Abstract

The invention discloses a precisely cast low-temperature modulated wax and a preparation method thereof. The precisely cast low-temperature modulated wax comprises the following raw materials in parts by weight: 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 an ethylene-vinyl acetate copolymer and 12-14 parts of pure monomer resin. The wax disclosed by the invention is applied to a precision casting industry, has stability, hardly deforms due to high strength and hardly pollutes the metal cast due to low gray scale, is easy to demold, can be melted together with a wax mold to flow out of a shell during demolding; and the production rate can be effectively improved in the precision casting process.

Description

technical field [0001] The invention relates to the precision casting industry, in particular to a precision casting low-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 all industrial sectors such as aviation and weapons, especially electronics, petroleum, chemical industry, transportation, light industry, textile, pharmaceutical, medical equipment, pump and valve components. The molding material used by most of the investment casting factories in my country is the paraffin-stearic acid low-temperature molding material made by the investment casting factory. Its quality is low, cost is high, and seriously affects the improvement of casting quality, and the casting produced is less competitive in the international market. However, many investment casting factories in our country hope to produce castings for export. If ...
