摘  要:介绍耐热105℃PVC电线电缆绝缘料的配方和性能。通过对基础树脂、填料、增塑剂、稳定剂、润滑剂、抗氧剂等的筛选和用量试验表明,选用齐鲁公司生产的PVCS-1300为基础树脂,以煅烧陶土(300目)为填料,偏苯三酸三辛酯(TOTM)作增塑剂,邻苯二甲酸铅类或三盐基硫酸铅和二盐基亚磷酸铅复配物作稳定剂,PbSt和BaSt复配物作润滑剂,双酚A作抗氧剂,所制电缆料的性能远超过国标要求的耐热105℃PVC电缆料的标准,尤其是抗氧剂双酚A的加入,使电缆料的热老化性能达到国标的要求。具体配方为:PVCS-1300100质量份(下同),锻烧陶土10份,TOTM50份,三盐基硫酸铅4份,二盐基亚磷酸铅3份,PbSt1份,BaSt0.5份,双酚A0.5份。The property and formula of PVC compound for cable insulating material with heat resistance of 105℃ are described in this paper.The results of the tests on base resin,filler,plasticizer,stabilizer,lubricant,antioxidaant and content showed when PVC S1300 produced by Qilu Co was used as base resin,burnt pottery clay (300mesh) as filler,TOTM as plasticizer,phthalic lead or the compound of tribasic lead sulfate with bibasic lead phosphite as stabilizer,compound of Pbst with Bast as lubricant,bisphenol A as antioxidant,the properties of the prepared PVC compound were much better than those required by national standard for PVC compound for cable insulating material with heat resistance of 105℃.The application of bisphenol A to the compound made the thermal ageing properties come up to the level required by national standard.The formula was as follows:PVC S1300 100 parts(by mass,the same below),burnt pottery clay 10 patrs,TOTM 50 parts,tribasic lead sulfate 4 parts,bibasic lead phosphite 3 parts,Pbst 1 part,Bast 0.5 part and bisphenol A 0.5 part.
