Abstract

The invention belongs to the technical field of polyurethane sponge. The invention discloses polyether type polyurethane sponge with a flame-retardant function. The polyether type polyurethane spongeis prepared from the following raw materials: first polyether polyol, second polyether polyol, third polyether polyol, a first catalyst, a second catalyst, silicone oil, rubber, water, a composite foaming agent, MDI isocyanate, and the like, wherein the composite foaming agent is prepared from surface-coated sodium bicarbonate, surface-coated ammonium carbonate and azodicarbonamide; the surface-coated sodium bicarbonate is prepared by coating the surface of sodium bicarbonate with an organic silicon quaternary ammonium salt antibacterial agent; the surface-coated ammonium carbonate is preparedby coating the surface of ammonium carbonate with potassium perfluorobutanesulfonate. The polyether type polyurethane sponge provided by the invention has slow resilience, is moderate in hardness andhas a good flame-retardant effect; special antibacterial treatment is carried out on pores of the polyether type polyurethane sponge, so that the problem that harmful microorganisms such as bacteriaeasily grow and enrich in the pores of the sponge can be solved.

Description

technical field [0001] The invention relates to the technical field of polyurethane sponge, in particular to a polyether polyurethane sponge with flame-retardant function. Background technique [0002] Sponge generally refers to all foaming materials, and foamed products of resin, rubber, and plastic are called sponges. Polyurethane sponge is foamed polyurethane material. Polyurethane not only has the elasticity of rubber, but also has the strength of plastic and excellent processing performance, and can be used to prepare polyurethane slow rebound foam (soft polyurethane foam). [0003] Flexible polyurethane foam can be divided into polyester type soft foam and polyether type soft foam according to the polyol raw material used. Polyether polyurethane is an open cell structure with the characteristics of temperature-sensitive decompression, and can also be called a temperature-sensitive decompression material. [0004] As a polymer organic foam material, the flammability ...
