Abstract

The invention discloses anti-aging polyethylene composite plastic, and belongs to the technical field of polyethylene processing, solving the problems that pure polyethylene materials with low heat resistance and poor molding shrinkage affect the service life of polyethylene plastic products and cause resource waste. The anti-aging polyethylene composite plastic is characterized by comprising, byweight, 120-150 parts of polyethylene, 50-90 parts of maleic anhydride grafted polypropylene, 5-12 parts of polycarbonate, 15-25 parts of graphite powder, 15-30 parts of calcium aluminum borosilicate,10-20 parts of pyrophyllite, 2-8 parts of trioctyl trimellitate, 10-18 parts of antistatic agents, 10-12 parts of light stabilizers, 10-20 parts of dibasic lead phosphite, and 10-15 parts of monoammonium phosphate. The prepared polyethylene plastic has high flame retardancy and excellent mechanical property and avoids aging of polyethylene products, thereby having a broad market prospect.

Description

technical field [0001] The invention relates to the technical field of polyethylene processing, in particular to an anti-aging polyethylene composite plastic and a preparation method thereof. Background technique [0002] With the acceleration of people's life rhythm and the development of convenience and sanitation in our life, people's requirements for environmental sanitation are getting higher and higher. In order to improve the rhythm of life, polyethylene composite plastic is a non-toxic, harmless and good It is a thermoplastic material with electrical insulation performance and corrosion resistance. Polyethylene plastic has good strength and can play the role of cold resistance and flame retardancy. At present, polyethylene plastic is widely used in construction, transportation and wire and cable industries. Pure polyethylene plastic The material has the defects of poor heat resistance and poor molding shrinkage, which in turn affects the service life of polyethylene ...
