What are the applications of acrylate?

Acrylic esters have a wide range of applications due to their different excellent characteristics and greater market demand. With the needs of radiation curing, textile industry, adhesives, coatings and other industrial fields and environmental protection in various regions of the world, the development of various functional acrylates continues to extend.

(1) Textile
Acrylate emulsion polymers have various properties and uses due to differences in the ratio of raw materials and processing methods in the preparation process. They are widely used in the textile industry and have a very special status.
Acrylic emulsions are mainly used as thickeners and fabric adhesives in pigment printing. The most domestic application is low-temperature curing fabric adhesive, the main component of which is a copolymer of acrylate and vinyl monomer. This fabric adhesive containing self-crosslinking groups has strong adhesion to coatings and fibers, and the product has good fastness. The adhesive has good fluidity and wide variability. In the production of sizing agents, sizing sizing agents for textile warp yarns commonly used at home and abroad mainly include polyacrylates and their copolymers and polyvinyl alcohols. It can be seen from the comparison of performance that synthetic polyvinyl alcohol is the preferred slurry, but this slurry is easy to cause environmental pollution and has the disadvantages of sizing and difficult to separate and twist. Some countries in Western Europe have strictly banned the production and sales of polyvinyl alcohol sizing agents. The China Textile Industry Association has also proposed to use such sizing agents less frequently. Therefore, there is an urgent need to find environmentally friendly sizing agents that can replace polyvinyl alcohol sizing agents. Class is the most suitable substitute, it can be well matched with natural starch to meet the sizing requirements of most products. With the rapid economic development, the demand for acrylates at home and abroad is increasing year by year, and its application in the textile industry will be in a strong state.

(2) Adhesive
Polyacrylate adhesives are one of the most widely used fields of acrylates. They have the advantages of wide bonding range, low toxicity, weather resistance, simple formula, and low price, but they have poor temperature resistance and thermoplasticity. Acrylic adhesives can be divided into anaerobic adhesives, pressure-sensitive adhesives, dry adhesives and two-component instant adhesives according to application methods.

(3) Paint
Acrylic coating is a new type of cross-linkable thermosetting material with comprehensive properties, various types and rich forms. It has the characteristics of green pollution-free, mechanical properties, chemical resistance and gloss and color retention. In recent years, the consumption of acrylic coatings has far exceeded that of alkyd coatings. There are three uses for acrylic coatings: architectural coatings, original equipment coatings (OEM) and special coatings.

(4) Other applications
Acid esters are used as paper enhancers and paper adhesives in the paper industry, which can improve paper strength, cohesion and mechanical stability. Acrylic acid and its ester polymers are mainly used as surfactants, leather finishing agents, fillers, antifouling agents, etc. in the leather production process to improve leather quality. Acrylate polymers are essential oilfield chemicals in the process of oil and natural gas extraction, gathering and transportation, and water quality treatment. They are mainly used as pour point depressants, crude oil demulsifiers, scale inhibitors, water quality stabilizers, etc.
