Embodiment 1
[0026] The active agent is nano-zinc oxide, and the particle size of the nano-zinc oxide is 20-80nm.
[0027] The anti-aging agent TMQ is 2,2,4-trimethyl-1,2-dihydroquinoline polymer.
[0028] The mixing method of the above-mentioned carcass compound composition comprises the following steps:
[0029] 1. One-stage mixing: control the temperature of the internal mixing chamber of the internal mixer to 35°C, and the rotor speed to 80r.min -1 , then add 100 parts of natural rubber, 1 minute later, add 8 parts of nano zinc oxide, 1 part of anti-aging agent 4020, 0.9 parts of anti-aging agent TMQ, 20 parts of adhesive GLR, after 1.5 minutes, add 56 parts of carbon black N326, 3 Deglue after minutes;
[0030] 2. Two-stage mixing: Add the above-mentioned degumming, 70204.5 parts of insoluble sulfur, 1.25 parts of accelerator DZ, 0.2 parts of anti-scorch agent CTP, 5 parts of adhesive RA65 in the open mixer, thin pass 5 times, and the next film .
