The preparation method of grain protein/Nano particle composite material in situ: at first grain protein is joined weight percent concentration and be in 10~25% the ammoniacal liquor, be made into weight percent concentration and be 5~20% grain protein solution, under agitation condition, drip weight percent concentration then and be 10~40% aqueous chloride solution, reaction 0.5~1h, transfer pH to 6~7, centrifugation, lower floor's slurries are with deionized water wash and centrifugation, repeat 5~8 times, dry, ground 100 mesh sieves, add softening agent again, softening agent weight is 10~100% of grain protein weight, place mould, mold pressing 10~30min under 100~140 ℃ of temperature obtains grain protein/Nano particle composite material in situ goods.
Described grain protein is gluten powder, rice protein powder, wheat gliadin, hordein, zein or kafirin.Nanoparticle is nano-sized magnesium hydroxide particle or nano-aluminum hydroxide particle.Nanoparticle is that in-situ hydrolysis produced metal chloride in the aqueous solution of grain protein.Softening agent is glycol ether, triglycol, 1,4-butyleneglycol, 1,3 butylene glycol, 2,3-butyleneglycol, glycerine, 1,2,4-trihydroxybutane, 1,2,3-hexanetriol or 1,2,6-hexanetriol.Metal chloride is magnesium chloride or aluminum chloride.
Advantage of the present invention is:
1) adopting the ammonia solution of grain protein is reaction medium, make magnesium chloride or aluminum chloride hydrolysis generate magnesium hydroxide or aluminum hydroxyl nano particle, its surface hydroxyl can form hydrogen bond action with amido on the protein molecule chain, carboxyl etc., thereby suppresses the reunion of nanoparticle;
2) residual amino molecule can volatilize in drying or mold process voluntarily after the muriate hydrolysis, does not need special removal;
3) grain protein/Nano particle composite material in situ has excellent moulding processability, can adopt compression molding to prepare composite product;
4) safety non-toxic of grain protein/Nano particle composite material in situ has biodegradation character.
Embodiment
The preparation of grain protein/nanoparticle original position mixture is a key of the present invention.The present invention adopts alkaline solution to dissolve grain protein first, and the protein soln of compounding high concentration drips magnesium chloride or liquor alumini chloridi, and in-situ hydrolysis generates magnesium hydroxide or aluminum hydroxyl nano particle.Form dispersion liquid or suspension if grain protein does not dissolve, nanoparticle disperses inhomogeneous in solution and occurs reuniting.In magnesium chloride or aluminum chloride hydrolytic process, should stir incessantly, to promote the homodisperse of nanoparticle in protein soln.Can add an amount of softening agent in the solution after hydrolysis is finished, and it is uniformly dispersed when stirring, and obtains grain protein/nanoparticle original position mixture after 50~80 ℃ of dryings are removed moisture.
Above-mentioned grain protein/nanoparticle original position mixture can adopt the conventional direct compression molding of vulcanizing press, and molding temperature is advisable with 100~140 ℃.In this temperature range, protein molecule forms network structure by intermolecular disulfide bond.
Grain protein/Nano particle composite material in situ that the present invention obtained is implemented crosslinked by disulfide linkage between protein molecule.Under field conditions (factors), these disulfide linkage can rupture, and protein molecule can be hydrolyzed to amino acid.Thereby the grain protein/Nano particle composite material in situ that is obtained can be degraded fully, and its resistates magnesium hydroxide or aluminium hydroxide are harmless fully to environment.
