Mould-proof sponge material and method for preparing same

Abstract

The invention discloses an anti-mold sponge material and a preparation method thereof. The above-mentioned anti-mold sponge material is made of the following components in parts by weight: 80-100 parts of polyvinyl alcohol aqueous solution, tristyrylphenol polyoxyethylene ether 11-18 parts, 2-3 parts of sodium alginate, 1-2 parts of sorbitol fatty acid ester, 1-2 parts of glutaraldehyde, 1-2 parts of polyvinyl butyral, dipentyl succinic acid sulfonate 0.2-0.8 parts of sodium bicarbonate, 0.1-0.2 parts of sodium bicarbonate, 0.1-0.2 parts of sodium silicate, 0.01-0.03 parts of azobisisobutyronitrile and 0.01-0.02 parts of carbon black. The invention also provides a preparation method of the mildew-proof sponge material.

Description

technical field

[0001] The invention belongs to the field of sponge materials, in particular to a mildew-proof sponge material and a preparation method thereof. Background technique

[0002] Sponge, a porous material with good water absorption, is often used as cushioning material and cleaning items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers.

[0003] The existing preparation methods of polyvinyl alcohol sponge include: foaming method with pore forming agent, foaming method with foaming agent, and mechanical foaming method. Among them, the pore-forming agent foaming method is to add a pore-forming agent (starch) to the polyvinyl alcohol solution first, and then use a large amount of water to wash off the starch after the polyvinyl alcohol is solidified and formed. The sponge product produced by this process is difficult to clean the starch completely, and the residual starch will breed mold and cause product deterioration, which limi...
