The invention discloses a preparation process method of a non-metallic mineral casting, and relates to the technical field of application of non-metallic mineral castings. According to the invention, the design is reasonable, the operation temperature is controlled at 20-30 DEG C, and the conditions that the epoxy resin component A in the curing agent is easy to crystallize in an environment below 20 DEG C and is not suitable for uniform stirring in the stirring process are avoided, so that the curing agent is mixed more uniformly, and the quality of the nonmetallic mineral casting is improved; the weighing time of the epoxy resin component A and the epoxy resin component B in the curing agent is 10 min before casting operation, the situation that the epoxy resin component B in the curing agent is an amine curing agent and can react with ammonium salt in air, and consequently bubbles are prone to occurring in the mixture stirring process is avoided, and therefore the generation of the bubbles is reduced, the density of the non-metallic mineral casting is improved, and the service life of the non-metallic mineral casting is prolonged. The strength is enhanced; meanwhile, the temperature of a drying room is increased, the forming time is shortened, and the preparation efficiency of the nonmetallic mineral casting is greatly improved.
本发明公开了一种非金属矿物铸件制备工艺方法，涉及非金属矿物铸件应用技术领域。本发明设计合理，将操作温度控制在20℃～30℃，避免固化剂中的环氧树脂A组分在20℃以下的环境容易结晶，在搅拌过程中不宜搅匀的情况，使固化剂的混合更加均匀，提高了非金属矿物铸件的质量；固化剂中环氧树脂A组分、环氧树脂B组分的称取时间，在浇铸作业前10min内，避免固化剂中的环氧树脂B组分为胺类固化剂，会与空气中的反应生成铵盐，导致拌合物在搅拌过程中易出现气泡的情况，从而减少气泡的产生，提高了非金属矿物铸件密度，增强了其强度；同时提高了烘房温度，使其成型时间缩短，大大提高了非金属矿物铸件制备的效率。
