Fireproof lightweight composite thermal insulation mortar and its preparation method

Abstract

The invention discloses a fireproof lightweight composite thermal insulation mortar. The mortar is prepared from the following raw materials, by weight, 5-8 parts of resin type re-dispersible latex powder, 1-3 parts of a wood fiber, 3-6 parts of a hydroxypropyl methyl fiber, 3-7 parts of a polypropylene short fiber, 80-120 parts of heavy calcium powder, 80-120 parts of slaked lime, 80-120 parts of coal ash, 600-800 parts of cement, 300-500 parts of a glass bead, 1-2.5 parts of a high-efficiency water reducer, 1-3 parts of a thixotroping lubricant, 3-5 pars of a concrete waterproof agent and 0.1-0.4 parts of an air entraining agent. The preparation method of the mortar comprises the following steps: adding the raw materials according to a certain order, and fully and uniformly mixing under normal temperature, normal pressure and a stirring speed of 10r / 100min. The mortar has the following advantages: a defect that the maintenances of common wall thermal insulation materials cannot be realized by themselves is solved, problems comprising cracking, hollowing, shedding and the like appearing after construction are solved because the needed balance of water absorption and water discharge is automatically reached, and small construction difficulty at normal temperature and according with energy saving and environmental protection requirements are realized because of no use of complicated operations comprising grid cloth use or the like.

Description

technical field [0001] The invention relates to a material used for walls, in particular to a fireproof lightweight composite thermal insulation mortar and a preparation method thereof. Background technique [0002] At present, the general wall insulation materials mainly use rubber powder polyurethane and cement as the coagulation material, and the aggregates mainly use silicon-calcium board, polystyrene board, extruded board organic materials or traditional inorganic materials. The existing general wall insulation materials There are the following disadvantages: no fire protection, low compressive strength, large deformation coefficient, poor safety and stability, easy to crack, low thermal insulation coefficient, no energy saving, easy to cause environmental pollution, difficult construction, and high cost. It does not meet the requirements of fire prevention, energy saving, environmental protection, easy construction and low cost. Contents of the invention [0003] Th...
