Efficient bacteriostatic PU synthetic leather and producing method thereof

Abstract

Efficient bacteriostatic PU synthetic leather is disclosed. The synthetic leather is prepared from following raw materials by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 5-10 parts of sodium carboxymethyl cellulose, 1-2 parts of coconut oil, 1-2 parts of castor oil, 0.5-1 part of disodium EDTA, 0.2-0.5 part of sodium dodecylpoly(oxyethylene) sulfate, 0.2-0.5 part of a honeysuckle flower extract, 0.5-1 part of water-soluble lanolin, 1-2 parts of chitosan, 0.5-1 part of aluminium chloride, 1-2 parts of seaweed meal, 0.2-0.5 part of benzethonium chloride, 3-6 parts of color paste and 2-4 parts of modification additives. The synthetic leather has good water absorption and air permeability performance and comfort, and is capable of effectively inhibiting growth and reproduction of bacteria on surfaces of the synthetic leather, providing a clean and sanitary environment and benefiting human health maintaining.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a high-efficiency antibacterial 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, co...

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
