Abstract
An environment protection type insulating anti-cracking putty for wall is composed of the component A prepared from water, organic high-molecular polymer, wetting agent, defoaming agent, and anti-cracking agent, and the component B prepared from hollow microbeads, water preservating agent, reinforcing fibres, white cement, heavy calcium, quartz powder and wollastonite powder. The ratio of A to B is 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 heat-insulation and heat-preservation anti-crack mastic that is used for interior exterior 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 to be only final finished attached to the coating on the basal plane.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 putty that has been 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 it is used in when requiring insulation, heat insulation metope, and effect but is 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, and satisfies the specific demand of different metopes, and the selection of supplementary material---putty is very important.The invention discloses a kind of bicomponent environment-friendly type heat-insulation and heat-preservation anti-crack mastic product, functional performances such as that this putty has is heat insulation, insulation, high temperature resistant, freedom from cracking, and have nontoxic, thick matter, fast dried, easy polishing, strong adhesion, advantages such as water tolerance, good fluidity.
This bicomponent environment-friendly type heat-insulation and heat-preservation anti-cracking outer wall mastic 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 cenosphere of 9-33%, the water-holding agent of 0.5-0.9%, the fortifying fibre of 0.6-2.0%, the white cement of 33-55%, the coarse whiting of 10-30%, the silica powder of 20-40%, the wollastonite powder of 6-20%.
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, the acrylate copolymer emulsion of minimum film-forming temperature about 0-5 ℃, these copolymer emulsions can be that acrylate and methacrylic ester 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 then is by 100-400 order coarse whiting in the B component, 120-400 order silica powder, and 250-400 order wollastonite powder, the 425# white cement is formed.
The cenosphere specification is the nonmetal multifunctional material of lightweight of the special processing of process of 0.2-400 μ m, and main component is SiO
2And Al
2O

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: get final product with mixing at the kneading stirrer in proportion after cenosphere, dicalcium powder, silica powder, wollastonite powder, white cement and methylcellulose gum, the fortifying fibre 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, improved the solid content of finished product, the cenosphere with heat-insulation and heat-preservation effect and the fortifying fibre of strengthening action have been added simultaneously, mated high quality additive, these make the putty produce can guarantee that enough once criticizing scrape thickness, also strengthened the heat-insulation and heat-preservation effect of body of wall simultaneously, 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 nontoxic, thick matter, does soon, easily polishing, strong adhesion, and advantages such as water tolerance, good fluidity are particularly useful for that the body of wall requirement is heat insulation, insulation, high temperature resistant, freedom from cracking place.
