Description
Technical field
The present invention relates to a kind of Inorganic Chemicals, specifically calcium carbonate and preparation method thereof.
Technical background
Calcium carbonate is one of Common materials on the earth, is present in aragonite, calcite, chalk, limestone, marble, lime
It is also the main component of animal skeleton or shell in the rocks such as China.Calcium carbonate is not only important construction material, industrial use
(such as plastic industry) is also very wide.
However, conventional form when calcium carbonate production, application is powdered；Powdered calcium carbonate easily causes fugitive dust,
And it is difficult to control；This overall situation further stringent with environmental requirement, it is clear that be inconsistent；And industry is difficult to solve always
Problem.
Summary of the invention
The purpose of the present invention is overcoming the shortcomings of in above-mentioned background, a kind of dustless calcium carbonate and preparation method thereof is provided,
This method should be able to effectively avoid the fugitive dust of calcium carbonate in the production and use process, and production method is simple, and equipment is mature, energy
It consumes low.
Present invention provide the technical scheme that
A kind of dustless calcium carbonate, including raw material and its weight ratio be:
Calcium carbonate 70-90%, auxiliary material 10-30%, the auxiliary material are the mixing of vegetable oil acid and other raw materials, other raw materials
Weight ratio in auxiliary material is 0-10%；
Other described raw materials are epoxidized soybean oil, in fatty acid methyl ester, dioctyl ester, multi-functional environment-protection plasticizer P QT-P-1
One or two or more kinds of arbitrary proportions mixing.
The fineness of the calcium carbonate is -2000 mesh of 300 mesh.
Further, the fineness of the calcium carbonate is -1500 mesh of 300 mesh.
The vegetable oil acid includes palmitoleic acid, soybean oleic acid, cocinic acid, vegetable seed oleic acid, oleic acid, corn oleic acid
One of or two kinds of any of the above ratios mixing.
A kind of preparation method of dustless calcium carbonate carries out as follows:
1) calcium carbonate and auxiliary material are weighed by formula ratio；
2) it is mixed at room temperature；Pack, into library；
Alternatively, being mixed at room temperature, particle is then fabricated to by granulator, then is packed, into library.
The grain diameter is 2-4mm.
The beneficial effects of the present invention are: dust raising phenomenon is completely eliminated since calcium carbonate and auxiliary material adherency agglomerate, from
And meet environmental requirement, it brings great convenience to the products application in downstream.Particularly with plastic industry, additionally it is possible to being produced
Product generate plasticising, demoulding, saponification, antirust, lubrication, cooling and neutralization, when production, is heated to extrusion temperature
When, and can disperse quickly, is compatible；Thus there is breakthrough innovation, be remarkably improved product quality.Production provided by the invention
Method is simple, and use is mature equipment, and energy consumption and cost are relatively low.The dustless calcium carbonate storage timeliness is longer；Storage two
The still favorable dispersibility to 5 years, can normal use.
Specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
A kind of preparation method of dustless calcium carbonate carries out as follows:
1) calcium carbonate and auxiliary material are weighed by formula ratio；
2) it is mixed at room temperature；Pack, into library；
Alternatively, being mixed at room temperature, particle is then fabricated to by granulator, then is packed, into library.
Mixing of the present invention can be determined according to following different working environment:
(1) directly calcium carbonate and auxiliary material can be mixed in a device by common calcium carbonate user.
It (2), can be raw in mining area for calcium carbonate manufacturing enterprise (generalling use totally enclosed pipeline powder lime carbonate)
Produce calcium carbonate milling equipment beside install high-pressure oil pump, and complete milling, by pipeline by powder conveying to store fill
When packaging container, the misty auxiliary material based on vegetable oil acid is sprayed into；It is combined by spraying with wind powder feeding body by this high-pressure oil pump
Mode can efficiently convey the dustless calcium carbonate product flown upward so that quickly agglomerating fugitive dust in totally enclosed pipeline.To solve
Pipeline calcium carbonate at present, because pipe sealing it is not tight caused by dust from flying, lead to the problem of environment is by white pollution.
