Accumulated luminous plastic product and its preparation method

Abstract

The present invention relates to one kind of energy accumulating luminous plastic product and its production process. The energy accumulating luminous plastic includes plastic resin and conventional assistants in the amount not more than 95 % and energy accumulating luminous powder not less than 5 %. When the energy accumulating luminous plastic is used in producing luminous safety helmet, it contains plastic resin and conventional assistants in 75-95 wt% and energy accumulating luminous powder in 5-25 wt%. The plastic resin may be ABS, PC, PS or POM resin; the conventional assistants includes at least one of antiager, flame retarder, defoaming agent and dispersant; and the energy accumulating luminous powder is RE exciting alkali earth metal compound. The energy accumulating luminous plastic product is produced through mixing the said components and injection molding.

Description

technical field [0001] The present invention relates to an energy-storage optical-vision plastic product and a preparation method thereof, in particular to an energy-storage optical-vision plastic product based on a rare earth element-activated alkaline earth metal compound as a matrix and a preparation method thereof, which is used for night-vision luminescent markers such as Night vision road signs, night vision work helmets, etc. Background technique [0002] People who work at night, ride bicycles at night, or work in civil air defense projects, mines, etc., are most concerned about safety, and what they need most is night vision luminous signs that are easy to identify. So people have developed night vision reflective sheets and reflective powder for night vision signs, but there must be a safety effect under the condition of light irradiation, and the night vision working environment cannot be improved. Chinese patent (patent application No. 001077384) "Double Light D...

Problems solved by technology

Because the preparation method is processed twice, it has a destructive effect on the molecular structure of the plastic itself, and the products made are prone to aging, reduced luminous intensity, shortened use mission, and reduced safety performance. The alkaline earth aluminate luminescent powder produced by Dalian High-tech Commercial Application Research Institute has a high luminous intensity in a short period of time, but the light intensity decays quickly and cannot maintain the light intensity for a certain period of time, especially not suitable for night operations. helmet
