Abstract

The invention relates to a waterborne FEVE (chlorotrifluoroethylene copolymer) fluorocarbon coating and a preparation method thereof. The coating is prepared from the following raw materials in percentage by mass: 0.05-0.20% of alkaline pH value regulator, 0.05-0.20% of hydroxyl cellulose, 0.10-0.50% of wetting agent, 0.20-1.00% of dispersing agent, 0.05-0.20% of defoaming agent, 1.00-30.00% of pigment, 0.00-30.00% of filler, 0.10-1.00% of nanometer anatase titanium dioxide, 1.00-3.00% of film-forming additive, 0.20-1.00% of thickening agent, 0.00-1.00% of flatting agent, 45-65% of FEVE fluorocarbon resin emulsion and the balance of water. The preparation method comprises the steps of: color paste preparation, paint mixing and the like. The production time is shortened, and air bubbles in the coating are effectively eliminated by combining the effects of machines and auxiliaries. The coating prepared by the invention is a waterborne single-component normal-temperature cured fluorocarbon coating, has excellent weather resistance, pollution resistance, acid rain resistance and mildew resistance, and has the characteristics of environment friendliness, safety, no toxicity and the like.

Description

technical field [0001] The invention relates to a high-performance environment-friendly architectural coating, in particular to a water-based FEVE fluorocarbon coating and a preparation method thereof. Background technique [0002] With the increasingly stringent requirements of the society for energy conservation and environmental protection, coating products show a development trend of high performance, zero volatile organic compounds (VOC), and zero pollution. [0003] Fluorocarbon coating is a coating made of fluorocarbon resin as a film-forming substance. Due to the F-C bond in the fluororesin macromolecular chain (the bond energy is as high as 480kJ / mol, the fluorine atoms tend to be arranged on the surface, which effectively protects the chemical bonds and reduces the surface tension of the resin film). The existence of fluororesin makes the fluororesin coating formulated with fluororesin base material have many excellent properties, such as super weather aging resist...
