摘要
Abstract
To reduce the loss of materials due to material flying during the compounding process of insulating materials and the pollution of materials to the environment,combined with the feature that low-melting-point feeding bags of EVA and POE could be compounded together with raw materials and have no significant impact on the performance of insulating layer compounding rubber and vulcanized rubber within a certain usage range,the influence of low-melting-point feeding bags on the mechanical,ablation and vulcanization properties of EPDM insulating layer was studied.The test results show that as the amount of EVA or POE material increases,the torque difference and vulcanization rate index Vcof the insulation layer gradually decreases,and the process vulcanization time t90 is prolonged.EVA or POE materials do not participate in the peroxide vulcanization reaction.With the increase in the amount of POE,the tensile strength and elongation rate at break of the insulation layer significantly increases,but the amount of EVA had no significant effect on the mechanical properties of the insulation layer.With the increase in the amount of POE or EVA materials,the ablation performance of the insulation layer do not change significantly.关键词
