Abstract

The invention discloses a high elasticity sponge and a production method, and the sponge comprises the following raw materials by weight: 87-93 parts of trimethylolpropane polyether, 33-40 parts of toluene diisocynate, 10-15 parts of E-12 epoxy resin, 10-12 parts of nano sepiolite powder, 0.7-0.9 parts of stannous octoate, 0.2-0.4 parts of zinc acetate, 14-18 parts of dimethicone, 2-3 parts of modifier and 5.0-6.5 parts of water. The high elasticity resistance sponge has the characteristics of softness, elasticity and water resistance. The nano sepiolite powder has excellent wettability, acid resistance, high temperature resistance and corrosion resistance, E-12 epoxy resin has a certain high elasticity and bonding performance, structural connection in the sponge is enhanced, and memory reduction ability of the sponge can be also enhanced.

Description

technical field [0001] The invention relates to a preparation method of a sponge, in particular to a high elastic sponge and a preparation method thereof. Background technique [0002] Sponge products have gradually become popular in people's lives, including seats, sofas, mattresses and other household items made of sponge. In addition to the household items made of sponges, people also use sponges as cleaning utensils, such as cleaning household with sponge products, cleaning dishes with sponge products, bathing with sponge products, etc. [0003] The existing sponge production method has a single process, and the product performance index cannot fully meet the needs of the market, so it is urgently required to conduct research from different aspects. Contents of the invention [0004] The object of the present invention is to provide a kind of high elasticity sponge and preparation method thereof. [0005] In order to achieve the above object, the present invention ad...
