Abstract

The invention belongs to the technical field of precision casting and discloses a precision casting wax granular molding material and a preparation method and application of the precision casting waxgranular molding material. The precision casting wax granular molding material comprises components including, by mass percent, 50%-70% of petroleum wax, 0%-10% of animal wax, 10%-15% of mineral wax,0%-15% of vegetable wax, 0%-15% of petroleum resin, 0%-10% of flexibilizer, 0.0%-0.5% of an ultraviolet light absorbent and 0.0%-1% of an antioxygen. The raw material of petroleum wax is stable and easy to obtain, the petroleum wax serves as a raw material, the cost of the printing wax powder material is greatly reduced, meanwhile, the animal wax, the mineral wax, the vegetable wax, the petroleumresin, the flexibilizer and the like are added to improve the tenacity, the strength and the hardness, the molding material is low in viscosity and melting point and good in flowability, and the granular material is convenient to transport and process. By means of a formula without rosin, it is guaranteed that the casting wax can be repeatedly used several times and is good in environment affinity, meanwhile, the process is simple, the working efficiency is improved, the cost is reduced, and wide market prospects and market competitiveness are achieved.

Description

technical field [0001] The invention belongs to the technical field of precision casting, and in particular relates to a precision casting wax particle mold material and a preparation method and application thereof. Background technique [0002] Investment casting is also called investment precision casting, which uses the lost wax method as the casting method, takes the final product as a copy, presses the wax mold material into an accurate casting model, and then coats the refractory material on the wax mold; the slurry is dried and solidified Finally, the mold shell is formed, and then the wax mold in the solidified mold shell is melted by high-temperature steam or hot water demoulding, and the casting wax flows out to obtain a hollow cavity inside; the hollow mold shell is fired at high temperature to remove Other substances inside the mold shell and further strengthen and dry the mold shell; inject the target metal solution that meets the quality requirements into the m...
