Abstract

The invention discloses a micro-emulsive nonferrous metal mold releasing agent as well as a preparation method thereof. The formula of raw materials comprises the following components in parts by weight: 35-42 parts of emulsifying agents, 10-20 parts of modified plant oil and fat, 5-10 parts of auxiliaries and 29-50 parts of deionized water. The preparation method comprises the following steps of: 1) selecting raw materials; 2) preparing emulsifying agents according to proportion, stirring and heating, thereby obtaining a substance A; 3) heating the modified plant oil and fat; 4) adding the substance A into the modified plant oil and fat in step 3), thereby preparing a substance B through a phase conversion emulsifying method; 4) adding deionized water at 80 DEG C-90 DEG C by multiple times, and stirring at high speed, thereby obtaining a substance C; and 5) preparing the auxiliaries into a solution, adding the solution into the substance C at room temperature, stirring, and filtering, thereby obtaining the micro-emulsive nonferrous metal mold releasing agent. According to the micro-emulsive nonferrous metal mold releasing agent disclosed by the invention, synthetic polyethylene wax is taken as a membrane forming substance so as to obtain the nano particle size mold releasing agent, is beneficial to mold filling by metal liquid and reducing of the mold releasing force, and the defects that the domestic mold releasing agent is poor in mold releasing effect, pollutes a container, can block a spraying pipeline easily and the like are overcome.

Description

technical field [0001] The invention relates to a microemulsion nonferrous metal release agent, in particular to a preparation method of a microemulsion nonferrous metal release agent, which belongs to the field of fine chemicals. Background technique [0002] In the development history of the world's automobile industry, the use of die-casting parts in the design and application of various parts is one of the major research topics, which shows that the die-casting industry plays an irreplaceable role in this regard. Therefore, while the automobile industry drives the development of the die-casting industry, it also directly promotes the development of microemulsion metal die-casting release agents. Microemulsion hydraulic casting release agent can be roughly divided into two grades according to the performance and price of the release agent. The first grade is the imported mold release agent brand from Japan, and the representative products are Japanese Sakurai mold releas...
