Abstract
The invention discloses a heat-resistant stable PE water supply pipe comprising the following raw materials in parts by weight: 96-100 of high density polyethylene, 5-7 of hydrotalcite powder, 1-2 of glass fibers, 1-3 of barium sulfate powder, 1-3 of bisphenol A phosphite, 1-2 of barium naphthenate, 0.1-0.2 of urea-based triethoxypropylsilane, 1-2 of acetyl trioctyl citrate, 0.1-0.2 of zinc oxide, and 3-4 of a modifying assistant. The produced PE water supply pipe has quite good heat stable performance, can be quite well applied to various high hot areas, and is safe and reliable; and the added modifying assistant increases the interfacial bonding strength of the raw materials with the PE polymer, can form good physical entanglement, and can improve flexibility, compression resistance and other performance of the finished product.
Description
Technical field
The present invention relates generally to a kind of PE water service pipe, belongs to the tubing field.
Background technology
The PE(polyethylene) material, due to characteristics such as its intensity are high, high temperature resistant, anticorrosive, nontoxic, is widely used in water service pipe and manufactures field.Because it can not get rusty, so, be the desirable tubing that substitutes common iron water service pipe; Polyethylene is the inertialess material, except a small amount of strong oxidizer, can corrode by the medicine of anti-the number of chemical, and is difficult for breed bacteria.Well-known steel pipe, cast iron pipe are not only by the reason that plastics tubing replaced because plastic pipe is low than its water delivery energy consumption, the life energy consumption is low, lightweight, flow resistance is little, simple installation is rapid, cost is low, the life-span is long, have heat insulation function etc., go back corrosion-resistant because of plastics tubing, be difficult for growing the performance such as microorganism and be better than steel pipe and cast iron pipe.
Expansion gradually along with urban construction, the PE water service pipe also will be used to rugged environment more, the chemical substance burn into persistence high pressure such as the high low temperature of persistence, soda acid etc., therefore further improve the performance of conventional P E water service pipe, improve product quality, for China's modernization construction, good promoter action is arranged.
