Abstract
The invention discloses a light-resisting and oxygen-resisting plastic piping material, which comprises three layers, wherein both the outer layer and the inner layer are polypropylene random copolymer layers; and the middle layer is a light-resisting and oxygen-resisting layer. The light-resisting and oxygen-resisting plastic piping material is characterized in that: the light-resisting and oxygen-resisting layer comprises the following components in part by weight: 100 to 200 parts of polypropylene random copolymer resin, 5 to 20 parts of light-resisting material, 10 to 50 parts of oxygen-resisting material, 0.5 to 3 parts of color masterbatch, 0.1 to 3 parts of antioxidant and 0.1 to 2 parts of ultraviolet light stabilizer. A light-resisting and oxygen-resisting effect is achieved by adding the light-resisting and oxygen-resisting layer positioned in the middle of a pipe wall, so the application range of the piping material is widened, and the service life of the piping material is prolonged.
