[0040] The present invention also provides a kind of preparation method of thermal insulation paint, such as figure 1As shown, it shows a schematic flow chart of the preparation method of the thermal insulation coating provided by the embodiment of the present invention. For the convenience of explanation, only the parts related to the embodiment of the present invention are shown, and the details are as follows: The preparation method includes the following steps :
[0041] S1. Take 8-20 parts of deionized water, mix with 1-12 parts of xonotlite calcium silicate, 1-9 parts of kaolin, and 5-30 parts of rutile titanium dioxide, mix 0.5-1 part of wetting agent, Add 0.05-0.4 part of defoamer and 0.5-1 part of dispersant into it and stir evenly, then make slurry by mechanical dispersion and ultrasonic dispersion;
[0042] S2. First put the acrylic resin emulsion into the lifting dispersing mixer and stir, then add the slurry prepared in step S1 to 30-40 parts of the stirred acryl...
Embodiment 1
[0057] According to formula weight in table 1, prepare according to the following steps:
[0058] (1) Mix deionized water, xonotlite-type calcium silicate, kaolin, and rutile-type titanium dioxide evenly, add half of the wetting agent, half of the defoamer, and dispersant in an appropriate amount, stir evenly, and then mechanically disperse and ultrasonic dispersion to make slurry;
[0059] S2. First put the acrylic resin emulsion into the lifting dispersing mixer and stir, then add the slurry prepared in step S1 into the stirred acrylic resin emulsion, keep stirring, add the other half of the wetting agent, and the remaining dispersion agent, the other half of the defoamer, film-forming agent, anti-fungal agent and leveling agent, mechanically stirred, the low-speed stirring rate is 450r / min, and the stirring time is 60min;
[0060] S3. The slurry after low-speed stirring in step S2 is uniformly dispersed under the effect of a high-speed disperser, and the stirring rate of t...
