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

Sound-absorbing 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, 2-4 parts of vinyl acetate-acrylic emulsion, 1-2 parts of castor oil, 0.1-0.2 part of glycerol monocaprylate, 0.2-0.5 part of lecithin, 4-6 parts of diatomite, 2-4 parts of rice husk, 0.2-0.4 part of tea tree oil, 0.2-0.4 part of nonylphenol polyoxyethylene ether, 5-10 parts of sodium carboxymethyl cellulose, 0.5-1 part of potassium sodium tartrate, 0.5-1 part of aluminium chloride, 4-8 parts of color paste, and 3-5 parts of modification auxiliary agents. The synthetic leather has sound-absorbing and noise-reducing functions, has good water absorption and air permeability performance and emulational texture, and is suitable for applications in indoor decoration.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to sound-absorbing 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 qualit...
