Abstract
The invention discloses an anti-cracking binder special for a light partition wall board. The anti-cracking binder is prepared by evenly mixing a limestone mechanism sand sieve bottom material, ordinary Portland cement, special cement, superfine activated packing and an additive. The anti-cracking binder has the advantages that a binder hardening body is good in volume stability and does not produce shrinkage and cracking; the anti-cracking binder is a single-component product, a production process is simple, the product uniformity is good, the binder can be used through water adding and stirring in a site, any other component is not needed in the site, operation is simple, and construction is quick and convenient; the special expansive sulphate aluminum cement and the superfine activated packing are introduced to calcine metakaolin, so that the binder has high hydration rate and early-stage stretching, binding, compression and breaking resistance strength and is especially suitable for a project under the low-temperature condition in winter and limited in construction period.
Description
Technical field
The present invention relates to a kind of special cracking resistance binding agent of light cellular partition board, belongs to building material technical field.
Background technology
, due to itself having the series of advantages such as lightweight, sound insulation, heat-insulated, moistureproof, fire prevention, easy construction is fast for light cellular partition board
Speed, not only can reduce building deadweight, be conducive to improving building function, and save construction costs, reduce energy resource consumption, be
" the greening building energy saving light wall material " of Minstry of Housing and Urban-Rural Development of People Republic of China's keypoint recommendation.The high level that can be widely applied to frame structure is built
Build, industrial premises, office building, auditoriums, hotels, the locellus of residential houses and extending old building, point family, toilet, kitchen, the non-bearing such as cut-off
Body of wall is built, and is particularly well-suited to the higher place of public amusement of fire protection requirement and uses.
But, a difficult problem for the always one puzzlement industry development of construction docking of light cellular partition board, applying between partition plate
, typically in 8mm or so, longitudinal mortar joint is long for work gray seam thickness, and traditional conventional cement mortar is as sand level is with unreasonable construction hardly possible
Degree is big, and the docking mode such as cement mortar admixture glue has the shortcomings of cohesive force is not enough, volume contraction is big, operation is random big,
There is longitudinal cracking on the stress raiser surface of body of wall seam more, summarized the experience according to site operation, the wallboard of width 60cm is whole
Once more than 4.5m, there is the probability of face checking more than 80% to face width of wall body in intermediate stress concentrated part.
The content of the invention
In order to overcome drawbacks described above, the present invention to provide a kind of light cellular partition board special cracking resistance binding agent.
To achieve these goals, the technical scheme is that：A kind of special cracking resistance binding agent of light cellular partition board, by
The component of following mass parts is made：

The present invention adopts double gelling systems of Portland cement and special cement, adds organic, inorganic modified addition
Agent and superfine active filler.On the one hand the volume stability of petrifying water mudstone can be improved, is not shunk, cracking resistance；On the other hand can carry
The packing of high petrifying water mudstone itself, improves and the adhesion strength between light cellular partition board, it is ensured that the bulk strength of whole face wall body.
Aggregate used in the present invention is limestone machine-made sand undersize, is not belonging to natural resources, it is to avoid using natural
Destruction of the sand to ecological environment.
In addition, a kind of special cracking resistance binding agent of light cellular partition board proposed by the present invention belongs to one-component product, scene plus
Water is used by stirring, and need not add other any components, simple to operate, and it is convenient to construct.
The invention has the beneficial effects as follows：（1）Introduce intumescent sulphate aluminium cement, the volume stability of binding agent hardenite
Property it is good, shrinkage cracking will not be produced, through field practice confirm, one side width of wall body be up to 12m when, whole face wall body does not go out
Now along the longitudinal cracking in batten mortar joint direction；
（2）The invention belongs to one-component product, simple production process, product uniformity are good, and the scene stirring that adds water can be used, and show
Field need not fill other any components, simple to operate, quick construction, in particular for spy from light cellular partition board clump to mortar joint length
Point；The mode of glue is filled than existing ordinary mortar, efficiency of construction improves more than 1/3；
（3）Invention introduces extraordinary intumescent sulphate aluminium cement and superfine active filler calcining metakaolin, make the present invention
Binding agent there is higher hydration rate and early stage stretch-bonded, resistance to compression, rupture strength, frost resistance is good, is particularly suitable in the winter
Under season cryogenic conditions and used in duration nervous engineering, the traditional handicraft intensity effect of 28 days is can reach within 3 days.
