Description
Technical field
The utility model belongs to tape technology field, more particularly to a kind of waterproof foam double-faced adhesive band.
Background technology
With making rapid progress for electronic product, to the performance requirement more and more higher of double-faced adhesive tape, especially height is bonded
Intensity, high and low temperature resistance, water resistance etc..High and low temperature resistance generally refers to ensure quilt under high temperature or low temperature environment
Viscous thing does not fall off and has certain peel strength.Water resistance is primarily referred to as preventing water from bonding gusset from double faced adhesive tape and penetrating into,
Performance impact is caused to product.This high-low temperature resistant Waterproof double sticky tape is widely used, available for engineering machinery, automobile instrument panel
Seal foaming pad, washing machine sealing gasket etc., also in the various production technologies of digital product electronic component, engraving plate or face
The stickup of plate and part, especially because its heat resistance, available for the interim fixed, masking in heating process, film part
Deng protection, the purposes such as conveying, be also applied to high-temperature insulation protection, reinforcement protection of the industries such as electronic apparatus, instrument etc..
At present, two-sided tape is more based on normal temperature double-faced adhesive tape on the market, double without water resistance, part high temperature resistant
It is carrier that most of face adhesive tape, which uses Kapton, and organic silicon pressure-sensitive adhesive is the double-faced adhesive tape of main body,
Although it can be short of, held high without water proofing property and price with resistance to more than 150 DEG C of high temperature on bonding force and contaminative
It is expensive；Also there is part high temperature resistant double-faced adhesive tape to use PET film as carrier, two sided coatings Modified Acrylic Ester Pressure Sensitive Adhesive or
Rubber pressure-sensitive adhesive sticks agent, although adhesion strength is bigger, resistance to elevated temperatures is also preferable, does not have water resistance equally.
In the market water-resistant type two-sided tape, it is common that using PE foams as carry base, two sided coatings rubber-type adhesive, silica gel or
Acrylic pressure sensitive adhesive forms.As shown in figure 1, it is conventional double-faced adhesive tape structure schematic diagram, in the both sides of PE/PET foamed cotton layers 12
Coated with acrylic pressure sensitive glue-line 11 and 13, the side of acrylic pressure sensitive glue-line 13 are fitted with off-style paper layer 14.Water resistance all compares
Well, adhesion strength is high, and adhesive high and low temperature resistance is also good, but because foam is foaming structure, inside is containing many micro-
Hole, cause foam intensity decreases itself, especially in the case of a high temperature, foam intensity decreases itself it is more serious, have impact on bubble
The overall adhesion strength of cotton two-sided tape.3M production Waterproof double sticky tape --- VHB adhesive tapes, whole glue-line be it is integral, no
Containing any load base, there are many hole-closing structures inside colloid, adhesion strength is high, and resistance to elevated temperatures is good, and water resistance is excellent, but price is held high
It is expensive.
Utility model content
In view of the defects of above-mentioned prior art is present, the purpose of this utility model is to propose that a kind of adhesion strength is high, resistance to height
Low temperature performance well and the two-sided foam tape of reinforced type with water resistance, it is cheap, can be as the double of electronic applications
Face adhesive tape uses.
The purpose of this utility model will be achieved by the following technical programs：
A kind of waterproof foam double-faced adhesive band, successively including release layer, the first pressure-sensitive adhesive layer, the first enhancement layer, first is flexible
Pressure-sensitive adhesive layer, foamed cotton layer, the second flexible pressure-sensitive glue-line, the second enhancement layer, the second pressure-sensitive adhesive layer.
Further, first pressure-sensitive adhesive layer and second pressure-sensitive adhesive layer are by solvent-borne type polyacrylic pressure sensitive adhesive
Form；The solvent that the solvent-borne type polyacrylic pressure sensitive adhesive uses is organic solvent butyl oxide, methylisobutylketone, propane diols first
Ether, propylene glycol methyl ether acetate, propylene-glycol ethyl ether acetate, ethyl acetate, butyl acetate, ethyl lactate, methyl acetoacetate,
One or more in methyl acetoacetate；The thickness of first pressure-sensitive adhesive layer and second pressure-sensitive adhesive layer is respectively 25 μm
~60 μm.Solvent-borne type polyacrylic pressure sensitive adhesive, cohesive force is strong, and resistance to elevated temperatures is good, and thickness is 25 μm~60 μm, and thickness is less than
25 μm of fastness for then bonding affixed object are inadequate, and thickness is also easy to produce larger compacted if relatively slow higher than solidifying if 70 μm, during glue-line stress
Become and cause to bond failure, and cost is higher.
Further, first enhancement layer and second enhancement layer are formed by PET film, and its thickness is 10 μm~25
μm.The thickness of PET film is in 10 μm~25 μ ms, and being primarily due to thickness can cause base material excessively thin less than 10 μm, existing life
Production. art is difficult reply, and thickness can then cause foam double-faced adhesive band resistance to warpage to be deteriorated more than 25 μm, meanwhile, because base material is thick
Spending thickening can cause rise in price.
Further, the PET film is two-sided corona base material, and surface tension is more than or equal to 50 dynes.
Further, the first flexible pressure-sensitive glue-line and the second flexible pressure-sensitive glue-line are by solvent-borne type acrylic pressure
Quick glue is formed；The solvent that the solvent-borne type acrylic pressure sensitive adhesive uses is organic solvent butyl oxide, methylisobutylketone, propane diols first
Ether, propylene glycol methyl ether acetate, propylene-glycol ethyl ether acetate, ethyl acetate, butyl acetate, toluene, one kind in dimethylbenzene or
It is a variety of；The first flexible pressure-sensitive glue-line and the second flexible pressure-sensitive bondline thickness are respectively 5 μm~25 μm, and thickness is less than 5 μ
The adhesive fastness of m then the first enhancement layer, the second enhancement layer and foamed cotton layer is inadequate, thickness be more than 25 μm then strain relief layer because
Stress meeting overrelaxation, causes bonding defect and cost is higher.
Further, the foamed cotton layer is made up of PE foams, and the coefficient of foaming of the PE foams is 3~5, and its thickness is
150 μm~250 μm.The foamed cotton layer is made up of PE foams, and it is closed-cell foam structure, and abscess is fine and close, and tensile strength is big, makes
During, stress can be effectively discharged, improves the adhesion strength of foam tape.PE foamed cotton layers are closed-cell foam structure, foaming
Multiple is 3~5, and less than 3 buffering effects are weak, and sound absorption qualities and heat-proof quality are deteriorated, and higher than 5 cohesive strengths are poor, are being made
The tear of PE foams is easily caused during foam double-faced adhesive band use；Its thickness is 150 μm~250 μ ms, because thickness is less than
150 μm possibly can not effectively discharge because of external forces and caused by stress, base material or glue-line can be caused to destroy, and thickness exceedes
250 μm can cause PE foamed cotton layers caused by high temperature or external forces are excessive creep and be permanently deformed.PE foams are not limited to routine
Color such as white, black, can debug all kinds of color schemes according to demand.
Prominent effect of the present utility model is：The utility model provides a kind of waterproof foam double-faced adhesive band, water resistance
Good, adhesion strength is high, while high temperature resistant and cryogenic property are good, and cost of manufacture is cheap, can be with steady production.
Just accompanying drawing in conjunction with the embodiments below, is described in further detail to specific embodiment of the present utility model, so that this
Utility model technical scheme is more readily understood, grasped.
