A rapid mass production of the high performance holographic recording articles including the process and composition are described. To prepare a high performance holographic recording article based on two-component urethane matrix system, for example, polyols and all the additives must be virtually free of moisture contents. Deaeration must be carried out, once isocyanate and polyols including catalysts and all other ingredients are mixed together, to eliminate all entrapped air that is introduced into the mixture during mixing. The deaeration takes time, and the urethane reaction must not be allowed to take place until all air bubbles are evacuated from the isocyanate-polyols mixture. The rapid mass production of this invention overcomes such process limitations and results in a high-volume production of the high performance holographic recording articles.
本文介绍了一种快速批量生产高性能全息记录制品的方法,包括工艺和成分。例如,要制备基于双组分聚
氨酯基质系统的高性能全息记录制品,多元醇和所有添加剂必须几乎不含
水分。
异氰酸酯和多元醇(包括催化剂)以及所有其他成分混合在一起后,必须进行脱气,以消除在混合过程中进入混合物的所有夹带空气。脱气需要时间,在
异氰酸酯-多元醇混合物中的气泡全部排出之前,不得进行聚
氨酯反应。本发明的快速批量生产克服了这些工艺限制,可大批量生产高性能全息记录产品。
