Description
Technical Field
The invention relates to the technical field of high polymer coatings, and particularly relates to a water-based marking coating.
Background
In the 21 st century, the total mileage of roads in China exceeds 125 kilometers, and the passenger and freight volume borne by the roads in China accounts for 88.7 percent and 99 percent of the total freight volume in China, so that the highway is the basis and the life line of national economic development. However, the amount of traffic facilities in China is still significantly insufficient compared to developed countries, and traffic management is still significantly weak. In terms of road markings, except for large and medium-sized cities and high-grade roads, most of the roads have no markings, and 90% of the coating used on the marked roads is a normal-temperature drying solvent-type coating which mainly adopts a hot-melt type using C5 petroleum resin as a base material and a normal-temperature solvent type using acrylic resin as a base material. However, both solvent-type and hot-melt type marking paints suffer from the disadvantage of releasing volatile substances to contaminate the air to a greater or lesser extent, and also from the disadvantage of being inconvenient to use and handle with hot-melt type marking paints.
The water-based marking paint mainly uses water as a diluent, has obvious advantages compared with a hot-melt type paint and a solvent type paint in terms of environmental protection, but simultaneously uses water as the diluent, and aims to improve the performance of the water-based marking paint in the aspects of curing surface drying rate, wear resistance, water resistance, bonding adhesion with the ground and the like of a coating film. In order to better enhance the adhesion between the conventional water-based marking paint and the road surface, various conditions such as the cleanness degree of the road surface, construction temperature, humidity, wind speed and the like are generally required to be ensured in the construction process, and the construction is generally not suitable under the conditions of high humidity, low temperature and the like. Therefore, innovative research and adjustment on the formula of the water-based marking paint are needed, and it is desirable to prepare a water-based marking paint which can still be normally constructed under the environmental conditions of high humidity, low temperature and the like, so that the construction convenience of the water-based marking paint is improved, and the adhesive force between the coating and the ground is obviously improved. In addition, there is a need to improve the water resistance of aqueous marking paints. The water-soluble property of the film-forming substance adopted in the water-based paint enables the water-based paint to have natural hydrophilic property, and after a coating film formed by the traditional water-based marking paint is soaked in water for a long time, the volume of the coating film is greatly expanded due to the swelling of a base material, so that stress is generated on the interface between a road surface and the coating film, and when the stress reaches a certain degree, the coating film can be peeled from the road surface. In addition, most urban roads are drained by using the ditches, once the ditches are blocked, water cannot be drained, the marked lines can be soaked for a long time, hollowing and bubbling are generated, and the marked lines are peeled off in a large scale. Furthermore, cement pavements have many capillaries which are not visible to the naked eye, and a large amount of water is present in the capillaries, which can erode the markings for a long period of time. Once the water is evaporated, a certain pressure is generated to promote the coating to fall off. Therefore, the performance of improving the water resistance, permeability, bonding force with a road surface and the like of the water-based marking paint has important significance for improving the use value of the water-based marking paint. Meanwhile, no matter what type of marking paint is used for road marking, the marking paint can be continuously rolled by vehicles and the like, so that the marking paint needs to have good wear resistance and mechanical strength, and the marking paint also needs to have antifouling and easy-to-clean performance in order to prolong the service life of the marking. Therefore, innovative improvement is carried out on the formula of the water-based marking paint to improve the film forming and curing performance, the penetration and adhesion performance with the pavement, the water resistance, the wear resistance, the mechanical strength and the antifouling and easy-to-clean performance of the traditional water-based marking paint, and the water-based marking paint has important significance for popularization and application of the water-based marking paint.
