Adhesive: In the adhesive industry, butyl acrylate is an important monomer used to produce various types of adhesives, including water-based and solvent based adhesives. It helps to improve the adhesive strength and weather resistance of the adhesive.

 

Textile coating: The application of butyl acrylate in textile coatings can endow fabrics with waterproof, oil resistant, and stain resistant properties, while maintaining the breathability and comfort of the fabric.

 

Plastic products: Butyl acrylate can also be used to produce various plastic products, such as plastic films, pipes, and containers. It helps to improve the mechanical strength and environmental resistance of plastics.

 

Other applications: In addition to the above-mentioned fields, butyl acrylate is also used to manufacture lubricant additives, defoamers, emulsifiers, etc., demonstrating its widespread application in the chemical industry.

 

Basic characteristics of butyl acrylate

 

Chemical structure and physical properties

 

Chemical structure: Butyl acrylate is composed of an acrylic acid group (CH2=CHCOO -) and a butyl ester group (CH3CH2CH2CH2O -).

 

Appearance: It is a colorless transparent liquid with a characteristic irritating odor.

 

Boiling point: Its boiling point range is 145-149 ° C, depending on pressure conditions.

Melting point: The melting point of butyl acrylate is relatively low, about -64.6 ° C.

 

Density: At 25 ° C, its density is approximately 0.894 g/mL.

 

Solubility: Butyl acrylate has a low solubility in water, with a solubility of approximately 0.14g/100mL at 20 ° C, but can be mixed with organic solvents such as ethanol and ether.

 

Flash point: Its closed cup flash point is within the range of 35-40 ° C, indicating that it is flammable near room temperature.

 

Security and stability

 

Stability: Under normal conditions, butyl acrylate is stable, but polymerization reactions may occur when exposed to heat, light, or air. Five

 

Prohibited substances: Avoid contact with strong oxidants, strong bases, and strong acids, as these substances may cause dangerous chemical reactions.

 

Polymerization hazard: Butyl acrylate may release heat during polymerization, and if not controlled, it may cause temperature rise and pressure accumulation, leading to explosions.

 

Storage method: It should be stored in a cool and ventilated warehouse, away from flames and heat sources, and the temperature should not exceed 37 ° C. The packaging should be sealed, not in contact with air, and stored separately from oxidants, acids, and alkalis.

 

Safety measures: The operating area should maintain good ventilation, and operators should wear appropriate protective equipment, such as protective clothing and gloves. When dealing with leaks, explosion-proof lighting and ventilation facilities should be used, and the use of mechanical equipment and tools that are prone to sparks should be prohibited

 

Application in the manufacturing of coatings and adhesives

 

As a solvent and diluent

 

Butyl acrylate is commonly used as a solvent and diluent in coatings and adhesives due to its excellent solubility. It can effectively dissolve a variety of resins and polymers, help to form a uniform solution or lotion, thus improving the fluidity and coating properties of coatings. In addition, compared to other solvents, the low volatility of butyl acrylate helps to reduce the emissions of volatile organic compounds (VOCs) from coatings during use, which is beneficial for the environment and human health.

 

Improve the durability and gloss of coatings

 

Butyl acrylate also helps to improve the durability and gloss of coatings in coating formulations. Its weather resistance and UV resistance enable the coating to maintain long-term stability and color brightness when used outdoors. In addition, the addition of butyl acrylate can improve the flexibility and adhesion of the coating, enabling it to better resist environmental factors such as temperature changes, humidity, and mechanical stress, thereby extending the service life of the coating.

 

 

Use in textile and leather processing

 

Coating and Printing of Textiles

 

Coating: Butyl acrylate, as the main component of the coating agent, can provide excellent adhesion and weather resistance, making the coating have good water resistance, wear resistance, acid and alkali resistance, and temperature resistance. Coated textiles have characteristics such as wind resistance, enhanced hand feel, and drapability, and are widely used in polyester cotton windbreakers, nylon ski shirt fabrics, and so on.

 

Printing: In textile printing, butyl acrylate can be used as an adhesive to enhance the firmness of printed patterns and the brightness of colors. It has good transparency and compatibility, which is conducive to the production of colored coating products. At the same time, it has good washing resistance and strong adhesion.

 

Softening and finishing of leather

 

Softening: The application of butyl acrylate in leather processing includes serving as a softener, which can give leather a soft feel and good cold resistance, while improving its heat resistance. Through specific formula and technical treatment, butyl acrylate lotion leather finishing agent can provide excellent embossing and shearing resistance, so that the leather has good release and pattern fullness under high temperature.

 

Finishing: In the leather finishing process, butyl acrylate lotion can be used as an effective treatment agent. It can not only improve the beauty and touch of leather, but also provide protection, enhance the durability and resistance to environmental impact of leather.
