Description
Technical field
The present invention relates to electric power project engineering field, be specifically related to a kind of cable.
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 cover layer of high-insulation.
Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, mining cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.
Therefore cable is being played the part of very important role in industry-by-industry, and in order to prevent accident, its fire protecting performance must be protected, and prior art is difficult to meet this requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cable, to solve deficiency of the prior art.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of cable, it is characterized in that, comprise from the inside to the outside coaxial core, filler and the cover layer arranging successively;
The component of described covering layer material and parts by weight are: polyolefin elastomer 60-70 part, magnesium hydroxide powder 20-30 part, aluminium-hydroxide powder 30-40 part, magnesium oxide powder 1-2 part, aerosil 1-2 part, coupling agent 0.2-1 part, plasticiser 5-7 part, crosslinking agent 1-3 part; Wherein, described polyolefin elastomer is POE8450; Described coupling dosage is ethyl alkene silane coupling agent; Described plasticiser is or trioctyl trimellitate (TOTM); Described crosslinking agent is cumyl peroxide.
Described tectal preparation method comprises and comprising the following steps:
(1) will press polyolefin elastomer, the magnesium hydroxide powder of formula rate, aluminium-hydroxide powder, magnesium oxide powder, aerosil are put into banbury, at 100 DEG C mixing 20 minutes;
(2) add again the surplus stock by formula rate, at 85 DEG C mixing 10 minutes, then at 75 DEG C mixing 10 minutes;
(3) double screw extruder extruding pelletization, obtains covering layer material
The polyolefin elastomer 8450 that main sizing material adopts E.I.Du Pont Company to produce, POE has the general physical property of thermoplastic elastomer (TPE), as mouldability, waste material recycling and cured properties etc., and relative density is little, thereby volume is cheap, thermal endurance, cold resistance excellence, scope of application broadness, weatherability, resistance to ag(e)ing are good.The performances such as oil resistance, compression resistant permanent deformation and abrasion performance are general.Be applicable to thermal endurance and environment resistantly require high insulating barrier electric wire is industrial.POE physical property is close to general plastic material, but has again vulcanizing of rubber simultaneously concurrently, can conformability, and its use, has not only ensured the properties of insulation, and is beneficial to post-cure processing, has reduced formula rubber shape possibility.
Magnesium hydroxide powder 20-30 part, aluminium-hydroxide powder 30-40 part is used in conjunction with by a certain percentage, is good fire proofing.
Described cover layer internal layer is coated with scolds water flame retardant coating, described component and parts by weight of scolding water resistance combustion coating material are: polyethers 40-60 part, epoxy resin 5-8 part, polytetrafluoroethylene 5-15 part, magnesium hydroxide powder 3-5 part, aluminium-hydroxide powder 2-3 part, phthalic acid ester 1-2 part, polyurethane 10-15 part, dimethicone 1-5 part, aerosil 5-10 part, ethanol 30-50 part.
The described preparation method who scolds water resistance combustion coating material, concrete steps comprise:
[1] first will mix by the polyethers of formula rate, epoxy resin, polytetrafluoroethylene, magnesium hydroxide powder, aluminium-hydroxide powder, phthalic acid ester, be then uniformly mixed reaction 3h at 80-160 DEG C;
[2] after mixing according to formula rate by the polyurethane of formula rate, dimethicone, aerosil, ethanol, add hot reflux 16h again;
[3], by the mixing of materials of step [1] and step [2] gained, then ultrasonic dispersion 100min, obtains scolding water resistance combustion coating material.
It is 92.2-95 ° that the feeler analyzer of this coating detects water contact angle, under-15 low temperature environment, peel off without embrittlement, nothing, and at 0.8MPa, nothing infiltration under the 20min degree of depth, function admirable.
The beneficial effect of technique scheme of the present invention is as follows:
In such scheme, cable of the present invention can reach flame retardant grade UL94-V0 level, and fire-proof and water-proof performance is all good, can be widely used in every field, has good market prospects.
