8. a kind of preparation method of high-strength mattress material according to claim 1-7, which is characterized in that including
Following steps:
S1: polyolefin, carbon fiber, chain extender, foaming agent, foam stabilizer, catalyst are stirred by weight, the rate of stirring
For 500-600r/min, time 30-60min；
S2: being added toluene di-isocyanate(TDI) in the mixed liquor obtained to step S1, be stirred, and stands reaction foaming, is formed poly-
Urethane foam；
S3: by graft polyether, triethylene diamine and surfactant mixed at high speed, mixing speed 800-1000r/min, time
For 20-30min, polyurethane foam is then added and is uniformly mixed, obtains polyurethane mixture；
S4: graphene, which is placed in deionized water, obtains evenly dispersed graphene aqueous solution after ultrasonic disperse, by silica gas
Gel pours into graphene aqueous solution, and mechanical stirring to pulpous state, spray drying disperses graphene in dioxy at 80-100 DEG C
Graphene poromerics is formed in SiClx aeroge micropore；
S5: being added polyurethane mixture into graphene poromerics, and it is 8-9 that sodium bicarbonate pH value is added in whipping process,
1-2h is reacted at room temperature, is then placed in confined chamber and is toasted, baking temperature is 80-85 DEG C, time 5-10h, is taken out in room temperature
High-intensitive mattress material can be obtained in interior standing 12-24h.
