Description
Technical field
The invention 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 interim fixed, the masking, film part in heating process
Deng the purposes such as protection, 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, and without water resistance, part high temperature resistant is double
Most of face adhesive tape uses Kapton to be carrier, and organic silicon pressure-sensitive adhesive is the double-faced adhesive tape of main body,
It is high without water proofing property and price although it can be short of 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 for carrier, two sided coatings Modified Acrylic Ester Pressure Sensitive Adhesive or
Rubber pressure-sensitive adhesive sticks agent, although adhesion strength is than larger, and resistance to elevated temperatures is also preferable, but 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.As shown in figure 1, being 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 is 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, causes 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 high
It is expensive.
The content of the invention
In view of the defect that above-mentioned prior art is present, the purpose of the present invention is to propose to a kind of adhesion strength height, high-low temperature resistant
Performance it is good and again have water resistance the two-sided foam tape of reinforced type, it is cheap, can as electronic applications double faced adhesive tape
Adhesive tape is used.
The purpose of the present invention 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
Constitute；The solvent that the solvent-borne type polyacrylic pressure sensitive adhesive is used 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 then bond the fastness of affixed object not enough, and thickness is also easy to produce larger compacted during glue-line stress if relatively slow higher than solidifying if 70 μm
Become and cause to bond failure, and cost is higher.
Further, first enhancement layer and second enhancement layer are constituted 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
Degree is thickening to 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 constituted；The solvent that the solvent-borne type acrylic pressure sensitive adhesive is used 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
M then the first enhancement layer, the second enhancement layer and foamed cotton layer adhesive fastness not enough, 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, the adhesion strength of foam tape is improved.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 the stress produced by external forces, and 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, all kinds of color schemes can be debugged according to demand.
The present invention protrusion effect be：The invention provides a kind of waterproof foam double-faced adhesive band, water resistance is good, bonds strong
Degree 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, the embodiment to the present invention is described in further detail, so that of the invention
Technical scheme is more readily understood, grasped.
