Abstract

The invention discloses a water-based fluorine-containing coating. The coating is prepared from the following main raw materials in percentage by weight: a fluorine-containing acrylate monomer, a non-fluorine-containing monomer, hexafluoroacetone, cyclochloroethane, a PH (Potential of Hydrogen) regulator, an initiator, a flatting agent and a dispersing agent. Required additives comprise the PH regulator, the flatting agent, the initiator and the dispersing agent. The water-based fluorine-containing coating has the advantages of stable product quality and convenience in preparation, has excellent weather resistance, stain resistance, corrosion resistance and the like of a fluorine-containing material, takes the water-based fluorine emulsion as a film-forming substance and water as a solvent, and has the characteristics of non-toxicity, no odor, low VOC emission, safety, non-inflammability and the like of water-based coatings.

Description

technical field [0001] The invention relates to the technical field of water-based fluorine-containing coatings, in particular to a water-based fluorine-containing coating and a preparation method thereof. Background technique [0002] Fluorine-containing coatings refer to coatings with fluorine resin as the main film-forming substance, also known as fluorocarbon coatings, fluorocarbon paints, and fluororesin coatings. Various properties, such as weather resistance, heat resistance, low temperature resistance, chemical resistance, and unique non-stick and low friction, but contain a large amount of organic volatiles, which are extremely serious for environmental pollution and waste resources and waste of energy. [0003] Since general coatings, epoxy resins, and polyurethane furniture paints contain benzene-based volatiles, they have been gradually eliminated by the market. my country's coatings industry is developing in three directions: environmental protection, economy, ...
