Color-changing synthetic leather and production technology thereof

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. 本发明所述种变色合成革，包括面层、变色层和发泡层，变色层原料按照重量份包括：聚氨酯100份，碳酸氢钙50-60份，热稳定剂1-3份，PVC色浆4-6份，应力变色革蜡粉1-2份，感温变色粉5-20份，石墨烯粉2-4份，银粉2-5份，纳米二氧化钛1-3份，本发明可以不仅可以随着温度变化，而且当踩在上面，或者制作成鞋，走路时也会产生变化，颜色多变，而且颜色鲜亮。
