Abstract
The invention discloses a method for binding zinc chloride to a colloidal material. 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 zinc chloride being bound in colloidal materials.
Background technology
Inanimate matter coated metal oxide particles, have the suppression effect of very high photocatalytic activity when coordinating cosmetic preparation
Really, but it is difficult to destroy the water proofing property cosmetic preparation made up being coupled to oil-based cosmetic material, w/o decentralized cosmetic preparation or sweat
In occasion under, have in hydrophobic substrates dispersion insufficient it is impossible to give full play to above-mentioned excellent powder characteristics etc.
Improper.The metal nanoparticle of liquid suspension has some shortcomings in catalytic action, and it includes recycling nano particle and urges
The difficulty of agent.
Catalyst is fixed on carrier and is possibly realized so as to recycle catalyst via simple filtration.However,
The synthesis (it includes injecting carrier with metal nanoparticle) of fixing catalyst is probably very time-consuming.For example, palladium chtalyst
The reaction (heck reaction) for carbon-carbon bond formation be multiduty industrial synthesis tool.It includes being soaked with acid chloride (ii)
Stain carrier (silica of such as precipitation), is dried, with hydrogen or other suitable reducing agent reduction.
Two kinds of well-known methods that metal is combined on porous support are dipping (sometimes referred to as " just wet impregnations
(incipient wetness) " technology) and be directly synthesized via sol-gel technique.Dipping includes adopting solid porous carrier
And metal salt solution is added to described carrier.Metal salt solution flow into (intercalate) by the structure of porous carrier and
Form surface deposits when being dried.During the slaine of reduction deposition, metallic particles has the surface migrating to porous carrier
On trend and have to pass through loose structure to disperse.Due to less active surface area, this migration lead to sintering and
Comprehensive decline of catalysis activity.
In recent years, have excellent, safe using UV-preventing ability more than the cosmetic preparation of UV-preventing ability
Inorganic system UV-preventing material.As inorganic system UV-preventing material, generally use the oxidation of the metals such as titanium oxide, zinc oxide
The powder of thing.
But, these metal oxide particles are intactly coupled under the occasion in cosmetic preparation it is known that existing
So some problems, use feeling is deteriorated, or, the photocatalytic activity that metal oxide particle has produces not to human body skin
Good impact it is therefore necessary to carry out some coating to metal oxide particle.Particularly preferably it is used in light-catalyzed reaction and be difficult to send out
The inorganic substances of biochemical change are coated to.That UV-preventing ability above-mentioned will be widely used as excellent, safe
The titanium oxide of inorganic system UV-preventing material, the metal oxide particle such as zinc oxide is intactly coupled in cosmetic preparation
Occasion under, there is use feeling during cosmetic and be deteriorated, or, the photocatalytic activity that metal oxide particle has is to human body
The problems such as have harmful effect, therefore, carries out now surface and is coated to the inorganic substances without Photocatalytic activity power.With oxidation
The metal oxide particle that aluminium, silica etc. are coated to commercially is sold, but does not still know and can meet by coating simultaneously
Product come good use feeling when suppressing photocatalytic activity and to be coupled in cosmetic preparation.
