STATIC-DISSIPATIVE COMPOSITION AND PANEL MANUFACTURED THEREWITH

摘要

Disclosed is an electroconductive composition for dissipating electricity, which comprises a binder, a quick-curing, high strength admixture, an expansion agent, an electroconductive material, a chemical admixture, and a hardening accelerator, said electroconductive material being finely milled, pan- or pitch-type carbon fiber with a length from 100 to 1,000 mu m and being used in the amount of 0.1 to 20 % by weight. In addition to being so excellent in scattering static electricity as to ensure uniform surface resistance, the electroconductive composition is very convenient to work with because of its high fluidity. Further, the composition is endowed with such a self-leveling property as to require no additional finishing processes. It can be formed into a layer as thin as 5 mm, which rsults in a significant reduction in material cost. With these advantages, the composition can find application in various fields. A panel prepared with the composition is also disclosed.
