First, emulsion resin Emulsion resin refers to resin particles suspended in water, which is widely used. There are many different emulsion resins on the market, such as polyurethane, acrylic, etc. They have the characteristics of strong adhesion, fast drying, etc., suitable for various printing and coating fields. Second, solvent-based resin Solvent-based resins should pay attention to environmental protection and safety in the production, and need to be properly handled. The resin is dissolved in an organic solvent and coated on the surface of the paper. They have excellent surface smoothness and water resistance, but are prone to problems when overprinted with other coatings or inks. Three, waterborne polyurethane Waterborne polyurethane resins are used more in the coating industry and have the characteristics of organic solvent-based resins, but because of the use of water instead of solvents, they are more superior in environmental protection and safety. Waterborne polyurethane resin is suitable for different printing and coating fields, with excellent wear resistance and scratch resistance. Four, water-based acrylic resin Water-based acrylic resin is often used in the printing industry, with environmental protection, not easy to fire and other advantages. However, compared with the solvent-based resin, the surface gloss is not as good as the solvent-based resin, and the temperature, particles and viscosity of the paper surface coating are also required. Five, UV light curing resin UV curing resins are characterized by rapid curing after exposure to UV light. They have the advantages of fast drying and high hardness, the disadvantage is that the use of the process needs to pay attention to the light time, intensity and other parameters. At present, it is widely used in packaging, printing, decoration and other fields. In summary, the types of resins used in the surface coating of paper include emulsion, solvent-based, water-based polyurethane, water-based acrylic resin and UV light curing resin, which have their own characteristics and application fields. In the process of production and use, attention should be paid to environmental protection and safety, and suitable resins should be selected for different printing and coating fields.

First, what is the adhesion of resin Resin adhesion refers to the ability of the resin coating to adhere to the substrate. Insufficient adhesion of the resin on the surface can cause it to fall off or foam, and affect the service life and performance of the product. Second, how to effectively improve the adhesion of resin 1. Surface treatment Surface treatment is an effective method to improve the adhesion of resin. By obtaining surface roughness and increasing surface energy, the ability of the resin to adhere to the surface of the substrate can be improved. Surface treatment can be achieved by sandblasting, chemical cleaning and other methods. 2. Temperature control Temperature is also an important factor affecting the adhesion of resin.  The high temperature will cause the resin to cure quickly and reduce the adhesion between the resin and the substrate.  If the temperature is too low, it will lead to poor resin fluidity and reduce the diffusivity of the resin.  Therefore, during the production process, attention should be paid to controlling the temperature of the resin and the substrate, and the resin coating should be carried out at the correct temperature. 3. Selection of resin adhesive The choice of resin binder is also an important factor to improve the adhesion of resin. Different adhesives have different effects on different substrates, which should be selected according to the substrate type and the resin coated object. Commonly used adhesives are acrylic resin, epoxy resin and polyurethane resin. 4. Improve the accuracy and uniformity of resin coating The precision and uniformity of the resin coating are also important. If the thickness of the resin coating is not uniform, it will lead to reduced adhesion, and the uniformity of the coating should be improved by adjusting the coating speed and coating method during the production process. 5. Ensure drying time and curing quality The drying time and curing quality of the resin coating are also important. If the resin coating is moved or subjected to pressure before curing, the adhesion of the resin will be affected. In the production process, the curing time and curing quality of the resin should be guaranteed to improve the adhesion of the resin Sinograce Chemical production tackifier resin emulsion, welcome to consult.

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.
