Abstract
The utility model discloses a kind of high temperature leather release liners, including original paper layer, TPX tack coats and TPX release layers, TPX tack coats are that vicat softening temperature is 145 150 DEG C and TPX tack coat of the Rockwell hardness less than 50, and TPX release layers are that vicat softening temperature is 165 180 DEG C and TPX release layer of the Rockwell hardness more than 80.Using the TPX release layers of higher hardness, the decorative pattern on its surface and glossiness perfection can be transferred on leather, fixed effect is good, and the middle TPX tack coat relatively low using hardness, the then ability of TPX release layers and original paper layer can be increased, it is separately such a structure setting, so that the hardness transition change of whole release liners, fragility is small, it is heat-resist, stress crack resistant ability is strong, therefore release performance is good during high temperature (up to 210 DEG C), it is more easily peelable when Leather Factory uses, and it is highly stable, can repeatedly Reusability without reduce release performance, so as to reduce client's use cost.
Description
Technical field
The utility model is related to leather release liners technical field, and more particularly to a kind of PU artificial leathers, PVC artificial leather or PU are closed
Finished leather high temperature modification release liners.
Background technology
Leather release liners are a kind of special paper kinds that prevents adhesion, and english name is Leather Release Paper, mainly
Applied to the manufacture of polyurethane (PU) artificial leather and polyvinyl chloride (PVC) artificial leather product, and used during original PU and PVC manufactures
Paste resin, i.e., be coated on stainless steel band by stainless steel band method, after drying and moulding, then shuts out certain decorative pattern by cotton gin.
When using the production of leather release liners method, because leather release liners surface has certain glossiness and decorative pattern, and surface has
The release layer of superperformance, is coated with release layer surface with resin direct layering, and is crosslinked sizing by drying, solidification, then
Leather release liners, which are peeled off, can be prepared into the artificial leather product with certain gloss and decorative pattern.
Artificial synthetic leather release liners generally have double-decker：First layer is the body paper as base material, the second layer be from
Type coating.General manufacture method is first to use thermoplastic resin to be coated in thermal coating mode on body paper on body paper, embossing
And solidify, or be coated release top layer, embossing to prevent the infiltration of mould release first to apply one layer of primary coat on body paper and consolidate
Change, the release coating in surface is formed on priming coat.Composition, shaping and the curing technology of surface release layer are the passes for manufacturing release liners
Key.
In dermatine production, release liners will be subjected to 160-230 DEG C of baking temperature, based on the release of thermoplastic resin
Layer, it is difficult to reach such heatproof requirement.And the release resin of heat curing-type makees face coat and has very big excellent in terms of heat resistance
Gesture, but product in the market is still not ideal enough in terms of solvent resistant, release stability and reuse number of times.It is domestic at present
The release liners generally existing hardness of development is relatively low, solvent resistant and resistance to elevated temperatures are bad, release is poor and reuse number of times
Few the shortcomings of.In addition, used high temperature modification release liners mainly use the siliceous release layer for coating by epoxy acrylic resin, should
Coating hardness is high, and fragility is big, and manufacturing process is complicated, and production cost is high, and only Ji Jia suppliers of foreign countries can produce, it is necessary to
Import, it is expensive, and during for leather synthesis, because the big release layer of fragility is easily broken and can not use, reuse
Number of times is few, and access times only have 10 times or so, cause production cost higher；And it is siliceous, pollute environment.
In order to overcome disadvantages mentioned above, the positive research and innovation of the design people, to create a kind of high temperature resistant leather release liners.
