Butyl acrylate is an important organic chemical raw material, which is widely used in polymer synthesis, coatings, adhesives, fibers and other fields. This article will detail the properties and uses of butyl acrylate.

1. properties of butyl acrylate

1. Physical properties

butyl acrylate is a colorless transparent liquid with a strong pungent odor. Its boiling point is 145 ℃, density is 0.897 g/cm ³, insoluble in water, miscible in ethanol, ether and other organic solvents.

2. Chemical properties

butyl acrylate has unsaturated double bonds and ester groups, so it has high chemical activity and is prone to polymerization, copolymerization, crosslinking and other reactions. In addition, butyl acrylate also has good weather resistance, water resistance, oil resistance, UV resistance and other properties.

2. the use of butyl acrylate

1. polymer synthesis

butyl acrylate can be used as monomer, copolymerized with other monomers to generate polymer. For example, with styrene, methyl methacrylate and other monomers, can be prepared with high transparency, high impact strength, high heat resistance of the polymer, widely used in the manufacture of plastic products, glass fiber reinforced materials and other fields.

2. Coating

Butyl acrylate can be used as the main film-forming material of coatings, and can be used in conjunction with pigments and fillers to produce coatings with high weather resistance, high decoration and high color retention, which are widely used in construction, automobiles, furniture and other fields.

3. Adhesive

butyl acrylate can be used as the main component of the adhesive and used in conjunction with other additives to produce adhesives with high viscosity, high water resistance and high heat resistance, which are widely used in wood processing, leather, textile and other fields.

4. Fiber

Butyl acrylate can be used as a modifier for fibers to improve their softness, elasticity and weatherability. For example, a modified fiber having flexibility and elasticity can be obtained by adding butyl acrylate to an acrylonitrile fiber.

In conclusion, butyl acrylate, as an important organic chemical raw material, is widely used in polymer synthesis, coatings, adhesives, fibers and other fields. With the continuous development of science and technology, the application field of butyl acrylate will continue to expand.
