Embodiment 1
[0031] Step 1. Weigh the following components according to mass percentage,
[0032] Bauxite powder 75%, EPS powder 0.3%, binder polytetrafluoroethylene 12%, binder copper phosphate 12.7%, the total is 100%;
[0033] Step 2, mixing the bauxite powder, EPS powder, polytetrafluoroethylene, and copper phosphate weighed in step 1 in proportion to obtain mixture A;
[0034] Step 3. Put the mixture A obtained in step 2 on a planetary ball mill for high-speed dispersion mixing and stirring for 10 hours to obtain powder fireproof and heat-insulating coating B;
[0035] Step 4. Use a spray gun to spray the powder fire-proof and heat-insulating coating B obtained in step 3 on the surface of the pretreated aluminum alloy, spray twice, and dry at 300°C for 40 minutes to obtain a powder porous fire-proof and heat-insulating coating, and finally Apply fire retardant coating with matching topcoat.
Embodiment 2
[0037] Step 1. Weigh the following components according to mass percentage,
[0038] Bauxite powder 82%, EPS powder 0.5%, binder polytetrafluoroethylene 8%, binder copper phosphate 9.5%, the total is 100%;
[0039] Step 2, mixing the bauxite powder, EPS powder, polytetrafluoroethylene, and copper phosphate weighed in step 1 in proportion to obtain mixture A;
[0040] Step 3. Put the mixture A obtained in step 2 on a planetary ball mill for high-speed dispersion mixing and stirring for 8 hours to obtain powder fireproof and heat-insulating coating B;
[0041] Step 4. Use a spray gun to spray the powder fire-proof and heat-insulating coating B obtained in step 3 on the surface of the pretreated aluminum alloy, spray twice, and dry at 250°C for 70 minutes to obtain a powder porous fire-proof and heat-insulating coating, and finally Apply fire retardant coating with matching topcoat.
Embodiment 3
[0043] Step 1. Weigh the following components according to mass percentage,
[0044] Bauxite powder 88%, EPS powder 0.8%, binder polytetrafluoroethylene 5%, binder copper phosphate 6.2%, the total is 100%;
[0045] Step 2, mixing the bauxite powder, EPS powder, polytetrafluoroethylene, and copper phosphate weighed in step 1 in proportion to obtain mixture A;
[0046] Step 3. Put the mixture A obtained in step 2 on a planetary ball mill for high-speed dispersion mixing and stirring for 5 hours to obtain powder fireproof and heat-insulating coating B;
[0047] Step 4. Use a spray gun to spray the powder fire-proof and heat-insulating coating B obtained in step 3 on the surface of the pretreated aluminum alloy, spray for 3 times, and dry at 200°C for 50 minutes to obtain a powder porous fire-proof and heat-insulating coating. Finally Apply fire retardant coating with matching topcoat.
