Problems solved by technology

During the processing of rubber, such as weighing, mixing, semi-finished product molding, vulcanization, post-processing, storage, etc., due to processing needs, such as high-temperature heating, local overheating, etc., N-sub-substances of carcinogens will inevitably be produced or released. Substances such as nitramine are directly discharged into the air. In addition, rubber products are not easy to recycle after vulcanization.

Abstract

The present invention discloses a low-toxicity and harm-free vehicle door-window sealing tape, which comprises, by weight, an ethylene-propylene-diene monomer, carbon black, paraffin oil, calcium carbonate, talc powder, a dispersant, an anti-ultraviolet agent, an antioxidant, an anti-scorching agent CTP, a foaming agent, a nitrogen-free vulcanizing agent, an auxiliary vulcanizing agent, polyethylene glycol, zinc borate, phosphate, and alpha-tocopherol. The low-toxicity and harm-free vehicle door-window sealing tape has characteristics of environmental pollution reducing and reasonable cost maintaining.

Description

[0001] technical field [0002] The invention belongs to the field of automobiles, and in particular relates to a low-toxic and harmless automobile door and window sealing strip. Background technique [0003] The sealing strip materials used in existing automobiles are mainly polyvinyl chloride, thermosetting EPDM rubber, silicone rubber and thermoplastic elastomers, among which polyvinyl chloride and thermosetting EPDM rubber materials account for the vast majority. PVC sealing strips have defects such as poor aging performance, heat resistance, and non-environmental protection. After being assembled on automobile doors and windows for a certain number of years, they will age and crack under sunlight, and cannot achieve a good sealing effect. In the preparation process of thermosetting EPDM sealing strips, it needs to go through banbury mixer and long oven vulcanization, intermittent production, complex process, long production process, high energy consumption, large equipm...
