[Chemical Knowledge]：What are the role and uses of acrylic acid

Read： 1404 Time：29months ago Source：

acrylic acid is a colorless liquid. There's a pungent smell. It can be miscible with water, ethanol, and ether, and is easy to polymerize when exposed to light or heat. Generally, about 0.02% hydroquinone-methyl ether is often added as a polymerization inhibitor. Melting point 14 ℃; Boiling point 141.0 ℃; Flash point 155 °F(68 ℃, open cup);d164 1.0621;n20D 1.4224. Oral administration of LD50 rats: 2.59 g/kg.

Eight functions and uses

of acrylic acid 1. Preparation of polymers by homopolymerization or copolymerization, used in coatings, adhesives, solid resins, molding compounds, etc.

2. Used in resin manufacturing, synthetic rubber emulsion manufacturing and other fields

3. Used to manufacture various plastics, coatings, adhesives, elastomers, as well as floor polishes and paints.

4. The warp yarn sizing is made of acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate and other raw materials. The warp yarn sizing is better than polyvinyl alcohol sizing capacity and saves starch.

5. The adhesive uses acrylic acid, methyl acrylate, ethyl acrylate, acrylic acid -2-ethylhexyl ester and other copolymer latex, which can be used as electrostatic flocking and flocking adhesive with good firmness and hand feeling.

6. Water thickener is used to make high molecular weight powder from copolymer of acrylic acid and ethyl acrylate. It can be used as a thickener for oil fields. Each ton of products can increase the production of 500t crude oil, which has a good oil production effect on old wells.

7. Coated Paper Finishing Agent Using acrylic acid, butyl acrylate, acrylic acid -2-ethylhexyl ester, styrene and other quaternary copolymer latex as coated paper coating, color retention is not yellowed, printing performance is good, non-stick roller, better than styrene butadiene latex can save dry cool.

8. Polyacrylic acid salts Acrylic acid can be used to produce various polyacrylic acid salt products (such as ammonium salt, sodium salt, potassium salt, aluminum salt, nickel salt, etc.). Used as agglutination agent, water quality treatment agent, dispersant, thickener, food preservative acid and alkali resistant desiccant, softener and other polymer additives.;
