Abstract

The invention provides a coal water slurry dispersant made by using modified molasses and a preparation method of the coal water slurry dispersant, and relates to the technical field of coal water slurry dispersants. The coal water slurry dispersant is prepared from the following raw material components in parts by weight: 30-80 parts of the molasses, 5-25 parts of 32% liquid sodium hydroxide, 5-10 parts of 27% hydrogen peroxide, 350-500 parts of deionized water, 0.5-1.5 parts of 3-thiohydracrylic acid, 200-335 parts of monomer TPEG 200-600, 1-2 parts of sodium formaldehyde sulfoxylate, 20-35parts of methacrylic acid and 5-10 parts of hydroxyl ethyl ester. According to the coal water slurry dispersant, molasses modification is used for industrial production to avoid resource waste duringdirect treatment of the molasses, pollution of waste discharge to the environment during fermentation treatment is avoided, and application of the modified molasses to the new field is realized.

Description

technical field [0001] The invention relates to the technical field of coal water slurry dispersant, in particular to a coal water slurry dispersant made from modified molasses and a preparation method thereof. Background technique [0002] Molasses is a by-product in the process of making sugar from sugarcane, beet, citrus, corn, etc., so it is generally divided into sucrose molasses, beet molasses, citrus molasses, corn molasses, etc. according to the source. Molasses contains a large amount of sugar, protein, minerals, vitamins, cellulose, amines and other rich material components. The proportion of each component is slightly different due to different types of molasses. At present, the total domestic supply of molasses is about 4 million tons per year, which is mainly used for fermentation to produce alcohol, yeast, and direct treatment for the production of feed. At the same time, some modified molasses is used for industrial production, such as cement water reduction a...
