Description
Technical field
The present invention relates to a kind of releasing agents, and in particular to a kind of metal release agent.
Background technology
Casting is one of fundamental technology of modem devices process industry, is into meeting necessarily required liquid by Metal Melting
And pour into casting mold, the technical process of the casting of predetermined shape, size and performance is obtained after cooled and solidified is handled.Casting is de-
Mould is a step important in casting technique, is directly related to the quality of cast article, and therefore, releasing agent is demoulded as casting
In most important auxiliary material, performance directly influences the quality of cast article.
Releasing agent is an a kind of interface coating for being used in two body surfaces for being easy to adhesion each other, it can make object table
Face be easy to be detached from, it is smooth and clean.In casting process, the effect of releasing agent be prevent from pouring casting after in-mold molding with mould
Tool, which occurs to glue, to be sticked, and causes to mold or casting damage causes production that can not carry out, cause damages.After casting releasing agent,
Product can be made smoothly to be removed from the molds, ensure the intact qualification of product.
At present, metal release agent in the market is mainly water based mold release agent and oil base releasing agent, oil base releasing agent need with
Dichloromethane, petroleum ether, 120# gasoline equal solvent tune use after converting, and opposite water based mold release agent cost is higher for it, it is hidden to there is safety
Suffer from and not environmentally, so the use of more releasing agent being mainly in the market water based mold release agent.However, water based mold release agent is heat-resisting
Property it is poor, performance is also unstable, under high temperature environment water based mold release agent easily occur carbonization loses stripping result, after demoulding
Product and die surface have drawing trace, need a large amount of manpower and time to remove residue, equipment can not continuous production.
Invention content
It is an object of the invention to overcome above-mentioned technical deficiency, a kind of metal release agent and preparation method thereof is proposed, solve
The technical issues of metal release agent demolding performace is poor in the prior art, poor heat resistance and performance are unstable.
To reach above-mentioned technical purpose, technical scheme of the present invention provides a kind of metal release agent, and the releasing agent includes
The raw material of following parts by weight：70~90 parts of fluorographite, 5~25 parts of graphite, 1~3 part of dispersant, fluorinated surfactant 0.1
~0.5 part.
Compared with prior art, beneficial effects of the present invention include：The metal release agent that the technical program provides is powder
Releasing agent is 70~90 parts of fluorographite by parts by weight, 5~25 parts of graphite, 1~3 part of dispersant and 0.1~
0.5 part of fluorinated surfactant composition, main component is fluorographite and graphite, and the fusing point of both substances is all higher, tool
There are enough heat resistances, and both substances have excellent greasy property, during as releasing agent, can be formed in die surface
One layer of fine and close lubricating film can improve the mobility of metal in a mold, and casting is made smoothly to be detached from from mold, keep casting
Part surface it is smooth；The dispersant of 1~3 part of addition simultaneously, on the one hand can make fluorographite, graphite and fluorine surface-active
Agent disperses more uniform, the effective agglomeration for solving powder release agent, and on the other hand can improve metal casting can
Release property；On the one hand the fluorinated surfactant of 0.1~0.5 part of addition simultaneously can reduce the viscosity of metal casting, on the other hand
It can ensure that fluorographite and graphite are effectively sprawled in die surface；These types of substance is used cooperatively according to certain proportioning,
The heat resistance of releasing agent can be not only improved, and keeps good chemical stability, it can also be ensured that releasing agent has excellent
Lubricity makes casting be smoothly detached from from mold, is not remained on mold；And the releasing agent that the technical program provides may be used also
The phenomenon that effectively to solve the agglomeration of powder release agent and unstable quality, convenient for storing and transporting for a long time.
