Description

A quick-drying paint

technical field

The invention belongs to the technical field of road marking paint, in particular to a quick-drying paint.

Background technique

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-intensive. So it is necessary to develop a quick-drying coating now.

Contents of the invention

In order to overcome the shortcoming of slow drying of the existing hot-melt paint for road markings, the purpose of the present invention is to provide a quick-drying paint.

In order to achieve the above object, the technical scheme that the present invention takes is as follows:

A quick-drying coating, its mass parts array is: 50-65 parts of C5 resin, 180-220 parts of heavy calcium powder, 180-220 parts of quartz sand, 2-4 parts of titanium dioxide, 2-3 parts of PE wax, compound 5~9 parts of plasticizer; wherein, the mass parts of composite plasticizer are ① or ②:

①: DMP 2.5~3.0 parts, polyether polyol 3000 4.0~4.5 parts;

②: DOP 0.9~1.3 parts, DMP 2.2~2.5 parts, polyether polyol 3000 3~4 parts.

Optimally, the mass part array of the paint is: 60 parts of C5 resin, 200 parts of heavy calcium powder, 200 parts of quartz sand, 3 parts of titanium dioxide, 2.5 parts of PE wax, and 7 parts of composite plasticizer; The mass parts array becomes ① or ②:

①: 2.8 parts of DMP, 4.2 parts of polyether polyol 3000;

②: DOP 1.1 parts, DMP 2.4 parts, polyether polyol 3000 3.5 parts.

Preferably, the quartz sand is 200 mesh quartz sand.

Beneficial effects: the present invention designs a composite plasticizer and uses the plasticizer to be compatible with C5 resin according to the ratio shown in the present invention, and the resulting coating can be dried in about 5 minutes, realizing rapid drying.

Detailed ways

The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

Example 1

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 30004.2g.

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.

Example 2

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.

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.

Comparative example

The composition of the coating is the same as in Example 1, except that the composite plasticizer consists of 6.6 parts of DOP and 0.4 parts of polyether polyol 3000.

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 30-45 minutes to achieve complete drying.
