Abstract

The invention relates to a solvent-free foaming material. The solvent-free foaming material is prepared from, by weight, 95-105 parts of solvent-free polyurethane resin, 1.5-2.5 parts of water, 0.8-1.2 parts of flatting agent and 5-10 parts of bridging agent. The invention further relates to artificial leather. The solvent-free foaming material has the advantages of being environmentally friendly, free of smell and good in oil and high temperature resistance.

Description

technical field [0001] The invention relates to leather foaming technology, in particular to a solvent-free foaming material and artificial leather. Background technique [0002] In the prior art, foaming materials are often used in the foaming layer of artificial leather to prepare artificial leather. The formula of the existing foaming material is (parts by weight): 100 parts of polyvinyl chloride resin, 70-100 parts of dioctyl phthalate, 50-60 parts of filler, 2-3 parts of auxiliary agent and foaming agent 3-5 servings. The foaming material of above-mentioned formula is after carrying out foaming reaction, because phthalic anhydride and 2-ethylhexanol react to generate azodicarbonamide, and azodicarbonamide is unfriendly to environment; Simultaneously, phthalic anhydride Formic anhydride is called phthalic anhydride, which is a white scale crystal with a melting point of 130 and a boiling point of 284.5. It can sublime below the boiling point and produce a special smell...
