Abstract

The invention relates to an adhesive of polymer reinforced aerated concrete light brick and a method for preparing thereof, which relates to a technical field of construction materials. The adhesive consists essentially of cement, fly ash, dry sand, water retaining agent, re-dispersible polymer emulsion powder and water reducing agent. Weight ratio of the cement, fly ash, dry sand, water retaining agent, re-dispersible polymer emulsion powder and water reducing agent is 300 to 310: 90 to 95: 600: 2: 20: 2 to 3. The invention is characterized by light dry density, low thermal conductivity, good weathering resistance stability and high fire resistance rating. When the adhesive is smeared on external wall of reinforced concrete, concrete hollow block and multihole clay brick, phenomena such as voiding, cracking, hollow protuberance, etc. do not occur, which avoids leakage, wind penetration and spalling of the wall and can reduce the cement consumption.

Description

Polymer reinforced aerated concrete light-brick adhesives and compound method thereof
Technical field
The present invention relates to building material technical field.
Background technology
Growing along with energy saving building is the aerated concrete light-brick of main material production with flyash.Though aerated concrete light-brick has light weight, insulation, sound insulation, energy-conservation characteristics, but because the shrinking percentage and the water-intake rate of this type of material are big than traditional material at present, when adopting common masonry mortar and motar, there is certain defective in base material combines the boundary with mortar adhesive property, build layer after the feasible construction by laying bricks or stones and occur empty, cracking, the phenomenons such as being prone to hollowing of plastering easily.
Summary of the invention
The object of the invention is to invent a kind of aerated concrete light-brick that bonds that is used to, and occurs the polymer reinforced aerated concrete light-brick adhesives of phenomenons such as cavity, cracking, hollowing after avoiding constructing.
The present invention mainly is made up of cement, flyash, dry sand, water-holding agent, redispersible polymer latex powder and water reducer, and the mass ratio of cement, flyash, dry sand, water-holding agent, redispersible polymer latex powder and water reducer is 300～310: 90～95: 600: 2: 20: 2～3.
Redispersible dose of polymer emulsion powder is a kind ofly can form stable dispersion liquid again after adding water-dispersion, and has the polymer emulsion rubber powder of original synthetic polymer emulsion performance, adopts spray-dired method preparation usually.After redispersible dose of polymer emulsion powder adds water and form dispersion liquid, after moisture evaporation, can form and have high degree of flexibility and close-burning polymeric film, can improve cohesive force and force of cohesion, reduce weak property modulus, increase folding strength and flexural strength.Simultaneously, redispersible dose of polymer emulsion powder has stability in storage preferably again, protects to make product deposit adhesion under normal condition, keeps mobile well, convenient production.Redispersible dose of polymer emulsion powder and cement mixing are used, and can improve the cohesiveness of the present invention and thin layer plaster.
The present invention has that dry density is light, thermal conductivity is low, weather-proof good stability, characteristics that fire resistance rating is high.Through test, except that other performance satisfied the JC890-2001 index, the tackiness agent dry density was not more than 1800kg/m 3, delamination degree is not more than 20mm, and be 3～5 hours time of coagulation, and ultimate compression strength reaches 5.0MPa, and cohesive strength is 0.2MPa, shrinkage value is less than 1.1mm/m.Spread upon outside Steel Concrete, concrete hollow block, the porous clay brick wall, phenomenons such as cavity, cracking, hollowing can not occur, avoid the body of wall seepage, let in air, peel off, also can reduce cement consumption.
Water-holding agent of the present invention is a methyl cellulose ether.
In gas concrete tackiness agent and thin layer plaster, methyl cellulose ether plays water conservation, thickening, improves effects such as workability.Good water-retentivity has guarantees that mortar can not reduce owing to dusting, a powder and the intensity that lack of water, hydrated cementitious not exclusively cause.Thickening effectiveness uses the structural strength of wet mortar to strengthen greatly, and in addition, methyl cellulose ether also can obviously improve the wet viscosity of mortar, and various base materials are all had good viscosity, to improve the last wall performance of wet mortar, cuts the waste.
In addition, second compound method that purpose is to invent above-mentioned polymer reinforced aerated concrete light-brick adhesives of the present invention.
Earlier with cement, flyash, water-holding agent, redispersible polymer latex powder and water reducer by 300～310: 90～95: 2: 20: 2～3 quality than uniform mixing after, add 600 parts of dry sand uniform mixing again.
With cement, flyash, water-holding agent, redispersible polymer latex powder and water reducer, add dry sand again and mix earlier, purpose is to make the product stirring more even.
Embodiment
One, tackiness agent formulation operations example:
Earlier with cement, flyash, methyl cellulose ether, redispersible polymer latex powder and water reducer by 300～310: 90～95: 2: 20: 2～3 quality than uniform mixing after, add 600 parts of dry sand uniform mixing again, make polymer reinforced aerated concrete light-brick adhesives.
Two, use:
Tackiness agent after the preparation duration of service must not be above 2 hours.
When being used for the level bonding, should be with building with the shop, the full rate of mortar should be not less than 90%, and gray seam thickness is 10mm～13mm.
When being used for vertical mortar joint, with the inside and outside interim clamping plate cementation of fissures, stitching wide is 15mm～18mm.
Three, effect:
1, the through engineering approaches of dry binder is used.
2, the various detrimentally affects that produce too greatly because of the novel wall material water-intake rate are avoided in the supporting use of novel wall material.
