The invention relates to the technical field of epoxy mortar, in particular to modified powder and graded sand epoxy mortar and a preparation method thereof. The modified powder and graded sand epoxymortar is prepared by the following method: S1, preparing modified zinc oxide powder; S2, preparing a mixture of the modified powder and wood fibers; S3, preparing a component A; S4, preparing a component B; and S5, stirring the component A and the component B to obtain the epoxy mortar. Compared with the prior art, the epoxy mortar has the beneficial effects that 1, the modified powder and the wood fibers are used as partial fillers, so that mortar gaps can be reduced, the compressive strength and breaking strength of the epoxy mortar are obviously improved, and the toughness is improved; 2,the epoxy resin consumption is reduced, and the cost can be reduced; and 3, graded sand can significantly improve the mechanical properties and durability of the epoxy mortar.
本发明涉及环氧砂浆的技术领域，尤其是涉及一种改性粉体与级配砂的环氧砂浆及其制备方法。该环氧砂浆由下述方法制备：S1：改性氧化锌粉末的制备；S2：改性粉体与木质纤维混合料的制备；S3:制备组分A；S4:制备组分B；S5:将组分A与组分B搅拌，得到所述环氧砂浆。本发明具有以下有益效果：1.使用改性粉体与木质纤维作为部分填料，可以减小砂浆空隙，环氧砂浆的抗压强度和抗折强度有明显提高、韧性提高。2.环氧树脂使用量减少，可降低成本。3.级配砂可以显著提高环氧砂浆的力学性能和耐久性能。
