Organic silicon sealant for body chassis

Abstract

The invention discloses an organic silicon sealant for a body chassis. The sealant comprises, by weight, 15-30 parts of beta-cyclodextrin grafted polyacrylamide, 10-20 parts of poly(p-dioxanone), 45-55 parts of lignin polyurethane, 5-15 parts of a modifier, 5-15 parts of chitosan quaternary ammonium salt, 25-35 parts of polyhydroxyalkanoate, 30-40 parts of high impact polystyrene, 7-17 parts of a rice hull extract and 6-16 parts of an eucommia extract. Through the above mode, the sealant of the invention has high strength and good compressive property, and is used to effectively enhance safety performance of automobiles.

Description

technical field [0001] The invention relates to the field of sealants, in particular to a silicone sealant for vehicle body chassis. Background technique [0002] Silicone sealant is a kind of silicone rubber polymer material with excellent performance. It has good high and low temperature resistance, excellent electrical insulation, good aging resistance, outstanding surface activity, etc. Inert and other characteristics, it has been widely used in many industries, especially the electrical and electronic and aerospace industries. Due to the many weaknesses of silicone materials, such as low strength, flammability and lack of flame retardant function, its application is limited. With my country's modern industry, the requirements for material properties are becoming more and more stringent. At present, the safety production situation in our country is becoming more and more serious, and the safety requirements for materials are constantly improving. It is of great signifi...
