Abstract
Related polymer cement waterproof paint is prepared by mixing the following raw materials according to the following formula: in parts by weight, 4-6 parts of a thickening agent, 500-700 parts of EVA emulsion, 2-4 parts of an antifoaming agent, 2-4 parts of a dispersant, 1-3 parts of a neutralizer, 4-6 parts of silica sol, 2-4 parts of a film-forming auxiliary agent, 1-2 parts of an antiseptic, and 282-482 parts of water. Compared with a conventional polymer cement waterproof paint coating, the disclosed polymer cement waterproof paint is simple in preparation technology, good in coating effect and good in tensile strength and elongation at break.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of polymer cement waterproof paint.
Background technology
Polymer cement waterproof paint is a kind of novel green waterproof paint, with the organic liquid that polyacrylate dispersion or ethylene-vinyl acetate copolymer emulsion and various additive form, with the inorganic powder of cement, quartz sand and various additive, mineral filler composition, by the compounded a kind of two-pack of rational proportioning, aqueous architectural waterproof paint.Its convenient construction, easy and wet base bonds, and the application property of film and good water-proof effect, use water as dispersion agent, environmentally friendly, so more and more receive the concern of people, in the infiltration seepy question of roofing, ground, vault, played very large effect.But everybody finds after use polymer cement waterproof paint, polymer cement waterproof paint of today still has the following disadvantages: use polymer cement waterproof paint scraped finish in construction process not easily to adhere in the market, time of drying is long, causes difficulty to construction.But what have has unit elongation tensile strength inadequate, and some tensile strengths are much of that, extend rate variance.
Summary of the invention
For the defect of above polymer cement waterproof paint, the invention provides a kind of polymer cement waterproof paint.
Technical scheme of the present invention is: a kind of polymer cement waterproof paint, and its formula is by weight percentage:
A preparation method for polymer cement waterproof paint, comprises the following steps:
Water is mixed with thickening material, under rotating speed 900 revs/min of conditions, mix and blend 10 minutes.
Add EVA emulsion, stir 30 minutes, rotating speed 600 revs/min, adds defoamer, dispersion agent, neutralizing agent during stirring.
Add silicon sol 5 parts after 30 minutes, stir 10 minutes, add film coalescence aid, stir 5 minutes, add sanitas, stir 5 minutes, rewinding obtains polymer cement waterproof paint.
Wherein: thickening material is polyacrylic ester;
Defoamer is polysiloxane;
Film coalescence aid is propylene glycol.
Waterproof paint will play good waterproof effect, needs certain thickness.Adding of thickening material makes slurry denseness increase, and strengthens shearing action, is conducive to the dispersion of color stuffing.By adding part thickening material, ensureing the easy elevation construction of polymer cement waterproof paint, not trickling; Add defoamer, decrease the size and number of pore in diaphragm, add dispersion agent, make the mixing of liquid powder more even, whipping process is more prone to; Adding of silicon sol, silicon sol molecule attached, on the surface of base material and filler particles, along with the evaporation of moisture, is dewatered between SiO2nH2O particle, forms the solid netted film that firmly Si-O key is crosslinked.The rigidity of Si-O key is stronger, without deformability, easily there is the defect such as crack, micropore in coating film forming dehydration, thus introduce organic polymer, making organic polymer be evenly distributed in Si-O key is at random coated with in intermembrane space, improves the toughness of film, shock resistance and water tolerance etc.
Film coalescence aid makes particle surface soften to the solvency action of latex particle, thus impel the easy compressive deformation of polymer particle, merges film forming.Film coalescence aid add the minimum film-forming temperature that simultaneously can reduce waterproof paint, along with the increase of film coalescence aid volume, the drying time of film also decreases.
Contain many tensio-active agents in waterproof paint, the thickening material in coating, dispersion agent etc., they have foaming tendency.And in the coating process of waterproof paint, bubble normally carrying out interference construction and the quality of film, film infiltration is all from the weakest place.The increase of bubble in obvious film, will reduce the water resistance of coating.Therefore, defoamer must be added in waterproof paint.Defoamer can soak and penetrate in thin layer that surfactant formed, by its uncompatibility and this system response, reduces its surface tension, destroys the stability of thin layer, thus reach the object of froth breaking.
Waterproof paint take macromolecular compound as the water-based material of base-material, owing to being rich in the nutritive ingredient of microorganism growth, as long as thus the envrionment conditions of the applicable microbe survival such as envrionment temperature exists, microorganism will amount reproduction, the original character of coating is destroyed, make the Quality Down of coating, even putrid and deteriorated and scrap.Therefore, antimildew disinfectant must be added in water paint.Adding of these auxiliary agents, optimize application property and the mechanical property of polymer cement waterproof paint, shorten time of drying, improve tensile strength and unit elongation.
