Abstract
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 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
LED light fixture is energy-conservation 90% compared with ordinary incandescent lamp, compared with fluorescent energy-saving streetlamp energy-saving 50%.But because LED chip is luminous, mainly concentrate on LED chip surface, from LED lens, this part light sending is more concentrated, therefore it is very dazzling for interior lighting, easily because of its human consumer's ocular pain, affected to a certain extent the popularization of LED light fixture, therefore 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 lamps of weathering resistance.Polycarbonate resin (PC) is directly used in LED light fixture lampshade can not solve glare problem.
Prior art has been made some explorations from lampshade by forming process two aspects of material and lampshade for the glare problem of LED light fixture.The emerging product of bright dipping (Chinese patent: 200680020541) material flowability problem when solving the injection molded of light diffusing sheet (thickness 1 ~ 3mm) of 20 inches of TV purposes backlight used, has adopted the mode of aromatic series PC/ light diffusing agent/vinylbenzene and alkylmethacrylate polymer blend to obtain high workability light diffusion PC material.This molding mode can not moulding LED light fixture cast lampshade.Chinese patent CN101880450.A discloses a kind of LED lamp tube material and preparation method thereof.This patent is only to provide a kind of material, does not relate to the method for using this material to make fluorescent tube.
At present, lighting decoration controlled field is generally to add in single screw extrusion machine such as aforementioned photodiffusion material, by extrusion die, is fixed to fluorescent tube goods.The method has the shortcoming that material and tubulation process are carried out respectively.
Chinese patent CN101943329.A is by coat phosphor powder layer above LED chip, and the method that header arranges reflection cup makes anti-glare LED fluorescent tube.Chinese patent CN101761804.A, by utilize technique to form frosting at fluorescent tube upper housing outside surface, is used magic square to obtain not dazzling LED fluorescent tube interior being lining with.Above working method has course of processing complexity, 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 is to provide 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 polycarbonate composite material, is comprised of 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 described polycarbonate resin is: 1.2kg, 300 ℃, 4 ~ 12g/10min.
In above-mentioned polycarbonate composite material, described thermo-stabilizer is the mixture of the 1:1 in mass ratio of antioxidant 1010 and irgasfos 168.
In above-mentioned polycarbonate composite material, the photostabilizer trade mark that described photostabilizer is BASF AG is 770.
In above-mentioned polycarbonate composite material, fluorescent whitening agent OB-1 that described processing aid is BASF AG.
In above-mentioned polycarbonate composite material, described light diffusing agent is 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:
First each component is added and in mixing machine, mix 10-20 minute, then it is added to twin screw extruder from main spout, each component arrives after cross-head after plasticizing, shearing dispersion and homogenizing, by extrusion die extrusion moulding, be fluorescent tube, then after air cooling and diameter-setting equipment, obtain extrusion grade light diffusion LED fluorescent tube.
Compared with prior art, the present invention has following beneficial effect:
The present invention is by using twin screw extruder, bring into play its than single screw extrusion machine to material cutting dispersive ability and the strong innate advantage of homogenizing ability, each component of light diffusing polycarbonate matrix material is directly added to twin screw extruder, by being arranged on the mould at twin-screw extrusion machine head place sizing, air cooling obtains one-time formed LED light fixture fluorescent tube.Than first making light diffusion PC matrix material with forcing machine at present, then this material is added to the method that makes LED light fixture use fluorescent tube in the single screw extrusion machine that mainly plays plastifying material effect, the method of disposal molding of the present invention has more the economical and 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 time processing expense; The one-time formed method of the present invention has stain easy to control, without will carry out stain control when processing light spreads PC matrix material separately as prior art, needs again to carry out stain control while being again shaped to tubing in this matrix material is added to forcing machine.
