Problems solved by technology

However, since its luminous coating is composed of metal sulfides, its main disadvantages are poor chemical stability, easy decomposition, and short luminous time (according to its test results: 20 parts of luminescent materials made of ZnS-Cu or CaS-Bi, mixed with ethylene - 100 parts of copolymer of acrylic acid or ethylene methacrylic acid, the prepared powder coating, the luminescence lasts up to 25 minutes), so it is difficult to meet the needs of industrial production and life

Abstract

A thermosetting luminescent powder paint is prepared from fluorescent material, special resin, pigmenta and filler. Its advantages are high luminescent stability and adhesion, durable luminescence, and no pollution.

Description

[0001] The present invention is a divisional application of Application No. 97100853.1 "Thermosetting Luminous Powder Coating and Its Manufacturing Method" filed on March 17, 1997. Technical field [0002] The invention relates to a thermosetting luminescent powder coating and a manufacturing method thereof. It belongs to a solid powder composition composed of a luminous material and a matching material for decorating and coating metal products or heat-resistant non-metallic luminous paint showing luminous light. Background technique [0003] At present, most of the luminescent coatings are luminescent materials, organic solvents, such as: polymer paint or composite resin and pigments and fillers composed of solvent-based luminescent coatings, for example: China "Invention Patent Application Publication" published a report on January 5, 1994 The name is luminous paint, the publication number is CN1080302A, and a luminous paint was published on March 30, 1994, and the publication n...
