Abstract

The invention discloses a preparation method of a scrub-resistant calcium carbonate powder interior wall coating. The preparation method comprises the following steps: 1) weighing calcium carbonate, hydrochloric acid, formaldehyde, pure water, sodium pentachlorophenate, styrene, butyl acrylate, methacrylic acid, calcium hydroxide, magnesium hydride, phosphoric acid, sodium hydroxide, paraffin and calcium oxide; 2) putting hydrochloric acid, formaldehyde, pure water, sodium pentachlorophenate, styrene, butyl acrylate, methacrylic acid, phosphoric acid and sodium hydroxide into a reaction still provided with a stirrer and a thermometer, warming to 60 to 80 DEG C, stirring for 30 to 50 min, adding paraffin, cooling to 30 to 50 DEG C, and continuously stirring for 20 to 40 min; 3) warming to 90 to 100 DEG C, adding the remaining raw materials, stirring for 100 to 120 min, grinding through a three-roller grinder, cooling, filtering and examining to be qualified so as to obtain the coating. The coating is bright, clean and smooth and free of power removal or brush mark, the fineness is 25 to 45 microns, the surface dry lasts for 20 to 40 min, and the solid dry lasts for 18 to 22 h; the coating is free of caked paste or precipitate and and is uniform in color and luster, easy for brush application and free of sagging, the heat resistance at 100 DEG C is unchanged for 1 to 5 h, and the adhesive force is 100%.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to a method for preparing a scrubbing-resistant calcium carbonate powder internal wall coating. Background technique [0002] Calcium carbonate is a valuable resource with a wide range of uses. Limestone is the trade name for limestone as a mineral raw material. Limestone has been widely used in the history of human civilization because of its wide distribution and easy access in nature. As an important building material, it has a long history of mining. In modern industry, limestone is the main raw material for the manufacture of cement, lime, and calcium carbide. It is also an indispensable flux limestone in the metallurgical industry. After superfine grinding, high-quality limestone is widely used. Used in the manufacture of paper, rubber, paint, coating, medicine, cosmetics, feed, sealing, bonding, polishing and other products. According to incomplete statistics, the ratio of limestone and ...
