News on December 13, 2023, according to the announcement of the State Intellectual Property Office, Anhui Anli Material Technology Co., Ltd. applied for a project called "A super-soft embossed polyurethane synthetic leather and its preparation method and application" ", Publication No. CN117211086A, application date is September 2023.
The patent abstract shows that the invention relates to a super-soft embossed polyurethane synthetic leather and its preparation method and application. The super-soft embossed polyurethane synthetic leather includes a surface layer, a middle layer, a fitting layer and a base fabric layer arranged in sequence from the outside to the inside. The surface layer is made of surface layer polyurethane slurry, and the surface layer polyurethane slurry is The material is prepared from the following components by weight: 100 parts of polycarbon solvent-based polyurethane A, 2-4 parts of reactive silicone additives. Among them, the softening point of the polycarbon solvent-based polyurethane A is 150°C-180°C, and the reactive silicone additive is a single-ended dihydroxy silicone mixture. The surface layer of the present invention uses polycarbon solvent-based polyurethane A with a softening point of 150-180°C and is added with reactive silicone additives. In conjunction with the low-temperature embossing process, the pattern can be shaped under low-temperature embossing. The reactive silicone additives It can react with polycarbon solvent-based polyurethane A to introduce silicone components into the polyurethane system. The resulting polyurethane synthetic leather has a strong velvety appearance, a soft and plump hand feel, and a three-dimensional and full pattern.
