Abstract

The invention provides gel remembering sponge and a preparation method thereof. The gel remembering sponge is formed by mixing and foaming the following raw materials by weight: 55 to 65 parts of slow rebound polyether polyol, 20 to 30 parts of soft-foam polyether polyol, 10 to 20 parts of polymer polyol, 5 parts of silica-gel powder, and 30 to 40 parts of toluene diisocyanate. The gel remembering sponge adopts an original sponge formula, so as to greatly improve the heat-transfer capability of the gel remembering sponge, and ensure that a person can feel cool when being in touch with the gel remembering sponge, the original slow rebound resilience of the gel remembering sponge is not reduced, and the comprehensive performance of the gel remembering sponge is improved finally. Therefore, the market competitiveness of the gel remembering sponge is obviously higher than those of the conventional like products.

Description

technical field [0001] The invention relates to the technical field of sponge products, in particular to a gel memory sponge and a preparation method thereof. Background technique [0002] Sponge products are widely used in furniture products, and gel memory foam with slow rebound effect is used as filling material in middle and high-end furniture. However, the current sponge products have the problem of poor heat transfer effect, which makes filling Sponge furniture is not suitable for use in hot summer weather, which also affects the popularity of furniture filled with sponge materials. At present, the improvement of the heat transfer effect of sponge products will cause a serious loss of the characteristics of the sponge product itself, such as gel memory foam. It is said that while its heat transfer ability is improved, its slow rebound effect and the characteristics of the sponge itself will be destroyed, thus affecting product performance. [0003] Therefore, prio...
