Description
Technical field
The present invention relates to the nano titanium oxide that a kind of liquid phase siliceous deposits is modified, belong to powder body material technical field.
Background technology
Because nano titanium oxide has good anti-ultraviolet property, weatherability, chemical resistance, heat resistance, light
The features such as catalytic, heat endurance, are widely used in the industries such as pigment, rubber, plastics, papermaking, while also as photocatalysis
Agent, photoelectric cell, ultraviolet light screener etc. are widely used.Not surface treated nano titanium oxide surface can be higher, and
Polar group hydroxyl is contained on surface, therefore, and nano titanium oxide easily produces reunion because of polarity absorption or moisture absorption.
The nano titanium oxide of non-surface modification is added in high molecular polymer as additive prepares composite
When, there is scattered uneven technical problem, so that the combination property of its nano composite material prepared is poor, in application
On be limited by very large.Therefore, it is necessary to carry out surface modification to nano titanium oxide, its dispersive property is improved.
The content of the invention
It is an object of the invention to for nano titanium oxide is easily reunited in the prior art the problem of and a kind of liquid phase is provided
The nano titanium oxide that siliceous deposits is modified, the nano titanium oxide has preferably dispersiveness and stability.
Realize technical scheme that the object of the invention uses for：The nano titanium oxide that a kind of liquid phase siliceous deposits is modified, it is described
Silica be nano titanium oxide quality 18%~30%.
The preparation process of deposition silica in nano titanium oxide surface of the present invention is as follows：
Step 1）：By nano titanic oxide impregnation in the n-hexane solvent of methyl-silicone oil, stir, mixing is made
Liquid；
Step 2）：By step 1）Obtained mixed liquor is evaporated, and is put in baking oven and is dried, and is subsequently placed in Muffle
High-temperature roasting is carried out in stove, methyl-silicone oil is changed into silica, that is, surface deposition, which is made, the nano-silica of silica
Change titanium.
In step 1）In, described nano titanium oxide and the mass ratio of methyl-silicone oil are（0.5~1）：1, described first
The mass volume ratio of base silicone oil and n-hexane solvent is 1g：3mL.
In step 2）In, described carry out high-temperature roasting, its roasting condition is：Under excess oxygen, with 10 DEG C/min's
Speed is warming up to 500 DEG C, keeps 2h.
The advantage of the invention is that：1st, the present invention carries out siliceous deposits modification on the surface of nano titanium oxide, substantially reduces
The surface of nano titanium oxide can, so as to improve the dispersiveness and stability of nano titanium oxide.2nd, raw material of the invention
Valency is low, and technique is simple, beneficial to industrialized production, is highly suitable for cosmetics, nano-function textile, functional plastics and coating
Deng field.
