Embodiment 1

[0025] Step 1. Take 200 parts of Ar555 epoxy resin, 50 parts of distilled water, 20 parts of glass beads, and 30 parts of rutile nano-titanium dioxide. After ball milling and dispersing for 30 minutes, add 10 parts of SD998 type defoamer and mix evenly to prepare water-based epoxy road markings. paint mother liquor;

[0026] Step 2, take 4 parts of dopa curing agent and evenly disperse in 30 parts of distilled water, and mechanically stir for 10 minutes to make a uniform and stable mixed solution, that is, to obtain the curing agent mixed solution of water-based epoxy road marking paint;

[0027] Step 3. Mix the mother liquor of the water-based epoxy road marking paint and the curing agent mixed solution at a mass ratio of 8:1, mechanically stir for 10 minutes, and then ultrasonically vibrate for 30 minutes to obtain the water-based epoxy road marking paint.

Embodiment 2

[0029] Step 1. Take 300 parts of H228A water-based epoxy resin, 30 parts of distilled water, 15 parts of glass beads, and 30 parts of nano-rutile titanium dioxide. After ball milling and dispersing for 30 minutes, add 10 parts of GPES type defoamer and mix evenly to prepare water-based epoxy road signs Line paint mother liquor;

[0030] Step 2, take 4 parts of dopa and evenly disperse in 50 parts of distilled water, and mechanically stir for 15 minutes to make a uniform and stable mixed solution, that is, to obtain the curing agent mixed solution of water-based epoxy road marking paint;

[0031] Step 3. Mix the mother liquor of the water-based epoxy road marking paint and the curing agent mixed solution at a mass ratio of 10:1, mechanically stir for 10 minutes, and then ultrasonically vibrate for 30 minutes to obtain the water-based epoxy road marking paint.

Embodiment 3

[0033] Step 1. Take 250 parts of E44 water-based acrylic resin, 80 parts of distilled water, 30 parts of glass beads, and 15 parts of rutile nano-titanium dioxide. After dispersing by ball milling for 30 minutes, add 10 parts of defoamer and mix evenly to prepare the mother liquor of water-based acrylic road marking paint;

[0034] Step 2, take 4 parts of dopa and evenly disperse in 80 parts of distilled water and mechanically stir for 10 minutes to make a uniform and stable mixed solution, that is, to obtain the curing agent mixed solution of water-based acrylic road marking paint;

[0035] Step 3. Mix the mother liquor of the water-based acrylic road marking paint and the curing agent mixture at a mass ratio of 5:1, mechanically stir for 10 minutes, and then ultrasonically vibrate for 30 minutes to obtain the water-based acrylic road marking paint.

Abstract

The invention belongs to the field of road marking paint, and particularly relates to a preparation method of wear-resistant waterborne epoxy road marking paint. According to the preparation method, dopa is used for curing epoxy resin, a highly branched structure formed by combining amino groups on a dopa macromolecule with epoxy groups on macromolecular epoxy resin is a hyperbranched structure, and the hyperbranched structure endows the macromolecular epoxy resin with a three-dimensional structure, so that the toughness and the wear resistance of the waterborne epoxy resin are enhanced; in addition, catechol groups in lateral groups of the dopa are sticky and can be stably adhered to the surface of an asphalt matrix, so that adhesion between the asphalt matrix and the road marking paint is improved; therefore, the wear-resistant waterborne epoxy road marking paint has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of road marking paint, in particular to a preparation method of wear-resistant water-based epoxy road marking paint. Background technique [0002] At present, road traffic marking paints used on highways, high-grade highways and urban roads are mostly three types: normal temperature solvent type, heating solvent type and hot solvent type. In recent years, due to the restrictions on the volatilization of organic solvents by national legislation, water-based paints have become a rookie in road marking paints. Water-based acrylic resin is very popular because of its good wear resistance, weather resistance and acid and alkali resistance. But it still has shortcomings such as poor adhesion, poor water resistance, and poor back-adhesion resistance, which are fatal defects for application in road marking paint. Compared with water-based acrylic resin, water-based epoxy resin not only has the advantages of good adhesion an...
