Example Embodiment
[0024] Example 1
[0025] A chlorinated polyethylene rubber composite new material, which is composed of: 100kg of rubber-type chlorinated polyethylene, 7kg of magnesium hydroxide, 35kg of semi-reinforced 774 carbon black, 60kg of 990 carbon black, 0.5kg of stearic acid, stearic acid Calcium 2kg, kaolin E2 15kg, dioctyl terephthalate 25kg, protective wax 0.5kg, antimony trioxide 4kg, thiadiazole vulcanizing agent ECHO S 8083M-504.5kg.
[0026] The preparation method of chlorinated polyethylene rubber sealing strip is:
[0027] (1) Weigh chlorinated polyethylene rubber and various additives according to the formula;
[0028] (2) Put the auxiliaries except the vulcanizing agent and the weighed chlorinated polyethylene rubber into the internal mixer, and control the rubber mixing temperature by cooling water to be less than or equal to 100 °C. After mixing for 3 minutes, add the vulcanizing agent and then After mixing for about 1.5 minutes, the material is discharged, and 4-5 t...
