Abstract
The invention discloses a preparation method of weather-resistant heavy calcium carbonate, which comprises the steps of adding limestone into a grinder, grinding the limestone into particles with the particle size of less than or equal to 0.25mm to obtain calcium carbonate coarse powder; adding calcium carbonate coarse powder, water, PMA and a first surface modifier into a grinding machine, and grinding by a wet method to obtain calcium carbonate slurry; the first surface modifier consists of polyethylene glycol distearate and polyoxypropylene polyoxyethylene glycerol ether; and conveying the calcium carbonate slurry to a high-speed stirrer, adding a second surface modifier consisting of N-phenyl maleimide, sodium abietic acid diethanol amide ether carboxylate and octaaminophenyl polyhedral oligomeric silsesquioxane, stirring at a high speed, uniformly mixing, dehydrating and drying to obtain the weather-resistant heavy calcium carbonate. The heavy calcium carbonate obtained by surface modification by the method has good dispersibility, hydrophilic and oleophilic properties, thixotropy and processing fluidity, also has good chemical stability, weather resistance and heat resistance, and can be widely applied to industries such as building materials, coatings, rubber, sealants, printing ink and the like.
Description
Technical field
The present invention relates to calcium carbonate modified technical field, the preparation method of specifically a kind of weather-proof powdered whiting.
Background technique
Calcium carbonate is a kind of important inorganic chemical product, is widely used in rubber, plastics, papermaking, coating, oil
In the industry such as ink, medicine, cosmetics, food.But since calcium carbonate particle partial size is smaller, the atomicity on surface is more, then table
Face can be higher, and suction-operated is stronger, mutually reunites between each particle；Followed by calcium carbonate is as a kind of inorganic filler, particle table
Face is hydrophilic and oleophobic, with the compatibility of organic polymer it is poor, easily formed aggregation, cause high polymer internal flaw, mechanical property become
Difference.In order to improve the filling capacity of calcium carbonate, it is necessary to carry out surface to calcium carbonate using effective technique and surface modifying method
It is modified.At present in calcium carbonate modified method, the surface treating agent mainly selected is usually fatty acid or its salt, although system
Dispersibility and processing fluidity make moderate progress, but effect is unobvious.
Since the weatherability of powdered whiting is poor, applies in the industry productions such as building materials, coating, rubber, encounter low temperature
Or calcium carbonate is easy to happen xanthochromia or coacervation occurs etc. under hot conditions.Therefore, research has good dispersion, excellent weather-proof
The good calcium carbonate of property, stability is the demand of today's society.
Summary of the invention
The present invention provides a kind of preparation of weather-proof powdered whiting for defect existing for existing powdered whiting performance
Method.The method of the present invention carries out one-time surface by using polyethylene glycol stearate diester and polyoxyethylene polyoxypropylene glycerin ether
