[0055] see figure 1 , figure 1It is a schematic diagram of an embodiment of the preparation method of the organic-inorganic composite thermal insulation coating of the present invention. The present invention also provides a method for preparing an organic-inorganic composite heat-insulating coating. The method of this embodiment is the preparation method of the above-mentioned organic-inorganic composite heat-insulating coating. For details about the relevant content, please refer to the above-mentioned organic-inorganic composite heat-insulating coating part and will not be repeated here. The method comprises the steps of:
[0056] S101: Weighing 18%-42% by weight of water glass, adding a predetermined mass of water to dissolve, then adding a predetermined mass of glycolic acid aqueous solution dropwise, stirring and mixing to prepare a mixture A;
[0057] S102: Weigh 8%-25% by weight of hollow glass microspheres and 5%-20% by weight of zinc oxide, add a predetermined mas...
Embodiment 1
[0077] Weigh 20g of water glass, add 30ml of water to dissolve, then add dropwise 4g of glycolic acid aqueous solution with a mass concentration of 25%, stir and mix, and prepare mixture A for later use;
[0078] Weigh 10g of hollow glass microspheres and 5g of zinc oxide in another flask, add 30ml of water, stir at room temperature for 1 hour, and prepare mixture B for later use;
[0079] Weigh 13g of acrylic emulsion into another flask, mix mixture A and mixture B evenly, add to the acrylic emulsion, stir at room temperature for 1 hour, and prepare coating sample 1.
Embodiment 2
[0081] Weigh 35g of water glass, add 40ml of water to dissolve, then dropwise add 7g of glycolic acid aqueous solution with a mass concentration of 25%, stir and mix, and prepare mixture A for subsequent use;
[0082] Weigh 13g of hollow glass microspheres and 14g of zinc oxide in another flask, add 50ml of water, and stir at room temperature for 2.5 hours to prepare mixture B for later use;
[0083] Weigh 8g of acrylic emulsion into another flask, mix mixture A and mixture B evenly, add to the acrylic emulsion, stir at room temperature for 2 hours, and prepare coating sample 2.
