PU furniture leather and production method thereof

Abstract

The invention discloses a PU furniture leather which is prepared from the following raw materials in parts by weight: 80-100 parts of polyurethane resin, 80-100 parts of dimethylformamide, 1-2 parts of trehalose, 0.5-1 part of sodium alginate, 0.2-0.4 part of fenugreek gum, 2-4 parts of pine needle meal, 1-2 parts of lucerne meal, 3-6 parts of needle wood pulp cellulose, 2-4 parts of magnesium hydrate, 0.1-0.2 part of allicin, 5-10 parts of sodium carboxymethylcellulose, 0.1-0.3 part of petroleum sodium sulfonate, 0.01-0.02 part of sodium dichloroisocyanurate, 0.5-1 part of aluminum chloride, 4-8 parts of mill base and 4-6 parts of a performance additive. The PU furniture leather disclosed by the invention has the characteristics of good water absorbing and ventilating properties, simulated appearance, soft hand feel, flame retardance and fire resistance, safety, low toxicity and the like, and is suitable for making furniture.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a PU furniture 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 quality are hard to ...
