preparation example Construction
[0045] The present invention also provides a method for preparing the surface coating of the reflective film, which includes steps S10-S40.
[0046] Step S10: Mixing the carbon nanotubes and isopropanol to prepare a mixture A.
[0047] Optionally, the carbon nanotubes are added as powdered carbon nanotubes.
[0048] Step S20: mix mixture A, water and ammonia water, stir, add silica sol and tetraethyl orthosilicate, and prepare mixture B.
[0049] In some examples, in step S20, water and ammonia water are sequentially added to the mixture A, stirred at 1000r / min for 10min, silica sol and tetraethyl orthosilicate are added, and stirred at 1500r / min for 1h-2h.
[0050]Step S30: Mix the mixture B, the fluorosilane and the antistatic agent, and stir for 24h to 72h to prepare a raw material solution for the surface coating of the reflective film.
[0051] Step S40: coating the raw material solution on the substrate, and drying.
[0052] The surface coating of the reflective film ...
specific Embodiment
[0070] Here, the reflective film surface coating, reflective film and preparation method thereof according to the present invention are exemplified, but the present invention is not limited to the following examples.
Embodiment 1
[0072] Example 1
[0073] 1) Ultrasonic dispersion of 0.2 parts of powdered carbon nanotubes in 50 parts of isopropanol solution to obtain mixture A;
[0074] 2) Add 4 parts of deionized water and 1 part of ammonia water (30%) to mixture A in turn, stir at 1000r / min for 10min, add 0.1 part of silica sol, 0.3 part of tetraethyl orthosilicate, and stir at 1500r / min 1h to obtain mixture B;
[0075] 3) Add 0.5 parts of heptadecafluorodecyltrimethoxysilane and 1 part of alkylsulfonate dropwise to mixture B, and stir for 24 hours to obtain a surface coating solution for the reflective film.
[0076] 4) Use a corona treatment machine to process the surface of the reflective film to make the surface have a rough surface. The output frequency of the corona treatment machine is 15kHz, and the electrode gap is 1.3mm.
