acrylic acid and its series products, mainly its esters, have been rapidly developed in recent years. Such as ethylene, propylene, vinyl chloride, acrylonitrile, etc., developed into an important polymer chemical industry raw materials. Acrylic acid and its esters as monomers of polymer compounds, the world's total output has exceeded millions of tons, and the production of polymers and copolymers made from it (mainly emulsion resins) is nearly 5 million tons. These resins are used in many sectors such as coatings, plastics, textiles, leather, paper, building materials, and packaging. Acrylic acid and its esters can be used for organic synthesis and polymer synthesis, and most of them are used for the latter, and more are copolymerized with other monomers, such as vinyl acetate, styrene, methyl methacrylate, etc., to produce synthetic resins with various properties, functional polymer materials and various auxiliaries. Main application areas:
(1) Warp sizing material made of acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate and other raw materials, the warp sizing material is more than polyvinyl alcohol sizing capacity, saving starch.
(2) Adhesive with acrylic acid, methyl acrylate, ethyl acrylate, acrylic acid - 2-ethylhexyl ester and other copolymer latex, can be used as electrostatic flocking, flocking adhesive, its firm and feel good.
(3) Water thickener with acrylic acid and ethyl acrylate copolymer made of high molecular weight powder. Can be used as a thickening agent, used in oil fields, each ton of product can increase 500t crude oil, the old well oil recovery effect is better.
(4) Coated paper coating agent with acrylic acid, butyl acrylate, acrylic acid - 2-ethylhexyl ester, styrene and other four-element copolymer latex for coated paper coating, color preservation does not yellowing, printing performance is good, non-stick roller, better than styrene butadiene latex can save dry cool.
(5) Polyacrylates The use of acrylic acid can produce a variety of polyacrylate products (such as ammonium salt, sodium salt, potassium salt, aluminum salt, nickel salt, etc.). Used as agglutinant, water treatment agent, dispersant, thickener, food preservative acid and alkali desiccant, softener and other polymer additives.
