A photocurable sheet-form material which comprises (a) a polymerizable unsaturated monomer, (b) a polymer which is either polymethyl methacrylate or a high-molecular polymer consisting mainly methyl methacrylate units and which is compatible or swollen with the polymer (a), (c) a photocuring agent, and (d) a fibrous reinforcement. It is excellent in productivity, handleability, and photocurability. This photocurable sheet-form material is usable for producing a layered molding and forming a backup layer (reinforcing layers) of a molded article, and is a useful material as a replacement protective material for pipes, covering material, lining material, fixing material, or the like.
一种光固化片状材料,由以下部分组成:(a) 可聚合的不饱和单体;(b)
聚甲基丙烯酸甲酯或主要由
甲基丙烯酸甲酯单元组成的高分子聚合物,且与聚合物 (a) 相容或膨胀;(c) 光固化剂;(d) 纤维状增强材料。它在生产率、操作性和光固化性方面都非常出色。这种光固化片状材料可用于生产分层模塑产品和形成模塑产品的后备层(加强层),是一种有用的材料,可用作管道的替代保护材料、覆盖材料、衬里材料、固定材料或类似材料。
