preparation example Construction
[0022] The embodiment of the present invention also provides a kind of preparation method of radiation cross-linked chlorinated polyether rubber heat-shrinkable tube, specifically comprising:
[0023] Weigh the raw materials according to the following parts by weight: 85-95 parts of chlorinated polyether rubber, 5-15 parts of chlorinated resin, 30-50 parts of flame retardant, 10-25 parts of flame retardant synergist, and 2-25 parts of antioxidant. 5 parts, 2-5 parts of light stabilizer, 2-5 parts of lubricant, 2-3 parts of cross-linking agent and 1-2.5 parts of toner;
[0024] Add the above components into a high-speed mixer, and mix at a high speed for 5-10 minutes;
[0025] Using the internal mixer or twin-screw extruder to generate the master batch under the condition of 90~170℃;
[0026] Extruding the above-mentioned masterbatch through a single-screw extruder at a temperature of 80-150°C;
[0027] Irradiate the above-mentioned extruded pipe with an electron accelerator,...
Embodiment 1
[0033] The raw materials are weighed according to the following parts by weight: 90 parts of chlorinated polyether rubber (90 kg of copolymerized chloroether rubber), 10 parts of chlorinated resin (10 kg of chlorinated polyvinyl chloride resin), 40 parts of flame retardant ( Specifically, 20kg of decabromodiphenylethane, 20kg of diethylaluminum hypophosphite), 20 parts of flame retardant synergists (specifically, 10kg of zinc borate and 10kg of antimony trioxide), and 4 parts of antioxidant (specifically, antioxidant). agent 10102kg, antioxidant Ky4052kg), 5 parts of light stabilizer (specifically take three (1,2,2,6,6-pentamethylpiperidinyl) phosphite (brand name: GW540) 5kg), lubricant 5 Parts (specifically get methyl silicone oil 2kg, ethylene bis-stearamide 3kg), 3 parts of cross-linking agents (specifically get trimethylolpropane trimethacrylate 3kg) and 2 parts of color powder (specifically get N110 carbon black 2kg) );
[0034] First add the copolymerized chloroether r...
