Summary of the invention
Purpose of design: design a kind of both had excellent weather resistance and reliable sealing property, again can be independently as encapsulating material for solar cell, can make again the solar energy module core being shaped work out of doors for a long time and can prevent the special shaped material of solar module shell and the making method that steam infiltrates simultaneously.
Design: in order to realize above-mentioned purpose of design.The present invention adopts the design of modification hard PVC as solar energy module sealing material, is technical characteristics of the present invention.The object of design is like this: it changes the PVC that those skilled in the art think for a long time and sticks with paste due to good dispersion property, can only be used for soft material field uses, as leatheroid, vinyl toy, soft trade mark, wallpaper, paint, foamed plastic etc., can not serve as the technology prejudice of solar cell sealing shaped material.The application Fan Qi road it, adopt PVC to stick with paste as solar cell sealing shaped material, not only can make solar panels may need to be formed in different shape according to user, and the solar cell of formed thereby is easy to cast, good, heat-resisting, the shock resistance of translucent effect, anti tear, and can realize a small amount of, many kindizations and produce, the more important thing is that this material realized long-term hermetically sealed, the round-the-clock weather-proof use out of doors of solar cell sealing.
The application adds and is used for absorbing ultraviolet absorption agent in PVC sticks with paste; because UV light absorber can absorb sunlight or fluorescence source middle-ultraviolet lamp part; and this body structure does not change; it can discharge high-octane ultraviolet luminous energy energy transform into heat energy or nondestructive longer light wave; thereby protection is added with the material of UV light absorber and exempts from ultraviolet ray destruction; in PVC sticks with paste, add UV light absorber and can effectively stop ultraviolet ray in the sunlight destruction to solar cell sealing module, extend the work-ing life of solar module.
The object that the application adds oxidation inhibitor in PVC sticks with paste is: because the PVC paste plastics after plasticizing are easily aging under the factor effects such as light, heat, oxygen, solvent, auxiliary agent, HCl, i.e. degraded or crosslinked, degenerates its physical and mechanical properties, reduction of service life.The application PVC adds oxidation inhibitor effectively to suppress or reduces the macromolecular thermooxidizing of plastics, photooxidation reaction speed in sticking with paste, improve significantly heat-resisting, the light fastness of the PVC paste plastics after plasticizing, delay degraded, weathering process that the PVC after plasticizing sticks with paste plastics, improve the weather resisteant that PVC sticks with paste made solar module, extend the PVC paste plastics work-ing life after plasticizing.
The object that the application adds low temperature softening agent in PVC sticks with paste is: because low temperature softening agent and PVC paste resin have good consistency, plasticization effect is good, be difficult for segregation, be difficult for oozing out, and low temperature softening agent can reduce the second-order transition temperature that the PVC after plasticizing sticks with paste plastics, make its snappiness good, the cold tolerance that can improve the PVC paste plastics after plasticizing, makes it still have good use properties in cold district.
The object that the application adds stablizer in PVC sticks with paste is: modification hard PVC at high temperature plastify or high temperature under use, very easily emit HCL, form unsettled polyene structure.Meanwhile, HCL has self-catalysis, can make PVC further degrade.In addition, if aerobic exists or have iron, aluminium, zinc, tin, copper and cadmium plasma to exist, all can be to the PVC katalysis of having degraded, accelerate that it is aging.Therefore will there are various bad phenomenon in plastics, as variable color, distortion, be full of cracks, physical strength decline, edge degradation, embrittlement etc.In order to address these problems, PVC sticks with paste in plastics must add different varieties, the stablizer of different numbers.
Technical scheme 1: the special shaped material of a kind of solar module shell, the special shaped material of solar module shell adopts modification hard PVC.
Technical scheme 2: the making method of the special shaped material of a kind of solar module shell, according to outdoor extreme weather conditions, in sticking with paste, adds the PVC of 100 parts of weight one or more additive.
The present invention is compared with background technology, the one, solar module shell shaped material adopts hard PVC, and solar module shell shaped material adopts hard PVC, and sealing material adopts PVC to stick with paste, not only there is good UV resistant, low temperature resistant, weathering resistance, and fire-retardant V-2 to the V-0 level that reaches; The 2nd, can be according to user's different demands by the be shaped profile of required solar panels of solar module core, fundamentally change and thought that modification hard PVC can not serve as the technology prejudice of solar cell sealing shaped material since the normal phase of those skilled in the art.
