Abstract

The invention discloses a precise casting medium temperature modulated wax and a preparation method thereof. The precise casting medium temperature modulated wax is prepared from the following raw materials in part by mass: 44-46 parts of microcrystalline wax, 2.5-3.5 parts of lignite wax, 34-36 parts of rosin resin, 3.5-4.5 parts of ethylene-vinyl acetate copolymer, and 12-14 parts of pure monomer resin. The modulated wax disclosed by the invention is applied to the precise casting industry, and has the advantages of being strong in stability, high in strength, hard to deform, low in gray level, capable of reducing the pollution to the metal casting, easy to demold and easy to melt along with a wax pattern while demolding so as to flow out of a molding shell, and capable of effectively improving the production efficiency in the precise casting process.

Description

technical field [0001] The invention relates to the precision casting industry, in particular to a precision casting mid-temperature modulated wax used in the precision casting industry and a preparation method 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 of the investment casting enterprises in my country is the modulated wax made by investment casting enterprises - stearic acid medium temperature mold material. The quality of the mold material is low, the cost is high, and it seriously affects the improvement of the casting quality. Little competition in the international market. However, many investment casting enterprises in my country hope to produce castings for expor...
