Description

Air-flotation high-speed silicon coating machine for production of release paper

Technical Field

The invention relates to the technical field of printing and coating equipment, in particular to an air-flotation high-speed silicon coating machine for production of release paper.

Background

The release paper method is the most common process for producing artificial leather and synthetic leather in the prior art, and has the action principle as follows: the surface layer material of the leather-like product, such as acetone solution of polyurethane, is directly and flatly coated on the surface of the release paper by a roller coating method by taking the release paper which is prefabricated with a leather grain pattern or has no pattern as a carrier, then the release paper is dried and heated for plasticization, a middle layer or a foaming layer or a bottom layer and a bonding layer can be further coated according to requirements, and then a base fabric is flatly coated on the release paper, and finally the release paper (carrier) with the leather grain pattern or the pattern-free layer is stripped from the surface layer after heating for plasticization, so that the leather grain pattern or the synthetic leather coating on the release paper is formed on the surface layer, thereby realizing the purpose of leather-like.

The artificial leather release paper is used as paper in the process of synthetic leather production, can endow the surface of the synthetic leather with patterns and hand feeling which are comparable to those of genuine leather, and is a carrier and a temporary mold in the synthetic leather production. In the prior art, the specific production method of the artificial leather release paper is approximately as follows: firstly, coating a release resin layer on the surface of base paper, solidifying, and then embossing the release resin layer to obtain the artificial leather release paper with patterns on the surface.

For example, publication numbers are: chinese patent application CN103938490A discloses a production process of polymer leather release paper, which specifically comprises the following steps: coating oxidation-resistant liquid glue on the back of the base paper, instantly drying the base paper at high temperature by hot air, carrying out ultraviolet UV curing treatment, conveying the base paper to a composite embossing unit, pushing the multi-layer polymer resin to a gap type flow reducing spray head with high temperature and high pressure by a hot reflux high-speed smelting and pushing device, uniformly spraying the multi-layer polymer resin on the front of the base paper to form semi-permeable combination with the base paper, simultaneously carrying out mechanical embossing, combining a polymer material with the base paper to form leather patterns, trimming and finishing, and then rolling to obtain the polymer leather release paper. The process can increase the embossing speed to 40-80 meters per minute, and effectively improve the production efficiency of leather products. However, the process and the traditional process mainly have the following defects: 1) the pattern is formed by embossing, and the definition of the pattern is not as clear and accurate as the printed pattern; 2) the release resin layer is not treated by silicone oil coating, so that the situation that the release resin layer is difficult to peel still exists during peeling, and pattern deformation can be caused in serious cases; 3) by adopting a thermal curing mode, the phenomena of curling, wrinkling and the like of release paper are easily caused by high-temperature treatment; 4) the whole processing speed is low, and the processing efficiency is low.
