Abstract

The invention discloses an automobile skylight sealing foaming adhesive tape and a preparation method thereof. The automobile skylight sealing foaming adhesive tape comprises ethylene propylene dienemonomer 5527 type, carbon black N550 type, paraffin oil, calcium carbonate, zinc oxide, stearic acid, anti-aging agent MB, accelerant PZ, accelerant M-75, accelerant CZ, accelerant TMTD, vulcanizing agent DTDM, sulphur powder and foaming agent R-380. The preparation method comprises the following steps of burdening, banburying, open milling, extrusion, vulcanization and cutting. The automobile skylight sealing foaming adhesive tape has the advantages of simple formula and production technology, short vulcanization time, good sealing performance and high production efficiency and can be used for a long time, and a water leakage phenomenon can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of rubber material sealing, in particular to an automobile sunroof sealing foam rubber strip and a preparation method thereof. Background technique [0002] In the modern industrial field, sealing technology plays a pivotal role, and sealing failure will not only greatly increase subsequent maintenance costs, but may also lead to fatal disasters. Material properties are the decisive factors for the performance of sealing products. In the field of automobiles, automobile sealing strips are one of the important parts of automobiles. They are widely used in parts such as doors, windows, body, seats, sunroofs, engine boxes and trunks. They have the functions of waterproof, sealing, sound insulation, dustproof, It plays an important role in antifreeze, shock absorption, heat preservation and energy saving. [0003] In recent years, with the rapid development of the automobile industry and the diversification of...
