Abstract
The present invention relates to water-base paint for a die-casting die cavity. The paint of the present invention can thoroughly solve the technical problem of lubrication and demoulding of a die-casting die at a temperature higher than or lower than a normal temperature. The paint is particularly suitable for a majority of units which don't adopt cooling die-casting technology. The paint has the following components (by percentage composition): 36 to 46 percent of mechanical oil, 9 to 12 percent of silicon oil, 1.3 to 6.4 percent of dehydration sorbitol fatty acid ester and the balance of water. The paint reasonably adopts polyacrylamide as additive. The range of a dilution ratio is broader, which is between 1 to 20 and 1 to 80.
Description
The present invention is a kind of die casting die cavity water based paint.
Die casting water base paint is a kind of new coating that rises in the sixties, and it has more advantages such as cooling capacity is strong, surface quality of continuous castings good, environmentally safe compared with oil-based paint except the key property that guarantees all die cast coatings.The lubricant for Russian Patent (54) die-casting die used the most close with the present invention, that is: (54) С М А З К А Д Л Я Ф О Р М Л И Т Ь Я Л О Д Д А В Л Е Н И Е М, certificate number is 963688.The purpose of this patent of invention is to improve the surface smoothness of foundry goods, and its component is emulsifying agent, surfactant and is lubricant to contain the potassium water-repelling agent.And the objective of the invention is to utilize die casting water base paint of the present invention still can guarantee good lubricating release effect, and have surface of good fineness simultaneously in order to solve die casting under the situation of being partial to normal temperature.In order to guarantee that mold in the way that the country that the high-temperature condition bottom knockout has has adopted cooling die, makes it the needs that coating satisfies lubrication.And task of the present invention is to solve the problem of the high temperature demoulding from another angle, by the lubricant of selecting to satisfy the demand, the ignition device for multi-functional liquid fuel coal furnace that makes it to be mixed with has the effect that still can play good lubricating release under the high temperature, and also can satisfy the superperformance of water based paint under the lower situation of mold temperature.It also is the ignition device for multi-functional liquid fuel coal furnace that adopts lubricant and emulsifying agent preparation that the present invention compares with Soviet Union patent of invention 963688, has adopted different lubricants but come from different goals of the invention.
The present invention makes lubricant with the mixed liquor of lightweight or middle machine oil(MMO) and silicone oil.This hybrid lubricant possesses adaptability widely, and this is that compression mod (＜170 ℃) under lower temperature also can satisfy the lubrication to the moving component of die casting because the volatilization point of machinery oil is lower; And the viscosity height of silicone oil, high high-temp stability is good, and volatilization point is also high, still can keep the performance of its normal temperature in the time of 300 ℃.Mould is in the time of 280～300 ℃, after moisture content in the coating and the volatilization of part machinery oil, the volatile quantity of silicone oil is few, and viscosity changes also less, still can stick to mold cavity surface well and form oil film, thus guaranteed compression mod when high temperature coating the lubricating release effect that should have.Certainly separately use silicone oil to make the die cast coating that lubricant forms and also can have high temperature demoulding effect, but if use silicone oil separately is that cost is higher on the one hand, the more prior film that is the silicone oil particulate forms at die surface when mold temperature lower (180～200 ℃) just is difficult for evenly scattering, and easily pile up protruding, this just has bad influence to cast(ing) surface fineness, and can not play the lubricating release effect effectively.The present invention adopts machinery oil and silicone oil mixed liquor to do lubricant, and compression mod is in 180～280 ℃ of temperature ranges, no matter pressing mold still can both guarantee that at low temperature coating has good lubricating release effect at high temperature.Machinery oil plays a major role during low temperature, and silicone oil plays a major role during high temperature, and in the two effect of auxiliary film forming each other again of different temperatures.
