preparation example 1

[0042] The preparation method of modified bentonite is: 1) disperse 10kg bentonite in 80kg mass fraction of 10% sulfuric acid solution, stir at 80°C for 4h to obtain bentonite suspension; 2) filter the suspension obtained in step 1), and use Wash the filtered filter cake with distilled water twice. After the washing, dry the filter cake, and then grind the dried filter cake to 100 mesh to obtain bentonite after acidification; 3) 5 kg of ferric nitrate is dissolved in 100 kg of In the water ethanol, ferric nitrate solution is obtained, then 50kg tetrabutyl titanate is added to the ferric nitrate solution, and 2kg parts of nitric acid solution with a mass fraction of 60wt% are added, and the mixed solution is obtained by stirring evenly; 4) the obtained in step 3) Add the mixed solution dropwise to 200kg of water, stir for 30min, and then let stand for 12h; 5) after standing, continue to add 25kg of the acidified bentonite in step 2) to step 4), stir for 2h, and let stand for 20h...

preparation example 2

[0044] The preparation method of modified bentonite is: 1) disperse 10kg bentonite in 90kg mass fraction of 30% sulfuric acid solution, stir at 90°C for 6h to obtain bentonite suspension; 2) filter the suspension obtained in step 1), and use Distilled water washes the filtered filter cake 4 times. After washing, dry the filter cake, and then grind the dried filter cake to 200 orders to obtain bentonite after acidification; 3) 5 kg of ferric nitrate is dissolved in 120 kg of In the water ethanol, ferric nitrate solution was obtained, then 60kg tetrabutyl titanate was added to the ferric nitrate solution, and 5kg mass fraction was added nitric acid solution of 68wt%, and the mixed solution was obtained by stirring; 4) the mixed solution obtained in step 3) Add dropwise to 250kg of water in the solution, after stirring for 60min, let it stand for 18h; 5) after standing, continue to add 35kg of the acidified bentonite in step 2) to step 4), stir for 3h, and let stand for 30h; 6 ) ...

Abstract

The invention relates to the technical field of coatings, and particularly discloses an environment-friendly interior wall coating and a preparation method thereof. The environment-friendly interior wall coating is prepared from the following raw materials in parts by weight: 30-40 parts of inorganic silicate, 10-15 parts of quartz sand, 5-10 parts of modified bentonite, 4-7 parts of coarse whiting, 3-5 parts of titanium dioxide, 2-6 parts of nano boron carbide, 2-4 parts of a thickening agent, 2-4 parts of silicon oxide, 1-4 parts of aluminum oxide, 1-3 parts of magnesium oxide, 0.2-0.8 partof a grinding aid, 0.1-0.5 part of a dispersing agent, 0.3-0.8 part of a defoaming agent, 0.1-0.3 part of a flame retardant, and 25-35 parts of water. The preparation method comprises the following steps: carrying out ball milling on the raw materials, uniformly mixing and stirring with water, adding various assistants, and uniformly mixing to obtain the interior wall coating. The environment-friendly interior wall coating disclosed by the invention does not contain organic matters, and the added modified bentonite can adsorb formaldehyde and further decompose formaldehyde, so that the contentof indoor formaldehyde can be reduced, and the air quality can be improved.

Description

technical field [0001] The application relates to the technical field of coatings, more specifically, it relates to an environment-friendly interior wall coating and a preparation method thereof. Background technique [0002] Paint is a material that is painted on the surface of objects and can be well bonded with the base material and form a protective film. With the development of society and the improvement of human living standards, the demand for using interior wall paint to beautify and improve the living or office environment continues to increase. , while interior wall paint beautifies people's living environment, it also brings a series of indoor air pollution problems. At present, people are paying more and more attention to the living environment, and they have higher requirements for the safety performance of interior wall coatings. [0003] The Chinese patent with the authorized notification number CN104177874B discloses a silica sol interior wall coating, and ...
