Abstract

The invention relates to an anti-corrosion silicon core pipe, which comprises an inner layer and an outer layer. The outer surface of the outer layer and the inner surface of the inner layer are provided with anti-corrosion protective layers respectively. Each anti-corrosion protective layer comprises 74.5-80wt% of high density polyethylene, 7-15wt% of activated carbon fibers, 6-15wt% of antibacterial microcapsules and 2-3.5wt% of a dispersing agent. The silicon core pipe is provided with the anti-corrosion protective layers which are provided with the antibacterial microcapsules with garlic essential oil or mustard essential oil serving as a core material. The garlic essential oil or mustard essential oil has great antibacterial effects and is capable of effectively inhibiting growth of microorganisms such as mildew to protect the silicon core pipe; further, the garlic essential oil or mustard essential oil has certain irritation, so that probability that small animals bite the pipe can be lowered; in addition, the anti-corrosion protective layers are further provided with magnesium sulfate solution loaded activated carbon fibers with great moisture absorption performance, so thatsurroundings of the silicon core pipe can be kept dry, a growth environment of the microorganisms such as mildew is destroyed, growth of the microorganisms such as mildew is reduced, and the siliconcore pipe is protected from being corroded by the microorganisms.

Description

technical field [0001] The invention relates to the field of silicon core tubes, in particular to a corrosion-resistant silicon core tube. Background technique [0002] Silicon core pipe is a new type of composite pipe with silica gel solid lubricant on the inner wall. It has good toughness, good water resistance, anti-corrosion, long service life, smooth inner pipe wall, small friction coefficient, good sealing performance and low engineering cost. Etc. Because in the communication industry, the inner wall of the protective tube is required to be smooth to reduce the damage of the protective tube to the optical cable when the optical cable passes through the tube, the silicon core tube is widely used in the communication industry. In practical applications, silicon core tubes are often corroded and damaged after being used for a period of time due to environmental reasons, thus affecting the protection of the optical cable inside. Environmental reasons include chemical co...
