Description
Technical field:
The utility model relates to a kind of stretched plastic of two layers of unidirectional at least film utilizes binding agent compound for the multiaspect drag-resisting film, vertically form the tubular periosteum more again after the simple tension after being particularly related to tubular film double-layer overlapping, be that 15 ° to 75 ° of axis deviations dissect the tubular film with the longitudinal stretching direction be the flat film that draw direction and the edge that dissects the film of flattening are 15 ° to 75 ° of angle of deviations, make its two-layer at least draw direction relatively mutually the cross-utilization light-curing adhesive with its compound solidifying binding agent compounded multiaspect drag-resisting compound film of using up for the multiaspect drag-resisting film.
Background technology:
With the immediate technology of the utility model be United States Patent (USP) (patent No. 3342657), the technology of this patent disclosure is that the tubular film is behind longitudinal stretching, with the longitudinal stretching direction is axis, along the tubular circumference and be certain angle excursion with axis and cut the tubular film, with its continuous parting-cut and rolling, this moment the stretch orientation direction with dissect the film edge of finishing and be a fixed inclination, be generally 60 ° ~ 75 ° and then two films be the X-shape attitude by its oblique angle and be combined with each other and become the composite membrane of bidirectional stretch.But it is the longitudinal stretching under what state between following temperature of viscous state or viscous state and the above temperature of glassy state temperature that this film is determined tubular film film when vertical drawing.Also not having between clear and definite two films is to utilize which kind of binding agent compound, just say into weak bonding compound.Be to the film longitudinal stretching during longitudinal stretching by inside and outside two groups of annular nip rolls, at this moment since two groups of annulars nip rolls is actual can not clamp the tubular film, make it to be difficult to produce longitudinal stretching, the film of this moment endwise tensile strength in fact there is no increase, the tensile strength of this composite membrane reality is very low, the tensile strength of not bringing into play its draw direction behind the plastic foil stretch orientation increases by this excellent properties of four to ten times, and tensile strength and tear resistance improve and be not obvious.
The utility model content:
In view of above reason, the purpose of this utility model is in order to provide a kind of the tubular periosteum to be had 2 to 9 times the abundant longitudinal stretching of high multiple, so that the film after compound has high bidirectional stretch intensity and tear resistance even multiaspect drag-resisting, the compound multiaspect drag-resisting tear-proof film of tear resistance obvious results simple tension film.Another purpose of the present utility model is to use up solidifying binding agent compounded multiaspect drag-resisting compound film in order to provide.
The purpose of this utility model is achieved like this:
The utility model is used up solidifying binding agent compounded multiaspect drag-resisting compound film, multiaspect drag-resisting compound film is at least three layers, wherein there is two-layer at least big molecule to be stretched film and light-curing adhesive layer that the stretch orientation direction is arranged, the big molecular orientation orientation of this stretched film is 15 ° to 75 ° directions with this film edge or longitudinal axis and arranges, at least the big molecular orientation direction after two-layer stretched film stretches it is intersects situation each other relatively by the light-curing adhesive bonding formation multiaspect drag-resisting compound film that is combined with each other, and adhesive layer is to possess cementitiousness after utilizing ultraviolet light irradiation to make to be coated on the light-curing adhesive layers of polymer of the acrylic acid series on stretched film surface to solidify and stretched film is bondd.Because the simple tension film is below the viscous state temperature, the glassy state temperature is above to stretch, the big abundant unidirectional orientation of molecule has produced very high unidirectional tensile strength, be that spirality is dissectd when dissecing, vertically move speed and the circumference speed coupling between the speed that rotatablely moves according to tubular-film, can obtain the flat film that stretch orientation direction and film edge are certain oblique angle, vertically moving speed and the circumference speed that rotatablely moves as tubular-film equates, its stretch orientation direction of the flat film of the stretching that obtains after then spirality is dissectd and film edge are 45 ° of angles, big molecular orientation direction after the two-layer flat film that this dissects flattening stretches it is intersects situation each other and is combined with each other relatively and forms compound multiaspect drag-resisting tear-proof film, adopt the light-curing adhesive bonding between at least two flat films of stretching in addition, the adhesive fastness height, the cured strength height, making at least, two membranes produces the tension higher than known technology, tear resistance, light-curing adhesive can adopt urethane acrylate (PUA) light-curing adhesive, to draw behind the ultraviolet light irradiation polymerizing curable and stretch the film secure bond and be combined with each other and become multiaspect drag-resisting compound film or light-curing adhesive and adopt polyester acrylate (PEA) light-curing adhesive, behind the ultraviolet light irradiation polymerizing curable stretched film secure bond being combined with each other becomes multiaspect drag-resisting compound film.
Above-mentioned use up solidifying binding agent compounded multiaspect drag-resisting compound film, have at least one deck stretched film compound with it the in advance hot melt polymeric layer easy to connect that still is amorphous form after simple tension of one deck to be arranged in the opposite one side of light-curing adhesive layer.This layer hot melt articulamentum is that the coextrusion when extruding pipe-shaped membrane of simple tension film is lip-deep in stretched film.Because the outermost layer at composite membrane is the polymer film of one deck heat sealability excellence, the use and the utility function of this composite membrane are not fully exerted, the professional person knows, though the crystallinity stretched film has very high intensity along draw direction, but it is very difficult that heat-sealing between them is got up, melt temperature is low, and heat-sealing or heat seal are not firm, the temperature height just destroyed its molecular orientation, make the loss of fusion points film strength make film lose the tensile strength of stretched film too greatly, the polymeric layer that one deck heat sealability excellence is arranged on stretched film, just can be when the stretched film fusion being connected or seals, only hot sealing layer is produced welding, and do not have influence on the intensity of stretch film layers, or influence tensile strength and be no more than 50%.
Above-mentioned use up solidifying binding agent compounded multiaspect drag-resisting compound film, two-layer stretched film skin middle and/or two-layer stretched film has the vertically monoway stretch-oriented or horizontal monoway stretch-oriented film of one deck at least, compound between the film by light-curing adhesive layer bonding, middle and/or outer surface increase one deck simple tension film cross directional stretch or longitudinal stretching of two-layer stretched film, make this composite membrane have multiaspect drag-resisting, tear resistance, better intensity and tear resistance are arranged with the particularly weak film that bonds of known composite membrane.
It is in light weight that the utility model is used up solidifying binding agent compounded multiaspect drag-resisting compound film, and the combined strength bination height is durable in use, in that to be on 45 ° of directions tear-resistant effect remarkable on the warp-weft two-way and with direction of warp and weft.Cost is low, stretches and compound reliable easily row.
