Definitions
- the present invention relates to a release agent and a release sheet.
- sheet used for a release sheet is used as a concept including a film.
- the release film has a release layer on at least one of the substrates, and is widely used as a material for protecting an adhesive surface or an adhesive surface.
- the release agent forming the release layer is roughly classified into a silicone release agent and a non-silicone release agent.
- Silicone release agents have excellent mold release properties, but in the field of electronic and electrical equipment, failures (corrosion, contact troubles, etc.) due to siloxane-based gas generated in trace amounts have become a problem.
- the non-silicone-based release agent a release agent to reduce the surface energy by halogen compound such as fluoride, polyvinyl force Rubameto (P VA and C 1 8 H 3 7 with NC_ ⁇ a long chain alkyl group-containing polymer release agent comprising the reaction product), polyether Chirenimin and C 1 8 H 3 7 release agent comprising a reaction product of NCO, Pas one Furuo port comprises a copolymer mainly composed of Al Kirubiniru release agent, polyethylene A release agent composed of a resin composition has been proposed.
- Non-silicone release agents have no problem of siloxane gas generation, do not require special catalysts, heat treatment, or other operations. Also have the advantage of being long. However, in general, non-silicone release agents require a larger release force than silicone release agents, or they have poor heat resistance and increase their release force when stored in a state of being bonded to an adhesive under heating. There is a problem of doing. Furthermore, non-silicone release agents have inherent problems depending on the material system used, as described below.
- mold release agents whose surface energy has been reduced by halogen compounds such as fluorides do not meet the current era of the need for degassing to reduce the environmental load in waste treatment.
- Release agents composed of copolymers containing perfluoroalkylalkylvinyl as the main component have excellent release properties, but are generally insoluble in organic solvents and only soluble in special and expensive solvents such as FR thinner. Applications are severely restricted.
- a release agent composed of a polyethylene resin composition includes a release agent containing a low-density polyethylene resin as a main component (for example, Japanese Patent Publication No. 51-205 and Japanese Patent Publication No. Japanese Patent Application Laid-Open No. 2000-258, and a release agent containing a high-density polyethylene-based resin as a main component (for example, Japanese Patent Application Laid-Open Nos. 2000-230396 and 2004-200)
- the release agent containing low-density polyethylene resin as a main component requires a large peeling force, and when used as a pressure-sensitive adhesive layer protective film, adheres when peeled.
- a release agent containing a high-density polyethylene resin as a main component has problems in that it has poor adhesion to a substrate when a polar polymer is used as the substrate, and has a large peeling force. Disclosure of the invention
- the present invention has been made in view of the above circumstances, and has as its object not to contain a silicone-based generated gas component, to have good mold release properties for various pressure-sensitive adhesives, and to have a small variation in peeling force. Further, it is an object of the present invention to provide a release agent and a release sheet capable of maintaining a low peeling force even after being stuck to an adhesive and placed under heating.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that low-density olefin-based elastomers and high-density ethylene- ⁇ -olefin polymers are mainly used. It has been found that the above object can be easily achieved by a mold release agent, and the present invention has been completed.
- the first gist of the present invention is to provide a component (A) having an density of 0.855 gZc c or more and less than 0.868 gZc c, and an olefin-based elastomer having a density of 0.885 gZc c or less, and a component (B): a density of 868 g (more than 0. A release agent containing an ethylene- ⁇ -olefin copolymer of 970 gZc c or less as a main component, wherein the difference between the average density of the component ( ⁇ ) and the average density of the component ( ⁇ ) is 0.005.
- component (A) is a copolymer of at least one selected from the group consisting of propylene, butene, and hexene with ethylene, and the components (A) and Z or the component (B) are functionalized.
- a second gist of the present invention resides in a release sheet having a release layer comprising the above-mentioned release agent on at least one surface of a substrate.
- the release layer is composed of a release agent obtained by a cross-linking reaction between a reactive compound capable of reacting with a functional group of the component (A) or the component (B).
- Figure 1 is an explanatory diagram of how to draw a baseline for the endothermic peak obtained in the DSC measurement.
- the component (A) used in the present invention is an olefin-based elastomer having a density of 0.855 gZcc or more and less than 0.868 gZcc. If the density of the component (A) is too low, the release force of the obtained release agent becomes large, and sufficient release properties cannot be obtained. Also, If the density of the component (A) is too high, the release force of the obtained release agent tends to increase depending on the balance with the component (B): ethylene- ⁇ -olefin copolymer to be described later. Good releasability cannot be obtained.
- the component ( ⁇ ) used in the present invention is an ethylene- ⁇ -olefin copolymer having a density of 0.868 g / cc or more and 0.970 gZcc or less. If the density of the component ( ⁇ ) is too low, the heat resistance and the coating film strength of the obtained release agent become insufficient. If the density of component ( ⁇ ) is too large,
- the density of a polymer depends on crystallinity.
- the density of the crystallized part of the polymer is high.
- the crystallinity of the polymer can be evaluated by the size of the endothermic peak of a differential scanning calorimeter (DSC) in the following manner.
