The invention belongs to technical field of nano material, and in particular to a kind of nano-titanium dioxide/nano zinc oxide composite powder material is made by following steps: 1) zinc acetate and butyl titanate being dissolved in dehydrated alcohol, stirred evenly, and mixed solution is made；2) water bath method will be carried out in mixed solution obtained, is then put in baking oven and is dried, places into and carries out high-temperature roasting in Muffle furnace, and composite granule is made；3) by composite granule obtained and stearic acid, carboxymethyl cellulose, hexamethylene mixing and ball milling, nano-titanium dioxide/nano zinc oxide composite powder material is obtained.After the present invention organically combines nano zine oxide and nano-titanium dioxide, the UVA and UVB in solar ultraviolet can be effectively shielded.
Description
Technical field
The invention belongs to technical field of nano material, and in particular to a kind of nano-titanium dioxide/nano zinc oxide compound powder
Body material.
Background technique
The ultraviolet light that solar radiation comes out can be divided by its wavelength: wavelength is the long wave ultraviolet of 320~400nm
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 the UVA for accounting for solar ultraviolet 91% will not cause fierce reaction as UVB, penetration is strong, 35~
50% can reach corium, keep the fibr tissue of intradermal injured, lead to shouting pain, cutis laxa and tanned, be to cause skin photoage
And one of the main reason for cutaneum carcinoma.UVC due to being absorbed substantially in atmosphere outer layer.
Nano zine oxide and nano-titanium dioxide are two kinds of important and widely used inorganic UV sun-screening agents, but its is right
The screening ability of UVA and UVB be it is discrepant, nano-titanium dioxide obstruct UVB effect it is very good, but to the shielding of UVA imitate
Fruit is not good enough；Nano zine oxide is undesirable to the shield effectiveness of UVB, but it obstructs UVA effect and is better than nano-titanium dioxide.
In order to effectively obstruct UVA and UVB, reaches overall protected purpose, need thus comprehensive in sunscreen cosmetic
Close the characteristic for utilizing nano zine oxide and nano-titanium dioxide.Therefore, it develops one kind and has both nano-titanium dioxide and nano oxidized
The composite powder material of zinc advantage is research hotspot.

Preferably, in step 2, the high-temperature roasting condition are as follows: under excess oxygen, be warming up to 500 DEG C with 5 DEG C/min
Roasting 1~3 hour.
Preferably, in step 3), Ball-milling Time is 1~3 hour.
Compared with prior art, the advantageous effects of technical solution of the present invention are:
1, nano zine oxide of the invention/nano-titanium dioxide composite powder material can effectively shield after organically combining
Cover the UVA and UVB in solar ultraviolet.
2, nano zine oxide of the invention/nano-titanium dioxide composite powder material, through stearic acid, carboxymethyl cellulose
Ball-milling reaction, changes the surface nature of composite powder material, and nano zine oxide/nano-titanium dioxide composite powder material has
