Demoulding agent

Abstract

The invention discloses a demoulding agent. The demoulding agent is prepared from, by weight, 12%-18% of organic dibasic acid, 7%-16% of sodium hydroxide, 2%-6% of sodium polymethacrylate, 0.2%-0.8% of isodecanol polyoxyethylene ether, 0.1%-0.5% of polyacrylamide, 0.5%-4% of polyisobutylene succinic anhydride, 1%-7% of organic silicon resin, 0.1%-0.2% of defoamer and the balance water, wherein the organic dibasic acid adopts phthalandione or isophthalic acid or hexanedioic acid. The demoulding agent does not contain graphite and has excellent high-temperature adhesion property, lubricating property and cooling property, the demoulding effect is good, the compatibility with water is excellent, removing through water washing is facilitated, an extremely strong protective effect is exerted on a mold, and it can be guaranteed that residues of the mold are less, the surface is bright and smooth, and the service life of the mold is greatly prolonged.

Description

technical field [0001] The invention relates to a mold release agent, in particular to a warm forging and hot forging agent which does not contain graphite, has excellent high-temperature adhesion, lubricity and cooling, excellent miscibility with water, and a strong protective effect on the mould. Water soluble mold release agent. Background technique [0002] The mold release agent is an important auxiliary material in the forging process, which plays an important role in the forging process. The molding condition, smoothness and life of the mold surface are closely related to the mold release agent. [0003] At present, there are certain deficiencies in the release agents used at home and abroad, for example: the ductility and film-forming properties of aluminum powder and copper powder are poor, and it is difficult to form a dense film when the amount of use is small, which affects the release performance. When it is large, it is easy to form accumulation layers, which ...

Problems solved by technology

[0003] At present, there are certain deficiencies in the release agents used at home and abroad, for example: the ductility and film-forming properties of aluminum powder and copper powder are poor, and it is difficult to form a dense film when the amount of use is small, which affects the release performance. When it is large, it is easy to form accumulation layers, which affects the size and precision of castings; molybdenum disulfide has poor demoulding effect, complex composition, and contains organic solvents that are harmful to the environment; Cause short circuit of electrical equipment, and graphite is atomized and scattered around during high-temperature forging, resulting in graphite dust pollution, which seriously damages the health of operators; other release agents also have serious accumulation on the surface of the mold, which is inconvenient Defects such as cleaning need to be scraped manually, which consumes a lot of labor costs
