Abstract

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.

Description

technical field [0001] The invention relates to a formula for mineral castings, in particular to a formula for preparing non-metallic mineral castings, and relates to the technical field of casting applications. Background technique [0002] The product of mineral casting is mineral casting, which is a future-oriented environmentally friendly material. As a structural part of a machine, it can replace traditional cast iron in some applications due to its price and performance advantages. One is called resin mineral casting with resin glue as binder, and the other is called polymer mineral casting with polymer nano powder as penetrating agent. [0003] The aggregate gradation used in the preparation of existing mineral castings is discontinuous gradation. The disadvantages of this discontinuous gradation are that the mixture is easy to segregate, has poor workability and low fluidity. Therefore, a non-metallic mineral casting preparation formula is proposed to address the ab...
