Embodiment 1
[0044] A special waterproof coating for exterior walls, which consists of the following components in parts by weight:
[0045] Modified asphalt: 24.5 parts; anionic slow-cracking emulsifier (sodium lauryl sulfate): 1.5 parts; polymer emulsion (silicone-modified acrylic emulsion): 50 parts; thixotropic agent (organic bentonite): 0.4 parts; Rheological agent (non-ionic associative polyurethane): 0.4 parts; defoamer (organic silicon): 0.2 parts; silane coupling agent (KH560): 0.5 parts; water (deionized water): 22.5 parts.
[0046] The preparation method of this waterproof paint comprises the following steps:
[0047] (1) 23 parts by weight of 90 # The asphalt is heated to about 148°C, and 1.5 parts by weight of SBS (styrene-butadiene-styrene block copolymer) is added to completely swell the asphalt to obtain modified asphalt;
[0048] (2) Evenly disperse 1.5 parts by weight of anionic slow-cracking emulsifier in 22.5 parts of deionized water, raise the temperature to about 57...
Embodiment 2
[0052] A special waterproof coating for exterior walls, which consists of the following components in parts by weight:
[0053]Modified asphalt: 27 parts; anionic slow-cracking emulsifier (sodium lauryl sulfate): 1.5 parts; polymer emulsion (silicone-modified acrylic emulsion): 45 parts; thixotropic agent (organic bentonite): 0.5 parts; Rheological agent (non-ionic associative polyurethane): 0.45 parts; defoamer (organic silicon): 0.15 parts; silane coupling agent (KH560): 0.4 parts; water (deionized water): 25 parts.
[0054] The preparation method of the waterproof coating is the same as that of Example 1, the only difference being that the amount of each component added is the amount of each component mentioned above in Example 2.
Embodiment 3
[0056] A special waterproof coating for exterior walls, which consists of the following components in parts by weight:
[0057] Modified asphalt: 26 parts; anionic slow-cracking emulsifier (sodium lauryl sulfate): 2 parts; polymer emulsion (silicone-modified acrylic emulsion): 50 parts; thixotropic agent (organic bentonite): 0.3 parts; Rheological agent (non-ionic associative polyurethane): 0.3 parts; defoamer (organic silicon): 0.2 parts; silane coupling agent (KH560): 0.2 parts; water (deionized water): 21 parts.
[0058] The preparation method of the waterproof coating is the same as that of Example 1, the only difference being that the amount of each component added is the amount of each component mentioned above in Example 3.
