Description
Technical field
The present invention relates to cable rapidoprint field, be specifically related to a kind of high-strength transparence sheath material of cable external application.
Background technology
Electric wire is the carrier that electric power is carried and information is transmitted, and is widely used in industry, civilian electricity consumption facility. Electric wire is used in different environment or occasion, requires differently, and this has just proposed higher requirement to the cable cover(ing) being coated on outside cable. The major function of cable cover(ing) is mechanically to suffer to make it to lose the various situations of transfer function with the cable of electric upper protection transmission use is unlikely. Cable cover(ing) must be installing, continuing completes this defencive function with the whole service life of cable is interim. Within the service life phase of cable, sheath must protect cable core not make moist and other pollute, and the degree of protection will make the loop performance in cable core keep normal, once too much moisture or other pollutants enter cable core, transmission performance will severe exacerbation. This just requires cable cover(ing) to possess higher mechanical strength, inner toughness, in case produce cracking or damaged under rugged environment, causes cable to transmit not normal or generation potential safety hazard.
Cable sheath material of the prior art mostly is opaque sheath, although it is widely used, also exists and is not easy to damaged eliminating, parallel wire and the connector that carries out fault of electric wire shielding and the shortcoming such as circuit tracing is comparatively difficult; Existing transparent sheath mostly is simple and easy flexible plastic, and intensity is lower, can not meet the protection demand to cable.
Summary of the invention
For prior art deficiency, the invention provides a kind of high-strength transparence sheath material of cable external application.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of high-strength transparence cable sheath material, comprise the raw material of following mass fraction: 50 ~ 80 parts of the ethylene-vinyl acetate copolymers that vinyl acetate content is 18%～20%, PETG-1, 20 ~ 40 parts of 4-cyclohexanedimethanoester esters, plasticizer cyclohexane alkane 1, 1 ~ 2 part of 2-dioctyl phthalate two (2-propyl group heptan) ester, 20 ~ 50 parts of nitrile silicone rubbers, 5 ~ 12 parts of nano silicons, 3 ~ 8 parts, calcium carbonate, 2 ~ 6 parts of styrene copolymers, 0.1 ~ 0.2 part of perfluoro butyl potassium sulfonate, 5 ~ 10 parts of paraffin oils, reinforcing agent DH-30.2 ~ 0.6 part.
Further, described a kind of high-strength transparence cable sheath material, comprise the raw material of following mass fraction: 65 parts of ethylene-vinyl acetate copolymers, PETG-1 that vinyl acetate content is 18%～20%, 30 parts of 4-cyclohexanedimethanoester esters, plasticizer cyclohexane alkane 1,1 part of ester of 2-dioctyl phthalate two (2-propyl group heptan), 35 parts of nitrile silicone rubbers, 8 parts of nano silicons, 6 parts, calcium carbonate, 4 parts of styrene copolymers, 0.2 part of perfluoro butyl potassium sulfonate, 8 parts of paraffin oils, reinforcing agent DH-30.4 part.
Further, described a kind of high-strength transparence cable sheath material, its preparation method comprises the following steps:
1) be on the waiting list raw material according to described mass fraction;
2) raw material of being on the waiting list is fully mixed;
3) step 2 gained is mixed to material and be placed in double screw extruder, mixing at 160 ~ 190 DEG C, granulation, make finished product.
In the present invention, adopt the transparency good composite matrix as sheath material of ethylene-vinyl acetate copolymer, PETG-1,4-CHDM ester and nitrile silicone rubber, compound has good transparency and intensity preferably; The interpolation of raw material calcium carbonate can reduce the preparation cost of sheath material, improves the creep properties of goods, improves heat distortion temperature and the dimensional stability of goods; Raw material nano silica is for improving wearability, fold resistance, tensile strength, the ageing resistace of material system, and then intensity and the percentage elongation of raising sheath material, obtains wearability and the surperficial good cable cover(ing) of fineness; Benzene feedstock ethylene-dien terpolymer can make the impact strength of its goods improve, and can also improve the cold resistance of goods simultaneously; Reinforcing agent can increase the combination between the inorganic material such as calcium carbonate, nano silicon or filler and ethylene-vinyl acetate copolymer, PETG-1,4-CHDM ester and nitrile silicone rubber, and then reaches good mechanical strength.
To sum up, the beneficial effect that a kind of high-strength transparence cable sheath material provided by the invention possesses is: sheath material of the present invention has the good transparency, when use, be easy to electric wire shielding breakage to carry out the eliminating of fault, what make that parallel wire and connector and circuit tracing become is more simple to operation, especially more accurate, be not easy to application under the conditions such as dismounting maintenance and can bring larger convenience; Sheath material of the present invention has higher mechanical strength and combination property when having good transparency, have good stability, and embrittlement cracking occurs can not process under cold climate and install time, and wearability is better.
