Abstract

The present invention relates to the preparation process of nanometer modified UV cured resin paint. The preparation process includes preparing nanometer oxide through sol-gel process, controlling calcining temperature and adding PVA or gelatin to control the particle size of the nanometer oxide in 20-40 nm; measuring the particle size, crystal form, etc. of the nanometer oxide; surface modifying the nanometer oxide with siloxane or titanate coupling agent; mixing pre-polymerizing glue, active monomer, photosensitive agent, initiator and solvent to form the UV cured resin paint pre-polymer; and adding and ultrasonically dispersing the nanometer oxide to obtain the nanometer modified UV cured resin paint. The nanometer modified UV cured resin paint of the present invention has prolonged curing period, complete curing, homogeneous coating thickness, high coating hardness, high heat resistance, and high wear resistance.

Description

A technical field [0001] The invention relates to a preparation method of a material surface coating, in particular to a preparation method of a nano-modified ultraviolet curing resin coating. Two background technology [0002] Coating is a widely used fine chemical, involving various parts of daily life, national economy and national defense. It develops very rapidly, and its varieties have expanded from general-purpose coatings that only have decorative and protective functions to various properties that can change the surface of the coated object. special coatings. UV-curable coating is a new type of coating, which has developed rapidly in recent years due to its advantages of energy saving, environmental protection, and fast processing speed. Nanomaterials and nanotechnology are new disciplines and research hotspots in recent years. When the particle size reaches the nanometer level (1-100nm), it has quantum size effect, small size effect, surface effect and macroscopi...
