Abstract

The invention discloses an ultraviolet-resistant organosilicon adhesive which comprises an original silicon adhesive layer and a functional layer. The functional layer comprises the following components in parts by weight: 50-70 parts of organosilicon adhesive, 30-50 parts of hydroxy polysiloxane, 3-5 parts of dibutyltin diacetate, 1.2-2 parts of composite stabilizer, 1-2 parts of lubricant, 5-30 parts of reinforcer, 0.02-0.05 part of pigment, 5-8 parts of toughener and 30-40 parts of ultraviolet absorbent. The ultraviolet absorbent is a chlorobenzotriazole ultraviolet absorbent. By improving the formula, the ultraviolet absorbent and organosilicon adhesive functional layer master batch are mixed and molten by heating, and drawn to form the organosilicon adhesive, thereby solving the problem that color in the organosilicon adhesive in the prior art influences the visual effect. Meanwhile, by the aid of the weather resistance of the organosilicon adhesive, the ultraviolet absorbent can not easily migrate, thereby greatly prolonging the timeliness of the ultraviolet-resistant function.

Description

technical field [0001] The invention relates to 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 differently treated bonding sur...
