Abstract

A preparation method of night luminous PET resin includes the following steps: (A) mixing and stirring 10 parts of a europium-doped strontium aluminate luminous powder with phthalocyanine green powder at 90-140 r / min at normal temperature for 10 min, and drying the mixture to prepare a night luminous coloring agent; (B) feeding PET, ethylene bis-stearamide and polypropylene-grafted maleic anhydride into a stirrer, and feeding the night luminous coloring agent into the stirrer, and stirring and mixing all the components in the stirrer at 60 r / min at normal temperature for 20 min to prepare a final mixture; and C) feeding the final mixture into a twin-screw extruder, performing extrusion at the process temperature of 290 DEG C at the main engine rotational speed of 280 r / min to form strips, and air-drying and cutting the strips into granules to obtain the sterilizing polyester resin. The parts, which are contacted with the final mixture, in the twin-screw extruder are all made from aluminum, so that with the aluminum for producing the contacting parts, a problem that strontium ion becomes black when being contacted with iron is avoided indirectly.

Description

technical field [0001] The invention relates to a preparation method of luminous PET resin. Background technique [0002] Luminous plastic material is a plastic material that produces afterglow at night after being illuminated during the day. [0003] At present, the luminous materials commonly used at home and abroad are mainly luminous powders made of sulfide ZnS, SrS or CaS as the matrix. SrS and CaS materials are easy to decompose due to moisture, which brings difficulties to wide application, while the afterglow time of ZnS-based luminous materials is only 1 to 3 hours, which is limited in practical use. [0004] The luminous plastics in the prior art are mainly injection-molded after direct stirring and mixing of strontium-containing luminous powder and plastic particles. This method is prone to the following problems in actual production: 1. The luminous powder is easy to react with the iron wall of the extruder and blacken, resulting in black air in the plastic. 2...
