Abstract

The invention discloses a preparation method of a long-acting moisture-resistant luminous plastic master batch, comprising the following operation steps: (1) uniformly mixing strontium carbonate, strontium carbonate, calcium carbonate, aluminium oxide, europium oxide and promethium oxide, and performing sintering treatment, so as to obtain fluorescent powder; (2) adding lanthanum chloride and erbium chloride into water, uniformly mixing and stirring, further adding naphthenic acid therein, and then heating the mixture and holding the temperature, so as to prepare naphthenic acid rare earth; (3) uniformly mixing the fluorescent powder with the naphthenic acid rare earth, so as to obtain modified fluorescent powder; (4) adding polypropylene resin, the modified fluorescent powder, a dispersing agent and an antioxidant to a high-speed mixer, uniformly mixing, and performing extrusion pelleting by adopting a twin-screw extruder, so as to prepare the long-acting moisture-resistant luminous plastic master batch. The plastic master batch prepared according to the invention is high in luminescent intensity, takes effect for a long time, and still has excellent luminescent performance especially in an environment with a relatively high humidity.

Description

technical field [0001] The invention belongs to the technical field of plastic preparation, and in particular relates to a preparation method of a long-acting moisture-resistant luminescent plastic masterbatch. Background technique [0002] Plastic masterbatch is a new type of plastic molding processing aid developed in the 1980s. It is made by adding plastic additives in excess of the usual amount to the carrier resin. Therefore, when molding plastic products, masterbatch can be added directly. The use of plastic masterbatch can simplify the production process, reduce dust flying and wear on equipment, save raw materials, make the mixing of raw materials convenient and uniform in quality, thereby improving production efficiency and product performance indicators. Therefore, plastic masterbatch has played a great role in promoting the rapid development of the plastics industry. Scholars at home and abroad have done a lot of research work on plastic masterbatch processing tec...
