The emulsion paint uses water as diluent, is a material with convenient construction, safety, water washing resistance and good air permeability, and can be prepared into different colors according to different color matching schemes. However, the conventional interior wall coating usually contains formaldehyde, which is easily volatilized, has irritant odor, and easily affects human health when the formaldehyde content in the air is too high, so that the interior wall is easily decorated to emit gas with irritant odor, and easily affects human health and the environment.
Disclosure of Invention

Specifically, the inorganic filler is a mixture of sepiolite, kaolin and talcum powder in a weight ratio of 1:0.2-0.5: 0.1-0.3.
Specifically, the dispersant is polyethylene glycol 200.
Specifically, the silane coupling agent is one of a silane coupling agent KH-550 and a silane coupling agent KH-560.
Specifically, the organosilicon leveling agent is a leveling agent HY-5030.
The invention also provides a preparation method of the environment-friendly energy-saving heat-insulating coating, which comprises the following steps:
step 1: adding ferroceneboronic acid and xonotlite whiskers into a proper amount of solvent, adding a dispersing agent to uniformly disperse the ferroceneboronic acid and the xonotlite whiskers, uniformly dispersing the ferroceneboronic acid and the xonotlite whiskers into cellulose aerogel by an isometric impregnation method, drying at 120 ℃, and removing the solvent to obtain modified cellulose aerogel;
step 2: respectively adding modified cellulose aerogel, acrylate emulsion, water, inorganic filler, silane coupling agent, organic silicon flatting agent, polyethylene glycol and nano titanium dioxide into a container, and shearing and uniformly mixing at room temperature to obtain the environment-friendly energy-saving heat-insulating coating.
According to the environment-friendly energy-saving heat-insulating coating provided by the invention, the cellulose aerogel has a good void structure and a higher specific surface area, so that the cellulose aerogel has a lower heat conduction performance; but because the gap is larger, the gaseous thermal conductivity is still higher, and the aperture can be reduced after the ferroceneboronic acid is added, so that the thermal conductivity of the gas is hindered; the xonotlite crystal whisker with great specific surface area, great surface area volume ratio and chemical activity is introduced into the cellulose aerogel, so that the activation energy of the cellulose aerogel is improved, the heat conductivity coefficient of the cellulose aerogel is further reduced, and the modified aerogel has excellent heat preservation and insulation effects. The cellulose aerogel respectively reduces the heat-conducting property of gas and improves the activation energy by introducing ferroceneboronic acid and xonotlite whiskers; therefore, the modified cellulose aerogel has better heat preservation and insulation effects. The mechanical property and the corrosion resistance of the coating can be improved by adding the inorganic filler and the nano titanium dioxide.
