Method for preparing cement floor color paste and cement curing enhancer from dye residual paste and application

Abstract

The invention discloses a method for preparing cement floor color paste and a cement curing enhancer from dye residual paste and application. The method comprises the following steps: preparing mother liquor from the dye residual paste; mixing 70-85 parts by weight of mother liquor, 2-6 parts by weight of polyether polyol, 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, evenly stirring for 60-120 minutes to obtain the cement floor color paste and the cement curing enhancer, sealing, and storing. If the specific gravity value of the dye residual paste is 1.15-1.17, the dye residual paste is used as mother liquor; and if the specific gravity value is lower than 1.15-1.17, following steps are executed: extracting polyacrylamide according to 0.5-2% of the weight of the dye residual paste, adding a proper amount of dilution water to prepare polyacrylamide into a solution, adding the dye residual paste into the solution, stirring, precipitating, removing the upper part of the liquid similar with water, and taking the liquid as a mother liquor when the specific gravity value is 1.15-1.17. The method has the beneficial effects that the method is simple, processing is convenient, dye emission is effectively solved, and buildings are beautified.

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 en...
