Embodiment Construction

[0052] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0053] In order to verify the various performances of the flame-retardant white EVA packaging film of the present invention, 4 groups of flame-retardant white EVA packaging films obtained by using four sets of data from the 1st to 4th were tested respectively, each group of EVA packaging film The specific components and proportions of the film are listed in the following table, where the content of each component is expressed as: per 100 parts by mass of EVA, the mass parts added by other components:

[0054]

[0055]

[0056] According to the relevant data of the above 10 groups of flame-retardant white EVA packaging films, the following parameters of the 4 groups of flame-retardant white EVA packaging films were obtained through experiments:

Abstract

The invention belongs to the technical field of solar photovoltaics, and relates to a solar photovoltaic flame-retardant type white EVA packaging glue film and a double-glass photovoltaic component. The packaging glue film adopts a fire retardant obtained by compounding triphenyl phosphate (TPP), nanometer calcium carbonate (Nano CaCO3) and nanometer magnesium hydroxide (Nano Mg(OH)2). According to the invention, the above-mentioned three flame retardants are compounded according to a certain proportion and mutually supplements flame-retardant defects and disadvantages, so synergistic and flame-retardant effects can be generated; and the EVA flue film achieves best flame-retardant effects and is used for packaging of the double-glass photovoltaic component, wherein the fireproofing grade of the double-glass photovoltaic component achieves the requirements of Class A.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic modules, and in particular relates to a solar photovoltaic flame-retardant white EVA packaging adhesive film and a flame-retardant double-glass photovoltaic module. Background technique [0002] If double-glass photovoltaic modules need to be installed on roofs and agricultural greenhouses, etc., fire tests (IEC61730-1 / 2, UL1703) are usually required to evaluate the module's flame retardant level Class A (the highest fire rating), Class B (medium Fire rating), or Class C (basic fire rating), fire tests include flame spread test (test method shown in Table 1) and burning block test (test method shown in Table 2). [0003] Table 1 Flame spread test [0004] [0005] Table 2 Combustion block test [0006] [0007] Double-glass photovoltaic modules generally use ordinary embossed glass for the upper layer, semi-tempered float glass for the lower layer, and EVA for the middle layer. ...
