Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of the manufacture of mineral castings, and particularly relates to a mineral casting with surface modification and a preparation process. Background technique [0002] Mineral castings can be used as structural parts of machines to replace traditional cast iron. It is common to use resin as a binder to bond aggregates together. It has excellent mechanical properties, and shock resistance, precision, damping performance, etc. All of them perform well and have been widely used as processing lathes. With the continuous improvement of performance, the application fields are getting wider and wider. [0003] Most of the mineral castings need to be painted on the surface, which not only plays the role of moisture-proof, but also can be given various colors to meet the production needs, and can also reflect the iconic colors of different enterprises, with obvious identification effect. [0004] In the prior art, ...
