Problems solved by technology

[0003] Existing gas pipes are generally made of steel pipes, and temperature changes will cause expansion or contraction of the pipes. If the weather is cold, the gas pipes will shrink. At this time, the surface of the gas pipes is relatively brittle, and it is prone to rupture, resulting in gas leakage. The gas pipeline needs to be replaced; for this reason, the gas company usually puts a protective sleeve on the gas pipeline to protect the gas pipeline
[0004] The existing protective cover is generally memory rubber, which has

Abstract

The invention discloses memory rubber with high cohesiveness as well as a preparation method and application of the memory rubber. The memory rubber is prepared from the following raw materials in parts by weight: 20-40 parts of rubber; 10 to 20 parts of polycarbonate; 1-2 parts of an antioxidant; 5 to 8 parts of a tackifier; 1-5 parts of stearic acid; and 1-5 parts of sulfur. The memory rubber has the effect of improving the cohesiveness of the memory rubber.

Description

technical field [0001] The present application relates to the field of rubber, in particular to a memory rubber with high cohesiveness and its preparation method and application. Background technique [0002] The gas pipeline is connected by connecting pipes and valves to form a fluid device for transporting gas, liquid or solid particles. The daily gas supply to residents’ lives is realized through gas pipeline transportation. The gas supply system in cities and towns is usually carried out by laying various gas pipelines. Gas delivery to form a complete gas delivery system. [0003] Existing gas pipes are generally made of steel pipes, and temperature changes will cause expansion or contraction of the pipes. If the weather is cold, the gas pipes will shrink. At this time, the surface of the gas pipes is relatively brittle, and it is prone to rupture, resulting in gas leakage. The gas pipeline needs to be replaced; for this reason, the gas company usually puts a protective...
