Embodiment 1

[0035] A preparation method of a high-transparency five-component copolymerized fluorine-containing resin: first, a 10L stainless steel high-pressure reactor equipped with a stirring, temperature control, circulating heating, and circulating cooling water device is cleaned and vacuumed, and replaced with nitrogen three times until the oxygen content Less than 10ppm, vacuumize to 0.0001Mpa; then add 5L deionized water, 0.7mol vinyl fluoride, 1.2mol vinylidene fluoride, 1.2mol trifluorochloroethylene and 70g potassium perfluorobutyl sulfonate, 30g dodecane The microemulsion system composed of sodium sulfate, 100g of deionized water and 0.8g of methanol was sequentially added into the reaction kettle, and the temperature was raised to 65°C under stirring conditions; then a 1:1 mixture of ethylene and tetrafluoroethylene was introduced into the system Gas, until the pressure is 2.0MPa; finally, introduce 1g of perfluorobutyryl peroxide compound into the system to initiate the polym...

Embodiment 2

[0041] As described in Example 1, the high-transparency five-membered copolymerized fluorine-containing resin, the difference is that 5L deionized water, 0.5mol vinyl fluoride, 1.2mol vinylidene fluoride, 1.5mol chlorotrifluoroethylene and 60g of perfluorinated A microemulsion system composed of carboxylic acid ammonium salt, 30g of sodium alkylarylsulfonate, 110g of deionized water and 1.5g of chloroform was sequentially added into the reaction kettle, and the temperature was raised and stabilized to 60°C under stirring conditions; Inject a 1:1 mixed gas of ethylene and tetrafluoroethylene until the pressure is 2.2 MPa; finally, introduce 1 g perfluoropropyl acyl compound into the system by metering to initiate the polymerization reaction, and continuously feed 1:1 ethylene, tetrafluoroethylene Fluoroethylene mixed gas maintains the reaction pressure at 2.2 MPa; after the reaction is completed, the materials are separated, purified, refined, post-treated, and granulated to obt...

Embodiment 3

[0048] The high-transparency pentapolymeric fluorine-containing resin as described in Example 1, the difference is that 5L of deionized water, 1mol of vinyl fluoride, 0.8mol of vinylidene fluoride, 1.5mol of chlorotrifluoroethylene and 68g of perfluorobutane A microemulsion system composed of carboxylate, 36g of nonylphenol polyoxyethylene ether, 96g of deionized water and 0.8g of cyclohexane was sequentially added into the reactor, and the temperature was raised to 70°C under stirring; A 1:1 mixed gas of ethylene and tetrafluoroethylene was introduced until the pressure was 1.8MPa; finally, the polymerization reaction was initiated by metering 1 g of perfluoropropyl acyl compound into the system, and 1:1 ethylene was continuously introduced into the system. , Tetrafluoroethylene mixed gas to maintain the reaction pressure at 1.8 MPa; after the reaction, the materials are separated, purified, refined, post-treated, and granulated to obtain a five-component copolymerized fluorin...

Abstract

The invention relates to a high-transparency quinary copolymerization fluorine-containing resin as well as a preparation method and an application thereof, belonging to the technical field of solar photovoltaic cell materials. The high-transparency quinary copolymerization fluorine-containing resin is characterized by being copolymerized by the following monomers in the molar percentage by weightin a copolymer: 30-45% of ethylene, 40-50% of tetrafluoroethylene, 1-7% of vinyl fluoride, 2-10% of vinylidene fluoride and 3-15% of trifluorochlor oethylene. Vinyl fluoride, vinylidene fluoride and trifluorochlor oethylene are added into the binary copolymerization system of ethylene and tetrafluoroethylene in the prior art, and the light transmittance, the flexibility and the processing liquidity of the copolymer can be effectively improved by the synergistic action.

Description

technical field [0001] The invention relates to a high-transparency five-component copolymerized fluorine-containing resin, a preparation method and application thereof, and belongs to the technical field of solar photovoltaic cell materials. Background technique [0002] The solar cell modules currently produced are generally made of low-iron tempered glass, EVA film, single-chip solar cells with high conversion efficiency, EVA film, and a back film made of fluoroplastics and polyesters. Using reliable welding technology, high-vacuum heating lamination process and equipped with anti-corrosion aluminum alloy frame and watertight junction box, the solar cell module is prepared with reasonable structure, good UV aging resistance and wind resistance. [0003] As the upper packaging material of solar cell modules, tempered glass has good weather resistance, solvent resistance, heat resistance, transparency and water resistance. However, due to the fragility and heavy defects of ...
