Embodiment 1
[0011] Firstly, 39% CPE rubber, 12% carbon black, 18.5% talc powder, 8.5% light calcium carbonate are blended, and in an internal mixer, the temperature of the stick is 45~60℃ for 27~40min; then add sunflower Dioctyl diacid 4.3% and chlorinated paraffin 4.5%, then add 2.5% accelerator, continue mixing for 3 minutes; then blend with 1.2% paraffin, 2.0% magnesium oxide, 3.0% antimony trioxide, 2.0% decabromide , Continue to mix in the internal mixer for 3 minutes, then add 2.5% DCP vulcanizing agent to mix for 0.5 minutes in the internal mixer, and finally discharge the rubber from the internal mixer, and then unload and pack in the open mixer to obtain the finished product.
Embodiment 2
[0013] First, 37% CPE rubber, 12.5% carbon black, 17.9% talc, and 7.5% light calcium carbonate are blended, and then mixed in an internal mixer at a temperature of 45~60℃ for 27~40min; then add sunflower Dioctyl diacid 4.5% and chlorinated paraffin 5%, then add 2.0% accelerator, continue banburying for 3 minutes; then blend with 2% paraffin, 2.5% magnesium oxide, 3.5% antimony trioxide, and 2.6% decabromide , Continue to mix in the internal mixer for 3 minutes, then add 3.0% DCP vulcanizing agent and mix for 0.5 minutes in the internal mixer, and finally discharge the rubber from the internal mixer, and then unload and pack in the open mixer to obtain the finished product.
Embodiment 3
[0015] First, 40% CPE rubber, 13% carbon black, 16.2% talcum powder, 6.0% light calcium carbonate are blended, and the mixer is mixed at a temperature of 45-60°C for 27-40 minutes; then add sunflower Dioctyl diacid 6% and chlorinated paraffin 4%; then add 3.0% accelerator, continue banburying for 3 minutes; then blend with 3.0% paraffin, 1.8% magnesium oxide, 2% antimony trioxide, 1.8% decabromide , Continue to mix in the internal mixer for 3 minutes, then add 3.2% DCP vulcanizing agent and mix for 0.5 minutes in the internal mixer, and finally discharge the rubber from the internal mixer, and then unload and pack it in the open mixer to obtain the finished product.
[0016] Table 1 is the technical index of Example 1. It can be seen that the performance index greatly exceeds the requirement.
