脱模剂MK529/11在轮胎生产中的应用

Application of Mold Release Agent MK529/11 in Tire Production

针对轮胎硫化脱模时存在的轮胎粘上模造成的肩部薄胶边、钢丝圈弯曲等问题,研究不同脱模剂在轮胎生产中的应用效果。结果表明:脱模剂MK529/11和进口脱模剂B为水性产品,无胶料隔离问题,对轮胎外观无不良影响,且为中性产品,不腐蚀模具;脱模剂MK529/11每班基本喷涂1次,可解决轮胎粘上模问题,肩部胶边可与轮胎一起脱下,胎肩垫伤缺陷率降低了57.44%。

Aiming at the problems of thin rubber edges on the molded tire shoulders and bending of the wire bead caused by the sticking of the tire on the upper mold during tire vulcanization and demolding,the application effects of different mold release agents in tire production were studied.The results showed that the mold release agent MK529/11 and imported mold release agent B had no compound isolation problem and no adverse effect on the tire appearance,and they were water-based neutral products that did not corrode the molds.With MK529/11,the problem of tire sticking on the upper mold was solved,the shoulder rubber edge could be taken off together with the tire,and the defect rate of shoulder damage was reduced by 57.44%.In addition,the mold release agent MK529/11 was basically sprayed only once per shift.
