Abstract

The invention discloses a sunshade net for an organic light-converting agent containing rare earth luminescent ions and a preparation method thereof. The sunshade net is prepared from 40 to 45 parts of polyethylene, 5 to 10 parts of polylactic acid, 1 to 2 parts of a cross-linking agent, 3 to 5 parts of a foaming agent and 1 to 5 parts of a rare earth organic light-converting agent. The rare earthorganic light-converting agent is prepared from 5 to 10 parts by weight of a polyurethane prepolymer, 0.4 to 2 parts by weight of an epoxy resin, 2 to 5 parts by weight of ethyl cellulose, 1 to 2 parts by weight of a urea-formaldehyde resin, 2 to 3 parts by weight of gelatin and 5 parts by weight of an EuCl3 aqueous solution with a concentration of 0.1 mol / L. The rare earth organic light-converting agent is crosslinked through the gelatin system so that the rare earth organic light-converting agent is firmly bonded to the system. The component in the gelatin system is used as a ligand of therare earth element so that the light conversion efficiency is guaranteed and the rare earth element maintains stable light conversion efficiency for 10 months or more. The sunshade net is suitable forcultivation in greenhouses.

Description

technical field [0001] The invention relates to a preparation method of a sunshade net, in particular to a preparation method of a sunshade net with an organic light conversion agent containing rare earth luminescent ions. Background technique [0002] At present, in the field of plant cultivation, "light fertilizer" is a new development field, such as the use of light energy conversion film to increase the photosynthesis of plants. It can be seen that in addition to the function of ordinary sunshade nets, the sunshade net can specifically change the radiation spectrum to improve the quality of crops. The photosynthetic characteristics, and increase the scattered light to improve the lighting conditions of crops, thereby regulating the growth of plants. In addition, because insects have a tendency to avoid specific colors, color shade nets theoretically also have a certain insect-proof function. [0003] Rare earth organic light conversion agent is a kind of organic complexe...
