Technical Field

The utility model relates to a sponge technical field especially relates to a high fire-retardant environment-friendly sponge for fire control fire prevention shoes.

Background

Sponges, which are porous materials, have good water absorption and can be used to clean articles. Sponges commonly used by people are made of wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made of sponge animals, and most of the natural sponges are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, low density polyether (non-absorbent sponge), polyvinyl alcohol (superabsorbent material, no significant air holes) and polyester, respectively.

Common sponge on the market today is mostly chemical raw materials foaming and forms, easy burning, and the sponge of being applied to fire prevention shoes then needs good fire behaviour, consequently, in order to improve the fire behaviour of sponge, can add some fire-retardant auxiliaries in the foaming, reduce the bubble aperture simultaneously, reach fire-retardant purpose, this gas permeability that just causes the sponge easily slightly reduces, has reduced the travelling comfort.
