Description
Technical field
The present invention relates to a kind of adhesive tape and preparation method thereof, be applicable to be used in electrician's operation bare exposed conductor protective bag is tied up, particularly keep the occasion of long-time insulating property by autohension.
Background technology
In electric installation manufacturing, construction and use, the various terminals and the jointing of a large amount of electric wires, cable need insulate and encapsulation process to the position that may leak electricity with electrician's electric insulating sealant band.Commonly used at present mainly contains three types: first kind is the fabricbase insulation tape of black, is commonly called as electrician's splicing tape, is used to twine voltage and is no more than 380 volts wire joint; Second kind is the polyvinyl chloride insulation adhesive tape, and promptly PVC tape is commonly called as plastic adhesive tape, is mainly used in the wrapping of indoor and outdoor wire joint and automobile distribution and the insulation protection of electronic component, and voltage is no more than 600 volts; The third is an autohension rubber insulation sealant tape; also claim the high pressure self-adhesive tape; the annex that is used for electric wire joint and High-Voltage Insulation Protection Product generally is used for voltage between 1～10 kilovolt or the insulated enclosure below 30 kilovolts protection, its characteristic: high pressure resistant, sealing and insulative water-proof.
For autohension rubber insulation sealant tape, be that a class is based on polyisobutylene rubber and isoprene-isobutylene rubber or synthetic polyisoprene, the adhesive tape that autohension is good.At present, on the market such adhesive tape mainly contains two kinds: a kind of is no base material, with polyisobutene and isoprene-isobutylene rubber or synthetic polyisoprene is the autohension rubber of main body directly rolls into certain specification after mixing by the proportioning that designs gluing belt flake, compound and be rolled into discoid adhesive tape product with barrier film or interleaving paper again; Another kind has base material, and above-mentioned autohension rubber is rolled into the flexible well base material of the one deck of fitting again behind the gluing belt flake, and is such as ethylene-propylene rubber(EPR) sheet or flexible PVC film etc., compound and be rolled into discoid adhesive tape product with barrier film or interleaving paper again.
Because polyisobutene and isoprene-isobutylene rubber or good autohension and the sealing property of synthetic polyisoprene, the autohension rubber insulation sealant tape of above-mentioned no base material can be as sealant closely looping at the terminal and the jointing place of electric wire, sealing effectiveness is fine, but physical strength, wear-resisting general with withstand voltage properties, publication number is the patent of CN 1145937A, proposition no base material based on the autohension rubber compounding of polyisobutene and isoprene-isobutylene rubber or synthetic polyisoprene in introduce the bigger chloroprene rubber of polarity, again with fire retardant, tackifier, roll into self-adhesive rubber band after weighting agent etc. are mixing, improved the complete processing and the over-all propertieies such as flame retardant resistance and physical strength of no base material autohension rubber adhesive tape.The autohension rubber insulation sealant tape of base material is arranged, can strengthen its physical strength, wear-resisting and withstand voltage properties, but the stopping property aspect is not as the autohension rubber insulation sealant tape of corresponding no base material.
But prove in practice, above-mentioned which kind of autohension rubber insulation sealant tape all can not satisfy the insulated enclosure requirement under long-term water logging bubble or moist severe weather conditions well on the market, especially under the situation of the complex-shaped electric wire jointing of looping by hand.Analyze its reason, mainly be since present autohension rubber insulation sealing base-material no matter for the metal core of electric wire should for they the plastic peel base material bond properties inadequately, cause under long-term water logging or long-term moist severe weather conditions, destroy its sealing property and electrical insulation capability thereby water or aqueous vapor can penetrate into metallic conductor from adhesive interface gradually; And the imperfect reason of bond properties mainly is because the initial cohesiveness on present autohension rubber insulation seal gum adhesive tape base-material surface is relatively poor, makes its wetting capacity to metal core or plastic peel substrate surface also relatively poor.
Summary of the invention
The technical issues that need to address of the present invention are that existing autohension rubber insulation sealant tape is made improvements, a kind of improved composite electrical adhesive tape is provided, adopt the method for pressure-sensitive adhesive coating, tack by means of existing pressure sensitive adhesive is good, the good chemical property of infiltration diffustivity, realizes soaking in the water or still having the good insulation performance sealing property under the inclement weather conditions for a long time.
For addressing the above problem, comprise the base-material that rubber size rolls in the technical solution adopted in the present invention, crucial improvement is to have the pressure sensitive adhesive of diffusion fusion performance at surface-coated one deck of above-mentioned base-material.
Described pressure sensitive adhesive is wherein a kind of in solvent-type acrylic ester pressure-sensitive, solvent-borne type rubber pressure sensitive adhesive, hot-melting type acrylate pressure-sensitive adhesive or the hot-melting type thermoplastic elastic body rubber pressure sensitive adhesive.
Above-mentioned pressure sensitive adhesive must satisfy following performance: tack is minimum be 14,180 ° of stripping strengths must not be less than 6.0N/25mm, hold the minimum 8h of reaching of viscosity.
The step for preparing above-mentioned improved composite electrical adhesive tape comprises, 1. 2. the mixing of rubber sizing material rolls into base-material, and 3. base-material and barrier film or interleaving paper are compound, crucial improvement is to increase the following step in step front 3.: directly blade coating or spraying one deck pressure sensitive adhesive, the oven dry on the surface of base-material.
Above-mentioned pressure sensitive adhesive is meant the solvent-borne type pressure sensitive adhesive.
The another kind of technology for preparing improved composite electrical adhesive tape, 1. 2. the mixing of rubber sizing material rolls into base-material, 3. with the pressure sensitive adhesive blade coating on barrier film or interleaving paper, drying, 4. that barrier film or interleaving paper and base-material is compound, shift pressure sensitive adhesive to base-material.
Above-mentioned pressure sensitive adhesive is thermotropic pressure sensitive glue or solvent-borne type pressure sensitive adhesive.
At present, under long-term water logging or the moist severe weather conditions, the major cause that autohension rubber insulation sealant tape lost efficacy be not owing to its poor insulativity, but initial cohesiveness is relatively poor, makes its wetting capacity to metal core or plastic peel surface relatively poor.Improved composite electrical adhesive tape provided by the invention, not simply at surface-coated one deck pressure sensitive adhesive of base-material, but diffusion has taken place between base-material and the pressure sensitive adhesive, and having formed a diffusion layer on the microcosmic, i.e. the present invention is made of binder layer, diffusion layer and pressure-sensitive adhesive layer.In the structure of this product innovation, binder layer has been brought into play good insulation and self-adhesion, the good tack of pressure-sensitive adhesive layer improves its wetting capacity to metal core or plastic peel surface greatly, diffusion layer makes binder layer and pressure-sensitive adhesive layer combine together again, therefore improved composite electrical adhesive tape is when having the superior isolation performance, sealing property obviously improves, and has eliminated its hidden danger that lost efficacy easily at wet environment.
