Abstract

The invention provides a PVB material with good tensile strength. The PVB material comprises the following raw materials, by weight: 55-65 parts of PVB resin, 10-20 parts of a hybrid-based strength agent, 5-10 parts of an active filler, 1-5 parts of a cross-linking agent and 1-2 parts of a photoinitiator. The PVB material disclosed by the invention is prepared from the PVB resin, the hybrid-basedstrength agent, the active filler and other raw materials, and the PVB material is subjected to proton irradiation in the preparation process, so that the photoinitiator is promoted to exert the blending effect of the hybrid-based strength agent, the PVB resin and other raw materials, the cross-linked mesh degree of the product is improved, and the strength and other properties of the product arefurther improved.

Description

technical field [0001] The invention relates to the technical field of PVB materials, in particular to a PVB material with good tensile strength and a preparation method thereof. Background technique [0002] Polyvinyl butyral (PVB) resin is a hot-melt polymer compound with high transparency and flexibility, and has good bonding performance with glass, metal, ceramics and other materials. PVB film is made by PVB resin The material is extruded under the action of a plasticizer. It is generally used as a gasket for laminated glass. The appearance is a translucent film without impurities. The surface is flat and has a certain roughness and good flexibility. It has cold resistance and heat resistance. , moisture resistance, high mechanical strength, etc., and has good adhesion to inorganic glass. [0003] Existing PVB materials have little research in the field of tensile strength, and the raw materials used are mostly a combination of PVB resin and tensile and other additives,...
