Kind.
A kind of manufacturing method for the fire-retardant slow-recovery sponge for not adding fire retardant, the constituent content according to claim 1 weigh
First polyether polyol, the second polyether polyol, low resilience silicone oil, catalyst, water in component A are added to blender by component
In, stirring 1min~2min is allowed to mix, and the three/portion for first adding in parts by weight in 12~40 parts of polyurea polylol carries out
It is stirred, it is quiet to after 5-10min, adding three points of parts by weight in 12~40 parts of polyurea polylol after mixing 1-2min
Two parts be stirred mixing, after mixing 1-2min, add B component and pour into the component A just stirred evenly, stir after 3-7s from
By foaming, curing obtains fire-retardant slow-recovery sponge at normal temperatures after foaming.Polyurea polylol is added in two times, just for the first time
After step mixing, heat release is mixed, object to be mixed replys room temperature after standing, and will not be put substantially when adding polyurea polylol mixing again
Heat makes the first polyether polyol, the second polyether polyol, the property of polyurea polylol more stablize, gives full play to its fire-retardant effect
With.
The present invention has significant technique effect as a result of above technical scheme：By controlling component A and B component
Respective amount obtains slow-recovery sponge using full water foamed process, slow-rebound polyether polyol used, isocyanates,
Catalyst does corresponding adjustment as the case may be, and the oxygen index (OI) of foam can be significantly improved by polyurea polylol, effectively reduces
Smoke amount during foam combustion, though with the significant oxygen index (OI) for pressing down cigarette effect and avoiding conventional flame retardant that from effectively improving foam,
But smoke amount during to foam combustion adversely affects, and the slow-recovery sponge of gained does not add any fire retardant in formula,
With regard to that can reach flame retardant effect, oxygen index (OI) is all more than 25, and free foaming density does not reach 30kg/m after density is low3, full water foamed, object
It is excellent to manage index, the rebound time stretches up to more than 60s, tear, collapses and be up to state standards.
