Abstract

A night luminous PET resin comprises the following components, by weight, 100 parts of PET, 1-2 parts of ethylene bis-stearamide, 2-8 parts of a night luminous coloring agent, and 5 parts of a compatilizer. The night luminous coloring agent is composed of, by weight, 10 parts of europium-doped strontium aluminate luminous powder and 1 part of phthalocyanine green. The night luminous coloring agent is prepared with the green pigment and the europium-doped strontium aluminate luminous powder pigment, so that the night luminous PET resin has durable coloring time and is not liable to hydrolyze and discolor.

Description

technical field [0001] The invention relates to a 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. Luminous sulfide is ...
