Abstract
The present invention discloses an environmentally friendly dispersed aqueous aluminium alloy release agent without aluminum silicon powder. The release agent comprises a film-forming powder, an anti-sintering powder, an anti-rust agent, a surfactant and water. The product provided by the invention has excellent anti-sintering performance, demoulding performance and heat resistance.
Description
Technical field
The present invention relates to a kind of environment-friendly type without silica flour agent disperse aqueous aluminum alloy mould release agent.
Background technology
Aluminum alloy mould release agent is the auxiliary agent that aluminum alloy die-casting technological must use.In recent years, along with the improving constantly of complicated, large-scale die-casting machine clamp force of the maximization of precision die and die cast product volume, structure, and the requirement such as die quality, service life, die cast product aft-loaded airfoil, more and more higher to the performance quality requirements of aluminum alloy mould release agent.Simultaneously along with the brute force of nation-building resource-conserving and environment-friendly society advances, user also pays close attention to its usage economy and the safety and sanitation of product more.Aluminum alloy mould release agent commercially available at present all uses the emulsion-type releasing agent of silicate-containing oil substantially.The emulsion releasing agent appearance time of silicate-containing oil is long, technology of preparing, technical maturity, anti-oxidant, good corrosion resistance, but simultaneously also there are some great drawbacks: one be silicate-containing oil emulsion major part is organic matter formation, its heat resistance bad (thermolytic rate >=30%), stripping result general (when epithelium gage distortion, film partial fracture and membrane workpiece and mould bite generation the phenomenon such as to pull and happen occasionally), anti-sintering property poor (the at high temperature easily carbonization of the organic matter in emulsion causes surface of the work to occur blackspot); Two is follow-up applications (silicone oil volatilized under high temperature is adsorbed on electronics aluminium casting surface, easily causes short circuit, disk read-write bad) that silicate-containing oil emulsion affects workpiece; Three is generally all contain the poisonous and harmful substances such as heavy metal in formula, and safety and sanitation are of poor quality.
Summary of the invention
The object of the present invention is to provide a kind ofly has the environment-friendly type of excellent anti-sintering property, demolding performace and heat resistance without silica flour agent disperse aqueous aluminum alloy mould release agent.
Technical solution of the present invention is:
A kind of environment-friendly type, without silica flour agent disperse aqueous aluminum alloy mould release agent, is characterized in that: be grouped into by the one-tenth of following weight percents:
Film forming pulvis ... 15 ~ 20%
Anti-sintering pulvis ... 4 ~ 10%
Antirust agent ... 4 ~ 15%
Surfactant ... 5 ~ 10%
Water ... surplus.
Film forming pulvis is aluminium magensium silicate and/or sodium aluminate.
Anti-sintering pulvis is magnesium silicate, magnesia, one or more in aluminium oxide.
Antirust agent is one or more in bay diacid, decanedioic acid, n-nonanoic acid, petroleum sodium sulfonate.
Surfactant is one or more in 400 oxirane hydroxyl alcohol, alkyglycosides, dodecyl polyglyceryl ether.
Advantage of the present invention:
1. formula is selected the inorganic anti-sintering pulvis of high-quality (substitute commercially available prod use silicone oil) and is not easily organized 5 by pyrolytic, the inorganic film forming pulvis (substituting the macromolecule organic that commercially available prod uses) with special molecular structure, play the novel surfactant of excellent dispersion effect, composite rear in the solution dispersed.The composite lubricating film that die surface is formed is sprayed on after dilution, there is excellent anti-sintering property (cast(ing) surface Non-carbonized and blackspot during 600 DEG C of high temperature, weight reduces < 20%), demolding performace (when 300 DEG C of high temperature, 100 multiplying powers dilution demoulding resistance≤6.8kg), heat resistance (when 600 DEG C thermolytic rate≤20%), not only overcome the above-mentioned drawback that silicate-containing oil emulsion release agents exists preferably, but also the particular/special requirement of dissimilar, different purposes and size, complicated aluminium alloy castings can be met.
2., because organic powder is cheap, production cost 50% can be reduced under same dilution ratio condition, show its usage economy especially.
3. formula does not use the poisonous and harmful substance such as heavy metal, aromatic hydrocarbon (select biodegradability high, to human body and environmentally friendly alternative raw material), product biological half lethal dose LD50>=5000mg/kg, half lethal concentration LC50>=5000mg/m
3, respiratory mucosa stimulates≤1 grade.
Below in conjunction with embodiment, the invention will be further described.
