Abstract

The invention provides butyl rubber sealing tape used for an automobile. The butyl rubber sealing tape is prepared from, by weight, 15-20 parts of butyl rubber, 6-10 parts of nanoscale calcium carbonate, 30-40 parts of light calcium carbonate, 2-5 parts of acticel, 10-20 parts of low-molecular-weight polyisobutene, 4-10 parts of middle-molecular-weight polyisobutene, 4-10 parts of high-molecular-weight polyisobutene, 6-10 parts of pigment and 8-15 parts of petroleum resin. One face of the provided butyl rubber sealing tape used for the automobile is bonded with an automobile steel plate, and the other face is bonded with a plastic moisture-proof film to have the waterproof effect. Experiment results show that performance indexes of the butyl rubber sealing tape used for the automobile reach or exceed those of existing similar products, the butyl rubber sealing tape used for the automobile has the advantages that airtightness is good, the sealing tape is resistant to high temperature and does not flow, and the bonding strength is not lowered at low temperature.

Description

technical field [0001] The invention relates to the technical field, in particular to a butyl rubber sealing tape for automobiles and a preparation method thereof. Background technique [0002] Butyl rubber has excellent air tightness and good adhesion, low temperature resistance, aging resistance and other characteristics, and is widely used in waterproof and airtight, shock-absorbing bonding and sealing, such as stationery bonding, building materials bonding and sealing Waterproof, shock-absorbing bonding and sealing of machinery and equipment, airtight bonding of material joints, etc., are a kind of bonding and sealing materials that are easy to use, widely used, safe, reliable, economical and practical. [0003] Butyl rubber sealing tape is widely used in the automotive field and construction industry because of its excellent air tightness, water tightness, good adhesion, aging resistance, low temperature resistance, water resistance, convenient construction and installa...
