Abstract

The invention provides a method for extracting lac wax from filter residues generated in bleached lac producing process and the lac wax prepared by the method. The lac wax extraction method of the invention comprises: coarse lac wax is extracted by using inorganic salt solution; the coarse lac wax is dissolved and decolorized by organic solvents; the lac wax is obtained through decompression and distillation. The invention adopts the filter residues generated in the bleached lac producing process as raw materials, with simple technique and convenient operation, the appearance, luster and physiochemical indexes of the refined lac wax conform to the standards of applying in coating agents and other aspects of food, medicine and cosmetics industries, etc., and the yield and the purity quotient are high. The invention not only comprehensively utilizes resources, but also reduces the environmental pollution, and the economic benefit of enterprises is improved.

Description

A method for extracting lac wax and the lac wax extracted by the method technical field The invention relates to a method for refining fatty substances, in particular to a method for refining natural wax. Background technique Shellac wax, also known as shellac wax, is a natural substance secreted by lac insects parasitic on trees such as Dalbergia blunt-leaf, Dalbergia simao, and Juguo fig. Shellac wax is the same as beeswax, insect wax and other insect waxes. It is widely used in various industries at home and abroad. Its physical and chemical properties are similar to carnauba wax and sugarcane wax. It can be used as hard natural wax to replace carnauba wax and carnauba wax. Mengtan wax is used; shellac wax has a high melting point, good electrical insulation performance and wipe brightness, it can be used as insulating wax for electrical equipment, and can also be used for high-grade leather shoe polish, floor wax, belt wax and other polishing wax It is also widely use...
