Abstract

The invention provides an improved PC board which comprises a PC board body and anti-UV coatings. The anti-UV coatings are located on the upper surface and the lower surface of the PC board body, theanti-UV coatings are coatings of mixed components of an anti-UV agent and fluorescent powder, and the mixed components comprise the anti-UV agent, the fluorescent powder or the anti-UV agent, the fluorescent powder and a lubricating agent. Ultraviolet detection can be facilitated by adding the fluorescent powder into the anti-UV agent, the manufacturer can quickly detect the coating effect of theanti-UV agent on the surface of the PC board through ultraviolet tools such as a money detection lamp, the inspection process is simple, the cost is low, and the efficiency is high; in addition, afterthe low-cost lubricant is added, the adjacent PC boards are easy to separate after the thin-plate-shaped PC boards, especially the PC waved boards, are stacked. The application of the PC board is skillfully extended to the field of PC boards with less research by utilizing the existing materials, and the outstanding technical effect is obtained.

Description

technical field

[0001] The invention relates to the technical field of air conditioner refrigeration systems, in particular to an improved PC board and a preparation method thereof. Background technique

[0002] PC board is also called polycarbonate board, Capron board. Resistant to weak acids, made of polycarbonate as the main component, using co-extrusion technology CO-EXTRUSION, showing that PC boards are resistant to neutral oils, not resistant to strong acids, not durable, not resistant to alkali, and need to be coated with UV . PC boards also include PC endurance boards, PC sunlight boards, PC particle boards, PC light diffusion boards, PC frosted boards, PC wave boards, etc. Various PC boards are widely used in the field of production and life. For example, PC solid sheet can be widely used in interior decoration, ceiling, ceiling, partition, screen, carport and canopy of buildings; PC light diffusion sheet can be used in advertising light boxes, billboards, LED ele...

Examples

specific Embodiment example 1

[0028] An improved PC board, comprising: a PC board body, an anti-UV coating, the anti-UV coating is located on the upper and lower surfaces of the PC board body, and the anti-UV coating is a coating of a mixed composition of an anti-UV agent and phosphor powder layer.

[0029] Wherein, the fluorescent powder is yellow-green fluorescent powder. After the yellow-green fluorescent powder is added to the anti-UV agent and heated and melted to form a coating of mixed components on the surface of the PC board body, the overall light transmittance of the PC board can be maintained. The anti-UV coating after the phosphor powder is added due to its own Fluorescent properties can emit bright light under the illumination of the light source. The quality inspector only needs to move in the direction of extension of the PC board to judge whether there is light to complete the detection of the integrity of the anti-UV layer. The detection cost is low and the speed is fast. The results are...
