Embodiment 1

[0022] Embodiment 1: a kind of preparation method of Yangbuck mirror surface superfiber, comprises the following steps:

[0023] (1) Coating of the surface layer: take the colored yambuck resin to coat the surface layer. The colored yambuck material is made by mixing and dispersing polyurethane resin and yambuck foaming powder at a mass ratio of 100:20. The coating amount of Seyangba resin is 150g. After coating, put it in an oven and dry it. The temperature of the oven should not exceed 90°C;

[0024] (2) Secondary coating of the surface layer: the secondary coating of the surface layer is carried out with colored Yangbuck resin, the coating amount is 150g, after the coating is completed, it is placed in an oven for drying, and the temperature of the oven does not exceed 90°C;

[0025] (3) Coating of primer resin: use primer resin to coat the surface layer, and the coating amount is 200g;

[0026] (4) Semi-dry pasting of rough-grained lychee-grain release paper to make semi-...

Embodiment 3

[0042] Embodiment 3: a kind of preparation method of Yangbuck mirror surface microfiber, comprises the following steps:

[0043] (1) Coating of the surface layer: take the colored yambuck resin to coat the surface layer. The colored yambuck material is made by mixing and dispersing polyurethane resin and yambuck foaming powder at a mass ratio of 100:50. The coating amount of Seyangba resin is 180g. After coating, put it in an oven and dry it. The temperature of the oven should not exceed 90°C;

[0044] (2) Secondary coating of the surface layer: the secondary coating of the surface layer is carried out with colored Yangbuck resin, the coating amount is 180g, and it is dried in an oven after coating, and the temperature of the oven does not exceed 90°C;

[0045] (3) Coating of primer resin: use primer resin to coat the surface layer, and the coating amount is 250g;

[0046] (4) Semi-dry pasting of rough-grained lychee-grain release paper to make semi-finished leather, and then...

Abstract

The invention relates to a method for preparing yambuck mirror surface superfiber. Firstly, the colored yambuck resin is used to coat the surface layer twice, and then the primer resin is used to coat the surface layer, and the rough-grained lychee pattern is used to release the surface layer. Paper pairs are semi-dry pasted to make leather semi-finished products, which are placed in an oven for high-temperature foaming. The temperatures of the five heating zones in the oven are: 130°C, 140°C, 150°C, 160°C, and 165°C. The foaming time is 1 to 3 minutes, and finally adopt the three-knife veneer method to transfer the veneer, and prepare the Yangbuck mirror microfiber after drying. The preparation method of the invention is simple, the steps are easy to operate, the control of the foaming step and the feeding of the size on the release paper make the foaming degree of the surface and the bottom of the ditch different. The deformation spreads out while the bottom of the groove remains unchanged, making the texture on the microfiber unique.

Description

technical field [0001] The invention relates to a method for preparing yangbuck mirror superfiber, which belongs to the technical field of superfiber preparation. Background technique [0002] As a new type of high-grade artificial leather made of ultrafine fibers, microfiber leather can be used in various fields such as shoes, bags, furniture, and automotive interiors. It has the characteristics of genuine leather and has superior indicators than genuine leather. As the application of microfiber leather becomes more and more extensive, people have more and more requirements for the surface change of microfiber leather, especially for the surface texture of microfiber leather, but the existing microfiber leather mainly uses release paper Mainly veneer, there is no wet foaming layer of traditional polyurethane synthetic leather, so embossing cannot be used for texture modeling. Contents of the invention [0003] The purpose of the present invention is to solve the problem ...
