High-strength polyethylene tube for communication and preparation method thereof

Abstract

The invention discloses a high-strength polyethylene tube for communication, wherein a component A comprises 100 parts of high-density polyethylene, 0.5-3.0 parts of silane and 0.05-0.15 part of dicumyl peroxide; a component B comprises 100 parts of high-density polyethylene and 0.02-1 part of dibutyltin dilaurate; and an additive component C comprises 0.5-1.5 parts of antioxidant and 0.6-0.8 part of benzophenone ultraviolet absorbent. The formula of the polyethylene tube for communication is improved by a mode of silane cross-linked with polyethylene, the strength of the tube is improved, and the tube has the advantages of rigid texture, better toughness and better environmental resistance.

Description

technical field [0001] The invention relates to the field of communication pipes, in particular to high-density polyethylene communication pipes, and in particular to a high-strength polyethylene communication pipe based on high-density polyethylene modification and a preparation method thereof. Background technique [0002] PE pipes are one of the most commonly used pipes except PVC pipes. PE pipes have superior corrosion resistance, good strength, can withstand a certain strain capacity, and have a long service life. They are light in weight, easy to install, and have good flexibility. Low temperature resistance and other advantages, used in many fields. [0003] However, the commonly used PE pipes also have some defects: relatively low strength, easy to be damaged during laying or use, and poor weather resistance to the environment. In cold regions, the temperature below zero is not suitable for laying construction. At this time, the polyethylene pipe is easy to be britt...

Problems solved by technology

[0003] However, the commonly used PE pipes also have some defects: relatively low strength, easy to be damaged during laying or use, and poor weather resistance to the environment. In cold regions, the temperature below zero is not suitable for laying construction. At this time, the polyethylene pipe is easy to be brittle; in addition, the PE pipe is easy to age and has a low service life

However, there are relatively few high-density polyethylene pipes in our country. Now we hope to improve the strength of polyethylene communication pipes, improve their environmental resistance, and broaden the temperature range of their use environment by doing some modification research on polyethylene.
