Abstract

The invention discloses a method for producing high-visibility polyurethane artificial leather, comprising the following steps: blending a surface course sizing agent, wherein the surface course sizing agent is prepared from the raw materials comprising polycarbonate type polyurethane, dimethyl fomamide, a waterproof agent, a modified polysiloxane defoamer, an antiager and an aqueous fluorescence pigment; fully mixing and blending the blended surface course sizing agent; filtering by utilizing a 200-mesh sieve; defoaming by utilizing a vacuum defoaming machine for standby; blending an adhesive coating sizing agent, wherein the coating sizing agent is prepared the raw materials comprising polyurethane, dimethyl fomamide, a ultraviolet light absorber, an accelerant and a cross linking agent; fully mixing and blending the blended coating sizing agent; filtering by utilizing the 200-mesh sieve for standby; and coating. In the method, the existing formula is regulated, produced products completely conform to the requirements of EN471 high-visibility materials, and the aspects such as weather resistance, hydrolysis resistance, waterproof vapor permeability and the like all exceed the similar products in the market.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing polyurethane artificial leather, in particular to a method for manufacturing highly visible polyurethane artificial leather. 【Background technique】 [0002] With the development of society and the improvement of people's living standards, the society pays more and more attention to various safety protection, and the demand for various high-visibility materials is increasing. Fluorescent materials are bright in color and have good visual effects. They are widely used in luggage and clothing fabrics, and are also deeply loved by consumers. Especially in Europe and the United States, there is a great demand for highly visible protective clothing with warning signs. However, the existing fluorescent fabrics have poor light fastness and easy fading on the surface, which cannot meet the requirements of EN471 or ANSI / ISEA107 standards, resulting in reduced performance and seriously affecting the service l...
