Anti-ultraviolet PU synthetic leather and producing method thereof

Abstract

Anti-ultraviolet 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 dimethyl formamide, 6-8 parts of nanometer zinc oxide, 1-2 parts of nanometer silicon dioxide, 1-2 parts of polyethylene glycol, 5-10 parts of sodium carboxymethyl cellulose, 2-4 parts of glycerin, 0.4-0.6 part of jojoba oil, 0.1-0.3 part of wheat germ oil, 0.5-1 part of aluminium chloride, 0.5-1 part of dimethicone, 0.1-0.3 part of sodium polyacrylate, 0.2-0.5 part of sodium cocoyl glycinate, 3-6 parts of color paste and 1-2 parts of a modification auxiliary agent. The synthetic leather has characteristics of good anti-ultraviolet functions, high wear resistance, soft and emulational texture, good water absorptivity and good air permeability, and is suitable for the fields of garments, and the like.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to an anti-ultraviolet 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 qu...

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
