Abstract
The invention relates to a formula for a 90DEG C cable sheath. The sheath comprises the following components in parts by weight: 49.5-50.5 parts of resin, 19-22 parts of calcium powder, 5.5-6.5 parts of p-benzene, 6-10 parts of o-benzene, 8.5-9.5 parts of liquid paraffin, 1.7-2.1 parts of stabilizer, 0.77-0.82 part of barium stearate, 0.4-0.6 part of stearic acid, 0.2-0.4 part of hard wax, 5.5-7 parts of meta-benzene, and 0.65-0.75 part of plasticizer. The sheath has the advantages of being reasonable for matching of materials, low in manufacturing cost and the like, the tensile strength and toughness of the sheath can be improved, the sheath can be effectively prevented from being damaged due to bending and tearing in the practical usage process of the sheath, and the service life of the sheath can be prolonged.
Description
Technical field
The present invention relates to cables manufacturing technical field, specifically a kind of formula of 90 ℃ of cable sheaths.
Background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires; mutually insulated between every group of wire; and be often twisted into round Yi Gen center; whole outside is surrounded by the tectum of high-insulation; this tectum is cable sheath, plays the effect of insulation and protection inner conductor.And 90 ℃ of traditional cable sheaths are prepared burden unreasonable due to self; the mechanical property that causes the sheath manufacturing as tensile strength and toughness relatively low; in the process using; as the transportation of cable, while setting up, workmen need to draw, bending cable, makes sometimes the sheath of cable occur that cut even breaks; in the working process of cable after this; cable sheath declines to the provide protection of cable inner conductor, the work-ing life that can reduce cable, and easily there is potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of material adapted reasonably, low cost of manufacture, can improve the jacket formula of sheath tensile strength and toughness, i.e. a kind of formula of 90 ℃ of cable sheaths.
Technical problem to be solved by this invention realizes by the following technical solutions:
A formula for 90 ℃ of cable sheaths, this formula comprises resin, calcium powder, to benzene, adjacent benzene, liquid wax, stablizer, hard barium, Stearic Acid, hard wax, benzene and fluidizer partially, the parts by weight of each component are as follows:
The shared optimum weight umber of described each component is as follows:
The performance of part component and effect are as follows:
Resin: as the main component of cable sheath, the mixture being made up of Multiple components, is generally unformed solid, surface is micro-glossy, and matter is hard and crisp, and minority is semi-solid.
Calcium powder: be commonly called as: Wingdale, stone flour, it is a kind of compound, chemical formula is CaCO3, be alkalescence, substantially water insoluble, be dissolved in acid, add after calcium powder, calcium powder is usage quantity one of weighting agent the most greatly in rubber industry, and calcium powder is filled among rubber in a large number, can increase the volume of its goods, and save expensive natural rubber, thus greatly reducing costs, calcium powder is inserted in rubber, can obtain tensile strength, tear strength and the wear resistance higher than gum sulfide, thereby improve the performance of sheath after moulding.
Liquid wax: can each component is better glued together, increase the plasticity-of mixture after mixing, guarantee that sheath can extrude smoothly.
Stablizer: the stability that can increase solution, colloid, solid, mixture, its reaction of can slowing down, keep chemical equilibrium, reduce surface tension, prevent the effects such as light, thermolysis or oxygenolysis, thereby can prevent that cable sheath from the process of reality use, aging phenomenon occurring, and extends the work-ing life of sheath.
Stearic Acid: be the mixture of stearic acid and palmitinic acid, and contain a small amount of oleic acid, micro-have a butter sample smell, and the atomic cold water that is dissolved in, is soluble in benzene, toluene, chloroform, tetracol phenixin, dithiocarbonic anhydride, pentyl acetate etc., is also dissolved in ethanol, acetone.
Hard wax: claim again synthetic paraffin, there is good crush resistance, good insulativity, strong water resisting property.After Stearic Acid and hard wax mixing, can increase the insulating property of sheath like this, improve the tensile strength of sheath, improve the toughness of sheath, can be in the use procedure of sheath reality, effectively avoid bending, pull and draw the destruction that sheath is caused.
Benzene partially: as softening agent, there is good thermotolerance, low volatility, oil-proofness and workability, be widely used as the softening agent of the heat-resisting softening agent of PVC, anti-solvent crosslinkable vinyl chloride resin, can make the snappiness of sheath strengthen, easily processing.
Fluidizer: can increase the toughness of sheath, facilitate the processing of extruding of sheath.
The invention has the beneficial effects as follows: the present invention has material adapted rationally and the advantage such as low cost of manufacture, can improve sheath tensile strength and toughness, can be in the use procedure of sheath reality, effectively avoid bending, pull and draw the destruction that sheath is caused, extend the work-ing life of sheath.
