Method and application of dye residue for preparing cement floor color paste and cement curing enhancer

Abstract

The invention discloses a method and application for preparing cement floor color paste and cement solidification enhancer from dye residue. The method comprises the following steps: using dye residue to prepare mother liquor; mixing 70-85 parts by weight of mother liquor, polyether polyol 2~6 parts by weight, 2~8 parts by weight of triethanolamine, 6~10 parts by weight of lithium silicate, 3~10 parts by weight of urea and 3~10 parts by weight of diethylene glycol are mixed together and stirred evenly, and the stirring time is After 60 to 120 minutes, the cement floor color paste and cement curing enhancer are obtained, which are sealed and stored. If the specific gravity value of the dye residue is 1.15-1.17, it is used as mother liquor; if the specific gravity is lower than 1.15-1.17, the following steps are included: extracting polyacrylamide by 0.5-2% of the weight of the dye residue, adding an appropriate amount Dilution water dissolves polyacrylamide into a solution, the solution is added to the dye residue and stirred, then precipitated, and the upper part of the liquid close to water is removed, and when the specific gravity reaches 1.15~1.17, it is used as the mother liquor. The invention has the beneficial effects of simple method, convenient processing, effectively solving dye discharge and beautifying buildings.

Description

technical field [0001] The invention relates to a method and application for preparing cement floor color paste and cement solidification enhancer from dye residue. Background technique [0002] Textile printing and dyeing enterprises are major polluters. The dye uptake rate of dyes used in dyeing processing is generally only 50% to 98%, and about 2% to 50% of dyes become printing and dyeing wastewater, resulting in increased environmental protection costs for enterprises and difficulty in sewage treatment. There are many kinds of printing and dyeing dyes, the largest types are direct dyes, reactive dyes, disperse dyes, acid dyes, vat dyes, azo dyes, cationic dyes, etc., but they are basically environmentally friendly dyes. Solidification, reconciliation has a very good use in the building materials industry, but as waste discharge to produce high-concentration wastewater and secondary pollution discharge of incineration waste gas, enterprises are under huge pressure on envi...
