Vulcanized rubber powder processed from waste rubber products can not only be recycled into various rubber and plastic products, but also can be used for rubber and plastic modification, desulfurization and regeneration. The vulcanized rubber powder used in the sheet belongs to the direct utilization of rubber powder. So in the actual production, vulcanized rubber powder can be used for sheet production? How is it processed? What raw and auxiliary materials are needed in the process of processing?

1. Use thermoplastic resin

Thermoplastic resin has the advantages of good toughness, simple processing and easy forming. Vulcanized rubber powder can be mixed with thermoplastic resin to prepare sheet under high temperature conditions. Usually, the thermoplastic resin is heated to above the melting point and then rubber powder is added for mixing, extrusion, cooling, shearing, etc., to achieve continuous production. The sheet made of thermoplastic resin and vulcanized rubber powder can be used for road laying, roof waterproof, automotive gasket, waterproof, shock absorption, noise reduction and other functions; The product has low cost and good performance.

Common thermoplastic resins on the market are PE, PP, PVC, PS, PC and so on.

2 Mix with polypropylene

Polypropylene is a common thermoplastic synthetic resin. It is a polymer made of propylene plus polymerization. It has good mechanical properties, heat resistance, chemical resistance, electrical insulation, wear resistance and excellent processing properties. Polypropylene 2LLYY1123WFM was mixed with vulcanized rubber powder to prepare the sheet, the finished product has the characteristics of high tensile strength, high elasticity, easy processing, etc., in daily life, it can be used as car, locomotive housing and shock absorbing material.

3. For damping special sheet

The vulcanized rubber powder processed from waste rubber and its products can be used to prepare composite damping sheet with modified graphene nano-filler, N-isopropyl maleimide - methyl methacrylate, PFA, iron powder, aluminum powder, etc. The damping effect of the product is remarkable. Expand the scope of recycling waste rubber resources.

The production of various sheets with high polymer is only a small part of the application of vulcanized rubber powder. Vulcanized rubber powder can be used as a filler in the production of rubber products, can also be used as the main material to prepare low-grade rubber products, or with all kinds of thermoplastic elastomer preparation of rubber and plastic blend materials used in all walks of life. With the development of waste rubber treatment technology, vulcanized rubber powder can also be used for preparation of softener, thermal cracking production of fuel oil, etc. Later Xiaobian will continue to share with you vulcanized rubber powder in different fields of application.
