Abstract

The invention relates to an aqueous pure acrylic reflective heat-insulation coating material and a preparation method thereof, wherein the reflective heat-insulation coating material comprises, by mass, 10-30 wt% of nanometer titanium oxide, 4-20 wt% of infrared heat reflecting powder, 3-7 wt% of a heat-insulating functional material, 30-50 wt% of an aqueous pure acrylic emulsion, 20-30 wt% of deionized water, 0.3-0.5 wt% of hydroxyethyl cellulose, 0.3-0.5 wt% of ethyl cellulose, and the balance of an auxiliary agent. According to the present invention, the particle sizes of titanium dioxide,heat reflective powder and hollow glass micro-beads are different, and the powder obtained by compounding the multi-level particle sizes of the powder meeting the solar wavelength is supplemented, such that the reflective heat-insulation coating material with the good performance is prepared; the viscosity of the slurry can be adjusted with the added ethyl cellulose and the added hydroxyethyl cellulose to form the network structure, such that the pigment filler is connected, the consumption of the resin is reduced, and the energy loss is reduced.

Description

technical field [0001] The invention relates to a coating based on waterborne acrylic resin with reflection and heat insulation, which belongs to the field of reflection and heat insulation coatings. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, human beings' demand for energy is getting higher and higher, and energy consumption is increasing every year. Among them, my country's building energy consumption accounts for about 27% of the country's total energy consumption, ranking first in the country. The first of all kinds of energy consumption. The energy consumption of heating and air conditioning accounts for 55% of the total energy consumption of buildings, and it is still increasing at a rate of 1% per year. Therefore, in order to reduce energy loss, it is of great significance to research and develop architectural reflective heat insulation coatings. The use of coatings with reflective heat...
