Problems solved by technology

[0002] Traditional artificial leather has a single color, and the surface needs to be combined with various colors and patterns through printing and other subsequent processes. When it is used, the overall sense is rigid and dull, not dazzling and bright enough.
At present, in order to make synthetic leather more environmentally friendly, in terms of synthetic leather, the application of water-based resins is now being vigorously promoted, and most of the existing technologies use finished products prepared by raw material suppliers of water-based treatment agents. The disadvantage of this material is its fluidity during use. Not good, the brightness distribution of the finished product is uneven, the brightness is not natural enough, and the crystal transparency is not obvious

Embodiment 1

[0023] A water-based polyurethane synthetic leather treatment agent is characterized in that it is prepared from the following raw materials in terms of mass percentage: 99.5% of water-based polyurethane emulsion and 0.5% of tackifier. The viscosity of the treatment agent is controlled at 100cps.

[0024] Described water-based polyurethane emulsion is the water-based polyurethane emulsion of the model AD901 that Shanghai Zhonghaojing Industrial Co., Ltd. produces. Described tackifier is the polyurethane associative thickener of model T8020 produced by Shanghai Zhonghaojing Industrial Co., Ltd. The high-temperature-resistant transparent film adopts commercially available products, such as the high-temperature-resistant white transparent pet release film of the model GDY-GJ-06 produced by Shenzhen Everbright Adhesive Products Co., Ltd.

[0025] The preparation method of water-based polyurethane synthetic leather is carried out in the following steps:

[0026] 1) Preparation of...

Embodiment 2

[0029] The water-based polyurethane synthetic leather treatment agent is prepared from the following raw materials in terms of mass percentage: 99.6% water-based polyurethane emulsion and 0.4% tackifier. The viscosity of the treatment agent is controlled at 150cps.

[0030] The preparation method of water-based polyurethane synthetic leather is carried out in the following steps:

[0031] 1) Preparation of treatment agent: first water-based polyurethane emulsion and tackifier are prepared according to the formula ratio of the first purpose of the present invention, then stirred at normal temperature, the stirring speed is 500 revolutions per minute, stirred for 4 minutes, and the viscosity was controlled at 150cps; get treatment agent;

[0032] 2) Roll the prepared treatment agent on the textured synthetic leather through the mesh wheel of the printing machine. The printing speed of the roller coating is controlled at 28 m / min. The surface of the synthetic leather forms a cr...

Embodiment 3

[0035] The water-based polyurethane synthetic leather treatment agent is prepared from the following raw materials in terms of mass percentage: 99.7% water-based polyurethane emulsion and 0.3% tackifier. The viscosity of the treatment agent is controlled at 200cps.

[0036] The preparation method of water-based polyurethane synthetic leather is carried out in the following steps:

[0037] 1) Preparation of treatment agent: first water-based polyurethane emulsion and tackifier are prepared according to the formula ratio of the first purpose of the present invention, then stirred at normal temperature, the stirring speed is 500 revolutions per minute, stirred for 5 minutes, and the viscosity was controlled at 200cps; get treatment agent;

[0038] 2) Roll the prepared treatment agent on the textured synthetic leather through the mesh wheel of the printing machine. The printing speed of the roller coating is controlled at 30 m / min. The surface of the synthetic leather forms a cr...

Abstract

The invention discloses a method for manufacturing double-color synthetic leather. The method sequentially includes steps of preparing a wet base and forming dry adhesion layers; printing patterns and fixing colors; pressing grains; coating coatings on synthetic leather by a scraper on a coater; printing patterns and fixing colors by the aid of a printing machine, enabling a graining machine to rub the grains, winding the synthetic leather and forming a finished product to obtain the synthetic leather with downy feeling and a double-color effect. The method has the advantages that scraper equipment is introduced into a process for manufacturing the double-color leather, an imitation color of the synthetic leather is dark while a surface color of the synthetic leather is bright, and the synthetic leather is visual in double-color effect, clear and natural in grain and good in stereoscopic impression as compared with synthetic leather manufactured by an old process; the double-color synthetic leather is excellent in comprehensive physical performance.

Description

technical field [0001] The invention relates to a water-based polyurethane synthetic leather treatment agent and a method for making synthetic leather with the treatment agent. Background technique [0002] Traditional artificial leather has a single color, and the surface needs to be combined with various colors and patterns through printing and other subsequent processes. When it is used, the overall sense is rigid and dull, not dazzling and bright enough. At present, in order to make synthetic leather more environmentally friendly, in terms of synthetic leather, the application of water-based resins is now being vigorously promoted, and most of the existing technologies use finished products prepared by raw material suppliers of water-based treatment agents. The disadvantage of this material is its fluidity during use. Not good, the brightness distribution of the finished product is uneven, the brightness is not natural enough, and the crystal transparency is not obvious....
