Surface-modified mineral casting and preparation process thereof
The invention belongs to the technical field of mineral casting manufacturing, and particularly relates to a surface-modified mineral casting and a preparation process thereof. The raw materials comprise the following components in parts by weight: 50-60 parts of coarse aggregate, 20-28 parts of fine aggregate, 1.5-3 parts of reinforced fibers, 10-20 parts of epoxy resin, 1-3 parts of epoxy resincolor masterbatch, 1-3 parts of dextrin, 2-6 parts of sodium carboxymethyl cellulose, 3-8 parts of zirconium powder, 3-6 parts of fly ash, 2-4 parts of vermiculite, 0.4-1.5 parts of an amine curing agent and 0.2-0.6 part of polyimide. The mineral casting obtained by the invention is integrally formed, according to the preparation method, the operation of secondary surface modification is omitted,in one-time forming, the mineral casting capable of being integrally formed and the preparation process are found out by selecting and adjusting the raw material ratio, the requirement of the castingfor the mechanical property in the using process is further met, and the using performance of the casting is further improved.
本发明属于矿物铸件制造的技术领域，具体涉及一种具有表面修饰的矿物铸件及制备工艺。其原料包括按重量份计算的下述组分：粗骨料50‑60份，细骨料20‑28份，增强纤维1.5‑3份，环氧树脂10‑20份，环氧树脂色母料1‑3份，糊精1‑3份，羧甲基纤维素钠2‑6份，锆粉3‑8份，粉煤灰3‑6份，蛭石2‑4份，胺类固化剂0.4‑1.5份，聚酰亚胺0.2‑0.6份。本发明得到的矿物铸件一体化成型，省去二次表面修饰的操作，在一次成型中，通过对原料配比进行选择和调整，寻找到了一种能够一体成型的矿物铸件和制备工艺，也进一部满足了铸件在使用过程中对于力学性能的要求，进一步提供铸件的使用性能。
