Description
Technical field
The present invention relates to a kind of ultra-thin magnesium alloy electronic part die casting parting agent special.
Background technology
Ultralight, extra small, the ultrathin IT electronic products such as the mobile phone released in the market, laptop computer, its outward appearance housing
All cast using resin material.Resin material density is small, shaping is simple, but there is also drawback:First, waste and old housing can not divide again
Solution utilizes, and seriously pollutes environment;Second, with the further development of IT product ultrathin, casing rigidity and rigidity are difficult to meet to want
Ask.On the other hand, it is proposed the substitute of resin-case in the industry in recent years -- magnesium alloy shell.Because magnesium alloy shell has density
Small, outstanding advantages of intensity is high, thermal diffusivity and shielding are good, recyclable recycling, so getting most of the attention and favoring once listing.
But due to indispensable auxiliary agent in forming technique -- the research and development of releasing agent relatively lag behind, so domestic magnesium alloy at present
Shell cast factory is still generally stripped using common releasing agent, so as to seriously constrain the further of magnesium alloy shell ultrathin technology
Development.Also there is releasing agent of some producers in development & production magnesium alloy electronic part die casting the country at present, but due to, it is backward in technique
It is poor in the prevalence of release property etc. reason(Adsorbance < 0.5mg/100cm2), poor lubricity(Coefficient of friction > 0.25), molten soup
Poor fluidity(100cm2Steel plate extension area < 28.2cm2)The problems such as, cause magnesium alloy electronic part demoulding difficulty, be molded slow, table
Face blacks, is uneven.
The content of the invention
It is an object of the invention to provide a kind of ultra-thin magnesium conjunction with fine lubrication function, demolding performace, heat resistance
Golden soft copy die casting parting agent special.
The present invention technical solution be:
A kind of ultra-thin magnesium alloy electronic part die casting parting agent special, it is characterized in that:It is made up of the composition of following weight percents:
Octamethylcy-clotetrasiloxane emulsion 25-35%
Silicone modified styrene-acrylate emulsion 15-25%
Paraffin base mineral oil 1-5%
Palm oil 1-3%
Neopelex 3-6%
Sodium sulfate of polyethenoxy ether of fatty alcohol 1-3%
Sodium phosphate 2-5%

Benzothiazolinone 0.5%
Pure water surplus.
Advantage of the present invention:
1. formula is from the polymerizable aqueous pitch dispersant of excellent thermal insulation performance(Substitute the synthetic ester that tradition uses)Compatibility, carry
The demolding performace of high product(Through experiment, under 400 DEG C of high temperature heating conditions, SPCC steel plates are sprayed on after being stripped 60 times of dilution agent
On, its adsorbance >=1.0mg/cm2;TGA thermogravimetric tests, active constituent content >=50%).
2. formula is compounded from high viscosity mineral oil and vegetable oil(Substitute organic pulvis that tradition uses), improve product
Greasy property(Through experiment, under 150 DEG C of hot conditions, product coefficient of friction≤0.158).
3. formula, which is selected, has Long carbon chain(C8-C10)With the modification silicon emulsion with benzene ring structure(Substitute what tradition used
Dimethyl-silicon emulsion), lift the ductility of product(Through experiment, 100cm2Steel plate extension area can lift 40.3cm2).
Using without using poisonous and harmful substances such as heavy metal, aromatic hydrocarbon(It is high, right from function admirable, biodegradability
The friendly alternative material of human and environment), product acute oral toxicity LD50 >=5000mg/kg, acute inhalation toxicity LC50 >=
5000mg/m3, No respiratory mucosal irritation, safety and sanitation quality height.
With reference to embodiment, the invention will be further described.
