Abstract

The invention relates to the field of material synthesis, and provides a preparation method of a high-performance rubber product. Zinc oxide and organic zinc are uniformly deposited onto the rubber main reinforcing material by a physical or chemical process to form the zinc-oxide / organic-zinc-coated reinforced composite material. The composite material is directly added in the rubber compounding link; and the zinc oxide implements nano dispersion in the rubber master batch by the aid of the reinforcing material, thereby effectively avoiding the quality problems of gelling, scorching and the like caused by zinc oxide aggregation, and reducing the consumption of the zinc oxide in the rubber product.

Description

technical field [0001] The invention relates to the field of material synthesis, in particular to a preparation method of high-performance rubber products. Background technique [0002] Zinc oxide is usually used as a vulcanization activator in rubber production and is an essential raw material in rubber production. Zinc oxide is very easy to mix in rubber, but zinc oxide and raw tape have the same negative charge, they repel each other during mixing, and it is extremely difficult to disperse, so it is necessary to increase the amount of zinc oxide in the rubber processing process, sometimes resulting in rubber compound Gel or scorch, and the use of excessive zinc oxide will release a large amount of zinc, which is a potential hazard to the environment and human body. The EU 2003 / 105 / EC regulation restricts the use of ordinary zinc oxide in electrical and electronic equipment, and it is imperative to reduce the amount of zinc oxide in rubber. Improving the dispersibility o...
