Description
Technical field
The present invention relates to a kind of matrix material for building, particularly relate to a kind of mortar.
Background technology
Existing dry-mix or two-component polymer mortar all adopt ordinary Portland cement (ash concrete or white cement), grey calcium powder or dry hydrate, quartz sand, Paris white (coarse whiting, dry powder, limestone powder), wollastonite powder or talcum powder etc. to add methyl or Vltra tears, fiber etc. again, add the redispersible polymer rubber powder in addition again and are made into dry-mix or are mixed with the two-component polymer mortar jointly with polymer emulsion.Above-mentioned mortar can be used as the putty layer of exterior wall in the adhesive mortar of external thermal insulation system and motar layer, the buildings, can be used as the binding agent and the jointing agent of marble, granite, ceramic tile, can be used as mending mortar, gravity flow self-leveling floor mortar and dry powder paint etc.The main mineral binder bond of above-mentioned mortar is ordinary Portland cement and grey calcium powder or dry hydrate, the pH value that this mineral binder bond adds behind the water is respectively 13 or 14, alkalescence is very high, and because the cohesive strength of lime mortar, fragility is big, drying shrinkage, carbonization is shunk big, easily cause dried screed ftractureed the drum etc., high alkalinity has bigger corrodibility to polymkeric substance, corrodibility to glass fiber reticular cloth is bigger, easily cause grid cloth fracture in the outer heat preservation system motar layer, coat of plaster comes off, phenomenons such as the topcoating accumulation of salt in the surface soil are pasted granite, easily cause stone surface to regret flower during marble etc., phenomenons such as general moisture.
Summary of the invention
The purpose of this invention is to provide a kind of mortar, 1～7 day pH value of this mortar remains on 8～9.5, has early strong, the fast advantages such as contraction, high fillibility of doing, hang down.
For achieving the above object, the present invention adopts following technical scheme: a kind of mortar, contain following component: 10～400 parts of 250～350 parts of low basicity special cements, 0～250 part of ordinary Portland cement, 0～200 part in gypsum, filler or 300～2400 parts in aggregate, 2～20 parts of Mierocrystalline celluloses, 10～400 parts of redispersible polymer rubber powders or polymer emulsions by weight.
The present invention also can contain 2～20 parts of fibers, and the effect of fiber is to improve the splitting resistance and the workability of mortar.Described fiber is one or more the combination in wood fibre or itself and polypropylene fibre, glass fibre, polyvinyl alcohol fiber, the carbon fiber.
Also contain 0.5～10 part of retardant, 3～25 parts of hardening accelerator, the effect of retardant is to control the serviceable time of mortar, is convenient to adjust according to construction environment.The effect of hardening accelerator is to improve the early strength of mortar, is beneficial to winter construction.
Described Mierocrystalline cellulose is methylcellulose gum or Vltra tears or both combinations, and cellulosic effect is to improve the cohesive strength and the workability of mortar.
Described filler or aggregate are the combination of quartz sand or Paris white or quartz sand and Paris white.
Described low basicity special cement contains following mineral clinker component: C by weight percentage
