Problems solved by technology

But the disadvantage is that the light and heat stability is poor, it is difficult to process and shape, and the polymer matrix material is easy to process, impact resistance, corrosion resistance and light weight, etc., research on rare earth organic complexes, compound rare earth complexes into polymer matrix to make Rare earth polymer materials can improve certain properties of materials, such as mechanical properties and optical properties, to achieve functional complementarity and performance optimization
[0003] Ultraviolet light curing technology has the characteristics of wide applicability, high efficiency, energy saving and environmental protection, and has been widely used in production and life. With the global restrictions on environmental pollution emissions and the improvement of people's environmental awareness, traditional solvent-based coatings have become very Difficult to adapt to environmental protection requirements, it is bound to be replaced by UV-curable coatings

Abstract

The invention discloses an ultraviolet cured rare earth polymer material and a preparation method thereof. The ultraviolet cured rare earth polymer material includes the following components in percentage by weight: 1%-20% of rare earth and acrylic acid complex, 40%-60% of urethane acrylate, 30-50% of active diluent, 1%-10% of photoinitiator and the balance of auxiliaries. The ultraviolet cured rare earth polymer material has the advantages that the rare earth and acrylic acid complex and the matrix resin are subjected to polymerization reaction, thus being good in consistency; the rare earth and acrylic acid complex modified resin is good fluorescence property and wide in ultraviolet absorption peak that the range stretch across the ultraviolet and near-ultraviolet areas; as the coating prepared by the above materials has the characteristics of being quick in photocuring speed, good in film property and friendly to environment; the film can be used for ultraviolet cured paint and luminous paint.
