Description

Technical Field

[0001] This utility model relates to a desktop board, specifically a flame-retardant desktop board, and belongs to the field of school supplies. Background Technology

[0002] Students spend most of their study time at their desks. Traditional desks are made of wood or steel. With the call for environmental protection and the limitations of wood processing technology, wooden desks have been gradually phased out. Steel desks have a complex manufacturing process, poor corrosion resistance, and are not aesthetically pleasing. In addition, the two types of desks mentioned above are bulky and have low uniformity.

[0003] To address this issue, existing desktop boards are primarily made of wood-based panels, such as MDF, fiberboard, and particleboard, or plastic panels, such as injection-molded boards. However, wood-based panels lack strength, and some materials contain harmful substances like formaldehyde that endanger students' health. Plastic panels, on the other hand, lack durability, are easily scratched during use, and are difficult to clean. After a period of use, they become brittle and easily damaged, making it difficult to meet the needs of long-term use.

[0004] Furthermore, the desktop panels in the existing technology are made of flammable materials, which can cause the fire to spread rapidly in the event of a fire, and produce a large amount of smoke and harmful gases after burning, posing a safety hazard and threatening the life and health of students. Summary of the Invention

[0005] In view of this, the present invention provides a flame-retardant desktop board to solve the above-mentioned problems existing in the prior art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A flame-retardant desk panel includes an injection-molded board layer, an adhesive layer, and a fire-resistant layer arranged sequentially from bottom to top. The upper end face of the injection-molded board layer is recessed inward to form an installation groove. The adhesive layer is coated in the installation groove. The fire-resistant layer is fixed in the installation groove by the adhesive layer. The upper edge of the fire-resistant layer is flush with the upper end face of the injection-molded board layer. The lower end face of the injection-molded board layer protrudes to form an installation post. The inner wall of the installation post has threads.

[0008] Based on the above technical solution, the present invention can be further improved as follows:

[0009] Furthermore, the rear side and / or the side edges of the injection-molded sheet extend downward to form a protective structure.

[0010] Furthermore, the lower end face of the injection-molded sheet has reinforcing ribs.

[0011] Furthermore, the depth of the mounting groove is 1mm, the thickness of the adhesive layer is 0.2mm, and the thickness of the fire-resistant layer is 0.8mm.

[0012] Furthermore, the upper surface dimensions of the injection-molded board are 608mm × 465mm, and the upper surface dimensions of the fireproof board are 599mm × 457mm.

[0013] Furthermore, the injection-molded board layer is made of ABS material, and the fire-resistant layer is made of fireproof board or ceramic board.

[0014] The beneficial effects of this utility model are:

[0015] This utility model of a flame-retardant desktop board features a fire-resistant layer on the student's contact surface, making it flame-retardant, stain-resistant, and oil-resistant, easy to clean. Compared to injection-molded and wooden desktop boards, it is more wear-resistant, extending its service life. It has a simple structure, is easy to assemble and disassemble, and can be quickly replaced after damage. The desktop color and shape can be freely matched, making it more aesthetically pleasing. It is also easy to process and has low manufacturing costs. Attached Figure Description
