Problems solved by technology

After research, it is found that the storage stability of such inorganic particles is poor, which is not conducive to the production and the stability of the resin in the later stage. Moreover, the existence of inorganic particles itself will greatly reduce the transparency of the coating, which is very important for anti-fog coatings. is fatal

Abstract

The invention belongs to the technical field of polymer polymerization, and discloses a silicon-titanium hybrid acrylate polymer and double-cured paint prepared therefrom. The silicon-titanium hybridacrylate polymer is obtained by the following steps: adding an acrylate monomer, a silane coupling agent, a hydroxyl group-containing acrylate monomer and a carboxyl group-containing acrylate monomerinto an initiator for free radical polymerization to obtain a carboxyl group-containing prepolymer; then adding p-hydroxyanisole and triphenylphosphine, and using glycidyl methacrylate to react with acarboxyl group in the main chain of the carboxyl group-containing prepolymer to introduce a double bond and obtain an organosilicon hybrid acrylate prepolymer; and then adding a titanate monomer, andstirring at room temperature with humidity being not more than 30%. The invention provides silicon-titanium hybrid acrylate which is capable of double curing. The paint has both excellent continuousanti-fog property and boiling water resistance after being cured into a film.

Description

technical field [0001] The invention belongs to the technical field of macromolecule polymerization, and more specifically relates to a silicon-titanium hybrid acrylate polymer and a dual-curing coating prepared therefrom. Background technique [0002] In daily life, there will be obvious temperature and humidity differences on both sides of some transparent parts (such as glass and some transparent plastics). The water vapor in the air will condense on the higher temperature side to form small droplets with poor fluidity and form fog. The fog on the surface of the substrate will cause irregular scattering, reflection, diffuse reflection and diffraction of light, thereby reducing the transmission ability of light. These originally transparent parts become blurred, and sometimes even cause great harm, so preventing the generation of fog is particularly important in production and life. In order to solve these problems, the surface of the material is generally modified by hy...
