摘要：

综合实验不仅可以使学生更好地掌握实验技能，还可以让学生了解化学研究的基本过程，培养学生独立的科研能力，更好地激发学生进行科学研究的兴趣，因而越来越受到高校教育工作者的重视。本文设计了一个综合实验教学方案：通过对粉煤灰进行表面改性，使改性后的粉煤灰替代轻钙、炭黑作橡胶填料，实验数据表明，表面改性后的粉煤灰对橡胶具有较好的补强作用。同时用改性粉煤灰作橡胶填料可降低工业成本，具有重大的经济效益和社会效益。

关键词: 综合实验, 粉煤灰, 表面改性, 橡胶填料

Abstract:

Comprehensive experiments can improve not only the students' experimental skills, but also their understanding of the basic process of chemical research. Furthermore, comprehensive experiments can cultivate students' independent scientific research ability, which is paid more and more attention by college educators. In this paper, a comprehensive experiment is designed:the surface modification of fly ash is carried out and the modified fly ash is replaced with light calcium and carbon black as rubber filler. The experimental data show that the surface-modified fly ash has a better reinforcement effect on rubber. At the same time, using modified fly ash as rubber filler can reduce industrial cost and have great economic and social benefits.

Key words: Comprehensive experiment, Fly ash, Surface modification, Rubber filler
