the test results are given in the following table:
TABLE 2 test results of the Performance of the polymer cement waterproof coating materials prepared in examples 1 to 5 and comparative examples 1 to 3
As can be seen from the above table, the polymer cement waterproof coating prepared in the embodiments 1 to 5 of the present invention has significantly improved tensile strength and elongation at break, as high as 5.8MPa, as high as 658%, good adhesive property, as high as 2.9MPa, good water impermeability, which is water impermeable at 0.3Map for 90min, good impermeability, as high as 2.2MPa, and better low temperature flexibility, and no crack at-30 ℃. The raw material proportion and the preparation method of the embodiment 5 are relatively better technical schemes of the invention, and the prepared polymer cement waterproof coating has the best performance.
Compared with the polymer cement waterproof coating prepared in example 5, the waterproof coating prepared in comparative example 1 has poor tensile property, low tensile strength and elongation at break, and relatively poor low-temperature flexibility, water resistance and impermeability, and a compatilizer is not added in the formula of the waterproof coating prepared in comparative example 1, which indicates that the addition of sodium bis (laurylaminoglutamide), poloxamer and polyethylene glycol in the compatilizer obviously improves the tensile property, water resistance, low-temperature flexibility and impermeability of the waterproof coating, because the sodium bis (laurylaminoglutamide), poloxamer and polyethylene glycol are matched to obviously improve the interfacial compatibility of powder mixed by cement, heavy calcium powder and quartz sand and styrene-acrylic emulsion, the sodium bis (laurylaminoglutamate) lysine has amphiphilicity and amphiphobicity, and the surface tension is very low, so that the sodium bis (laurylaminoglutamate) can permeate into the powder and the styrene-acrylic emulsion, the modified water-proof coating is compatible with poloxamer and polyethylene glycol, so that powder materials are better dispersed in styrene-acrylic emulsion, the tensile property and the bonding property of the water-proof coating are improved, a large amount of heat is generated in a system along with the progress of a cement hydration process in the use process of the water-proof coating, the polyethylene glycol has a lower melting point, is heated and melted and is matched with sodium bis (lauramide glutamine) lysine, on one hand, the viscosity of the system is increased, the density of the system is improved, on the other hand, a layer of compact oil film is formed on the surface of the coating, and the water resistance and the impermeability of the water-proof coating are further improved.
Compared with the polymer cement waterproof coating prepared in the example 5, the waterproof coating prepared in the comparative example 2 has relatively poor tensile property, water resistance and impermeability, and the waterproof coating prepared in the comparative example 2 is not added with a retarder, which indicates that the addition of carboxymethyl chitosan and sucrose stearate in the retarder obviously improves the tensile property, water resistance and impermeability of the waterproof coating.
Compared with the polymer cement waterproof coating prepared in the example 5, the comprehensive properties of the waterproof coating prepared in the comparative example 3, such as tensile property, low-temperature flexibility, adhesive property, waterproofness and impermeability, are relatively poor, and the dry mixture and all the mixed solutions are directly mixed in the preparation method of the waterproof coating prepared in the comparative example 3 instead of mixing step by step, which shows that the dry mixture is firstly added into the mixed solution with half volume and uniformly mixed, and then the mixed solution with the rest volume is added, so that the comprehensive properties of the waterproof coating are remarkably improved, because the dry mixture is firstly added into the mixed solution with half volume and uniformly mixed by ultrasonic dispersion in the preparation step, and then the mixed solution with the rest volume is added, so that the powder mixed by cement, heavy calcium powder and quartz sand is more uniformly dispersed in the mixed solution mixed by styrene-acrylic emulsion, cationic starch and poly-N-isopropylacrylamide, the phenomenon that slurry overflows due to nonuniform mixing caused by agglomeration due to insufficient wetting of powder in the powder and liquid mixing process is effectively avoided, and therefore the comprehensive performance of the coating is improved.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
