Abstract

The invention discloses a fluorescent attapulgite clay and a preparation method thereof. The fluorescent attapulgite clay is prepared from, by weight, 80-100 parts of purified attapulgite clay, 20-36 parts of montmorillonite, 10-25 parts of fly ash, 5-10 parts of calcium silicate, 0.5-6 parts of hydroxypropyl methyl cellulose, 0.5-2 parts of rhodamine organic fluorescent pigment, 0.5-2 parts of eosin organic fluorescent pigment, 0.5-2 parts of thiazole orange organic fluorescent pigment, 0.5-2 parts of white fluorescent pigment, 0.5-2 parts of green fluorescent pigment, 0.5-2 parts of black fluorescent pigment and 1-8 parts of sodium dodecyl sulfate. The fluorescent attapulgite clay contains safe and non-toxic ingredients, is higher in fluorescence efficiency, the cost is lower, and the preparation method is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of attapulgite clay modification, in particular to fluorescent attapulgite clay and a preparation method thereof. Background technique [0002] Attapulgite clay, referred to as attapulgite, is widely used. Attapulgite clay mine is a block-like structure, and the color is off-white, blue gray, light yellow and light green. Greasy luster, light specific gravity, Mohs hardness 2-3, viscous and plastic when wet, small drying shrinkage, no cracks, strong water absorption, which can reach more than 150%, pH=8.5 or so. Pure attapulgite clay is white, and is widely used in chemical industry, paint, papermaking, detergent additives and other industries. Organic fluorescent pigments, also known as sunlight pigments, are compounds that absorb light energy and emit colored fluorescence under sunlight. Fluorescent paint absorbs sunlight energy during the day and stores it, and releases it at night to display special fl...
