Normal-temperature waterborne marking paint

Abstract

The invention relates to the technical field of marking paint, in particular to normal-temperature waterborne marking paint. The normal-temperature waterborne marking paint is prepared from horse oilmodified waterborne polyurethane, epoxy acrylate grafted modified waterborne polyurethane, bisphenol-A epoxy resin, waterborne acrylic emulsion, waterborne polyhydroxy fluorocarbon resin, waterborne lithium silicate, fatty alcohol-polyoxyethylene ether, methyl calcium silicate, nano-titanium dioxide, nano-calcium carbonate, calcined kaolin, calcium chloride, inorganic asbestos fiber, macromoleculefiber, methane disulfonic acid sodium salt, hexamethyldisiloxane, tri(propylene glycol) butyl ether, propylene glycol, butyl cellosolve, waterborne polyamide wax, organic bentonite, an aluminum-zirconium coupling agent, a silane coupling agent, tetrahydro perfluorodecyltrichlorosilane, polyvinylpyrrolidone, vinyl fatty acid ester, a photoinitiator and a photosensitive diluent active monomer. Allthe raw materials are synergistic, so that the marking paint is endowed with good film-forming curing property, permeation adhesiveness with a road surface, water resistance, abrasion resistance, mechanical strength and antifouling and easy cleaning properties.

Description

technical field [0001] The invention relates to the technical field of marking paint, in particular to a normal temperature water-based marking paint. Background technique [0002] Entering the 21st century, the total mileage of my country's highways has exceeded 1.25 million kilometers, and the passenger and freight volumes undertaken by my country's highways have accounted for 88.7% and 99% of the total national traffic volume, which is the foundation and lifeline of national economic development. However, compared with developed countries, my country's traffic facilities are still insufficient, and traffic management is still weak. Take road markings as an example, except for large and medium-sized cities and high-grade highways, most of the general roads have no markings, and 90% of the coatings used on roads with markings are room temperature drying solvent-based coatings, mainly based on C5 The hot-melt type based on petroleum resin and the normal temperature solvent ...

Problems solved by technology

Moreover, most urban roads are drained by gutters. Once the gutters are blocked, the water will not drain out, and the markings will be soaked for a long time, resulting in hollowing, foaming, and peeling off in pieces.
