The formulation and production process of vae emulsion waterproofing materials involve a variety of ingredients and steps.
Formulation: The main component of VAE emulsion is vinyl acetate copolymer, which provides adhesiveness, stability and elasticity, as well as emulsifier, defoamer, stabilizer and auxiliary agent. These ingredients help to form a stable emulsion state, increase its adhesion and durability, and depending on the specific application needs, additives such as thickeners and preservatives may be added.
Production process: The production process includes raw material preparation, mixing, heating, emulsification, pH adjustment and adding additives. First of all, the ethylene acetate copolymer and other raw materials are added to the reaction kettle, adding an appropriate amount of water to stir and mix, and then heating to a certain temperature to start the polymerization reaction, adding emulsifier through stirring and high-speed shear to form a stable emulsion, adjust the pH value according to the need, and finally add additives, packaging and sealing.
In addition, there are other ingredients such as polyurethane emulsion, thickener, dispersant, etc., used to improve the bond strength, durability, softness, wrinkle resistance and so on. These ingredients are widely used in different fields such as building materials, textile printing and dyeing, paper industry, coatings industry and adhesives.
