Description
Technical field
The present invention relates to a kind of luminescent plastics composition, say further, relate to a kind of high light polystyrene composition and preparation method thereof.
Background technology
Polystyrene (PS) is polymerized by styrene monomer, Industrial products mainly adopt mass polymerization and suspension polymerization preparation, the polystyrene raw material source is abundant, polymerization technique is simple, material has light weight, inexpensive, characteristics such as water regain is low, tint permanence, dimensional stability, electrical property excellence, the goods transparency is good, is easy to processing, is mainly used in instrument, household electrical appliance, toy for children, stationery packing etc.,, use very extensive.But under some special occasions, night time operation for example, enclosed environment illumination is interrupted or the like suddenly, just need have the meter key button, switch panel, socket panel, station location marker of the function of self-lighting etc., carries out normally or the timely processing of accident with the assurance operation.In addition, camp equipment and instrument etc. need special shock resistance.Therefore, under this class occasion, needing not only can luminous, and toughness will be good especially can be luminous polystyrene resin.
The sixties in 20th century, SrAl

2+After the twilight sunset phenomenon of material was found, people were to europium ion (Eu
2+) method that mainly concentrates on by adding the assisted activation ion and changing matrix structure of the research and development of activated aluminate class and silicates light-storing and emitting material improves the luminous intensity of material and prolong time of persistence.
Since the nineties in 20th century, this aluminates system or silicate systems light-storing and emitting material (are seen " light-storing and emitting material and goods thereof " third and fourth chapter, the Xiao Zhiguo chief editor, Chemical Industry Press's in October, 2002 publication) research changes the applied research stage over to by conceptual phase, this material has characteristics such as nontoxic, harmless, "dead", it is the environmental type material, particularly than zinc sulphide materials significant advantage is being arranged aspect the accumulation of energy and the characteristics of luminescence, its absorbing time is short, extinction 10～20min is more than the sustainable luminous 12h.By adopting this material, people develop luminescent ceramic, coating, printing ink, rubber, plastics, fiber, fabric etc. in succession.
Continuous development along with light-storing and emitting material, its application in fluoropolymer resin also is subject to people's attention day by day, many long-persistence luminous plastic material goods have appearred both at home and abroad in succession, be widely used in fields such as road markings, electric switch, instrument, building decoration, now most widely used long after glow luminous material with mixed with resin, mixing process in, owing to be subjected to strong friction and high shear forces, the part lattice be damaged, thereby reduce the luminous efficiency of material; The hardness of luminescent material is very high, with the metal screw friction, also can cause the material blackening in the extruding pelletization process, makes the luminosity and the degraded appearance of goods.Therefore the steady persistence high polymer product is used thermosetting resin and coating more at present, to reduce in the course of processing and height friction, high-shear between processing units, as U.S. Pat 6905634 is to be matrix with the unsaturated polyester, adding luminescent material and glass fibre enhancing are made and are coated with replica or moulded parts, and ZL00132574.4, US5874491, US5858495 add to be coated on matrix surface after luminescent material mixes in coating.Particle diameter that also can be by selecting luminescent powder or reduce the blackening degree that add-on alleviate material in addition, as U.S. Pat 6,716,368 add 0.01%～2% particle diameter prepares luminous polycarbonate less than the luminescent material of 10 μ m, but the luminescent properties of this material is very poor, because the size and the add-on of used luminescent powder are just depended in the brightness of luminescent material, luminescent powder particle diameter luminous intensity big more or the big more material of add-on is high more.ZL99127572.1 reduces the degree of luminescent material blackening with prefabricated luminous masterbatch, only is suitable for general-purpose plastics, can't resolve the problem of the easy blackening of the course of processing for fragility and the very big resin of hardness.
In addition, add the bigger phosphor of a large amount of relative grain size in polymkeric substance, the bad dispersibility in Plastic Resin can reduce the mechanical property of luminescent material, particularly impelling strength and reduce, and will have a strong impact on and limit the use range of luminescent material.Therefore the luminescent plastics composition is for fear of serious following general of mechanical property in the prior art, and the umber of the luminescent material of its interpolation is all lower, is that 100 weight parts generally are no more than 5 parts in matrix plastic.
Summary of the invention
When adopting traditional blending method to prepare high light polystyrene, destroy the crystalline network of luminescent powder material easily, make the luminescent material oxidation simultaneously, make long-persistence luminous degradation, the goods variable color of polystyrene; The mechanical property of the luminous polystyrene of the bad influence of dispersion of while phosphor.
The present invention is directed to above problems of the prior art, be intended to obtain a kind of high light polystyrene composition that when having good luminous performance, has high tenacity and good appearance.
Therefore, the purpose of this invention is to provide a kind of have good luminous property and high tenacity and non-discoloring high light polystyrene composition.
Another object of the present invention provides the preparation method of described high light polystyrene composition.PS resin and luminescent material realize that disposable blend extrudes in this method, can increase work efficiency greatly, realize the good mixing dispersion effect simultaneously.
The contriver finds in the process of research luminescent plastics, is added in finely disseminated elasticity powdered rubber in the plastics and can helps to reduce shearing friction in the blend process, reduces the destruction of mechanical blending to the luminescent material lattice, prevents the oxidation of luminescent material; And assistance improves the dispersion of luminescent material in plastic substrate simultaneously.Make that luminescent material can be because of influencing its illumination effect in plastic substrate in processing and scattering problem.Owing to reduced the oxidation of luminescent material, can stop the metachromatism after goods are extruded simultaneously, make luminescent plastics have good appearance.And the adding of powdered rubber can also make the toughness of luminescent plastics be greatly enhanced, thereby the add-on of luminescent material is greatly enhanced, and is that 100 weight parts can reach more than 5 parts in the matrix polystyrene generally.
