Problems solved by technology

But there are some deficiencies in the mechanical parts prepared by these materials. The existing mineral castings for making mechanical parts are generally composed of aggregates, fillers and cementing materials. The cementing material used is a mixture of epoxy resin and curing agent. The difference in surface tension of the materials is small, and the cement cannot fully wet the aggregate. After mixing with the aggregate and filling materials, the viscosity of the whole system is very high and it is difficult to stir evenly. The epoxy resin generates gas during the curing process, and the compacting pr

Abstract

The invention provides a mechanical component mineral casting and a mechanical component preparation method using the same. The mineral casting comprises an aggregate accounting for 60-80% of a total weight, a cementitious material accounting for 15-20% of a total weight and the rest of a filling material. The aggregate is granite particle with a grain size of 0.1mm-20mm; the cementitious material is a mixture of epoxy resin, hardener and thinner; and the filling material is ceramic powder, hollow glass bead, calcium carbonate powder or alumina powder. According to the invention, surface tension of the cementitious material is reduced substantially through addition of thinner in the cementitious material and ultrasonic mixing activation; during a batch mixing process, the cementitious material fully moistens the aggregate, so that components of the mineral casting are uniformly distributed after mixing, and each part in the mineral mechanical component is solidified evenly; the prepared mechanical component has uniform structural organization, consistent performance, high mechanical property and good precision and stability.

Description

technical field [0001] The invention relates to a mineral casting for making mechanical parts and a method for preparing mechanical parts by using the mineral casting, and belongs to the technical field of mineral castings for mechanical parts. Background technique [0002] The publicly reported materials show that the research and use of resin-mineral composite materials in the field of mechanical manufacturing began in the 1970s, and the application of artificial granite to mechanical components was first carried out in Switzerland and Germany. Precision and ultra-precision machining represent the cutting-edge technology level in a country's manufacturing field, and have become an important means for countries in the world to compete in technology, market and even arms. This requires machining and measuring equipment to have higher precision, dynamic stability and Thermal stability, resin-mineral composites can meet this requirement. The main raw material for the producti...
