Abstract

The invention belongs to the technical field of high polymers and in particular relates to soft and strong-elasticity sponge and a preparation method thereof. The soft and strong-elasticity sponge isprepared from the following raw materials: toluene diisocyanate, polyether polyol, polymer polyol, dichloromethane, an ammonia compound, silicone oil, stannous octoate and a flame retardant. The preparation method of the soft and strong-elasticity sponge comprises the following steps: (1) carrying out primary polymerization; (2) carrying out secondary polymerization; (3) curing and molding. The soft and strong-elasticity sponge provided by the invention has a fine hand feeling and an oily feeling, and has relatively strong resilience; the soft and strong-elasticity sponge is not easy to deformafter being used for a long time, can be used for safety measure or related articles for children and realizes buffering, heat-insulation, filling, sound isolation, sound absorption, curing and beautifying effects; the preparation method provided by the invention is simple and easy to operate and the prepared soft and strong-elasticity sponge has high density and good consistency.

Description

technical field [0001] The invention belongs to the technical field of polymers, and in particular relates to a soft and strong elastic sponge and a preparation method thereof. Background technique [0002] In recent years, children's products have paid more and more attention to high quality. At present, the traditional sponge used for children's safety measures or related products does not feel good, and it is easy to deform after being permanent. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a soft and strong elastic sponge, which has a delicate and oily feel, strong resilience, and is not easily deformed after long-term use; another aspect of the present invention The purpose is to provide a preparation method of a soft and strong elastic sponge, the preparation method is simple and easy to operate, and the prepared soft and strong elastic sponge has good con...
