The utility model discloses an electronic adhesive tape, which comprises a PET (polyethylene terephthalate) thin film substrate layer, a first polyacrylate pressure-sensitive adhesive layer, a second polyacrylate pressure-sensitive adhesive layer and an MOPP (macromolecule polypropylene) release film, wherein the upper surface of the PET thin film substrate layer is coated with the first polyacrylate pressure-sensitive adhesive layer; the lower surface of the PET thin film substrate layer is coated with the second polyacrylate pressure-sensitive adhesive layer; and the MOPP polypropylene release film is compounded on the lower surface of the second polyacrylate pressure-sensitive adhesive layer. The electronic adhesive tape can overcome the defects of poor transparency, poor moisture resistance, high possibilities of generating raw edges and paper scraps and the like in the prior art, thereby achieving the advantages of favorable transparency, good moisture resistance and low possibilities of generating the raw edges and the paper scraps.

Description

A kind of electronics adhesive tape

Technical field

The utility model relates to the adhesive material between industrial electronic electrical equipment (as computer, mobile phone, digital camera and the LCD etc.) assembly, particularly, relates to a kind of electronics adhesive tape.

Background technology

At present, cross cutting type industrial electronic adhesive tape has substituted assemblies such as screw, bolt and has fixed on electronic apparatus, for the spatial saving, and the saving of cost, and positive effect has been played in the popularization in people's life.

But, above-mentioned coventional type double sticky tape, because the anchor on Ge Laxin base stock surface own causes the adhesive tape transparency not enough, and the Ge Laxin base stock is subjected to humidity effect and produces paper scrap to pollute when the processing cross cutting easily.

As seen, in realizing process of the present utility model, the contriver finds to exist at least in the prior art transparent poor, moisture resistance difference and the easy defectives such as burr and paper scrap that produce.

Summary of the invention

The purpose of this utility model is, at the problems referred to above, proposes a kind of electronics adhesive tape, and is good with realization transparency, moisture resistance is good and the advantage that be difficult for to produce burr and paper scrap.

For achieving the above object, the technical solution adopted in the utility model is: a kind of electronics adhesive tape, comprise PET polyester film substrate layer, be coated in the first polyacrylate pressure-sensitive layer of described PET polyester film substrate layer upper surface, be coated in the second polyacrylate pressure-sensitive layer of described PET polyester film substrate layer lower surface, and the release rete of MOPP that is compound in the described second polyacrylate pressure-sensitive layer lower surface.

Further, the release rete of described MOPP is the release rete of red MOPP.

The electronics adhesive tape of each embodiment of the utility model, owing to comprise PET polyester film substrate layer, be coated in the first polyacrylate pressure-sensitive layer of PET polyester film substrate layer upper surface, be coated in the second polyacrylate pressure-sensitive layer of PET polyester film substrate layer lower surface, and the release rete of MOPP that is compound in the second polyacrylate pressure-sensitive layer lower surface; Wherein, PET polyester film substrate layer has the transparency height, proof voltage is good, the heatproof shrinkability is little and the advantage of long service life; The polyacrylate pressure-sensitive layer has that bounding force is strong, humidity, high temperature resistant good advantage; Be compound in the release rete of MOPP on the polyacrylate pressure-sensitive layer and have that planarization is good, very property is good, off-type force is light, be easy to cross cutting processing and do not have burr, paper scrap produces, the advantage of non-environmental-pollution; The transparency is poor, moisture resistance difference and the defective that easily produces burr and paper scrap thereby can overcome in the prior art, and is good with realization transparency, moisture resistance is good and the advantage of difficult generation burr and paper scrap.

Other features and advantages of the utility model will be set forth in the following description, and, partly from specification sheets, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in the specification sheets of being write, claims and accompanying drawing.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Description of drawings

Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification sheets, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the structural representation according to the cross section view of the utility model electronics adhesive tape.

In conjunction with the accompanying drawings, Reference numeral is as follows among the utility model embodiment:

The 1-first polyacrylate pressure-sensitive layer; 2-PET polyester film substrate layer; The 3-second polyacrylate pressure-sensitive layer; The release rete of the red MOPP of 4-.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

According to the utility model embodiment, provide a kind of electronics adhesive tape.As shown in Figure 1, present embodiment comprises PET polyester film substrate layer 2, be coated in the first polyacrylate pressure-sensitive layer 1 of PET polyester film substrate layer 2 upper surfaces, be coated in the second polyacrylate pressure-sensitive layer 3 of PET polyester film substrate layer 2 lower surfaces, and the release rete of MOPP that is compound in the second polyacrylate pressure-sensitive layer, 3 lower surface.

Here, the polyethylene terephthalate chemical formula is COC ₆H ₄COOCH ₂CH ₂0, English polyethylene terephthalate by name is called for short PET; PET is oyster white or polymkeric substance light yellow, highly crystalline, and surface smoothing is glossy.Have excellent physical and mechanical properties in wide temperature range, the life-time service temperature can reach 120 ℃, and electrical insulating property is good, even under the high temperature high frequency, its electrical property is still better, but corona resistance is relatively poor, creep resistance, resistance to fatigue, rub resistance, dimensional stability are all fine.

Preferably, in the above-described embodiments, the release rete of MOPP can be the release rete 4 of red MOPP.
