Description
本発明は、反応活性に優れ、得られるフェノキシ樹脂が他の成分、特に硬化剤と混合した際の貯蔵安定性に優れるフェノキシ樹脂の製造方法に関する。 The present invention relates to a method for producing a phenoxy resin having excellent reaction activity and excellent storage stability when the obtained phenoxy resin is mixed with other components, particularly a curing agent.
エポキシ樹脂は耐熱性、接着性、耐薬品性、耐水性、機械的強度及び電気特性等に優れていることから、塗料、土木、接着、電気材料用途等の分野で広く使用されている。そして種々の方法で高分子量化することで製膜性が付与される。その高分子量化されたエポキシ樹脂は、フェノキシ樹脂と称される。特にビスフェノールＡ型のフェノキシ樹脂は、主に塗料用ワニスのベース樹脂、フィルム成形用のベース樹脂として使用され、或いはエポキシ樹脂ワニスに添加して流動性の調整や硬化物としたときの靭性改良、接着性改良の目的に使用される。また、リン原子や臭素原子を骨格中に有するものは、エポキシ樹脂組成物や熱可塑性樹脂に配合される難燃剤として使用されている。 Epoxy resins are widely used in fields such as paints, civil engineering, adhesives, and electrical materials because they are excellent in heat resistance, adhesiveness, chemical resistance, water resistance, mechanical strength, and electrical properties. Then, the film-forming property is imparted by increasing the molecular weight by various methods. The high molecular weight epoxy resin is called a phenoxy resin. In particular, bisphenol A type phenoxy resin is mainly used as a base resin for paint varnish, a base resin for film molding, or added to epoxy resin varnish to adjust fluidity and improve toughness when made into a cured product. Used for the purpose of improving adhesiveness. Further, those having a phosphorus atom or a bromine atom in the skeleton are used as a flame retardant to be blended in an epoxy resin composition or a thermoplastic resin.
フェノキシ樹脂の製造方法としては、一般的に、２官能フェノール化合物にアルカリの存在下、エピハロヒドリンを反応させる「一段法」や、２官能エポキシ樹脂と２官能フェノール化合物を触媒の存在下で反応させる「二段法」等が知られている。二段法は一段法に比べて食塩等の副生成物がほとんど生じないため、合成後に精製することが困難なフェノキシ樹脂の製造に適した方法であることが知られている。非特許文献１には二段法によりフェノキシ樹脂を製造する際の触媒として、アンモニウム塩類化合物、アルカリ性化合物類等が一般的に使用されることが記載されている。 As a method for producing a phenoxy resin, generally, a "one-step method" in which a bifunctional phenol compound is reacted with epihalohydrin in the presence of an alkali, or a "one-step method" in which a bifunctional epoxy resin and a bifunctional phenol compound are reacted in the presence of a catalyst is used. The "two-step method" is known. It is known that the two-step method is suitable for producing a phenoxy resin, which is difficult to purify after synthesis because it produces almost no by-products such as salt as compared with the one-step method. Non-Patent Document 1 describes that ammonium salt compounds, alkaline compounds and the like are generally used as catalysts for producing a phenoxy resin by a two-step method.
フェノキシ樹脂を前述したような塗料、土木、接着、電気材料等の分野で用いる場合、主にベース樹脂として使用されるため、エポキシ樹脂や硬化剤を始めとする他材料との混合物として使用することが一般的である。本発明者らの詳細な検討によれば、二段法で製造する際に、上記非特許文献１に記載されているようなアンモニウム塩類化合物、アルカリ性化合物類を触媒として使用したフェノキシ樹脂は、他材料と混合した際の貯蔵安定性が不十分となる場合がある。また、リン系化合物としてトリフェニルホスフィンが触媒として使用されることも非特許文献１に記載されているが、ホスフィン類化合物は二段法の触媒としては活性が不十分であった。 When phenoxy resin is used in the fields of paints, civil engineering, adhesives, electrical materials, etc. as described above, it is mainly used as a base resin, so it should be used as a mixture with other materials such as epoxy resin and curing agent. Is common. According to a detailed study by the present inventors, other phenoxy resins using ammonium salt compounds and alkaline compounds as catalysts as described in Non-Patent Document 1 when produced by the two-step method are available. Storage stability when mixed with the material may be inadequate. It is also described in Non-Patent Document 1 that triphenylphosphine is used as a catalyst as a phosphorus-based compound, but phosphine compounds are insufficiently active as a two-step catalyst.
本発明の課題は、２官能エポキシ樹脂と２官能フェノール化合物とを二段法で反応させる際に、反応が十分に進行し、かつ得られたフェノキシ樹脂が他材料との配合した際の貯蔵安定性に優れるフェノキシ樹脂の製造方法を提供することにある。 The subject of the present invention is that when the bifunctional epoxy resin and the bifunctional phenol compound are reacted by the two-step method, the reaction proceeds sufficiently, and the obtained phenoxy resin is stable in storage when blended with other materials. An object of the present invention is to provide a method for producing a phenoxy resin having excellent properties.
本発明者らは上記課題を解決するために鋭意検討した結果、２官能エポキシ樹脂と２官能フェノール化合物を原料として用いてフェノキシ樹脂を得る際に、特定のホスホニウムボレート化合物の存在下で反応させることにより、上記課題を解決し得ることを見出し、発明の完成に至った。 As a result of diligent studies to solve the above problems, the present inventors have made a reaction in the presence of a specific phosphonium borate compound when obtaining a phenoxy resin using a bifunctional epoxy resin and a bifunctional phenol compound as raw materials. As a result, it was found that the above problems could be solved, and the invention was completed.
