Problems solved by technology

However, since the glass beads are inorganic substances, they are not compatible with the marking paint made of organic materials, and are prone to fall off during use, resulting in a decrease in the reflective ability of road markings
On the other hand, the surface of the marking paint will absorb a large amount of pollutants during use, reducing the brightness and reflective effect of the marking paint
All these factors have brought danger to the driving safety on the road surface.

Abstract

The invention discloses a high-brightness marking coating. The high-brightness marking coating is prepared from a double-component acrylic resin marking coating matrix and modified glass beads accounting for 60%-75% of the coating matrix, wherein a component A of the double-component acrylic resin marking coating matrix is prepared from 30%-50% of active acrylic resin, 10%-20% of titanium dioxide, 0.1%-0.3% of an anti-settling agent, 1%-15% of an organosilicone component and the balance of filler; a component B of the double-component acrylic resin marking coating matrix is prepared from 30%-50% of active acrylic resin, 10%-20% of titanium dioxide, 0.1%-0.3% of the anti-settling agent, 2%-5% of an initiator and the balance of filler; a ratio of the component A to the component B is (1-3):1. With the adoption of the high-brightness marking coating, lasting light reflecting power of the marking coating can be improved, and traveling safety of a vehicle on the road is improved.

Description

technical field [0001] The invention relates to a method for preparing a high-brightness marking paint, which belongs to the field of transportation, and in particular relates to a method for preparing a paint for improving the long-lasting reflective ability of the marking paint. Background technique [0002] Compared with paints in other fields, the application environment of road marking paint is more severe. It not only has to withstand the test of environmental temperature changes, sun and rain, but also faces rolling and friction from wheels. The current marking paint generally sprinkles glass beads on the mixing surface during use to improve the retroreflective performance of the marking paint, improve the reflective effect, and prolong the service time of road markings. However, since the glass beads are inorganic substances, they are not compatible with the marking paint made of organic materials, and are prone to fall off during use, resulting in a decrease in the ...
