Epoxy resin-based mineral casting and preparation method thereof
The invention provides an epoxy resin-based mineral casting and a preparation method thereof. The mineral casting comprises 85-88 parts of aggregate, 7-9 parts of an adhesive, 4-5 parts of a filler and 1 part of an auxiliary agent, the total amount of all the components is 100 parts. The adhesive comprises epoxy resin and a curing agent. The preparation method comprises the following steps: (1) s1, preparing epoxy resin; s2, preparing the curing agent; (2) preparing aggregate particles; (3) sequentially adding a reinforcing agent and a filling material into a stirring device to obtain a mixture A; (4) weighing the s1 and the s2 according to the formula weight to obtain the adhesive; adding an adhesive into the mixture A to obtain a mixture B; (5) compacting the mixture B by high-frequency vibration to obtain a primary product; and (6) heating and curing the primary product, opening a mold and cooling to obtain a finished product. The compressive strength of the mineral casting reaches 160-180 MPa, and the elastic modulus of compression reaches 40-55 GPa; the preparation method is simple, easy to control and suitable for wide popularization and application.
