Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of flexible polymer composite anti-penetrating cracking-resistant cement mortar
Preparation method.
Background technology
With the continuous development of building industry, to the quality requirement more and more higher of engineering, the performance of cement mortar is as shadow
An important factor for ringing construction quality, turn into the focus of research.High-quality building building cement mortar should be able to meet certain deformation and keep
Indehiscent requirement, there is the characteristics of strong bonding force, cracking resistance, waterproof.Existing conventional cement mortar used for building exterior wall typically by
Cement and sand, which mix and stir, to be formed, its tear-proof, water resistance deficiency, and intensity difference, is easily caused metope cracking, hollowing, is come off
The problems such as, architectural appearance is not only influenceed, also reduces the durability of building.Therefore to improve structural quality, building water is improved
Cracking resistance, the water resistance of cement mortar are most important.
The content of the invention
A kind of the defects of the object of the invention is exactly to make up prior art, there is provided flexible polymer composite anti-penetrating cracking resistance water
The preparation method of cement mortar.
The present invention is achieved by the following technical solutions：
A kind of preparation method of flexible polymer composite anti-penetrating cracking-resistant cement mortar, it is characterised in that comprise the following steps：
（1）Raw material is weighed by weight, and 0.3-0.5 parts hydroxyethyl cellulose and 0.3-0.5 parts Sodium Polyacrylate are first added into 30-40
Fully dissolved in part water, then add 5-10 part calcium nitrate solutions and be well mixed, being slow added into ammonium dibasic phosphate solution makes calcium
Phosphorus ratio is 1.53-1.67, and pH is adjusted into 9.5-10 and stirs 4-6h in 40-60 DEG C, is then slowly added into 0.2-0.3 parts silane idol
Join agent A-151 and 6-8 part absolute ethyl alcohols mixed liquor, be warming up to 70-80 DEG C and continue to stir 4-6h, adding 3-5 parts after cooling can
Redisperse latex powder is well mixed, and obtains mortar modifier；
（2）By 100-150 parts cement, 10-15 parts flyash and step（1）In grind after obtained mortar modifier mixing it is equal
It is even, then add in mixer and stir jointly with 200-250 parts quartz sand, 1.5-2.5 parts polypropylene fibre and 80-120 part water
Uniformly, flexible polymer composite anti-penetrating cracking-resistant cement mortar is obtained.
Preferably, the concentration of the calcium nitrate solution is 0.15-0.25mol/L.
Preferably, the concentration of the ammonium dibasic phosphate solution is 0.15-0.25mol/L.
Preferably, the polypropylene fibre length is 5-8mm.
Preferably, the step（2）In milling time be 20-30min.
Preferably, the step（2）In mixing time be 3-5min.
It is an advantage of the invention that：
The present invention is received by the way that calcium nitrate solution is blended in into the generation of hydroxyethyl cellulose solution situ with ammonium dibasic phosphate solution
Rice hydroxyapatite, so as to obtain uniform nanometer hydroxyapatite/hydroxyethyl cellulose original position doping system, hydroxyapatite
With tetrahedral network structure so that the system can form dimensional network structure in mortar, improve mortar stability and
Crack resistance；Again by adding the ethanol solution of silane coupling A -151 into system, silane coupling A -151 is hydrolyzed and is grafted
To nanometer hydroxyapatite surface, the hydrophobically modified in situ to nanometer hydroxyapatite is realized, so as to assign nano-hydroxy-apatite
Stone/good the hydrophobicity of hydroxyethyl cellulose system.Mortar is obtained after system addition polymer dispersion powder is well mixed to change
Property agent, nanometer hydroxyapatite/hydroxyethyl cellulose system in the mortar modifier can improve the compactness of mortar and anti-
Split, water resistance, soft segments redispersable latex powder improves bond strength, the water resistance of mortar, admixes cement, fine coal
Obtained cracking-resistant cement mortar has excellent antiseepage, cracking resistance after the cement mortar raw material such as ash, quartz sand, and durability degree is high,
Service life is grown, and can significantly improve the quality of building.
