Embodiment Construction

[0012] A rodent-proof water-blocking polyvinyl chloride cable material for buried ground, made of the following raw materials in weight (kg): polyvinyl chloride 54, polystyrene 26, high-substituted cyanoethyl cellulose 22, calcium rosinate 9 , tribasic lead sulfate 3, diethylene glycol dibenzoate 13, α, ω-dihydroxypolydimethylsiloxane 6, sodium fluoroacetate 4, hydrophobic fumed silica 8, quartz powder 12, ortho Di-sec-octyl phthalate 11, oxidized polypropylene wax 6, feldspar 16, zinc cyanurate 2, glyceryl tristearate 6, chloropicrin 5, zirconium acetate 4.5, diopside 11.

[0013] A method for preparing a rodent-proof water-blocking type buried polyvinyl chloride cable material, comprising the following steps:

[0014] (1) Mix quartz powder, feldspar, and diopside evenly, pulverize, sieve, then heat and melt to form a molten liquid, stir well, put it into clean water for water quenching, dry, pulverize, sieve, 18000r / min high-speed ball milling for 0.5h, sieving, and then u...

Abstract

The invention discloses a rat-proof termite-proof water-resistant buried polyvinyl chloride cable material and a preparation method thereof. The cable material is prepared from, by weight, 46-61 parts of polyvinyl chloride, 19-31 parts of polystyrene, 14-26 parts of highly cyanoethylated cellulose, 6-12 parts of calcium rosinate, 2-4 parts of lead sulfate tribasic, 10-15 parts of diethylene glycol dibenzoate, 4-8 parts of alpha, omega-dyhydroxy polydimethylsiloxane, 3-6 parts of sodium fluoroacetate, 5-10 parts of hydrophobic fumed silica, 10-15 parts of quartz powder, 8-13 parts of di-sec-octyl phthalate phthalate, zirconium acetate, diethylene glycol dibenzoate and the like. Water absorptivity of the cable material can be remarkably reduced, and water resistance of the cable material is improved; due to addition of raw materials such as the sodium fluoroacetate and trichloronitromethane, cables made from the cable material can be effectively protected from being gnawed by rats or damaged by termites.

Description

technical field [0001] The invention relates to a rodent-proof and water-blocking buried polyvinyl chloride cable material and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] Polyvinyl chloride (PVC) is a polymeric material (or resin) composed of the molecular formula CH 2 = CHCl monomer vinyl chloride (VCM) stacked multiple times. PVC is widely used in the wire and cable industry because of its good physical, chemical, electrical, and flame-retardant properties, as well as its low price. With the rapid development of the cable industry, there are higher and higher requirements for the performance of PVC cables. However, the rodent-proof performance and water-blocking performance of existing PVC cable materials are more and more unable to meet the requirements of the market. Contents of the invention [0003] The object of the present invention is to provide a rodent-proof water-blocking type buried polyvinyl chlo...
