Abstract
The utility model relates to a high-strength double-sided aluminum foil used in the fields of electromechanical and electronic information communication and the like, which comprises aluminum foils, wherein a PET film is arranged between two layers of the aluminum foils, and a layer of bonded adhesive layer is arranged between two sides of the PET film and the aluminum foils. The high-strength double-sided aluminum foil has the following advantages that: firstly, the bonding strength is high, and the peeling strength after bonding is dozens of times even hundreds of times that of the background art; secondly, the heat resistance and the freeze resistance of a plastic film are extremely strong; and thirdly, the high-strength double-sided aluminum foil has double shielding, ternary shielding and insulating functions, and can effectively improve the return losses of circuits in the fields of the electromechanical and electronic information communication and the like.
Description
Technical field
The utility model relates to a kind of two-sided aluminium foil of high strength that is used for fields such as electromechanics, electronic information communication, belongs to composite band and makes the field.
Background technology
CN2889715Y, title " the level and smooth aluminium-plastic tape of ultrathin inferior light ", this aluminium-plastic tape is the aluminium foil base band of 0.12mm～0.05mm by thickness, with surface texture be that the plastic membranous layer of inferior light plucking shape smooth type matsurface is formed, the structure of this inferior light plucking shape smooth type matsurface changes along with variation of temperature, when the plastics temperature on the aluminium foil base band constantly raises more than Vicat softening point, the plastics roughness fades away, and the surface is light frictional resistance face.Its weak point: the one, the adhesive strength between plastic membranous layer and the aluminium foil base band is low; The 2nd, plastic membranous layer hear resistance and cold resistance, and frictional property is difficult to reach the requirement of the two-sided aluminium foil of high strength; The 3rd, the insulation, shield effectiveness is not ideal enough and return loss is big.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly can make adhesive strength height between plastic membranous layer and the aluminium foil base band, heat-resisting, cold-resistant, wearability is good, has the two-sided aluminium foil of the minimum high strength of reliable insulation, shield effectiveness and return loss again.
Design: in order to realize above-mentioned purpose of design.1, adopting the bonding design of bonding glue-line between aluminium foil and the PET film, is major technique feature of the present utility model.The purpose of doing like this is: PET is milky or polymer light yellow, highly crystalline, and surface smoothing is glossy.Have excellent physical and mechanical properties in wider temperature range, long-term serviceability 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, fatigue durability, rub resistance, dimensional stability are all fine.As packaging material PET advantage: 1. the good mechanical performance is arranged, and impact strength is 3～5 times of other films, and folding resistance is good.2. oil resistant, anti-fat, anti-diluted acid, diluted alkaline, anti-most of solvents.3. have good high-and low-temperature resistance performance, can be in 120 ℃ of temperature ranges use for a long time, short-term is used can anti-150 ℃ of high temperature, can anti--70 ℃ of low temperature, and very little to its mechanical performance influence during high and low temperature.4. gas and vapor permeability are low, existing good choke, water, oil and peculiar smell performance.5. transparency height, but shielding of ultraviolet, glossiness is good.6. nontoxic, tasteless, wholesomeness is good.2, adopting the high strength bonding glue-line with aluminium foil and the bonding design of PET film, is two of technical characterictic of the present utility model.The purpose of doing like this is: because the bonding force that produced of high strength bonding glue-line, be not only direct compound tens times of plastic foil and aluminium foil, even hundreds of times, and its overall target has satisfied the requirement of the two-sided aluminium foil of high strength.3, adopting the design of two-sided aluminium foil, is three of technical characterictic of the present utility model.The purpose of doing like this is: because two-sided aluminium foil has the function of double shield, three screens and insulation, it can improve the return loss of circuit in the fields such as electromechanics, electronic information communication effectively.
Technical scheme: the two-sided aluminium foil of high strength, it comprises aluminium foil, is equipped with the PET film between two-layer aluminium foil, is equipped with the bonding glue-line of one deck between PET film two sides and aluminium foil.
The utility model is compared with background technology, and the one, the adhesive strength height, its formed peel strength in bonding back is tens times, hundreds of times of background technology; The 2nd, the hear resistance and the cold resistance of plastic foil are extremely strong; The 3rd, have the function of double shield, three screens and insulation, it can improve the return loss of circuit in the fields such as electromechanics, electronic information communication effectively.
Description of drawings
Fig. 1 is the structural representation of the two-sided aluminium foil of high strength.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.The two-sided aluminium foil of high strength, it comprises aluminium foil 1, and 1 on two-layer aluminium foil is equipped with PET film 3, and 1 on PET film two sides and aluminium foil are equipped with the bonding glue-line 2 of one deck.Described adhesive linkage 2 is the high strength bonding glue-line; Described PET film thickness is optional according to user's needs in 30～40 mu m ranges; Its manufacture craft is that curtain coating rubbing method or heat posted method can and be prior art all, is not described herein at this.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
