Anti-ultraviolet environmentally-friendly PE pipe material

Abstract

The invention discloses an anti-ultraviolet environmentally-friendly PE pipe material. The anti-ultraviolet environmentally-friendly PE pipe material is characterized by being prepared from the following raw materials in parts by weight: 60 to 85 parts of high-density polyethylene, 1 to 3 parts of color masterbatches, 3 to 7 parts of a light stabilizer and a heat stabilizer, 1 to 2 parts of an anti-ultraviolet agent, 0.5 to 2 parts of a POE toughening agent, 8 to 12 parts of dioctyl phthalate, 4 to 6 parts of cyclohexanone, 3 to 9 parts of coumarone resin, 5 to 9 parts of melamine, 4 to 8 parts of chlorinated paraffin, 3 to 7 parts of methacrylic acid and 3 to 8 parts of titanium dioxide. According to the invention, through addition of a certain proportion of the light stabilizer, the heatstabilizer and the anti-ultraviolet agent into a polyethylene raw material to avoid generation of free radicals, the macromolecular chain of the polyethylene is guaranteed from being affected by ultraviolet energy, infrared high-temperature energy, oxidation, harmful gases released by microorganisms, acceleration of inorganic substances like soil to absorb energy, etc.; thus, the anti-ultravioletenvironmentally-friendly PE pipe material provided by the invention has the function of prolonging the original service life of a polyethylene product, and has the characteristics of environmental friendliness, no damage to the human body, recyclability, high-temperature resistance, insusceptibility to combustion, etc.

Description

technical field [0001] The invention relates to a PE pipe, in particular to an anti-ultraviolet environment-friendly PE pipe. Background technique [0002] With the development of the photovoltaic industry, photovoltaic power generation has been more and more widely used. The installation of photovoltaic equipment will occupy a large area of ​​land. For areas with large water areas, land resources are often scarce, and scarce land resources cannot be used for solar energy equipment. If the installation provides more land, then it is thought of using buoyancy support for the solar energy equipment and installing it on the water surface, then it is thought of using plastic pipes to provide buoyancy, PE pipe welding is easy to install, easy to operate and buoyancy support of the support, PE pipe is made of polyethylene plastic through extrusion molding. Polyethylene has good chemical stability. It can resist acid at room temperature and is not resistant to strong oxidation. For...

[0002] With the development of the photovoltaic industry, photovoltaic power generation has been more and more widely used. The installation of photovoltaic equipment will occupy a large area of ​​land. For areas with large water areas, land resources are often scarce, and scarce land resources cannot be used for solar energy equipment. If the installation provides more land, then it is thought of using buoyancy support for the solar energy equipment and installing it on the water surface, then it is thought of using plastic pipes to provide buoyancy, PE pipe welding is easy to install, easy to operate and buoyancy support of the support, PE pipe is made of polyethylene plastic through extrusion molding. Polyethylene has good chemical stability. It can resist acid at room temperature and is not resistant to strong oxidation. For users of polyethylene pipes used outdoors, due to Under the action of the atmosphere, sunlight and oxygen, the product will age, change color, crack, become brittle or pulverized, and even lose its mechanical properties, so it is not conducive to the long-term normal use of polyethylene material pipes

[0003] In addition, many PE pipes currently on the market are mainly formed of materials such as polyvinyl chloride, styrene, polycarbonate, and polystyrene. On the one hand, these materials contain many harmful chemical components, causing water pollution, and on the other hand, the cost is relatively high , cannot be recycled, and it is difficult to degrade after being discarded, which will cause serious environmental pollution
