Abstract

The invention relates to the field of sponges, in particular to an environment-friendly degradable high-elasticity sponge with an excellent mechanical property. The degradable high-elasticity sponge comprises the following preparation raw materials in parts by weight: 100 parts of a composite sponge substrate, 3-5.5 parts of an additive A, 4-9 parts of an additive B, 0.5-1.1 parts of zinc oxide, 1.7-2.55 parts of sodium fluosilicate, 2.35-4.5 parts of an accelerant A and 1.1-2.35 parts of an accelerant B. According to the degradable high-elasticity sponge, the used substrate material and plenty of the raw materials are green and environment-friendly degradable materials, so that the prepared products are more green and environment-friendly and have favorable biocompatibility; the preparation process and the using process are harmless to human bodies; and the sponge has favorable chemical stability and excellent mechanical property, and is extremely excellent in elasticity.

Description

technical field [0001] The invention relates to the field of sponges, in particular to an environmentally friendly and degradable high-elastic 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 wit...
