Embodiment 1

[0069] A high barrier UV curable organic / inorganic compound consisting of the following components:

[0070]

[0071] The preparation method of the high barrier UV curing organic / inorganic compound is as follows:

[0072] Step 1: Prepare a planetary vacuum mixer, place each component in the compound in a planetary vacuum mixer, and stir at a temperature of 40°C to 50°C to obtain a high-barrier UV-curable organic / inorganic compound;

[0073] Step 2: Filter the high-barrier UV-curable organic / inorganic compound obtained in step 1 with a 1600-mesh nylon filter cloth into a syringe, then place the syringe in an oven, and heat and defoam at 40°C for 4 hours , to obtain a refined high-barrier UV-curable organic / inorganic compound.

Embodiment 2

[0075] A high barrier UV curable organic / inorganic composite consisting of the following components:

[0076]

[0077] Its preparation process is basically the same as that of Example 1, and will not be repeated here.

Embodiment 3

[0079] A high barrier UV curable organic / inorganic composite consisting of the following components:

Abstract

The invention discloses a high barrier UV curable organic / inorganic compound, a preparation method and application thereof. The high barrier UV curable organic / inorganic compound comprises the following components by weight: 30-50 parts of UV curable resin; 20-40 parts of modified lamellar nanofiller; 0.1-0.5 part of a photoinitiator; 20-45 parts of an active diluent; and 0.5-5 parts of an assistant. The high barrier UV curable organic / inorganic compound has low oxygen and water vapor permeability, and good thermal stability, can be directly prepared by one-step process, also adopts in-situ polymerization way, reduces the separation and purification of nanofiller and ionic liquid, and the process is simple, is easy to operate, and has strong practicability. The high barrier UV curable organic / inorganic compound can be used for preparation of high barrier composite coatings.

Description

technical field [0001] The invention relates to the field of organic / inorganic composite materials, in particular, the invention relates to a high-barrier UV-curable organic / inorganic composite and its preparation method and application. Background technique [0002] In recent years, the vigorous development of optoelectronic technology has made organic light-emitting components (OLED), quantum dot displays (QuantumDots), organic solar cells (OPV), flexible liquid crystal screens (flexible LCD), electronic paper (E-paper), etc. will be in the future. The market occupies a considerable market share. In displays, in order to meet the above-mentioned requirements of modern technology for electronic products, it has become a development trend of optoelectronic technology to replace traditional glass substrates with plastic substrates as optoelectronic element substrates. Plastic substrates can not only provide thinner and more flexible features, but also improve the shortcoming...
