Problems solved by technology

Generally, antibacterial agents can be added to improve the antibacterial performance. The commonly used antibacterial agents can be divided into two categories: inorganic antibacterial agents and organic antibacterial agents. The former has higher heat resistance, but the cost is high, and the latter has higher sterilization efficiency. , the amount of addition is small, but there are disadvantages such as poor heat resistance and low safety

Abstract

The invention provides a mold-proof sponge material and a preparation method thereof. The method comprises the following steps: firstly, preparing a first material by adopting modified resin, surfactant and foaming agent; preparing a second material by adopting glutaraldehyde, imidazoline biguanide sulfate, liquid curing agent and isooctyl sulfhydrate; slowly adding the preheated first material into the second material and preparing into a mixture; and foaming, thereby acquiring the mold-proof sponge material. The foaming is sufficient, the elasticity is excellent, the molecular chains of glutaraldehyde and imidazoline biguanide sulfate are mutually intertwined and penetrate into the holes of the sponge material and a mold-proof effect is achieved. The sponge material provided by the invention has excellent mechanical property and anti-mold property.

Description

technical field [0001] The invention relates to the technical field of sponge materials, in particular to a mildew-resistant sponge material and a preparation method thereof. Background technique [0002] Sponge has good water absorption and is a porous material, usually used for cushioning materials or cleaning items. Commonly used sponges are made of wood cellulose fibers or expanded plastic polymers, and there are a few natural sponges made of sponge animals that can be used for body cleaning or painting. In addition, there are three types of synthetic sponges, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material, no obvious pores) and polyester. [0003] Under suitable temperature and humidity conditions, microorganisms (bacteria and mold) will proliferate in the pores of the sponge, and the secretion of the mold will cause the biodegradation of the sponge material. Higher requirements are put forward for the hygienic perfor...
