As can be seen from the curing time in table 1, the absence of the 3,3 '-dihexyl oxocarbocyanine iodide salt in comparative example 2 results in significantly longer curing time than examples 1-4 and comparative example 1 for comparative example 2, and in the waterproof coating, the subsequent curing time can be effectively shortened by modifying the filler with the 3, 3' -dihexyl oxocarbocyanine iodide salt, and the curing time is generally less than 400 s.
On the other hand, comparative example 1, in which zinc laurate was added, has a hardness at high temperature (80 ℃) smaller than those of examples 1 to 4 and comparative example 2, and shows that zinc laurate can improve the thermal stability of the waterproof coating to some extent.
In the process of preparing the environment-friendly single-component polyurethane waterproof coating, during filler modification, the filler is firstly subjected to freeze-drying treatment, after the filler is recovered to room temperature, the filler is sieved, the mesh number of the screen is 600 meshes, powder below the screen is removed, then subsequent grinding treatment is carried out, through freeze-drying operation, the part with lower strength on the filler can be frozen and cracked, and then sieved and removed, the remaining part has high strength, and the quality of subsequent products is improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
