preparation example 1

[0057] The modified resin is prepared from the following raw materials in mass percentage: 15% polytrifluorochloroethylene resin, 80% tetrafluoroethylene-hexafluoropropylene resin, and 5% plastic filling master batch. The plastic filling masterbatch is AY-T80 special masterbatch, the refractive index is 1.57, and the MFR is 10g / 10min, Foshan Anyi Nano Materials Co., Ltd. The polytrifluorochloroethylene resin is Japan Daikin PCTFEM-300P, the processing grade is extrusion grade, and the characteristic grade is transparent grade. Tetrafluoroethylene-hexafluoropropylene resin is Japan Daikin NP20, MFR is 4.5-8.5g / 10min.

[0058] The preparation method of modified resin comprises the following steps:

[0059] Step 1, polytrifluorochloroethylene resin is placed at 120°C, dried for 4 hours for later use, tetrafluoroethylene-hexafluoropropylene resin is placed at 140°C, and dried for 4 hours for later use;

[0060] In step 2, place 150g of polychlorotrifluoroethylene resin, 800g of ...

preparation example 2

Abstract

The invention relates to the technical field of solar cell front panel materials, in particular to a high-transmittance flexible composite front panel and a preparation method thereof. A high-light-transmittance flexible composite front plate comprises a flexible front plate body which is composed of a base material layer, a frosted layer and a water vapor blocking layer. The base material layer is a transparent modified ETFE film; the frosted layer is compounded on the surface, facing the air side, of the base material layer; the water vapor blocking layer is compounded on the surface, opposite to the air side, of the base material layer; the thickness of the flexible front plate main body is controlled to be 0.15 to 0.2 mm; and the light transmittance of the flexible front plate main body is 90-97%. The flexible solar cell composite front plate can be used for preparing a flexible solar cell, and popularization and application of the solar cell are facilitated. The LED light source module is light, thin, high in light transmittance and high temperature resistance and long in service life.

Description

technical field [0001] The present application relates to the technical field of solar cell front plate materials, in particular to a highly light-transmitting flexible composite front plate and a preparation method thereof. Background technique [0002] With the country's emphasis on environmental protection, the utilization and development of new energy has become a popular research and development direction after the 21st century. As a clean energy source, solar energy has attracted the attention of scholars and researchers from all over the world. Solar panels can convert solar energy into electrical energy for utilization, which can alleviate the problem of social power supply shortage and reduce dependence on fossil fuel power generation. [0003] A solar cell panel in the related art mainly includes a solar cell front plate-glass surface layer, an EVA sealing layer, a solar cell sheet, an EVA sealing layer and a solar cell back film, and the solar cell sheet is seale...
