Abstract

The invention belongs to the technical field of adhesives and light-converting materials, and particularly relates to an ultraviolet light-curing adhesive with a light-converting function and a preparation method thereof. The adhesive is a blended solution comprising monomer A, monomer B, light conversion agent, photoinitiator, diluent, defoamer and antioxidant; the monomer A is a mercapto-containing carboxylate compound or Trimethylolpropane, the monomer B is an allyl compound or a triacrylate compound. The UV-curable adhesive of the invention is cured to form a light-converting film, wherein the light-converting agent has good compatibility with the matrix resin, can be uniformly dispersed in the resin liquid, has good mechanical properties and light-converting properties, and has high light transmittance. , strong adhesion to plastic or glass, good water resistance, simple preparation process, easy reaction conditions, easy large-scale production, can well convert ultraviolet light into red light that is beneficial to plant growth, and can be applied to Agricultural planting field.

Description

technical field [0001] The invention belongs to the technical field of adhesives and light conversion materials, and in particular relates to an ultraviolet light curing adhesive with light conversion function and a preparation method thereof. Background technique [0002] In agricultural production, in addition to using chemical fertilizers to promote plant growth, physical factors such as sunlight in nature can also affect plant growth. Not all wavelengths of light in sunlight are beneficial to the development of plants. Only under the light of a specific wavelength that is most suitable for plant growth can plants grow rapidly and improve their quality. Photoecological studies have shown that blue-violet light at 400-480 nm and red-orange light at 630-680 nm are beneficial to plant photosynthesis, while ultraviolet light below 400 nm is harmful to crops. Therefore, the plastic light-converting film that converts ultraviolet light that cannot be used by plant stems and le...
