[Industrial Application Field] The present invention relates to a curable pressure-sensitive adhesive tape that normally has the initial tack and cohesive force of a normal pressure-sensitive adhesive tape, but whose shearing force increases significantly when heated and pressurized. It is. More specifically, after the particulate non-hardened thermosetting resin dispersed in the adhesive layer applies the adhesive tape between adherends,
A thermosetting type that locally cures when heated and pressurized to form strong adhesive and frictional forces between adherends, forming an adhesive layer with excellent shear resistance even under heat and pressure. This invention relates to pressure-sensitive adhesive tapes. [Technical background] For example, when double-sided adhesive tape is applied to the surface of a steel plate that is physically fixed vertically and combined with a glass plate, the double-sided adhesive tape receives shearing force due to the weight of the glass.
As time passes, it gradually begins to shift and eventually falls. This is generally further accelerated at high temperatures. This phenomenon occurs with adhesives used in pressure-sensitive adhesive tapes, such as rubber-based adhesives whose main components are natural rubber or synthetic rubber, and resin-based adhesives whose main components are acrylic acid and acrylic esters. Even if cross-linked, it is inevitable that it retains its rubber-like elasticity and has so-called room-temperature fluidity, and when strong shearing force or heat is applied from the outside, the adhesive layer will shift due to the flow of the adhesive, and eventually It has the disadvantage of being destructive. On the other hand, it is possible to use a thermosetting resin such as epoxy resin for this purpose, but this method requires fixing the bonded area with another method until the curing reaction is completed. Furthermore, due to the curing shrinkage phenomenon that occurs during curing, there are drawbacks such as cracking on adherends such as glass, which has a small expansion coefficient and is brittle. Furthermore, there are methods that use hot-melt adhesives such as EVA, but the adhesive layer softens when heated, causing the same concerns as when using adhesives. [Structure of the Invention] The present invention uses thermosetting resin powder, which is normally incompatible with the adhesive, with an average particle size of 50 to 300 mesh and a hardness (Barcol) of 45 to 150 after curing, to the solid substance of the adhesive. This thermosetting pressure-sensitive adhesive tape is prepared by coating at least one side of a base material with a pressure-sensitive adhesive containing 5 to 90% by weight of the base material. The present inventor has arrived at the present invention as a result of various studies aimed at improving the drawbacks of the conventional adhesives or adhesive tapes. Usually, the idea of mixing an uncured thermosetting resin in an adhesive is proposed as a tackifying effect on the curable resin, but in reality, it is difficult to mix the adhesive with a low molecular weight curing resin due to compatibility. This method involves problems in terms of compatibility and stability of the mixture. In addition, even if the two are forcibly dispersed in this system, the thermosetting resin and curing agent will disperse and inhibit curing, and in some cases, the adhesive will also be incorporated into the curing system, causing problems over time. There is no point in mixing them because the change may cause them to lose their normal adhesive properties, or the cured product will have uniform physical properties and will only exhibit adhesive-like or cured resin-like properties depending on the mixing ratio. The present invention disperses thermosetting resin powder that is incompatible with the uncured adhesive in the adhesive applied to the tape, and the thermosetting resin powder is dispersed in the adhesive without impairing the tackiness of the adhesive under normal conditions. This is a curable pressure-sensitive adhesive tape characterized by the presence of a resin and the adhesive system being heated and pressurized to cure the dispersed thermosetting resin, thereby exhibiting a synergistic adhesive effect. Specifically, it is contained in a pressure-sensitive adhesive in a proportion of 5 to 90% by weight, has an average particle size of 50 to 300 mesh, and has a hardness (Barcol) of 45 to 150 after curing, and is incompatible with the adhesive under normal conditions. This is an adhesive tape made by applying an adhesive containing uncured thermosetting resin powder having certain properties to one or both sides of a base material. Thermosetting powder resin in an uncured state generally has poor compatibility with adhesives, so particles themselves or particle aggregates exist discontinuously in the adhesive, and the surface of the adhesive tape has a more fluid adhesive layer. Because the particles are exposed, the adhesive performance is not impaired, and even if some particles are exposed, the effect is only slight. An adhesive tape coated with an adhesive containing thermosetting resin powder is applied between adherends, and when heated and pressurized, the adhesive flows under pressure in the adhesive layer and becomes a solid. A certain particle hardens and becomes a hardened mass. At this time, at least the adhesive surface directly contacts the adherend surface, and the particle mass hardens discontinuously in the adhesive layer and is adhesively fixed. be done. At this time, the minute particles do not come into contact with the adherend, but form hardened lumps independently or in blocks in the adhesive layer, contributing to the generation of frictional force. Furthermore, these hardened lumps may break through the base material or come out of the weave to form an adhesive layer containing the hardened lumps on the opposite side of the base material. The cured adhesive layer thus formed exhibits a strong adhesive force in which the cohesive force of the adhesive and the adhesive force of the cured resin overlap, and also exists discontinuously. Because it is a hardened mass with a constant hardness, it exhibits a large frictional force between adherends under pressure, and exhibits extremely high shear resistance. Furthermore, thermosetting resins are generally accompanied by a curing shrinkage