Abstract
The invention relates to a solar cell forming material with excellent weather resistance and reliable sealing property and a manufacturing method of the solar cell forming material. The solar cell forming material adopts a PVC (polyvinyl chloride) paste material, and has the advantages that firstly, PVC paste is adopted as a forming material for sealing of a solar cell module, so that the solar cell forming material not only has good ultraviolet resistance, low-temperature resistance and weather resistance, but also reaches V-2 to V-0 grade of flame retardance; secondly, shapes of needed solar panels can be formed by using a solar cell module core according to different needs of users, so that the technical biases that those skilled in the art always consider that the PVC paste material can not be used as the forming material for sealing of the solar cell can be fundamentally changed.

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 cell being shaped work out of doors for a long time and can prevent solar cell shaped material 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 PVC thickener 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: PVC thickener 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: a kind of solar cell shaped material, solar cell shaped material adopts PVC thickener.
Technical scheme 2: a kind of making method of solar cell shaped material, 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 compared with background technology, the one, adopt PVC to stick with paste the shaped material as solar module sealing, not only there is good UV resistant, low temperature resistant, weathering resistance, and fire-retardant V-1 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 PVC thickener can not serve as the technology prejudice of solar cell sealing shaped material since the normal phase of those skilled in the art.
