The nanometer heat isolation paint consists of the following ingredients in percentage by mass: 30 to 40 percent of titanium white powder, 6 to 7 percent of nanometer zirconium oxide, 10 to 15 percent of nanometer aluminum oxide, 0.5 to 5 percent of wetting agents, 0.5 to 5 percent of dispersing agents, 0.5 to 5 percent of defoaming agents, 0.5 to 5 percent of silane coupling agents, 0.5 to 5 percent of multifunctional auxiliary agents, 10 to 40 percent of film forming materials and 10 to 40 percent of solvents, wherein acrylic resin is used as the film forming materials, the titanium white powder is used as pigment, water is used as the solvents, the nanometer zirconium oxide and the nanometer aluminum oxide are used as heat isolation filling materials, and the heat isolation paint is obtained after the mixing, uniform stirring and ultrasonic wave oscillation treatment. The heat isolation paint provided by the invention is uniformly coated on the surface of a work surface, the heat isolation and heat insulation effects can be reached, simultaneously, the nanometer heat isolation paint provided by the invention has the effects of radiation protection, falling prevention, waterproof function, fireproof function, crack prevention, freezing prevention, washing and brushing resistance, acid and base resistance and stain resistance, in addition, the cost is low, the construction is convenient, and the use is safe.

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...

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 concerned, most of them have problems such as poor thermal insulation effect, poor storage stability, poor stain resistance and poor coating adhesion. Therefore, how to choose suitable nano-particle thermal insulation fillers and additives to make nano The material is really dispersed in the water-based coating at the nanometer level, and its nano-effect is exerted to obtain a high-performance and stable water-based nano-coating, which has very important application value
