| 硫化系统选用普通硫黄硫化系统，胶猜中含有较多的多硫键，使胶料在热氧老化阶段功能下降过快，没等构成炭化层就失掉使用价值。而选用硫黄给予体，胶猜中单硫键和双硫键占90以上，胶料热氧老化阶段功能下降不大，能够构成炭化层。 The vulcanization system chooses ordinary sulfur curing system. There are more sulfur bonds in the rubber guess, which makes the function of the compound decline too fast in the thermal-oxygen aging stage. Without carbonization layer, it loses its use value. When the sulfur donor was selected, the monosulfur bond and disulfide bond accounted for more than 90% in the rubber guess, and the function of the compound in the thermal-oxidative aging stage declined slightly, which could form a carbonized layer. 硫黄和促进剂TMTD用量对掩盖胶功能的影响能够看出，当硫黄和促进剂TMTD用量别离为0．2和2．3份时，掩盖胶综合物理功能较好，炭化层寿数最长。此外，为使炭化层龟裂均匀，还应进步胶料的导热功能，因而适当进步氧化锌用量，通过实验断定氧化锌用量为l9份。硫黄和促进剂TMTD用量对掩盖胶功能的影响 The effect of sulfur yellow and TMTD dosage on masking glue function can be seen that when sulfur yellow and TMTD dosage are 0.2 phr and 2.3 phr respectively, the comprehensive physical function of masking glue is better, and the longest life of carbonized layer is obtained. In addition, in order to make the carbonized layer crack evenly, the thermal conductivity of the compound should be improved, so that the amount of zinc oxide should be appropriately increased, and the amount of zinc oxide should be L9 phr.
