Abstract

The invention discloses an environment-friendly breathable TPU synthetic leather and a preparation method thereof. The environment-friendly breathable TPU synthetic leather comprises a decorative surface layer, a TPU surface layer, an adhesive layer and a base cloth layer. The decorative surface layer is coated on The treatment agent on the upper surface of the TPU surface layer is generated, and the TPU surface layer is combined with the base cloth layer through the adhesive layer. The components and parts by weight of the TPU surface layer are: 30 to 95 parts by weight of TPU particles; 3 to 95 parts by weight of the flame retardant 25 parts by weight; 2-15 parts by weight of pigment; 0-5 parts by weight of light stabilizer; 0-5 parts by weight of anti-scratch agent; 0-20 parts by weight of filler. The adhesive is a water-based polyurethane adhesive; the surface treatment agent is a water-based polyurethane surface treatment agent. Adopting the preparation method of extrusion casting, shaping first, then compounding, and negative pressure embossing, the products are environmentally friendly, non-toxic, low-odor, low-VOC, clear in structure, soft in hand, scratch-resistant, wear-resistant, hydrolysis-resistant, genuine leather Strong features.

Description

technical field [0001] The invention relates to an environment-friendly synthetic leather, in particular to an environment-friendly breathable TPU synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather is an important industrial material, mainly used in clothing, shoes and hats, sofas, luggage, sporting goods, etc. It is a substitute for animal leather. The development of my country's synthetic leather started in the 1980s and rose rapidly in the 1990s. At present, my country's synthetic leather has accounted for more than 70% of the world's total output. In the existing synthetic leather industry, traditional synthetic leather products mainly include PVC (polyvinyl chloride) synthetic leather and PU (polyurethane) synthetic leather. A large amount of toxic and harmful chemical ingredients such as chlorine (halogen group) are used in the synthesis of PVC synthetic leather. Elements), plasticizers (phthalates), heavy metals (lead,...
