Acrylic acid is an important raw material for organic synthesis and monomer of synthetic resin. Is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxylic group. Pure acrylic is a clear colorless liquid with a characteristic pungent odor. It is soluble in water, alcohol, ether and chloroform and is prepared from propylene obtained from oil refineries. Most of them are used to manufacture methyl acrylate, ethyl ester, butyl ester, hydroxyethyl ester and other acrylates. Acrylic acid and acrylate can be homopolymerized and copolymerized, their polymers are used in synthetic resin, synthetic fiber, super absorbent resin, building materials, coatings and other industrial sectors.

1, the important organic synthesis raw material and synthetic resin monomer, is the polymerization rate is very fast ethylene monomer. Most of them are used to manufacture methyl acrylate, ethyl ester, butyl ester, hydroxyethyl ester and other acrylates. Acrylic acid and acrylate can be homopolymerized and copolymerized, and can also be copolymerized with monomers such as acrylonitrile, styrene, butadiene, vinyl chloride and maleic anhydride. Its polymer is used in synthetic resin, adhesive, synthetic rubber, synthetic fiber, super absorbent resin, pharmaceutical, leather, textile, chemical fiber, building materials, water treatment, oil extraction, coating and other industrial sectors. Acrylic acid is one of the most important raw materials of water-soluble polymer.
2,Prepare high polymer by homopolymerization or copolymerization, used in coating, adhesive, solid resin, molding plastics, etc.
3, acrylic resin preparation, rubber synthesis, coating preparation, pharmaceutical industry;
4, warp sizing
The warp sizing material prepared from acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate and other raw materials has a higher capacity than that of polyvinyl alcohol and can save starch.
With acrylic acid, methyl acrylate, ethyl acrylate, acrylic acid -2- ethyl hexyl ester and other copolymer latex, can be electrostatic flocking, flocking adhesive, its firmness and feel good.
High molecular weight powders were prepared from acrylic acid and ethyl acrylate copolymer. It can be used as a thickening agent for oil fields, and can increase crude oil production by 500t per ton, which is good for oil recovery in old Wells.
(2) adhesive with acrylic acid, methyl acrylate, ethyl acrylate, acrylic acid -2- ethyl hexyl ester, etc.;
7, coated coated paper agent
Using acrylic acid, butyl acrylate, 2-ethyl-hexyl acrylate, styrene and other quaternary copolymer latex for coated paper, color retention and non-yellowing, good printing performance, non-stick roller, better than styrene butadiene latex can save dry cool;
Acrylic acid can be used to produce various polyacrylate salt products (such as ammonium salt, sodium salt, potassium salt, aluminum salt, nickel salt, etc.). Used as coagulant, water treatment agent, dispersant, thickener, food preservative acid-resistant desiccant, softener and other polymer additives.
