Novel modified composite plastic

Abstract

The invention discloses novel modified composite plastic which is prepared from polypropylene, thermoplastic styrene-butadiene rubber, a silicon powder and aluminum powder mixture, phenolic resin, a bentonite and kaolin mixture, sodium acrylate, bamboo powder, bauxite, aluminum nitride, a dispersing agent, a plasticizer and a heat stabilizer. The novel modified composite plastic is stable in mass and good in mechanical, physical and chemical property. By adding the silicon powder and aluminum powder mixture, the heat resistance of the composite plastic is greatly improved, and the structure is improved; by means of mixing pretreatment of the phenolic resin and the aluminum nitride, plastic ingredients are more uniform; by adding the bentonite and kaolin mixture, the weather resistance of the composite plastic is greatly improved, and the secondary processing performance is improved; during processing and preparation, the polypropylene and the sodium acrylate are mixed and added to a double-screw extruder at first, accordingly, the integration between the polypropylene and other ingredients can be improved, the structural quality of plastic is improved, and the service life of the plastic is prolonged.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a novel modified composite plastic. Background technique [0002] Polypropylene (PP) has good corrosion resistance, rigidity and transparency, and is currently widely used to make packaging containers. However, polypropylene has poor impact resistance, becomes brittle at low temperature, and is easy to age. Moreover, in order to reduce raw material input and production costs, the majority of manufacturers try to make the packaging containers lighter in weight and thinner in wall thickness. , therefore, existing polypropylene-based [0003] The packaging container made of this material is very soft to the touch, and the strength is not high enough. High liquid or semi-liquid materials are easy to overflow and cause harm to the human body. Therefore, it needs to be compounded and modified to solve these problems. Contents of the invention [0004] The purpose of the present ...
