| 摘 要： | 分析了济宁地区粉煤灰的外观形貌和化学组成，并用于聚烯烃胶粘带防腐层补强性能研究，着重研究了粉煤灰添加量对聚烯烃胶粘带防腐层力学性能的影响。实验结果表明：粉煤灰中的化学成分以 SiO2、Al2O3、 Fe2O3为主，三者总质量分数高达88.04%，CaO的质量分数为12.40%，此粉煤灰属于碱性灰；粉煤灰中有少量非晶态玻璃体的存在，主要晶体矿物是石英、莫来石和赤铁矿；添加粉煤灰后，聚烯烃胶粘带防腐层的力学性能得到提升；当粉煤灰添加量为15份时，试验品的力学性能最优，拉伸强度91.93 N/cm、断裂伸长率536.67%、剥离强度33.43 N/cm；煤粉灰是一种优良的填充剂，可以代替碳酸钙用于聚烯烃胶粘带防腐层的生产。此研究不仅能提高粉煤灰的利用率和附加值，改善聚烯烃胶粘带防腐层的各项性能，还能为工业粉煤灰在橡胶补强方面的产业化应用提供理论依据。

| Abstract: | This paper analyzes the chemical composition and structural characteristics of the fly ash in the Jining area, and how it could improve the performance of the anticorrosive coating of polyolefin adhesive tapes with a focus on the influence of the fly ash content on their mechanical properties. The experimental results show that the fly ash is mainly composed of SiO2, Al2O3, and Fe2O3, the total mass fraction of which is approximately 88.04%. The mass fraction of CaO is 12.40%. The fly ash is an alkaline ash with a small amount of amorphous vitreous bodies and certain crystal minerals such as quartz, mullite, and hematite in it. Subsequent to adding fly ash, the mechanical properties of the anticorrosive coating of polyolefin adhesive tapes are improved. Subsequent to adding 15 batches of fly ash, the mechanical properties of the test sample are optimal with its tensile strength being 91.93 N/cm. Furthermore, the elongation at fracture is 536.67%, and the peel strength is 33.43 N/cm. Fly ash is an excellent filler that can replace calcium carbonate in the production of the anticorrosive coating of polyolefin adhesive tapes. The study can not only improve the utilization and added value of fly ash, improving the properties of the anticorrosive coating of polyolefin adhesive tapes, but it can also provide a theoretical basis for industrial applications of industrial fly ash in rubber reinforcement. |
