Problems solved by technology

[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 deficiencies: 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, high cost
Does not meet the requirements of fire prevention, energy saving, environmental protection, easy construction and low cost

Embodiment 1

[0009] Example 1: First add 1kg of wood fiber, 6Kg of hydroxypropyl methyl fiber, and 3kg of polypropylene short fiber into the powder mixer, start the mixer at normal temperature and pressure, and stir for 3-5min at a speed of 50r / min, then add 600Kg of cement , fly ash 120Kg, heavy calcium powder 80Kg, slaked lime 75Kg, stir for 25-30min, after mixing evenly, add vitrified microbeads 300Kg, resin type redispersible rubber powder 5.5Kg, thixotropic lubricant 1Kg, high-efficiency water reducing Waterproofing agent 1Kg, concrete waterproofing agent 3Kg, air-entraining agent 0.1Kg, continue to stir for 30-35min, fully mix evenly, and obtain the powdery product.

Embodiment 2

[0010] Embodiment 2: The dosage of each component and the stirring speed are as follows, and all the other operations are the same as in Embodiment 1.

[0011]

[0012] The thermal insulation mortar of the present invention is through testing, and main index is as follows:

[0013] Appearance: gray powder; bulk density: 341Kg / m 3 ; Compressive strength: 1.05Mpa; thermal conductivity: 0.071W / (m.k); linear shrinkage: 0.20%; compressive shear bond strength: 166Kpa; combustion performance level: A. How to use: Add water and stir to a proper consistency under normal temperature and pressure, and use it on the wall.

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...
