Abstract

The invention discloses a composite automobile sound insulation cotton adhesive which consists of naphthenic oil, polyisobutylene, a thermoplastic elastomer, tackifying resin and an antioxidant, wherein the composition ratio of the naphthenic oil in the automobile sound insulation cotton adhesive is 10-20%, the composition ratio of the polyisobutylene in the automobile sound insulation cotton adhesive is 5-10%, the composition ratio of the thermoplastic elastomer in the automobile sound insulation cotton adhesive is 20-40%, the composition ratio of the tackifying resin in the automobile soundinsulation cotton adhesive is 40%-60%, and the composition ratio of the antioxidant in the automobile sound insulation cotton adhesive is 0.3%-0.7%. In the invention, various raw materials are fully fused with each other, thus greatly improving the quality of colloid; the naphthenic oil has high density, high viscosity and no toxic or side effects; the polyisobutylene has excellent air tightness and acid and alkali resistance; the tackifying resin improves the adhesiveness of the colloid; and the antioxidant can delay or inhibit polymer oxidation and prolong the service life of the colloid.

Description

technical field [0001] The invention relates to the technical field of automobile sound-insulating cotton, in particular to a composite adhesive for automobile sound-insulating cotton and a preparation method thereof. Background technique [0002] Car sound insulation is based on the performance of the vehicle, the corresponding road conditions, etc., the noise generated by the car engine, the vibration resonance sound generated by the tire and the ground, and the friction sound of the components in the compartment due to gaps or aging extrusion force, etc., to improve the quality of the car. ride comfort. When people choose a car, they not only pay attention to the performance, but also pay more attention to the grade of car accessories; at present, high-end cars are equipped with sound-proof cotton for wheel covers, which can not only insulate sound and heat, but also protect the wheel covers well. When installing the sound insulation cotton, it is necessary to use adhesi...
