Abstract

The invention relates to a road marking coating and a production technology thereof. The technical scheme is characterized by comprising raw materials in parts by mass as follows: 40-50 parts of a fluorocarbon emulsion, 1.4-2.3 parts of rutile type nano-silica, 48-54 parts of filler, 3.5-5 parts of titanium dioxide, 25-28 parts of glass beads, 4-10 parts of a luminescent material and 0.5-1.0 part of auxiliaries, wherein the fluorocarbon emulsion is prepared from tetrafluoroethylene, vinyltri-t-butoxysilane, ethylenesulfonic acid and 4-methyl-3-penten-2-one as comonomers under the action of an emulsifier by adopting an initiating system in a solvent. The road marking coating solves the problem of poor adhesion of a fluorocarbon polymer coating and has excellent chemical stability, heat resistance, durability, contamination resistance, chemical resistance, weathering aging resistance and other functions.

Description

technical field [0001] The invention relates to the technical field of chemical paints, in particular to a road marking paint and a production process thereof. Background technique [0002] Fluorocarbon polymers have excellent chemical stability, heat resistance, electrical insulation, self-lubrication, atmospheric aging resistance and other functions and characteristics, and have been widely used in many fields such as plastics, coatings and elastomers. Especially in terms of coatings, various types of fluorocarbon coatings based on fluorocarbon polymers have become more and more popular, and their application fields have been expanding day by day. This is due to the introduction of carbon-fluorine bonds with large bond energy into the fluorocarbon polymer chain segment, which endows the emulsion with excellent properties, such as durability, stain resistance, chemical resistance, etc., and meets the requirements of both environmental protection and high performance. . Po...
