[0040] On the other hand, the embodiment of the present invention also provides a preparation method of the water-based plastic paint, the preparation method comprising: determining the mass content of each component in the water-based plastic paint;
[0041] Add water-based UV curable resin into the reaction kettle, add wetting agent and leveling agent under stirring state, and stir evenly.
[0042] Add thickener and stir evenly, then increase the speed, add defoamer and nano inorganic filler and stir evenly.
[0043] Reduce the rotational speed, add film-forming aids, deionized water and a photoinitiator, and stir evenly to obtain a water-based plastic paint.
[0044] Through the above preparation process, the above components can be fully mixed evenly to obtain a water-based plastic paint with good uniformity. The above preparation method is simple and easy to operate, which is beneficial to improving production efficiency.
[0045] It can be understood that the mass cont...
Embodiment 1
[0061] Present embodiment provides a kind of water-based plastic paint, and its preparation method is as follows:
[0062] Add 107 parts of LUX399 into a stainless steel tank with a high-speed dispersing device, turn on the high-speed dispersing device, turn the speed to 600 rpm, and add 0.5 parts in turn Wet KL 245 and 0.1 part of BYK-333, after stirring for 2 minutes, add 0.3 part of TAFIGEL PUR85, continue stirring for 10 minutes, then adjust the speed to 1500 rpm, add 0.8 part Airex902W, 2.2 parts of nano-kaolin, keep stirring for 15 minutes, reduce the speed to 800 rpm, add 6 parts of lauryl alcohol ester, 11 parts of deionized water and 3 parts of 1173:BP photoinitiator with a mass ratio of 1:1 , stop stirring after 20 minutes, filter with 200 mesh filter cloth, obtain water-based plastic paint. The following embodiments are similar.
[0063] Utilize the water-based plastic paint prepared by the present embodiment to form a paint film on the plastic substrate, the ...
Embodiment 2
[0069] Present embodiment provides a kind of water-based plastic paint, and its preparation method is as follows:
[0070] Add 117 parts of LUX250 into a stainless steel tank with a high-speed dispersion device, turn on the high-speed dispersion device, rotate at 600 rpm, and add 0.5 parts in turn Wet KL 245 and 0.5 parts of BYK-333, after stirring for 2 minutes, add 0.3 parts of TAFIGEL PUR44, continue stirring for 10 minutes, then adjust the speed to 1500 rpm, add 0.6 parts Airex901W, 2.8 parts of nano-silica, keep stirring for 15 minutes, reduce the speed to 800 rpm, add 5 parts of propylene glycol phenyl ether, 12 parts of deionized water and 6 parts of 184:BP photoinitiated with a mass ratio of 1:1 agent, stop stirring after 20 minutes, and filter with 200 mesh filter cloth.
[0071] The water-based plastic paint prepared in this embodiment is used to form a paint film on a plastic substrate, and the steps are the same as those in Example 1.
