Abstract

The invention discloses a butyl rubber foam tape which comprises an adhesive, a base material and a primer. The adhesive and the primer are coated on two sides of the base material respectively, the adhesive comprises, by weight, 28-45% of butyl rubber, 23-37% of a plasticizer, 20-46% of a tackifier and 2-7% of fillers, ethylene-propylene-diene monomer (EPDM) foam is adopted for the base material, and a K-500 primer is adopted for the primer. According to the butyl rubber foam tape, the adhesive with the butyl rubber as a main component has good ageing resistance, high temperature resistance and low temperature adhesion, and the foam tape is better than other foam tapes in waterproofness and air tightness; the foam tape is in a soft state due to addition of the plasticizer, initial adhesion and peel strength of the foam tape are increased due to addition of the tackifier, the cost is low, mass production is facilitated, and the foam tape can be widely applied to automobiles.

Description

technical field [0001] The invention relates to the field of adhesive tapes used in automobiles, in particular to a butyl rubber foam adhesive tape. Background technique [0002] Traditionally, the fixed connection between the interior and exterior of the car and the car is fixed mechanically, but there are many deficiencies in the mechanical fixation. Mechanical fixing needs to reserve mounting holes on the car, which cannot be effectively sealed against wind, rain, dust and noise, and corrosion may occur. Too many mechanical parts are installed on the car, which increases the overall quality of the car and increases the fuel consumption of the car. It is neither economical nor environmentally friendly. [0003] Now more and more foam tapes are applied to the fixing between the interior and exterior of the car and the car, which has an excellent effect on improving the sealing performance of the car and reducing the quality of the car. However, when the car is washed, it ...
