Abstract
The invention discloses a damping adhesive tape which comprises the uppermost layer, an intermediate layer and the lowermost layer, wherein the uppermost layer is a polyester film, the intermediate layer is polytetrafluoroethylene, and the lowermost layer is polyimide. The polyester film accounts for 31-51wt% of the main body of the damping adhesive tape, the polytetrafluoroethylene accounts for 23-36wt% of the main body of the damping adhesive tape, and the polyimide accounts for 23-37wt% of the main body of the damping adhesive tape. The invention provides the damping adhesive tape which has the advantages of good damping performance, chemical resistance, high-temperature resistance and the like.
Description
Technical field
The present invention relates to a kind of adhesive tape, relate in particular to a kind of damping adhesive tape.
Background technology
In normal life, common joint sealing gummed tape (BOPP Biaxially oriented polypropylene film (BOPP)) is indispensable articles for daily use in any enterprise, company, personal lifestyle, but with respect to a current domestic situation, though producer is many, technology is uneven.And domestic adhesive tape industry content is technically also in the very low stage, national also to the clear and definite selection of this neither one.People often to the understanding of adhesive tape in the very muddled stage, think cheap, feel viscosity is good, these are all wrong understanding and judgements in fact.
To how to select the quality of adhesive tape so? in fact, the glue quality of adhesive tape in use has two standards, and one is initial bonding strength, and one is confining force, and both are inversely proportional to.Generally viscous force is that glue covers that to be coated with religion few lower than the adhesive tape of No. 10, generally only has 20 microns of left and right, as stationery adhesive tape, and the adhesive tape of common sales promotion binding use.The initial bonding strength of normal tape is between No. 15-20, and the thickness of this adhesive tape glue generally has 22-28 micron.Standard compliant thickness.But the adhesive tape major part on market all admixture impurity, so thickness increases, for covering impurity, in glue, be also mixed with toner, so that scotch tape has just occurred is yolk yellow, light green, this adhesive tape is all generally inferior.
On tape surface, scribble one deck tackiness agent, could make adhesive tape can cling article, tackiness agent is the earliest from animal and plant, and at 19th-century, rubber is the major ingredient of tackiness agent; Modern times are the various polymkeric substance of widespread use.Tackiness agent can cling thing, is that this bond can stick together molecule firmly due to the intermolecular formation bond of molecule and the wish attachment of itself.The composition of tackiness agent, according to different labels, different sorts, has various polymkeric substance.Thereby cause adhesive tape damping performance poor, the shortcomings such as the strong and non-refractory of resistance to chemical attack.
Summary of the invention
The object of the present invention is to provide a kind of damping adhesive tape, there is good damping property, the advantages such as resistance to chemical attack and high thermal resistance.
Technical scheme of the present invention is: a kind of damping adhesive tape, described damping adhesive tape comprises the superiors, middle layer and orlop, the described the superiors are polyester films, described middle layer is tetrafluoroethylene, described orlop is polyimide, described polyester film accounts for the 31%-51% of damping adhesive tape body weight, and described tetrafluoroethylene accounts for the 23%-36% of damping adhesive tape body weight, and described polyimide accounts for the 23%-37% of damping adhesive tape body weight.
In a preferred embodiment of the present invention, described polyester film comprises polyethylene terephthalate.
In a preferred embodiment of the present invention, described polyester film accounts for 48% of damping adhesive tape body weight, and described tetrafluoroethylene accounts for 27% of damping adhesive tape body weight, and described polyimide accounts for 25% of damping adhesive tape body weight.
A kind of damping adhesive tape of the present invention, has good damping property, the advantages such as resistance to chemical attack and high thermal resistance.
Accompanying drawing explanation
The main TV structure schematic diagram that accompanying drawing 1 is damping adhesive tape one preferred embodiment of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, the superiors, 2, middle layer, 3, orlop.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, Fig. 1 is a kind of damping adhesive tape of the present invention, and described damping adhesive tape comprises the superiors 1, middle layer 2 and orlop 3, and the described the superiors 1 are polyester films, and described middle layer 2 is tetrafluoroethylene, and described orlop 3 is polyimide.
Further illustrate, described polyester film comprises polyethylene terephthalate, and described polyester film accounts for 48% of damping adhesive tape body weight, and described tetrafluoroethylene accounts for 27% of damping adhesive tape body weight, and described polyimide accounts for 25% of damping adhesive tape body weight.Polyester film is a kind of water white transparency, glossiness film, and mechanical property is good, and rigidity, hardness and toughness are high, puncture, rub resistance, high temperature resistant and low temperature, chemical proofing, oil-proofness, resistance to air loss and fragrance protectiveness are good, are one of conventional barrier laminated film base materials.
Further illustrate, described tetrafluoroethylene is a kind of synthetic macromolecular material that has used fluorine to replace all hydrogen atoms in polyethylene.This material has the feature of antiacid alkali resistant, anti-various organic solvents, is dissolved in hardly all solvents.Meanwhile, tetrafluoroethylene has resistant to elevated temperatures feature, and its frictional coefficient is extremely low, so after can making lubrication, also become the desirable coating of easy clean pot and water pipe internal layer.
Further illustrating, described polyimide has good damping performance, the tensile strength of unfilled plastics is all more than 100Mpa, and the film of polypyromelliticimide is more than 170Mpa, and the shock strength of the special thermoplastic polyimide of alliance is moulded up to 261KJ/m2 in Hangzhou.And biphenyl polyimide reaches 400Mpa.As engineering plastics, elastic membrane amount is generally 3-4Gpa, and fiber can reach 200Gpa, and according to Theoretical Calculation, the synthetic fiber of pyromellitic acid anhydride and Ursol D can reach 500Gpa, is only second to carbon fiber.A kind of damping adhesive tape of the present invention, has good damping property, the advantages such as resistance to chemical attack and high thermal resistance.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
