PMMA RESIN MATERIAL, OPTICAL PRODUCT, AND PREPARATION METHOD FOR PMMA RESIN MATERIAL AND APPLICATION THEREOF IN PREPARATION OF OPTICAL PRODUCT

The present invention relates to a PMMA resin material, an optical product, and a preparation method for the PMMA resin material and an application thereof in preparation of the optical product. The PMMA resin material provided by the present invention comprises polymethyl methacrylate, an antioxidant, a dispersant, and a transmittance modifier. In the PMMA resin material provided by the present invention, the PMMA resin material obtained by compounding the polymethyl methacrylate and the specific transmittance modifier has a relatively good neutral filtering effect within a wave band range of 425-1025 nm, has the advantages of easy processing and low cost, and can be widely applied to preparation of optical products, such as an optical filter, a camera or a digital camera. La présente invention concerne un matériau de résine PMMA, un produit optique, et un procédé de préparation du matériau de résine PMMA et une application associée dans la préparation du produit optique.
