Embodiment Construction

[0011] A kind of preparation method of nanoscale calcium carbonate for anti-corrosion coating, preparation method comprises the following steps:

[0012] (1) Add 120 parts (kg) of light calcium carbonate to an appropriate amount of water, grind it into a nano-slurry, add 1 part of silane coupling agent KH580 at 45°C, stir for 50 minutes, and then add 0.5 part of antioxidant 1076, 1.3 parts of antioxidant BHT, stirred for 15 minutes, filtered, dried, and pulverized;

[0013] (2) Mix 0.1 part of ammonium molybdate, 2 parts of isobutyl methacrylate, 7 parts of rosin resin, and 15 parts of solvent to obtain a modified solution for later use;

[0014] (3) Add the powder obtained in step (1) into a high-speed mixer, keep the temperature at 80°C, add the modification solution, stir for 30 minutes, dry, and grind into nano-powder.

[0015] Adding the coating prepared in this embodiment, the salt spray test result was 22 days, and the salt spray test result was 29 days, which was sign...

Abstract

The invention discloses a method for preparing nano calcium carbonate for anti corrosive paints, wherein the method comprises the following steps of: (1) adding a proper amount of water in light calcium carbonate, grinding the mixture into nano slurry, adding 1-2 parts of silane coupling agent KH580 under 40-50 DEC C, stirring for 30-50 min, then adding 0.3-0.5 parts of anti-oxidant 1076, and 1-2 parts of anti-oxidant BHT, stirring for 10-20min, filtrating, drying and grinding; (2) uniformly mixing 0.1-0.2 parts of ammonium molybdate, 1-2 parts of isobutyl methacrylate, 5-7 parts of rosin resin, and 10-15 parts of solvent, to obtain a modified liquid for standby application; and (3) adding the powder prepared in the step (1) into a high speed mixer, maintaining temperature at 70-80 DEG C, adding the modified liquid, drying after stirring for 20-30min, and grinding to form a nano powder.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a method for preparing nanoscale calcium carbonate for anti-corrosion coatings. Background technique [0002] The existing calcium carbonate applied to the coating has a single function and is cumbersome to use and configure. Contents of the invention [0003] purpose of the present invention. [0004] The above purpose is achieved through the following schemes: [0005] A kind of preparation method of nanoscale calcium carbonate for anti-corrosion coating, it is characterized in that: preparation method comprises the following steps: [0006] (1) Add 100-120 parts of light calcium carbonate to an appropriate amount of water, grind it into a nano-slurry, add 1-2 parts of silane coupling agent KH580 at 40-50 ° C, stir for 30-50 minutes, and then add 0.3- 0.5 parts of antioxidant 1076, 1-2 parts of antioxidant BHT, after stirring for 10-20 minutes, filter, dry and pulverize; [0007] ...
