Description
本発明は、枕木や建築材等を初めとする各種の用途に使用される繊維強化樹脂成形品に関する。 The present invention relates to a fiber-reinforced resin molded product used for various applications including sleepers and building materials.

難燃性ウレタン樹脂組成物は反応して硬化するため、その粘度は時間の経過と共に変化する。そこで難燃性ウレタン樹脂組成物を使用する前は、難燃性ウレタン樹脂組成物を二以上に分割して、難燃性ウレタン樹脂組成物が反応して硬化することを防止しておく。そして難燃性ウレタン樹脂組成物を使用する際に、二以上に分割しておいた難燃性ウレタン樹脂組成物を一つにまとめることにより、難燃性ウレタン樹脂組成物が得られる。 Since the flame retardant urethane resin composition reacts and cures, its viscosity changes over time. Therefore, before using the flame retardant urethane resin composition, the flame retardant urethane resin composition is divided into two or more to prevent the flame retardant urethane resin composition from reacting and curing. And when using a flame-retardant urethane resin composition, a flame-retardant urethane resin composition is obtained by putting together the flame-retardant urethane resin composition divided | segmented into two or more.
なお難燃性ウレタン樹脂組成物を二以上に分割するときは、二以上に分割された難燃性ウレタン樹脂組成物のそれぞれの成分単独は硬化が始まらず、難燃性ウレタン樹脂組成物のそれぞれの成分を混合した後に硬化反応が始まるようにそれぞれの成分を分割すればよい。 In addition, when dividing the flame retardant urethane resin composition into two or more, each component of the flame retardant urethane resin composition divided into two or more does not start to cure, and each of the flame retardant urethane resin composition Each component may be divided so that the curing reaction starts after the components are mixed.
難燃性ウレタン樹脂組成物の製造方法は特に限定されないが、例えば、難燃性ウレタン樹脂組成物の各成分を混合する方法、難燃性ウレタン樹脂組成物を有機溶剤に懸濁させたり、加温して溶融させたりして塗料状とする方法、溶剤に分散してスラリーを調製する等の方法、また難燃性ウレタン樹脂組成物に含まれる反応硬化性樹脂成分に25℃の温度において固体である成分が含まれる場合には、難燃性ウレタン樹脂組成物を加熱下に溶融させる等の方法により難燃性ウレタン樹脂組成物を得ることができる。 The method for producing the flame retardant urethane resin composition is not particularly limited. For example, the method of mixing the components of the flame retardant urethane resin composition, the flame retardant urethane resin composition suspended in an organic solvent, A method of heating and melting to form a paint, a method of preparing a slurry by dispersing in a solvent, etc., and a reaction curable resin component contained in a flame retardant urethane resin composition at a temperature of 25 ° C. When the component which is is contained, a flame-retardant urethane resin composition can be obtained by methods, such as melting a flame-retardant urethane resin composition under heating.

また、ウレタン樹脂の主剤と硬化剤とをそれぞれ別々に充填材等と共に混練しておき、注入直前にスタティックミキサー、ダイナミックミキサー等で混練して得ることもできる。 Alternatively, the main component of urethane resin and the curing agent may be separately kneaded together with a filler or the like and kneaded with a static mixer, a dynamic mixer or the like immediately before injection.
さらに触媒を除く難燃性ウレタン樹脂組成物の成分と、触媒とを注入直前に同様に混練して得ることもできる。以上説明した方法により難燃性ウレタン樹脂組成物を得ることができる。 Further, the components of the flame retardant urethane resin composition excluding the catalyst and the catalyst can be kneaded in the same manner immediately before injection. A flame-retardant urethane resin composition can be obtained by the method described above.
