Abstract

The invention provides a short-fluorocarbon-chain acrylate polymer. The short-fluorocarbon-chain acrylate polymer is prepared from a short-fluorocarbon-chain acrylate monomer, an acrylate monomer, a vinyl-containing organosilicon monomer and an acrylic monomer through solution polymerization. The invention also provides a fluorine-containing resin release agent composition taking the short fluorocarbon chain acrylate polymer as a main body, the fluorine-containing resin release agent composition has good degradability, and the use of PFOA / PFOS substances is avoided. The release agent composition is uniform in film forming on the surface of a mold, short in demolding time, long in demolding life, not prone to high-temperature glue flowing, easy to remove from the surface of a finished product to be demolded, excellent in demolding performance and capable of being applied to the technical field of demolding of thermosetting resin, thermoplastic resin, various rubber workpieces and the like.

Description

technical field

[0001] The invention relates to the field of demoulding technology for thermosetting resins, thermoplastic resins and various rubber parts, in particular to a short fluorocarbon chain acrylate polymer, a preparation method thereof, and an application in a high-performance demoulding agent composition. Background technique

[0002] The release agent is a functional substance between the mold and the molded product, and is often used in metal die-casting, polyurethane foam and elastomer, glass fiber reinforced plastics, injection molding thermoplastics, vacuum foamed sheets and extruded profiles, etc. In various molding operations, it is a type of processing aid that prevents molded products, laminated products, etc. from adhering to molds or other board surfaces, and acts as a type of processing aid that is easy to detach.

[0003] In the field of polymer molding and processing, the use of release agents is essential. Traditionally used as release agents are m...
