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 imitated PU (polyurethane) synthetic leather, made from the following materials according to parts by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 1-2 parts of a soluble starch, 1-2 parts of galactomannan, 1-2 parts of peanut oil, 1-2 parts of flaxseed oil, 1-2 parts of serpeggiante powder, 0.5-1 part of turkey red oil, 0.1-0.3 part of polylysine, 0.1-0.2 part of sodium lauroyl sarcosine, 0.2-0.4 part of star anise oil, 5-10 parts of sodium carboxymethyl cellulose, 0.5-1 part of aluminum chloride, 4-8 parts of color paste, and 6-8 parts of a modifying aid; the synthetic leather has good water absorption and breathability and imitated appearance and handle, comfort and imitation of the PU synthetic leather are improved effectively, and the properties of the synthetic leather are closer to those of natural leather.

Description

technical field [0001] The invention belongs to the field of synthetic leather production, and in particular relates to a simulated 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,...
