Abstract

The invention discloses a polyethylene seven-hole cinquefoil pipe and a preparation method thereof. The polyethylene seven-hole cinquefoil pipe is composed of the following components by weight: 60-80 parts of low density polyethylene, 4-8 parts of alkali-free glass fiber, 1-10 parts of filling masterbatch, 0.1-0.4 part of an antioxidant, and 0.1-0.5 part of a compatilizer. The filling masterbatch is prepared from the following components by weight: 50-70 parts of high density polyethylene, 5-15 parts of alkali-free glass fiber, 0.1-0.4 part of an antioxidant, 5-10 parts of calcium carbonate, 5-10 parts of kaolin, 0.1-0.5 part of a coupling agent, 0.1-0.5 part of a compatilizer, and 0-1 part of a toughening agent. The polyethylene seven-hole cinquefoil pipe provided by the invention has the advantages of excellent rigidity and toughness, environmental corrosion resistance, oxidation resistance, and ageing resistance. The polyethylene seven-hole cinquefoil pipe provided by the invention has smooth inner wall and small friction coefficient, is convenient for optical cables or coaxial cables to pass through, cannot damage optical cables or coaxial cables, and is suitable for installation and use of communication lines in telecommunications, electric power and railway.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyethylene (PE) plum blossom tube with seven holes and a preparation method thereof. Background technique [0002] Plum blossom tube is a plum blossom-shaped communication tube, which is suitable for the insertion of many cables such as optical cables, cables, and coaxial cables, and is widely used in telecommunications, radio and television, railways, military and other communication power. With the increasing demand for plum-blossom pipes, plum-blossom pipe manufacturers must control production costs and improve product quality as the top priority in order to stabilize or even expand their market share. [0003] The plum blossom tube adopts a porous integrated structure, which has good rigidity and uniform force. The friction coefficient of the inner wall of the product is small, the cable threading is light and fast, and the construction is simple and easy. Wit...
