Problems solved by technology

However, some properties of PU synthetic leather are far inferior to natural leather. For example, natural leather has good water absorption and air permeability, while the nature of PU synthetic leather itself makes it easy to form a dense film, and the water absorption and air permeability are limited. The simulation of synthetic leather Performance, comfort and quality are difficult to improve

Abstract

The invention discloses an anti-mildew PU synthetic leather which is produced from the following raw materials in parts by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 1-2 parts of soluble starch, 1-2 parts of galactomannan, 1-2 parts of peanut oil, 1-2 parts of linseed oil, 1-2 parts of muyu-stone powder, 0.5-1 part of Turkey red oil, 0.1-0.3 part of polylysine, 0.1-0.2 part of sodium lauroyl sarcosinate, 0.2-0.4 part of star anise oil, 5-10 parts of sodium carboxymethylcellulose, 0.5-1 part of aluminum chloride, 4-8 parts of mill base and 6-8 parts of a performance additive. The anti-mildew PU synthetic leather disclosed by the invention has good water absorbing and ventilating properties, simulated appearance, soft hand feel, and mildew preventing property.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a mildew-resistant PU synthetic leather and a production method thereof. Background technique [0002] PU synthetic leather belongs to polyurethane elastomer, which is similar to natural leather in structure, and has the advantages of good appearance texture, strong mechanical properties, low price, and convenient processing. It has a wide range of applications and a large number of types, and is an ideal material to replace natural leather. , At present, it has largely replaced natural leather with insufficient resources. However, some properties of PU synthetic leather are far inferior to natural leather. For example, natural leather has good water absorption and air permeability, while the nature of PU synthetic leather itself makes it easy to form a dense film, and the water absorption and air permeability are limited. The simulation of synthetic leather Sex, comfort and qua...
