Embodiment 1
[0035] This embodiment relates to an antistatic thermal control coating composition and its preparation method, and the application of the antistatic thermal control coating composition in the preparation of a new antistatic white thermal control coating.
[0036] The novel antistatic white thermal control coating of the present embodiment is as figure 1 As shown, the coating is upward from the base material 3 and is composed of two layers of paints with different components; the primer layer 2 located in the primer layer is composed of modified organic fluorine resin and zinc oxide with a special spatial configuration; coating The coating on the surface becomes the topcoat layer 1, which is composed of multifunctional methyl silicone resin and modified zinc oxide.
[0037] The novel antistatic white thermal control coating of the present embodiment adopts two-component antistatic thermal control coating composition, and this coating composition comprises primer coating and to...
Embodiment 2
[0045] This embodiment relates to an antistatic thermal control coating composition and its preparation method, and the application of the antistatic thermal control coating composition in the preparation of a new antistatic white thermal control coating.
[0046] This embodiment is basically the same as Embodiment 1, the difference is:
[0047] 1) Primer coating preparation: Add modified zinc oxide powder to the phosphorus-containing modified organic fluorine resin, mix and stir, add butyl acetate, mix, and ultrasonically stir evenly; by mass percentage: modify zinc oxide in the primer The powder accounts for 60wt% of the solid content of the coating, the modified organic fluororesin accounts for 40wt% of the total coating, the mass ratio of the modified organic fluororesin and the modified zinc oxide powder is 60:40, and the butyl acetate diluent is used in an amount of Add 0.1 times of the total weight of the modified zinc oxide powder filler and the modified organic fluori...
Embodiment 3
[0051] This embodiment relates to an antistatic thermal control coating composition and its preparation method, and the application of the antistatic thermal control coating composition in the preparation of a new antistatic white thermal control coating.
[0052] This embodiment is basically the same as Embodiment 1, the difference is:
[0053] 1) Primer coating preparation: Add modified zinc oxide powder to phosphorus-containing modified organic fluorine resin, mix and stir, add xylene, mix, and ultrasonically stir evenly; by mass percentage: modify zinc oxide powder in the primer Accounting for 50wt% of the solid content of the paint, the modified organic fluororesin accounts for 50wt% of the total amount of the paint, the mass ratio of the modified organic fluororesin and the modified zinc oxide powder is 50:50, and the xylene diluent is modified according to its amount. Add 0.15 times of the total weight of zinc oxide powder filler and modified organic fluorine resin.
