Abrasion-resistant epoxy mortar with low thermal linear expansion coefficient and preparation method thereof
The invention provides abrasion-resistant epoxy mortar with a low thermal linear expansion coefficient and a preparation method of the abrasion-resistant epoxy mortar, and belongs to the field of building materials, the abrasion-resistant epoxy mortar comprises 100 parts of epoxy resin, 10-25 parts of a curing agent, 400-600 parts of quartz sand, 10-60 parts of a microsphere filler and 10-100 parts of an auxiliary agent; the epoxy resin is prepared from cage type gamma-glycidyl ether oxygen propyl silsesquioxane; the microsphere filler is a carbonized product of epoxy resin microspheres; the thermal expansion performance of the epoxy resin is reduced by compounding the modified filler, the bonding stability of the epoxy mortar as concrete reinforcement is improved, and meanwhile, the thermal expansion performance and the impact wear resistance of the epoxy mortar are further improved by introducing the silicon-containing epoxy monomer into the epoxy matrix.
本发明提供一种低热线性膨胀系数的抗冲磨型环氧砂浆及其制备方法，属于建筑材料领域，所述抗冲磨型环氧砂浆包括：环氧树脂100份、固化剂10‑25份、石英砂400‑600份、微球填料10‑60份和助剂10‑100份；所述环氧树脂包括笼型γ‑缩水甘油醚氧丙基倍半硅氧烷；所述微球填料为环氧树脂微球的碳化产物；本发明通过复配改性填料降低环氧树脂的热膨胀性能，提高环氧砂浆作为混凝土补强的粘结稳定性，同时在环氧基体中引入含硅环氧单体进一步改善其热膨胀性能和耐冲磨性能。
