预分散橡胶助剂母胶粒/片的质量控制

Quality Control of Rubber Additive Masterbatch

简介预分散橡胶助剂母胶粒/片的质量控制。金属氧化物、短纤维、硫化剂、促进剂、防焦剂、防老剂、发泡剂和粘合剂等橡胶助剂可制成预分散母胶粒/片。预分散橡胶助剂母胶粒/片的载体有丁苯橡胶、天然橡胶、顺丁橡胶、氟橡胶等通用橡胶和特种橡胶。预分散橡胶助剂母胶粒/片的质量控制要点为:橡胶助剂的有效成分含量高,粒径小、分布窄,分散性良好。预分散橡胶助剂母胶粒/片的塑性和隔离效果好,高温下不结块、不粘连。

The quality control of rubber masterbatch with pre-dispersed additive was introduced. The additives included metal oxides, short fibers, curing agents, accelerators, retarders, antioxidants, blowing agents and tackifiers. The rubber carriers could be general purpose rubber such as styrene butadiene rubber, natural rubber and butadiene rubber, and specialty rubber such as fluororubber. High quality masterbatch possessed high content of additive, small particle size, narrow distribution and good dispersion of additives. The experimental results showed that the plasticity and anti-block property of the masterbatch were good.
