Preferably, the carboxymethyl modified starch is to be entered using sweet potato, mung bean, water caltrop, lotus rhizome or Chinese Water Chestnut Starch as raw material Row is carboxymethyl modified to be obtained.
Preferably, the oxidation modification starch is carried out by raw material of sweet potato, mung bean, water caltrop, lotus rhizome or Chinese Water Chestnut Starch Oxidation modification obtains.
Preferably, the anti-Formaldehyde as Additives is the mixture of graphene and nano titanium oxide, the graphene is with receiving The mass ratio of rice titanium dioxide is 1:10-10:1.
Preferably, the antibacterial and mouldproof auxiliary agent is graphene nano silver dispersion liquid, the graphene nano silver dispersion liquid The mass ratio of middle graphene and Nano Silver is 1:50-50:1.
Disappear preferably, the defoamer is mineral hydrocarbon defoamer and/or nonionic alkyl copolymer Infusion.
Preferably, the solubilizer is the table that PEG-40, PEG-60, PEG-80 rilanit special etc. has solubilising power Face activating agent.
Compared with prior art, the advantages and positive effects of the present invention are,
1st, it is of the invention compared with traditional glutinous rice glue, graphene composition is with the addition of, using the light transmittance of graphene, makes its work For photocatalysis carrier, light-catalyzed reaction and electronics conduction efficiency are substantially increased.It is improved with the compound of nano titanium oxide The photocatalytic activity of photocatalyst, add the decomposition efficiency and persistence of formaldehyde.The big specific surface area of graphene and spy simultaneously Different two-dimensional slice structure, the contact area of anti-biotic material and bacterium can be strengthened, so as to improve antibacterial and mouldproof efficiency, reach efficient Lasting antibacterial and mouldproof effect.And the addition of graphene, improve the adhesive property of glutinous rice glue.