phenomenon when they cure, but in this curing system, the cured resin is discontinuous with respect to the adherend, so the stress on each bonding surface remains extremely small. , damage caused by curing shrinkage remains to a minimum. The pressure-sensitive adhesive constituting the curable pressure-sensitive adhesive tape that exhibits such effective effects is a normal rubber-based adhesive whose main component is natural rubber or synthetic rubber, or a resin-based adhesive whose main component is acrylic ester. is used. The thermosetting resin powder blended in this pressure-sensitive adhesive in a range of 5 to 90% by weight can be any thermosetting resin that can be made into powder, such as polyester resin, epoxy resin, or phenol resin. If possible, it is desirable that the adhesive be at least normally incompatible with the adhesive in which it is dispersed. This powdered resin has the aforementioned main ingredients as well as a hardening agent, coloring agent, and
It is preferably powdered with a flow control agent/filler by a known method in an uncured state and has a hardness (Barcol) of 45 to 150 after curing, and one with a hardness of 45 or less after curing is sufficient. If the hardness after curing is 150 or more and cannot exert sufficient frictional force, there is a risk that the adherend itself will be destroyed when it is pulled beyond the adhesive force of the adhesive layer. The average particle size of this powder resin is selected from a range of 50 to 300 mesh. If the particle size is less than 50 mesh, the particle size is too large and it is not practical due to the occurrence of curls when it is made into a tape. If the particles are smaller than the above, there is a possibility that the adhesion and frictional effects will not be sufficiently exhibited. This thermosetting resin powder is blended into the above-mentioned adhesive, but when the content of uncured thermosetting resin powder in the adhesive layer is 5% by weight or less, the adhesive strength of the thermosetting resin is If the amount exceeds 90% by weight, the initial adhesive properties will deteriorate, making it impractical as a pressure-sensitive adhesive tape. The base material supporting the adhesive containing such curable resin powder is polyester, polypropylene,
Nonwoven fabrics can be made of plastic films such as nylon, polyethylene, and vinyl chloride, metal foils such as aluminum, copper, and iron, and natural, synthetic, and inorganic fibers such as cotton, polyester, and glass. The above-mentioned adhesive layer is formed on one or both sides of the material. Although the adhesion and frictional effects of the present invention are effective even when coated on only one side for the reasons mentioned above, the effects are remarkable when double-sided tape is coated on both sides. Furthermore, when the present adhesive layer is formed on only one side, the effects of the present invention will not be impaired even if a normal adhesive or hot-melt adhesive is applied to the opposite side. A specific application of a curable adhesive tape that exhibits such useful properties is, for example, as an explosion-proof treatment applied to the outer surface of cathode ray tubes used in televisions, etc., to create complex surface shapes. When using the tape of the present invention to bond the outside glass surface and a metal body, it can first be pasted or wrapped at the desired location without damaging the glass surface, and then 100~ A metal band heated to 500℃ or similarly heated is tightened or fitted, and the heat and pressure completes the curing and adhesion of this tape. Between cathode wires that have been subjected to such explosion-proof treatment, even if a metal body is applied to the inclined part, the hardened adhesive layer made of tape will compensate for the shear force exerted on the inclined surface by the clamping pressure of the metal body. Since the frictional force is sufficient to resist, it prevents displacement even in heated conditions, and at the same time, the curing shrinkage force is dispersed, providing stable explosion-proof performance without causing extreme strain on the glass surface. I can do it. Furthermore, even if this cathode ray tube were to implode, there is effective adhesion between the metal body and the glass, so there is no fear of fragments flying off, and other excellent effects can be achieved. This effective thermosetting pressure-sensitive adhesive tape can also be used for applications that apply shear force and heat at the same time to plastics, metals, inorganic materials, etc., but it is especially applicable to materials such as ceramics, ferrite, and glass. It exhibits a remarkable effect in adhesive applications where a large shearing force is applied under normal or heated conditions to an adherend having a small coefficient of expansion and a small coefficient of surface friction. Examples and application examples of the present invention are shown below, but it goes without saying that the present invention is not limited to these application examples. Example A semi-cured resin made of 100 parts by weight of a bisphenol A type epoxy resin with an epoxy equivalent of 185 and 30 parts by weight of 4,4'-diaminodiphenylsulfone was melted at 140°C for 2 hours and then cooled. 200 mesh pass of thermosetting resin powder was taken out, and an adhesive solution was prepared by mixing this powder with a butyl polyacrylate pressure sensitive adhesive at a concentration of 25% by weight. The hardness (Bacall) of the semi-cured resin was 85 when it was cured at 160°C for 2 hours. Pour this adhesive solution into a vat, apply it to both sides of a 50μ thick polyester film that has been subjected to double-sided electrical discharge treatment so that the final adhesive layer will be 50μ thick, roll it up with release paper, and cure. A pressure-sensitive adhesive tape was produced. The surface of this adhesive tape is rough and has a slight initial tack property.
The properties after time curing are as shown in Table 1, and a remarkable improvement in the effect of curing was observed not only at room temperature but also under heating conditions. In addition, no cracks or chips, which are commonly seen with ordinary epoxy resins, were observed in glass or ferrite, proving the practicality of the present invention in dispersing the curing shrinkage force.
