The preparation method of above-mentioned adiabatic adhesive mortar is as follows:
(1) first cement, flyash, densification powder, ether of cellulose, wood fibre are mixed and make dry mash;
(2) add glass bead to the dry mash in step (1), further mix the dry mixing material that makes adiabatic adhesive mortar;
(3) dry mixing material step (2) being made is placed in stirrer, adds water and stirs 2min, suspends and stirs 3min, then continue to stir 2min, makes the wet-mixing material of adiabatic bonding mortar.
The present invention is using cement and flyash as gelling material, and glass bead is as light skeletal, under the modifying function of the components such as densification powder, ether of cellulose and wood fibre, prepares that a kind of dry density is little, thermal conductivity is low and the reliable adiabatic adhesive mortar of intensity.Compared with current common masonry mortar, the present invention shows following features:
1. adopt glass bead to replace sand in common masonry mortar as aggregate, glass bead has surperficial vitreous sealing, inner porous air cavity configuration, can significantly reduce the dry density of adhesive mortar, improves the heat insulating effect of building mortar joint by laying bricks or stones.
2. as water-keeping thickening material, ether of cellulose can significantly improve the workability of adhesive mortar, and ether of cellulose has bleed effect simultaneously, contributes to reduce the dry density of adhesive mortar, further improves the heat insulating effect of building mortar joint by laying bricks or stones.
Advantage of the present invention is as follows:
1. the adiabatic adhesive mortar dry density of the present invention is little, thermal conductivity is low and intensity is reliable.
2. while building by laying bricks or stones for haydite aerated concrete block, build mortar joint by laying bricks or stones close with building block thermal conductivity, eliminated " cold bridge " phenomenon of body of wall, be conducive to improve the heat insulating effect of body of wall.
3. preparation technology is simple.
4. take full advantage of flyash industrial waste, there is the profit excellent environmental protection effect such as useless, energy-conservation and good economic benefit.
