Embodiment 1

[0013] First prepare the modified light aggregate, add an appropriate amount of water to the organosilicon waterproofing agent and mix the light aggregate with a drum mixer to make the surface wet, the humidity should be about 40%, and then add portland cement to stir. Cover the surface with a layer of cement 0.4mm, and form this light aggregate after solidification.

[0014] Then prepare the gel material: 8 parts of ordinary Portland cement, 1.6 parts of coal ash, 0.2 part of latex powder, 0.08 part of hydroxypropyl methylcellulose, 0.02 part of polypropylene fiber, and 0.1 part of wood fiber.

[0015] Finally, prepare thermal insulation mortar: mix the above-mentioned modified light aggregate in Kg unit by weight: the above-mentioned gel material by volume in L unit = 1:6 to prepare modified inorganic thermal insulation mortar.

[0016]

Embodiment 2

[0018] First prepare the modified light aggregate, add an appropriate amount of water to the organosilicon waterproofing agent and mix the light aggregate with a drum mixer to make the surface wet. The humidity is about 35%, and then put in portland cement and stir. Cover the surface with a layer of cement 0.3mm, and form this light aggregate after solidification.

[0019] Then prepare the gel material: 5 parts of ordinary Portland cement, 1 part of coal ash, 0.1 part of latex powder, 0.05 part of hydroxypropyl methylcellulose, 0.01 part of polypropylene fiber, and 0.05 part of wood fiber.

[0020] Finally, prepare thermal insulation mortar: mix the above-mentioned modified light aggregate in Kg unit by weight: the above gel material by volume in L unit = 1:4 to prepare modified inorganic thermal insulation mortar.

[0021]

Embodiment 3

[0023] First prepare the modified light aggregate, add an appropriate amount of water to the organosilicon waterproofing agent and mix the light aggregate with a drum mixer to make the surface wet, the humidity should be about 40%, and then add portland cement to stir. Cover the surface with a layer of cement 0.5mm, and form this light aggregate after solidification.

[0024] Then prepare the gel material: 10 parts of ordinary Portland cement, 2 parts of coal ash, 0.3 part of latex powder, 0.1 part of hydroxypropyl methylcellulose, 0.03 part of polypropylene fiber, and 0.2 part of wood fiber are mixed.

[0025] Finally, prepare thermal insulation mortar: mix the above-mentioned modified light aggregate by weight in Kg unit: the above-mentioned gel material by volume in L unit = 1:8 to prepare modified inorganic thermal insulation mortar.

Abstract

The invention relates to a modified inorganic thermal-insulation mortar which comprises the following components in parts by mass: 5-10 parts of Portland cement, 1-2 parts of coal ash, 0.1-0.3 part of latex powder, 0.05-0.1 part of hydroxypropyl methylcellulose, 0.01-0.03 part of polypropylene fiber and 0.05-0.2 part of wood fiber. The ratio of the weight value (Kg) of the sum of raw materials to the volume value (L) of the modified light-weight aggregate is 1:4-1:8. A waterproofing agent is utilized to coat a Portland cement layer on the surface of the thermal-insulation light-weight aggregate to obtain the thermal-insulation aggregate, and a plurality of cementing materials are added to obtain the thermal-insulation material. The thermal-insulation mortar is convenient and simple to prepare, improves the properties of the thermal-insulation aggregate, and enhances the strength and hydrophobicity.

Description

technical field [0001] The invention relates to a mortar, in particular to a modified inorganic thermal insulation mortar with high strength and hydrophobic performance. Background technique [0002] Light aggregate is mainly used to prepare light aggregate concrete, thermal insulation mortar and refractory concrete, etc. Traditional natural light aggregates have low strength and high water absorption, and the insulation materials prepared from them also have the same disadvantages. The high water absorption rate of thermal insulation materials seriously affects its thermal insulation effect and safety performance. Contents of the invention [0003] Aiming at the shortcomings of using natural light aggregates to prepare thermal insulation materials in the prior art, the present invention provides a modified inorganic thermal insulation mortar with high strength and high hydrophobicity, which is convenient and simple to prepare, can effectively improve the performance...
