Embodiment 1-5 and comparative example 1-3

[0035] According to the proportions of the components shown in Table 1, the optical adhesive, the cross-linking curing agent, the anti-ultraviolet absorber and the blue light absorber were uniformly mixed to prepare an anti-ultraviolet and blue-light-absorbing optical adhesive composition;

[0036] Then after defoaming, it is coated on a heavy-release polyester film (YT-1008, manufactured by Guangzhou Nansha Huazhuo Chemical Co., Ltd.), baked in an oven to make the dry thickness 50um after the solvent is evaporated, and finally coated with a light-release polyester film compound (YT-4106, manufactured by Guangzhou Nansha Chemical Co., Ltd.), to obtain an optical adhesive sheet with anti-ultraviolet and blue light absorption.

[0037] Wherein, in Example 1, the optical adhesive is a solvent-based acrylate polymer adhesive resin, the crosslinking curing agent is an isocyanate trimer, the anti-ultraviolet absorber is UV-531, and the blue light absorber is an inorganic rare earth f...

Embodiment 2

[0038] In Example 2, the optical adhesive is a rubber-modified acrylate resin, the cross-linking curing agent is epoxy glycidyl ether, the anti-ultraviolet absorber is UV-327, and the blue light absorber is an organically synthesized orange-yellow absorbing material;

[0039] In the embodiment 3-5, the optical adhesive is a solvent-based acrylate polymer adhesive resin, the crosslinking curing agent is an isocyanate trimer, the anti-ultraviolet absorber is UV-9, and the blue light absorber is an inorganic rare earth fluorescent material; The diluted monomer is SR-395NS or SR351NS.

Embodiment 6

[0041] The components shown in Table 1 were uniformly mixed in proportion to prepare an anti-ultraviolet and blue light-absorbing optical adhesive composition;

[0042] Then after defoaming, it is coated on heavy-release polyester film (YT-1008, manufactured by Guangzhou Nansha Huazhuo Chemical Co., Ltd.), and then compounded with light-release polyester film (YT-4106, manufactured by Guangzhou Nansha Chemical Co., Ltd.) , and finally accumulated energy of 1000mj / cm by ultraviolet radiation 2 Finally, the dry thickness is 50um to obtain an optical adhesive sheet that is anti-ultraviolet and can absorb blue light.

[0043] Among them, the optical adhesive is solvent-free acrylate polymer adhesive resin, the cross-linking curing agent is isocyanate trimer, the anti-ultraviolet absorber is UV-531, the blue light absorber is inorganic rare earth fluorescent material, and the reactive diluent monomer is SR238NS.

Abstract

The invention discloses an ultraviolet-resistant blue-light-absorbable optical bonding agent composition and an optical bonding piece with the bonding agent layer. The optical bonding agent composition comprises 100 parts of optical bonding agent, 1-10 parts of crosslinking curing agent, 0.01-5 parts of ultraviolet-resistant absorbent and 0.001-1 part of blue light absorbent. The ultraviolet-resistant blue-light-absorbable optical bonding agent composition and bonding piece have high light transmittance, low haze and favorable ultraviolet (with the wavelength of 300-380nm or so) shielding capacity, can absorb harmful blue light (400-470nm) to the human body in the visible portion, can be widely used as a current screen display device lamination body or intelligent screen protective film or other products capable of resisting ultraviolet and blue light (such as sunglasses, polaroids and the like), and greatly lower the injuries of ultraviolet and blue light to the skin and eyes of the human body.

Description

technical field [0001] The invention relates to an optical adhesive composition and an adhesive sheet, in particular to an optical adhesive composition and an optical adhesive sheet that are anti-ultraviolet and can absorb blue light. Background technique [0002] Optical adhesive sheet is a commonly used material for bonding and fixing transparent materials. It is used for transparent substrate materials (such as glass, acrylic, polycarbonate, etc.), polyester films (such as PET\TAC\PP, etc.). With the development of technology, the adhesive sheet has been widely used in the field of life, such as sunshade glasses, sunshield window glass, touch screen and so on. However, in the display life, especially the current display screen, many electromagnetic waves, ultraviolet rays and near-infrared rays will be generated. If you stare at the screen for a long time, the emitted ultraviolet and blue light will seriously damage human health. [0003] Studies have shown that long-ter...
