Example Embodiment
[0036] The embodiments of the present invention will be described in detail below.
[0037] The production process of EPDM rubber microporous backing plate is characterized by the following steps:
[0038] S1: Put the EPDM rubber into the kneader and knead for 30-40 seconds, then put zinc oxide, stearic acid, carbon black, moisture absorbent, acid-base regulator, softener and inorganic filler into the kneader Kneading for 5-10 minutes, the debinding temperature is 115-130℃, to obtain the masterbatch;
[0039] S2: Put the masterbatch prepared in S1 into the open mill, add vulcanizing agents, accelerators, foaming agents, and foaming aids, and after mixing uniformly, open the cooling water circulation system of the mill to make the milling process, The temperature of the mixture in the open mill does not exceed 45°C. Adjust the roller pitch to 0.8-1.3 mm for thinning, tap the triangle bag 3-4 times, and then adjust the roller pitch to 5-6 mm for discharging. Mix rubber and park the r...
