Abstract
The invention relates to a formula of a 70 DEG C cable sheath, which comprises the following ingredients in parts by weight: 48-52 parts of resin, 20-24 parts of calcium powder, 8.5-9.3 parts of p-phenylene, 11.5-12.5 parts of phthalate, 8.8-9.3 parts of liquid wax, 1.7-2.2 parts of stabilizer, 0.6-0.9 part of hard barium, 0.4-0.6 part of a composite additive and 0.4-0.6 part of a plasticizer. The 70 DEG C cable sheath has the advantages of reasonable material collocation and low production cost, the tensile strength of the sheath is improved, the tenacity of the sheath is improved, the sheath damage caused by bending and pulling in the actual use process is effectively prevented and the service life of the sheath is prolonged.
Description
Technical field
The present invention relates to cables manufacturing technical field, specifically a kind of formula of 70 DEG C of PVC cable sheaths.
Background technology
PVC sheath is a kind of with wrapped with insulation stranded copper wire stranded conductor, the flat cable forming by sheath material pressing by high-tech automatic equipment production line, there is the advantages such as softness, random bending fold, relative thickness is thin, volume is little, connection is simple, convenient disassembly, can select arbitrarily wire number and spacing, make on line more convenient, greatly reduce the volume of product, reduce production cost, enhance productivity, be applicable to being used as in electrical equipment data transmission cable or power transmission.Common specification has the various spacing flexible cable such as 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm.And traditional PVC 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, and work-ing life is shorter.
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 sheath performance and extend the sheath formula in work-ing life, i.e. a kind of formula of 70 DEG C of PVC cable sheaths.
Technical problem to be solved by this invention realizes by the following technical solutions:
A formula for 70 DEG C of PVC cable sheaths, this formula comprises resin, calcium powder, to benzene, adjacent benzene, liquid wax, stablizer, hard barium, composite additive and fluidizer, the parts by weight of each component are as follows:
The shared optimum weight umber of described each component is as follows:
Described composite additive is the mixture of Stearic Acid and hard wax, and the mass ratio of described Stearic Acid and hard wax is 3:2.
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.
Composite additive: adopt Stearic Acid and hard wax to mix, wherein Stearic Acid is the mixture of stearic acid and palmitinic acid, and contain a small amount of oleic acid, micro-have a butter sample smell, the atomic cold water that is dissolved in, be soluble in benzene, toluene, chloroform, tetracol phenixin, dithiocarbonic anhydride, pentyl acetate etc., be also dissolved in ethanol, acetone; Hard wax, claims again synthetic paraffin, has 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 has material adapted rationally and the advantage such as low cost of manufacture, can 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, extend sheath work-ing life.
