Environmentally friendly anti-myopia ink and preparation method

Abstract

An environmentally friendly anti-myopia ink, comprising the following components in parts by weight: 45-50 parts of epoxy acrylate, 0.5-1 parts of maleic anhydride, 10-15 parts of tannic acid, 18-25 parts of natural rubber latex, 1.5-3 parts of bio-based plasticizer, 15-18 parts of plant-derived yellow pigment, 1-3 parts of blue light absorber, 5-8 parts of silane-modified silica, 0.5-1.5 parts of polyvinyl alcohol and 3-5 parts of pullulan. The invention utilizes various safe and environmentally friendly bio-based materials to construct a multi-layered synergistic protective system. Gardenia yellow and curcumin core-shell pigments serve as the primary protection, covering entire blue light spectrum; silane-modified silica diffuse reflection and pullulan act as the secondary protection, refracting and matching to scatter any residual blue light. The flexibility of tannic acid and epoxy acrylate combined with elasticity of natural rubber form the tertiary protection, reducing the compensatory tension in the optic nerve caused by page-turning vibrations.
