Abstract
The utility model relates to a novel EVA (ethylene vinyl-acetate copolymer) adhesive film of a solar cell, which comprises an adhesive film body, wherein the upper surface and the lower surface of the adhesive film body are respectively provided with a raised textured layer; and a frosted layer is arranged on the textured layer. Due to the design of the frosted layer, the novel EVA adhesive film of a solar cell avoids the bonding during the joint of the adhesive film and a cell, and greatly reduces the phenomenon that bubbles are caused during component lamination; and the novel EVA adhesive film has a simple structure.
Description
Technical field
The utility model relates to the field of solar photovoltaic assembly, especially a kind of novel solar battery EVA glued membrane.
Background technology
The EVA glued membrane is a kind of heat cured membranaceous PUR, is not clamminess under the normal temperature, is convenient to operation, and under molten condition, it produces to bond with silicon wafer, glass, TPT becomes solar panel.EVA is the copolymer of ethene and vinyl acetate, has good pliability, resistance to impact, elasticity, optical transparence, low temperature around song property, adherence, environmental stress crack resistance, weatherability, corrosion resistance, heat seal property and electrical property etc.
The EVA glued membrane that uses at present is the light film, and its any surface finish is bonding easily between film and the film, often needs lining paper to isolate, and is to cause pinning phenomenon easily when solar cell combines, and causes arrangement out of shape.
Summary of the invention
The utility model technical issues that need to address are: in order to overcome the above-mentioned middle problem that exists, a kind of novel solar battery EVA glued membrane is provided, it is simple in structure, is difficult for out of shape in the use.
The utility model solves the technical scheme that its technical problem adopted: a kind of novel solar battery EVA glued membrane; Comprise the glued membrane body, described glued membrane body upper surface and lower surface are equipped with protruding flower-pattern layer, and flower-pattern layer is provided with the frosted layer; Can increase the surface area of glued membrane effectively; The structure of frosted can reduce the cementability with cell panel, when the rolling glued membrane, need not to use lining paper, has reduced cost.
Described glued membrane body and flower-pattern layer are integral structures, carry out pressure roller through the roller that has decorative pattern.
The decorative pattern of said flower-pattern layer is to be triangular taper.
The thickness of said frosted layer is 0.3～0.5mm.
The beneficial effect of the utility model is: described solar cell Novel EVA adhesive film, adopt the design of frosted layer, and bonding and occur the phenomenon of bubble when having significantly reduced laminated compenent when having avoided glued membrane to combine with the battery sheet, it is simple in structure.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the overall structure sketch map of the described novel solar battery EVA of the utility model glued membrane.
Accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1, glued membrane body, 2, flower-pattern layer, 3, the frosted layer.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Novel solar battery EVA glued membrane as shown in Figure 1 comprises glued membrane body 1, all is pressed with protruding flower-pattern layer 2 at glued membrane body 1 upper surface and lower surface; The decorative pattern of flower-pattern layer 2 is triangular taper; Glued membrane body 1 is structure as a whole with flower-pattern layer 2, and flower-pattern layer 2 is provided with frosted layer 3, when solar cell package, uses the EVA glued membrane with frosted layer 3; Because frosted has improved the surface area of glued membrane; Increased the adsorptivity of solar cell and EVA glued membrane, avoided the displacement of bubble generation and glued membrane, frosted layer 3 thickness are 0.4mm.
The described novel solar battery EVA of the utility model glued membrane; Raw material is selected the EVA material for use; Successively through just using solar cell package after mixer, extruder, cutting edge equipment, coating equipment, dehumidification equipment, the rolling of rolling equipment; Can play anti-reflection light, effect such as the vapour that blocks water, uvioresistant, can guarantee useful life of solar module.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
