The plastic-aluminum combined paper tinsel of oil film and preparation method
Technical field
The present invention relates to one both there is good gas-tight, waterproof, insulation effect are good, there is again peel strength high, there is again the little plastic-aluminum combined paper tinsel of oil film of cladding coefficient of friction and preparation method simultaneously, be mainly used in CATV electric wire, cable, heating wires, network layout, LAN, belong to oil film composite band and manufacture field.
Background technology
The applicant is all in first patent application CN201477915U, title " single-faced self-bonded aluminum foil ", it comprises aluminium foil, the bonding glue-line of one deck is equipped with between aluminium foil with PET film, PET film is equipped with the stripping glass intensity that one deck self-adhesive film needs to improve further between two-layer aluminium foil and PET, reduce return loss, improve the effect of self-adhesion; Secondly, plastic-aluminum combined paper tinsel skin-friction coefficient is large, when cladding optical cable, cable, easily causes the generation of belt phenomenon.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design one the present invention relates to one and had both had good gas-tight, waterproof, insulation effect are good, have again peel strength high, have again the little plastic-aluminum combined paper tinsel of oil film of cladding coefficient of friction and preparation method simultaneously.
Design: in order to realize above-mentioned purpose of design.1, aluminium foil two sides is the design of matsurface, is one of technical characteristic of the present invention.The object done like this is: the matsurface due to aluminium foil adopts the method for electric pulse to make, it gathers at the concaveconvex structure of aluminium foil surface, not only increase the roughness of aluminium foil surface, and its pit is cheated as Wedged with regard to You, it can make coating thereon anticorrosive coat when liquid state, its impregnating fluid Shen Ru Wedged cheats, and Wedged of Chenging with Xing after solidifying follows closely, thus guarantees that anticorrosive coat adheres firmly on the matsurface of aluminium foil.2, aluminum plastic film is compounded in the design on aluminium foil matsurface, is technical characteristic two of the present invention.The object done like this is: in plastic foil, wherein PVC Main Ingredients and Appearance is polyvinyl chloride, the superiors of this skin covering of the surface are paints, middle main component is polyvinyl chloride, orlop is back of the body coating adhesive, thickness is only 0.0065 ~ 0.0075mm, when itself and matsurface aluminium foil compound tense, not only adhesive strength is high, and bonding after still do not destroy the formation of its matsurface, because this ensure that PVC film aluminium foil due to point cantact in the coated process of optical cable, cable, its coefficient of friction is little, coated smooth and easy, not broken belt.3, aluminium foil another side scribbles the design of oil lamella, is technical characteristic three of the present invention.The object done like this is: because industrial stearic acid not only has stabilizing agent function, and there is fine lubricating function, it and wax, mineral oil heat the solution that obtains, there is the lubricity exceeding itself function, be coated in the surface of aluminium foil, the oil lamella obtained after cooling, its coefficient of friction is very little.When the plastic-aluminum combined paper tinsel of made oil-containing is at coated optical cable, cable, the plastic-aluminum combined paper tinsel of its oil-containing logical be overmolding to pattern time, its coefficient of friction is very little, can not cause the generation of oil lamella belt phenomenon, meets the demand of optical cable, cable coated length.
Technical scheme 1: the plastic-aluminum combined paper tinsel of a kind of oil film, comprises aluminium foil, described aluminium foil one side and plastic foil compound, aluminium foil another side scribbles oil lamella.
Technical scheme 2: the preparation method of the plastic-aluminum combined paper tinsel of a kind of oil film, the plastic-aluminum combined paper tinsel of its bag one side, the wax of weight 45%-55%, the mineral oil of 20-35% are become liquid with the stearic acid heating and melting of 15-30%, then be coated on the aluminium foil surface of the plastic-aluminum combined paper tinsel of one side, then adopt air-cooled cooling.
The present invention is compared with background technology, and one is that adhesive strength is high, and its bonding rear formed peel strength is tens times, hundreds of times of background technology; Two is insulation, shield effectiveness is good, and hot strength is good, and return loss is little; Three is that the heat resistance of plastic foil and cold resistance are extremely strong; Four is that parcel self-adhesion is good; Five is that coefficient of friction is little, coated smooth and easy, not broken belt; Five is that antioxidant effect is good, can effectively prevent air oxidation aluminium foil, make aluminium foil be in non-oxidized state.

Detailed description of the invention
Embodiment 1: with reference to accompanying drawing 1.The plastic-aluminum combined paper tinsel of a kind of oil film, comprises aluminium foil 1, and described aluminium foil 1 one side and plastic foil 2 compound, aluminium foil 1 another side scribbles oil lamella 3.It should be noted that: aluminium foil 1 both can represent paper tinsel, also can represent aluminium strip; Secondly, aluminium foil or aluminium strip face inherently matsurface, can directly buy used, also can carry out after-treatment according to actual needs.Described oil lamella 3 is made up of the stearic acid of the wax of weight 45%-55%, the mineral oil of 20-35% and 15-30%.
Embodiment 1-1: on the basis of embodiment 1, described oil lamella 3 by the wax of weight 50%, the mineral oil of 30% and 20% stearic acid form.
Embodiment 1-2: on the basis of embodiment 1, described oil lamella 3 by the wax of weight 50%, the mineral oil of 20% and 30% stearic acid form.
Embodiment 1-3: on the basis of embodiment 1, described oil lamella 3 by the wax of weight 45%, the mineral oil of 35% and 20% stearic acid form.
Embodiment 1-4: on the basis of embodiment 1, described oil lamella 3 by the wax of weight 55%, the mineral oil of 20% and 25% stearic acid form.
Embodiment 1-5: on the basis of embodiment 1, described oil lamella 3 by the wax of weight 50%, the mineral oil of 35% and 15% stearic acid form.
Embodiment 1-6: on the basis of embodiment 1, described oil lamella 3 by the wax of weight 45%%, the mineral oil of 25% and 30% stearic acid form.
Embodiment 2: on the basis of above-described embodiment, the preparation method of the plastic-aluminum combined paper tinsel of a kind of oil film, the plastic-aluminum combined paper tinsel of its bag one side, the wax of weight 45%-55%, the mineral oil of 20-35% are become liquid with the stearic acid heating and melting of 15-30%, then be coated on the aluminium foil surface of the plastic-aluminum combined paper tinsel of one side, the thickness of coating is selected as required, is generally less than 0.5mm, then adopts air-cooled cooling.
