Embodiment 1
[0021] A conductive running board is composed of a running board substrate and a conductive layer covering the substrate surface, and the formula ingredients (parts by weight) of the conductive layer are:
[0022] Unsaturated polyester resin 100,
[0023] graphite 22,
[0024] Cobalt Accelerator 0.7,
[0025] methyl ethyl ketone peroxide 1.2.
[0026] The method steps for manufacturing the conductive running board are as follows: mix the graphite powder into the unsaturated polyester resin according to the above formula components, disperse it with a three-roll mill, add a cobalt accelerator and mix it evenly, then add methyl ethyl ketone peroxide and mix it evenly, and then apply it on the The MDF surface is cured at room temperature to make a conductive running board. The resistivity of this conductive running board is 10 5 ~10 6 Ω.

Abstract
The invention discloses a conductive run board and a manufacturing method thereof. No static electricity is generated even if a running belt and the run board mutually rub, so that the conductive run board is safe and reliable to operate. The conductive run board is characterized in that the substrate surface of the run board is covered with a conductive layer. The formula of the conductive run board comprises the following raw materials in parts by weight: 100 parts of unsaturated polyester resin, 15-30 parts of graphite, 0.3-1.2 parts of cobalt promoting agent and 0.5-2 parts of methyl ethyl ketone peroxide. The manufacturing method of the conductive run board comprises the following steps: according to the above formula components, mixing the graphite into the unsaturated polyester resin; dispersing by a three-roll grinder; adding the cobalt promoting agent to evenly mix; then adding the methyl ethyl ketone peroxide to evenly mix; coating on the substrate surface of the run board; and curing at normal temperature.
Description
technical field [0001] The invention relates to the technical field of treadmills, in particular to a conductive treadmill and a manufacturing method thereof. Background technique [0002] The running board is the supporting member of the treadmill and is fixed on the frame. When people use the treadmill to exercise, their feet step on the running belt, and the running belt runs at a set speed. The running board supports the running belt, and the running belt slides on the running board. [0003] The running boards used on current treadmills generally use MDF (medium density fiberboard) as the base material, and the surface layer (the friction surface with the running belt) is pasted with melamine formaldehyde resin impregnated paper. After curing, the melamine formaldehyde resin forms a hard and wear-resistant surface, which rubs against the bottom fiber of the running belt, and the friction coefficient is low, generally between 0.18 and 0.21. After the lubricant is appli...
