Recovering and treating method for glass fibre reinforced plastic waste

Abstract

The recovering and treating method of waste glass fiber reinforced plastic is to treating waste glass fiber reinforced plastic into grains and to utilize the grains as the stuffing for sheet molding compound (SMC). The said method solves the problem of compatibility and adhesion of the waste with resin, reinforcing material and other components and makes SMC possess excellent mechanical performance.

Description

Background technique [0001] The invention belongs to the technical field of composite materials, and in particular relates to a method for recycling and processing glass fiber reinforced plastic waste. Background technique [0002] For decades, FRP has been widely used in various industries due to its light weight, high strength, corrosion resistance and many other excellent properties. However, with the increase in the application time of FRP in my country and the continuous growth of output, the amount of waste such as scraps and old FRP products produced in the production process is gradually increasing. Most of them are treated as construction waste or domestic waste landfill, and the problem of environmental pollution has become increasingly prominent. The recycling and utilization of FRP waste is increasingly on the agenda. [0003] At present, domestic FRP waste is mostly treated as construction waste or domestic waste landfill, and there are also methods of incinera...

AI Technical Summary

Problems solved by technology

Since most FRP products are currently required to be flame retardant, and most FRP products contain a large amount of inorganic fillers and reinforcing materials, it is not ideal to burn as a fuel.

Also due to the limited content of resin in most FRP products, coupled with expensive equipment investment and complicated process, the chemicals that can be extracted by pyrolysis are very limited, at least for now, it is not the best choice
