Problems solved by technology

The pattern on the embossing roller generally imitates the design of natural leather. First design a small piece of pattern (for example, imitating the protrusion of pores), and then form a large piece of pattern by splicing small pieces of patterns. It is inevitable to leave a gap that is easy to be noticed at the splicing of two small patterns. stitching traces, resulting in uneven distribution of pores on the surface of the artificial leather and rough texture, which affects the simulation effect

Embodiment 1

[0031] In parts by weight, 30 parts of isodecyl acrylate, 5 parts of perfluoroalkyl ethyl methacrylate (ZonylTM), 20 parts of methoxypolyethylene glycol (350) monomethacrylate, 20 parts Tripropylene glycol diacrylate, 10 parts of trimethylolpropane triacrylate, 2 parts of fluorinated epoxy resin (see Chinese Patent CN 101497730A Example 1 for the preparation method), 4 parts of Irgacure 184, 5 parts of diethylenetriamine 1 part of resin sand with an average particle size of 50 microns. At room temperature, put the above-mentioned components into a container to mix, stir and disperse at a high speed, so as to promote the dissolution of the soluble solid components and obtain a uniform particle-containing component. Release coating.

[0032] Such as figure 1 As shown, a release paper for artificial leather comprises a base paper 1, a base coat 2 and a release coat 3 on one side of the base paper 1 surface.

[0033] The basic requirements for base paper 1 in the present inventi...

Embodiment 2

[0037]In parts by weight, 30 parts of isodecyl acrylate, 5 parts of perfluoroalkyl ethyl methacrylate (ZonylTM), 20 parts of methoxypolyethylene glycol (350) monomethacrylate, 20 parts Tripropylene glycol diacrylate, 10 parts of trimethylolpropane triacrylate, 2 parts of fluorinated epoxy resin (see Chinese Patent CN 101497730A Example 1 for the preparation method), 4 parts of Irgacure 184, 5 parts of diethylenetriamine , 1.4 parts of resin sand with an average particle size of 70 microns. At room temperature, put the above-mentioned components into the container successively to mix, stir and disperse at a high speed, so that the solubilized solid components are dissolved, and a uniform particle component is obtained. Release coating.

[0038] According to the method described in Example 1, the release coating containing particle components was coated on the base coat 2 to obtain the release paper 10 .

Embodiment 3

[0040] In parts by weight, 30 parts of isodecyl acrylate, 5 parts of perfluoroalkyl ethyl methacrylate (ZonylTM), 20 parts of methoxypolyethylene glycol (350) monomethacrylate, 20 parts Tripropylene glycol diacrylate, 10 parts of trimethylolpropane triacrylate, 2 parts of fluorinated epoxy resin (see Chinese Patent CN 101497730A Example 1 for the preparation method), 4 parts of Irgacure 184, 5 parts of diethylenetriamine , 2 parts of resin sand with an average particle size of 100 microns, at room temperature, put the above-mentioned components into the container in turn, mix, stir and disperse at a high speed, so as to promote the dissolution of the solubilized solid components, and obtain a uniform particle-containing component Release coating.

[0041] According to the method described in Example 1, the release coating containing particle components was coated on the base coat 2 to obtain the release paper 10 .

Abstract

The invention discloses release paint for artificial leather and release paper prepared by utilizing the release paint. The release paint comprises particle components, an average particle size of each particle component is 20-500mum; and the release paper consists of base paper and a bottom coating layer and a release coating layer which are subsequently attached on one side of the base paper surface, the release coating layer is formed by consolidation after being coated with the release paint comprising the particle components, and an average particle size of each particle component is larger than a thickness of the release coating layer. By the adoption of the release paint for artificial leather and the release paper prepared by utilizing the release paint, since irregular distributing bulges are formed on the release coating layer surface of the particle components, irregular distributing pores are correspondingly formed on the artificial leather surface manufactured by utilizing the release paper, higher simulation effects are provided, and the sense of rigidity caused by manual splicing decorative patterns is avoided.

Description

technical field [0001] The invention relates to the field of artificial leather processing and manufacturing, in particular to a release coating for artificial leather and a release paper prepared by using the release coating. Background technique [0002] Release paper, also known as release paper, is a kind of anti-adhesive paper that can prevent prepreg from sticking and protect prepreg from contamination. [0003] The release paper used in the production of artificial leather belongs to the coated release paper, which is the carrier and temporary template for the manufacture of polyurethane artificial leather (PU leather) and polyvinyl chloride artificial leather (PVC leather). Release paper usually has a two-layer structure: the first layer is the base paper as the base material, and the second layer is the release coating layer. The general manufacturing method is to coat a base coat on the base paper earlier to reduce the penetration of the release coating, then coat...
