不饱和树脂-石英砂复合材料的制备及力学性能研究

Preparation and Mechanical Properties Investigation of Unsaturated Polyester Resin/quartz Sand Composite Materials

用两步法合成了高活性不饱和树脂,研究了树脂的反应性能、催化剂与固化剂含量等因素对树脂固化性能的影响。考察了该不饱和树脂的化学结构和浸润性等对不饱和树脂-石英砂复合材料压缩性能的影响。

The unsaturated polyester resin(UPR)with a high reactivity was synthesized via a two-step method.In addition,the effects of the reactivity of UPR and the dosage of catalyst and curing agent on the reactivity of the UPR were investigated.The effects of chemical structure and wettability of the UPR on the compressibility of UPR-quartz sand composites were also investigated.
