Problems solved by technology

[0003] However, in practical applications, rutile titanium dioxide also has certain limitations, which are caused by the physical properties of rutile titanium dioxide.
(1) There is only a single color - white; (2) The surface of the object is irregular in shape, showing an irregular polygonal shape; (3) The bulk density is greater than 1; (4) The thermal conductivity is large, and there is no barrier thermal conductivity
[0004] Chinese patent: The method of producing inorganic pigments at high temperature in 200710048618.5 is feasible, but has the disadvantages of high calcination temperature, power consumption, long production cycle and low efficiency

Abstract

The invention relates to a preparation method of color ceramic cenosphere pigment and fillers. The preparation method is characterized in that forty to sixty portions by weight of cenosphere and sixty to forty portions by weight of high temperature metal oxide are added into a blender for even blending, are moved into a high temperature resistant vessel, are placed in a high temperature resistance oven for calcination for thirty to fifty minutes under the calcining temperature between five hundred and fifty DEG C to six hundred and fifty DEG C, are put in a sieving machine for sieving after being brought out of the over and natural cooling to obtain the color ceramic cenosphere pigment and fillers with the average particle size between 6.7 and 32.4mu m, the granular percentage more than ninety five percent, the bulk density 227 kg / m<3>, the cylindrical compress strength 566kpa, the coefficient of thermal conductivity 0.050w / (m.k).

Description

technical field [0001] The invention relates to a method for preparing colored ceramic hollow microbead pigments and fillers, which belongs to the field of pigments and fillers preparation. Background technique [0002] In the paint formulation system, in addition to the base material (or binder), additives (dispersant, defoamer, film-forming aid, etc.), pigments and fillers also need to be added. Pigments provide various colors of organic pigments and inorganic pigments for coatings, and fillers provide various inorganic fillers for coatings. Rutile titanium dioxide is both a pigment and a filler. It is a very good and widely used white pigment and filler. [0003] However, in practical applications, rutile titanium dioxide also has certain limitations, which are caused by the physical characteristics of rutile titanium dioxide itself. (1) There is only a single color - white; (2) The surface shape of the object is irregular, showing an irregular polygonal shape; (3) The ...
