n-Butyl acrylate is an important organic chemical raw material, which is widely used in polymer, coating, adhesive, fiber and other fields. This article will detail the properties and uses of n-butyl acrylate.

1. the nature of n-butyl acrylate

n-butyl acrylate is a colorless and transparent liquid with a strong pungent odor. Its molecular formula is C7H12O2 and its molecular weight is 128.17. n-Butyl acrylate has a strong volatility and flammability, in case of open flame, high heat or oxidant contact, there is a risk of combustion and explosion.

n-butyl acrylate is chemically active and prone to polymerization. Under the action of light, heat, peroxide and other initiators, n-butyl acrylate can be rapidly polymerized to form poly-n-butyl acrylate. In addition, n-butyl acrylate can also be copolymerized with other monomers to produce a variety of polymers with different properties.

2. of n-Butyl Acrylate Use

1. High molecular polymer

n-Butyl acrylate can be used as a monomer to generate high molecular polymers such as poly-n-butyl acrylate through polymerization reaction. These polymers have good weather resistance, water resistance, oil resistance, impact resistance and other properties, widely used in coatings, adhesives, plastics and other fields.

2. Coating

n-Butyl acrylate can be used as one of the main components of coatings to prepare various high-performance coatings. For example, copolymerization of n-butyl acrylate with styrene, acrylic acid and other monomers can prepare exterior wall coatings with good weather resistance, water resistance and color retention; copolymerization with vinyl acetate and other monomers can prepare interior wall coatings, wood coatings and the like.

3. Adhesive

n-Butyl acrylate can be used as one of the main components of the adhesive to prepare various adhesives. For example, n-butyl acrylate can be copolymerized with vinyl acetate, acrylic acid and other monomers to prepare adhesives with good adhesive properties and water resistance, which are widely used in wood processing, paper processing, textiles and other fields.

4. Fiber

n-Butyl acrylate can be used as a fiber modifier to improve the performance of the fiber. For example, copolymerization of n-butyl acrylate with acrylonitrile can prepare acrylic fibers with good elasticity and wear resistance, and copolymerization with methyl methacrylate can prepare organic glass fibers with high transparency and high impact resistance.

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