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.

Abstract

The invention provides a waterproof non-slip coating special for an outer wall and a preparation method and application thereof, and relates to the technical field of building materials, the coating comprises the following components: 21-27 parts of modified asphalt, 1-2 parts of an anionic slow-breaking emulsifier, 40-50 parts of an organosilicon modified polymer emulsion, 0.2-0.5 part of a thixotropic agent, 0.2-0.5 part of a rheological agent, 0.1-0.2 part of a defoaming agent, 0.2-0.5 part of a silane coupling agent and 20-25 parts of water. The prepared coating has high bonding strength, water resistance and anti-sliding performance, is excellent in anti-sagging performance, very high in ductility and high in base layer deformation adaptability, and can be compatible with multiple types of coiled materials.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a special waterproof anti-slip coating for exterior walls and its preparation method and application. Background technique [0002] Coatings used on buildings can be divided into different types, such as interior wall coatings, exterior wall coatings, floor coatings, etc. In addition to the beautifying function, the coating on the exterior wall of the building also needs to have some other functions, such as the protection function of the exterior wall. Since the exterior wall of the building is exposed to wind, sun, and rain all year round, there will be problems such as easy peeling, discoloration, and aging of the exterior wall paint. Therefore, higher and higher requirements are placed on the performance and quality of exterior wall coatings. [0003] Under normal circumstances, exterior wall waterproof coatings not only have waterproof function, but also nee...