Lubricant machinery oil and silicone oil are two kinds of materials of different nature, with carrier water be inconsistent under normal conditions, make emulsion so will add surfactant (emulsifying agent), just a kind of ignition device for multi-functional liquid fuel coal furnace of this emulsion.By emulsification test from numerous emulsifying agents, select the most effective, cost is low, the rational emulsifying agent of consumption also is a difficult point of the present invention.Emulsifying agent of the present invention is: sorbitan fatty ester type and two kinds of emulsifying agents of polyoxyethylene sorbitan fatty acid ester type, just sapn (Span) type and tween (Tween) type with regard to trade name.These two kinds of emulsifying agents all belong to nonionic surface active agent, and emulsion is subjected to the influence of extraneous ion to want littler comparatively speaking like this.Become compound emulsifying agent by these two kinds of emulsifier combination, the mixing film strength that adopts the made emulsion of compound film strength during far above the single emulsifying agent of independent use, this is because compound can further reduce surface tension, thereby increase the boundary and adsorbance, form more compact arranged adsorption layer, thereby increase interfacial film intensity.The stability of its emulsion is obviously better than the school fruit of single emulsifying agent.
The prescription of being made up of foregoing two kinds of lubricants and two kinds of emulsifying agents of the present invention is (weight ratio):
Gently, middle machine oil(MMO) 36～46%
Silicone oil 9～12%
Sorbitan fatty ester 1.3～6.4%
Polyoxyethylene sorbitan fatty acid ester 2.1～6.4%
Water surplus
In coating, added additive for making the present invention possess anti-corrosive properties and enlarging stability boundary,, made emulsion, prevented the emulsion layering or analyse oil at normal temperature and high temperatures comprising stabilizer alcohol and triethanolamine.Increase preservative sodium benzoate, thereby guarantee emulsion not mouldy fouling under the summer temperature condition with higher, play the effect of killing mould and suppressing its growth.Increase the thickener polyacrylamide, it is a kind of macromolecular compound, can be adsorbed on the formation of liquid bead surface and have certain thickness polymer protective film, plays the effect of stable emulsion, has also increased the viscosity of coating simultaneously; But because macromolecular compound has flocculation simultaneously, so addition must be moderate; Polyacrylamide also has the effect of auxiliary film forming in addition, and promptly coating still can effectively form film under the situation of highly diluted ratio.The prescription of the additive that is increased is (weight ratio):
Ethanol 0.1～0.4%
Triethanolamine 0.2～0.6%
Sodium Benzoate 0.2～0.6%
Polyacrylamide 1.5～2%
The present invention is an additive owing to having adopted the macromolecular compound polyacrylamide, thereby has increased the thinner ratio scope of coating.In casting technique for the material of different model, the foundry goods of differing complexity, different mould temperature will adopt different thinner ratios when using coating.It is to want the coating of different model that other water based paint adopts different thinner ratios, and the dilutable scope of coating that is exactly same model is generally about 20, and promptly thinner ratio is 1: 20～1: 40.And the dilutable scope of the present invention can reach about 60, and promptly thinner ratio is 1: 20～1: 80, so use the present invention to adopt different thinner ratios very easily with Mo Wen according to different foundry goods, this just can reduce the cost of coating significantly.The present invention makes it to have possessed simultaneously the lubricating release performance under low temperature and high-temperature condition owing to reasonably selected lubricant for use.Normal mold temperature is 230～240 ℃, compression mod is increase in temperature in use, coating just must all meet the demands when low, high temperature, regional temperature height different in a mould is also different, can not just can not play lubrication at the higher position of mold temperature by resistant to elevated temperatures water based paint as if a kind of, the demoulding is difficult for, foundry goods is pulled thereby cause.The present invention just adopts the factory of cooling press mold technology to solve under the compression mod high temperature for great majority also have condition, adopts other ignition device for multi-functional liquid fuel coal furnace and the demoulding that causes is difficult for the difficult problem that foundry goods is pulled.Because of adopting the present invention to have identical effect, so use the present invention also can simplify casting technique with increase cooling press mold technology.
