Problems solved by technology

If all kinds of heat insulation coatings are used alone, the heat insulation effect will not be increased.
If the three heat-insulating mechanism coatings are superimposed, although the heat-insulating effect of the composite coating will be improved, it will also have disadvantages such as cumbersome construction and increased costs.

Abstract

The invention relates to the technical field of thermal insulation coatings, in particular to a water-based nano composite heat preservation and insulation coating which is prepared from the following raw materials in parts by weight: 12-18 parts of nano reflective powder, 0.8-1.2 parts of a dispersing agent, 8-12 parts of water, 4-14 parts of infrared powder, 30-40 parts of acrylic emulsion, 12-16 parts of elastic resin and 12-18 parts of hollow glass beads. The hollow glass beads, the nano reflective (one or more than two of titanium dioxide, zinc oxide and calcium carbonate) dispersion liquid and micron-sized tremolite powder are selectively added, and the self-assembly effect generated in the film forming process enables the composite coating to have the functions of barrier property, reflectivity, radiation resistance and the like at the same time, and the reflection, heat insulation and heat preservation performance of the paint film is comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation coatings, in particular to a water-based nano-composite thermal insulation coating and a preparation method thereof. Background technique [0002] With the development of social economy, the consumption of energy is increasing day by day. Energy issues play an important role in the economic development of countries all over the world. Therefore, the topic of energy saving and heat insulation has become an important topic in the social science circle today. In terms of energy consumption, building energy consumption accounts for a large part of the total energy consumption of the society. Therefore, building energy conservation is particularly important in optimizing energy-saving structures and controlling energy consumption. Traditional thermal insulation materials generally choose substances with low thermal conductivity. However, the thermal conductivity of the raw materials actuall...
