Abstract
The utility model provides a kind of release liners, including body paper, is sequentially provided with coating two, coating one on body paper, the thickness of coating two accounts for the 1/5 ~ 1/3 of total coating layer thickness, at the back side of the body paper covered with coating one and coating two, is also covered with 1 ~ 2g/m2PVA coating.The utility model has service life length using coating two and the body paper back side PVA setting, and peeling effect is good, the characteristics of being not easy to crimp.
Description
Technical field
A kind of release liners are the utility model is related to, are used for transfer coated processing as carrier.
Background technology
Release liners need to be widely used in industrial processes, are the transfer coated indispensable carriers of processing, from
Type paper surface needs high temperature resistant, is unlikely to deform；PP materials making coatings can cause release liners surface refractory, be unlikely to deform, stripping
It is good from effect, but PP materials are not easy to combine with body paper, and PE materials making coatings can make have higher combination strong between coating and body paper
Degree, but do not have high temperature resistant and on-deformable characteristic, one layer of PE and PP mixing material is used as the painting of release liners at present
Layer so that the former base stock of release liners and release liners surface are yielding, peel off, and service life is shorter, and surface is without preferably resistance to
High temperature, on-deformable characteristic, peeling effect is also bad, therefore, invents a kind of new release liners and seems very necessary.
Utility model content
For the defects of prior art problem, the utility model provides a kind of release liners, easy to solve release liners surface
Peel off, yielding, the problem of service life is shorter.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of release liners, including body paper,
Coating two, coating one are sequentially provided with body paper, the thickness of coating two accounts for the 1/5~1/3 of total coating layer thickness, in body paper covered with painting
The back side of layer one and coating two, is also covered with 1~2g/m2PVA coating.
Coating one is PP, and coating two is PP/PE compounds.
Compared with prior art, the utility model has the advantages that：
1st, release liners surface refractory, be unlikely to deform and need transfer coated peeling effect good, coating and body paper be not easy-peel
From service life length.
2nd, curling problem of the release liners production process neutralization during paper production artificial leather itself is improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：
1- coatings one, 2- coatings two, 3- body paper, 4-PVA.
Embodiment
The utility model is described further below in conjunction with accompanying drawing：
Embodiment one：
As shown in Figure 1
The utility model provides a kind of release liners, including body paper, and coating two, coating one, coating two are sequentially provided with body paper
Thickness account for the 1/5 of total coating layer thickness, at the back side of the body paper covered with coating one and coating two, be also covered with 1~2g/m2's
PVA coating.
Coating one is PP, and coating two is PP/PE compounds.
Embodiment two：
As shown in Figure 1
The utility model provides a kind of release liners, including body paper, and coating two, coating one, coating two are sequentially provided with body paper
Thickness account for the 1/3 of total coating layer thickness, at the back side of the body paper covered with coating one and coating two, be also covered with 1~2g/m2's
PVA coating.
Coating one is PP, and coating two is PP/PE compounds.
Embodiment three：
As shown in Figure 1
The utility model provides a kind of release liners, including body paper, and coating two, coating one, coating two are sequentially provided with body paper
Thickness account for the 1/4 of total coating layer thickness, at the back side of the body paper covered with coating one and coating two, be also covered with 1~2g/m2's
PVA coating.
Coating one is PP, and coating two is PP/PE compounds.
The utility model utilizes PE this strong feature of good fluidity, penetrating power in the molten state, increases intermediate layer, makes
Release liners face coat one because PP materials cause release liners surface to have high temperature resistant, are unlikely to deform, and need to turn in production process
The characteristics of coating stripping effect is good is moved, coating two makes coating one and body paper have higher bond strength, and coating due to PE materials
One and coating two also have preferable bond strength so that release liners face coat and body paper have higher bond strength so that
The release liners produced have the characteristics of service life length, peeling effect is good, the release liners service life that prior art is produced
About 30 times, the release liners service life that the present invention produces is about 60 times；Applied in conjunction with body paper back side covering PVA
Layer so that release liners are not easy to crimp in process of production and during producing artificial leather using release liners.
Using technical scheme described in the utility model, or those skilled in the art is in technical solutions of the utility model
Under inspiration, similar technical scheme is designed, and reaches above-mentioned technique effect, is to fall into protection model of the present utility model
Enclose.
