Problems solved by technology

The common anti-static ceramic-metal composite access floor is made of anti-static ceramic tiles as the surface layer, composite all-steel floor or cement particle board, and is processed with conductive adhesive strips around it. It has stable anti-static performance, high wear resistance, and long life. , high load, good decorative effect, etc., but its weight is relatively large, which has a certain impact on the load bearing of the electrostatic area
The all-steel anti-static access floor adopts highly wear-resistant melamine HPL fireproof board or PVC as the surface layer, and the steel shell structure base material is convenient for construction, installation and replacement. However, its service life is short, it is easy to peel and warp, and it needs to be replaced regularly
[0005] The Chinese invention patent with publication number CN 101402270A discloses a kind of antistatic nano-composite board and its production method. First, the antistatic color glue solution containing epoxy resin, conductive carbon powder, high-temperature nano-synthetic filler, acetone and dyeing agent is prepared, and then Spread the glue evenly on the cut original layer, and bake it at 80-120°C for 1 hour to obtain an anti-static nano-board, which is laminated and pressed to form an anti-static nano-composite board, which can be used for surface mounting, but the original layer is a sheet Shaped structure, it needs to be applied multiple times and then superimposed, formulated and pressed, and the process is complicated

Abstract

The invention discloses an electric conduction board and a manufacture method of the electric conduction board. Body paper after being steeped into melamino-formaldehyde resin undergoes primary drying, and impregnated paper is manufactured. The melamino-formaldehyde resin containing nanoscale conductive carbon black is coated on the surface of the impregnated paper, and secondary drying is performed so as to obtain electric conduction paper. The electric conduction paper and the impregnated paper are respectively pressed on different side surfaces of a flat board main body in a sticking mode, and the electric conduction board is manufactured. The surface of the manufactured electric conduction board is free of the defect of hickie, and blackness is even. Resistance value of the surface is in a range of 1 to 5 megohm. The electric conduction board and the manufacture method of the electric conduction board can be used in a microcomputer console cabinet, a switching room and areas prone to generate friction and release static naturally such as a running machine room.

Description

technical field [0001] The invention relates to an artificial board for decoration, in particular to a conductive board for discharging static electricity in a static electricity generation area and a preparation method thereof. Background technique [0002] Static electricity is an objective natural phenomenon, which has the characteristics of high voltage, low power, small current and short action time. Static electricity can be generated in various ways, such as contact, friction, etc., which will generate static electricity, especially in areas such as microcomputer control rooms, power distribution rooms, and treadmill rooms, where static electricity accumulation is particularly significant. In order to prevent personal electric shock, fire, explosion and electronic device failure and damage caused by the accumulation of static electricity, it is necessary to take effective preventive measures against its adverse effects, such as suppressing the generation of static ele...
