Description

A kind of ageing-resistant LED cover material
Technical field
The present invention relates to a kind of material of lampshade, especially a kind of ageing-resistant LED cover material, belong to LED lamp technology Field.
Background technology
With the development in epoch, the continuous quickening of modernization construction paces, the living standard of people improves constantly, to road Illumination and lighting engineering demand are also gradually increased.LED light source belongs to spot light, and spot light illumination range is narrow and meeting human eye generation is dizzy The influence of light, typically acted on by the light scattering of lampshade, spot light is transformed into area source, in favor of the routine use of people.
But it is in LED road lamp shade in the prior art, still to use traditional cloche more, and with LED street lamp increasingly After more use solar panel, wind energy or battery equal energy sources is as administration of power supply, for LED street lamp energy utilization degree Propulsion will seem particularly necessary.
For existing LED cover material, it generally has following defect, and density of material is big, acquisition price it is high and Cost is high, quality weight and cost of transportation height;Ageing resistace is poor;Anti-wear performance and toughness are poor.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of ageing-resistant LED cover material.
Technical scheme is as follows:A kind of ageing-resistant LED cover material, it is characterized in that, the lampshade is double-layer vacuum Glass is made, and the cover surface is provided with aging-resistant layer, and each component that the aging-resistant layer includes following parts by weight is prepared:It is poly- It is urethane 40-60 parts, POE resin 20-35 parts, ultra-violet absorber 1-3 parts, antioxidant 0.5-2 parts, crosslinking agent 1-4 parts, transparent Filler 5-8 parts, poly- diethanol 1-4 parts, light stabilizer 1-3 parts, light diffusing agent 4-6 parts, plasticizer 4-8 parts.
The crosslinking agent is peroxidized t-butyl perbenzoate.
The transparent filler is transparent glass fiber.
The light diffusing agent is organosilicon light diffusing agent.
The polyurethane material added in the present invention, its hardness range is wide, and intensity is high, and the adjustable extent of performance is big;It is multinomial Physical and mechanical properties index can be changed, so as to meet within the specific limits by the selection and the adjustment of formula to raw material User is required the difference of product properties;It is wear-resisting, there is the good title of " abrasive rubber ";Oil resistant, PAUR elastomer it is resistance to Oiliness is not less than nitrile rubber, suitable with polysulfide rubber;Ozone resistance is excellent;Shock-absorbing, radioresistance and resistance to permeability are good.
POE molecular structures are similar to ethylene propylene diene rubber (EPDM), therefore POE can also have ageing-resistant, resistance to ozone, resistance toization The excellent properties such as medium are learned, by being crosslinked to POE, the heat resisting temperature of material is enhanced, and permanent deformation reduces, and stretching is strong The Main Mechanicals such as degree, tearing strength all have significant improvement.
Organosilicon light diffusing agent belongs to the light diffusing agent of organic, be it is a kind of with silica key connection, 3-D solid structure This light diffusing agent sheets of polymer microballoon are added in the resin of unlike material, meeting is with a kind of trickle as a kind of white powder Clear glass spheroid be uniformly dispersed in matrix, by the difference of the refractive index with different substrate materials, light source penetration is entered Row refraction, changes the course of light, reaches the purpose of even light and printing opacity, while meet the needs of haze value and light transmittance.
Organosilicon light diffusing agent, relative to inorganic light diffusing agent, diffuser efficiency it is high and with matrix resin compatibility it is good, Good dispersion, proportion are small, water absorption rate is low, drying hydrophobicity is good, translucency more balances with even photosensitiveness;Relative to conventional acrylic system Light diffusing agent, light diffuser efficiency is high, addition is low, excellent heat resistance, and brightness is high, meanwhile, it is capable to keep preferable light transmittance;Phase For acrylic acid series light diffusing agent, heat resisting performance is more preferable, and lamp hole lamp house lampshade service life is longer, and light diffuser efficiency Higher, addition is relatively low.
LED road lamp shade composite provided by the invention is realizing high transmission rate and high scattering simultaneously, improves The fastness and durability of lampshade, light irradiated area being improved, mechanical property and case hardness have clear improvement, while further The defects of overcoming reunion, halation, blackening, there is the wide market space.
