manufacture of poroesen harzgegenstandes and mould from poroesem resin.

摘要

The present invention provides a process for obtaining a porous resin molded product containing continuous holes characterised by using as the molding material a mixture which includes epoxy compound having one or more epoxy groups in each molecule; hardener which reacts with and hardens the epoxy compound; at least two types of monionic emulsifier selected from the three types having respective hydrophilic-lipophilic balances of 4-8, 8-17, and 11-15.6; water or aqueous surface active agent; and filler. …??The invention also provides a mold suitable for slip discharge casting and obtained by the above-defined process according to the invention, preferably using a said a molding material which contains 20-50 parts by weight of hardener per 100 parts by weight of epoxy compound, 30 parts by weight or less of emulsifier and 1-20 parts by weight of water or aqueous surface active agent to 100 parts by weight in total of epoxy compound and hardener; and 30-75 weight percent of filler.
