Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The embodiment of the present invention provides a kind of polycarbonate composite material composition of enhancement type LED lamp cover, comprises the following component of each mass parts:
Its median surface wild phase is at least one in nano oxidized aluminium grain or whisker.
Adopt above-mentioned polycarbonate composite material composition of the present invention, first wherein assist in major ingredient and be added with polymethylmethacrylate and PMMA, PMMA high-performance optical classes and grades in school liquid crystal material, main application liquid crystal display light guide plate, fiber optic materials, it is high brightness optimum in resin material, there is very excellent bright performance, using by arranging in pairs or groups with polycarbonate, the optical property of polycarbonate major ingredient can be promoted.
Doped with on the basis of light-scattering master batch and inorganic nano-particle, the present invention adopts further and adds the nano oxidized aluminium grain of interface wild phase or whisker; Wherein, nano aluminium oxide can phase transformation in the later stage, resin solidification was shaping, can also reinforced transformation toughening effect; In addition the thermal mismatching of nano aluminium oxide itself makes alumina grain be in pressured state in the composite, crystal grain boundary place not easily forms tiny crack, but form half coherence and codoped structure, by increasing the crystal structure in resin material, be similar to the bit architecture of optical fiber, reduce the power loss in photon spread process, realize the degree promoting light diffusion and penetrate.And the whisker of minute quantity is after alloying addition, for the typical quantum confined effect that whisker itself has, photon diffusion ability can be promoted; And the trace of whisker fills the mechanical property that can also be conducive to promoting composite resin material, mechanicals efforts is generally difficult to through whisker, more easily walk around whisker and the surface and expanding of trying one's best, namely deflect, enhance the mechanical property of resin material, simultaneously when whisker or fiber are pulled out, need external force work done, also serve enhancement.After adding above-mentioned interface wild phase in composite resin material, because the random of interface wild phase is uniformly distributed in the process of light diffusion simultaneously, be conducive to the angle strengthening light diffusion, make light-emitting area broader and even.
Meanwhile, state on the invention in resin composite materials and add methoxyl group polyglycol acetic acid, overall dispersing property can be promoted; Because this is added with nano inorganic particle as nano titanium oxide, nano silicon, nanomete talc powder etc., light-scattering master batch in resin major ingredient, and the interface wild phase of inorganic components; These addition materials need after adding to ensure stable dispersing property, be easy to make the dispersiveness of auxiliary agent not enough because nano-particle material itself has the characteristic being very easy to reunite, and cause the homogeneity of material in final integral inadequate, the phenomenons such as the appearance halation causing light to spread or blackening; So based on above-mentioned purpose, methoxyl group polyglycol acetic acid in the present invention, is adopted to realize the lifting of dispersing property.In its structure of methoxyl group polyglycol acetic acid, polyether backbone contains more C-O key, C-O bond dissociation energy, lower than long-chain hydrocarbon polymkeric substance C-C dissociation energy of bond, and polyether backbone contains more propoxy-(PO) further, pending methyl group on propoxy-(PO) makes main chain is full of branch point, methyne hydrogen on branch point is more easily taken away, and pending methyl group also can weaken the bond energy of C-C key in polyether backbone and C-O key, thus makes the thermostability of polyether backbone be deteriorated further.Just start to occur by thermal destruction at higher than the temperature of 160 DEG C, and composite resin material preparation process condition is controlled, the temperature condition of the processes such as extruding pelletization is generally between 250 ~ 270 DEG C, can higher than its degradation temperature of methoxyl group polyglycol acetic acid, therefore end-group structure is ketone, the thermal degradation products of aldehyde, alcohol and ether to use the degraded in the process of preparation of this material to produce, and greatly can promote the diffusion of the inorganic components of interpolation in the stage of degrading; The simultaneously characteristics of plasma such as acid dissociation of methoxyl group polyglycol acetic acid, electric charge on metal nanoparticle surface band can be given, between metal nanoparticle, produce the stabilization of Coulomb repulsion, thus stop the reunion between metal nanoparticle, be also beneficial to lifting dispersion effect.Preferred in the present invention further, the weight-average molecular weight of methoxyl group polyglycol acetic acid is 800 ~ 2000; When its weight-average molecular weight is lower than 800, sterically hindered effect reduces, and is unfavorable for the dispersiveness improving nano particle; Higher than 4000 time, intermolecular reactive force increases, and molecular chain is elongated, and intermolecular winding probability increases, thus reduces thermal degradation.
And after stating embodiment on the invention further, after collocation among the material composition of the comparatively single polycarbonate of wherein material own has PMMA and above-mentioned organic dispersing agent and inorganic additives, the compatible stability of material monolithic will inevitably be affected; So add MAH-g-EPDM in the present invention further as compatilizer, promote the interface compatibility of each material.Reason is, the EPDM of one own has minimum proportion in the middle of all rubber, it can absorb a large amount of fillers and oil and influencing characteristic is little.Therefore, when its filling effect is the most excellent, just can contribute to the combination with other functional component auxiliary agent, and reduce the unbalance impact of a large amount of additive of polycarbonate material; Its two EPDM can overcome melt fracture problem when basic granulation, curing molding in whole system, avoids " tiger spot " defect that occurs on the surface of resin and causes surface-duided wave Slippage, filamentary silver, current mark etc.Further EPDM adopts maleic anhydride graft, forms block structure, and adds more reactive bonding groups, be beneficial to the compatible combination between each material.
Further state on the invention in the process of embodiment, adopted by inorganic nanoparticles different granularity type to arrange in pairs or groups, adopt coarsness: middle granularity: the varigrained inorganic nanoparticles ratio of fine granularity three kinds is 4 ~ 6:2 ~ 3:1; Wherein because nano inorganic particle own is roughly in the particle size range of 10 ~ 100nm, the type of three of about 100nm, about 50nm, about 10nm kinds of different-grain diameters can be roughly selected to carry out composite use in the process implemented in the present invention, its reason is that can strengthen resin interior lights diffusion orientation further carries out without silicon deviation, strengthens the homogeneity of light diffusion; And because resin material own is as in the use of LED lamp cover, use after for some time, can occur to hand over poly-, aging etc. between some compositions in material itself, the light after easily causing occurring spreads and unevenly occurs the problems such as halation; The particle diameter of nano particle is transformed to three kinds of different-grain diameters and fills by the present invention, can increase the random degree of interior lights diffusion; When use for some time after, after material itself there occurs character and structure degradation, these inorganic particles itself do not change, can light stable diffusion random directivity, weaken the defects such as halation.
Certainly in the present invention further implementation process, in order to ensure can have very good composite performance further in matrix material, wherein other functional agent such as oxidation inhibitor, under LED lamp cover service requirements, add anti ultraviolet agent etc., these those skilled in the art can add according to required service requirements.
Wherein, in functional agent, can also coumarin fluorescent brightener be added in the present invention, be conducive to that material is received and excite incident beam to produce fluorescence, thus make material itself produce exciton auxiliary light emission, promote the intensity that light diffused transmission from matrix material is gone out, strengthen transmittance.
