Description
Technical field
The present invention relates to a kind of plastic optical fiber material, specifically, relate to a kind of plastic optical fiber material that uses warm variable pigments.
Background technology
Plastic optical fiber (Plastic Optical Fiber is called for short POF) claims polymer optical fiber (Polymer Optical Fiber also is called for short POF) again, is the novel biography light medium that adopts polymeric material to be prepared from.The research of POF starts from twentieth century sixties, and fiber core layer and covering are all made with resin and plastic.
The resin that adopts has polystyrene (PS), polymethylmethacrylate (PMMA), polycarbonate (PC), fluoroplastic or poly--4-methyl-amylene-1 (TPX) etc.Plastic optical fiber is made data transmission media except can be applicable to the communications field, also is widely used in optical fibre art and craft, toy, clothes, fields such as fiber optic christmas tree and plastic optical fiber illumination.
The plastic optical fiber illumination is a kind of illumination new technology of novelty, because of it has photodetachment, energy-conservation, compliance with environmental protection requirements and long service life, easy to maintenance, advantage such as later maintenance cost is low, and be widely used in aspects such as all types of billboards, indoor and outdoor decoration, water scenery, courtyard garden and road lighting, can also be used for fields such as industry, medical treatment and scientific research.
Usually plastic optical fiber light beam change in color is to realize by the colour disk of conversion different colours, and the present invention is owing to having adopted the plastic optical fiber material that contains warm variable pigments, so also can change the color of plastic optical fiber when the solid color light source.
Summary of the invention
The invention provides the plastic optical fiber material that a kind of temperature becomes, under different temperature, plastic optical fiber can change and multiple color, has increased the decoration functions of plastic optical fiber.
In order to realize the object of the invention, the invention provides the plastic optical fiber material that a kind of temperature becomes, it is made up of 99.9～90 parts by weight resin and 0.1～10 weight portion temperature variable pigments, and described resin is polystyrene (PS), polymethylmethacrylate (PMMA), polycarbonate (PC), fluoroplastic or poly--4-methyl-amylene-1 (TPX).
Described temperature variable pigments is organic class, mineral-type or liquid crystal type thermo-sensitive material, all belongs to the thermo-sensitive material of thermochromism.
Color can be yellow, green, blueness, golden red, large red, rose, purple, brown, black, color such as blackish green, peacock blue under the state of colour developing, and changes between the above-mentioned color.
Mineral-type mainly is a transistion metal compound, generally is the polycrystal of multiple metal oxide.Its change color is because crystal formation changes, the coordination solid changes or the variation of ligand solvent molecular number causes, have a few compounds to be since in the solution molecular structure balance of complexation equilibrium or organometallics cause, also having some compounds is to cause change color by distillation, fusion, decomposition, chemical combination, redox reaction.Some solid metallic alloy, mercury compound, copper complex, nickel complex have thermo-color character.The heat-sensitive variable colour of metal alloy is to have the disordering of crystalline network or oxide formation to cause; The heat-sensitive variable colour of mercury compound is low temperature bata configuration being transformed to high temperature α configuration; The thermo-color reason of complex compound is that configuration changes or ligand quantity and kind change.Negative ion and choice of Solvent also have certain influence to change in color in the complex compound.The chelate that some triaryl methane complexon aqueous solution and some metals form also has heat-sensitive variable colour character.

5Expression has the space of trace to exist on plumbous position, introduces aforementioned M element compound to this space, even introduce seldom amount, its thermochromatism also can strengthen.Along with temperature raises, tone is from orange-red orange-dark brown variation, and hot tracing property is good, does not have thermal process.The inorganic thermochromatic material heatproof of this class, durable, fast light photograph have enough reversible repetition life-spans, have good hybrid process simultaneously.
Organic compound quantity with heat-sensitive variable colour is more, as the electronq donor class.This class chromotropic dye mainly comprises triarylmethane compound, Material of Fluoran, spiro-pyrans class, Furanones, pyridines, phenothiazines etc., and its heat-sensitive variable colour mechanism is different.The thermo-color of spiropyran derivatives is through the ion resonance structure being arranged, i.e. C spiral shell-O bond rupture.The spiral shell carbon atom is a sp3 hydridization when closed loop before being heated, and the back open loop of being heated becomes the ionization structure, and the spiral shell carbon atom is a sp2 hydridization, and whole molecule is in the conjugation balance, makes the absorption spectrum skew, darkens.The thermo-color process of other compound is via various intermolecular balances: the Acid-Base balance, and enol-ketone balance, balance or constitutional balance cause between steric isomer.That studies at present is maximum, and organic thermochromatic material that application prospect is arranged most is a kind of multi-component compound.Its heat-sensitive variable colour temperature range is-200 ℃～200 ℃.
Electronq donor also claims leuco dye, and when temperature variation and electron acceptor generation reversible thermochromic reaction, the transfer by its electronics absorbs or the light of the certain wavelength of radiation, change in color has just been arranged on apparent.The effect of solvent can also be played the effect of control discoloring temperature except dissolving electron donor and electron acceptor, solvent types and consumption are very big to thermo-color temperature effect.In order to improve some character or to reach different thermo-color effects, also to add the adjuvant of suitable kind, suitable consumption.The characteristics of the different choice of these several components and degree of freedom, variable color significant degree and the price factor etc. that cooperate the selectivity that can realize discoloring temperature, color combination, extremely promising.Japan PILOT printing ink Co., Ltd. developed this type of thermo-sensitive material in 1973, before and after 1980 its product Metamocolor was squeezed into the domestic and international market, and its color change and variable color sensitivity are all fine, but photostability is not good enough, is not suitable for tanning by the sun under the long-time sunlight.
The liquid crystal type thermo-sensitive material: cholesteryl liquid crystal has layered molecular structure, and molecular long axis is parallel to each other in the layer, and each layer molecular axis direction and adjacent bed molecular axis direction be slightly skew all, makes liquid crystal molecule shape structure in the shape of a spiral, thereby shows unique optical property.If n is the refractive index of liquid crystal, p is a pitch, and the optical wavelength of liquid crystal is n * p so.When lambda1-wavelength was consistent with the optical wavelength of liquid crystal, liquid crystal just demonstrated the light of particular color, and this also cries the selective light scattering of liquid crystal.The pitch of most of cholesteryl liquid crystals has very strong dependence to temperature simultaneously, the wavelength of temperature variation selective light scattering just changes a lot, general p raises with temperature and diminishes, the scattering light wavelength moves to shortwave, color is corresponding to change to purple from red, orange, yellow, green, and the temperature reduction changes to red from purple again.
Described weight portion can be this area unit of weight commonly used, such as gram, kilogram, ton, two etc.
Wherein, preferably, it is made up of 99～98 amount part resins and 1～2 warm variable pigments.
MFR (melt flow rate) for thermoplastics is meant that the every 10min of plastic melt is by the quality of standard mouth mould under certain temperature and load.Higher MFR can increase the flowability of plastics, helps the processing of optical fiber; But MFR can not be too high, and too high MFR can cause the weight-average molecular weight of plastics low, poor mechanical property, and the MFR of resin of the present invention is many between 0.5～60g/10min.
