Abstract

The invention relates to the technical field of hydrophobic coating for an outer wall, and discloses a super-hydrophobic transparent luminous latex coating for an outer wall and a preparation method thereof. The coating is prepared from the following components in percentage by mass: 35-55 percent of styrene-acrylic emulsion, 10-30 percent of luminous pigment, 3-20 percent of stearate, 1-5 percent of nano-silicon dioxide, 3-5 percent of auxiliary and 20-30 percent of water. The super-hydrophobic transparent luminous latex coating for an outer wall has the advantages of low cost, simplicity in preparation and environmental protection, and can be applied in a large scale.

Description

technical field [0001] The invention relates to the technical field of hydrophobic coatings for exterior walls, in particular to a superhydrophobic transparent luminous latex coating for exterior walls and a preparation method thereof. Background technique [0002] According to the internationally recognized classification method, when the contact angle between the solid surface and water is greater than or equal to 90° but less than or equal to 120°, the solid surface is called a hydrophobic surface; when the contact angle between the solid surface and water is greater than or equal to 120° but less than When the solid surface is equal to 150°, the solid surface is called an extremely hydrophobic surface; when the contact angle between the solid surface and water is greater than 150°, and the rolling angle or contact angle hysteresis of water is less than or equal to 10°, the solid surface is called a superhydrophobic surface. [0003] Superhydrophobic surface materials hav...
