Embodiment 1

[0015] A kind of quick-drying coating, it is composed of: C5 resin 60g, heavy calcium powder 200g, 200 mesh quartz sand 200g, titanium dioxide 3g, PE wax 2.5g, composite plasticizer 7g; Wherein, the composition of composite plasticizer is : DMP 2.8g, polyether polyol 3000 4.2g.

[0016] During construction, first put C5 resin, heavy calcium powder, 200-mesh quartz sand, titanium dioxide, and PE wax into the container and stir evenly, then put the container on the heating device to heat, and keep stirring during this period to make the temperature reach 200°C, pour it out after it is completely melted, and put it into the heat preservation melting hopper of the marking car. The molten paint is then introduced into the marking hopper and kept warm to keep the material in a molten state. The thickness of the marking coating drawn by the paint is 2mm , and the marked line is cooled at room temperature for 5-8 minutes to achieve complete drying.

Embodiment 2

[0018] The composition of the paint is the same as in Example 1, except that the composition of the composite plasticizer is: 1.1 parts of DOP, 2.4 parts of DMP, and 3.5 parts of polyether polyol 3000.

[0019] The construction method is the same as in Example 1, and the marking line drawn by the paint in this example is cooled at room temperature for 3 to 5 minutes to achieve complete drying.

Abstract

The invention belongs to the technical field of road marking paint, and in particular discloses a rapidly dried coating which comprises the following components in parts by mass: 50-65 parts of C5 resin, 180-220 parts of coarse whiting powder, 180-220 parts of quartz sand, 2-4 parts of titanium dioxide, 2-3 parts of PE (Polyethylene) wax and 5-9 parts of a composite plasticizer, wherein the composite plasticizer comprises the following components (1) or (2) in parts by mass: (1): 2.5-3.0 parts of DMP (Dimethyl Phthalate) and 4.0-4.5 parts of polyether polyol 3000; (2): 0.9-1.3 parts of DOP (Di-Octyle Phthalate), 2.2-2.5 parts of DMP and 3-4 parts of polyether polyol 3000. The rapidly dried coating disclosed by the invention can be dried within about 5 minutes, and rapid drying can be achieved.

Description

technical field [0001] The invention belongs to the technical field of road marking paint, in particular to a quick-drying paint. Background technique [0002] Road marking paint is one of the main uses of petroleum C5 resin, especially hot-melt road marking paint is developing rapidly abroad. With the popularization of automobiles and the development of expressways, hot-melt road marking paint has become the mainstream of road marking paint. Moreover, the current hot-melt paint has the disadvantage of slow drying. Whenever it is necessary to draw a line, it is necessary to block the road. After the painting is completed, it cannot be opened to traffic as soon as possible, because the freshly painted road paint is soft and viscous. . After the car is pressed, it will cause deformation or stick to the wheels and be taken away. Especially in summer, the temperature is too high, resulting in slower drying of pavement paint, which is not only time-consuming but also labor-inte...
