Acrylic resin is the general name for acrylic acid, methacrylic acid and their derivative polymers. There are many kinds of resins. According to the differences in structure and film-forming mechanism, it can be divided into thermoplastic acrylic resin and thermosetting acrylic resin.
Acrylic resin is the general name for acrylic acid, methacrylic acid and their derivative polymers. There are many kinds of resins. According to the differences in structure and film-forming mechanism, it can be divided into thermoplastic acrylic resin and thermosetting acrylic resin.
Thermoplastic acrylic resin: Thermoplastic acrylic resin does not undergo further cross-linking during the film formation process, so it has a relatively large molecular weight, good gloss and color retention, water and chemical resistance, fast drying, convenient construction, and easy construction and recoating. And rework, the whiteness and positioning of aluminum powder are good when preparing aluminum powder paint. Thermoplastic acrylic resins are widely used in automobiles, electrical appliances, machinery, construction and other fields.
Thermosetting acrylic resin: Thermosetting acrylic resin refers to having certain functional groups in the structure. When making paint, it forms a network structure by reacting with the functional groups in amino resin, epoxy resin, polyurethane, etc. added. Thermosetting resins generally have relatively large relative molecular weights. Low. Thermosetting acrylic coatings have excellent fullness, gloss, hardness, solvent resistance, weather resistance, no discoloration and no yellowing when baked at high temperature. The most important application is to combine with amino resin to form amino-acrylic baking paint, which is currently widely used in automobiles, motorcycles, bicycles, coiled steel and other products.
The synthesis method of acrylic resin can be classified according to the production method: emulsion polymerization, suspension polymerization, benzene body polymerization, and other polymerization methods.
