Embodiment 1
[0019] Example 1: Preparation of Salt Corrosion Resistant Cable Insulation Rubber
[0020] Raw material weight ratio:
[0021] EPDM rubber, 55 parts; butadiene rubber, 15 parts; polysulfide rubber, 10 parts; isothiazolinone, 5 parts; methacrylamide, 8 parts; methyl benzotriazole, 3 parts; Sodium hexametaphosphate, 2 parts; Mercaptoethanol, 2 parts; Triallyl isocyanurate, 3 parts; 2-Mercaptobenzimidazole, 1 part; The weight ratio of sodium hypophosphite is 3:1.
[0022] Preparation:
[0023] Step S1, uniformly mixing EPDM rubber, butadiene rubber, and polysulfide rubber to obtain a main material, placing the main material in a single-screw extruder for blending, and granulating to obtain a base resin;
[0024] Step S2, open the internal mixer and preheat it to 50-55°C, then add the base resin obtained in step S1 for banburying, the banburying time is 4-6 minutes, and the mixture 1 is obtained;
[0025] Step S3, adding isothiazolinone, methacrylamide, tolyltriazole, sodium h...
