Example Embodiment
[0021] 1. Example 1:
[0022] A water-based easy-to-heat-dissipate antibacterial insulating coating, including the following components:
[0023]
[0024] The specific preparation method is as follows:
[0025] At a speed of 200-300r / min, add sodium bentonite, propylene glycol, sodium pyrophosphate, paraffin-based mineral oil, and alkyl polyoxyethylene ether to the water, and stir for 5-10min; then the speed will change to 1200-1300r / min, Add mica powder, aluminum nitride, and glass glaze powder, and continue to stir for 15-20min; then the rotation speed is changed to 500-600r / min, and the water-based acrylic resin, 2-methyl-4-isothiazolin-3-one, silicone The leveling agent is added sequentially, and stirring is continued for 10-15 minutes to obtain a water-based, easy-to-heat-dissipate antibacterial insulating coating.
Example Embodiment
[0032] Two: Example 2:
[0033] A water-based easy-to-heat-dissipate antibacterial insulating coating, including the following components:
[0034]
[0035] The specific preparation method is as follows:
[0036] At a speed of 200-300r / min, add calcium bentonite, ethylene glycol, alkyl sulfate, polyether modified dimethylsiloxane, and alkyl aryl polyether to the water, and stir for 5-10 minutes; then Change to 1200-1300r / min, add mica powder, silicon nitride, and glass glaze powder, and continue to stir for 15-20min; then the speed becomes 500-600r / min, and the water-based epoxy resin, 2-n-octyl-4 -Isothiazolin-3-one and modified acrylic leveling agent are added in sequence, and stirring is continued for 10-15 minutes to obtain a water-based, easy-to-radiate antibacterial insulating coating.
Example Embodiment
[0043] Three, embodiment 3:
[0044] A water-based easy-to-heat-dissipate antibacterial insulating coating, including the following components:
[0045]
[0046] The specific preparation method is as follows:
[0047] At a speed of 200-300r / min, add hydrogen bentonite, ethylene glycol butyl ether, maleic anhydride copolymer, polysiloxane, polyether modified dimethylsiloxane to the water, and stir for 5-10min ; Then the rotation speed is changed to 1200-1300r / min, add mica powder, boron nitride, glass glaze powder, and continue to stir for 15-20min; then the rotation speed is changed to 500-600r / min, the waterborne polyurethane resin, phenylpropisothiazoline -3-ketone and polyurethane leveling agent are added in sequence, and stirring is continued for 10-15 minutes to obtain a water-based, heat-dissipating antibacterial insulating coating.
