Description

Nano compound agglomerate of a kind of outdoor lamp special use and preparation method thereof

Technical field

The present invention relates to a kind of nano compound agglomerate, specifically, it is the nano compound agglomerate of the outdoor lamp special use that is prepared from by fatty polyamide, inorganic nano material, mineral filler, organic additive, belongs to outdoor lamp material field.

Background technology

Plastics because material is light, insulation, wear-resisting, corrosion-resistant, attractive in appearance, complete processing simple, low cost and other advantages, and is widely used in the open air.But during plastics (belonging to the macromolecule resin class) use out of doors, be subjected to the ultraviolet radiation of high energy meeting generation photoaging for a long time and cause degraded, degradation product reacts with oxygen or other activeconstituents in air, thereby etiolation appears, glossiness and physical and mechanical properties all will reduce significantly simultaneously, cause reducing its actual service life [Zhou Dagang, Xie Gecheng at last, Deng. ageing of plastics and anti-aging technology [M]. Beijing: China Light Industry Press, 1992.].

At present, the master batch of the general purpose grade weather resistant plastics of domestic and international market circulation mainly is to reduce the photoaging degree of plastics by adding organic photostabilizer, but organic photostabilizer belongs to the unfriendly material of environment, himself also can degradation with aging, degraded product has toxicity mostly, serious to environmental disruption, and plastics also will cause its weather-proof afunction along with the degraded of organic photostabilizer, so this type agglomerate material engineering afterwards will be restricted gradually until eliminating in using.

Nano material is that particle dia is distributed in the ultrafine particulate between 1nm～100nm.Nanoparticle is the particle between elementide and submicron particles, its interface is formed primitive and is accounted for larger proportion, the crystal that both had been different from long-range order, it is unordered to be different from long-range again, short range order noncrystal, but be in the higher state of the degree of disorder, this state makes nanoparticle produce unique physics and chemical property: small-size effect, surface effects, quantum size effect, macro quanta tunnel effect and dielectric confinement effect.These special effects make rutile type nano TiO ₂Had ultraviolet shielded ability Deng the inorganic semiconductor nano material.

When illumination on semiconductor particle, its photon energy is during greater than energy gap, the optical excitation electronics transits to conduction band from valence band and produces electronics (e ^-) and hole (h ⁺), and electronics and hole are easy to again compound or caught by impurity in the nanoparticle or other defect, and release energy with the form of heat energy or light, thereby realize absorbing ultraviolet process.Causing the maximum excitation wavelength of the light of this process can try to achieve according to the energy gap Eg of material:

$\mathrm{Eg}=\mathrm{hv}=h\×\frac{c}{\mathrm{\λ}}$

$\⇒\mathrm{\λ}=\frac{\mathrm{hc}}{\mathrm{Eg}}$

In the formula: h-planck constant, 6.626 * 10 ^-34JS

The c-light velocity, 3.0 * 10 ⁸M/s

According to above-mentioned formula, with rutile type nano TiO ₂Be example, its energy gap Eg is 3.0ev, can calculate TiO ₂Corresponding maximum excitation wavelength is 413nm.In theory, wavelength can both be absorbed by semi-conductor nano particles less than the light of maximum excitation wavelength, therefore, nano-titania particle UV-light is had wide absorption band.

But, also do not have at present to find about using the report that the inorganic nano-particle manufacturing has the outdoor lamp special-purpose nanometer composite master batch of higher weathering resistance, environmentally safe.

Master batch of the present invention is according to GB/T 16422.2-1999 standard, adopt the xenon lamp climatic cabinet that the standard testing batten of master batch of the present invention and master batch preparation is carried out 28 days weather accelerated weathering tests: according to its value of chromatism of GB/T 15596-1995 standard testing less than 3, according to its glossiness conservation rate of GB/T 8807-1988 standard testing more than 85%, according to GB/T 1843-1996 standard testing sharp notch shock strength conservation rate more than 80%, according to the conservation rate of GB/T 1040-1992 standard testing tension fracture unit elongation more than 90%; The conservation rate of its value of chromatism, glossiness conservation rate, sharp notch shock strength conservation rate, tension fracture unit elongation all is better than the market circulation product and does not add the test bars of nano material preparation.

The material that adopts master batch of the present invention to prepare has overcome the shortcoming of the easy photoaging of outdoor facilities employing plastic fittings: because of nano material has been improved rutile type nano TiO through inorganic coating and organic process technical finesse ₂Deng the dispersiveness of inorganic nano-particle in macromolecule resin, the consistency and the bonding force of inorganic nano material and macromolecule resin have been improved, make nanoparticle and macromolecule resin, inorganicly in nanometer range, combine with organic phase, make to form chemical bonding force between two-phase interface, thereby can bring into play the nano effect and the synergistic effect of inorganic nano material.Bring into play rutile type nano TiO simultaneously ₂Synergy Deng ability and organic photostabilizer of the wide band of inorganic nano material, long-acting shielding ultraviolet rays blocks outdoor facilities degradation with aging reaction chain increases substantially the weather-proof ability of outdoor facilities.And because of having added inorganic nano material in the master batch raw material of the present invention, the then corresponding minimizing of then organic photostabilizer addition can reduce the pollution to environment relatively.

Because the singularity of chemical field is not passed through the support of a large amount of shaker tests, those of ordinary skill in the art can not know by inference apparently just can produce the material with these mixing functionss after having some materials with function hybrid process.Can not derive apparently equally and add outdoor lamp specific complex master batch that inorganic nano material with shielding ultraviolet rays function is prepared from and the outdoor lamp of preparation can have the function of shielding ultraviolet rays, the function of anti-light aging too; Simultaneously the add-on of the kind that adds of inorganic nano material, inorganic nano material and in preparation process inorganic nano material whether need pre-treatment, which step to add the mode of inorganic nano material and adding in, obviously just can not derive out.

The outdoor facilities plastic fittings of nano compound agglomerate preparation of the present invention, effect with anti-light aging has excellent weather resistance, can prolong the actual service life of outdoor facilities, and the degraded product environmental pollution is little, for outdoor facilities master batch and material provide a kind of new selection.

Obviously, according to foregoing of the present invention,,, can also make modification, replacement or the change of other various ways not breaking away under the above-mentioned basic fundamental thought of the present invention prerequisite according to the ordinary skill knowledge and the customary means of this area.
