Abstract

The invention discloses a preparation method for a photoluminescent hydrogel composite material. The preparation method comprises: preparing an emulsion by foam plastic (waste foam plastic recommended); carrying out surface coating on a long-afterglow luminescent material by the emulsion to form micro-emulsion balls; and then adding a hydrophilic macro-molecular monomer to initiate grafted polymerization reaction on the surfaces of the micro-emulsion balls of the monomer under the condition of a crosslinking agent and an initiator to prepare the hydrogel composite material. The photoluminescent hydrogel prepared by the method disclosed by the invention not only has water adsorption and water-retaining property of the hydrogel, but also has a photoluminescent function, is of certain appreciation, and plays roles of indicating at night and marking.

Description

technical field [0001] The invention belongs to the technical field of functional polymer composite materials, and relates to a method for recycling waste foam plastics, in particular to a method for preparing photoluminescence hydrogel composite materials by using waste foam plastics, the hydrogel The composite material has high water absorption and water retention properties, and has certain ornamental, indicating and marking functions. Background technique [0002] Superabsorbent resin material is one of the main components of various agricultural and forestry water-retaining agents, and it is also a new soilless culture substrate that replaces soil for planting plants. With the rapid process of modernization, the rapid expansion of population, the global greenhouse effect and the drought problems, therefore, since the discovery of super absorbent resin in the 1960s, and its application in soil improvement, water retention and drought resistance, etc., super absorbent No...
