Examples
Embodiment 1
[0050] This example provides a water-based non-asphalt-based waterproof coating, and its raw material composition is shown in Table 1, and the preparation method is as follows:
[0051] Dissolve anionic emulsifier, nonionic emulsifier and stabilizer in water to prepare soap solution, and heat to 50°C for later use; mix C5 petroleum resin and aromatic hydrocarbon oil and heat to 120°C, stir evenly to obtain sizing material; sizing material and soap At the same time, a colloid mill is used to prepare an emulsified rubber compound with stable performance; the defoaming agent, bactericidal preservative, anionic SBS latex, anionic SBR latex and the emulsified rubber compound are mixed, stirred evenly, and the thickener is slowly added to reach the set viscosity. 13000mPa . s, to obtain a water-based non-asphalt-based waterproof coating.
Embodiment 2
[0053] This example provides a water-based non-asphalt-based waterproof coating, the preparation process of which is the same as that of Example 1, the difference is only in that the composition of its raw materials is different from that of Example 1, and its specific composition is shown in Table 1.
Embodiment 3
