Problems solved by technology

The synergistic effect produced by adjusting the formula and the different proportions of various flame retardants can improve the flame retardant properties of sponge products and reduce the impact of flame retardants on the physical properties of sponge products, but it is still an unsolved problem. During long-term use, the migration and precipitation of flame retardants, and the performance of soft polyurethane foam products have changed.

Abstract

The invention discloses a flame-retardant type sponge with an anti-acarid function and a preparation method thereof. Perforated polyurethane is subjected to coating treatment, so that the flame-retardant property and the anti-acarid property are greatly improved; and an impregnated perforated sponge product has the properties of good flame-retardant effect, small smoke density, no toxicity of smoke and the like, the flame-retardant grade can achieve UL94V-0 grade, the anti-acarid effect is good, and the repellant ratio achieves above 70%.

Description

technical field [0001] The invention belongs to the technical field of sponge products, and in particular relates to a flame-retardant sponge with anti-mite function and a preparation method thereof. Background technique [0002] A high-density sponge is a sponge with a weight of more than 45 kilograms per cubic meter of sponge. High-density sponge has the characteristics of absorbing external force, delicate, soft, and comfortable. It is mainly used in automobiles, furniture, health care, toys and other industries, and can meet various market needs. [0003] Therefore, it is necessary to design a new design. The present invention uses the upper and lower multi-layer structures to clamp the flame-retardant ball to prevent the accidental rupture of the flame-retardant ball. It improves the fire-proof and flame-retardant performance of the sponge, and improves the overall safety of the sponge. [0004] Traditional flame retardant materials widely use halogen-containing polym...
