Technical field
The utility model relates to synthetic leather release paper preparation fields, and in particular to a kind of production dress of mirror surface release paper
It sets.
Background technique
Leather release paper is made of body paper (paper substrate) and release coating (coating one layer of release layer i.e. on body paper),
Leather release paper is used for the forming and hardening of leather, and the leather fluid of hot melt is exactly coated in skin that is smooth or making decorative pattern
It removes from office in release paper, then puts them on the solidification of baking oven high temperature, molding leather is transferred to above felt, is thus obtained
Molding leather and fur products.The carrier that release paper is produced as artificial leather, may be reused, it replaces backward punching block flower
Plate, it has also become the inexorable trend of artificial leather production.
Traditional mirror surface release paper leveling fashion is mostly press polish, and there are many shortcomings for this method, as roll surface easily generates
Color difference easily draws silk, and the smoothness of paper is higher to felt wrapped roll and relevant device required precision.
The Chinese invention patent application of Publication No. CN104594117A discloses a kind of mirror surface mirror surface release used for artificial leather
The production method of paper is obtained by operation preparations such as press polish, radiation curings with high gloss using paint-on technique twice
Mirror surface release paper for synthesizing leather.But because there are easily draw silk, at high cost, product using calendering operation
The disadvantages of unstable quality.
The Chinese invention patent application of Publication No. CN101691717A discloses a kind of mirror surface release paper for synthesizing leather
Production method, using multi-layer coated technology, in body paper and one layer of adhesive layer containing organic/inorganic substance of release layer inter-coat,
The mirror surface release paper for synthesizing leather with high gloss is obtained by operation preparations such as press polish, heat cures.But the technique applies
The problems such as layer is more, and consistency problem easily leads to stomata, color difference between coating, is unable to meet production requirement.
The Chinese invention patent application of Publication No. CN 103938490A (application No. is 201410133962.4) discloses
A kind of production method of mirror surface artificial leather release paper is passed through using organic-silicon-modified alkyd resin as investment precoat
The operation preparations such as press polish, heat cure obtain the artificial leather release paper with high gloss.But because using heat cure, institute
With there are solvents not environmentally, the disadvantages such as curing rate is slow, and production efficiency is low.

Glossiness: glossiness is tested with the dedicated glossometer of WG75 paper.
Peel strength: smoothness is tested with DRK105 smoothness tester.
Table 1 lists the performance of the release paper of each embodiment and comparative example preparation.
Table 1
As can be seen from the data in the table, it is obvious to obtain product glossiness after Self-leveling technique is coated with release layer for coating
Increase, smoothly significantly improve, and there is mirror effect.
The foregoing is merely the specific implementation cases of the utility model patent, but the technical characteristic of the utility model patent is simultaneously
Not limited to this, in the field of the utility model, made changes or modifications all cover any those skilled in the relevant art
Among the scope of the patents of the utility model.
