Embodiment 1

[0018] The waterproof type architectural exterior wall coating of the present invention comprises the following components in parts by weight: pure acrylic emulsion, methacrylic acid emulsion, alkyd resin, silica sol, defoamer, titanium dioxide nanopowder, 2-hydroxyl-4-normal Octyloxybenzophenone, cyclohexanone oxime, modified kaolin, titanium dioxide, sepiolite, methyl silicone oil, methylalkoxy silicone oil, octyltriethoxysilane, silane quaternary ammonium salt, surface active agent, antifungal agent. The surfactant is aminated expansive clay. The antifungal agent is a nano antibacterial antifungal agent.

[0019] The invention relates to an exterior wall coating with good waterproof performance. The compounding of methyl silicone oil, methyl alkoxy silicone oil, octyltriethoxysilane and silane quaternary ammonium salt has good waterproof performance. Due to the very low surface tension of silicon material, it is difficult for water to spread on the silicone film; when it ...

Embodiment 2

[0021] Based on Example 1, the described waterproof architectural exterior wall paint includes the following components in parts by weight: 50-60 parts of pure acrylic emulsion, 60-80 parts of methacrylic acid emulsion, 50-80 parts of alkyd resin, 40-50 parts of silica sol, 2-5 parts of defoamer, 5-15 parts of titanium dioxide nanopowder, 5-10 parts of 2-hydroxy-4-n-octyloxybenzophenone, 3-5 parts of cyclohexanone oxime , 5-8 parts of modified kaolin, 8-10 parts of titanium dioxide, 20-25 parts of sepiolite, 10-15 parts of methyl silicone oil, 10-15 parts of methyl alkoxy silicone oil, 5-9 parts of octyltri Ethoxysilane, 8-10 parts of silane quaternary ammonium salt, 5-20 parts of surfactant, 1-3 parts of antifungal agent. The present invention optimizes the most suitable proportioning range in combination with cost.

Embodiment 3

[0023] Based on above-mentioned embodiment, described waterproof building exterior wall paint, comprises the component of following parts by weight: 58 parts of pure acrylic emulsion, 66.5 parts of methacrylic acid emulsion, 75 parts of alkyd resin, 45 parts of silica sol, 4 parts Parts of defoamer, 13 parts of titanium dioxide nanopowder, 8 parts of 2-hydroxy-4-n-octyloxybenzophenone, 4 parts of cyclohexanone oxime, 6 parts of modified kaolin, 9 parts of titanium dioxide, 23 parts of sea foam Stone, 14 parts of methyl silicone oil, 15 parts of methyl alkoxy silicone oil, 8 parts of octyltriethoxysilane, 9 parts of silane quaternary ammonium salt, 12 parts of surfactant, 2 parts of antifungal agent. The present invention optimizes the most suitable ratio value in combination with cost and comprehensive performance. The exterior wall paint of Example 3 was immersed in water at room temperature for 10 days, 12 days, 15 days, 30 days, 60 days, and 90 days respectively. After the ...

Abstract

The invention discloses a waterproof building external wall coating. The waterproof building external wall coatingis prepared from the following components in parts by weight: pure acrylic emulsion, methacrylic acid emulsion, alkyd resin, silica sol, defoamer, titanium dioxide nanometer powder, 2-hydroxyl-4-n-octyloxy-benzophenone, cyclohexanone-oxime, modified kaolin clay, titanium dioxide, sepiolite, methylsilicone oil, methyl alkoxy silicone oil, octyltriethoxysilane, silane quaternary ammonium salt, surfactants, and mildew preventive. According to the waterproof external wall coating, a waterproof agent with good waterproof performance is introduced, so that the external wall coatingishigh in waterproof performance.

Description

technical field [0001] The invention relates to a coating, in particular to a waterproof exterior wall coating for buildings. Background technique [0002] Coating is a kind of material, which can be coated on the surface of the object to be protected or decorated by different construction techniques, and can form a continuous solid film with firm adhesion, certain strength and continuous with the object to be coated. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. Whether it is traditional coating products that use natural substances as raw materials or coating products that use synthetic chemicals as raw materials in modern development, they all belong to organic chemical polymer materials. [0003] Coatings are widely used and are used on exterior walls and floors of buildings. At present, when coatings are applied to the exterior walls of buildings, there are some problems. The waterproof performance of the coatin...
