In particular, the silicone-based pressure-sensitive adhesive composition is often used in combination with a fluororesin or a fluororesin-impregnated glass cloth substrate because of its feature of being easily adhered to various adherends and its high heat resistance. It is awarded in applications that require

ある。[0003] Pressure-sensitive adhesive tapes used for heat-resistant applications are required not to be peeled off by heat. In addition, when the tape is replaced, there is little adhesive residue on the adherend. Characteristics are required. Such a problem of adhesive residue is a property often required in pressure-sensitive adhesive tapes other than heat-resistant applications. In particular, in heat resistant applications,
Exposure to a high temperature promotes deterioration due to heat, so that the problem of adhesive residue is likely to occur, which is a characteristic that is difficult to countermeasure.

体側とに分かれて、結果として糊残りとなる。[0004] Such a problem of adhesive residue is generally caused by the cohesive failure of the adhesive layer of the pressure-sensitive adhesive tape when the pressure-sensitive adhesive tape is peeled from the adherend. For more information,
At the boundary between the adhesive layer of the pressure-sensitive adhesive tape and the adherend when the pressure-sensitive adhesive tape is peeled off from the adherend, the adhesive layer is pulled up by the tape substrate and bonded to the adherend interface. It is stretched with the force of the elastic force to cause elastic deformation. At this time, if the tape base is further pulled up in a state where the tape base is being pulled back by the elastic deformation of the adhesive layer, the adhesive layer is further stretched,
The pullback force is even stronger. Eventually, when the force due to the elastic deformation of the adhesive layer becomes stronger than the force at which the adhesive layer is bonded to the adherend, the bond between the adhesive layer and the adherend is broken, causing interfacial peeling, and the adhesive layer adheres. Peel from body. In this case, if the cohesive force of the adhesive layer is small, the adhesive layer causes cohesive failure before the bond with the adherend is broken, and the adhesive layer is divided into the base material side and the adherend side, resulting in adhesive residue. Becomes

げてしまう不都合がある。Since the problem of adhesive residue is caused by cohesive failure of the adhesive layer, it is considered that the problem can be suppressed to some extent by increasing the cohesive force of the adhesive layer. However, if the cohesive force of the adhesive layer is excessively increased, when the tape is adhered to the adherend, the interface of the adhesive layer flows on the adherend surface due to the effect of wetting, preventing the interface from bonding, and consequently bonding. There is an inconvenience of lowering the power.

な糊残り性を両立させることが困難であった。As described above, silicone-based pressure-sensitive adhesive tapes are often used at high temperatures where heat resistance is required. When the pressure-sensitive adhesive tape is held at a high temperature, the fluidity of the pressure-sensitive adhesive composition forming an adhesive layer increases, and the pressure-sensitive adhesive composition bonds more firmly. , Adhesive residue is more likely to occur. For this reason, it has been difficult for a silicone-based pressure-sensitive adhesive tape to achieve both high adhesive strength and good adhesive residue.

ようなものを見出したものである。The present invention focuses on the fact that the cause of adhesive residue is largely due to the cohesive force of the silicone-based pressure-sensitive adhesive composition forming the adhesive layer in the pressure-sensitive adhesive tape, and the cohesive force is high at high temperatures. It is designed to rise when heated and held below. As a means of increasing the cohesive force at a high temperature, a method has been found which increases the gel fraction at a high temperature.

抑えられる。The silicone-based pressure-sensitive adhesive composition of the present invention contains a crosslinked structure, and is at room temperature (25 ± 2 ° C.,
When the adhesive is applied to an adherend, an appropriate gel fraction (initial gel fraction) of the crosslinked structure gives the interface of the pressure-sensitive adhesive composition an appropriate fluidity. On the other hand, when heated and held at a high temperature, the gel fraction increases and the cohesive force can be increased. Therefore, the silicone-based pressure-sensitive adhesive composition of the present invention has good adhesiveness to an adherend at room temperature, and is held in a state where the gel fraction is increased and the cohesive force is increased at a high temperature. Therefore, when peeling back to normal temperature after exposure to high temperature,
The cohesive force is larger than the bonding force to the adherend, and the generation of adhesive residue can be suppressed.

い。When the silicone-based pressure-sensitive adhesive composition is heated and held at the above-mentioned high temperature, the rising range of the gel fraction is determined by the initial gel fraction at which the crosslinked structure exhibits an appropriate adhesive force to the adherend at room temperature. , But it is 5 to 55% by weight. If the increase in the gel fraction is too small, a sufficient effect of increasing the cohesive force will not be obtained, and glue residue will be generated.
It is preferable that the increasing range of the gel fraction be 10% by weight or more. On the other hand, if the increase in the gel fraction is too large, the adhesive force will be extremely reduced, causing the tape to float at the ends and to peel off the tape. The increase range of the gel fraction is 35% by weight or less,
Further, the content is preferably 25% by weight or less. In particular, the gel fraction is desirably increased in the range of 10 to 25% by weight.

していても良い。Since the crosslinking reaction of the peroxide-based crosslinking agent is a radical reaction, the crosslinking reaction usually proceeds at a high temperature of 150 ° C. to 220 ° C. On the other hand, since the crosslinking reaction between the vinyl group-containing organopolysiloxane and the siloxane-based crosslinking agent is an addition reaction, the reaction usually proceeds at a low temperature of 80C to 150C. As described above, the crosslinking reaction of the peroxide-based crosslinking agent and the crosslinking reaction of the siloxane-based crosslinking agent have different crosslinking reaction temperatures. Utilizing the reaction temperature difference, the composition is cross-linked with a siloxane-based cross-linking agent at a relatively low temperature of 150 ° C. or less, and the composition is formed into a crosslinked structure having the initial gel fraction. The resulting silicone-based pressure-sensitive adhesive composition has a desired initial gel fraction and good adhesion, and is maintained at a high temperature after being adhered to an adherend by a peroxide-based crosslinking agent. Further, the crosslinking reaction can be advanced to increase the gel fraction. In the state of the silicone pressure-sensitive adhesive composition, the peroxide crosslinking agent may remain as a radical.

段は問われない。In the silicone-based pressure-sensitive adhesive composition of the present invention, if the initial gel fraction and the gel fraction when heated and held at the above-mentioned high temperature can be adjusted to the above-mentioned ranges, types of the crosslinking agent and the like are limited. Instead, a peroxide-based crosslinking agent can be used alone as the crosslinking agent. When the peroxide-based crosslinking agent is used alone, the silicone-based pressure-sensitive composition is adjusted by adjusting the amount of the peroxide-based crosslinking agent, the crosslinking reaction temperature, and the like, when the composition is formed into a crosslinked structure. The same effect as described above can be obtained by allowing the peroxide-based crosslinking agent or its radical to remain in the adhesive composition. In this case, the organopolysiloxane used as the silicone rubber may or may not have a vinyl group. When a vinyl group is present, a crosslinking reaction is also caused on the vinyl group by the peroxide crosslinking agent. In addition, the silicone-based pressure-sensitive adhesive composition of the present invention can leave the cross-linking agent by any means as long as the initial gel fraction and the gel fraction when placed at the high temperature can be adjusted to the above ranges.
