Abstract
The present invention discloses a vehicle rubber sealing strip, which comprises, by weight, an ethylene-propylene-diene monomer, 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, a terpene resin, zinc borate powder, phosphate, and alpha-tocopherol. The low-harm and toxicity-free vehicle sealing strip has characteristics of environmental pollution reducing and reasonable cost maintaining.
Description
[0001] Technical field [0002] The present invention belongs to the automotive field and involves a car rubber seal. Background technique [0003] The sealing materials used in the existing cars are mainly polyvinyl chloride, thermosetal triaben acelene rubber, silicon rubber and thermoplastic elastic body, which account for most of the polyvinyl chloride and thermosetable triabin meal rubber.Polyvinyl chloride sealing strips have defects such as poor aging performance, heat resistance, and environmental protection. After the use of a certain period of time on the car doors and windows, it will be aging and cracked under the sun, and it will not have a good sealing effect.During the preparation process of thermosetable ternary ethylene rubber sealing, it needs to be refined with secret refining and long oven, gap production, complicated process, long production process, high energy consumption, large equipment investment, and a certain amount of environment for the environment.P...
