Abstract

The invention discloses polyurethane synthetic leather for decoration. The polyurethane synthetic leather sequentially comprises an anti-fouling layer, a printing layer, a dry method surface layer, amiddle layer, a foaming layer, a four-elasticity base cloth layer and a hot melt adhesive layer from outside to inside. According to the polyurethane synthetic leather for decoration, four-elasticitybase cloth is combined with a solvent-free process, environment-friendly semi-finished synthetic leather with a four-elasticity effect is made, the synthetic leather has a colorful appearance, a softtouch sense and daily antifouling performance through surface printing and antifouling treatment, the hot melt adhesive layer is compounded finally, and the polyurethane synthetic leather for decoration is prepared. The covering performance is excellent especially when the polyurethane synthetic leather is used as a refrigerator door plate, no wrinkle is generated at corners, the touch sense is soft, and grains are diversified.

Description

Technical field [0001] The invention belongs to the field of polyurethane materials, and specifically relates to a polyurethane synthetic leather for decoration and a preparation method thereof. Background technique [0002] Foreign countries divide home appliances into three categories: white home appliances, black home appliances and beige home appliances. White goods refer to products that can reduce people's labor intensity (such as washing machines, some kitchen appliances) and improve the living environment and improve material living standards (such as air conditioners, refrigerators, etc.). In the early days, most of these home appliances had a white appearance, hence the name. At present, mainland China is the world's largest white home appliance production base. With the improvement of people's living standards and material culture, people have put forward higher requirements for the appearance of home appliances. Now the appearance of traditional white goods is becomi...
