Abstract

The invention belongs to the technical field of solid waste treatment, specifically relates to a geopolymer prepared based on printing and dyeing sludge and a thermal insulation, sound insulation and humidity control board, and further discloses a preparation method thereof. The geopolymer prepared based on the printing and dyeing sludge of the present invention uses the modified printing and dyeing sludge after photocatalytic degradation to directly cooperate with fly ash, adjusts the suitable silicon-aluminum ratio of the system by adding silicon source materials, and adds organic matter to obtain A lightweight geopolymer. The heat-preserving, sound-insulating and humidity-regulating board of the present invention is prepared in a conventional manner by using the geopolymer as a raw material. The board has good sound-absorbing, heat-insulating and humidity-regulating performances, and can be widely used in the field of functional building decoration.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, specifically relates to a geopolymer prepared based on printing and dyeing sludge and a thermal insulation, sound insulation and humidity control board, and further discloses a preparation method thereof. Background technique [0002] Sludge usually refers to the product of sewage treatment, which is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content (up to 99%), high organic content, easy to rot and smell, and fine particles, small specific gravity, mostly in a colloidal liquid state. Sludge is a thick material between liquid and solid, which can be transported by pump, but it is usually difficult to separate solid and liquid by sedimentation. There are many types of sludge, mainly including sludge produced by enterprises, such as electroplating sludge, p...
