Abstract

The invention belongs to the technical field of photics, and particularly relates to a water-borne photodiffusion coating, a water-borne photodiffusion film with low light and light loss as well as apreparation method and application of the water-borne photodiffusion film with low light and light loss. The water-borne photodiffusion coating is prepared from an appropriate amount of aqueous polyurethane emulsion (or dispersoid), organic and inorganic photodiffusion particles, a water-borne coating surface active additive, a water-borne coating film-forming additive and a solvent. The water-borne photodiffusion film with the low light and light loss is prepared from a water-borne photodiffusion coating and an adhesive agent, and the water-borne photodiffusion coating and the adhesive agentare adhered to a glass substrate of an LED lamp. According to the water-borne photodiffusion coating, the water-borne photodiffusion film with low light and light loss as well as the preparation method and the application of the water-borne photodiffusion film with the low light and light loss, a formula and a process of optimizing the water-borne photodiffusion coating are optimized, in particular to a key film-forming resin category and a matching use scheme of the key film-forming resin category, the categories and proportions of photodiffusion particles, the adhesive agent and other additives, and a production process of a film layer; therefore, the optimal optical matching among the film-forming resin, the photodiffusion particles and the substrate glass is realized, a peelable micro-scale optical film micro-structure with low light and light loss and high diffusion can be obtained, and the compatibility of high photopermeability of an LED illumination glass lamp is realized.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a water-based light-diffusing paint, a water-based low-light-loss light-diffusing film, a preparation method and an application. Background technique [0002] With the popularization of LED lighting, people have higher and higher requirements on the light efficiency, light diffusivity, and color rendering of LED lighting fixtures. However, the luminous efficiency and the light diffusivity are mutually restricted, and each other rises and falls. It is very difficult to achieve both high luminous efficiency and high diffusivity. For ordinary LED lighting fixtures, when the lamp bead, driver, and lampshade base material (usually glass or PC) are determined, the light diffusion film plays a decisive role in the light efficiency and light diffusivity, and the light transmittance of the light diffusion film determines the The light efficiency of LED lighting fixtures is h...
