Abstract
The invention belongs to the field of building material adhesives, in particular relates to an external thermal-insulation dry-mixed mortar of an external wall, which is applied to adhering thermal-insulation plates on the surface of a building base wall body. The external thermal-insulation dry-mixed mortar is characterized by mainly comprising the following components in parts by weight: 25-50 parts of cement, 5-25 parts of fly ash, 45-65 parts of sand, 0.15-0.20 part of cellulose ether, 2.5-3.00 parts of subdividable gelatine powder and 0.02-0.05 part of starch ether. The preparation process of the external thermal-insulation dry-mixed mortar comprises the following steps of accurately weighing all the components in certain proportion, mixing and stirring all the components uniformly, adding water to the mixture for stirring according to the weight ratio of 100:(18-22), and then obtaining the external thermal-insulation dry-mixed mortar which can be applied to the building construction. The invention has the beneficial effects of high bonding strength, system safety, strong water preserving capability, excellent sagging resistance, excellent flexibility, frost-thawing resistance, cracking resistance and weathering resistance, low water absorption rate, small degree of shrinkage, simpleness, convenience and high-speed for construction, labor and material saving, nontoxicity, tastelessness, safety and environment protection.
Description
Technical field
The invention belongs to the material of construction adhesive area, relate in particular to a kind of basic unit's surface of wall paste heat-preserving plate external wall outer insulation dry-mixed mortar that is used to build.
Background technology
At present, building exterior wall heat preserving obtains unprecedented development as energy-conservation effective measure.External Thermal Insulation System sticks with glue agent and belongs to extraordinary mortar in the dry-mixed mortar, require that its bonding strength height, splitting resistance are good, the flawless of wiping one's face, no hollowing come off, water resistance is good, along with the popularization of External Thermal Insulation System, the external wall outer insulation dry-mixed mortar that performance is more excellent has very big market potential.The shortcoming of tradition external wall outer insulation dry-mixed mortar is: because traditional external wall outer insulation dry-mixed mortar generally all is that system is mixed in the working-yard, measure inaccurately, stir inhomogeneously, cause the wasting of resources and environmental pollution unavoidably; Mortar is impervious poor, and shrinking percentage is big, be wall crazing, flake, peel off, the weak link of construction quality problem generation such as seepage.
The main component of external wall outer insulation dry-mixed mortar-tackiness agent of the prior art is cement 350 weight parts, dicalcium powder 50 weight parts, sand 580 weight parts, re-dispersible glue powder 18-25 weight part, hydroxypropyl methyl cellulose ether 2 weight parts.Shortcoming is the cost height, and application property is bad, and product performance are poor.
Summary of the invention
Purpose of the present invention provides a kind of external wall outer insulation dry-mixed mortar, easy construction, and splitting resistance is good, the flawless of wiping one's face, no hollowing come off, water resistance is good.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of external wall outer insulation dry-mixed mortar is characterized in that, mainly by following compositions by weight ratio make:
25～50 parts of cement;
5～25 parts in flyash;
45～65 parts of sands;
0.15～0.20 part of ether of cellulose;
2.5～3.0 parts of re-dispersible glue powders;
0.02～0.05 part of starch ethers.
Described cement is the ordinary Portland cement more than 42.5 grades.
Described flyash is selected C class flyash or the F class flyash that meets GB/T1596-2005 standard seconds index for use.
Described sand is the river sand of granularity continuous grading in 0.1～0.5mm scope.
Described ether of cellulose is methyl hydroxyethylcellulose ether (MHEC) or methylhydroxypropylcellulose ether (MHPC) or both mixtures.
Described re-dispersible glue powder composition is vinyl acetate-ethylene or vinyl acetate between to for plastic-tertiary monocarboxylic acid ethene or both mixtures.
Described starch ethers composition is a hydroxypropylated starch ether.
Described a kind of external wall outer insulation dry-mixed mortar preparation technology, it is characterized in that, after each component accurately measures in proportion, join in the mixing equipment successively, stir, be finished product after in bulk or packed, dry-mixed mortar and water add the water stirring by 100: 18～22 weight ratios during use, promptly can be used for building operation.
The present invention is owing to use the cement and the re-dispersible glue powder of high strength grade, makes the intensity height of product, and is flexible good, the splitting resistance height; Because the new starch ethers that adds, starch ethers and ether of cellulose act synergistically, and can obviously improve the anti-property and the anti-slipping property of hanging down of mortar, have higher yield value; Obviously increase the denseness of mortar, improve mobile; Increase the water-retentivity of mortar, prolong the open hour.Strengthen the product degree of compactness, improved the water resistance of product.Owing to add flyash, utilized industrial residue, reduced product cost.
