Above-mentioned hollow-particle can be inorganic hollow particle or organic hollow particle, and inorganic hollow particle for example can be
Hollow SiO2.In order to make foam tape that there is preferable buffering and soundproof effect, hollow-particle to account for the weight of the foam glue-line
Percentage is 0.1~30%, if hollow-particle accounts for the weight percent of foamed cotton layer less than 0.1%, the resiliency of foam tape
Can and isolation noise effect it is poor, on the contrary more than 30% when, then the usage amount that can have hollow-particle excessively leads to foamed cotton layer
Adhesion strength decline, it is preferable that the weight percent that hollow-particle accounts for foamed cotton layer is 5~20%.
The partial size of above-mentioned hollow-particle is 1-1000 μm, if partial size less than 1 μm, the sound insulation damping effect of foam tape compared with
Difference, if partial size is greater than 1000 μm, the adhesion strength decline of foamed cotton layer and adhesive phase is obvious, more preferably, above-mentioned hollow grain
The partial size of son is 10~150 μm.
In addition, above-mentioned foamed cotton layer can also contain some auxiliary addition agents, such as dispersing agent, hollow-particle is set to be uniformly dispersed anti-
Only assemble, coupling agent etc..
In foam tape of the invention, foamed cotton layer with a thickness of 0.1mm-2mm；Adhesive phase with a thickness of 50~200 μm.
The present invention also provides a kind of preparation methods of bonding structure, include the following steps:
S1) pretreating agent is coated in by paste layer surface, forms pretreatment layer after solidification,
S2 laminating layer is mutually pasted with by the pretreatment layer on paste layer surface), is chemically reacted, so that the laminating layer
Pass through chemical bonds between the pretreatment layer.
Containing the organic group that can react with laminating layer in above-mentioned pretreating agent, for example, can be unsaturated group, epoxy group,
Amino, isocyanate group, hydroxyl etc., pretreating agent can be using using sprayings, and the modes such as wiping are coated in by paste layer surface.One
In kind of embodiment, pretreating agent is silane, and silane is diluted to 1% with solvent and is contained admittedly, is then coated on by paste layer, 110
DEG C heating 5-10min, formed pretreatment layer.
Above-mentioned steps S2) in, laminating layer can be reacted with reacting for pretreatment layer for UV curing reaction or heat cure, preferably
For heat cure reaction, the condition of heat cure is to place 7 days or 80 DEG C to place 3 days at room temperature.
Above-mentioned steps S2) in, laminating layer further includes foam glue-line and the adhesive phase that foam glue-line or more two sides are arranged in,
Laminating layer the preparation method is as follows:
S21) oligomer of degree of functionality≤3, the monomer of degree of functionality≤3, photoinitiator, hollow-particle are uniformly mixed and are obtained
Foam rubber layer composition is coated with foam rubber layer composition on release film, two-sided to solidify according to UV, forms the foam rubber of semi-solid preparation state
Layer, the UV energy are 2* (200~400) mj/cm2；
S22) oligomer of degree of functionality≤3, the monomer of degree of functionality≤3, photoinitiator are uniformly mixed and obtain adhesive phase
At least contain a kind of active group that can be reacted with pretreating agent in composition, the oligomer and the monomer, by adhesive
Layer composition is coated on side of the foam glue-line far from release film, with 200~400mj/cm2UV energy ultraviolet solidification, shape
The interface of composite adhesives layer, described adhesive layer and the foamed cotton layer passes through chemical bonds；
S23 release film) is removed, in the other side coating adhesive layer composition of foam glue-line, with 200~400mj/cm2
Energy ultraviolet solidification, form adhesive phase, the interface of described adhesive layer and the foam glue-line by chemical bonds,
Form laminating layer.
Above-mentioned steps S21) in, on the one hand since foam glue-line is with 2* (200~400mj/cm2) low energy double-sided illumination
Ultraviolet light solidification, solidification rate is slower, easily formation semi-cured state；On the other hand, due to foam glue-line be only covered on one side from
Type film, there are oxygen inhibition phenomenons in Light Curing for the one side of not set release film, to make unreacted double bond residual volume
More.Two sides are respectively coated adhesive phase above and below above-mentioned foam glue-line, unreacted double bond and bonding in foam glue-line at this time
Double bond in oxidant layer reacts, and forms chemical bond, so that adhesive phase and the interface of foam glue-line be made to pass through chemical bonded refractory
It closes, improves the integral strength of foam tape, avoid the interface unbound due to adhesive phase with foam glue-line and bond
The problem of failure.
Above-mentioned foam glue-line with a thickness of 0.1mm-2mm, thickness is thicker, thus the ultraviolet light of low energy solidification under, instead
Answer rate comparatively slower, foamed cotton layer is in semi-cured state, and surface has viscosity.The double bond of above-mentioned foam rubber layer composition
Conversion ratio is 40~90%, and the double bond reaction of unreacted double bond and adhesive phase forms chemical bond, improve adhesive phase with
The binding force of foam glue-line.
Above-mentioned steps S21) in, it further include being combined before the two-sided photograph UV curing schedule or after step in foam glue-line
The step of release film is covered on object.In the two-sided covering release film of foam rubber layer composition, foam glue-line can be preferably protected, is prevented
Because the phenomenon that stick to each other occurs in the viscosity of foam film surface when only it winds.
In the step S23) after, further include the steps that carrying out EB solidification to laminating layer.EB is cured as electronic beam curing, leads to
It crosses high energy electron and converts free radical for double bond, to crosslink, its main feature is that crosslinking rate is fast, double bond conversion rate is high, and
Glue-line whether light transmission on solidification effect substantially without influence.
High-intensitive foam tape collocation pretreating agent of the invention further increases shearing to being pre-processed by paste layer
Intensity, simultaneously because the bond strength of pretreatment layer and adhesive phase is big, and foam rubber thickness degree is thicker among adhesive tape and contains big
The filler of amount, solidification are difficult completely, so causing to destroy the cohesional failure for glue layer.Therefore, after to step S23)
Laminating layer carries out EB solidification again, can enhance the cohesive force of glue-line, improve shear strength again.
Below with reference to embodiment and comparative example, beneficial effects of the present invention are further illustrated.Obviously, described implementation
