Embodiment 1
[0028] Weigh 50g of Lumiflon LF-100 fluorocarbon resin in a 300ml beaker, add 40g of Nanos type nano slurry, then add 2g of china clay, 2g of light calcium carbonate, 1g of talcum powder, then add 2g of toluene, 2g of methyl ethyl ketone, and 1g of ethyl acetate. The mixed paint is dispersed with a high-speed disperser at 1500rpm for 20 minutes, then ground with a sand mill for 5 hours, and finally filtered with a 200-mesh copper mesh to prepare a modified synthetic resin component; the curing agent component is Desmudur N75; The curing agent and the modified synthetic resin component are mixed according to the ratio of NCO:OH=1:1 (molar ratio), and after stirring, use a spreader to remove oil and water in a 50mm×50mm×1mm The LY12 aluminum alloy plate was coated with the nano-photocatalytic fluorocarbon resin coating, and the coated sample was dried at room temperature to make a coating sample with a dry film thickness of 10±2 μm.
Embodiment 2
[0030] Weigh 50g of Lumiflon LF-200 fluorocarbon resin in a 300ml beaker. Add 5g of Nanos type nano slurry, then add 2g of china clay, 2g of light calcium carbonate, 1g of talcum powder, then add 25g of toluene, 10g of methyl ethyl ketone, and 5g of ethyl acetate. Grind with a sand mill for 5 hours, and finally filter with a 200-mesh copper mesh to prepare a modified synthetic resin component; the curing agent component is Tolonate TM HDT-90; the curing agent and the modified synthetic resin component are mixed according to the ratio of NCO: OH = 1: 1 (molar ratio), and after stirring, use a spreader in a 50mm×50mm after degreasing and dewatering treatment. The nano-photocatalytic fluorocarbon resin coating was coated on an LY12 aluminum alloy plate with a diameter of 1 mm. After the coated sample was dried at room temperature, a coating sample with a dry film thickness of 10±2 μm was prepared.
Embodiment 3
[0032] Weigh 35g Ford in a 300ml beaker Fluorocarbon resin. Add 60g of Nanos type nano slurry, then add 2g of china clay, 2g of light calcium carbonate, and 1g of talcum powder, and disperse the above mixed paint with a high-speed disperser at 1500rpm for 20 minutes, then grind it with a sand mill for 5 hours, and finally use a 200-mesh copper mesh Prepare the modified synthetic resin component after filtering; the curing agent component is CORONATE HX-T; the curing agent and the modified synthetic resin component are in the ratio of NCO: OH = 1: 1 (molar ratio), after stirring Use a wire bar coater to coat the nano-photocatalytic fluorocarbon resin coating on the LY12 aluminum alloy plate of 50mm × 50mm × 1mm after degreasing and dewatering treatment. After the sample coated with the coating is dried at room temperature, it is made Coated samples with a dry film thickness of 10 ± 2 μm.
