Energy-saving and environment-friendly PU synthetic leather and production method thereof

Abstract

The invention discloses an energy-saving and environment-friendly PU synthetic leather which is prepared from the following raw materials in parts by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 4-8 parts of camellia seed meal, 1-2 parts of peanut shell, 1-2 parts of wheat straw, 1-2 parts of maize straw, 0.2-0.4 part of a silane coupling agent KH-550, 0.5-1 part of isocetyl stearate, 1-2 parts of oleum menthae, 3-6 parts of sodium carboxymethylcellulose, 0.5-1 part of aluminum chloride, 1-2 parts of white carbon black, 4-8 parts of mill base and 2-4 parts of a performance additive. The synthetic leather disclosed by the invention has good water-absorbing and ventilating properties, light weight, wear resistance, good simulation, energy saving and environment friendliness, and accords with the requirement of sustainable development.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to an energy-saving and environment-friendly 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 leathe...
