Embodiment 1
[0034] A rubber sealing strip for automobiles, consisting of the following components in parts by weight:
[0035] 55 parts of EPDM rubber, 8 parts of carbon black, 2 parts of zinc oxide, 2 parts of stearic acid, 5 parts of anti-aging agent 4010NA, 1 part of anti-ultraviolet agent, 3 parts of naphthenic oil, N, N'- m-phenylene bis 8 parts of maleimide, 4 parts of 2-mercaptobenzothiazole, 2 parts of dilauryl thiodipropionate, 2.5 parts of paraffin oil, γ-(methacryloyloxy)propyltrimethoxysilane 1 part, 5 parts of calcium carbonate, 1.5 parts of anti-scorch agent CTP.
[0036] Add the above components into the internal mixer for mixing, and the obtained mixed rubber is then tested for hardness, tensile strength, and elongation at break. Among them, the hardness of the mixed rubber reaches 73 degrees, and the tensile strength reaches 8.5Mpa. , the elongation at break reaches 320%;
[0037] Put the above-mentioned compounded rubber into a mold for thermal kneading and molding, an...
