Abstract

The invention discloses thermal insulation mortar utilizing modified papermaking sludge particles. The thermal insulation mortar is characterized by being prepared from the following raw materials inparts by mass: 100 parts of sulphoaluminate cement, 10 to 30 parts of polymer emulsion, 10 to 30 parts of the modified papermaking sludge particles, 3 to 5 parts of polystyrene particles, 7 to 9 partsof vitrified micro-beads, 0.4 to 0.6 part of sodium polyacrylate, 0.2 to 0.4 part of an air entraining agent, 0.5 to 0.7 part of a polycarboxylic acid water reducer and a proper amount of water. According to the thermal insulation mortar utilizing the modified papermaking sludge particles, disclosed by the invention, advantages of papermaking sludge components is utilized; after being decomposedat high temperature, the papermaking sludge particles are ground; then the papermaking sludge particles are sufficiently dispersed and modified through a sodium polyacrylate solution and the polymer emulsion; wastes including the papermaking sludge particles and the like can be cyclically utilized so that the cost is reduced; properties including the strength and water absorption rate of the thermal insulation mortar also can be improved.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to the preparation of thermal insulation mortar. Background technique [0002] As the core component of building energy saving, the technology of external wall insulation system has been highly valued all over the world. Energy-saving building insulation systems can not only greatly reduce building energy consumption, but also help protect energy resource consumption, reduce pollution, and improve indoor comfort. As the most important link in the thermal insulation system, the thermal insulation mortar needs to be improved urgently. Papermaking sludge is mainly used as industrial solid waste for landfill treatment or as waste piled up for treatment. However, these treatment methods all take up a large amount of land, and landfilling and stacking can easily cause soil pollution. The invention develops the function of papermaking sludge, grinds papermaking slud...
