Abstract
The invention provides polymer crack-resistant mortar, which is prepared with 25 to 35 percent of cement, 55 to 65 percent of sand, 5 to 10 percent of pulverized fuel ash, 2 to 4 percent of soluble powdered gum, 0.1 to 0.5 percent of wood fiber, and 0.2 to 0.5 of hydroxypropyl methylcellulose through mixing. All of the indices of the polymer crack-resistant mortar meet the standard requirements of the Material for Exterior Wall Thermal Insulation System of Buildings (DBJ04-234-2005); the distortion resulting from drying shrinkage of the polymer crack-resistant mortar is small; the cohesive strength is high with high crack resistance, placeability and moisture retention; the hardened polymer crack-resistant mortar can be bonded to the wall or other parent materials well, and can prevent internal wall and external wall from cracking. The beating uniformity is high; the quality is stable; and the quality of building construction is guaranteed by adopting the polymer crack resistant mortar for construction.
Description
Technical field
The present invention relates to a kind of building dry powder mortar, particularly relate to a kind of heat insulating system top layer and smear the decoration anticracking grout.
Background technology
Along with people to improving constantly that the quality of building and attractive in appearance and comfort level require, material of construction is also had higher requirement.Constantly the production application of novel energy-conserving materials for wall of releasing such as gas concrete, light ceramic hollow brick, hollow fly ash building block etc. has not only improved the building operation quality, has improved body of wall thermal insulation and permeability, has also solved many environmental issues.But at present the scene of generally using is stirred mortar and is not only existed qualitative problems of construction such as leak, crack, cohesive strength are low, easily peel off, and acts on singlely, only can play the effect of walling glue stick.
The building function mortar is as a kind of novel green material of construction, is widely used in countries such as China and the U.S., Europe.The difference of function mortar and traditional mortar is, the function mortar is wiped one's face except building by laying bricks or stones of traditional mortar the function, also has heat insulating, water-proofing anticracking, inhale ripple, sound absorption and specific function such as corrosion-resistant, and in use saved hand mixing, not only there is not waste of material, and the mixing evenness height, steady quality.
On the basis of traditional mortar, by allocating different function admixtures into, can give mortar with special function, make the building function mortar of various uses, more traditional mortar has remarkable advantages.
The materials for wall ubiquity that uses in the construction work serious wall crazing and leakage problems, has had a strong impact on construction quality and normal the use.Materials for wall rimose major cause except the structural cracks that uneven settlement of foundation etc. causes, mainly be since traditional sand-cement slurry or mixed mortar self shrink big, cohesive strength is low and unreasonable with the solid clay brick coupling, causes the control wall crazing.To the cracking problem that occurs in the materials for wall application, still do not have effective measure so far and controlled.
Produce the required raw material of dry-mix and mainly contain building materials such as sand, cement, and some consumptions chemical additive seldom.Although dry-mix is used widely, the water-retentivity of mortar, cohesive force, splitting resistance and become the difficult problem that industry needs to be resolved hurrily with the coupling of basic unit's (for example materials for wall).
Summary of the invention
The objective of the invention is to overcome the defective of present common building dry powder function mortar, a kind of cohesive strength height, dry-shrinkage deformed little is provided, have the polymers anti-cracking mortar of good resistance to cleavage.
Polymers anti-cracking mortar of the present invention is made up of according to certain mixed cement, sand, flyash and admixture, and its raw material weight per-cent consists of:
Cement 25～35%
Flyash 5～10%
Sand 55～65%
Solubility rubber powder 2～4%
Wood fibre 0.1～0.5%
HPMC 0.2～0.5%.
Wherein, described cement is the 425# silicate cement, and described sand can be one or more the combination in yellow ground, river sand or the quartz sand.
The concrete preparation method of polymers anti-cracking mortar of the present invention is:
Above-mentioned various raw materials after the super-dry pre-treatment, are added in the stirrer according to weight proportion weighing cement, flyash, sand and solubility rubber powder, wood fibre, HPMC and to stir 5～10 minutes, packing product.
The using method of the polymers anti-cracking mortar that the present invention prepares is: according to anticracking grout: the weight ratio of water=1: 0.2～0.25, add entry earlier, add anticracking grout again, fully stirred 3～5 minutes, evenly can use to material, use with reference to consumption 4～5Kg/m
2The mortar that mixes is preferably within 2 hours and uses up.
The present invention adopts ordinary Portland cement as inorganic coagulation material, the solubility rubber powder is organic consolidating material, according to certain mixed, and adopt sand and flyash for gather materials, filler, adding an amount of chemical materials is additive, has formed the splendid adhesive material of performance, product tensile bond strength (with expansion polyphenyl plate) 0.144MPa, snappiness (backfin ratio) 2.8, ultimate compression strength 8.8MPa, water regain 487g/m
2, operable time 2h, all index reaches DBJ04-234-2005 " External Thermal Insulation System product (material) " standard-required, the cracking of exterior wall in can preventing fully.
Polymers anti-cracking mortar processing of the present invention is simple, and product cohesive strength height is dry-shrinkage deformed little, has good resistance to cleavage, workability and water-retentivity, and the sclerosis back has higher cohesive force with materials for wall or other body materials.Adopt polymers anti-cracking mortar of the present invention to construct, the mixing evenness height, steady quality has guaranteed the quality of building operation.
