Comparative example
The difference from example 1 is that the raw materials and the amounts thereof of comparative examples 1 to 3 are as follows:

Performance test
1. Detecting a sample: the basecoats obtained in examples 1 to 6 and those obtained in comparative examples 1 to 3 were used as test specimens.
2. Detection items and criteria: see table 1 for details.
TABLE 1 test items and standards
3. And (3) analyzing detection results and data:
TABLE 2 Performance test results
As can be seen from the detection data in Table 2, the viscosity of the base coats prepared in examples 1-6 is proper, all the viscosity is in the range of 385 +/-15 MPa.s (25 ℃), the application property is good, the problems of sagging or accumulation and the like are not easy to occur, the coating application thickness is controllable, and the sealing and waterproof effects of the base coats are better. In addition, the base coats prepared in the examples 1 to 6 reach the standard level of the base coats on the detection results of tensile strength, bonding strength and water impermeability, and have wider application range. According to the detection results of the comparative examples 1 to 3, the primer is prepared by particularly adopting three raw materials, namely vinyl methacrylate, adipamide and adipic dihydrazide, and plays a remarkable contribution role in the bonding fastness of the primer, so that the primer has a more durable waterproof effect when being coated on concrete.
In terms of alkali resistance, the examples 1 to 6 can maintain good durability in the alkali-efflorescence concrete, and particularly the alkali resistance of the primer coats of the examples 3 to 6 is more excellent, and for this reason, the inventor guesses that the plasticizer of the examples 3 to 6 particularly adopts a triethyl citrate plasticizer, because the triethyl citrate has certain oxidation resistance, the triethyl citrate reacts with free radicals in a polyurethane polymer system to form excessive hydrogen atoms along with the contact of the primer coat with oxygen in the air, and because a cross-linked network structure formed by the oxalyldiamide, the vinyl methacrylate and the polyurethane has good anchoring adhesion to the concrete, the excessive hydrogen atoms enter the interior through concrete pores to inhibit the hydrolysis reaction of silicate in the concrete, thereby relieving the alkali efflorescence of the concrete, so that the bottom coat is not easy to bulge and separate on the surface of the concrete and has good alkali resistance.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
