The 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, as well as desulfurization and regeneration. Among them, the use of vulcanized rubber powder in the sheet is the direct utilization of rubber powder. So in actual production, which sheet materials can vulcanized rubber powder be used for? How is it processed? What raw and auxiliary materials are needed in the process?
1. Combined use of thermoplastic resin
Thermoplastic resin has the characteristics of good toughness, simple processing and easy molding. The vulcanized rubber powder can be mixed with thermoplastic resin under high temperature conditions to prepare sheets. Usually, the selected thermoplastic resin is heated to above the melting point and then the 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 paving, roof waterproofing, automobile gaskets, etc., playing the role of waterproofing, damping, and silencing; the product has low cost and good performance.
Common thermoplastic resins on the market include PE, PP, PVC, PS, PC, etc.
2. Mix with polypropylene
Polypropylene is a common thermoplastic synthetic resin. It is a polymer formed by the addition polymerization of propylene. It has good mechanical properties, heat resistance, chemical resistance, electrical insulation, abrasion resistance, and processing properties. The sheet is prepared by mixing polypropylene 2LLYY1123 with vulcanized rubber powder. The finished product has the characteristics of high tensile strength, high elasticity, and easy processing. In daily life, it can be used as automobile and locomotive covers and shock absorption materials.
3. Used for damping special sheet
The vulcanized rubber powder processed from waste rubber and its products can be combined with modified graphene nano-fillers, combined with N-isopropyl maleimide-methyl methacrylate, PFA, iron powder, aluminum powder, etc. to prepare composite damping sheets The product has a significant damping effect; expand the scope of recycling of waste rubber resources.
The production of various sheets with high molecular polymers 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, and can also be used as the main material to prepare low-grade rubber products, or to prepare rubber-plastic blend materials with various thermoplastic elastomers for use in various industries. With the continuous development of waste rubber processing technology, vulcanized rubber powder can also be used for softener preparation, thermal cracking to produce fuel oil, etc. Later editors will continue to share with you the application of vulcanized rubber powder in different application fields.
