Abstract

The invention discloses a production formula of a releasing agent used for casting and a preparation method thereof. The releasing agent is composed of hydroxypropyl methacrylate, crylic acid, butyl acrylate, styrene, ammonium persulphate, an emulsifying agent OP, deionized water, calcium stearate, calcium carbonate, talc powder, titanium pigment, sodium polyacrylate, alcohol ester 12 and silane.During production, a synthesis emulsion is prepared with an emulsion polymerization method; the synthesis emulsion is put into a high-speed dispersion machine; and then, the sodium polyacrylate, the talc powder, the titanium pigment, the calcium carbonate, the calcium stearate, the alcohol ester 12 and the silane are added into the dispersion machine to obtain the releasing agent used for casting. The releasing agent has the advantages of good releasing effect and low production cost, and does not corrode castings, and the castings can not generate mildew, corrosion and the like even if beingstored for more than a half year.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and relates to a production formula of a release agent for casting and a production method thereof. Background technique

[0002] At present, the casting mold release agents used in the market are all relatively expensive. The mold release agents are acidic or alkaline, and have a certain corrosion effect on the surface of the casting. After a period of storage, mold spots or slight corrosion will occur on the surface phenomenon and other defects. Contents of the invention

[0003] The purpose of the present invention is to provide a production formula and a preparation method of a neutral release agent with good demoulding effect, low production cost and no corrosion effect on castings.

[0004] In order to achieve the above object, a mold release agent for casting of the present invention consists of hydroxypropyl methacrylate, acrylic acid, butyl acrylate, styrene, ammonium persu...
