The invention relates to the technical field of mineral castings, in particular to an epoxy-resin-based mineral casting which comprises the following raw materials in percentage by mass: 25-35% of filler, 50-60% of aggregate, 5-10% of admixture, 5-8% of epoxy resin and 1-2% of curing agent. In the invention, the large-particle aggregate can be used as a skeleton support to improve the mechanical property of the mineral casting; after the large-particle aggregate is mixed, pores are formed among particles, the small-particle-size filler is filled in the pores, and meanwhile, the epoxy resin is cured and can permeate into the pores, so that the combination of the large-particle aggregate, the filler and the epoxy resin is firmer; 50-60% of aggregate is used as a main component, 25-30% of filler is added, and the mineral casting is formed through bonding of the epoxy resin curing agent; and under the proportion, the mineral casting is high in compressive strength, tensile strength and bending strength, not prone to cracking and breaking in the using process and wide in application range.
本发明涉及矿物铸件技术领域，具体而言，涉及一种环氧树脂基矿物铸件，其按质量分数计包括以下原料：填料25‑35％，骨料50‑60％，掺合料5‑10％，环氧树脂5‑8％和固化剂1‑2％。在本发明中，大颗粒骨料可作为骨架支撑，以提高矿物铸件力学性能，大颗粒骨料混合后，其颗粒之间具有孔隙，小粒径的填料填充在孔隙中，同时环氧树脂固化可渗透到孔隙中，使得大颗粒骨料、填料、环氧树脂的结合更加牢固。以50‑60％的骨料为主要成分，加入25‑30％的填料，通过环氧树脂固化剂的粘合形成矿物铸件，在该配比下，矿物铸件的抗压强度、抗拉强度以及抗弯强度高，在使用过程中不容易开裂和断裂，使用范围广。
