Problems solved by technology

[0007] In order to solve the problem of adding anti-termite agents to pipe fittings in the prior art, the processing is difficult and the anti-termite agents are easy to decompose. Adding chemical agents directly to the environment will pollute the soil environment, and the agents will be diluted quickly in the soil. Various problems of short time limit; physical prevention is mainly to make high hardness material into a sheath, and then put it on the surface of the protected object, but the sheath is difficult to process and expensive, and the sheath can only be used on the surface of regular objects , it is completely inapplicable to special-shaped parts such as flanges and valves in the pipeline; the invention provides a termite-proof adhesive, adhesive tape and preparation method for polyethylene pipelines

Abstract

The invention provides a termite-resistant adhesive used for a polyethylene pipeline, an adhesive tape and a preparation of the adhesive tape. The termite-resistant adhesive comprises the following components by mass percent: 5-10% of thermoplastic elastomer, 15-25% of amorphous state alpha-olefin copolymer, 15-25% of middle-molecular polyisobutene, 10-15% of tackifying resin, 30-45% of inorganic enhanced powder, 1-2% of an antioxygen, 1-2% of black color master batch and 1-2% of a termite-resistant agent. The adhesive tape containing the termite-resistant adhesive is excellent in termite-resistant effect, slow in pesticide effect release, not easy to degrade, small in impact on environment, durable in pesticide effect and environmentally friendly, also has good adhesive sealing properties, can realize long-acting sealing protection performance in the process of protecting the pipeline to prevent insects, can achieve good termite-resistant effect so long as the adhesive tape is wound and coated on the surface of a protected object when being used and can be widely applied to termite resistance of a PE gas pipeline and various electric wires.

Description

technical field [0001] The invention belongs to the field of termite prevention, and in particular relates to an anti-termite adhesive for polyethylene pipes, an applied adhesive tape and a preparation method thereof, which are applied to the protection against termites of buried polyethylene gas pipes in coastal cities, and can also be used for other buried facilities Excellent termite protection, such as wires and cables, urban buried heating pipes and other facilities. Background technique [0002] With the continuous development of science and technology, PE pipelines have become the main carrier of urban medium-pressure natural gas transmission. However, because the hardness of the PE pipe is not very high, and the temperature of the gas pipeline is higher than that of the surrounding soil (especially in autumn and winter), the PE pipe is particularly easy to gather termites, then bite the pipe, and then build a nest in the pipe, resulting in A natural gas leakage acci...
