Description
Technical field
The present invention relates to release paper fields, and in particular to a kind of release paper resistant to high temperature.
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；Polypropylene (PP) material making coatings can make release paper surface refractory, be not easy
Deformation, peeling effect is good, but PP material is not easy to combine with body paper, and polyethylene (PE) material making coatings can make between coating and body paper
There is higher bond strength, but do not have high temperature resistant and on-deformable characteristic, uses the mixing material of one layer of PE and PP at present
As the coating of release paper, so that the former base stock of release paper and release paper surface are easily-deformable, remove, service life is shorter, and table
Face does not have preferable high temperature resistant, on-deformable characteristic, and peeling effect is also bad.
Based on the above situation, the invention proposes a kind of release paper resistant to high temperature, problem above can effectively be solved.
Summary of the invention
The purpose of the present invention is to provide a kind of release papers resistant to high temperature.The paper membrane knot of release paper resistant to high temperature of the invention
It closes intensity, peel strength, high temperature resistance, the high comprehensive performances such as shrinking percentage, and release paper surface refractory, is unlikely to deform,
Coating and body paper are not easily stripped, long service life.
The present invention is achieved through the following technical solutions:
A kind of release paper resistant to high temperature, including body paper are successively arranged coating one, coating two on the body paper；The coating
One by including that the raw material of following parts by weight is made: the trade mark is 85~95 parts of the polypropylene of H2800, glycidyl methacrylate
5~15 parts of graft polypropylene；The coating two is by including that the raw material of following parts by weight is made: the trade mark is the polypropylene 90 of H2800
~98 parts, 2~10 parts of acrylamide graft polypropylene；It is squeezed out and is applied by die head after the coating one and coating two are compound in die head
It is overlying on body paper.
The paper membrane bond strength of release paper resistant to high temperature of the invention, peel strength, high temperature resistance, shrinking percentage etc. are comprehensive
Function admirable, and release paper surface refractory, be unlikely to deform, coating and body paper are not easily stripped, long service life.
Preferably, the coating one by include following parts by weight raw material be made: the trade mark be H2800 88 parts of polypropylene,
12 parts of glycidyl methacrylate graft polypropylene.
Preferably, the coating two is by including that the raw material of following parts by weight is made: the trade mark is the polypropylene 96.5 of H2800
Part, 3.5 parts of acrylamide graft polypropylene.
Preferably, the overall thickness of the coating one and coating two is 0.1~1mm.
Preferably, the ratio between thickness of the coating one and the coating two is 1:2~5.
Preferably, the polyacrylic grafting rate of the glycidyl methacrylate graft is 0.15~0.25%.
Preferably, the polyacrylic grafting rate of the acrylamide graft is 0.12~0.22%.
Preferably, it is equipped with the back side of leaching membrane layer in the body paper, is additionally provided with the coating of the polyvinyl chloride of 1~2g/m2.
Compared with prior art, the present invention have the following advantages that and the utility model has the advantages that
The paper membrane bond strength of release paper resistant to high temperature of the invention, peel strength, high temperature resistance, shrinking percentage etc. are comprehensive
Function admirable, and release paper surface refractory, be unlikely to deform, coating and body paper are not easily stripped, long service life.
The present invention abandons selecting the polypropylene and methacrylic acid contracting that the trade mark of proper proportion is H2800 using polyethylene
Water glyceride graft polypropylene, which is blended, is used as coating one, using glycidyl methacrylate graft polypropylene in molten condition
Lower good fluidity, penetrating power be strong and the feature strong with the adhesive force on body paper, increases middle layer, so that release 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 coated peeling effect good
The characteristics of, coating one makes coating one and body paper have higher knot due to the polyacrylic addition of glycidyl methacrylate graft
Intensity is closed, and coating one and coating two also have preferable bond strength, so that there have release paper surface covering and body paper to be higher
Bond strength so that the release paper produced have long service life, the good feature of peeling effect, the prior art produce from
Type paper service life is about 30 times, and the release paper service life that the present invention produces is about 70 times；It is carried on the back in conjunction in body paper
Face covers PVA coating, so that release paper is not easy to crimp in process of production and during producing artificial leather using release paper.
