Abstract

The invention discloses a water-based velvet effect auxiliary agent applicable to synthetic leather, and relates to the technical field of synthetic leather functional auxiliary agents. The water-based velvet effect auxiliary agent applicable to the synthetic leather is prepared from the following raw materials in parts by weight: 15 to 20 parts of down fiber / polyvinylpyrrolidone, 5 to 10 parts of soybean protein fiber / poloxamer, 3 to 5 parts of microcrystalline cellulose / chitosan, 2 to 3 parts of cationic polyacrylamide, 2 to 3 parts of polyvinyl alcohol modified active argil, 1 to 2 parts of sodium carboxymethylcellulose, 0.5 to 1 part of polyethylene glycol 4000, 0.5 to 1 part of polyoxyethylene, 0.3 to 0.5 part of polyaluminium ferric sulfate chloride, 0.1 to 0.3 part of nanometer titanium dioxide powder, 0.05 to 0.1 part of stannous pyrophosphate and 100 to 150 part of water. The prepared water-based velvet effect auxiliary agent is added into waterborne polyurethane slurry and can be well blended and compatible with film forming raw materials, so that the processed and made synthetic leather has the characteristics of soft hand feeling, smooth velvet surface and uniform velvet hair; the hand feeling is similar to that of real leather; the use quality of a manufactured synthetic leather product is improved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of functional auxiliary agents for synthetic leather, in particular to a water-based suede auxiliary agent suitable for synthetic leather. [0003] Background technique: [0004] Synthetic leather is made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. It is widely used in making shoes, boots, bags and ball games. [0005] During the processing of synthetic leather, functional additives need to be added to enhance the feel, appearance quality and use quality of synthetic leather products. The cashmere additive is a special functional additive for synthetic leather, and its purpose is to give the synthetic leather a delicate cashmere feel and make it have a touch close to genuine leather...
