The arrangement greatly enhances the wear resistance, tensile strength, high temperature resistance and corrosion resistance of the PET film body through the first reinforcing layer, the second reinforcing layer, the supporting rubber block and the fixing groove, has a stable structure, and is favorable for prolonging the service life of the PET film body; the melamine resin wear-resistant layer is beneficial to enhancing the wear resistance of the PET film body and improving the durability of the PET film body; through first antistatic coating and second antistatic coating, can eliminate the static that the PET film body produced, prevent potential dangers such as electric shock, discharge that the static accumulation leads to, pollution, dust that also can prevent the static accumulation and lead to etc..

Preferably, the first reinforcing layer and the second reinforcing layer are both substrates composed of a silica gel film layer and a glass fiber layer, and the silica gel film layer and the glass fiber layer are fixedly bonded.

This setting is passed through silica gel film layer and glass fiber layer, has strengthened the abrasion strength and tensile strength, the high temperature resistant corrosion resistant of PET film body greatly, and the structure is firm, is favorable to prolonging the life of PET film body.

Preferably, the supporting rubber blocks are uniformly distributed on the first reinforcing layer.

This setting carries out firm support to first back up coat and second back up coat, has strengthened connection structure's intensity, and then is convenient for carry out elastic support to the PET film body, avoids the unexpected pressure loss of PET film body in the use, and the protection is good.

Preferably, the second reinforcing layer is provided with a fixing groove which is matched and connected with the supporting rubber block.

This setting supports in the gluey piece inserts the fixed slot, makes its connection structure more firm.

Preferably, a second antistatic coating is arranged between the melamine resin wear-resistant layer and the second reinforcing layer.

The melamine resin wear-resistant layer enhances the wear resistance of the PET film body and improves the durability; in addition, through the first antistatic coating and the second antistatic coating, static electricity generated by the PET film body can be eliminated, potential risks such as electric shock and discharge caused by static electricity accumulation can be prevented, and pollution, dust and the like caused by static electricity accumulation can also be prevented.
