文物保护用水溶性氨基树脂的研制

A study of the water soluble amino resin for Preservation of Cultural relics

以三聚氰胺、多聚甲醛、尿素、甲醇及聚乙二醇为原料，合成了高分子材料－水溶性三聚氰胺甲醛树脂。本文叙述了该树脂的合成工艺和反应原理及在文物保持应用上的可行性，讨论了反应原料的配比、反应温度、体系的PH值及改性剂聚乙二醇的用量对树脂性能的影响。

Proceed from the angle of preservation of cultural relics, polymeric material-the water soluble melamine formaldehyde resin is syntheised by the reaction of melamine paraformaldehyde, urea methanol & PEG. the properties of the resin will meet the basic requirement of preservatiov of cultural relics. The synthelic process of the resin & the reaction principle of the resin are discribed. the relationships between the characteristic of the resin &the M/F of ratio, temperature of reaction' the value of pH, the amount of modifier-PEG are discussed it is feasible for apply resin to preservation of cultural relics.
