Definitions
- the present invention relates to a sealing material. More specifically, seal materials used for seals for cam covers of automobile engines, seals for oil pans, seals for fuel cell refrigerant, wire harness seals for automobiles, seals for HDD power bar gaskets or anti-vibration HDD cover gaskets, etc. About.
- the cam of an automobile engine is generally fitted with a cam pad that covers the engine block to prevent dust from entering from outside and to protect the cam from splashing lubricant inside.
- the seal material for sealing between the engine block and the cam cover is used as a seal material for the cam cover.
- seal materials for cam covers used for this type of application are duro
- cam covers are changing from metal to resin.
- a sufficient sealing performance can be maintained even with a general rubber seal having a large hardness, but in the case of a resin cam cover, the resin is deformed by the seal surface pressure with a general rubber seal, so
- a problem such as a seal leak occurs due to the above.
- the seal for the cam cover is a large product, injection molding is preferable from the viewpoint of production efficiency.However, the general acrylic rubber composition used as a seal material has problems in fluidity, vulcanization rate, etc. Inferior Some problems are seen.
- Silicone potting material is generally soft because it is liquid, and because it is made of silicone rubber, it has the advantage of ensuring appropriate heat resistance, cold resistance, oil resistance, etc., but it is sealed during engine assembly. It requires a process of applying and curing the material, and has the disadvantage that it cannot be easily replaced.
- a rubber seal is an easily replaceable seal material, but a rubber seal is generally hard and requires a higher surface pressure than a potting material to seal.
- Gaskets for fuel cells must be miniaturized for use in automobiles, etc.Because the fuel cell has a multilayer structure as a whole, there is a demand for lighter components, and it is a seal part. Gasket materials are also required to be lighter. In addition, since brittle parts such as carbon plates are used for separators, etc., it is necessary to prevent the brittle parts from rupturing. Also, since the supporting parts are easily deformed by lightening, the gasket material has low resistance. Empowerment is required. Therefore, the gasket material has a low viscosity before hardening and can be molded thinly and uniformly, and it is necessary to have a low hardness and a low reaction force after the curing molding. JP2003 / 012716
- Liquid silicone rubber and low-viscosity fluororubber are used for conventional fuel cell seals.Even though liquid silicone rubber can achieve low viscosity before cross-linking and low hardness after cross-linking, sealing There are problems such as poor shielding properties against gases such as hydrogen and oxygen, and high gas permeability, as well as poor oil resistance and the inability to use refrigerant oil as a coolant.
- Fluorororubber is sufficient in terms of oil resistance and gas barrier properties, but the millable type cannot reduce the viscosity before cross-linking sufficiently, making it difficult to form a thin gasket, and achieving a sufficiently low hardness. Is also difficult. The same applies when a millable acrylic rubber having excellent heat and oil resistance is used. Liquid fluororubber with a low viscosity before cross-linking achieves this purpose of use, but has a very high material cost. Under these circumstances, there is a need for a seal material that has low viscosity before the bridge, low hardness after cross-linking, good gas barrier properties, and oil resistance.
- Silicone rubber has been mainly used as a sealing material for wire harnesses used for electric wiring of automobiles, industrial machines, etc.Since silicone rubber has poor adhesion to wires, There are problems such as poor oil resistance when used in a room. Furthermore, when the hardness is reduced, the mechanical strength of the wire is low, so that it is easy for the wire to be damaged at the time of wire insertion and the sealing performance is poor.
- Gaskets for electronic storage devices are attached to the housing in such a way that a single rubber or urethane foam sheet is sandwiched between metal covers made of stainless steel or aluminum.
- metal covers made of stainless steel or aluminum.
- thermoplastic elastomer made of a styrene-based thermoplastic elastomer (Japanese Patent No. 2,961,068). Since a thermoplastic elastomer does not require a vulcanization step as compared with a rubber material. It is shown that the process can be simplified, and the material can be recycled and cost down because it is a thermoplastic material.
- a gasket made of a styrene-based thermoplastic elastomer is injection-molded in advance in what is called a frame, and then assembled by integrating it between a housing such as an HDD and the lid. Therefore, a third one called a frame is needed.
- thermoplastic elastomers Due to its properties, thermoplastic elastomers generally tend to undergo permanent deformation under high temperature conditions compared to rubber, and therefore, if they are tightened under high temperature conditions for a long period of time, the sealability due to permanent deformation will increase. Insufficient state.

- a radical polymerization method a living polymerization method is more preferable, and an atom transfer radical polymerization method is particularly preferable.
- the radical polymerization reaction is difficult to control because the polymerization rate is high and a termination reaction such as coupling between radicals is likely to occur, but the living radical polymerization method requires a special polymerization system.

It has the feature that the molecular weight can be freely controlled by the charge ratio of the initiator and the initiator.
