Embodiment 1
[0037] High temperature resistant coatings are prepared by the following steps:
[0038] Step 1. Add 15.6 mL of siloxane monomer to a four-necked flask equipped with a condenser, thermometer, dropping funnel and stirrer, stir to raise the temperature, add 8.5 mL of deionized water and 0.65 mL of catalyst to the dropping funnel, When the temperature in the four-neck flask rose to 65°C, deionized water and catalyst were added dropwise, and the temperature was continued to rise to 85°C, and the reaction was carried out at a constant temperature for 3 hours, and finally, vacuum distillation was carried out for 2 hours, and the pressure was set at 0.06MPa to obtain a silicone prepolymer;
[0039]Step 2: Weigh 9.5mL of epoxy resin, 13.5mL of acetone and 6.8mL of ethyl acetate into the reaction kettle, heat in a water bath until the epoxy resin is completely melted, then add 5.8mL of silicone prepolymer, stir and heat up to 80 At ℃, add 0.3mL catalyst dropwise to raise the temperatur...
Embodiment 2
[0042] High temperature resistant coatings are prepared by the following steps:
[0043] Step 1. Add 13.6mL siloxane monomer into a four-necked flask equipped with a condenser, thermometer, dropping funnel and stirrer, stir to raise the temperature, add 6.5mL deionized water and 0.55mL catalyst into the dropping funnel, When the temperature in the four-necked flask rose to 65°C, deionized water and catalyst were added dropwise, and the temperature was continued to rise to 85°C, and the reaction was carried out at a constant temperature for 3 hours. Finally, vacuum distillation was carried out for 2 hours, and the pressure was set at 0.07 MPa to obtain a silicone prepolymer;
[0044] Step 2. Weigh 6.5mL of epoxy resin, 10.2mL of acetone and 4.1mL of ethyl acetate into the reaction kettle, heat in a water bath until the epoxy resin is completely melted, then add 3.5mL of silicone prepolymer, stir and heat up to 80 At ℃, add 0.1mL catalyst dropwise to raise the temperature to 95℃...
Embodiment 3
[0047] The high temperature resistant composite color steel tile is prepared by the following steps:
[0048] The first step is to use production equipment to cold-press the composite steel plate to obtain composite color steel tiles;
[0049] In the second step, the high-temperature-resistant paint prepared in Example 1 is evenly coated on the surface of the composite color steel tile, and dried at room temperature to obtain a high-temperature-resistant composite color steel tile.
