Description
Technical field
The present invention relates to a kind of electrical protection technical field, particularly a kind of electric insulating tape and preparation method thereof.
Background technology
High-Voltage Insulation adhesive tape, for solving 600V-35KV High-Voltage Insulation problem, is mainly used in: 1. the joint process of various cable, continual-connecting-part process; 2. high power cord joint process, continual-connecting-part process; 3. high power cord joint, continual-connecting-part damage process; 4. cable and wire connector portions WATER REPELLENT; 5. above-mentioned cable and wire insulation division is repaired.What existing insulation tape generally adopted is that the mode spraying sizing material on the basement membrane of PVC material is produced, and such insulation tape does not have stretchiness, insulation thickness is thick, workability is bad, and its insulativity is also poor.If want to produce thinner High-Voltage Insulation adhesive tape, then must spray very thick glue-line on thinner basement membrane, this is a technical barrier at production link, and because basement membrane is too thin, glue-line is too thick, easily scalds basement membrane so can not produce.
The sealing major part of prior art cable splice uses PVC electrical adhesive tape.Shortcoming is that PVC weathering resistance and aging are poor, adds that the pressure sensitive adhesive time that PVC is coated with can be dry after long, after particularly encountering water, and some meeting infiltrations.When cable or fiber cable joint infiltration, resistance can increase.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of electric insulating tape, that a kind of material of gum adds self-adhesion gelatinous layer, the rubber sheath be used in together with cable surface on joint merges into an organic whole, this material has again fabulous weathering resistance, high thermal resistance and insulativity, makes cable and optical cable without any energy consumption and the loss of signal
A kind of electric insulating tape, comprise basement membrane and be attached to epilamellar gelatinous layer, described basement membrane adopts polypropylene, the quality proportioning of gelatinous layer is as follows: tetrafluoroethylene rubber 10-20 part, iso-butylene ethylene copolymer 15-30 part, SYNPERONIC PE/F68 10-25 part, nano aluminium oxide 10-20 part, superfine talcum powder 15-30 part, rosin 0.5-1.5 part, dimethyl siloxane 1.0-5.0 part, resol 1.0-1.5 part, carbon black 1.0-2.0 part, softening agent 1.0-2.0 part, oxidation inhibitor 1.5-3.0 part.
Described polyacrylic molecular weight is 20000-100000, and preferred molecular weight is 20000-50000.
Described oxidation inhibitor is alkylated phenthazine, pentanoic, the one in dithiocar-bamate, preferably pentanoic.
Described softening agent is one or more in dioctyl phthalate (DOP), dimixo-octyl phthalate, phthalic acid two (2-ethylhexyl) ester.
Beneficial effect of the present invention is: the present invention take polypropylene as basal lamina material, and polypropylene has good ductility and toughness, and basement membrane thickness can be controlled in thinner scope, its polypropylene material is also fine to the adhesiving effect of gelatinous layer.SYNPERONIC PE/F68 has good adhesive capacity and insulating property and has good low water absorbable and low water permeate makes the electrical insulating property of adhesive tape better; Tetrafluoroethylene has excellent electrical insulating property, but machining property is not good, iso-butylene ethylene copolymer add the processing characteristics greatly can improving tetrafluoroethylene, and further strengthen its electrical insulation properties.Add that autohension and the high thermal resistance of this adhesive tape basementmembrane self become a kind of rare selection of Electric Wires & Cables joint winding.After mixing, the present invention has high weathering resistance, high thermal resistance and insulativity.
The preparation method of adhesive tape of the present invention, comprises the following steps:
The production of step 1, basement membrane, basement membrane selects polypropylene GRANULES, through extrusion molding, press mold, rolling, unreels, makes required basement membrane;
Step 2, refining rubber master batch; First tetrafluoroethylene rubber, iso-butylene ethylene copolymer are thin squeezes, progressively add SYNPERONIC PE/F68 and resol, nano aluminium oxide is added after the polymer substance first added mixes, superfine talcum powder, rosin and carbon black, finally add softening agent, oxidation inhibitor and dimethyl siloxane;
Step 3, compound, recombination process main products is that work in-process are not namely by the adhesive tape that size is cut; On the basement membrane obtained in step 1 by coating technique compound by the rubber master batch refined, in gluing process, basement membrane first should carry out roughening pre-treatment to surface of adherence, increases adhesive tape to the sticking power of gelatinous layer;
Step 4, cut, dicing process act as cuts the adhesive tape produced in step 4 according to size.
Wherein, the refining of rubber master batch is carried out in kneader, and temperature controls at 150-220 DEG C.
