As can be seen from the data in Table 2, in the embodiment of the invention, the hydrocarbon resin and the SBS rubber are used as crosslinking matrix materials, the crosslinking network is formed by dissolving in the dispersion medium, and the waterproof reinforcing effect of the modified fiber material is matched, so that the waterproof plugging agent with high paint film elasticity, strong adhesive force and high viscosity can be formed, and the compressive strength is improved while the waterproof performance is ensured.

The compression strength is measured by pressing the waterproof plugging agent prepared in the example 5 and the samples prepared in the comparative examples 4 to 6 into test pieces of 40mm × 40mm × 160mm, and measuring the compression strength according to GB/T17671. Specific results are shown in table 3.

As can be seen from the data in table 3, in the embodiment of the present invention, the modified slag powder, the calcite powder, the triple superphosphate powder, the titanium dioxide powder, and the calcined kaolin are mixed and ground to form the powder, compared with a method in which one of the triple superphosphate powder, the titanium dioxide powder, the calcined kaolin, and the like is singly used, the compressive strength of the waterproof plugging agent can be effectively improved, and meanwhile, the hydraulic gelation property of the modified slag powder can play a good role in a framework, so as to further improve the compressive strength.

While the preferred embodiments of the present invention have been described in detail, the embodiments of the present invention are not limited to the above embodiments, and various changes can be made without departing from the spirit of the embodiments of the present invention within the knowledge of those skilled in the art. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the embodiments of the present invention are still within the scope of the embodiments of the present invention as thus claimed.
