Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model provides a grid sticky tape, include waterproof layer 1, substrate layer 2, antistatic adhesive layer 3, exhaust layer 4, from type rete 5 that from the top down set gradually, substrate layer 2 is for alternate high strength polyester fiber cloth 22 that has glass fiber 21, waterproof layer 1 hot pressing complex is in the surface of substrate layer 2, antistatic adhesive layer 3 shaping on the internal surface of substrate layer 2, the exhaust layer sets up in antistatic adhesive layer 3's internal surface and leaves between type rete 5, laminate from type rete 5 and exhaust layer 4, exhaust layer 4 for having latticed or striation's inviscid coating.

The waterproof layer 1 is a polytetrafluoroethylene film which is small in surface tension, free of water, good in water repellency and waterproof performance and good in insulativity, and the polytetrafluoroethylene film is compounded on the outer surface of the high-strength polyester fiber cloth 22, so that the anti-aging and corrosion-resistant performance can be effectively improved.

The high-strength polyester fiber cloth layer is arranged on the substrate layer 2, the glass fibers 21 are inserted into the high-strength polyester fiber cloth layer in a penetrating mode, the glass fibers form a grid shape, the high-strength polyester fiber cloth layer has high flexibility, the substrate layer is made to have air exhaust performance, air exhaust is effectively conducted, the thickness of the substrate layer 2 is 0.05-0.45mm, and the structure of the substrate layer is shown in figure 2.

Prevent that static glue film 3 is antistatic pressure sensitive adhesive, prevent that static glue film 3 is antistatic organosilicon pressure sensitive adhesive layer, organosilicon pressure sensitive adhesive has good temperature toleration, can avoid appearing overflowing gluey and fused problem in high temperature processing procedure, has further promoted the temperature resistance of whole sticky tape, and the glue film itself possesses antistatic effect simultaneously, can avoid stripping voltage's production, can further eliminate static. The peel force is in the range of 500 to 800gf/inch, the thickness is in the range of 0.01 to 100 μm, and the preferable thickness is 15 μm.
