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 mildewprevention sponge material. A preparation methodcomprises the steps of firstly preparingmodified resin, a surfactant and a foaming agent into a first material, preparingglutaraldehyde, imidazoline bismuth sulphate, a liquid curing agent and Isooctyl mercaptopropionate into a second material, adding the preheated first material slowly into the second material to forma mixture, and finally foaming to obtain the mildewprevention sponge material; the foaming is sufficient, the sponge material has good resilience performance, and molecular chains of the glutaraldehyde and the imidazoline bismuth sulphate are intertwined with each other and inserted between pores of the sponge material to synergistically act as a mildew prevention effect. The sponge material hasboth good mechanical properties and mildew prevention performance.

Description

[0001] This application is a divisional application, the application number of the original application is 201710784377.4, the application date is September 4, 2017, and the title of the invention is "An anti-mildew sponge material and its preparation method". technical field [0002] The invention relates to the technical field of sponge materials, in particular to a mold-proof sponge material. Background technique [0003] 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. [0004] Under suitable temperature and humidity conditions, ...
