Abstract

The invention discloses a metal pressure casting releasing agent. The releasing agent comprises, by mass percent, 8 to 15% of epoxy soybean oil modified amino silicone oil, 20 to 30% of Tween 80-ricinoleic acid n-hexadecyl ester-oxprenolol glucosiduronide copolymer, 2 to 5% of 1-hexadecanaminium,2-hydroxy-N-(2-hydroxyethyl)-N,N-dimethyl-,chloride, 1 to 4% of aminopropanol ascorbic acid phosphate,2 to 4% of an emulsifying agent, 0.5 to 1.2% of a defoaming agent and the balance water. The invention further discloses a preparing method of the metal pressure casting releasing agent. The metal pressure casting releasing agent has the good lubricating and mold releasing performance under the high temperature environment, stability is good, when a casting after pressure casting is separated froma mold, mold releasing is easy, smoothness on the surface of the casting after mold releasing is high, and the mold protection effect is good.

Description

technical field [0001] The invention relates to the technical field of metal processing aids, in particular to a metal die-casting release agent and a preparation method thereof. Background technique [0002] Metal die casting is one of the special casting processes. It is a process in which molten metal is filled in the mold cavity under high pressure and high speed, and cooled under high pressure to form. It has high production efficiency, short production process, and high casting finish and strength , less machining allowance and other process characteristics, are widely used in automotive, electronics, communications and other industries. The release agent is an indispensable auxiliary material for the production of die-casting products. Its main function is to help the metal die-casting product to be removed from the mold smoothly, and to keep the product intact and post-processable, thereby preventing mold sticking, improving the formability of metal, and improving di...
