Abstract

The invention relates to the field of sponge, in particular to environment-friendly degradable water-absorbing sponge with excellent mechanical performance. Preparation raw materials of the degradablewater-absorbing sponge include the following substances in parts by weight: 100 parts by weight of bacterial cellulose hydrogel block, 4-8 parts by weight of A additive, 3-6 parts by weight of B additive, 0.2-0.6 part by weight of formaldehyde, 0.35-0.75 part by weight of zinc oxide, 1.95-2.85 parts by weight of sodium fluorosilicate, 2.15-3.5 parts by weight of A accelerant, 0.35-0.55 part by weight of B accelerant and 5.5-8.5 parts by weight of additive. The substrate material (bacterial cellulose hydrogel block) used for the degradable water-absorbing sponge and the large numbers of components in the degradable water-absorbing sponge are all environment-friendly degradable materials, so that a prepared product is more environment-friendly.

Description

technical field [0001] The invention relates to the field of sponges, in particular to an environmentally friendly and degradable water-absorbing sponge with excellent mechanical properties. Background technique [0002] Sponge is a very common porous material with good water absorption, some of which have good elasticity, deformation recovery and other properties, and can be used to clean items or to produce some comfortable and soft seat cushions. [0003] Commonly used sponges are made from wood cellulose fibers or expanded plastic polymers. Alternatively, there are natural sponges made from spongy animals, and most natural sponges are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material, no obvious pores) and polyester. [0004] At present, the production cost of sponges in the market is positively correlated ...
