Description

A kind of cement based polymer heat preserving dry powder mortar and using method
Technical field
The present invention relates to a kind of cement based polymer heat preserving dry powder mortar and using method of building material field.
Background technology
At present, the heat insulation system that China's buildings mainly adopts is an external wall heat insulation system, wherein, use more be glue powder polyphenyl granule exterior wall outer heat preservation system and EPS (XPS) plate thin plastering outer heat preservation system, above-mentioned traditional external wall heat insulation system all is a coat of plaster, thermal insulation layer, protective layer is that use is handled in the multilayer layering, its construction technology typically uses energy-saving materials for wall and carries out building wall → wall plastering → body of wall processing (interface processing) → thermal insulation layer construction → heat preservation protective layer construction (anticracking grout and net defence) → insulation examination → architectural surface construction, there is the construction technology complexity in the above-mentioned technology, operation is many, the shortcoming of long construction period, above-mentioned material for external thermal insulation system of external wall exists economy bad, the shortcoming that cost value is higher.
Summary of the invention
Given this, the technical problem to be solved in the present invention provides the cement based polymer heat preserving dry powder mortar and the using method of building material field, adopt direct one deck to handle, solve the construction technology complexity that exists in traditional construction technology, operation is many, the technical problem that long construction period and economy are bad, cost value is higher.
In order to solve the problems of the technologies described above, the present invention, a kind of cement based polymer heat preserving dry powder mortar contains cement, light-weight aggregate, flyash, quartz sand, and component proportioning by weight is as follows:
Cement 30-40 part
Light-weight aggregate 40-50 part
Flyash 8-10 part
Quartz sand 10-20 part
Further, limiting the cement that uses is 42.5 type ordinary Portland cements, makes thermal insulation mortar have good physicals.
Further, limit the light-weight aggregate that uses and be fly ash float and glass bead.Adopt the fly ash float and the glass bead of light weight, stable physical property, steady bubble technology and starting material rational proportion make product have better thermal property through foaming.
Further, limit cement based polymer heat preserving dry powder mortar, can also include one or more compositions in polymer dispersion powder and water-holding agent, hydrophober, polypropylene fibre, wood fibre, the mortar plasticizer in addition again, the shared parts by weight of its total amount are less than or equal to 12 parts.
Add polymer dispersion powder and can form crosslinked film with the cement cementitious material reaction, can clog, block, refinement part hacking pore, tensile strength, folding strength, bending strength, the cohesive strength of giving cement based polymer heat preserving mortar excellence handled in modification by polymkeric substance, have good sticking power and shock resistance, improve its snappiness simultaneously, reduce linear shrinkage; The water retention capacity of cement based polymer heat preserving mortar is better than ordinary mortar, and mixing of water-holding agent improves bleeding and segregation phenomenon, uses on gas concrete and porous material and has avoided the cracking, the hollowing phenomenon that cause because of dehydration etc.; Hydrophober is cement based hydrophobic type material, form the silicone resin three-dimensional structure net of remarkable hydrophobic function by reaction, external enwergy is resisted erosion and the infiltration of outside moisture to mortar inside, but do not shut the passage of mortar water evaporation simultaneously again, reach not only hydrophobic but also gas-pervious function; Improve admixtures such as adding polypropylene fibre on the basis of its snappiness and internal structure at polymkeric substance and increase its resistance to cleavage, stop cracking, hollowing phenomenon that a variety of causes causes; Adding wood fibre is in order to improve the workability of mortar, to have cracking resistance and water retention simultaneously; Adding mortar plasticizer is in order to improve the mortar workability.
The using method of a kind of cement based polymer heat preserving dry powder mortar of the present invention is: each component is mixed thoroughly according to the combination of Different Weight umber in limited range, water is using on-the-spot the interpolation, constitute I type, II type, III type cement based polymer heat preserving mortar respectively, during use, use III type cement based polymer heat preserving mortar to build by laying bricks or stones; Use II type cement based polymer heat preserving mortar to wipe one's face; Using I type cement based polymer heat preserving mortar to carry out heat bridge handles; The proportioning of the water of described I type, II type, III type cement based polymer heat preserving mortar and the weight of cement based polymer heat preserving dry powder mortar is 1:0.36-0.42; 1:0.46-0.52; 1:0.48-0.55.
Adopt the cement based polymer heat preserving dry powder mortar of technique scheme, because cement, light-weight aggregate, flyash, quartz sand are combined into mortar product, adopt factory's premix technology, in use add entry by proportioning and stir and can use, the heat preservation slurry constructing operation that stirs is with traditional motar, carries out maintenance after finishing by design thickness, when finished product is checked and accepted, both satisfied the requirement of wall plastering layer, satisfied thermal property again, had following beneficial effect as thermal insulation layer:
1) can be one building, wipe one's face, be incubated collection by laying bricks or stones, simplify procurement of materials, management;
2) scene adds water and stirs and can use, and has saved material usage;
3) alleviate the deadweight of buildings, reduce building foundation and structural load;
4) simplify working procedure and auxiliary facility thereof, reduced construction man-hour and labour intensity;
5) safe, long-acting, avoid repairing and time limit replacing problem.
