The technical solution of the utility model is achieved in that
A kind of antistatic silica gel pad, comprising:
Basic unit;
Top layer, is covered in described basic unit side, and comprise central core and be coated on the clad outside described central core, the sheet resistance of described clad is less than the sheet resistance of described central core;
Cushion, is covered in side, described top layer, and the sheet resistance on described top layer is less than the sheet resistance of described cushion;
Wherein, the sheet resistance on described top layer is less than the sheet resistance of described basic unit.
Preferably, described basic unit is conductive rubber layer.
Preferably, described top layer is layer of silica gel, and described cushion is layer of silica gel.
Preferably, described top layer is ionic silver layer of silica gel, and described cushion is ionic silver layer of silica gel.
Further, antistatic silica gel pad described in the utility model, also comprises:

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in figures 1 to 6, a kind of antistatic silica gel pad described in the utility model, comprising:
Basic unit 1;
Top layer, is covered in basic unit 1 side, the clad 3 comprising central core 2 and be coated on outside central core 2, and the sheet resistance of clad 3 is less than the sheet resistance of central core 2;
Cushion 4, is covered in side, top layer, and the sheet resistance on top layer is less than the sheet resistance of cushion 4;
Wherein, the sheet resistance on top layer is less than the sheet resistance of basic unit 1.
Antistatic silica gel pad described in the utility model, the structure on basic unit 1 and top layer, makes it to have good antistatic performance; Static elimination time is considered in the setting of cushion 4, too fast when a static electricity is discharged, is less than 0.1 second, can produce electrostatic recoil effect; Static elimination time is excessively slow, is greater than 2 seconds, and static discharge speed is less than the speed that electrostatic produces, and electrostatic can add up, and produces higher electrostatic.Owing to arranging cushion 4 at the lateral surface on top layer, electrostatic is made to be between 0.1 second to 1.8 seconds by the time that cushion 4 discharges, so both can eliminate electrostatic recoil effect, the cumulative effect of electrostatic can be eliminated again, guarantee the safety of electronic devices and components, electronic product.