- Adjustment of the measuring device is performed as follows. That is, two empty aluminum pans of approximately the same mass are prepared, each of which is placed on two sample holders, measured under the same conditions as in the actual case, and the measurement equipment is set so that the baseline becomes a straight line. Make adjustments.
- the sample is prepared as follows. That is, a sample is sandwiched between Teflon sheets and formed into a 250-m-thick film by a compression molding machine heated to 200 ° C. Then, it is cooled and solidified by a press molding machine kept at 25 ° C, the Teflon sheet is peeled off, and left at 25 ° C for 1 day for DSC measurement. By such an operation, a sample having a constant thermal history after polymerization can be obtained.
- FIG. 1 is an explanatory diagram of how to draw a baseline for the endothermic peak obtained by DSC measurement.
- (A) is the case where the start point and end point of the endothermic peak are on the same base, and the baseline is a straight line. In this case, draw a linear baseline connecting the above start point and end point, find the peak area, and use it as the endothermic amount.
- (B) is the case where the start point and end point of the endothermic peak do not exist on the same base, and the straight line extrapolated in the peak direction from the start point side intersects with the straight line extrapolated in the peak direction from the end point. is there. In this case, draw a curved base line where the line on the start point side and the line on the end point side can be overlapped to the maximum, determine the peak area, and use it as the heat absorption.
- the start point and end point of the endothermic peak do not exist on the same base, and the straight line extrapolated in the peak direction from the start point side does not intersect with the straight line extrapolated in the peak direction from the end point. Is the case. In this case, draw a linear baseline connecting the above-mentioned start point and end point, find the peak area, and use it as the endothermic amount. When the start point of the endothermic peak is 0 ° C or less and the end point exceeds 0 ° C, the amount of heat absorbed is the amount expressed from 0 ° C to the end point. Cut).
- a crystalline polymer exhibiting an endothermic peak of 1 J / g or more in measurement in a temperature range of 0 to 200 ° C. by DSC is used.
- the lower limit of the density of the component (A) (about 0.855 gZc c) is, in particular, that the component (A) is a copolymer of ethylene and at least one selected from the group consisting of propylene, butene and hexene.
- the crystallinity (heat resistance) is determined in consideration of the above, but the lower limit of the density of the component (A) is about 0.860 gZc c from the viewpoint of crystallinity. is there.
- the component (B) is much more crystalline than the component (A).
- the release agent of the present invention containing the components (A) and (B) having crystallinity as described above as a main component increases the cohesive force due to the presence of the cohesive phase based on the crystallized portion, and the heat resistance Also excellent in scratch resistance.
- the endothermic peak of the component (A) in the DSC measurement is preferably 1 to 50 JZg, more preferably 3 to 30 J / g. When the endothermic peak of the component (A) exceeds 30 J / g, the crystallinity is too high and the release agent tends to be hard.
- the endothermic peak of the component (B) in the DSC measurement is preferably 30 to 250 J / g, and more preferably 35 to 200 JZg.
- component (B) If the endothermic peak of component (B) is less than 30 JZg, there is a tendency that a thermally stable release agent cannot be obtained. When the endothermic peak of component (B) exceeds 250 JZg, there is too much difference in relative crystallinity with component (A), and component (B) crystallizes first in the melting and crystallization processes. It tends to separate from component (A), and a release agent with excellent heat resistance cannot be obtained.
- the difference between the average density of component (A) and the average density of component (B) ( ⁇ io) To at least 0.05 g / cc, preferably at least 0.01 g / cc. If the average density difference ( ⁇ ) is too small, the component ( ⁇ ) and the release agent containing the component ( ⁇ ) as a main component cannot maintain the balance between the release property and the heat resistance.
- the blending ratio (weight ratio) of component (): component ( ⁇ ) needs to be 90:10 to 10:90. That is, as described above, the release agent of the present invention increases the heat resistance by using a component having crystallinity, and the component ( ⁇ ): by selecting the density of the component ( ⁇ ) in an appropriate range, Maintains the balance between heat resistance and mold release properties, but further defines the compounding ratio of component ( ⁇ ): component ( ⁇ ) as described above. By doing so, the balance between heat resistance and mold release properties is further improved. That is, when the compounding ratio of the component (A) exceeds 90% by weight, the heat resistance is lowered due to too much low-density component, that is, component (A), which is a low-melting component.
- component (B) If the compounding ratio exceeds 90% by weight, the component (B), which is a high-density component, is too large and becomes hard, causing a problem in terms of cohesion.
- the compounding ratio (weight ratio) of component (A): component (B) is preferably 80:20 to 40:60.
- Such methods can be used to adjust the peeling force of the olefin elastomer, in addition to adjusting the compounding ratio.
- Such methods include (1) a method of appropriately controlling the stereoregularity of the olefinic elastomer and the ethylene- ⁇ -olefin copolymer to adjust the crystallinity and the glass transition temperature,
- the film strength of the release layer will increase, but the peeling force will increase and the flexibility (secondary workability) of the release layer will decrease. .
