Problems solved by technology

If ultrasonic welding is used for high-density polyethylene winding structural wall pipes, good quality welding results will be obtained, but for the current polyethylene, it is not suitable for ultrasonic welding. When ultrasonic welding is performed on some materials, there is a welding time Limitations of longer, higher welding requirements

Abstract

The invention relates to the technical field of polyethylene preparation, in particular to an easy-to-weld high-density polyethylene material. Including main materials, auxiliary materials and auxiliary agents; in parts by weight, the main materials include 65-75 parts of high-density polyethylene, 20-25 parts of low-density polyethylene, 5-8 parts of POE, 3-5 parts of aluminum silicate and 6-9 parts of zinc oxide; auxiliary materials include 10-15 parts of atactic polypropylene, 5-7 parts of PMMA powder, 1-2 parts of sodium aluminum silicate, 3-5 parts of carbon black and 2-3 parts of silicon dioxide; Dose 3‑8 parts. The material can not only reduce the operation difficulty of the current welding process, but also meet the ultrasonic welding process of polyethylene.

Description

technical field [0001] The invention relates to the technical field of polyethylene preparation, in particular to an easy-to-weld high-density polyethylene material. Background technique [0002] High-density polyethylene winding structural wall pipes are rain and sewage drainage pipes that have been widely used at home and abroad. Due to the use of different structural wall designs, this type of pipe has the advantages of saving raw materials, high ring stiffness, long service life, and stable quality. Reliable, convenient connection, good airtightness and other advantages, so it has a strong market potential. [0003] The connection between the polyethylene winding structure wall pipes is usually carried out by welding. The raw materials used in the current polyethylene winding structure wall pipes will be heated unevenly during the welding process and the welding effect is not good. The result is There will be quality problems with the soldered ports. At the same time, ...
