Technical Field

The invention relates to the field of luminous paint on the surface of a metal material, in particular to energy-storage luminous powder paint and a production construction method.

Background

The energy-storage luminous powder coating is not strange, but the market prefers to select an energy-storage oil coating and an energy-storage water-based coating which are not suitable for being used as energy-storage products, and also prefers to use the energy-storage powder coating, mainly because of the following reasons:

1. the energy storage powder coating has uneven dispersion of the luminescent raw materials, which leads to serious differentiation of the whole appearance.

2. The product effect of over blowing and steam, the luminous time is long for the theory, and the difference between the practical application and the product propaganda is very large.

3. The brightness of the light energy released by the product is low, and the afterglow brightness and the afterglow duration cannot be ensured.

4. The product is easy to corrode or cover by the outside, so that the normal energy storage and light emitting cannot be realized.

The main factor to these reasons is the blind development by the developer without assessing the potential risk of developing the initial product: the raw materials of the product are not screened and the material parameters are not limited, the problems to be avoided by the production process and the formula synthesis process matched with the product are not set aiming at the particularity of the product, or the characteristics which should be possessed by the product or even the defects which appear in the construction process are not estimated or set in advance, so that the current product can only be researched and developed successfully on the surface and cannot form a real commodity, or the product only stays at the initial stage of the commodity and cannot be applied to the middle and high end. Accidental contamination is also a factor directly affecting the energy storage and light emission of the product.

How to match the raw materials, the formula, the production process, the construction process and the spraying process. How to modify can promote energy storage to give out light, but does not have negative effects or slight influence, but does not influence the main performance of the product, it is the topic that we need to discuss again;
