Abstract
The invention discloses a method for preparing active calcium carbonate, which comprises the following steps of: adding 1 to 10 weight parts of one or a mixture of more of fatty acid and fatty acid salt and 0.05 to 5 weight parts of coupling agent into suspension containing 100 weight parts of calcium carbonate, and modifying at the temperature of between 60 and 90 DEG C for 0.5 to 5 hours to prepare the active calcium carbonate. The method has a simple preparation process and is stable in performance; and the surface of the prepared active calcium carbonate has the good hydrophobicity, is easy to disperse in rubber and resin, improves the combination property of polymers, and can be used in fields of the rubber, adhesives and the like.
Description
Technical field
The present invention relates to a kind of preparation method of nano-calcium carbonate, especially relate to a kind of preparation method who can be used for improving the treated carbonates of rubber, resin over-all properties.
Background technology
Lime carbonate is a kind of important mineral filler, because price is low, raw material is wide, is widely used in the industry such as rubber, plastics, paper, coating, sizing agent, printing ink.Lime carbonate is divided into water-ground limestone, light calcium carbonate according to preparation method's difference.Water-ground limestone is directly to pulverize natural calcite, Wingdale, chalk, white shellfish etc. and make with mechanical means.Light calcium carbonate is to be raw material with the Wingdale, makes unslaked lime through calcining, and unslaked lime adds water digestion and absorbing carbon dioxide carries out carbonization then, and dehydration at last, drying and pulverizing make.Lime carbonate is subjected to the influence of factors such as particle diameter, crystalline form, and its specific surface area of the lime carbonate of equal quality is also different.Particle diameter is more little, and specific surface area is big more, easy more reunion; The surface property of the hydrophilic oleophobic of lime carbonate makes itself and macromolecular material consistency poor, so work in-process easily forms irregular aggregate, cause superpolymer inner disperse inhomogeneous, thereby produce boundary defect, cause the performance of goods to reduce.So people adopt the whole bag of tricks that lime carbonate is carried out surface organic and handle, and are activation treatment again.
At present, domestic research is more various to the surface treatment of lime carbonate.Chinese patent [CN1807519A] adopts unsaturated fatty acids and derivative modified nano-calcium carbonate thereof to make the nano-calcium carbonate that coats one deck unsaturated fatty acids and derivative thereof, is applied to the polymer/inorganic nanometer matrix material.The tensio-active agent of single type easily causes at particle surface and unified intermolecularly makes intermolecular some spaces that occur because of coulombic repulsion repels mutually, causes adsorption layer comparatively loose.Simultaneously, the acidity of single lipid acid own is strong excessively, easily makes calcium carbonate powder agglomerating, dispersed undesirable; Though fatty acid ester can make the lime carbonate surface have good outer lubricity, this class material is often bad with the consistency of other materials, and reactivity own is also not enough.Chinese patent [CN1290935] makes the modified calcium carbonate that a kind of surface has silicon-dioxide, organic acid, silane coupling agent, and is used for polymer composition.But manufacturing process's complexity causes the production cost of enterprise to increase.
Therefore, study treated carbonates a kind of compound surfactant modification, that can be applied to multiple field, both can improve intermolecular consistency of organic polymer and reinforcement such as lime carbonate and rubber, resin, can reduce the production cost of enterprise again.
Summary of the invention
