Abstract

The invention discloses a self-cleaning antibacterial fluorocarbon coating which comprises the following components in parts by weight: 40-60 parts of fluorine-containing polyacrylate resin, 5-13 parts of a silane coupling agent, 1-6 parts of amino resin, 3-15 parts of titanium dioxide, 2-6 parts of calcium carbonate, 10-28 parts of modified nano titanium dioxide, 2-6 parts of silicon nitride, 2-8 parts of zinc molybdate, 5-10 parts of 2,2,4-trimethyl-1,3-pentanediol isobutyrate, 0.3-1.2 parts of 5-chloro-2-methl-4-isothiazolin-3-ketone, 0.2-1.2 parts of defoaming agent, 0.5-1.8 parts of wetting agent, 0.3-0.8 parts of flatting agent, 0.6-1.5 parts of a curing agent and 30-60 parts of a solvent. The self-cleaning antibacterial fluorocarbon coating disclosed by the invention is high in self-cleaning ability and good in antibacterial property and can be applied in building outer walls.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-cleaning antibacterial fluorocarbon coating. Background technique [0002] Fluorocarbon coatings mainly refer to coatings with special functions that use pure fluororesin or modified fluororesin as the main film-forming substance, showing excellent amphobia, weather resistance, durability, acid and alkali resistance, and corrosion resistance. , insulation and non-adhesion, etc., which are beyond the reach of other common coatings, so researchers call it an excellent new type of special coating. Although ordinary fluorocarbon resin has excellent gloss and color retention, fluorocarbon coating itself does not have self-cleaning function, and its stain resistance and antibacterial properties cannot meet the requirements of high antibacterial and strong self-cleaning. Contents of the invention [0003] The invention provides a self-cleaning and antibacterial fluorocarbon c...
