Kaolin dyeing sludge geopolymer material and preparation method therefor
The invention relates to a kaolin dyeing sludge geopolymer material which comprises a cementing material and a compound activator in a mass ratio of 1:(0.4-1.0); the cementing material is a blended calcined product of kaolin and dried dyeing sludge, wherein the mass ratio of the dried dyeing sludge and kaolin is 1:(3-7); the dried dyeing sludge is the dyeing sludge which is obtained through quenching and high-temperature tempering with lime and ferric salts and drying; the compound activator is prepared from sodium water glass and sodium hydroxide, and the modulus of the compound activator is 1-2. The invention provides an effective path to solve the problems in recycling and utilization of incremental components of the dyeing sludge after chemical quenching and high-temperature tempering and drying, so that the dyeing sludge becomes the geopolymer material rather than a simple filling material, and heavy metal pollutants are sealed.
