Abstract

The invention discloses a wear-resisting waterproof self-cleaning super-hydrophobic lotus leaf effect emulsion paint and a preparation method thereof. The wear-resisting waterproof self-cleaning super-hydrophobic lotus leaf effect emulsion paint is prepared from the following raw materials: polymer emulsion, a coalescing agent, a defoaming agent, an antifreezing agent, a wetting dispersant, a pH modifier, a preservative, a leveling agent, a thickening agent, pigment, filler, polymer micro powder and tap water. The wear-resisting waterproof self-cleaning super-hydrophobic lotus leaf effect emulsion paint disclosed by the invention has the advantages of better anti-fouling performance which can reach 1 grade or above, contact angle of 135 degrees or above, high hydrophobicity, good scrub resistance, good aging resistance and capability of maintaining the external wall as new for a long time; rainwater can instantly slip in a water drop form without internal seepage, the hydrophobic waterproofing function is stronger and the hydrophobic effect is durable; with a surface microstructure of the emulsion paint, dust cannot be effectively contacted with the wall surface, so that the aims of easiness in shedding and self-cleaning are achieved.

Description

technical field [0001] The invention relates to the technical field of latex paint, in particular to a wear-resistant, waterproof, self-cleaning superhydrophobic lotus-leaf effect latex paint and a preparation method thereof. Background technique [0002] At present, the paint market is still dominated by middle and low-end products, mainly for the purpose of decoration, and the market share of functional paints is very small. However, with the continuous deepening of scientific and technological work, people have higher and higher requirements for paints, and new functional paints are constantly emerging. New products have been successfully developed and successfully introduced to the market. Self-cleaning latex paint for exterior walls has entered the market as a functional paint, but the current latex paint is prone to dust on the surface after long-term use, the self-cleaning effect is not long-lasting, the self-cleaning effect is poor, it is not waterproof, seepage, poo...
