Abstract

The invention discloses a preparation method of solvent-free sofa furniture microfiber synthetic leather, and is characterized in that an environmental-protection type polyether polymeric carbon composite type polyurethane resin is selected as a dry surface layer and a middle layer, a solvent-free layer is a foaming adhesive layer, a microfiber cloth base cloth pasted by a whole dry process and having good hand feeling and high chemical properties is selected for preparing the environmental-protection type sofa furniture leather having the excellent properties of strong real leather effect feeling, three-dimensional and full pattern, abrasion resistance, scratch resistance, hydrolysis resistance and the like; the solvent-free foaming layer is two-liquid type double-compound polyurethane and is composed of an isocyanate A component and a polyether polyol B component. The prepared solvent-free environmental-protection type sofa furniture leather has the advantages of simple leather preparation process, high efficiency and environmental protection, also has the characteristics of strong real leather effect feeling, three-dimensional and full pattern, full and soft hand feeling, wear resistance (wyzenbeek 400 thousand times), scratch resistance, hydrolysis resistance (8 years) and other high physical properties.

Description

technical field [0001] The invention relates to the technical field of preparation of ecological and environment-friendly polyurethane synthetic leather, in particular to a preparation method of solvent-free ultrafiber synthetic leather for sofa furniture. Background technique [0002] With the development of the national economy, people's living standards and consumption levels have been continuously improved, and the concept of environmental protection has become more and more in-depth. People have higher and higher requirements for the quality and environmental protection of products used in daily life. Although the current leather products have the advantages of comfortable hand feeling, good elasticity, strong sensuality, and good durability, due to the limited natural leather resources, they are far from meeting people's consumption needs. In this market situation, environmentally friendly high-physical polyurethane synthetic leather products provide consumers with a g...
