Abstract

The invention provides a water feeding pipe and a preparation method thereof and relates to the technical field of plastic pipes. The water feeding pipe comprises, by weight, metallocene linear low density polyethylene, chromium carbonate, fumed silica, nano-active calcium carbonate, metallocene linear low density polyethylene wax, phthalate, gamma-aminopropyltriethoxysilane, rose essential oil, dibutyltin dilaurate, a modifying aid, aluminum hydroxy distearate, hollow glass microbeads, aluminum hydroxide, nano zirconium carbide, aluminum silicate, glass fibers, a thermal stabilizer, a photo-stabilizer, an antioxidant, a compatilizer, and a plasticizer. The preparation method includes the steps of: 1) weighing raw materials; 2) performing granulation; 3) performing mixing, kneading, cooling, extrusion and shaping. The water feeding pipe has high mechanical strength, good flame retarding property, good toughness and good anti-aging performance.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and in particular relates to a water supply pipe and a preparation method thereof. Background technique [0002] PE material is widely used in the field of water supply pipe manufacturing due to its high strength, high temperature resistance, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe to replace ordinary iron water supply pipes. With the gradual expansion of urban construction, water supply pipes will also be used in harsher environments, such as continuous high and low temperature, acid and alkali and other chemical corrosion, and continuous high pressure. In addition, the existing water supply pipes have poor flame retardancy, which seriously affects the safe use of the water supply system. [0003] Therefore, it is necessary to further improve the mechanical strength, flame retardancy, toughness and aging resistance of the water supply pipe to...
