Description

Ultra-thin magnesium alloy electronic part die casting parting agent special
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:
