Problems solved by technology

[0002] At present, most of the consumables used for FOG (mounting FPC on the glass panel) binding are traditional silicone skins, which have the following defects during use: a. The thermal conductivity is not good, and the product itself is not anti-static. Static electricity is easy to be generated during the bonding process, resulting in static electricity residue in the product; b. The number of pressing times is small, basically about 20 times, and the refueling is frequent, which delays the time; c. Silicon oil is easy to precipitate, which interferes with the subsequent edge banding process

Abstract

The invention relates to the technical field of liquid crystal display screens, in particular to anti-static heatproof silicone rubber and a manufacturing technology thereof. The anti-static heatproof silicone rubber comprises a base material layer and an anti-static heatproof silicone rubber layer coating on the upper surface of the base material layer, wherein the base material layer is a PI film, and the anti-static heatproof silicone rubber layer comprises, by weight, 96-100 parts of silicone rubber, 0.5-1.5 parts of coloring agent and 0.5-1.5 parts of vulcanizing agent. The anti-static heatproof silicone rubber has the advantages that the anti-static heatproof silicone rubber is faster and more uniform in heat conduction and capable of avoiding the defects of static residues and static puncture; lamination times reach 60-80 times, feeding and discharging time is shortened, and production capacity is increased; without silicone oil precipitation, UV glue edge sealing cannot be affected.
