Abstract

The invention discloses a manufacturing process for uvioresistant organic silica gel. The manufacturing process comprises the following steps that 1, by weight, organic silicon adhesive, hydroxide polysiloxane, dibutyl tin diacetate , compound stabilizer, lubricant, 5-30 parts of enhancer, 0.02-0.05 part of pigment, 5-8 parts of flexibilizer and 30-40 parts of ultraviolet light absorber are made into paste, and the upper surface of an original silica gel layer is coated with the paste in a one-off mode, wherein the ultraviolet light absorber is chlorinated benzotriazole type ultraviolet light absorber; 2, thermo curing and photo curing are conducted on the coated original silica gel layer, so that the uvioresistant organic silica gel is obtained, the thermo curing temperature ranges from 80 DEG C to 120 DEG C, and the thermo curing time ranges from 10S to 30S. By means of the manufacturing process, the formula is modified, the method that the ultraviolet light absorber and organic silica gel function layer parent stock are mixed, heated and molten and then are drawn to form the organic silica gel is adopted, and the problems that in the prior art, organic silica gel is colored, and the visual effect is affected are solved. By means of the weather resistance of the organic silica gel, the ultraviolet light absorber is not prone to transferring, and the timeliness of the uvioresistant function is greatly prolonged.

Description

technical field [0001] The invention relates to a manufacturing process of an anti-ultraviolet organic silica gel. Background technique [0002] The adhesive of the silicone adhesive is a linear high molecular mass prepared by one or several linear, cyclic or branched siloxanes under the action of a catalyst through reactions such as equilibrium, addition or condensation. Or cross-linked siloxane composition. There are mainly two types of silicone adhesives: rubber type and resin type. Silicone adhesives have the characteristics of high temperature resistance, stable adhesion and good durability, and are widely used in various fields such as aviation, navigation, spacecraft, rockets and missiles, atomic energy, and electronic and electrical industries. [0003] With the gradual expansion of the application range of silicone adhesive tapes, all walks of life have put forward new requirements for the quality and properties of silicone adhesive tapes. Many irregular and diff...
