Background technology
Up to the present, the surface of synthetic leather usually forms urethane resin layer with dry process, but this urethane resin layer does not have water vapo(u)r transmission, and promptly so-called aeration is low.By contrast, the urethane resin layer that forms with damp process does not have the problems referred to above, and because manufacture process can be simplified, has therefore become main flow gradually.
In using the synthetic leather manufacture method of this damp process, at first be on matrix, to be coated with polyurethane resin, make in coagulating basin that it solidifies, film forming, thereby form urethane resin layer.Subsequently, wash, drying, peel off matrix then, carry out various fine finishining as required, produce synthetic leather.
In the synthetic leather manufacture method of using this damp process, the matrix utilization that has been coated with polyurethane resin fills the coagulating basin of the dimethyl formamide aqueous solution and polyurethane resin is solidified, form urethane resin layer, because and then will be by the tank that is used to wash, therefore require its matrix to have resistance to water, for example, when using with paper to the operation paper of base material on matrix, this operation paper produces rough sledding such as crimping.
Therefore, have resistance to water in order to make matrix, for example, the spy opens and discloses a kind of synthetic leather wet type manufacturing operation paper that is pressed with thermoplastic resin film at least on the single face upper strata of resistance to water paper such as synthetic paper in the flat 10-168761 communique.
But coating will become the polyurethane resin of synthetic leather on this operation paper, when the polyurethane resin in making solidification layer solidifies, or when in tank, washing, difference according to circumstances, urethane resin layer might or stick out from operation paper, or produces and peel off.
On the other hand, in order to prevent the generation of above-mentioned situation, if on operation paper surface adhesive layer is set, then operation paper becomes and is difficult to peel off, and when the peeling strength polyurethane resin layer, has the problem of polyurethane resin fault rupture.
Therefore, wish to have a kind of wet type synthetic leather manufacturing operation paper always, its characteristics are: in coagulating basin or in the tank, urethane resin layer does not stick out from operation paper, do not produce and peel off, and in washing, dried stripping process, under the situation of not destroying urethane resin layer, have fissility than the appropriateness that is easier to peel off.
Summary of the invention
The object of the present invention is to provide a kind of in coagulating basin or the tank that is being used for washing, urethane resin layer does not stick out from the operation film, do not produce yet and peel off, and in stripping process, the wet type synthetic leather manufacturing operation film that the operation film is easy to peel off from this urethane resin layer with appropriate fissility.
The present inventor has carried out various researchs in order to achieve the above object repeatedly, and it found that:
(1) a kind of wet type synthetic leather manufacturing operation film wherein, on the single face at least of the matrix that is made of synthetic resin film, is provided with the peel ply that is made of the vistanex that has carried out peeling off control.
(2) according to the wet type synthetic leather manufacturing operation film of above-mentioned (1) record, wherein, the said polyolefins resin is a polypropylene.
(3), wherein, above-mentionedly peel off that to control be to make the said polyolefins resin contain the terpenic series phenol resin according to the wet type synthetic leather manufacturing operation film of above-mentioned (1) or (2) record.
(4) according to the wet type synthetic leather manufacturing operation film of any one record in above-mentioned (1)~(3), wherein, above-mentioned to peel off control be that corona treatment is carried out on the peel ply surface that is made of vistanex.
(5), wherein, between above-mentioned matrix and the peel ply that constitutes by vistanex, be provided with the improved polyalkene layer according to the wet type synthetic leather manufacturing operation film of any one record in above-mentioned (1)~(4).
(6) according to the wet type synthetic leather manufacturing operation film of any one record in above-mentioned (1)~(5), wherein, above-mentioned synthetic resin film is the polyethylene terephthalate film.Can address the above problem, thereby finish the present invention.
The invention is characterized in: on the single face at least of the matrix that constitutes by synthetic resin film, be provided with the peel ply that constitutes by the vistanex that has carried out peeling off control.
In the present invention, must use synthetic resin film as matrix.Matrix is decided to be synthetic resin film, and its advantage is: be easy to choose the material with transparency, paintedly be easy to differentiate when uneven when urethane resin layer produces, with low price relatively such as synthetic paper.
