preparation example 1

[0045] A Bi 2 o 3 / activated carbon, prepared according to the following steps: 1.5kg of 2.5% nitric acid solution and 1.5kg of absolute ethanol were added in the stirrer, after stirring for 30min at 300r / min, 1.5kg of Bi(NO 3 )·5H 2 O is added to the stirrer, stirred at 400r / min for 50min to obtain a transparent sol, put the transparent sol into the polytetrafluoroethylene liner of the hydrothermal reaction kettle, and put the polytetrafluoroethylene liner into the hydrothermal reaction kettle , then move the hydrothermal reactor into the oven, react at 120°C for 24 hours, take out the reactor, centrifuge the liquid in the polytetrafluoroethylene liner to obtain a solid product, put the solid product into the oven, and heat it at 80 After drying at ℃ for 6h, and then grinding the solid product, Bi 2 o 3 / activated carbon.

preparation example 2

[0047] A Bi 2 o 3 -TiO 2 / activated carbon, prepared according to the following steps:

[0048] (1) Add 1.5kg of tetrabutyl titanate and 4kg of absolute ethanol into the stirrer, and stir for 15min at 200r / min to obtain a titanium-containing solution;

[0049] (2) At 300r / min, add 1.5kg of nano activated carbon into the titanium-containing solution and stir for 15min to obtain a mixed solution;

[0050] (3) the 2.5% nitric acid solution of 1.5kg and the dehydrated alcohol of 1.5kg are mixed uniformly, obtain nitric acid alcohol solution;

[0051] (4) Under the stirring condition of 400r / min, the nitric acid alcohol solution and 1.5kg of Bi(NO 3 )·5H 2 O was added in the mixed solution, and after stirring for 60min, the sol was obtained;

[0052] (5) Add the sol to the polytetrafluoroethylene liner of the hydrothermal reaction kettle, put the polytetrafluoroethylene liner into the hydrothermal reaction kettle, and then move the hydrothermal reaction kettle into the oven....

Abstract

The application relates to the field of building material coating technology, and specifically discloses an anion-friendly environmental protection coating and a preparation method thereof. Negative ion environmental protection paint is made of raw materials including the following parts by weight: 40-70 parts of water-based epoxy resin, 5-15 parts of mixed crosslinking agent, 5-20 parts of negative ion powder, 5-10 parts of bismuth-based activated carbon photocatalyst, dispersant 1-4 parts, 50-100 parts of water; the preparation method is: first mix the anion powder, bismuth-based activated carbon photocatalyst and water uniformly to obtain a suspension; then add the mixed cross-linking agent to the suspension, At 75°C, react for 5-8 hours, and filter to obtain a bismuth-based-anion-activated carbon composite material; then add bismuth-based-anion-activated carbon composite material and dispersant to the water-based epoxy resin, and mix well to obtain an anion-friendly environmental coating . The negative ion environmental protection paint of the present application not only has the effect of releasing negative oxygen ions and preventing corrosion, but also can continuously absorb and decompose free formaldehyde in the air, thereby improving the air purification effect of the paint.

Description

technical field [0001] The application relates to the field of building material coating technology, more specifically, it relates to a negative ion environmental protection coating and a preparation method thereof. Background technique [0002] Negative ion paint contains negative ion powder. Negative ion powder is generally a composite mineral powder synthesized by tourmaline powder and lanthanide elements in proportion. Negative ion powder can ionize the air and generate negative oxygen ions, which help to improve the sleep quality of residents. Ions also have the effect of purifying formaldehyde. Therefore, negative ion paint is an environmentally friendly paint that can improve the living environment. Negative ion coatings can be applied to both walls and furniture. [0003] In the related art, the patent with the notification number CN105602401B discloses a water-based environment-friendly negative ion anti-corrosion coating and a preparation method thereof. The coat...
