Description

A kind of polymer cement waterproof paint and preparation method thereof
Technical field
The present invention relates to water-repellent paints, and in particular to a kind of polymer cement waterproof paint and preparation method thereof.
Background technique
Construction waterproofing engineering is the important component of modern construction engineering, is needed in the construction process according to using need Ask to select suitable waterproof material, thus develop high-performance, low cost, can the strong waterproof material of application property be always build it is anti- The research emphasis in water field.In existing architectural engineering common waterproof material mainly include rigidity water-proofing material, waterproof roll, Water-repellent paint, sealing material and some other waterproof material.Wherein polymer cement waterproof paint is by synthesizing macromolecule Polymer emulsion (such as polyacrylate, polyvinyl acetate, SBR emulsion) and various additives optimum organization form Liquid material and the bi-component waterproof that is combined of matched powder (being made of special cement, silica flour and various additives) apply Material is a kind of not only with the waterproof material that synthesising macromolecule copolymer elastic properties of materials is high but also organic and/or inorganic materials durability is good, wide It is general be applied to that kitchen, toilet, metope be moisture-proof and the engineerings such as basement is moisture-proof in.
White cement due to having many advantages, such as good decorative property, it is good with the color compatibility of polymer emulsion, be normally used as gathering Close the component part of powder in object cement waterproof paint.However, the white cement of high grade is since fineness is low, when aquation starts calcium from Sub- rate of dissolution is fast and polymer emulsion it is common in the presence of, interaction between the two makes to be easy to produce flocculation knot inside slurry Structure, so that the viscosity of water-repellent paint be caused to become larger, and viscosity rise at any time it is too fast.Viscosity rises the levelability so that slurry It declines to a great extent, greatly affected water-repellent paint can application property and the engineerings such as subsequent patch block and surfacecti proteon.Therefore, urgently A kind of viscosity regulation method of polymer cement waterproof paint need to be found, the viscosity in water-repellent paint use process is reduced, to protect Demonstrate,prove water-repellent paint can application property.

Preferably, the polyacrylate dispersion is blue emulsion.
Preferably, the viscosity modifier is polycarboxylic acid series additive, with diminishing, sustained release, adjusts the multi-functionals such as viscous, For aqua, solid content is 16wt.% or so.Viscosity modifier is more preferably I type 1#, PCA- of PCA-, I type 2#.
Preferably, the white cement is 52.5 grades of white cements.
Preferably, the partial size of the quartz sand is 100-200 mesh, is superfine quartz sand.
Preferably, the water-reducing agent is naphthalene water reducer, is pulvis.Water-reducing agent be more preferably highly concentrated type (sodium sulphate content < 5%), low dense type (sodium sulphate content about 20%) naphthalene water reducer.
Preferably, the retarder is sodium gluconate, is pulvis.
Second aspect of the present invention provides a kind of preparation method for preparing above-mentioned polymer cement waterproof paint, including following step It is rapid: to add the viscosity modifier of formula ratio into liquid material, then add the powder of formula ratio, be mixed evenly to obtain polymer water Mud water-repellent paint.
Preferably, the equipment used that stirs is egg-whisk, and low speed (400-500r/min) stirs 2-3min, stops 15- 30s, high speed (800-900r/min) stir 1-2min.
The utility model has the advantages that (1) polymer cement waterproof paint provided by the invention, can by the way that a kind of viscosity modifier is added It is substantially reduced viscosity of the polymer cement waterproof paint in 3h, and can make viscosity that the trend gently risen, viscosity be presented Regulating effect is more excellent, solves the problems, such as that the polymer cement waterproof paint viscosity of script is big and it is fast to rise, ensure that in reality In use process can application property;And not be viscosity modifier dosage more multiple-effect fruit it is better, when the dosage of viscosity modifier is super After crossing 1.5%, other performances of coating can be had an impact, such as the excessively high generation of volume isolates, setting time is impacted.(2) The viscosity regulation method of polymer cement waterproof paint provided by the invention does not change the match ratio of former coating, only need to be in liquid material A kind of viscosity modifier is added, easy to operate, cost is controllable, it is easy to accomplish.
