Description
Technical field
The invention belongs to field of cables, and in particular to a kind of wear-resistant tensile stretches the preparation method of cable.
Background technique
Wire cable insulating and sheath are commonly called as CABLE MATERIALS with plastics, and which includes a variety of product such as rubber, plastics, nylon
Kind.CABLE MATERIALS manufacturing enterprise is with cable manufacturing enterprise for user, there is the market of CABLE MATERIALS as long as live wire cabling requirements.Electricity
Insulating layer mouth is almost required in addition to the bare wires product such as steel-cored aluminium strand, electromagnetic wire in line cable product.
Cable protective sleeve is the outermost layer of cable, and cable sheath material not only needs excellent physical property, is such as stretched
Intensity, elongation at break etc., while also needing to possess good high temperature resistance.Major part cable protective sleeve heat resistance at present
Difference, coefficient of thermal expansion is big, easy firing；Poor dimensional stability is easily deformed；Most cable protective sleeve lower temperature resistances are poor, become under low temperature
It is crisp, it is easy aging；Cable protective sleeve different performance determines its purposes in life in the industry, with advances in technology, right
Cable protective sleeve is modified never to stop research.In order to which cable protective sleeve end properties is continuously improved, so that cable is protected
Sheath meets different working environments, and carrying out targetedly modification to cable protective sleeve just seems particularly necessary.
Summary of the invention
The purpose of the present invention is to provide the preparation methods that a kind of wear-resistant tensile stretches cable.
The present invention to achieve the above object, using following technical scheme:
A kind of wear-resistant tensile stretches the preparation method of cable, includes the following steps:
(1) stranded conductor strand is made into one；
(2) knit molding conducting wire in strand and be externally wrapped with a layer insulating, insulating layer with a thickness of 1-3mm；
(3) coat one layer of oversheath in the external of insulating layer, the outer jointing jacket with a thickness of 2-5mm.
Wherein, the oversheath includes following quality groupings point: 45-52 parts of attapulgite, nano-corundum powder 15-18
Part, 10-13 parts of talcum powder, 15-18 parts of silicate compounds composition granule, 7-10 parts of dioctyl phthalate, ethene-vinyl acetate
5-8 parts of ester copolymer, 6-10 parts of butyl stearate, hexamethylene be carbonic ester 9-15 parts more, 8-13 parts of hydrocarbyl succinimide acid, high density are poly-
10-12 parts of propylene, 4-9 parts of vinyl carboxylate, 8-10 parts of coupling agent, 7-11 parts of plasticizer, 9-16 parts of abrasion resistance modifier.
Silvalin is filled between the insulating layer and the shielded layer.
Compared with prior art, the beneficial effects of the present invention are:
The cost of material of simple production process of the present invention, use is low, good energy saving property, by silicate compounds composition granule and receives
Rice schmigel, can increase the abrasion resistance and hardness of cable protective sleeve；By adding abrasion resistance modifier, can effectively improve each
Dispersibility of the filler in cable protective sleeve improves the stability of finished cable protective case, cable protection tackling of the invention
There is good wearability, particularly suitable as cable technical field, long service life.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, implement below with reference to best
The present invention is described in further detail for example.
(1) stranded conductor strand is made into one；
(2) knit molding conducting wire in strand and be externally wrapped with a layer insulating, insulating layer with a thickness of 1-3mm；
(3) coat one layer of oversheath in the external of insulating layer, the outer jointing jacket with a thickness of 2-5mm.
Wherein, the oversheath includes following quality groupings point: 45-52 parts of attapulgite, nano-corundum powder 15-18
Part, 10-13 parts of talcum powder, 15-18 parts of silicate compounds composition granule, 7-10 parts of dioctyl phthalate, ethene-vinyl acetate
5-8 parts of ester copolymer, 6-10 parts of butyl stearate, hexamethylene be carbonic ester 9-15 parts more, 8-13 parts of hydrocarbyl succinimide acid, high density are poly-
10-12 parts of propylene, 4-9 parts of vinyl carboxylate, 8-10 parts of coupling agent, 7-11 parts of plasticizer, 9-16 parts of abrasion resistance modifier.
Oversheath preparation method uses following step:
1) attapulgite, nano-corundum powder, talcum powder, silicate compounds composition granule are put into high-speed stirred after mixing
It in device, then by the coupling agent for weighing the parts by weight, is activated, speed of agitator is in 1000-2000r/min, stirring
Time 5-12min, whipping temp is at 120-150 DEG C；
2) the more carbonic esters of dioctyl phthalate, ethylene-vinyl acetate copolymer, butyl stearate, hexamethylene, hydrocarbon
Base succinic acid, high density poly propylene, vinyl carboxylate, stir evenly, and ultrasonic vibration 8-10min obtains mixed liquor；
3) mixed liquor that step 2) obtains is added in the blender that step (1) obtains, plasticizer is being added and wear-resisting is changing
Property agent be heated to 70-80 DEG C, mix 30-40min, be sent into double screw extruder, melting extrusion is cooling, vacuum drying, is ground into
The particle of 60-80 mesh to get.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
