Problems solved by technology

[0003] At present, most of the waste of FRP is treated as domestic waste landfill, and some are burned, pyrolyzed or crushed as fillers, etc. This kind of treatment not only causes a huge waste of resources, but also has a great impact on the environment.

Embodiment Construction

[0012] The present invention will be further described through the following examples. This example is a kind of the present invention, and the present invention should not be limited to the contents specifically described in this example.

[0013] In the first step, the FRP waste is cut, rolled, crushed, and ground into a powder with a fineness of 400 mesh;

[0014] In the second step, the powder prepared in the first step is mixed with PE and grafting agent (maleic anhydride) according to the weight ratio of 35:55:10, and stirred evenly;

[0015] The third step is to put 250kg of the above mixture into the high temperature room of the rotomolding equipment for melting and grafting. The temperature is controlled within the range of 240-250°C. After 1 hour, the graft copolymer (FRP / PE) can be produced Material, namely FRP / PE plastic alloy material.

Abstract

Offal and waste and old glass fiber-reinforced plastic garbage produced in production are increased rapidly with continuous development of a glass fiber-reinforced plastic industry, and thus severe pollution on the air environment and the earth's surface environment is produced. The invention provides a recycle method of glass fiber-reinforced plastic waste, and a fiber-reinforced plastic (FRP) / polyethylene (PE) plastic alloy material. The recycle method of glass fiber-reinforced plastic waste has simple production processes. The recycle method of glass fiber-reinforced plastic waste realizes reasonable resource utilization. Through recycle method of glass fiber-reinforced plastic waste, FRP, PE and a grafting agent are mixed according to a certain part ratio and the mixture is subjected to melt grafting in a high-temperature room to produce a graft copolymer (FRP / PE) material, wherein the graft copolymer (FRP / PE) material is the fiber-reinforced FRP / PE plastic alloy material.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a method for recycling and processing FRP waste. Background technique [0002] Over the years, FRP has developed rapidly in my country and has been used in various industries. With the continuous growth of the FRP industry, the scraps produced in the production process and the discarded old FRP waste have also increased sharply, forming serious pollution to the air environment and the ground surface, endangering people's lives and health, and destroying and affecting cities. Civilized, these problems have become thorny issues in the development of the FRP industry. Reusing FRP waste as a resource has become a major problem in today's society and the FRP industry. [0003] At present, most of the waste of glass fiber reinforced plastics is treated as domestic waste landfill, and some are burned, pyrolyzed or crushed as fillers, etc. This kind of treatment...
