Description
Technical field
The present invention relates to mica powder technical field, more particularly to a kind of preparation side of high-purity mica powder of wet process used for cosmetic
Method.
Background technology
Mica powder is a kind of nonmetallic mineral, containing Multiple components, wherein mainly there is SiO2, content typically 49% or so,
Al2O3Content is 30% or so；Mica powder has good elasticity, toughness, insulating properties, high temperature resistant, acid and alkali-resistance, corrosion-resistant, attachment
The characteristic such as power is strong.Mica powder is a kind of excellent additive, is widely used in electrical equipment, welding rod, rubber, plastics, papermaking, oil
The industries such as paint, coating, pigment, ceramics, cosmetics, building material, purposes is extremely extensive.Mica powder is due to its unique pearly-lustre effect
Really, crystal transparency, silky luster and soft and smooth texture, make it have splendid compatibility and patch skin, mica powder conduct with skin
The preferred high-grade silty raw material of cosmetic industry, is widely used in the crowds such as muffin, sweet powder, eye shadow, foundation emulsion, rouge, sweet powder
It is multi-field.But existing dry ground muscovite mica preparation technology destructible mica flake and seamed edge, gained mica powder feel is coarse, light
Damp degree is low, and dispersiveness and tack are poor, and pearl effect is not obvious.Moreover, simple dry process mica powder, it is impossible to have
Impurity that the removal mica powder itself of effect contains and variegated, gained mica powder purity and whiteness be not high, applied to superior cosmetics
And pearlescent pigment field effect is not good.Based on above statement, the present invention proposes a kind of high-purity mica powder of wet process used for cosmetic
Preparation method.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of high-purity used for cosmetic proposed
The preparation method of mica powder of wet process.
A kind of preparation method of high-purity mica powder of wet process used for cosmetic, comprises the following steps：
S1, selected high-quality mica ore, and mica ore is added in hydraulic fracture machine, coarse crushing to particle diameter is
1~5mm, filters to obtain mica corase meal A；
S2, the mica corase meal A of gained in step S1 is added in flotation device, added after flotation agent and water, 2~4h of enrichment,
With 10000~12000r/min rotating speed 8~15min of high speed centrifugation, go to obtain mica powder B after the removal of impurity；
S3, the mica powder B of gained in step S2 added water into solid content for 28~53%, be made after suspension and be added to colloid
In grinder, after 1~2h of wet-milling, lapping liquid C is obtained；
S4, by step S3 gained lapping liquid C be added to concentration be 13~33% hydrochloric acid solution in, be heated to 82~98 DEG C
0.8~1.5h of insulated and stirred, is then cooled to 65~75 DEG C afterwards, and it is 51~64%, insulated and stirred to add ethanol solution to alcohol content
After 1~2h, 4~8h, isolated sediment D are stood；
S5, by step S4 gained sediment D through rotating speed for 10000~12000r/min supercentrifuge dehydration after, put
In being dried in 100~180 DEG C of baking oven to constant weight, then break up and produce required mica powder.
It is preferred that, the flotation agent in the step S2 is one kind in kerosene, diesel oil or pine-tree oil.
It is preferred that, the addition of flotation agent is the 55~89% of mica corase meal A total amounts in the step S2.
It is preferred that, the addition of the step S2 reclaimed waters is 4.3~6.8 times of mica corase meal A total amounts.
It is preferred that, the mass ratio of lapping liquid C and hydrochloric acid solution is 1~1.6 in the step S4:9.5~15.
The preparation method of a kind of high-purity mica powder of wet process used for cosmetic proposed by the present invention, by high-quality mica ore
After being handled through hydraulic fracture, add to suspend in flotation device and go the removal of impurity, wet ground then is carried out to mica powder, to improve mica
Acid solution and organic solvent are utilized respectively after the precision of powder, wet ground impurity elimination and discoloration processing are carried out to mica powder, then taken off
Dried after water, break up and produce, preparation method proposed by the present invention is simple, it is low to prepare cost, and mica powder is entered using whole wet method
Row processing, using water and chemicals and gentle mechanism, makes after mica layer stratification opens, and is made that scale is very thin, seamed edge is clear
Clear, radius-thickness ratio is big, the suitable mica powder of particle diameter, compared to dry process, and the present invention is gentle, environmental protection, effectively avoids dry method
Handle destructible mica flake and the problem of seamed edge, it is to avoid dust pollution, gained mica powder feel is soft and smooth, good luster, disperse
Property and tack it is good, pearl effect substantially, and with high purity and whiteness, can be widely applied to superior cosmetics, height
Level coating, pearlescent mica pigment and engineering plastics field, are worthy to be popularized.
