Hydroxyethyl acrylate (HEA) is an important organic chemical raw material, which is widely used in coatings, inks, adhesives, plastics, fibers and other fields. This article will detail the properties and uses of hydroxyethyl acrylate.

1. the properties of hydroxyethyl acrylate

1. physical properties

hydroxyethyl acrylate is a colorless transparent liquid, with ester specific odor. It has a high boiling point of 95~97 ℃, a density of about 1.109g/cm³, a refractive index of 1.4432, and a flash point of 107 ℃. In addition, hydroxyethyl acrylate and water, alcohol, ether and other solvents can be miscible.

2. chemical properties

hydroxyethyl acrylate molecules contain carbon-carbon double bonds and hydroxyl groups, so it has good reactivity. It can occur addition, esterification, polymerization and other reactions to generate a variety of derivatives. In addition, hydroxyethyl acrylate also has good water resistance, weather resistance, chemical resistance and so on.

2. the use of hydroxyethyl acrylate

1.

of the coating industry hydroxyethyl acrylate can be used as a monomer coating resin, through the polymerization reaction to generate hydroxyethyl acrylate resin, with excellent weather resistance, water resistance, light and color retention characteristics, widely used in construction, automotive, furniture and other fields.

2. Ink industry

Hydroxyethyl acrylate can be used to prepare ink to improve the drying and adhesion of ink. It can also be copolymerized with other monomers to prepare ink products with different properties.

3. Adhesive Industrial

Hydroxyethyl acrylate can be used as the raw material of the adhesive to improve the bonding strength and water resistance of the adhesive. It is an adhesive prepared by copolymerization with other monomers, which is widely used in wood processing, construction, automobile and other fields.

4. plastic industry

hydroxyethyl acrylate can be used as a plastic modifier to improve the toughness, impact resistance and processing properties of plastics. It can also be copolymerized with other monomers to prepare plastic products with different properties.

In conclusion, as an important organic chemical raw material, hydroxyethyl acrylate has broad application prospects in the field of chemical production raw materials.
