Abstract
The invention relates to the technical field of heat insulation materials, and concretely relates to a preparation method of a high-strength and lightweight inorganic heat insulation mortar. The heat insulation mortar is prepared from 100-200 parts of ordinary Portland cement, 80-120 parts of pottery sand, 50-80 parts of silica fume, 30-50 parts of fly ash, 4-8 parts of re-dispersible latex powder, 2-5 parts of vitreous fibers, 1-3 parts of a surfactant, 1-3 parts of a foam stabilizer and 100-300 parts of water. The purpose of the invention is to provide the preparation method of the high-strength and lightweight inorganic heat insulation mortar with the advantages of convenient construction and good performances.
Description
Technical field
The present invention relates to the technical field of lagging material, specifically a kind of preparation method of high-strength light inorganic heat insulation mortar.
Background technology
Mortar is all a large amount of construction material all the time, the application of mortar has had the history of thousands of a century, the improvement of people to mortar all the time did not all stop, particularly in recent years, the appearance of various novel cpd, adds these various novel admixtures at traditional mortar, makes various novel composite mortar, very large improvement is carried out to traditional mortar, the economic benefit that to have made it play very large.Should be used for seeing with regard to existing market, inorganic heat insulation mortar is mainly used in exterior wall heat-preserving system.Lagging material in exterior wall heat-preserving system, expand to ZL rubber powder-polystyrene granule insulating mortar, extruded polystyrene board (XPS plate), stone(mine)cotton plate, urethane foam, multicellular glass etc. from original foaming (expansion) styrofoam (EPS plate), these lagging material overwhelming majority are all that organic materials is formed.These special organic materials thermal conductivitys are less, and starting material are cheap, be therefore widely adopted at present, but it still also exist some insoluble problems, as resistivity against fire, weathering resistance difference etc.Inorganic heat insulation mortar is a kind of newer lagging material, because not yet promulgate relevant national regulation and provincial standard, is incubated the enterprise of industry in implementation on probation at present primarily of part.Its unit weight of this Novel high-strength inorganic thermal-insulation mortar is little, and thermal and insulating performance is good, and bond closely with base material, water-intake rate is low, and sound-absorbing, fire prevention.
Summary of the invention
The object of the invention is the preparation method being to provide a kind of easy construction, high-strength light inorganic heat insulation mortar of good performance.
The technical solution used in the present invention is; a preparation method for high-strength light inorganic heat insulation mortar, by following raw material ratio: ordinary Portland cement 100-200 part, pottery sand 80-120 part, silicon ash 50-80 part, flyash 30-50 part, redispersable latex powder 4-8 part, vitreous fiber 2-5 part, tensio-active agent 1-3 part, suds-stabilizing agent 1-3 part, water 100-300 part.
Described preparation method adopts following step to obtain:
(1) ordinary Portland cement of said ratio, pottery sand, silicon ash, flyash, redispersable latex powder, vitreous fiber are uniformly mixed, the water adding fraction is stand-by after stirring and forming flow-like slurry;
(2) by the tensio-active agent of said ratio and suds-stabilizing agent, add the water doubly weighed according to the 20-30 of surfactant qualities, be stirred to bubble and formed rear stand-by in a large number;
(3) mixture that (1) and (2) obtains mixed and stirs, forming the thermal insulation mortar slip of good fluidity;
(4) the thermal insulation mortar slip casting (3) obtained or spurt in mould obtains.
Advantage of the present invention be cost lower, be easy to that construction, early stage microdilatancy, later stage linear shrinkage ratio are low, resistivity against fire and good endurance.
