Functional filling capable of improving wear-resistant property of plastic and rubber and preparation method thereof

Abstract

The invention provides a functional filling capable of improving the wear-resistant property of plastic and rubber, which is characterized in that the raw material of the filling is the fragments generated during jade processing, the silicate compound grains with a laminated structure having an average particle size of 0.5 to 20 micron are obtained after the raw material is grinded, screened, graded and dried, the water content is less than 0.4%, and the functional filling is obtained after activating treatment is done to the silicate compound grains and an coupling agent. Plastic or rubber modified by the functional filling has excellent wear-resisting property, and materials made by which have excellent processing property and excellent mechanical property. The filling is mainly applied to the industries having high requirements on wear-resisting properties such as the PVC plastic wire and cable industry and the rubber conveyer belt industry. The invention is also advantaged in that the fragments produced during jade processing is better used, thereby turning wastes into treasure and reducing environmental pollution effectively. Moreover, the production process is simple and the production cost is low.

Description

technical field [0001] The invention relates to a functional filler capable of improving the wear resistance of plastics and rubber and a preparation method thereof. Background technique [0002] With the rapid development of the plastic and rubber industry, the grades of various functional plastic and rubber products are getting higher and higher, and the demand is also increasing. The performance of existing products can no longer meet the demand. Products and raw materials with high wear-resistant and super wear-resistant plastic rubber have broad application space and market prospects, and meet the development needs of my country's new material market. [0003] At present, to improve the wear resistance of plastics and rubber materials, it is generally to choose high polymer resins with better wear resistance or add resins and fillers with better wear resistance to general-purpose resins. For example, adding polyurethane to PVC can enhance the wear resistance. Abrasiven...

Problems solved by technology

[0003] At present, to improve the wear resistance of plastics and rubber materials, it is generally to choose high polymer resins with better wear resistance or add resins and fillers with better wear resistance to general-purpose resins. For example, adding polyurethane to PVC can enhance the wear resistance. Abrasiveness, but polyurethane is expensive, and only a high blending ratio can have wear resistance, resulting in high product cost; adding common fillers such as calcium carbonate, talcum powder, mica powder, etc. to PVC, PP, rubber, etc. It can improve wear resistance, but because these fillers themselves have low hardness, their wear-resistant modification effect is limited; adding calcium carbonate whiskers and barium sulfate whiskers to PVC, PP, and rubber can improve wear resistance, because the whiskers Special structure, the wear resistance effect of modified plastic rubber is better than that of ordinary fillers, but there are still deficiencies. The whisker material is relatively brittle and easy to break during processing. After being manufactured into products, it still cannot meet the requirements for high wear resistance.
