Such as CN200880014618.6, CN201110233081.6, CN201280012287.9, CN201410404059.7, in order to improve the anti-aging performance of titanium dioxide, the surface of titanium tetrachloride is coated with silicon dioxide or phosphate to form a dense glass-like film, However, the coating of these substances hinders the transmission of light, and the corresponding whiteness and gloss of titanium dioxide are significantly reduced.
On the other hand, the process of coating this dense film will lead to a certain degree of agglomeration of titanium tetrachloride particles. Although there is secondary crushing in the subsequent process, it still significantly affects the monodispersity of titanium dioxide.

Embodiment

[0015] A preparation method of titanium tetrachloride pigment for oil paint, comprising the following steps. Step (A): dry grinding, pulverizing the calcined rutile titanium tetrachloride to form crude rutile titanium dioxide. The crushing is carried out by the grinding roller and grinding ring of the Raymond machine, which has little pollution to the product, and the product has good fineness and low oil absorption. At the same time, adjust the feed speed of the Raymond machine, the speed of the classifier, the air intake and other parameters so that the fineness of the crushed particles is 45 μm, and the sieve residue is ≤0.05%. Step (B): sieving, diluting the concentration of the rutile titanium dioxide slurry to 250g / L, and removing larger coarse titanium dioxide particles in the slurry through a sieve. Step (C): Coating, adding inorganic salts into the coating tank, the inorganic salts are mainly zirconium salts and aluminum salts. And the pH value is adjusted by adding...

Abstract

The invention relates to a preparation method of titanium tetrachloride pigment for oil paint, and belongs to the field of chemical engineering. The method comprises the steps of dry grinding, sieving, film coating, air-powder obtaining and the like. Silicon ingredients and boron ingredients are mainly added during the wet grinding. Compared with the prior art, the method has the advantages that the silicon ingredients and the boron ingredients are mainly added in the grinding process, so that the titanium tetrachloride is ground to a certain fineness and concentration; the original stage particle size of the titanium tetrachloride pigment is maintained; the glomeration of titanium tetrachloride particles due to film coating can also be prevented; meanwhile, the transmission performance oflight on the surface of titanium tetrachloride is improved; the luster degree in the use process is improved.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation method of a titanium tetrachloride pigment for oil-based paints. Background technique [0002] As the theme of furniture production and sales, environmental protection is impacting every link of furniture production and raw and auxiliary materials. For furniture coatings, it is also undergoing a transformation from traditional wood coatings to environmentally friendly coatings. The development of water-based wood paint complies with the requirements of environmental protection regulations, greatly reducing the release of organic compounds in wood paint, and is becoming another market hotspot after architectural latex paint for interior and exterior walls. At present, there are three main types of water-based wood paint products in my country: one is wood paint with acrylic acid as the main component. Low and not high-tech. The second is the composition...
