Abstract
The invention belongs to energy-saving building materials field, relate to a kind of white glass bead modification heat-insulating masonry mortar and using method.This white heat-insulating masonry mortar by glass bead part replace aggregate, the mass fraction of each component is as follows: Binder Materials: 47.5～70.5%, glass bead: 10%～35%, aggregate: 3.6～20%, polymer dispersion powder: 0.3%～2%, hydroxypropyl methyl cellulose ether: 0.1%～0.3%, polypropylene fibre: 0.1%～1.2%, sepiolite fibre: 0.5%～1%, waterproofing agent: 0.1%～0.5%, mortar king: 0.08%～0.3%.Inorganic vitrified micro-bead heat preserving masonry mortar of the present invention has excellent workability and body of wall adhesive property is good, color is white; under meeting masonry mortar basic mechanical performance, endurance quality premise; effectively reduce mortar heat conductivity coefficient; having saved building energy consumption, application and development prospect is the most wide.
Description
Technical field
The present invention relates to building material field, be specifically related to a kind of white vitrified micro-bead heat preserving masonry mortar and system thereof
Preparation Method.
Background technology
The exterior wall heat-preserving system of China mainly uses organic insulation material.Although this kind of insulation material has good
Thermal and insulating performance, but weatherability is poor, volume stability is bad, the most fire-resistant, the most aging.Compared to organic guarantor
Adiabator, inorganic heat insulation mortar has plurality of advantages.Inorganic heat insulation mortar, especially kervit microbead insulated sand slurry,
It is by glass bead aggregate premixing in inorganic coagulation material and organic additive, the one-component insulation sand of formation
Slurry, has low cost, intensity height, insulation, fire prevention, the advantage such as weather-proof, can with surface layer anticracking grout,
Cross section processes mortar and assists material to form the heat insulation system of insulation, fireproof anti-cracking, waterproof, seepage control together.
Meanwhile, building external envelope structure is as the main position of architectural energy consumption, and its power consumption is at whole building energy consumption
In account for the largest percentage, therefore its power-saving technology becomes the emphasis of every country building structure energy saving research.Building
Exterior-wall heat insulation for alleviate indoor heat load, prevent peripheral structure be full of cracks and internal condensation be all favourable, with
Time can protect agent structure, reduce thermal stress, it is to avoid the generation of cold bridge phenomenon, there is obvious technological merit,
It it is the mainstream technology of Present Domestic External building peripheral structure insulation.
Therefore, kervit microbead insulated sand slurry has an above plurality of advantages, multilamellar and high-rise steel reinforced concrete structural construction,
Aerated concrete masonry body of wall and various brick-and-concrete buildings inner, external wall are plastered and have been obtained widely in heat insulating work
Application.But, for preventing kervit microbead insulated sand slurry shrinkage cracking, typically poly-third can be added in thermal insulation mortar
The anti-crack fibers such as alkene fiber or wood fibre.But polypropylene fibre smooth surface, surface can be low, mixes cement based
During material, there is fiber dispersion and can differ from and the problem of adhesive property difference between fibrous matrix.Though wood fibre
It is easier to mix homogeneously in kervit microbead insulated sand slurry system, but the shortcoming that there is slow setting.Meanwhile, glass bead
As masonry mortar, there is the problem that mechanical property is repelled mutually with thermal and insulating performance in thermal insulation mortar.
Summary of the invention
Goal of the invention: it is an object of the invention to provide a kind of white glass bead modification heat-insulating masonry mortar and make
By method, use as the masonry mortar in aerated concrete masonry and various brick-and-concrete buildings, can expire simultaneously
Foot mechanical property and thermal and insulating performance requirement.
Technical scheme: the present invention is directed to the drawbacks described above that current kervit microbead insulated sand slurry material exists, pass through glass
Change microballon part and replace medium sand, sepiolite fiber modified vitrification bead thermal insulation masonry mortar, optimized mix-proportion, system
Obtain high comprehensive performance, lower-cost vitrified micro-bead heat preserving masonry mortar.
Its component and proportioning (mass percent) be:
Described Binder Materials is 325 white portland cements.
Described glass bead bulk density is 100～120Kg/m3。
Described aggregate is medium sand.
Described polymer dispersion powder is ethylene-vinyl acetate polymer dispersion powder.
Selected hydroxypropyl methyl cellulose ether viscosity is between 100000Pa.s～150000Pa.s.
Described polypropylene fibre is 11mm chopped polypropylene fibre.
Selected sepiolite fibre is different length grating: 3-5mm 30%～40%；5-10mm 40%～50%；
10-15mm 20%～30%.
Described waterproofing agent is waterproofing agent of organosilicon.
Described mortar king is alkyl sulfonates mortar king.
Weigh each component in described each ratio, first cement, medium sand, sepiolite fibre and polypropylene fibre are mixed
Uniformly, then it is sequentially added into various additive and glass bead, after mix homogeneously, i.e. obtains described glass bead
Modified heat-insulating masonry mortar.
By heat insulating mortar powder and the water ratio of 1:0.45～1:0.6 in mass ratio during construction, stir 2 to 3 minutes,
Denseness controls 60～85mm, and standing 3 to 5 minutes can use.
Beneficial effect: following table is to detect glass bead modification heat-insulating masonry mortar end properties of the present invention
Result: (detection method: said components is prepared into vitrified micro-bead heat preserving masonry mortar dry powder by previous process adds
Suitable quantity of water, by standard-required molding sample.)
As can be seen from the above table, glass bead modification heat-insulating masonry mortar heat conductivity of the present invention is less than
0.30W/ (m K), resistance to compression and adhesion strength are high, linear shrinkage is little, and indices all meets JC 890 2001
" steam-pressing aero-concrete masonry mortar and decorative mortar " standard-required.
In sum, the above-mentioned beneficial effect having due to the present invention, so thermal-insulation energy-conservation effect is notable,
Pi of strength is superior, has saved building power consumption to a greater degree, and simple to operate during construction, and technology is wanted
Asking the highest, quality is easily controllable, it is simple to large-scale promotion application.
