Synthetic example 1

[0026] 1. Add all monomers acrylic acid, n-butyl acrylate, acrylonitrile, initiator benzoyl peroxide, and butyl into a 500ml four-necked flask, and stir to form an emulsion.

[0027] 2. Transfer 2 / 3 of the emulsion to a constant pressure dropping funnel for titration.

[0028] 3. The temperature of the water bath is raised to 82°C, and the reaction is slowly added dropwise with a constant pressure dropping funnel, and the temperature is kept at 82±2.0°C to prevent the reaction from being violent; the dropwise addition is completed in 3 hours.

[0029] 4. Turn off the heating after dripping, stir and cool down to normal temperature, and the synthesis is completed.

[0030] The specific addition amount is shown in Table 1 below:

Synthetic example 2

[0035] Complete according to steps 1-4 of Synthesis Example 1, and the specific addition amount is shown in Table 2 below.

[0036] Table 2

[0037] acrylic acid 3.00g n-butyl acrylate 35g Acrylonitrile 11.00g Benzoyl peroxide 0.02g Butyl ester 50.98g total 100.00g

[0038] 5. In the synthesized acrylic resin, add 10 parts of transparent nano powder for every 100 parts.

Embodiment 1

[0047] Coat the adhesive of Synthesis Example 1 on the optical PET with a thickness of 20 microns, and at a maximum pressing temperature of 80°C, laminate a 35-micron VLP copper foil, bake and cure in an oven, and the maximum curing temperature is 160°C.

[0048] The main characteristics of the finished product are shown in Table 4

Abstract

The invention discloses a transparent flexible nano composite base material which is characterized in comprising an optical PET film; the two sides of the optical PET inner film are covered with VLP copper foils through acrylic acid adhesives; the acrylic acid adhesive is prepared by synthesizing acrylic acid, n-butyl acrylate, acrylonitrile and butyl ester, the addition ratio of acrylic acid is 1-10%, the addition ratio of n-butyl acrylate is 20-50%, and the addition ratio of acrylonitrile is 10-30%; the thickness of the optical PET inner film ranges from 12 micrometers to 188 micrometers, and the light transmittance of the optical PET inner film is not lower than 92%. The thickness of the VLP copper foil ranges from 12 micrometers to 70 micrometers. The invention also discloses a preparation method and application of the transparent flexible nano composite base material. The transparent flexible nano composite base material prepared by the invention effectively controls the influenceof yellowing while ensuring high light transmittance in long-term use.

Description

technical field [0001] The invention relates to the field of nanomaterial preparation, in particular to a transparent and flexible nanocomposite base material and its preparation method and application. Background technique [0002] LED flexible materials usually have white backlight or yellow backlight. The light effect of this two-color flexible LED material cannot pass through the back, and can only illuminate 180° from one side. [0003] The use of high-transmittance flexible nano-materials does not block the LED lighting decoration. It is especially suitable for high-end outdoor scene applications, and can give full play to the 360° viewing effect of LEDs. The current application market is large-scale outdoor publicity, advertisements, and glass window strips on the exterior walls of buildings. Decorated with LED lights. [0004] However, the current highly light-transmitting flexible materials are prone to yellowing during long-term use, and the long-term use effect i...
