Manufacturing method of corrosion-resistant high-flame-retardant silicon core pipe

Abstract

The invention discloses a corrosion-resistant high-flame-retardant silicon core pipe which is prepared from, by weight, 230-320 parts of n-paraffin hydrocarbon, 195-225 parts of high-density polyethylene, 35-45 parts of dodecene, 135-145 parts of methyl hydrogen silicone oil, 25-30 parts of hydroxy stearic acid, 75-85 parts of polyolefin resin, 10-12 parts of color master batches, 6-8 parts of graphene, 3-5 parts of sodium-based bentonite, 2-4 parts of polyvinyl alcohol, 1-2 parts of zinc naphthenate, 2-4 parts of nano-boride, 3-4 parts of polyurethane, 1-2 parts of polyacrylic acid, 3-5 partsof triethyl phosphate, 2-3 parts of chlorinated paraffin, 1-2 parts of antioxidants, 5-7 parts of glycerol and 7-9 parts of deionized water. By the aid of the formula, the corrosion-resistant high-flame-retardant silicon core pipe has high wear resistance, high flame resistance and high reliability, overall consistency is improved, and the problem of delaminating is avoided. In addition, variousreactants with different functions are added, so that reaction is sufficient, various composition effects of the pipe are maximally achieved, and finally, the pipe is quite high in overall performance.

Description

technical field [0001] The invention relates to a production technology of a silicon core tube, in particular to a production method of a corrosion-resistant and highly flame-retardant silicon core tube. Background technique [0002] Silicon core tube is a new type of composite tube with silica gel solid lubricant on the inner wall. It has good sealing performance, chemical corrosion resistance and low engineering cost. It is widely used in optical cable communication network systems such as highways and railways. However, the existing The formula of the silicon core tube is unreasonable, so that the mixing degree of the raw materials is not high, the corrosion resistance of the final product is very poor, and the flame retardancy has been difficult to be greatly improved. In addition, the production method is not appropriate, which makes the reliability of the silicon core tube made Low, it is easy to have the problem of layer-by-layer separation, and the production cost of...
