Abstract

The invention provides a kind of antistatic ground cushion for computer room, including bottom and top layer, it is characterized in that, the bottom uses conductive rubber layer, top layer is the resin bed with antistatic property, the bottom and top layer are bonded to form antistatic ground cushion by the compound mode of heat, and the sheet resistance on the top layer is less than the sheet resistance of the bottom.The mode that top layer and bottom combine causes ground cushion of the present invention to have good antistatic performance, simultaneously because bottom rubber so that warpage, convenient installation are less likely to occur ground cushion of the present invention.

Description

A kind of antistatic ground cushion
The present invention is application number：2015101283445, the applying date：2015-03-23, denomination of invention：One kind is antistaticly The divisional application of pad.
Technical field
The present invention relates to a kind of ground cushion, more particularly to a kind of antistatic ground cushion.
Background technology
In computer room due to a variety of electronic components be present, it is necessary to carry out antistatic process, particularly ground cushion to whole computer room On will anti-fixed-point processing, processing method conventional at present is the PVC pads of electrostatic of being set up defences on ground cushion upper berth, but this PVC pads are Realized by way of adding the antistatic additive such as carbon black wherein it is antistatic, in order to more preferably antistatic effect, just need More antistatic additive are added, but electrostatic agent such as carbon black influences whether PVC intensity after adding excessively, can cause PVC The warpage of pad, it have impact on use of the PVC pads as ground cushion.It can be said that the antistatic property of traditional PVC pads is general, reach Just it is difficult to improve again after certain value.
The content of the invention
In order to solve problem above present in background technology, the invention provides a kind of good ground cushion of anti-static effect.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of antistatic ground cushion, including bottom and top layer, it is characterised in that the bottom uses conductive rubber layer, top layer For the resin bed with antistatic property, the bottom and top layer are bonded to form antistatic ground cushion by the compound mode of heat, institute The sheet resistance for stating top layer is less than the sheet resistance of the bottom.
The metal powder that the bottom accounts for isoprene rubber weight 1.2% by being added in isoprene rubber obtains.
The top layer includes big positioned at middle sandwich layer and the coating positioned at sandwich layer both sides, the sheet resistance of the sandwich layer In the sheet resistance of coating.
The sandwich layer by 77.3% weight than polyethylene terephthalate and the polyaniline of 22.7% weight ratio exist It is polymerized at 235 DEG C；The coating is made up of thermoplastic polyurethane and antistatic additive, the thermoplastic polyurethane by 60.5% weight than polyethylene glycol, 32.8% weight than 4,4 '-di-2-ethylhexylphosphine oxide (phenyl isocyanate) and 6.7% weight 1, the 6- hexylene glycols of ratio polymerisation at 220 DEG C obtains, and the antistatic additive is lithium bromide.
The processing method of the coating is：By polyethylene glycol, 4,4 '-di-2-ethylhexylphosphine oxide (phenyl isocyanate) and 1,6- Hexylene glycol mixes, and then adds and accounts for polyethylene glycol, 4,4 '-di-2-ethylhexylphosphine oxide (phenyl isocyanate) and 1,6- hexylene glycol weight The lithium bromide of sum 1.8%, above-mentioned substance are added to extruder and polymerize at a high temperature of 220 DEG C, then will be squeezed using comminutor Go out the resin polymerizeing in machine to be granulated, pellet is then molded into sheet with injection molding machine
The features of the present invention or beneficial effect are：
The mode that top layer and bottom combine causes ground cushion of the present invention to have good antistatic performance, simultaneously because bottom Layer rubber so that warpage, convenient installation are less likely to occur ground cushion of the present invention.
Embodiment
With reference to embodiment, the invention will be further described：
Embodiment 1
A kind of antistatic ground cushion, including bottom and top layer, the bottom is using conductive energy and has certain elasticity Conductive rubber layer, bottom and top layer are bonded together into antistatic ground cushion by the compound mode of heat.
The metal powder that the bottom accounts for isoprene rubber weight 1.2% by being added in isoprene rubber obtains.
The top layer is included positioned at middle sandwich layer and the coating positioned at sandwich layer both sides, and the sandwich layer is by 77.3% weight The polyaniline of the polyethylene terephthalate of ratio and 22.7% weight ratio is polymerized at 235 DEG C, the coating by Thermoplastic polyurethane and antistatic additive composition, the thermoplastic polyurethane by 60.5% weight than polyethylene glycol, 32.8% weight 1, the 6- hexylene glycols of the 4 of amount ratio, 4 '-di-2-ethylhexylphosphine oxide (phenyl isocyanate) and 6.7% weight ratio polymerisation at 220 DEG C Obtain, the antistatic additive is lithium bromide.Specifically method is：By polyethylene glycol, 4,4 '-di-2-ethylhexylphosphine oxide (phenyl isocyanic acid Ester) and 1,6- hexylene glycol mixing, then add and account for polyethylene glycol, 4,4 '-di-2-ethylhexylphosphine oxide (phenyl isocyanate) and 1,6- oneself The lithium bromide of glycol weight sum 1.8%, above-mentioned substance are added to extruder and polymerize at a high temperature of 220 DEG C, then using making The resin polymerizeing in extruder is granulated by grain machine, and pellet then is molded into sheet with injection molding machine.The making of sandwich layer Using same method.
The sandwich layer and coating made according to the method described above, the sheet resistance of coating are greater than the sheet resistance of sandwich layer, The relatively single sandwich layer in the top layer so formed or single coating have more preferable electric conductivity, i.e., with more preferable antistatic Effect.
Conducting performance test is carried out to bottom, sandwich layer, coating, superficial layer respectively, there is following result：
Sheet resistance (Ω)
Bottom 3.6×1010
Sandwich layer 5.3×107
Coating 3.1×107
Superficial layer 2.8×107
Whole ground cushion 2.6×107
It can be seen that after using ground pad structure of the present invention, the antistatic effect of whole ground cushion will be better than single bottom The antistatic property of layer or sandwich layer.It can be seen that ground cushion of the present invention has excellent electrostatic dissipative properties.
It will be recognized by those skilled in the art, can be to above-mentioned on the premise of without departing from protection scope of the present invention Embodiment carries out various modifications, change and combination, and thinks that this modification, change and combination are the models in originality thought Within enclosing.
