Abstract

The invention provides polymerization reaction fluorocarbon-based siloxane modified acrylate and a preparation method thereof. Perfluoroalkyl group ethylene, hydrogen-containing siloxane oligomer anddouble-end diacrylate are firstly subjected to a hydrosilation addition under the action of a catalyst, and then hydrophobic and oleophobic polymerization reaction fluorocarbon-based siloxane modifiedacrylate FS is synthesized. The polymerization reaction fluorocarbon-based siloxane modified acrylate can be adopted to prepare a POSS / fluorosilicone co-modified polymethacrylate resin, the glass transition temperature can be increased by 5.41-23.22 DEG C when being compared with that of unmodified PMMA, the contact angle of water on the surface of the resin can be up to 86.27-114.99 degrees, andthe scraping resistance effect is beneficially improved.

Description

technical field [0001] The invention belongs to the technical field of functional acrylates, and in particular relates to a polymerizable reactive fluorocarbon-based siloxane-modified acrylate, a preparation method and an application. Background technique [0002] Polymethyl methacrylate (PMMA), commonly known as plexiglass, is a thermoplastic organic resin material with high light transmittance, good dielectric and electrical insulation properties and easy processing properties. It is used in instrument panels, car lights, Optical lenses, lampshades, curved touch screens, flexible electronic product panels and other fields are widely used, but PMMA resin has low hardness, poor scratch resistance or scratch resistance, and the surface has no waterproof and antifouling performance, which affects the application of the material. Improve. [0003] Cage oligomeric silsesquioxane (POSS for short) has good compatibility with organic materials, good hardness and heat resistance an...
