Abstract
The present invention provides a kind of novel release paper, is stacked gradually by body paper, coating one and coating two；Coating one is mixed by PE and PP, and it is 95% ~ 75% that wherein PE mass percent, which is 5% ~ 25%, PP mass percent,；Coating two is also mixed by PE and PP, and it is 100% ~ 95% that wherein PE mass percent, which is 0% ~ 5%, PP mass percent, has long service life, peeling effect is good, is not easy the characteristics of crimping.
Description
Technical field
The present invention relates to a kind of release papers, are used for transfer coated processing as carrier.
Background technique
Release paper needs to be widely used in industrial processes, is the transfer coated indispensable carrier of processing, from
Type paper surface needs high temperature resistant, is unlikely to deform；PP material making coatings can make release paper surface refractory, be unlikely to deform, stripping
It is good from effect, but PP material is not easy to combine with body paper, and PE material 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, use the mixing material of one layer of PE and PP as the painting of release paper at present
Layer, so that the former base stock of release paper and release paper surface are easily-deformable, remove, service life is shorter, and surface is without preferable resistance to
High temperature, on-deformable characteristic, peeling effect is also bad, therefore, invents the new release paper of one kind and is very necessary.
Summary of the invention
For the defects of prior art problem, the present invention provides a kind of release paper, easily peelable to solve release paper surface,
It is easily-deformable, the shorter problem of service life.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: a kind of release paper, including body paper, body paper
On be successively arranged coating one, coating two；Coating one is mixed by PE and PP, and wherein PE mass percent is 5% ~ 25%, PP matter
Measuring percentage is 95% ~ 75%；Coating two is also mixed by PE and PP, and wherein PE mass percent is 0% ~ 5%, PP mass percentage
Than being 100% ~ 95%；
By die head Extrusion Coating on body paper after coating one and coating two are compound in die head.
Coating one is mixed by 10% PE and 90% PP.
The thickness of coating one accounts for the 1/5 ~ 1/3 of total coating layer thickness.
It is covered with the back side of coating one and coating two in body paper, is also covered with 1 ~ 2g/m2PVA coating.
Compared with prior art, the invention has the following beneficial effects:
1, release paper surface refractory, be unlikely to deform and need transfer coated peeling effect good, coating and body paper be not easy-peel
From long service life.
2, improve curling problem of the release paper production process neutralization during paper production artificial leather itself.
Detailed description of the invention
Fig. 1 be single layer leaching PP(or PP and PE mixture) film production release paper test data.
Fig. 2 is the release paper test data of double-layer coextrusion method production.
Specific embodiment
The invention will be further described for specific embodiment:
Embodiment one:
A kind of release paper, including body paper are successively arranged coating one, coating two on body paper；Coating one by PE and PP mixing and
At it is 95% that wherein PE mass percent, which is 5%, PP mass percent,；Coating two is made of PP；
The thickness of coating one accounts for the 1/5 of total coating layer thickness.
It is covered with the back side of coating one and coating two in body paper, is also covered with 1g/m2PVA coating.
Embodiment two:
A kind of release paper, including body paper are successively arranged coating one, coating two on body paper；Coating one by PE and PP mixing and
At it is 75% that wherein PE mass percent, which is 25%, PP mass percent,；Coating two is also mixed by PE and PP, wherein PE matter
It is 95% that amount percentage, which is 5%, PP mass percent,；
The thickness of coating one accounts for the 1/3 of total coating layer thickness.
It is covered with the back side of coating one and coating two in body paper, is also covered with 2g/m2PVA coating.
Embodiment three:
A kind of release paper, including body paper are successively arranged coating one, coating two on body paper；Coating one by PE and PP mixing and
At it is 90% that wherein PE mass percent, which is 10%, PP mass percent,；Coating two is also mixed by PE and PP, wherein PE matter
It is 98% that amount percentage, which is 2%, PP mass percent,；
The thickness of coating one accounts for the 1/4 of total coating layer thickness.
It is covered with the back side of coating one and coating two in body paper, is also covered with 1.5g/m2PVA coating.
By die head Extrusion Coating on body paper after coating one and coating two are compound in die head: first by PP and PE according to coating
One and the proportion of coating two distinguish that melting mixing is uniform, and two kinds of coatings enter die head by double-layer coextrusion in a reservoir, two kinds apply
Layer respectively enters die internal, the channel one and channel two that die internal has vertical clapboard that die head is divided into left and right, one He of channel
Channel two is connected in die internal close to die head exit straight down, and two kinds of coatings converge in die head, then from die head mouth
It squeezes out and is covered on the surface of body paper straight down.
The present invention utilizes PE this strong feature of good fluidity, penetrating power in the molten state, increases middle layer, so that from
Type paper surface covering two due to PP material makes release paper surface have high temperature resistant, be unlikely to deform and production process in need transfer to apply
The good feature of layer peeling effect, coating one make coating one and body paper have higher bond strength, and one He of coating due to PE material
Coating two also has preferable bond strength, to make release paper surface covering and body paper have higher bond strength, so that production
Release paper out has long service life, and the good feature of peeling effect, the release paper service life that the prior art is produced is general
It is 30 times, the release paper service life that the present invention produces is about 60 times；PVA coating is covered in conjunction at the body paper back side, is made
Release paper is obtained to be not easy to crimp in process of production and during producing artificial leather using release paper.
Using technical solutions according to the invention or those skilled in the art under the inspiration of technical solution of the present invention,
Similar technical solution is designed, and reaches above-mentioned technical effect, is to fall into protection scope of the present invention.
