Preparation method of sponge formed by embedding of porous network material and polyvinyl alcohol porous foamed sponge

Abstract

The invention provides a preparation method of sponge formed by embedding of porous network material and polyvinyl alcohol porous foamed sponge. The making steps include that: firstly polyvinyl alcohol aqueous solution is prepared and warmed, pore-forming agent, antifoaming agent, cross linker and crosslink catalyst are respectively added in to the polyvinyl alcohol aqueous solution, rapid stirring is carried out to obtain polyvinyl alcohol mixed solution, then steel wire gauze material is placed in a container; then the polyvinyl alcohol mixed solution is poured into the container, pressurizing equipment is adopted to pressurize the steel wire gauze, bubble exhaust and air exhaust are carried out, and pressurizing and bubble exhaust are carried out again, the container is sealed and secondary air exhaust is carried out, the container is placed in a thermostat for warming and curing, the products are cleaned, sliced and packed into sponge for cleaning, not only cleaning and decontamination are easy and cleaning agent remaining efficiency is high but also handfeel is good, no scrap drops, no germ grows, and the sponge is environmentally friendly and sanitary.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a production process of combining hard and soft materials into a sponge. Background technique [0002] Commonly used cleaning materials are generally foam sponges or hot-melt fiber artificial pickle cloths (commonly known as scouring pads), or stainless steel wire balls and nylon nets. These cleaning tools have insufficient cleaning agent retention performance in use. defects, and the rough surface is easy to scratch the surface of the cleaning object. In addition, although soft sponges and other materials have the ability to retain detergent, they are limited by the characteristics of the material itself, lacking the ability to clean and decontaminate, and cannot achieve the expected effect; Possess decontamination ability, but the ability to retain detergent is not enough, the detergent contained in it will be washed away immediately at the moment of flushing, and for some dea...

[0002] Commonly used cleaning materials are generally foam sponges or hot-melt fiber artificial pickle cloths (commonly known as scouring pads), or stainless steel wire balls and nylon nets. These cleaning tools have insufficient cleaning agent retention performance in use. defects, and the rough surface is easy to scratch the surface of the cleaning object

In addition, although soft sponges and other materials have the ability to retain detergent, they are limited by the characteristics of the material itself, lacking the ability to clean and decontaminate, and cannot achieve the expected effect; Possess decontamination ability, but the ability to retain detergent is not enough, the detergent contained in it will be washed away immediately at the moment of flushing, and for some dead corners that need to be cleaned, the same effect is limited because it cannot be deformed to reach the corner
