Description

The super-weather resistant alkali-activated-fly ash-slag bicomponent outer wall inorganic paint
Affiliated technical field
The present invention relates to the production technical field of building external paint, specifically, relate to the production technical field of super-weather resistant alkali-activated-fly ash-slag bicomponent outer wall inorganic paint.
Background technology
Coating is made up of base-material and filler, chemical reaction does not take place in base-material and filler, base-material is a film forming material, the performance of coating is by the performance decision of base-material, so multiselect is made base-material with the good material of performance, as fluorine coating, because its base-material fluorine material property is good, it become integrate decoration, beautify, anticorrosion high-grade paint.Two component exterior coatings of potash water glass and for example, to the potash water glass modification, the resultant after the modification is as base-material with solidifying agent, the base-material and the filler generation chemical reaction of getting along well.Base-material is that organic materials is called organic coating, and base-material is that inorganic materials then is called inorganic paint.Exterior wall organic architecture coating is petroleum chemicals, and production energy consumption height, cost height are produced and use discharging VOC.Alkaline resistance properties is the weakness of organic coating, therefore must prime earlier, reduces or stop the destruction of highly basic opposite coating films such as body of wall cement, and organic exterior coating is that a kind of price is higher, and the non-energy saving and environment friendly coating of certain contaminative is arranged.The exterior wall inorganic architectural coatings has a plurality of kinds, and is more crisp, easy to crack as filming of silicon sol single component exterior coating, with water glass or potassium silicate is the outer wall inorganic coating of base-material, abrasion resistance is undesirable, the wash-resistant property of standard JG/T26-2002 〉=1000 time, and standard is too low.2001.12 phases of New Building Materials magazine have been introduced a kind of " alkali slag inorganic paint ", its washability number of times 〉=3000 time, but because of the time of coagulation of coating short, the brushing operating time can not surpass half an hour and can't use.2008.12 phases of New Building Materials magazine have also been introduced a kind of " slag water glass exterior coating ", and its cohesive strength is 0.57MPa, and only the index 0.49MPa than standard GB 1022-88 is high slightly.
The purpose of this invention is to provide a kind of washability number of times 〉=more than 25000 times, cohesive strength is 1.14MPa, operating time 2-4 hour super-weather resistant alkali-activated-fly ash-slag bicomponent outer wall inorganic paint of brushing.
Summary of the invention
The method that realizes super-weather resistant alkali-activated-fly ash-slag bicomponent outer wall inorganic paint of the present invention is:
At first select for use with sodium silicate and water and make base-material, with flyash, high-alumina cement, slag, titanium dioxide, pigment, talcum powder, redispersable latex powder, Natvosol, naphthalene water reducer, powdery defoamer is filler, prepares base-material and filler after raw material is selected in the following manner:
Base material formulation is: sodium silicate (volume): water (volume)=1: 1;
Filler formulation is weight (%): flyash or slag or flyash and slag compound or with the compound 25-80% of other silica-aluminum materials; High-alumina cement 0-50%; Titanium dioxide 0-10%; Talcum powder 5-15%; Pigment 3-5%; Redispersable latex powder 4-6%; Natvosol 0.4-0.6%; Naphthalene water reducer 0.5-0.8%; Powdery defoamer 0.05-0.1%;
The mixing match of the base-material of coating and filler is during use: base-material (volume): filler (weight)=1-1.5: 1;
Its producing and manufacturing technique of the selected back of proportioning raw materials is: one, base-material processing is that sodium silicate and water are mixed stirring in container, and churning time is 5-10 minute; Two, the processing of filler is the filler for preparing in proportion to be mixed levigate, makes the fineness ratio surface-area 〉=500m of filler 2/ kg.
Method of the present invention is to adopt base-material and filler generation chemical reaction, by the film forming technological line of resultant of reaction, make base-material with sodium silicate, make filler with flyash, slag or other silica-aluminum materials, necessary modification before this filler uses, otherwise the snappiness of coating is poor, crisp and condense soon, does not fill surplus brushing operable time.The measure content of modification is: 1. filler use flyash and slag are compound, or flyash and other silica-aluminum materialses are compound, or slag and other silica-aluminum materialses are compound, the resultant of matrix material and sodium silicate reaction reacts with sodium silicate than single flyash or slag, and resultant has better mechanical property and retarding effect.When the preparation light-coloured coating, can add high-alumina cement, slowed down reaction speed has when guaranteeing the coating brushing and fills surplus operable time.2. add an amount of redispersable latex powder, improve the snappiness of filming, more than belong to modification for the first time.3. preparing the filler that finishes must only carry out mechanical force modification and coating modification in the levigated process to filler through levigate, could realize effective modification, can improve the activity of filler greatly, guarantees the abundant reaction of base-material and filler, guarantees bright-colored.The final fineness ratio surface-area of filler is answered 〉=500m 2/ kg belongs to modification for the second time.4. suitably reduce the concentration of sodium silicate solution, slow down the speed of response with filler, guarantee the operable time of coating brushing.Belong to modification for the third time.Sodium silicate mixes the back alkali takes place to be excited chemical reaction with filler after the modification, generate alkali and excite gelling material, its composition is a geopolymer, low basicity hydrated calcium silicate, zeolite, mineral such as class zeolite, so this coating has geopolymer and has organism concurrently, pottery, cement, the characteristics of materials such as glass, be different from above-mentioned materials again, the collection of filming that forms is high-strength, the high adhesion, corrosion-resistant, high durable advantage, if not to its modification, then the coating existence is condensed and can't be brushed operation soon, snappiness is poor, crisp defective, through filming after three modifications of above-mentioned four measures in its gelling material advantage of maintenance, accomplish that the snappiness of filming significantly improves, check with 1mm grid delineation method, 100% is qualified, the operable time of brushing reaches Xia Qiu 2h-2.5h, early spring, winter 3h-4h has satisfied construction requirement, makes this coating become fine exterior wall inorganic architectural coatings.The novelty of this coating: changed conventional coating by the film forming pattern of base-material, react the new mineral of generation this new technology path of filmogen with base-material and filler as coating, film and kept the advantage of newly-generated mineral, its defective is then made coating have good performance by three modifications and fills the surplus operable time of filming, flexible filming.Produce with industrial waste and to have premium properties and have again and fill surplus brushing operable time, the exterior wall inorganic architectural coatings that snappiness is good.Coating is through testing abrasion resistance: test specimen is scrubbed number of times 25000 times, and nothing is bubbled, nothing ftractures, nothing comes off; Water tolerance: test specimen immersion 4320h, nothing is bubbled, nothing ftractures, nothing comes off; Acidproof rain: test specimen soaks in PH=3 solution, adjusts PH every day, keeps PH=3, soaks 960h and does not have foamings, do not have cracking, nothing comes off; Salt tolerant, alkali resistance: test specimen is immersed in and soaks in the 0.2mol/LKOH solution of 5%NaCl that 960h does not have foamings, do not have cracking, nothing comes off.Cohesive strength: 1.14MPa; Snappiness: the check of 1mm grid delineation method, 100% is qualified.
