-based lotion Aqueous emulsion is a colloidal dispersion system with water as the continuous phase and oil or other non-aqueous substances as the dispersing phase. It is a stable dispersion system formed by tiny oil droplets coated with surfactants. Water-based emulsion has many significant advantages, such as its low viscosity, easy to brush, easy to clean, non-toxic and harmless. Therefore, it has been widely used in various industrial fields, such as coatings, textiles, plastics and so on. Second, dispersion Dispersion is a colloidal dispersion system consisting of solid or liquid particles dispersed in liquid. Compared with water-based emulsions, the dispersion has a weak interaction force between particles, so it is easy to disperse and not easy to gather. Dispersions have a wide range of applications, such as pharmaceutical preparation of oral suspensions or sustained-release agents; In the preparation of pigments or automotive paints, dispersions can be used as thickeners and stabilizers. Third, the performance difference between water-based emulsion and dispersion 1.Stability The stability of water-based emulsions is higher than that of dispersions. Because the attraction between particles in water-based coatings is greater, it is easy to coagulate and precipitate. However, the particles in the dispersion have less interaction force and are easy to aggregate and precipitate. 2.Water resistance Water-based emulsion has better water resistance, and can form emulsion in water, without stratification; Dispersions generally do not have water resistance. 3.Transparency The transparency of dispersions is generally higher than that of water-based emulsions, which makes dispersions have a wide range of application prospects. However, due to the dispersion of oil droplets in the emulsion, water-based emulsions tend to have better covering power than dispersive emulsions. 4.Economy In the case of the same performance, the cost of the dispersion is lower than that of the water-based emulsion, because the preparation of the dispersion system does not require surfactants and other special additives. In short, water-based emulsions and dispersions have their special properties and advantages. According to the actual needs and application scenarios, it is particularly important to choose a suitable decentralized system.
