The invention discloses a polycarbonate composite material and a method for making an extrusion grade light diffusion light emitting diode (LED) lamp tube. The polycarbonate composite material consists of the following components in percentage by weight: 89 to 99.79 percent of polycarbonate resin, 0.01 to 8 percent of light dispersant, 0.1 to 1 percent of heat stabilizer, 0 to 1 percent of light stabilizer, and 0.1 to 1 percent of processing aid. The making method comprises the following steps of: adding the components into a mixer, mixing the components for 10 to 20 minutes, adding the mixed components into a double-screw extruder from a main feeding hole, plasticizing, shearing, dispersing and homogenizing the components, extruding the components through a head mold after the components reach the head of the extruder to form a lamp tube, and obtaining the extrusion grade light diffusion LED lamp tube through an air cooling and sizing device. According to the making method, one-time forming is realized, one-time processing expense is reduced, and dark spots are easily controlled.
Description
Technical field
The present invention relates to the polycarbonate composite material technical field, specifically, relate to the making method of a kind of polycarbonate composite material and extrusion grade light diffusion LED fluorescent tube.
Background technology
The LED light fixture is energy-conservation 90% than ordinary incandescent lamp, than energy-saving fluorescent lamp energy-conservation 50%.But mainly concentrate on the led chip surface because of led chip is luminous; See from the LED lens; This part light that is sent is more concentrated, so that it is used for interior lighting is very dazzling, is prone to because of its human consumer's ocular pain; Influenced the popularization of LED light fixture to a certain extent, so eliminate the difficult problem that dazzle becomes LED light fixture indoor application.Polycarbonate as the application of LED light fixture lampshade brought into play just that its transmittance is higher, good weatherability, toughness advantages of higher.PMMA is because of poor, the crisp application that is not suitable for indoor LED light fixture of weathering resistance.Polycarbonate resin (PC) directly is used for LED light fixture lampshade can not solve glare problem.
Prior art has been made some explorations from lampshade with forming process two aspects of material and lampshade to the glare problem of LED light fixture.(Chinese patent: 200680020541) (the material flowability problem has adopted the mode of aromatic series PC/ light diffusing agent/vinylbenzene and alkylmethacrylate polymer blend to obtain high workability light diffusion PC material to the emerging product of bright dipping during the injection molded of thickness 1 ~ 3mm) for the light diffusing sheet that solves the used purposes backlight of 20 inches TV.This molding mode can not be used the cast lampshade by moulding LED light fixture.Chinese patent CN101880450.A discloses a kind of LED lamp tube material and preparation method thereof.This patent only provides a kind of material, does not relate to the method for using this material to process fluorescent tube.
At present, the lighting decoration controlled field generally is with adding in the single screw extrusion machine such as the aforementioned lights diffusion material, being fixed to the fluorescent tube goods through extrusion die.This method has the shortcoming that material and tubulation process are carried out respectively.
Chinese patent CN101943329.A is through coating phosphor powder layer above led chip, the method that header is provided with reflection cup makes anti-glare LED fluorescent tube.Chinese patent CN101761804.A forms frosting through utilize technology at fluorescent tube upper housing outside surface, on liner, uses magic square to obtain not dazzling LED fluorescent tube.Above working method has course of processing complicacy, shortcoming that system cost is high.
Summary of the invention
The object of the present invention is to provide a kind of polycarbonate composite material.
Another object of the present invention provides a kind of making method of extrusion grade light diffusion LED fluorescent tube.
To achieve these goals, the present invention adopts following technical scheme:
A kind of polycarbonate composite material, form by following compositions in weight percentage:
Polycarbonate resin 89 ~ 99.79%
Light diffusing agent 0.01 ~ 8%
Thermo-stabilizer 0.1 ~ 1%
Photostabilizer 0 ~ 1%
Processing aid 0.1 ~ 1%.
In above-mentioned polycarbonate composite material, the melting index of said polycarbonate resin is: 1.2kg, 300 ℃, 4 ~ 12g/10min.
In above-mentioned polycarbonate composite material, described thermo-stabilizer is the mixture by mass ratio 1:1 of antioxidant 1010 and oxidation inhibitor 168.
In above-mentioned polycarbonate composite material, said photostabilizer is that the photostabilizer trade mark of BASF AG is 770.
In above-mentioned polycarbonate composite material, described processing aid is the white dyes OB-1 of BASF AG.
In above-mentioned polycarbonate composite material, described light diffusing agent is the organosilicon microballoon, and the trade mark is the MH-10FD of Korea S KELON company.
Utilize above-mentioned polycarbonate composite material to prepare the making method of extrusion grade light diffusion LED fluorescent tube, comprise the steps:
Earlier each component is added in the mixing machine and mixed 10-20 minute; Then it is added twin screw extruder from main spout; After arriving cross-head after each component process plasticizing, shearing dispersion and the homogenizing; Through the extrusion die extrusion moulding is fluorescent tube, again through obtaining extrusion grade light diffusion LED fluorescent tube behind air cooling and the diameter-setting equipment.
Compared with prior art, the present invention has following beneficial effect:
The present invention is through using twin screw extruder; Bring into play it and material is sheared dispersive ability and the strong innate advantage of homogenizing ability than single screw extrusion machine; Each component of light diffusing polycarbonate matrix material is directly added twin screw extruder, and mould through being arranged on twin screw extruder head place and sizing, air cooling obtain one-time formed LED light fixture and use fluorescent tube.Make light diffusion PC matrix material than present elder generation with forcing machine; Then this material is added in the single screw extrusion machine that mainly plays the plastifying material effect and make the method for LED light fixture with fluorescent tube; The method of disposal molding of the present invention has more economical and the manageable advantage of quality; Be in particular in that one-step moulding method of the present invention has reduced the course of processing, has reduced the time processing expense; The one-time formed method of the present invention has stain easy to control, need not as prior art, when processing light spreads the PC matrix material separately, will carry out stain control, need carry out stain control when in this matrix material adding forcing machine, being shaped to tubing once more again.
