30min, after naturally cool to 70-75 DEG C of hot water is added in 45-50 DEG C of backward gained mixture, stirring makes mixture fully molten
Solution, sieving removes insoluble matter, in gained filtrate feeding spray dryer, dries gained particle and is made micro mist through micronizer,
Obtain final product nano-titanium dioxide modified poloxamer.
4. the aqueous abscess regulator suitable for synthetic leather according to claim 3, it is characterised in that：The pool Lip river is husky
Nurse, nano titanium oxide, PAMA, PDDA, rilanit special, polyvinyl alcohol contracting
The mass ratio of butyraldehyde and hot water is 15-20:3-5:0.5-1:0.3-0.5:0.1-0.2:0.05-0.1:50-80.
5. the aqueous abscess regulator suitable for synthetic leather according to claim 1 and 2, it is characterised in that the nanometer
Ceramic rubber powder is made up of the raw material of following parts by weight：Ceramic 3-5 parts, 2-3 parts of hydrogenated rosin pentaerythritol ester, pi-allyl
Glycidol ether 2-3 parts, 1-2 parts of hexamethylolmelamine pregnancy ether, 1-2 parts of C5 hydrogenated petroleum resins, microwax 0.5-1
Part, turpentine oil 0.5-1 part, maleic anhydride be grafted 0.05-0.1 parts of compatilizer, its specific preparation method is：To hydrogenated rosin season penta
Allyl glycidyl ether and C5 hydrogenated petroleum resins are added in four alcohol esters, and 115- is warming up to the programming rate of 5 DEG C/min
120 DEG C of insulation mixing 15-30min, add microwax and maleic anhydride grafting compatilizer, continue mixed in 115-120 DEG C of insulation
15-30min is closed, ceramic, hexamethylolmelamine are added after being cooled to 50-60 DEG C with the cooling rate of 10 DEG C/min
Pregnancy ether and turpentine oil, are sufficiently mixed, and gained mixture stands 1-2h in being transferred to -5-0 DEG C of environment, finally sends into nano-level grinder
In, nano ceramics rubber powder of the particle diameter in 30-50nm is obtained after being fully ground.
