Abstract

The invention discloses a modified photo-hardening resin composition for high-wear-resistance / high-toughness / high-hardness nanometer materials, which consists of silane-modified non-photosensitive inorganic nanometer particles, silane-modified polypropylene (methyl) oxide acrylate prepolymers, resin prepolymer mixture, mixed active monomers, a photo initiator, a thermal initiator and assistants. The resin composition has the advantages of high hardness, high wear resistance, high toughness, high yellowing resistance, high temperature and humidity resistance, wide applicability and the like.

Description

Technical field: [0001] The present invention relates to a resin composition. Background technique: [0002] The current coating type photohardening resin coating is used as the surface of the mobile phone control panel based on polyethylene terephthalate (PET) / polycarbonate (PC) / polymethyl methacrylate (PMMA) film The molding material is gradually accepted by more and more mobile phone manufacturers. Its main feature is that it can be light-cured according to the design requirements of the mobile phone control panel. It can achieve the required high wear resistance and high hardness on the surface through the adjustment of the light-hardening resin composition. Or high flexibility, good feel and other surface features, and even the surface effects of different colors can be modulated according to design needs. Although there are a small number of domestic companies developing this type of material, many properties such as wear resistance, pencil hardness, flexibility, ...
