The invention discloses a preparation formula of a non-metallic mineral casting, and relates to the technical field of application of non-metallic mineral castings. The design is reasonable, the formula for preparing the non-metallic mineral casting comprises 7.0-8.0% of an epoxy resin component A, 1.68-1.92% of an epoxy resin component B, 7.0-8.0% of fly ash, 35.0-45.0% of quartz sand and 37.0-47.0% of gravel, adopted aggregate grading is continuous grading, a mixture is not prone to segregation, workability and fluidity are improved, the mixing amount of the fly ash is increased to 7-8% from 3-3.5%, and the mixing amount of the fly ash is increased to 7-8% from 3-3.5%. The ratio of the epoxy resin component A to the epoxy resin component B is 25: 6, so that the internal structure is denser, the compressive strength, the breaking strength and the elastic modulus are increased, the compressive strength is increased to 170 MPa, the breaking strength is increased to 35 MPa, and the elastic modulus is increased to 40 GPa.
本发明公开了一种非金属矿物铸件制备配方，涉及非金属矿物铸件应用技术领域。本发明设计合理，该非金属矿物铸件制备的配方包括：环氧树脂A组分7.0～8.0％、环氧树脂B组分1.68～1.92％、粉煤灰7.0～8.0％、石英砂35.0～45.0％、碎石37.0～47.0％，采用的骨料级配为连续级配，拌合物不宜产生离析，提高了和易性和流动性，粉煤灰掺量由3～3.5％提高至7～8％，能够有效的增加了拌合物的流动性，环氧树脂A组分与环氧树脂B组分的比例为25:6，内部结构更加密实，增加了抗压强度、抗折强度和弹性模量，且抗压强度提升至170MPa,抗折强度提升至35MPa，弹性模量提升至40GPa。
