The invention relates to the technical field of
polyurethane materials, in particular to a light
polyurethane shoe material for sports shoes and a preparation process thereof, and the light
polyurethane shoe material comprises the following components: 40-60 parts by weight of polyether
polyol, 20-40 parts by weight of
hexamethylene diisocyanate, 20-40 parts by weight of N, N-
dimethylformamide, 1-5 parts by weight of a
coupling agent, 1-5 parts by weight of an
antioxidant, 1-5 parts The invention relates to a
flame-retardant and
flame-retardant material which is prepared from the following components in parts by weight: 0.5-1.5 parts of N, N-dimethyl
cyclohexylamine, 5-15 parts of modified p-toluenesulfonhydrazide microcapsules, 1-3 parts of a nucleating agent, 0.5-2 parts of
zinc dialkyl dithiophosphate, 0.5-2 parts of
phenyl salicylate and 0.5-2 parts of polyoxyethylene
sorbitan monooleate. The
aryl halide can improve the
thermal decomposition temperature of p-toluenesulfonyl
hydrazide, so that the p-toluenesulfonyl
hydrazide is not easy to decompose in advance under a high-temperature
processing condition, and the foaming process can be accurately controlled. Due to the fact that the
fatty acid can reduce the
surface tension of the
system, gas can form tiny bubble nucleuses in the
system more easily, the number of
bubble nucleation sites is increased, a more fine and uniform bubble structure can be generated, and the buffering performance and the overall quality of the shoe material are improved.
