Abstract
The invention relates to a formula of a 70 DEG C cable insulation sheath. The formula comprises the following components in parts by weight: 49-51 parts of resin, 16-18 parts of calcium powder, 4-8 parts of kaolin, 7.5-8.5 parts of p-phenyl, 11-13 parts of o-phenyl, 8.5-9.5 parts of liquid wax, 2.3-2.7 parts of stabilizing agent, 0.7-0.85 part of hard barium, 0.2-0.4 part of stearic acid, 0.2-0.4 part of hard wax and 0.45-0.55 part of plasticizing agent. The formula has the advantages of reasonableness in material matching, convenience in preparation, low preparation cost and the like, can improve the insulating property of a cable and prolong the service life of the sheath, and ensures the normal use of equipment or communications.
Description
Technical field
The present invention relates to cables manufacturing technical field, specifically a kind of formula of 70 DEG C of cable insulation jackets.
Background technology
It is comparatively general that cable is applied in daily life, cable has power cable, control cables, compensating cable, shielding cable, high-temperature cable, computer cable, signal cable, concentric cable, flame resistant cable, shipboard cable, aluminium alloy cable etc., cable relies on the sheath of himself to play a protective role to inner conductor, and traditional cable sheath is prepared burden unreasonable due to self, cause the sheath tensile strength manufacturing lower, poor toughness, in actual use procedure, can or pull and draw cable bend unavoidably, so very easily cause breaking of sheath, the cable conductor that cannot continue being wrapped in sheath inside plays a protective role, insulating property are poor, work-ing life is shorter.
Summary of the invention
It is that a kind of material adapted reasonably, is conveniently manufactured, low cost of manufacture that technical problem to be solved by this invention is to provide, and can improve insulating performance of cable and extend the sheath formula in work-ing life, i.e. a kind of formula of 70 DEG C of cable insulation jackets.
Technical problem to be solved by this invention realizes by the following technical solutions:
A formula for 70 DEG C of cable insulation jackets, this formula comprises resin, calcium powder, kaolin, to benzene, adjacent benzene, liquid wax, stablizer, hard barium, Stearic Acid, hard wax and fluidizer, 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.
Kaolin: have that whiteness is high, matter is soft, easy dispersion suspension in water, good plasticity-and high cohesiveness, good electrical insulation capability; There is good antiacid dissolubility, very low cation exchange capacity, the physico-chemical property such as resistivity against fire preferably, therefore kaolin has become tens necessary raw mineral materialss of industry such as papermaking, pottery, rubber, chemical industry, coating, medicine and national defence, can strengthen the insulating property of cable sheath.
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.
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 have material adapted rationally, convenient manufacture and the advantage such as low cost of manufacture, can improve insulating performance of cable, and extend sheath work-ing life, guaranteed the normal use of equipment or communication.
