Abstract

The invention relates to a super-hydrophobic self-cleaning seam beautifying agent and a preparation method thereof.The seam beautifying agent comprises two components including a component A and a component B. The component A comprises, by mass, 40-70 parts of fluorine-containing epoxy resin, 5-20 parts of epoxy resin, 1-10 parts of ethyl alcohol, 1-20 parts of modified nano-silicon dioxide, 1-10 parts of nano-titanium dioxide, 0.5-5 parts of a thixotropic agent, 0.1-1 part of a defoaming agent, 0.1-2 parts of an antibacterial agent and 0.1-5 parts of toner; and the component B comprises the following substances in parts by mass: 60-90 parts of a curing agent, 0.5-5 parts of a plasticizer, 1-10 parts of ethanol, 1-20 parts of modified nano silicon dioxide, 1-10 parts of nano titanium dioxide, 0.5-5 parts of a thixotropic agent, 0.1-1 part of a defoaming agent and 0.1-2 parts of an antibacterial agent. The super-hydrophobic self-cleaning sealant disclosed by the invention can show a lotus effect, so that the sealant has super-hydrophobic self-cleaning waterproof and antifouling effects.

Description

【Technical field】 [0001] The invention relates to the technical field of beautifying agents, in particular to a superhydrophobic self-cleaning beautifying agent and a preparation method thereof. 【Background technique】 [0002] With the demand for beautiful home decoration, beauty joints are welcomed by customers in the decoration market. As a high-end joint filling material, it is suitable for filling and beautifying the gaps of ceramic tiles, glass bricks, polished bricks, glazed bricks, antique bricks, whole body bricks, microcrystalline stone, artificial stone, marble, mosaics and other materials. Convenience, various colors, strong wear resistance and so on. [0003] The beautifying agents on the market are easy to turn black and moldy in wet or oily environments. The surface chemical energy of fluorine-containing materials is low, which can play the role of hydrophobic and oleophobic. Chinese patent CN106396479A reports that a one-component beautifying agent containi...
