【摘要】 对增塑聚氯乙烯(PVC)、顺丁橡胶(BR)硫化胶、苯乙烯-丁二烯-苯乙烯(SBS)热塑性橡胶三种材料的表面硬度与温度之间的关系进行测试与研究，并使用邵氏A型和D型硬度计表征上述三种材料的表面硬度。测试结果表明，增塑PVC和SBS热塑性橡胶表面硬度对温度较敏感，特别是增塑PVC,因此在应用时须考虑使用温度。更多还原

【Abstract】 The relationship between temperature and surface hardness of three different materials which were plasticized polyvinyl chloride(PVC),butadiene rubber(BR)vulcanizate and styrene-butadiene-styrene(SBS)thermoplastic rubber was tested and researched. Shore A and D hardness testers were used to characterize the surface hardness of the above three materials. It was found that the surface hardness of plasticized PVC and SBS thermoplastic rubber,especially that of plasticized PVC,was sensitive to temperature,therefore,the use temperature must be considered when applying these two materials.更多还原
