Abstract
The invention relates to mortar for external wall refurbishment and a preparation method of the mortar and aims at providing an external wall surface protection layer with strong adhesive force and good toughness. The mortar comprises the following components in parts by weight: 300-500 parts of white cement, 400-600 parts of white silica sand, 0.5-1.5 parts of starch ether, 2-5 parts of a water-retaining agent, 20-40 parts of emulsion powder and 3-5 parts of a thixotropic agent. The preparation method of the mortar comprises the following steps of: adding the white cement and the white silica sand into a stirrer to be uniformly stirred, then sequentially adding the starch ether, sodium polyacrylate, the emulsion powder and the thixotropic agent, and continuously and uniformly stirring and mixing to obtain the mortar for external wall refurbishment. The mortar can be used just by adding an appropriate amount of water and uniformly stirring. The preparation method disclosed by the invention is simple; the prepared mortar for external wall refurbishment has the advantages of environmental friendliness, strong adhesive force, good toughness, good air permeability and no microcrack; and in addition, the mortar can be used for resisting the damages of temperature stress caused by high temperature difference, and a smooth surface can be just obtained by simple flattening.
Description
Technical field
The present invention relates to a kind of exterior wall retrofit mortar and preparation method thereof.
Background technology
Buildings is along with extend or other external causes duration of service, and the phenomenons such as Paint Falling, wall crazing or ceramic tile come off can appear in its outside surface.Usually can the building surface that damage be renovated in prior art.In refurbishment process; can add one deck tack coat or wall guard layer between the material such as ceramic tile or mosaic and body of wall; namely renovate mortar; and the adhesive power of common renovation mortar and the material interfaces such as former metope, ceramic tile or mosaic a little less than; the ability that its anti-temperature stress destroys a little less than, easy cracking once again in environment wet by the rain and burnt by the sun.
Summary of the invention
Main purpose of the present invention is to provide exterior wall retrofit mortar that a kind of adhesive power is strong, snappiness is good and preparation method thereof.
A kind of exterior wall retrofit mortar is characterized in that: be comprised of following weight part: 300～500 parts of white cements, 400～600 parts of white quartz sand, 0.5～1.5 part of starch ethers, 2～5 parts of water-holding agents, 20～40 parts of latex powder and 3～5 parts of thixotropic agent.
Further preferably, described exterior wall retrofit mortar is comprised of following weight part: 350～450 parts of white cements, 500～600 parts of white quartz sand, 0.8～1.2 part of starch ethers, 2～4 parts of water-holding agents, 30～40 parts of latex powder and 3～5 parts of thixotropic agent.
Again further preferably, described exterior wall retrofit mortar is comprised of following weight part: 400 parts of white cements, 560 parts of white quartz sand, 1 part of starch ethers, 3 parts of water-holding agents, 32 parts of latex powder and 4 parts of thixotropic agent.
Described white cement, white quartz sand, latex powder are 70～140 orders.The particle of these several components is crossed the adhesivity that conference reduces mortar, the too small intensity that can reduce mortar of particle.
Described thixotropic agent is a kind of in polyamide wax, hydrogenated castor oil.
Described water-holding agent is polyacrylamide, sodium polyacrylate, polyacrylic acid potassium, ammonium polyacrylate and starch grafted acrylate crosslinking copolymerization thing, ethyl cellulose, Xylo-Mucine, methylcellulose gum, Vltra tears, hydroxylated cellulose ether, starch ester, wilkinite, kaolin and diatomaceous a kind of.These water-holding agents all can not produce environmentally hazardous substance.
The preparation method of described exterior wall retrofit mortar is: add stirrer to stir white cement and white quartz sand, add successively subsequently starch ethers, sodium polyacrylate, latex powder and thixotropic agent, continue to mix and namely get the exterior wall retrofit mortar.
The exterior wall retrofit mortar of preparation only need add suitable quantity of water to mix to get final product in use, and using method is simple, and mortar is with low cost.
In technique scheme, the consumption of monomer is the optimum feed stock ratio that participates in reaction, but the variation that those skilled in the art can instruction according to the present invention be equal to.For example: be equal to because the parameter that the error of industrial production itself causes changes with technical scheme of the present invention.
The exterior wall retrofit mortar of the present invention preparation has environmental protection, adhesive power is strong, snappiness good, good permeability, does not split the advantage of slit, and the destruction of can the high temperature resistance degree poor thermal stress, can obtain smooth surface by simple floating.
Embodiment
For those skilled in the art are known and clear and definite technical scheme of the present invention more, the spy provides following preferred embodiment, but technological thought of the present invention is not limited to following examples.
Embodiment one
Add stirrer to stir 400kg white cement and 560kg white quartz sand, add successively subsequently 1kg starch ethers, 3kg sodium polyacrylate, 32kg latex powder and 4kg polyamide wax, continue to mix and namely get the exterior wall retrofit mortar.
Embodiment two
Add stirrer to stir 420kg white cement and 540kg white quartz sand, add successively subsequently 1kg starch ethers, 3kg methylcellulose gum, 38kg latex powder and 4kg polyamide wax, continue to mix and namely get the exterior wall retrofit mortar.
Embodiment three
Add stirrer to stir 380kg white cement and 560kg white quartz sand, add successively subsequently 1.1kg starch ethers, 4kg ethyl cellulose, 35kg latex powder and 3kg polyamide wax, continue to mix and namely get the exterior wall retrofit mortar.
The product of embodiment one carries out Performance Detection by University Of Chongqing's construction project quality examination center according to JC/T907-2002 " concrete interface treating agent " standard, and test result is as shown in the table.
Can see from test result, the tensile bond strength of the exterior wall retrofit mortar of the present invention's preparation is all higher than 0.80MPa, and all remain on 0.80MPa after Overheating Treatment, immersion processing, alkaline purification and freeze-thaw cycle are processed more than, the weathering resistance that the exterior wall retrofit mortar that the present invention prepares is described is fine, has higher cohesive strength.Cohesive strength after 14 days is larger than the cohesive strength after 7 days, illustrates that the present invention has good weather resistance.
