Technical Field

The invention relates to the technical field of light absorption materials, in particular to a double-layer and multi-surface light absorption material for chemical reagent storage.

Background

The light absorbing material is used for absorbing light rays, namely the light rays irradiate on objects, do not transmit outside illumination, do not generate mapping and massive flare spots and reflection, and diffuse and reflect partial light rays after absorbing the light rays, so that a regular light and shade level is maintained.

Chemical reagents are relatively standard substances for chemical research and component analysis, are important conditions for technological progress, are widely used for synthesis, separation, qualitative and quantitative analysis of substances, can be said to be eyes of chemists, and are not separated from chemical reagents in daily work of factories, schools, hospitals and research institutes.

The chemical reagent is influenced by external factors such as temperature, light irradiation, air, moisture and the like in the processes of storage, transportation and sale, and physical and chemical changes such as deliquescence, mycin, discoloration, polymerization, oxidation, volatilization, sublimation, decomposition and the like are easy to occur, so that the chemical reagent cannot be used due to failure, and therefore reasonable packaging, proper storage conditions and transportation modes are adopted to ensure that the chemical reagent does not deteriorate in the processes of storage, transportation and sale.

In particular, many chemical reagents are very easy to volatilize and deteriorate under strong light, so in order to prevent the reagents from being radiated by light, brown glass bottles are adopted, the reagents are externally wrapped by black paper and stored in a dark room or a shading reagent cabinet, and the reagents which are suitable for carrying out photochemical reaction, such as amines, phenols, aldehydes and the like, are stored in a dark place; actually most reagents all need to be deposited in the dark place, just require differently to the dark place, and the brown reagent bottle is used mostly to current chemical reagent storage, can absorb most visible light and then reach the light-proof effect.

However, in the prior art, there are two general ways in the preparation process, one is to spray light absorption thin film layers on both sides of a glass substrate, but the light absorption thin film layers may fall off with the lapse of storage time, and the other is to dope a light absorption material in the glass substrate, but the light absorption compactness is difficult to meet the requirement, and the light leakage phenomenon is easy to occur for the storage of chemical reagents with high light-shielding requirements.
