Silica gel sponge material and preparation method thereof

Abstract

The invention discloses a silica gel sponge material which comprises polyurethane sponge and a silica gel solution, and a functional auxiliary agent is added into the silica gel solution. The preparation method comprises the following steps: S1, designing the size and thickness of polyurethane sponge, the flowability of a silica gel solution and the proportion of a functional auxiliary agent according to product requirements; s2, according to design requirements, cutting the polyurethane sponge into sheets with corresponding thicknesses by using cutting equipment; s3, preparing a silica gel solution with corresponding flowability according to design requirements, and adding a functional auxiliary agent in a corresponding proportion into the silica gel solution; and S4, adding a silica gel solution on the polyurethane sponge sheet. According to the silica gel sponge material and the preparation method thereof, the silica gel solution is added on the polyurethane sponge, so that the polyurethane sponge has the effect of multiply increasing the tearing strength, meanwhile, the oxidation resistance and the high temperature resistance are improved, and the silica gel can also inhibit the generation of bacteria.
