Abstract

The invention discloses a skinning solvent-free PU leather for a massage chair. The skinning solvent-free PU leather successively comprises a constituent cloth layer, an adhesive layer, a PU foaming layer and a finishing layer. The PU foaming layer comprises the following raw materials by weight: 95-105 parts of PU resin, 86-95 parts of an eco-solvent, 8-11 parts of calcium carbonate, 0.12 part ofa catalyst and 0.5-5 parts of a color paste. The skinning solvent-free PU leather for the massage chair is simple in composition and friendly to environment, substantially improves the use performance of skinning leather for the massage chair in virtue of the excellent physical and chemical characteristics, and can realize the industrial upgrading of the skinning leather industry.

Description

technical field [0001] The invention relates to the field of artificial leather, in particular to a solvent-free PU leather for massage chairs and a preparation method thereof. Background technique [0002] The special performance and feel of leather make it synonymous with "high-end" in the decoration of bags, clothing, shoes, vehicles and furniture, and has been fully affirmed by the market. Many, incalculable. Due to the long production cycle and limited quantity of natural leather, artificial leather has become its substitute, and there are many types of artificial leather, and high-grade artificial leather is even more expensive than genuine leather. [0003] PU artificial leather is the epidermis of polyurethane composition, which is suitable for various decorations instead of genuine leather, with good shaping effect and bright surface. PU foam material is one of the PU materials with a special structure, which has unique physical properties, good heat insulation, s...
