Abstract

The invention relates to the field of shoe materials, and in particular relates to a method for preparing memory sponge. The method mainly comprises the following steps: premixing, uniformly mixing at high speed, milky-whitening, foaming and aging. The memory sponge prepared by using the method is poor in temperature sensitivity, so that the hardness does not change along with the change of temperature or is slightly changed. Therefore, after the memory sponge which is prepared by using the method is made into a shoe, the wearing space of the shoe is not affected, and thus not only is the manufacturing cost of the shoe not increased, but also the shoe is relatively comfortable to wear for wearers.

Description

technical field [0001] The invention relates to a formula used in the field of shoe materials, in particular to a preparation method of memory foam; the memory foam is mainly used for making insoles. Background technique [0002] In the field of shoe materials, there are many materials used for making, and memory foam is one of them. At present, there are memory foams used for shoe materials on the market, but the existing memory foams are highly sensitive to temperature, and will undergo strong soft and hard changes with temperature changes, which cannot be changed without temperature changes. or purposes with little change. This seriously affects the quality of shoe material products. For example, the internal space of shoes will become smaller due to the hardening of memory foam in winter, and on the contrary, the internal space will become larger due to softening in summer. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, an...
