The PE pipe comprises a first plastic pipe located outside and a second plastic pipe located inside; the first plastic pipe comprises PE, a filling agent, a flame retardant, a coloring agent, an anti-static agent and a dispersant; the filling agent is diatomite, the flame retardant is a bromine flame retardant, the coloring agent is titanium dioxide, the anti-static agent is sodium dodecyl benzene sulfonate, and the dispersant is ethylene distearamide; the second plastic pipe comprises PE, a flame retardant, a coloring agent, a coupling agent and a reinforcing agent; the flame retardant is antimony pentoxide, the coloring agent is zinc oxide powder, the coupling agent is vinyltriethoxysilane, and the reinforcingagent is carbon black.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to an easy-coloring flame-retardant polyethylene pipe. Background technique [0002] PE is polyethylene plastic, the most basic kind of plastic, plastic bags, plastic wrap, etc. are all PE. At present, in China's municipal pipe market, plastic pipes are developing steadily, and PE pipes, PP-R pipes, and UPVC pipes all occupy a place, among which the strong development momentum of PE pipes is the most eye-catching. However, the PE pipes used in the prior art still have great deficiencies, such as high production cost, poor flame retardancy, and are extremely easy to be burned, resulting in a safety crisis. [0003] The PE pipes used in the prior art still have great deficiencies, such as high production cost, poor flame retardancy, extremely easy to be burned, resulting in a safety crisis, and poor colorability. Contents of the invention [0004] The purpose of the present inventi...
