用途
Apoplications
本品为非污染性防老剂品种之一，在性能上和防老剂MBZ相似，用作天 然胶、丁苯胶、顺丁胶、丁腈胶等合成橡胶，抗热老化作用明显，通常和胺类、酚类防老剂并用具有协同效应，提高耐热氧老化性能，可用于丁晴胶。与促进剂M、DM一起使用时，具有抑制有害金属的加速老化作用。通常用于透明橡胶制品，浅色和艳色橡胶制品。对混炼胶硫化特性的影响明显小于防老剂MB，通常不必因使用本品而调整硫化体系。本品在天 然胶乳发泡制品中可作辅助敏化剂使用，泡沫结构均匀，效果比MB好。
This product is one of non-polluting antioxidant varieties, similar in performance and antioxidant MBZ, used as NR, SBR, BR and other synthetic rubber, anti-thermal aging effect is obvious, it has synergistic effect with Amine and phenol antioxidant to improve the heat and oxygen aging resistance. It can be used in nitrile rubber. When used together with accelerator M and DM, it has the function of inhibiting the accelerated aging of harmful metal. Usually used for transparent rubber products, light-colored and bright-colored rubber products. The effect on curing properties of the compound is obviously less than that of MB, so it is not necessary to adjust the curing system for using this product. This product can be used as auxiliary sensitizer in Natural Latex foaming products. The foam structure is even and the effect is better than MB.
