Object.
The present invention is using the principle of above-mentioned raw materials：Using polyether polyol and polymer polyatomic alcohol as main foaming
Raw material, elasticity is good, porosity is high, good permeability after polyether polyol foaming, after polymer polyatomic alcohol is combined with polyether polyol
The sponge foamed under the facilitation of water and foaming agent, the density filled because in are promoted with toughness, and porosity increases,
Calcium carbonate in raw material is particles filled in the gap of sponge fiber in foaming process, to make its hole keep firm
With it is uniform, while it is modified using the auxiliary agent that epoxy resin, calcium zinc stabilizer and isoprene are mixed to get, asphalt mixtures modified by epoxy resin
Fat integrally promotes the hardness and toughness that sponge is made, and calcium zinc stabilizer makes each raw material uniformly combine before foaming, and foaming is made to be made
Sponge hole it is firm, continuous matter is smooth, and adaptability of the sponge to environment can also be further promoted after being combined with calcium carbonate, is allowed to
Fast light, heat-resisting, isoprene can strengthen the continuous matter of sponge, make the pore size formed in wherein foaming process and distribution
Uniform and stabilized structure, to keep sponge more pressure-resistant and resilience on the basis of not reducing porosity with gas permeability good；Wine
Stone acid antimony potassium makes each raw material in sponge mutually consolidate combination, promotes the combination of calcium carbonate and sponge fiber, and sponge obtained is made to exist
It is not scattered during long-term use not scaling-off yet；Catalyst promotes the fine and closely woven property of the percent opening and stomata of sponge, improves elasticity；
Dispersant makes sponge and raw material be more easy to be uniformly mixed by stirring technique before foamable reaction；Surfactant promotes each original of sponge
The associativity of material, make after being combined with potassium antimony tartrate, catalyst each raw material in foaming process at the uniform velocity, stablize and closely knot
It closes, to form the special sponge of sofa that density is big, hardness is high, resilience is good.
As an optimization, the calcium carbonate is nanoscale, and particle size is 80 nanometers hereinafter, the particle size of calcium carbonate is got over
