The method comprises the following steps: mixing 10 g of zinc chloride with 50 ml of silicic acid solution to form a mixture; adding 10 ml of 0.3 M sodium hydroxide solution into the mixture; heating for 0.4 hour at the temperature of 50 DEG C; reducing bound metallic particles with a reducing agent to form a product.
Description
Technical field
The present invention relates to a kind of method be bonded to by zinc chloride in colloidal materials.
Background technology
Inanimate matter coated metal oxide particles, there is when coordinating cosmetic preparation the inhibition of very high photocatalytic activity, but be coupled to oil-based cosmetic material, w/o decentralized cosmetic preparation or sweat be difficult to destroy make up water proofing property cosmetic preparation in occasion under, the dispersion had in hydrophobic substrates is insufficient, can not give full play to the improper of above-mentioned excellent powder characteristics etc.The metal nanoparticle of liquid suspension has some shortcomings in catalytic action, and it comprises the difficulty recycling nanoparticle catalyst.
Catalyst is fixed on and carrier makes recycle catalyst become possibility via simple filtration.But the synthesis of fixing catalyst (it comprise inject carrier with metal nanoparticle) may be very consuming time.Such as, the reaction for carbon-carbon bond formation (Heck reaction) of palladium chtalyst is multiduty industrial synthesis tool.It comprises with acid chloride (II) impregnated carrier (silicon dioxide such as precipitated), dry, the reducing agent reduction be applicable to hydrogen or other.
Flood melts combine two kinds of well-known methods on porous support (sometimes referred to as " just wet impregnation (incipient wetness) " technology) and directly synthesize via sol-gel technique.Dipping comprises employing solid porous carrier and metal salt solution is added to described carrier.Metal salt solution flows into (intercalate) by the structure of porous carrier and forms surface deposits when drying.During the slaine of reduction deposition, metallic particles has the trend that migrates on the surface of porous carrier and has to pass through loose structure to disperse.Due to less active surface area, this migration causes comprehensive decline of sintering and catalytic activity.
In recent years, there is the inorganic system UV-preventing material that cosmetic preparation many uses UV-preventing ability is excellent, safety is high of UV-preventing ability.As inorganic system UV-preventing material, generally use the powder of the metal-oxide such as titanium oxide, zinc oxide.
But, under these metal oxide particles being intactly coupled to the occasion in cosmetic preparation, knownly there are like this some problems, use sense is deteriorated, or, the photocatalytic activity that metal oxide particle has exerts an adverse impact to human body skin, therefore must carry out some to metal oxide particle and be coated to.Particularly preferably be used in light-catalyzed reaction the inorganic substances being difficult to occur chemical change to be coated to.Under the occasion that the metal oxide particle such as titanium oxide, zinc oxide being widely used as the inorganic system UV-preventing material that above-mentioned that UV-preventing ability is excellent, safety is high is intactly coupled in cosmetic preparation, use sense when there is cosmetic is deteriorated, or, the photocatalytic activity that metal oxide particle has has the problems such as harmful effect to human body, therefore, carry out surface-coated with the inorganic substances without Photocatalytic activity power now.The metal oxide particle coating with aluminium oxide, silicon oxide etc. is commercially sold, but does not still know the goods that can simultaneously meet by being coated to good use sense when suppressing photocatalytic activity and be coupled in cosmetic preparation.
