Abstract

The invention discloses precision casting concocted wax. The concocted wax is prepared from, by weight, 38-42 parts of microcrystalline wax, 18-25 parts of paraffin, 10-12 parts of candelilla wax, 20-24 parts of polystyrene, 16-25 parts of stearic acid, 25-32 parts of ethylene-ethyl acetate copolymer, 9-12 parts of 1,3-oxaazacyclohexane, 10-15 parts of octadecanoic acid, 14-22 parts of calcium stearate, 8-10 parts of sodium dodecyl benzene sulfonate, 12-20 parts of rosin resin, 20-32 parts of ethylene-vinyl acetate copolymer, 18-30 parts of pure monomer resin and 5-6 parts of compatilizer. Compared with the prior art, the precision casting concocted wax has the advantages that a preparing method is simple and reasonable in process, the softening point of the prepared casting concocted wax is within the ideal range so that the concocted wax can be easy to demold in the casting process, and production efficiency is high; the prepared casting concocted wax is low in linear shrinking percentage and subsidence rate, the size stability of the product is high, and a casting is high in surface smoothness and high in quality.

Description

technical field [0001] The invention relates to the technical field of casting wax, in particular to a precision casting modulated wax and a treatment process thereof. Background technique [0002] With the development of society, precision castings have been widely used in aviation, weapons and other industrial sectors, especially electronics, petroleum, chemical, transportation, light industry, textile, pharmaceutical, medical equipment, pump and valve components. [0003] The mold material used by most investment casting enterprises in my country is the modulated wax mold material made by investment casting enterprises. The quality of the mold material is low, the cost is high, and it seriously affects the improvement of the quality of the castings. The castings produced are competitive in the international market. small. However, many investment casting enterprises in my country hope to produce castings for export. If castings are to be exported, the quality of castings...
