Abstract
The invention provides an injection molding material for signal lamp housing shells. The injection molding material comprises glass filled polyethylene terephthalate which contains 0.5wt% of mica and 10-15wt% of mixed pigment of red vanadate and ferricyanide; the material is good in light transmittance and stable in coloring.
Description
Technical field
The present invention has about a kind of injectable plastic material, particularly as the injectable plastic material of vapour rear signal lamp shell.
Background technology
Along with the change of technical development and people's idea, in automobile component, there are many non-metallic components.Be wherein plastics part as the leading material of non-metallic component, it is easy to process, easy for installation, uses lightly, therefore more and more obtains the favor of automobile industry, and using plastics part is its inevitable requirement of development of automobile from now on.
Injection moulding is a kind of technique, by using molding-system to become molded articles by material produce by molded.Molding process (for example injection molding process) is used to produce different molded articles.
As typical nonmetal parts part in automobile, be an important moulding through the vapour rear signal lamp of injection moulding.
Owing to belonging to signal lamp as car rear, after processing, should there is good transparence, to guarantee the maximum illumination of light.Meanwhile, it need to provide dyeing processing in the time of injection moulding, due to the chemical reaction between injectable plastic material and fuel, can cause and with the passing of time produce fuzzy phenomenon, when impact illumination, also affects sending of signal, generation degeneration and the blooming of for example red shell.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of signal lamp shell injectable plastic material, it comprises: glass-filled type polyethylene terephthalate, and contain in described polyethylene terephthalate: the mica that mass percent is 0.5%, and the mass percent red vanadate that is 10 ~ 15% and the hybrid pigment of ferricyanate.
In the present invention, adopt glass-filled type polyethylene terephthalate, it has good transparence, simultaneously, the absorption of mica is the object of the non-crystal structure to adjustment injectable plastic material also, and raising light transmission, and inorganic salt pigment can be resisted the generation of high temperature and later stage oxidation degeneration, keep the stable of color.
Embodiment
The invention provides the injectable plastic material of signal lamp shell, this material makes to have good service performance, particularly transparence through the shell of injection moulding, to guarantee the maximum illumination of light, should guarantee the thermostability of color and the characteristic of anti-oxidant degeneration simultaneously.
The invention provides a kind of signal lamp shell injectable plastic material for this reason, it comprises: glass-filled type polyethylene terephthalate, and contain in described polyethylene terephthalate: the mica that mass percent is 0.5%, and the mass percent red vanadate that is 10 ~ 15% and the hybrid pigment of ferricyanate.
The present invention adopts glass-filled type polyethylene terephthalate (PET), and PET material is because having crystal and non-crystal structure, and in the time that non-crystal structure strengthens, its light transmission is better, but mechanical property declines.Adopt the PET of glass-filled type, it has good transparence, and mechanical property for this reason.
Meanwhile, the absorption of mica is the object of the non-crystal structure to adjustment injectable plastic material also, and improves light transmission, and inorganic salt pigment can be resisted the generation of high temperature and later stage oxidation degeneration, keeps stablizing of color.
As the preferred embodiments of the present invention, the mica wafer that described mica is titanium dioxide-coated.Itself also there is the effect of pigment.Therefore in the time that same PET uses, color and mechanical property are protected simultaneously.
As preferred scheme, the diameter of described mica wafer is 10 ~ 20 microns.
As another embodiment of the present invention, described material also comprises styrene-acrylonitrile copolymer (SA).Vinylbenzene composition make SA hard, transparent and be easy to processing; Vinyl cyanide composition makes SA have chemical stability and thermostability.SA has the ability of very strong carry load, anti-chemical reaction ability, thermal deformation resistant characteristic and geometrical stability.
As the improvement of the present embodiment, in described styrene-acrylonitrile copolymer, contain mass percent and be 2% red fragrant methane series pigment.Adopt organic dye to improve the new energy of printing opacity.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claim provide, with and dependent claims.
