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 a high-performance PU sofa leather which is produced from the following raw materials in parts by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 0.5-1 part of liquid paraffin, 0.2-0.4 part of cetostearyl alcohol polyether-25, 0.4-0.6 part of lauryl sodium sulfate, 0.2-0.4 part of tween-80, 2-4 parts of gelatin, 5-10 parts of sodium carboxymethylcellulose, 0.5-1 part of aluminum chloride, 0.5-1 part of methyl salicylate, 0.5-1 part of nanometer titania, 4-8 parts of mill base and 6-8 parts of a performance additive. The high-performance PU sofa leather disclosed by the invention has the characteristics of good stretchability, wear resistance, good water absorbing and ventilating properties, simulated appearance, and good hand feel; the comfort and the simulation are effectively improved, and the performance is relatively close to that of natural leather.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a high-performance PU sofa leather and a production method thereof. Background technique [0002] PU synthetic leather is a polyurethane elastomer, similar in structure to natural leather, and has the advantages of good appearance and texture, strong mechanical properties, low price, and convenient processing. , At present, it has replaced a large number of natural leather with insufficient resources. However, some properties of PU synthetic leather are far inferior to that of 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 its water absorption and breathability are limited. Sex, comfort and quality are difficult to improve. [0003] Sodium carboxymethyl cellulose hydrogel is a functional polymer material that has a special adsorption effect on w...
