Acrylic resins are classified by production method
Oct 16, 2018

1. Emulsion polymerization: It is obtained by reacting a monomer, an initiator and distilled water together. Generally, the resin is a 50% solid emulsion, and is a latex solution containing about 50% water. The synthesized emulsions are generally milky white bluish (Dingdal phenomenon), and the glass transition temperature is designed according to the FOX formula. Therefore, this type of emulsion has a large molecular weight, but the solid content is generally 40% to 50%. The production industry requires precise control, due to the use of water as a solvent, environmentally friendly emulsion.

2. Suspension polymerization: It is a relatively complicated production process and is a method used for the production of solid resins. The solid acrylic resin is subjected to a reaction polymerization using a methyl group-containing acrylate. The acrylates with a methyl group generally have a certain functional group, and the polymerization reaction in the reaction vessel is not easy to control, and it is easy to stick to the blasting pot.

3. Bulk polymerization: It is a highly efficient production process. The process is to put the raw materials into a special plastic film, then react into agglomerates, take out the pulverization, and then filter. The purity of the solid acrylic resin produced by this method is the highest in all production methods, and the product is stable. Sex is also the best, and its shortcomings are also full.