In addition, will be heated to more than 150 ℃ during owing to drying, preferred substrate has heat resistance, and then, if the matrix softness then is difficult to urethane resin layer is peeled, the therefore preferred synthetic resin film that uses type with hardness.
As synthetic resin film, as long as satisfy the desired condition of above-mentioned matrix, there is no particular restriction, and it comprises the film of polyether-ether-ketone, polyether-ketone, polyimides, polyether sulfone and mylar etc.Wherein, as the polyethylene terephthalate film of polyester resin film, it not only has heat resistance, hard advantage, and has solvent resistance, and is therefore preferred.
In addition, the thickness of the matrix that is made of synthetic resin film is not particularly limited the scope of preferred 20~125 μ m.If matrix thickness is thinner than 20 μ m, when then making synthetic leather,, consequently might on urethane resin layer, produce fold because the stress that exists on the matrix is easy to generate stretching.On the other hand, not only uneconomical if matrix thickness surpasses 125 μ m, and also under the identical situation of width, thickness is big more, and it is short more that the length of operation film will become, so the replacing frequency of the used roller of operation film improves the operability variation.
Be used to form the vistanex of peel ply among the present invention, it comprises for example polyethylene, polypropylene, polystyrene, ethylene-propylene copolymer resin, polybutene resin etc., especially, considers optimization polypropylene from the viewpoint of heat resistance and fissility.
Secondly, peel off first method of control as vistanex among the present invention, this method is to make this vistanex contain the terpenic series phenol resin.
Here, containing the vistanex of terpenic series phenol resin, as long as for containing the material of terpenic series phenol resin and vistanex, can be the material that is mixed with these resins, also can be copolymer.

The terpenic series phenol resin plays the effect of control urethane resin layer peeling force, and the content of terpenic series phenol resin is big more, and then the tendency of Chan Shenging is that the peeling force of peel ply becomes greatly.Therefore, the content by control terpenic series phenol resin can produce the operation film that is provided with peel ply, and this peel ply is made of the vistanex with required peeling force.
Consider above effect, for the vistanex of 100 weight portions, the content of terpenic series phenol resin is preferred 1~50 weight portion usually, and more preferably, its content is in the scope of 5~20 weight portions.In addition, by its content is defined in the scope of 1~50 weight portion, when the urethane resin layer that will become synthetic leather from the operation film is peeled off, can prevent to cross the destruction of the urethane resin layer that causes by force effectively owing to the adhesive strength of operation film and urethane resin layer.And then, if the content of terpenic series phenol resin in above-mentioned content range, its advantage is: the good fluidity of vistanex is coated with on matrix and becomes easy.
In addition, the number-average molecular weight of terpenic series phenol resin is preferred about 100~3,000, if in this scope, then effect is remarkable, and has easy-to-use advantage.
Secondly, peel off second method of control as vistanex among the present invention, this method is that corona treatment is carried out on the peel ply surface that is made of vistanex of film forming on matrix.That is, the operation film can be controlled and peeling force between the urethane resin layer of synthetic leather will be become by corona treatment.Particularly, if increase the power output of corona treatment, peeling force also increases, and therefore by the power output of control corona treatment, can make the operation film with required peeling force.The power output of corona treatment is generally 1~1.5kW, is generally 0.5~1.5 second in the processing time, and void pitch is to carry out corona treatment under 1~10mm.
And then the content control by making above-mentioned terpenic series phenol resin and the power output control combination of this corona treatment can realize the control that precision is higher.
By having carried out peel ply and the urethane resin layer that the above-mentioned vistanex of peeling off control constitutes, it is by the scope of the preferred 0.3~9.0N/3cm of peel strength of aftermentioned method mensuration.If peel strength is littler than 0.3N/3cm, then the manufacturing of wet type synthetic leather with the coagulating basin of operation in or the tank that is used for washing, urethane resin layer might stick out from the operation film, or generation is peeled off, if surpass 9.0N/3cm, when from the operation film urethane resin layer being peeled off, urethane resin layer might be out of shape, or fracture.
Peel ply that constitutes by the vistanex that contains above-mentioned terpenic series phenol resin and/or the peel ply that constitutes by the vistanex that has carried out above-mentioned corona treatment, the scope of preferred 10~150 μ m of its thickness.Its thickness preferably is because can bring into play better effect in this scope.
