Abstract

The invention relates to the technical field of thermal insulation coatings, in particular to a nano transparent thermal insulation coating with a switch function, which comprises the following components in percentage by weight: 10-30% of nano-sized antimony doped stannic oxide dispersion the concentration of which is 30%, 2-10% of nano-sized vanadium oxide dispersion the concentration of which is 30%, 30-70% of film-forming agent, 0.3-0.8% of antifoaming agents, 0.05-0.8% of flatting agent and the balance water. The nano transparent thermal insulation coating is prepared by adding the components to a high-energy stirring mill to stir in accordance with the formula. The coating in the invention has the advantages of safety, non-toxic side effects, non-pollution on the environment, high bonding strength, short drying time, high transparence, non-influence on visual effect, corrosion prevention, acid-base resistance and the like, and is convenient to use.

Description

Technical field: [0001] The invention relates to the technical field of thermal insulation coatings, in particular to a nano transparent thermal insulation coating. Background technique: [0002] Making glass both transparent and heat-insulating has always been a major issue that has plagued technical experts. The emergence of nanomaterials provides a new way to solve the problem of transparent heat insulation. Nanoparticles are atomic groups or molecular groups that are composed of a limited number of atoms or molecules, maintain the chemical properties of the original substance and are in a metastable state. When the linearity of the substance decreases, the relative proportion of the number of atoms on the surface increases, so that the surface energy of the single atom increases rapidly. When it reaches the nanometer scale, the change of this form is fed back to the structure and performance of the material, and it will show strange effects. [0003] The research on o...
