Memory rubber with high cohesiveness as well as preparation method and application thereof

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...

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 better elasticity and can prevent the gas pipeline from shrinking to a certain extent, but the memory rubber has poor viscosity, and the rubber cover needs to be fixed on the pipe with auxiliary tools such as tape, and the tape is easy to Aging causes the rubber to separate from the gas pipeline, resulting in poor fixing effect of the rubber, and the gas pipeline is easily affected by the environment; therefore, rubber with better adhesion is required to be set on the gas pipeline to realize the protection of the gas pipeline
