Description

Technical Field

[0001] The utility model relates to the technical field of polycarbonate plates, in particular to an antistatic polycarbonate plate. Background Art

[0002] Polycarbonate board is resistant to weak acid. It is made of polycarbonate as the main component and adopts co-extrusion technology CO-EXTRUSION. It shows that PC board is resistant to neutral oil, but not resistant to strong acid, durability, and alkali. It needs to be coated with UV. But it is resistant to high temperature and has good lighting effect. PC sunlight board is made of high-performance engineering plastics---polycarbonate resin. It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardancy, and anti-aging. It is a high-tech, extremely excellent comprehensive performance, energy-saving and environmentally friendly plastic sheet. It is a plastic building material commonly used internationally and has advantages that other building decoration materials cannot match.

[0003] Among them, antistatic polycarbonate sheets are widely used in the construction of clean room plants (semiconductors, LCDs, electronics, optics and medicine, etc.), shielding of clean room equipment, clean room space separation, clean equipment, observation windows and equipment covers, electronic test fixtures, etc.

[0004] Nowadays, most anti-static polycarbonate sheets adopt surface anti-static, that is, a layer of anti-static hard film is formed on the surface of ordinary polycarbonate sheets through coating technology, which can effectively prevent the accumulation of dust and avoid the harm caused by static electricity to meet the special needs of the industry in the high-tech era. However, the interior of the polycarbonate sheet does not have an anti-static structure, and the anti-static film on the surface cannot completely shield static electricity. Part of the charge will still pass through the polycarbonate sheet, and the anti-static performance cannot be further improved. Utility Model Content
