Abstract
The invention relates to a method for manufacturing a fluorescent object. The method comprises steps of preparing raw materials and pressing, wherein the raw materials comprises plastic powder and inorganic fluorescent powder, the weight of the inorganic fluorescent power is 5% that of the plastic powder; the plastic powder is fluororesin powder and after extrusion forming, the hole rate is below 30%, the inorganic fluorescent powder is the combination of ZnS:Mn and Y3Al5O12:Ce or (Y, Gd)3Al5O12:Ce, and the weight of Y3Al5O12:Ce or (Y, Gd)3Al5O12:Ce is 0.5% that of the ZnS:Mn.
Description
Technical field
The invention belongs to fluorescent material and manufacture field, specifically refer to a kind of manufacture method of fluorescent object.
Background technology
Past is that the fluorescent object consisting of " matrix material: plastics "+" dispersion: fluorescent powder " can send fluorescence and catoptrical subject, there is technical literature to disclose a kind of fluorescent object,, with 300 ℃ of above temperature, the fluorescence fluorine resin constituent that makes to contain in fluorine resin inorganic phosphor material and form is carried out to sintering processing, can not cause polymer aging yet, in addition also can not impair the proof voltage of fluorine resin, be exposed to excite radiation in time, this fluorescence fluorine resin constituent radiates radiating light; Also having document to disclose a kind of fluorescent object, is that mixed-powder is filled in mould and is pushed, and adjusts after density (hole rate is 30～50%), takes out powder compact from mould, carries out atmospheric pressure sintering on ceramic wafer.
Fluorescent object in existing technology all can not lack heat fused, such heat treatment step that is heating and curing, therefore need to select not can sex change in heat treatment step inorganic fluorescent powder body.In addition,, in fluorescent object, owing to having added for separating of inorganic fluorescent powder body, having made the UA dispersant of inorganic fluorescent powder body, therefore likely because bringing out, dispersant produces fluorescence noise, ageing of plastics.In addition,, due to needs heat treatment step, therefore can increase cost.If there is fluorescence intensity reduction (fading) the such problem that is irradiated by light in common fluorescent material.
Summary of the invention
The object of the invention is to, a kind of technical scheme that does not produce fluorescence noise, can not cause the cheap fluorescent object manufacture method of ageing of plastics is provided.
The present invention is achieved by the following technical solutions:
A manufacture method for fluorescent object, its step comprises:
Preparation raw material, includes preparing plastic powder and inorganic fluorescent powder body; The weight of described inorganic fluorescent powder body be plastics powder weight 5%; Described plastics powder is fluororesin powder, and extrusion modling hole rate is below 30%; Described inorganic fluorescent powder body is the combination of ZnS:Mn and Y3A15O12:Ce or (Y, Gd) 3A15O12:Ce; The weight of described Y3A15O12:Ce or (Y, Gd) 3A15O12:Ce is 0.5% of ZnS:Mn weight; Compacting, after mixing raw material, by mould extrusion modling; Described squeeze pressure is 5.5MPa.
The mean particle diameter of inorganic fluorescent powder body is less than the mean particle diameter of fluororesin powder, and described size ratio is 1:5.
The invention has the beneficial effects as follows:
By technical scheme of the present invention, in inorganic fluorescent powder body, include a certain amount of Y3A15O12:Ce or (Y, Gd) after 3A15O12:Ce, its colour balance benchmark is a little less than only using ZnS:Mn and ZnS:Mn to account for the colour balance benchmark that fluororesin powder weight ratio is 0.3%-13% in former technical scheme, but the irradiating illumination light time in fluorescence endoscopic mirror system, can make the fluorescence intensity that produces from subject and the ratio of intensity of reflected light improve, thereby can ignore the impacts such as electrical noise, accurately the colour balance of fluorescence endoscopic mirror system is adjusted.
Can reduce fading extent, thereby obtain fluorescence radiation characteristic steady in a long-term.
The specific embodiment
Describe by the following examples technical scheme of the present invention in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
A manufacture method for fluorescent object, preparation raw material, includes preparing plastic powder and mixes with inorganic fluorescent powder body; The weight of described inorganic fluorescent powder body be plastics powder weight 5%; Described plastics powder is fluororesin powder, and extrusion modling hole rate is below 30%; Described inorganic fluorescent powder body is the combination of ZnS:Mn and Y3A15O12:Ce or (Y, Gd) 3A15O12:Ce; The weight of described Y3A15O12:Ce or (Y, Gd) 3A15O12:Ce is 0.5% of ZnS:Mn weight.The mean particle diameter of inorganic fluorescent powder body is less than the mean particle diameter of fluororesin powder; Described size ratio is 1:5.
Compacting, after mixing raw material, by mould extrusion modling; Described squeeze pressure is 5.5MPa.
In mixing, use the prilling granulator with hobboing cutter, with per minute 2500, turn mixed processing 10 minutes.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification and replacement to these embodiment, scope of the present invention is by claims and be equal to and limit.
