| titleOfInvention | Soft foaming sponge for seat and preparation method thereof |
| abstract | A preparation method of a soft foaming sponge for a seat comprises the following steps: step (1): mixing the isocyanate component and the toluene diisocyanate component according to a ratio, and uniformly stirring to obtain a black material; mixing polyether polyol, triethylene diamine solution, bis-dimethylamino ethyl ether solution, silicone oil, triethanolamine, a flame retardant and water according to a ratio, and uniformly stirring to obtain a white material; step (2): preheating a mould to enable the mould to be stable and constant at 50-55 ℃, placing all the seat back iron frame in the mould in advance, placing two ends of the iron frame in the mould completely, sealing the edge positions of the two ends of the iron frame placed in the mould, and then injecting black materials and white materials into the mould according to the proportion; and (3): after the black material and the white material are injected into the mold, the mold cover is covered, sealing rubber is filled between the mold and the mold cover, the clamp is locked, and the mold is sealed; and (4): and (3) controlling the pressure in the mould to be kept at 1.5Pa, foaming for 3-5 minutes, and then opening the mould to obtain the soft foaming sponge. |
