Problems solved by technology

[0004] However, there are still many problems to be solved urgently in the research and development of nanocomposite coatings. The most critical issue is how to ensure the effective and stable dispersion of nanoparticles in the coating , if the nanoparticles in the nano-coating are not well dispersed, not only will the intended purpose not be achieved, but the stability of the coating may also be damaged
As far as the currently developed water-based nano-coatings are co

Embodiment 1

[0048] A nano heat-insulating coating of the present invention is formed by mixing pigments, film-forming substances, heat-insulating fillers and additives in a solvent. The mass percentage of each raw material is: pigment: titanium dioxide 32%; film-forming substance: acrylic resin 30%; thermal insulation filler: 6% nano-zirconia, 11% nano-alumina; additives: 1% wetting agent, 1% dispersant, 1% defoamer, 1% silane coupling agent, multifunctional additive 1%; solvent: water 16% for batching.

[0049] The titanium dioxide is obtained by calcining anatase-type titanium dioxide at 900°C for 2 hours, then grinding and controlling its particle size to ≤50 μm;

[0050] The particle size of the nano-zirconia is 10-20 ;

[0051] The one-dimensional diameter of the alumina fiber is 10-20 .

[0052] The preparation method of above-mentioned nano heat insulating coating adopts following steps:

[0053]Weigh the material according to the mass percentage of each component in the for...

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a nano heat-insulating coating and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of society, people pay more and more attention to environmental and energy issues. The development direction and product structure of the world's coatings have undergone significant changes. The development of coatings is in the direction of resource saving, energy saving and pollution-free. With the development, water-based coatings and powder coatings have appeared one after another. Water-based coatings refer to coatings that use water as the dispersion medium. The organic solvents are less volatile, pollution-free, safe and non-toxic. It is the mainstream direction of modern coating development. Compared with solvent-based coatings Compared with water-based coatings, the biggest advantage of water-based coatings is that the amo...
