Description
Technical field
The present invention relates to acidification, be specifically related to the mica after a kind of acidifying.
Background technology
Chinese sericite Resource management is large, distribution is also wide, but is worth the less of exploitation.According to the origin of ore deposit of sericite, generally sericite mineral deposit is divided into sheet lithotype sericite mica ore bed, porphyry alteration type sericite mineral deposit, volcanics alteration type sericite mineral deposit, secondary quartz lithotype illite sericite mineral deposit, clay lithotype sericite illite mineral deposit, wherein main maximum with sheet lithotype sericite mica ore value of exploiting and utilizing, because the mica feature of such sericite mica ore is the most obvious.
The chemical constitution of sericite, structure, structure are close with kaolin, and have again some characteristic of clay mineral, namely in water medium and organic solvent, dispersion suspension is good, and look white grain is thin, toughness etc.Therefore, sericite has the various features of mica mineral and clay minerals concurrently.
In order to improve the application quality of mica, need to carry out acidification to mica.
Summary of the invention
The object of the invention is to overcome weak point in prior art, the mica after a kind of acidifying is provided.
Mica batching after acidifying is made up of sericite, attapulgite clay, magnesium oxide, sulfuric acid, quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate.
The production method of the mica after acidifying: by abrasive dust in the mica batching input grinding machine after acidifying, the meal after abrasive dust is the mica after acidifying.
Mica has good elasticity, toughness, insulativity, high temperature resistant, acid and alkali-resistance, corrosion-resistant, the characteristic such as strong adhesion and satin luster, sericite has high resistance, excellent insulating material and fire-retardant filler, sericite significantly can change the series of physical modulus of material, form or change the visco-elasticity of material, this kind of material is absorbing vibrational energy, weakening shock wave and sound wave expeditiously, be used to preparation noise elimination, sound insulation, damping coating, the present invention selects the sericite after pulverizing, particle fineness≤0.5 millimeter of sericite.
Attapulgite clay has unique layer chain-like structure feature, and crystal is needle-like, threadiness or fiber collection shape.Attapulgite clay has unique dispersion, high temperature resistant, anti-good colloidal property and the higher adsorptive power such as saline and alkaline, and has certain plasticity-and cohesive force, and the present invention selects particle fineness≤5 millimeter of attapulgite clay.
Magnesium oxide has the general character of basic oxide, belongs to gelling material, can improve the colloidal property of mica.
Sulfuric acid select concentration be 98% the vitriol oil.
Quick dissolved sodium silicate is white powder material, can rapid solution in water, have that cohesive force is strong, intensity is higher, acid resistance, good heat resistance, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, external form divide cotton-shaped, particulate state, Powdered three kinds; Nonpoisonous and tasteless, particulate state can be dissolved in 80--90 DEG C of water, pulverous other powders pre-dispersed after can dissolve at normal temperatures.There is good viscosity, polymerizability, cohesiveness and water-retentivity.
Vltra tears has thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, excellent film-forming properties and the feature such as resistance to enzymatic, dispersiveness and cohesiveness widely.
Sodium carbonate has the general character and the thermostability of salt, soluble in water, and its aqueous solution is alkalescence, in the present invention for adjusting the mica pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the mica batching after acidifying is made up of following component by weight percentage: the mica work in-process 90 ~ 98% after acidifying, quick dissolved sodium silicate 0.1 ~ 5%, polyvinyl alcohol 0.1 ~ 5%, Vltra tears 0.01 ~ 3% and sodium carbonate 0 ~ 3%.
The production method of the mica 2, after acidifying: by abrasive dust in the mica batching input grinding machine after acidifying, particle fineness≤0.074 millimeter, the meal after abrasive dust is the mica finished product after acidifying.
3, the half-finished production method of the mica after acidifying: stir in the stirrer (1) input of the batching of mica mixture operated, then dilute sulphuric acid is slowly added in mica mixture carry out acidification; (2), by the mica mixture after acidification, be mica platelets by twin rollers extruding, thickness≤3 millimeter of mica platelets; (3) mica platelets is transported to roasting in rotary type stoving oven, roasting time is 1 ~ 3 hour, and maturing temperature controls at 300 ~ 400 DEG C, mica platelets water content≤2% after roasting, mica platelets after roasting is the mica work in-process after acidifying, and PCm is weight percentage.
4, the batching of mica platelets is made up of following component by weight percentage: mica mixture 75 ~ 95% and dilute sulphuric acid 5 ~ 25%.
5, the batching of mica mixture is made up of following component by weight percentage: sericite 68 ~ 92%, attapulgite clay 5 ~ 30% and magnesium oxide 0.1 ~ 3%.
6, the batching of dilute sulphuric acid is made up of following component by weight percentage: concentration is the vitriol oil 1 ~ 25% and the water 75 ~ 99% of 98%, concentration be 98% vitriol oil per-cent be weight percentage.
The production method of the mica after acidifying takes first acidifying to carry out compounding ingredient again, sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate generation chemical reaction can be avoided, give full play to raw-material respective characteristic in batching, and obtain complementation, guarantee the mica inner quality after acidifying.
According to the needs of quality product, adopt the mica pH value after sodium carbonate adjustment acidifying, method is simple.
After the acidified process of mica, pH value controls 5.5 ~ 7.0, can improve the utilization ratio of mica.
Mica after acidifying has good adsorptivity, thixotropy, thermostability, plasticity-and close-burning feature.
Mica after acidifying is applicable to produce environment-friendly materials, material of construction, whipping agent and fire product.
