Anti-aging polyethylene pipe

Abstract

The invention discloses an anti-aging polyethylene pipe which is prepared from, by weight, 70-78 parts of polyethylene resin, 5-12 parts of polyurethane rubber, 5-12 parts of nonylphenol polyoxyethylene ether, 3-5 parts of silicon dioxide, 2-4 parts of triphenyl phosphate, 2-6 parts of dimethyl phthalate, 3-7 parts of aluminum nitride, 2-6 parts of benzoic acid, 3-5 parts of dibasic lead phosphate, 3-7 parts of octyl stannum mercaptide and 6-9 parts of thermal-plastic polyurethane. The anti-aging polyethylene pipe is easy to manufacture, better in notch impact strength, tensile strength, bending strength, bending modulus and breaking elongation and longer in service life, and the anti-aging performance is better. Raw materials of the pipe are reasonably arranged, so that the overall strength and hardness of the material meet requirements, the anti-aging performance of the pipe is improved, and the pipe can better adapt to underground severe environments and is long in service life.

Description

technical field [0001] The invention specifically relates to an anti-aging polyethylene pipe. Background technique [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. Chemical building materials have made great progress and developed rapidly in our country, especially the widespread use of new environmentally friendly plastic pipes, which has set off a revolution to replace traditional building materials. Plastic pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages such as small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipe networks in the new century. [0003] Compared with traditional cast iron pi...
