A manufacturing method of sponge made from polyurethane foam containing silver nano particles and A sponge formed therefrom

摘要

The present invention is a polyurethane formed from a polyurethane foam which method and sponge containing the nanoparticles relates to a foamed sponge, the production method of the present invention is the addition of a blowing agent to prepare a polyurethane foam a plurality of bubbles formed therein, and then, according to the production method of the polyurethane foam polyurethane foam sponge was cut into a predetermined shape The blowing agent is characterized in that addition of further mixing the nano-colloid solution. The production method of the present invention is simple and economically not only be incorporated into the sponge inside the nanoparticles, the nanoparticles are present in the cell, so the durability is superior to the interior of the polyurethane foam to the frequent washing of the sponge is unique nanoparticles antibacterial effect can last for a long time.
