Problems solved by technology

[0003] The weather resistance of polypropylene material itself is poor. As an appearance part, it will obviously turn yellow and discolor under the irradiation of ultraviolet rays, which seriously affects its appearance.
In addition, the flame retardants used in more flame retardant materials on the market are brominated flame retardants, and the addition amount is relatively large.
During the use of brominated flame retardants, bromine will be released, causing the product to turn yellow and discolored, and at the same time cause the surface gloss of the product to decrease, and its waste will cause certain pollution to human beings and the living environment

Abstract

The invention discloses an environmentally-friendly, high fire-resistant and high seawater-resistant polypropylene and belongs to the technical field of high polymer materials. The environmentally-friendly, high fire-resistant and high seawater-resistant polypropylene is characterized by comprising copolypropylene and / or homopolypropylene, one or more fire retardants, one or more ultraviolet absorbers, one or more light stabilizers, one or more antioxidants, one or more copper toxicity-resistant agents and one or more processing auxiliary agents according to a certain weight part ratio. The environmentally-friendly, high fire-resistant and high seawater-resistant polypropylene has excellent mechanical properties and effects of high fire resistance and high seawater resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an environment-friendly polypropylene with high flame retardancy and high weather resistance. Background technique [0002] At present, polypropylene flame-retardant materials are relatively common, but the production of environmentally friendly high-flame-retardant and high-weather-resistant polypropylene materials on this basis has the following problems: [0003] The weather resistance of polypropylene material itself is poor. As an appearance part, it will obviously turn yellow and discolor under the irradiation of ultraviolet rays, which seriously affects its appearance. In addition, the flame retardants used in more flame retardant materials on the market are brominated flame retardants, and the addition amount is relatively large. Brominated flame retardants will release bromine during use, causing the product to turn yellow and discolored, and at t...
