Abstract

A cured nanometer resin fluorinated carbon building coating at normal temperature and its production are disclosed. The process is carried out by using tin catalyst, and adding into wetting disperser, anti-bubbling agent, curing agent, anti-settling agent, ultraviolet absorber and coloring pigment. It achieves long anti-aging time, better water-proof and anti-fouling ability, and higher hardness of coating.

Description

technical field [0001] The invention relates to the field of macromolecule coatings, in particular to fluorine-containing carbon resin nanometer architectural coatings cured at room temperature and a preparation method thereof. Background technique [0002] The diameter of the fluorine atom is the smallest, the F-C bond length is very short, and the bond energy is as high as 477 kJ / mole, so the fluorine resin has excellent high temperature resistance, chemical and organic solvent resistance, friction resistance, oil repellency, water repellency and surface Non-stick, anti-fouling, weather resistance, etc. But its main disadvantage is that it is difficult to process, insoluble in most organic solvents, and its fluidity is still not good when the temperature is as high as 300-400 ° C, which greatly limits the use of fluorocarbon resins. [0003] In 1938, the United States developed PTFE polytetrafluoroethylene resin, which is known as the king of plasti...
