Abstract
The invention relates to a double component environmental protection anti-cracking watertight putty for external wall of building which comprises components A and B, wherein A comprises water, organic macromolecular polymer, wetting agent, defoaming agent, B comprises water-loss reducer, enhancing fabric, white cement, quartz powder, gypsum powder, reactive ore powder, organophilic bentonite, mica powder, andstone flour, the proportion of A component and B component is A:B=1:1.1-1.6.
Description
Technical field the present invention relates to a kind of functional architectural decoration coating material, specifically is meant the bicomponent environment-friendly type anti-crack and anti-seepage putty that is used for the external wall bottoming and scrapes Da Bai.
Background technology says that in a sense building coating is a kind of work in-process, has only through the construction film forming and attached to the coating on the basal plane to be only final finished.And in this process, though putty is the supplementary material in the building coating coating process, form a connecting link but it plays in metope basic unit and between filming, the vital role of bonding transition is also being born important functions such as preventing metope cracking, the peeling of filming, specific functionality simultaneously.
At present, poison gases such as formaldehyde are arranged with the putty of conventional formulation preparation, and easily cracking, efflorescence, batch scrape thickness deficiency, seediness, no specific functionality or the like, follow body of wall and crack owing to the variation of temperature, humidity simultaneously.These problems and then will cause the application metope disadvantages such as paint film to occur have had a strong impact on the quality of external wall.
Along with the appearance of country to building materials hazardous and noxious substances limit standard, the environmental issue of putty, also be subjected to human consumer's extensive concern, how to develop and a kind ofly require environmental protection, energy-conservation, pollution-free, high hiding rare, life-span long, the putty of easy construction and safety has become the development trend of metope base treatment putty from now on.
The application number a kind of pair of component anti-cracking exterior wall putty that be 03108713.2 patent disclosure, this pair of component anti-cracking exterior wall putty, it is made up of two components of the A of counting by weight percentage, B.The A component comprises the water of 53-60%, the organic high molecular polymer of 37-44%, the auxiliary agent of 2.4-2.8%; The B component comprises the adjusting material of 0.5-0.8%, the strongthener of 1.5-2.4%, 96-98% filler.During preparation, the A component is A: B=1 with the ratio that cooperates of B component: 1.2～1.5.Its used filler is 400 order coarse whitings by 15-18%, and the 400 order talcum powder of 30-33% and the white cement of 51-53% are formed.Used adjusting material can be selected the methylcellulose gum series products of molecular weight at 15000-30000 for use, though this type of putty can effectively prevent the putty layer cracking to a certain extent, reduce the probability of coating cracking, can be used in the exterior coating finishing system, improve the visual appearance of body of wall, but its anti-seepage effect not clearly.
Summary of the invention is for the metope of fundamentally avoiding the application exterior wall ftractures, peeling, shedding and quality problems such as peel off, further improve simultaneously the water-fast antiseepage ability of putty, the invention discloses a kind of exterior wall putty of bicomponent environment-friendly type anti-crack and anti-seepage, this putty has functional performances such as water-fast antiseepage, freedom from cracking, environment friendly and pollution-free in addition, nontoxic, non-stimulated, thick matter, fast dried, easy polishing, strong adhesion, advantages such as water-repellancy, good fluidity.
This bicomponent environment-friendly type anti-crack and anti-seepage exterior wall putty of the present invention, form by counting by weight percentage two components of A, B:
The A component comprises the water of 50-65%, the organic high molecular polymer of 35-45%, the wetting agent of 0.3-0.6%, the defoamer of 0.3-1.1%, the freedom from cracking agent of 0.5-2.5%;
The B component comprises the water-holding agent of 0.5-0.9%, the fortifying fibre of 0.6-2.0%, the white cement of 33-55%, the silica powder of 0-65%, the lime dinas of 0-25%, the terra alba of 5-14%, the active breeze of 6-25%, the wilkinite of 10-25%, the sericite in powder of 15-40%, the talcum powder of 8-25%;
The A component is A: B=1 with the ratio that cooperates of B component: 1.1～1.6.
Wherein, organic high molecular polymer is that solid content is at 45-60% in the A component, acrylate or the vinyl acetate copolymer emulsion of minimum film-forming temperature about 0-5 ℃, these copolymer emulsions also can be that acrylate, methacrylic ester or vinyl acetate are main multipolymer elastic emulsion, also can select emulsions such as pure third, phenylpropyl alcohol for use.
Freedom from cracking agent, wetting agent, defoamer are that the water-borne coatings of German Kening Co.,Ltd (Cognis) production is adjuvant used.
Selected filler is by film forming solidifying substance 425# white cement, 250-500 order terra alba and 120-400 order silica powder in the B component, and 250-400 order talcum powder is formed.
(for silica flour, specific surface area is greater than 600m by the active breeze of 250-500 order for impervious agent
2/ Kg), and 300-800 order smectites sodium bentonite, 250-400 order lime dinas, several weighting materials of 250-800 order sericite in powder are formed.
Water-holding agent is the methylcellulose gum series products of molecular weight about 15000-40000.
Fortifying fibre is that length is polyacrylonitrile fibre or the PAN base carbon fibre of 1.0-3.0mm; Cross-sectional shape as polyacrylonitrile fibre is the peanut shape, vertically is the parallel cylindrical cylindricality, and length is the 0.5-12.0 millimeter, and fineness is the 1.5-2.5 dtex, and density is 1.18g/cm
3It is big to have fiber number, characteristics such as intensity height (tensile strength is more than 300Mpa), ductility good (limit elongation is 14-20%), good hydrophilic property, acid-alkali-corrosive-resisting, weathering resistance, photostabilization are good.
In preparation, two kinds of components of A, B take known method to prepare respectively.
The A component: in stirring tank, earlier emulsion is added to the water under stirring condition, adds each analog assistant simultaneously, stirring then gets final product;
B component: terra alba, Peng Run soil, active breeze, sericite in powder, silica powder, talcum powder, lime dinas, white cement and methylcellulose gum, fortifying fibre are dried respectively, mix and get final product mediating stirrer in proportion after the weighing.
When using, at the construction field (site) A and B component are mixed in proportion to stir just can criticize and have scraped.
Selected starting material in the present invention's prescription, added the fortifying fibre of polymkeric substance, stopping composition and strengthening action with water-fast impervious effect, also mated high quality additive simultaneously, this just makes that the putty of producing can guarantee better waterproof, thickness is scraped in enough once criticizing, and has effectively prevented the putty layer cracking, and can stop the variation of body of wall Yin Wendu and humidity and the be full of cracks that produces, and then reduced the probability of coating cracking, improved the quality of finishing system.Compare with traditional wall putty, the putty that uses this prescription to produce has environment friendly and pollution-free, nontoxic, non-stimulated, thick matter, fast dried, easy polishing, strong adhesion, advantage such as water-repellancy, good fluidity, in the contrast like product, find that the present invention is applicable to that more the body of wall requirement is water-fast, impervious, the freedom from cracking place.
