Description

A kind of manufacturing method of luminous wax product

technical field

The present invention relates to a method for manufacturing a luminescent wax product, in particular to a method for manufacturing a wax product, which is to make a luminescent wax artwork or Related Products.

technical background

The phenomenon that a substance absorbs energy and emits light is called luminescence. Due to the difference in electron energy transition and spin after the substance is illuminated, luminescence can be divided into two types: fluorescence and phosphorescence. The constituent units of luminescent materials include the host lattice (Host Lattice) mainly composed of inorganic compounds and the activation center (Activator) of transition metal ions. Sometimes another component is added to the lattice to increase the luminous brightness and efficiency. Luminescent materials are mainly used in optoelectronic and information-related industries that mainly use electroluminescence, such as well-known fluorescent lamps, LEDs, and screen backlights. Among them, those with high luminous efficiency and in the visible light region are called phosphors.

Luminescent phosphors (commonly known as phosphors) are excited by sunlight (or other external energy equivalent to ultraviolet rays), and after the excitation is stopped, the afterglow (after a few minutes to several hours) is still visible to the naked eye. Glow), the conventional long-acting phosphor is mainly Cu or Co-doped zinc sulfide, which can emit green light with a wavelength of 530nm after being irradiated by ultraviolet rays. The light of this wavelength is the most sensitive area of the human eye, so it is often used in To make dark display materials (such as used for time display of clocks), and to increase its phosphorescence time, radioactive ³ H or ¹⁴⁷ Pm is often added; for environmental protection considerations, recently, Murayama Yoshimoto of Japan’s Essential Specialty Chemicals Co., Ltd. Yan et al. disclosed (China Taiwan Invention Patent No. 076319) that a compound based on MAl ₂ O ₄ (M is Ca, Sr, Ba) was added by simultaneously adding 0.001 mol% or more and 10 mol% or less of europium (Eu) It is an activator and at least one element (selected from cerium, praseodymium, neodymium, samarium, yttrium, dysprosium, erbium, ytterbium, lutetium, manganese, tin, bismuth) below the same molar range is an activator. After the new phosphor is irradiated with 200-450nm ultraviolet and visible light at room temperature, its photopersistence (afterglow time) is longer than that of traditional zinc sulfide (ZnS), and this new compound is not radioactive, and it is not easy to dissolve in the air. The effect of moisture, in addition to being applicable to indoor displays, can also be used outdoors.

Also, since the discovery of MAl ₂ O ₄ -based phosphors, a variety of practical products have been developed, such as emergency exit signs at night, safety clothing for pedestrians at night, toys, etc., but these products are all plastic products. The traditional method is to heat and mix MAl ₂ O ₄ phosphors with plastic particles and then inject them into moldings. These products are limited by the characteristics of the plastic itself and cannot be made into more delicate artworks.

Therefore, how to propose a novel luminescent wax product manufacturing method for the above problems can not only improve the traditional application of luminescent materials to wax-related artworks, but also obtain plastic arts during the day and luminescence at night. Characteristic wax products have long been a matter that users have longed for and the inventor intends to solve, and the inventor is based on many years of research, development, and sales experience in wax related products, thinking and improving ideas , Poor his personal professional knowledge, after many researches and designs, and special discussions, he finally worked out an improved method of manufacturing wax products with luminescence, which can solve the above problems.
