Problems solved by technology

[0002] At present, the commonly used safety helmet is made of glass fiber reinforced plastic material. This kind of safety helmet is made of synthetic resin mixed at high temperature. The chemical odor harmful to the human body is also harmful to the air and pollutes the environment; when the human body wears a safety helmet, the glass fiber contacts the skin, which will also cause some adverse reactions to the human skin; and in the production process, there are The unqualified materials cannot be reused, and all of them are treated as waste products. This process causes a certain waste of resources

Abstract

The invention relates to a novel composite material, and a preparation method and an application thereof. The novel composite material is prepared from polyoxyethylene, polypropylene resin, polyamide resin, poly(ethylenediamineoxalic acid) resin, short cut carbon fibers and graphite, and the sum of weight proportions of above raw materials is 100%. The preparation method comprises the following steps: mixing and uniformly stirring the raw materials, extruding the obtained mixture, and granulating the extruded mixture to prepare a finished product. The composite material can be used for processing safety caps. The material has the advantages of no smell, no generation of toxic or radioactive substances in the production process, environmental protection, and no irritation to skins when being in contact with skins; wastes generated in the production process can be recycled, so wastes are avoided, and resources are saved; and the strength and the lateral rigidity of the produced safety caps reach standard requirements.

Description

technical field [0001] The invention relates to a novel composite material, a manufacturing method and an application. Background technique [0002] At present, the commonly used safety helmet is made of glass fiber reinforced plastic material. This kind of safety helmet is made of synthetic resin mixed at high temperature. The chemical odor harmful to the human body is also harmful to the air and pollutes the environment; when the human body wears a safety helmet, the glass fiber contacts the skin, which will also cause some adverse reactions to the human skin; and in the production process, there are The unqualified materials cannot be reused, and all of them are treated as waste products. This process causes a certain waste of resources. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and provide a new type of composite material and its production method and application. This material has no odor, no p...
