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
The present invention relates to the treadmill technical field, particularly a kind of conduction running board and manufacturing approach thereof.
Background technology
Running board is the supporting member of treadmill, is fixed on the frame.When people used treadmill to take exercise, pin was trampled on running is with, and the running band moves with the speed of setting, and was run by the running board support and was with, the band sliding and running on running board of running.
It is base material that the running board that present treadmill is attend institute's adapted generally adopts MDF (medium density fibre board (MDF)), surface layer (with the band of running to the face of rubbing) paste the melamine resin impregnated paper.Melamine resin solidifies the back and forms hard, wear-resisting surface, is with bottom fiber to rubbing with running, and coefficient of friction is lower, is generally between the 0.18-0.21.After being coated with lubricant on the fiber of the running board surface or the band bottom of running, can satisfy the normal use of treadmill.Run and be with the fiber of bottom generally to use polyster fibre.Terylene and melamine resin friction very easily produce static.Its electrostatic pressure and surrounding air humidity are inversely proportional to.Be that air humidity is low more, gather electric charge more easily, electrostatic pressure is high more.Static is as far as treadmill, and is very harmful.At first be the operation of disturbing automatically controlled and instrument, make the treadmill cisco unity malfunction: available reluctantly sometimes; Sometimes control malfunctioning; Sometimes clear-cut " strike " is very irritating.When serious even puncture, burn some electronic component, cause machine breakdown; Secondly, lower in humidity, when the speed of service is very fast again, can produce point discharge, abnormally dangerous; Its three, human body is taken exercise on machine, also static electrification causes skin to itch and electric-shock feeling, and sports fun and motion effect are had a greatly reduced quality.
Solve the band of running and produce the means of static with running board to rubbing, the past is on running is with, to inweave conductive fiber, 22D commonly used or 44D.Per 3 ~ 20mm knits one, can significantly electrostatic pressure be lowered.But can not static be eliminated fully.After all, friction is a face, and conductive fiber only is a line.If whole face all inweaves conductive fiber, the one, cost is too high, and the 2nd, other mechanical property does not reach requirement, so unworkable.In order to improve the reliability of treadmill work, must look for countermeasure in addition.
Summary of the invention
The object of the present invention is to provide between a kind of run band and the running board mutually, mutual friction can not produce static, conduction running board safe and reliable to operation.
Technical solution proposed by the invention is such:
A kind of conduction running board comprises the running board substrate, is coated with conductive layer on this running board real estate, and the formula constituent of this conductive layer is counted with weight portion:
Unsaturated polyester resin 100,
Graphite 15 ~ 30,
Cobalt accelerator 0.3 ~ 1.2,
Methyl ethyl ketone peroxide 0.5 ~ 2.
This running board substrate is a medium density fibre board (MDF).
The method step of making said conduction running board is: by above-mentioned formula constituent graphite is sneaked in the unsaturated polyester resin; Disperse with three-roll grinder; The adding cobalt accelerator mixes, and adds to be coated on the running board real estate normal temperature cure after methyl ethyl ketone peroxide mixes again.
Unsaturated polyester resin also is the binding agent of conductive material such as graphite, ethene carbon black, silver powder, aluminium powder powder as the basic material of conduction running board face coat.The first-selected graphite of conductive material, also available other conductive materials such as ethene carbon black, silver powder, aluminium powder, but the electric conductivity of graphite has reached requirement, has the advantage inexpensive, that cost performance is high.Methyl ethyl ketone peroxide is a kind of curing agent.Cobalt accelerator is used to reduce the decomposition temperature of methyl ethyl ketone peroxide, realizes normal temperature cure.The first-selected medium density fibre board (MDF) (MDF) of running board substrate also can be selected glued board for use.
Compared with prior art, the present invention has following remarkable result:
(1) the present invention scribbles one deck conductive layer on the running board face, and its resistivity is 10
5~ 10
6Ω like this, has just thoroughly solved the fricative electrostatic problem between band and the running board of running.
(2) since running board with run that friction does not produce static between the band, also avoided the absorption of static to dust, make running board and run lubricated effective more for a long time between the band, further improve the functional reliability and the durability of treadmill.
(3) with graphite as conductive material, except that having electric conductivity, graphite still is a kind of grease packing, and the running board skin-friction coefficient is reduced, thereby reduces the power consumption of traction electric machine, realizes energy-conservation, low-carbon (LC).
