preparation example 1

[0041] The preparation of carbon nanotube surface hybrid nano-alumina comprises the following steps:

[0042] Step 1: at room temperature, add 0.02mol of 2-ethyl-4-methylimidazole 2E4MI, 0.01mol of silver acetate AgAc in 400mL of dichloromethane, magnetic stirring, rotating speed 240r / min, magnetic stirring time control In 1-2 hours, until the AgAc particles completely disappear, clear and transparent Ag(2E4MI) is obtained 2 Ac complex solution;

[0043] Step 2: In Ag(2E4MI) 2 Add 0.5g of CNTs and 0.5g of PVP to the Ac complex solution, and use ultrasonic dispersion for 3 hours. The power of the ultrasonic generator is 1200W, and the frequency is 20kHz. Add 50 grams of α-alumina, and continue ultrasonic dispersion for 0.5 hours to obtain a dispersion .

[0044] Step 3: The dispersion liquid obtained in step 2 is subjected to vacuum distillation treatment, and after removing the dichloromethane in the dispersion liquid, the solid matter is subjected to high-temperature sinte...

preparation example 2

[0050] The difference between Preparation Example 2 and Preparation Example 1 is that the modified mixed filler is composed of nano-alumina, t-zirconia, and T-ZnO whiskers. The preparation method of the modified mixed filler is to put 78g of nano-alumina, 3.5g of zirconia powder with a D50 of 120nm and 2g of T-ZnO whiskers into a high-speed dispersion kettle, and mix and disperse at 600rpm for 15min to obtain a modified mixed filler. filler.

preparation example 3

[0052] The difference between Preparation Example 3 and Preparation Example 1 is that the modified mixed filler is composed of nano-alumina and t-zirconia. The preparation method of the modified mixed filler is to first put 78g of nano-alumina and 3.5g of zirconia powder with a D50 of 120nm into a high-speed dispersion kettle, and mix and disperse at 600rpm for 15min to obtain the modified mixed filler.

Abstract

The invention relates to the technical field of solar packaging films, in particular to a flexible packaging antibacterial composite film and a preparation method thereof. A flexible packaging antibacterial composite film comprises a core layer EVA film and weather-proof modified EVA films integrally formed on the upper surface and the lower surface of the core layer EVA film through a three-layer co-extrusion technology, and the core layer EVA film is mainly prepared from EVA resin; the weather-resistant modified EVA film is prepared from the following raw materials in percentage by mass: 0.6%-1.5% of a coupling agent, 0.4%-0.8% of a cross-linking agent TBEC, 0.6%-0.8% of an assistant cross-linking agent TAIC, 0.2%-0.5% of an antioxidant composition, 0.3%-0.5% of an anti-ultraviolet agent mixture, 6%-10% of modified mixed filler, 0.8%-1.2% of an antibacterial agent and the balance of EVA resin. The coating is good in elasticity, high in flexibility and transparency, good in adhesive property, good in corrosion resistance and weather resistance, good in aging resistance, good in ultraviolet resistance and good in insulating property.

Description

technical field [0001] The present application relates to the technical field of solar energy encapsulation films, in particular to a flexible encapsulation antibacterial composite film and a preparation method thereof. Background technique [0002] With the rapid development of society and the rapid increase of population, the global energy shortage and environmental pollution problems have become increasingly prominent, and it is particularly important to find clean and environmentally friendly new energy. As the most common clean energy, solar energy has become a bright spot in the world's new energy field. Solar photovoltaic cells convert light energy into electrical energy, enabling the utilization of solar energy. The solar photovoltaic cell in the related art includes a front plate, an encapsulation material, a silicon cell, an encapsulation material, and a back plate. Silicon cells are mainly divided into monocrystalline silicon solar cells, polycrystalline silicon...
