Description
Technical Field
The invention relates to the field of coatings, in particular to a road marking coating and a preparation method thereof.
Background
The road marking paint is a paint which is coated on the surface of a road and is used for marking the route and the direction of the road, is a safety mark and is one of important components of traffic facilities. The road marking paint mainly comprises three types of normal-temperature solvent type paint, water-based road marking paint and hot-melt type paint.
Usually, the road sign needs to be clear and accurate, so that the user can use the road sign safely. Along with the development of cities, road planning in the cities can be changed to a certain extent, so that the original road marking paint needs to be changed. The existing modification method of the road marking paint is usually mechanical removal, but the removal method is not thorough, so that the original road mark is still clearly visible on the road surface. With the application of new road marking paint, two different road markings may be present on the same area of the road surface, which may be annoying. Particularly, for a driver, in the driving process, the speed is relatively high, the driver needs to make quick and accurate judgment and reaction on the road mark, when the driver faces two different road marks in the same area, the driver is often difficult to make quick and accurate judgment and reaction, potential hidden dangers are generated on road safety, and even serious traffic accidents are caused.
Therefore, there is a need to develop a road marking paint which is easy to remove and modify, and at the same time, before modification, the road marking paint should maintain the original clear and stable marking effect.
Disclosure of Invention
Aiming at the defects in the technology, the invention provides the road marking paint which is easy to remove and change, and the preparation method of the paint comprises the following steps:
(1) carrying out scribing pretreatment on the surface area of the road needing scribing, forming a reticular groove on the surface of the road according to a preset shape, and then cleaning the surface of the road;
(2) laying a wire mesh with a preset shape in the mesh groove, wherein the diameter of the wire is 5-20% of the width of the mesh groove;
(3) the method includes applying a first layer of a clear coating composition to the surface of the roadway, then applying a second layer of a water-based pigmented coating composition wet-on-wet, and simultaneously curing the first layer of the clear coating composition and the second layer of the water-based pigmented coating composition.
The first transparent coating composition layer has an adhesion effect, so that the adhesion stability of the second water-based coloring coating composition layer and the road surface can be improved, and meanwhile, when the road marking coating needs to be changed, the first transparent coating composition is mechanically removed, so that only less transparent coating is left on the road surface, and the clearness and the accuracy of the changed road marking coating cannot be influenced. Particularly, the wire mesh is laid in the mesh groove in advance, and the medium coating is easily crosslinked on the wire mesh in the curing process. In the coating removal process, the wire mesh is beneficial to adhering and completely stripping the coating on the road surface, so that the transparent coating layer is only slightly or even completely not remained on the road surface.
Wherein the first clear coating composition comprises a water-based polyolefin resin A and a curing agent B.
Wherein the second water-based coloring coating composition comprises a water-based polyolefin resin A, a curing agent B, a pigment C, a leveling agent D, a thickening agent E and a dispersing agent F.
Wherein the water-based polyolefin resin A is selected from one or more of polyethylene resin, polypropylene resin, polybutylene resin, ethylene-propylene copolymer, propylene-butylene copolymer and ethylene-propylene-butylene copolymer.
Wherein the water-based polyolefin resin A has an average molecular weight of 50000-250000.
Wherein, the curing agent B is amino resin, and is specifically selected from melamine resin, urea resin or guanamine resin.
Wherein the mass ratio of the curing agent B to the water-based polyolefin resin A is 2-10%.
Wherein, the pigment C is selected from white pigment or yellow pigment. The white pigment is titanium dioxide, and the yellow pigment is chrome yellow or yellow iron oxide.
Another aspect of the present invention includes the removal and modification of the above-described road-marking paint, which can be directly removed by a mechanical removal method due to the pre-laid wire mesh. The adhesion effect of the wire mesh to the coating is favorable for completely stripping the coating on the road surface, so that the transparent coating layer is only in trace amount or even completely not remained on the road surface, and the accurate, clear, safe and effective identification after the road surface is changed is ensured.
According to the invention, the marking pretreatment is carried out on the road surface in advance, and the reticular grooves are formed on the road surface according to the preset shape, so that the adhesion between the road marking paint and the road surface is increased, and the stability and the strength of the road marking paint are ensured. In addition, the first clear coating composition layer and the second water-based colored coating composition layer both use a water-based polyolefin resin as a main agent, ensuring adhesion stability between the two layers, and similarly using a curing agent. This ensures that the coating can be applied in a wet-on-wet process and then co-cured, saving time.
