Abstract

The invention provides a solar spectrum conversion resin and preparation and application methods of the solar spectrum inversion resin. The solar spectrum inversion resin is characterized in that a light conversion agent subjected to surface modification is mixed with solid PVB resin and molten; the melt is casted and extruded through an extruder to prepare a light conversion PVB resin film; or the light conversion agent is directly dispersed into liquid light curing glass resin to obtain light curing conversion glass resin, wherein the light conversion agent is one or two of a green-to-red light conversion agent, a red and blue double light conversion agent, a purple-to-blue light conversion agent and a purple-to-red light conversion agent; the particle size ranges from 0.01 to 5.0 microns; 0.05 to 5.0% by mass of light conversion agent is added to the resin; a surface modifier is prepared from one or two of methylsilicone oil, KH-570 and stearic acid, and 4 to 40% by mass of the surface modifier is added; the two light conversion resins can be used for preparing light conversion laminated glass which has all-day light conversion function and can absorb near ultraviolet or/ and green light and emit blue light and/ or red light; the light conversion laminated glass can be applied to a glass greenhouse to increase the photosynthesis of the crops as well as promoting the growth of plants; a purple/ green-to-red light conversion PVC resin film can be applied to solar cell packaging, and therefore, the photovoltaic efficiency of a solar cell can be increased.

Description

technical field [0001] The invention belongs to the technical field of optical functional resins, specifically solar spectrum conversion polymer resins, referred to as light conversion resins, and relates to a solid light conversion PVB resin film and a liquid light curing light conversion glass resin, and their preparation methods and applications. Background technique [0002] In the solar spectrum vertically incident on the ground, the main components are concentrated in the range of 400-720 nm, and the green light component accounts for about 50% of the total energy of solar radiation. Plant photosynthesis is the most common way to utilize solar energy. Converting the green light and near-ultraviolet light components in sunlight into blue light and red light that can be absorbed by plant chlorophyll can greatly improve the utilization rate of solar energy by plants and increase crop production and income. Reasonably improving the utilization rate of solar energy has be...
