Description
Technical field
The invention belongs to technical field of nano material, and in particular to a kind of nano titanium oxide/nano zinc oxide compound powder
The preparation method of body material.
Background technology
The ultraviolet that solar radiation comes out can be divided into by its wavelength：Wavelength is 320~400nm long wave ultraviolet
UVA, the short wave ultraviolet UVC that the ultraviolet B radiation UVB and wavelength that wavelength is 290~320nm are 200~290nm.Research knot
Fruit shows：Although fierce reaction will not be caused as UVB by accounting for the UVA of solar ultraviolet 91%, penetration is strong, its 35~
50% can reach corium, make the fibr tissue of intradermal injured, cause shouting pain, cutis laxa and tanned, be to cause skin photoage
And one of the main reason for cutaneum carcinoma.UVC due to having been absorbed substantially in air outer layer.
Nano zine oxide and nano titanium oxide are two kinds of important and widely used inorganic UV sun-screening agents, but its is right
UVA and UVB screening ability is discrepant, and nano titanium oxide barrier UVB effect is very good, but the shielding effect to UVA
Fruit is not good enough；Nano zine oxide is undesirable to UVB shield effectiveness, but it obstructs UVA effects and is better than nano titanium oxide.
In order to effectively obstruct UVA and UVB, reach overall protected purpose, needed for this comprehensive in sun care preparations
Close the characteristic using nano zine oxide and nano titanium oxide.Therefore, how to design one kind and have nano titanium oxide and nanometer concurrently
The composite powder material of zinc oxide advantage is study hotspot.
The content of the invention
It is an object of the invention to provide a kind of preparation side of nano titanium oxide/nano zinc oxide composite powder material
Method.
In order to realize the purpose of the present invention, the technical solution adopted by the present invention is as follows：
A kind of preparation method of nano titanium oxide/nano zinc oxide composite powder material, it is as follows that it includes step：
Step 1）：Zinc acetate and butyl titanate are dissolved in absolute ethyl alcohol, stirred, mixed solution is made；
Step 2）：By step 1）Water bath method is carried out in obtained mixed solution, is then put in baking oven and is dried, then
It is put into Muffle furnace and carries out high-temperature roasting, composite granule is made；
Step 3）：By step 2）Obtained composite granule and stearic acid, carboxymethyl cellulose, hexamethylene mixing and ball milling 1~3
Hour.
Preferably, step 1）In, the amount ratio of the material of described zinc acetate and butyl titanate is 1：（1~3）, described vinegar
The mass volume ratio 1g of sour zinc and absolute ethyl alcohol：10mL.
Preferably, step 2）In, the high-temperature roasting condition is：Under excess oxygen, 500 DEG C are warming up to 5 DEG C/min
Roasting 1~3 hour.
Preferably, step 3）In, described composite granule and stearic acid, carboxymethyl cellulose, the quality volume of cyclohexane
Than for 1g：（0.5~0.8）g：（0.05~0.1）g：（5~10）mL.
Compared with prior art, the advantageous effects of technical solution of the present invention are：
1st, nano zine oxide/nano titanium oxide composite powder material preparation method of the invention, nano titanium oxide and
The UVA and UVB in solar ultraviolet can be effectively shielded after the combination of nano zine oxide.
2nd, nano zine oxide/nano titanium oxide composite powder material prepared by the present invention, it is fine through stearic acid, carboxymethyl
The ball-milling reaction of element is tieed up, changes the surface nature of composite powder material, nano zine oxide/nano titanium oxide composite granule material
Material has preferably dispersive property.
3rd, raw material of the invention is easy to get, and cost is low, and reaction is easily controlled.
