Problems solved by technology

[0002] Many coatings used in the current market are to improve the performance and strength of the material itself, and are committed to improving the wear resistance and other process properties of the material, but there are many coatings on the market today that lack practicality, especially at night. Sometimes, under some general lighting conditions, it often happens that the standards are not clear, or the warning signs are not obvious, and pedestrians will have accidents in the process of walking.
[0003] However, the existing reflective materials do not have reflective materials for this purpose. They are some relatively obvious linear reflective materials, which are generally used for road markings. The reflective effect of this reflective material is not obvious, and the reflective effect is not good. Well, when the lighting conditions are poor, the signs cannot be seen normally, and the warning to pedestrians on the side of the road cannot be solved

Embodiment Construction

[0016] Add film-forming resin, ultrafine powder graphite, curing agent, pigments, fillers and additives into the container, and fully mix. After the mixing is completed, melt and extrude under high pressure, and add reflective powder to the extruded fusion. The fusion of reflective powder is processed into tablets, and the compressed tablets are uniform in size, and then the tablets are roughly pulverized using a pulverizer. After the pulverization, the powder is finely pulverized, and the pulverization is completed and packaged for storage.

[0017] Film-forming resins include epoxies and polyurethanes.

[0018] The particles of the reflective powder are made by crushing yellow glass material, and the crushed particles keep the polyhedron shape.

[0019] After the fine crushing, the stirring work is carried out, and the packing is carried out after the stirring is completed.

[0020] The working process of this example: In the process of using, first spray the powder coati...

Abstract

The invention provides a production technology of a reflective powder coating. The production technology comprises the following steps: adding a film-forming resin, superfine powder graphite, a curingagent, a pigment, a filler and an assistant into a container, fully mixing the added raw materials, carrying out melt high-pressure extrusion after the mixing is finished, adding reflective powder into the extruded fusion, tabletting the fusion containing the reflective powder until the pressed tablets are uniform in size, coarsely crushing the tablets by using a crusher, finely crushing the powder after the crushing is finished, and performing packaging and warehousing after the crushing is finished. The reflective effect of the reflective powder coating is improved, and the production process requirements are reduced.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a production process of reflective powder coatings. Background technique [0002] Many coatings used in the current market are to improve the performance and strength of the material itself, and are committed to improving the wear resistance and other process properties of the material, but there are many coatings on the market today that lack practicality, especially at night. Sometimes, under some general lighting conditions, it often happens that the standards are not clear, or the warning signs are not obvious, and pedestrians will have accidents while walking. [0003] However, the existing reflective materials do not have reflective materials for this purpose. They are some relatively obvious linear reflective materials, which are generally used for road markings. The reflective effect of this reflective material is not obvious, and the reflective effect is not good. Well, when the...
