Aluminum alloy forging release agent

Abstract

The invention discloses an aluminum alloy forging release agent. The release agent comprises, by weight, 2-5% of an isobutene and maleic anhydride copolymer, 1-2.5% of sodium hydroxide, 2-5% of polyvinyl alcohol, 0.1-1% of polyacrylamide, 0.5-2% of sodium carboxymethyl cellulose, 3-5% of sodium polyphosphate, 2-5% of borax, 1-2% of sodium benzoate, 0.5-1% of siloxane ketone, and the balance of deionized water. Under the action of siloxane ketone and polyvinyl alcohol, the isobutene and maleic anhydride copolymer, polyacrylamide, sodium carboxymethyl cellulose, sodium polyphosphate, borax and sodium benzoate form a surface layer with good lubricity and demolding property at high temperature, and the surface layer is non-stick to a mold, so that the production efficiency of demolding operation is improved; most importantly, under high-temperature forging, due to the water retention characteristic, particles in the components are not prone to drying to generate dust, the problem that a traditional forging release agent seriously pollutes the environment is solved, and due to the fact that graphite is not contained, stains, pits and corrosion cannot be generated on forgings, and cleaning after forging is more convenient.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy forging technology, and in particular relates to a release agent for aluminum alloy forging. Background technique [0002] Since the 21st century, with the continuous improvement of science and technology, the metal processing industry has developed rapidly, and then promoted the progress of a large number of forging equipment and forging technology, and at the same time provided a strong guarantee for the manufacture of forged products in our country. At present, my country's forged products can not only meet its own production needs, but also expand to the international market at an annual growth rate of about 20%. However, with the rapid development of the forging industry, we have also discovered an important problem that restricts the development of the industry, that is, environmental protection. [0003] Because the forging production process will generate a lot of heat, it will hav...

AI Technical Summary

Problems solved by technology

[0004] During the forging production process, the residues of the graphite series release agent after use are not easy to remove, and are easy to embed on the surface of the forging, which will cause stains, pits and corrosion, and bring a lot of inconvenience to the cleaning after forging

Secondly, during the forging process, due to the high temperature, a large amount of graphite dust will float in the air of the factory, causing serious dust pollution and causing irreversible damage to the health of workers

At the same time, a large amount of graphite dust will flow with the air due to the magnetic effect, and thus adhere to the electrical components, causing consequences such as power distribution short circuit and motor burnout, which will bring immeasurable losses to the enterprise
