Abstract

The article presents the adhesive properties of a new binder based on epoxy resin with the addition of waste granite powder. The binder was modified with granite powder in amounts ranging from 10% to 60% in relation to the weight of the resin. Moreover, a coating was made without the addition of the granite powder in order to compare the obtained results. Previously obtained pull-off test results were also analyzed. The obtained results confirmed that the optimal material solution includes 10% or 20% of granite powder by weight. Additionally, chemical and microstructural analysis was also performed for both the reference sample and the sample modified with 20% of granite powder. The article also presents an explanation of the reasons for such an improvement of pull-off strength, which is based on careful analysis of the adhesive properties of the epoxy resin bonding agent modified with waste granite powder. Moreover, it explains how granite powder particles penetrate into the near-surface layer of the substrate, examines the porosity of the near-surface layer of the substrate using microstructural analysis, and presents the effect of adding waste granite powder to the epoxy resin bonding agent on the chemical properties of the near-surface layer of the substrate.

废花岗岩粉改性环氧树脂胶粘剂的粘接性能

本文介绍了一种以环氧树脂为基材，添加废花岗岩粉的新型粘结剂的粘结性能。粘合剂用花岗岩粉进行改性，其量根据树脂的重量从10%到60%不等。此外，还制作了不添加花岗岩粉的涂层，以比较所得结果。还分析了先前获得的拉脱测试结果。实验结果表明，花岗岩粉的最佳配比为10%或20%。此外，还对参考样品和添加20%花岗岩粉的样品进行了化学和微观结构分析。通过对废花岗石粉改性环氧树脂胶粘剂的粘接性能的分析，阐述了拉拔强度提高的原因。阐述了花岗岩粉颗粒如何渗透到基材近表层，通过微观结构分析考察了基材近表层的孔隙度，并介绍了在环氧树脂粘结剂中加入废花岗岩粉对基材近表层化学性能的影响。
