Sheath tube for preventing rat and termite biting, and production method thereof

Abstract

The invention provides a sheath tube for preventing rat and termite biting. The sheath tube comprises, by weight, 100 parts of resin, 0.5-8 parts of a stabilizer, 1-15 parts of a rat-proof tougheningagent, 0.5-5 parts of an anti-ant lubricant, 0.5-10 parts of an anti-ant additive, 0.5-10 parts of an anti-mouse additive and 0.5-5 parts of a paint; the resin is PVC resin; the stabilizer is at leastone of a calcium-zinc stabilizer, a rare earth stabilizer and an organotin stabilizer; the anti-mouse toughening agent is an ethylene-vinyl acetate copolymer; the anti-ant lubricant is at least one of orange essential oil and camphor oil; the anti-ant additive is at least one of chili powder, garlic powder, prickly heat powder, borax, mint leaves and white resin; and the anti-mouse additive is atleast one of tulip, incense and camphor balls. The invention also provides a production method of the tube. The service life of the sheath tube is prolonged, so the hidden safety troubles of a gas pipe are reduced, the service life of an optical fiber is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of pipe materials, and in particular relates to a sheath pipe material for preventing damage by mice and termites and a preparation method thereof. Background technique [0002] At present, the consumption of plastic pipes in my country ranks first in the world, and a large number of plastic gas pipes replace steel pipes. Although plastic gas pipes are easy to install and transport, resistant to corrosion and aging, and have a long service life, the material is softer than steel pipes. If they are bitten by mice or termites, they will be damaged There are serious security risks. [0003] At the same time, various sensing optical fibers are applied to smart pipelines, which can transmit and detect the operation status of the pipeline through the conversion device. The sensing optical fiber is generally installed with a sheath tube. If the sheath tube is bitten by mice or termites, the optical fiber is buried deep underg...

[0002] At present, the consumption of plastic pipes in my country ranks first in the world, and a large number of plastic gas pipes replace steel pipes. Although plastic gas pipes are easy to install and transport, resistant to corrosion and aging, and have a long service life, the material is softer than steel pipes. If they are bitten by mice or termites, they will be damaged. There are serious security risks

[0003] At the same time, various sensing optical fibers are applied to smart pipelines, which can transmit and detect the operation status of the pipeline through the conversion device. The sensing optical fiber is generally equipped with a sheath tube. If the sheath tube is bitten by mice or termites, the optical fiber is buried deep underground. , the replacement is troublesome and the cost is relatively high
