Embodiment 1

[0021] A color-changing synthetic leather of the present invention comprises a surface layer, a color-changing layer and a foaming layer, and the raw materials of the color-changing layer include by weight: 100 parts of polyurethane, 55 parts of calcium bicarbonate, 2 parts of heat stabilizer, and 5 parts of PVC color paste , 1.5 parts of stress-changing leather wax powder, 7 parts of thermochromic powder, 3 parts of graphene powder, 3 parts of silver powder, 2 parts of nano-titanium dioxide, 4 parts of protein powder, 2 parts of sodium octyl succinate sulfonate, 2 parts 30% zinc succinate, graphene powder speeds up the discoloration, protein powder, sodium octyl succinate and zinc succinate make the color of artificial leather more delicate, and silver powder makes the color brighter.

[0022] The surface layer is PU surface layer.

[0023] The foam layer includes 92 parts of PVC resin, 28 parts of plasticizer, 3 parts of stabilizer, 3 parts of silver powder and 5 parts of fo...

Embodiment 2

[0030] The technical solution of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated, and the difference is that:

[0031] The color-changing synthetic leather of the present invention comprises a surface layer, a color-changing layer and a foaming layer, and the raw materials of the color-changing layer include by weight: 100 parts of polyurethane, 58 parts of calcium bicarbonate, 2.5 parts of heat stabilizer, and 5.5 parts of PVC color paste , 1.8 parts of stress-changing leather wax powder, 12 parts of thermochromic powder, 3.5 parts of graphene powder, 4 parts of silver powder, 2.5 parts of nano-titanium dioxide, 5 parts of protein powder, 2.8 parts of sodium octyl succinate sulfonate, 2.8 parts parts of zinc succinate.

[0032] The surface layer is PU surface layer.

[0033] The foam layer includes 97 parts of PVC resin, 32 parts of plasticizer, 3.5 parts of stabilizer, 4 parts of silver powder and 5.5 parts of foaming...

Abstract

A color-changing synthetic leather comprises a surface layer, a color changing layer and a foam layer, and raw materials of the color changing layer comprise, by weight, 100 parts of polyurethane, 50-60 parts of calcium hydrogen carbonate, 1-3 parts of a heat stabilizer, 4-6 parts of a PVC color paste, 1-2 parts of stress color-changing leather wax powder, 5-20 parts of thermochromic powder, 2-4 parts of graphene powder, 2-5 parts of silver powder and 1-3 parts of nanometer titanium dioxide. The color of the color-changing synthetic leather changes with temperature, and the color-changing synthetic leather changes when being stepped or changes during walking after being made into shoes, so the color of the color-changing synthetic leather changes, and is bright.

Description

technical field [0001] The invention relates to a synthetic leather, in particular to a color-changing synthetic leather and a production process thereof. Background technique [0002] Leather is widely used in various fields including automobile industry, sofa, etc. Leather usually includes natural leather and synthetic leather, wherein, synthetic leather is cheaper and easier to mass-produce than natural leather. [0003] Synthetic leather is a plastic product that looks and feels like leather and can be used instead of it. There are mainly three types of PVC synthetic leather, PU synthetic leather and PU synthetic leather. In the field of synthetic leather, most of them use non-woven fabrics of 100% chemical synthetic fibers (polyester, nylon) as the base, coated with synthetic resin and various plastics. [0004] At present, bringing more changes to leather products is one of the factors that the industry focuses on research and development at this stage. The existing c...
