Problems solved by technology

[0002] At present, most of the threaded joints on the liquid pipeline are butt-sealed with raw material tape. Although the raw material tape has good corrosion resistance, its mechanical properties are extremely poor. The liquid pipeline is easily vibrated by the impact of water flow, especially the valve interface. The place is greatly impacted by water hammer and vibrates. Here, the traditional raw material tape is used for sealing. The raw material tape is easily broken by the friction of the interface gap, resulting in seal failure and water leakage.

Abstract

The invention discloses a butt joint adhesive raw material for a pipeline threaded joint. The butt joint adhesive raw material for the pipeline threaded joint is prepared from the following raw materials in parts by weight: 40-60 parts of silicone rubber particles, 20-30 parts of nitrile rubber particles, 15-20 parts of white phosphorus powder, 5-9 parts of aluminum powder, 50-90 parts of an acidic silica gel and 5-10 parts of a dispersant. The raw material has the beneficial effects that the butt joint adhesive raw material is high in metal attachment and vibrating and friction resistance, can quickly complete sealing and can be operated with water.

Description

technical field [0001] The invention relates to an adhesive, in particular to a butt joint adhesive raw material for pipe threaded joints. Background technique [0002] At present, most of the threaded joints on the liquid pipeline are butt-sealed with raw material tape. Although the raw material tape has good corrosion resistance, its mechanical properties are extremely poor. The liquid pipeline is easily vibrated by the impact of water flow, especially the valve interface. The place is greatly impacted by water hammer and vibrates. Here, the traditional raw material tape is used for sealing. The raw material tape is easily broken by the friction of the interface gap, resulting in seal failure and water leakage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a raw material for butt joint adhesive of pipe threaded joints. [0004] In order to solve the above-mentioned technical problems, the technical solution ...
