Problems solved by technology

However, when lithopone is used as a coloring raw material for exterior wall paint, in the natural environment, the wall paint is easily pulverized due to the soaking of wind and rain, which limits the scope of use of lithopone.

Abstract

The present invention discloses one kind of lithopone, and the lithopone features its composition comprising zinc sulfide 6.5-36.5 (in weight portions, the same below), hopeite white 2-30, zinc oxide 0.5, silica 2-10, deposited calcium carbonate 15-40 wt%, barite powder 3, kaolin 3, and deposited barium sulfate 2-7. The lithopone of the present invention has high antirust performance, high corrosion retarding performance, high anode deactivating effect, high acid and alkali resistance, high wear resistance, high chemical stability and high adhesion.

Description

technical field [0001] The invention belongs to the field of coloring raw materials, in particular to a coloring raw material suitable for indoor and outdoor wall paints. Background technique [0002] At present, the coloring raw material of domestic wall paint is mainly lithopone (also known as: lithopone), which has the advantages of alkali resistance and heat resistance. However, when lithopone is used as a coloring raw material for exterior wall paint, in the natural environment, the wall paint is easily pulverized due to the soaking of wind and rain, which limits the range of use of lithopone. Contents of the invention [0003] The object of the present invention is to provide a Lido powder, which has good adhesion, strong wear resistance, and good anti-corrosion and anti-rust performance. [0004] For reaching above-mentioned purpose, the present invention provides a kind of Lithol powder, it is characterized in that described Lithol powder is composed of zinc sulfi...
