Rubber self-adhering type composite damping material for motorcycles and method of manufacturing the same

Abstract

A locomotive-used rubber system self-adhesive composite damp material and the manufacture method thereof at least comprises a layer of self-adhesive damp material layer; one surface of the self-adhesive damp material layer is attached with a protection layer for protecting the self-adhesive damp material; the other surface of the self-adhesive damp material layer is attached with a layer of installation isolation paper. The damp material layer is a composite rubber material layer with the rubber dosage ranging from 50 to 100 measured by weight, liquid colophony dosage ranging from 100 to 300 and the flame retardant and other filling material dosage ranging from 100 to 300. The rubber can be butyl rubber, halogenated butyl rubber and acrylonitrile-butadiene rubber; the liquid colophony can be polybutylene liquid glue and butyronitrile liquid glue; the flame retardant is the normal flame retardant; the other inorganic filling material is isinglass powder, calcium carbonate and aluminum hydroxide; the protection layer is a flexible layer which can not be torn, made of the aluminium foil, glass fiber cloth, leatheroid or paper material. The installation isolation paper can be the paper layer which can be torn.

Description

technical field

[0001] The invention relates to a vibration and noise reduction material and a manufacturing method thereof. In particular, a rubber-based damping sheet with good self-adhesive performance and high damping performance, which is applied on the shell of a locomotive and used to isolate noise due to locomotive vibration, and its manufacturing method is mainly used to suppress vibration and sound insulation. The effect of vibration and noise reduction. It belongs to the field of shock-absorbing materials. Background technique

[0002] Rubber damping sheet is a product that uses rubber as the main organic component and a large amount of inorganic substances as fillers to reduce vibration and noise through blending, extrusion, and calendering. Due to the good damping properties of rubber, rubber damping sheets are widely used in the field of vibration and noise reduction materials. It is usually used in automobiles, trains, ships, airplanes, construction machine...
