Problems solved by technology

However, the practice of multiple coating or deposition of organic and inorganic layers greatly increases the complexity of the process and the production cost
In addition, the physical and chemical properties of ordinary organic layer materials and inorganic layer materials are quite different, which will cause insufficient interfacial bonding force, and easily cause some defects during the preparation of the barrier layer or during the long-term use of the device, thereby reducing the water-oxygen barrier performance.

Abstract

The invention discloses an organosilicone / inorganic silicon hybridization blocking coating composition and a preparation method and an application thereof. The organosilicone / inorganic silicon hybridization blocking coating composition comprises the following components according to the parts by weight: 30-70 parts of multi-functional cage-type polysilsesquioxane, 25-65 parts of an organic siliconresin, 0-15 parts of an organosilicone-modified (methyl) acrylic resin, 0.2-5 parts of a photoinitiator, and 5-15 parts of an assistant. The organosilicone / inorganic silicon hybridization blocking coating composition has the higher water-oxygen blocking property to a common organic layer material, excellent resistance to yellowing, good glossiness, and better interface bonding force with an inorganic layer, so that a blocking layer can achieve the water-oxygen blocking property of a common multi-layer blocking layer material under the condition of reducing the number of layers to three layers. The blocking coating can be used for greatly reducing the production time and cost of a plastic base material blocking layer, and improving the reliability of the blocking layer.

Description

technical field [0001] The invention relates to the field of functional polymers, in particular, the invention relates to a preparation method and application of an organic silicon / inorganic silicon hybrid barrier coating composition. 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 shortcomings o...
