Abstract
The invention discloses geopolymer dry-powder paint as well as a preparation and use method thereof. The dry-powder paint is prepared by mixing mixed powder S1 and solid sodium (or potassium) water glass powder S2 serving as raw materials, wherein the mixed gas S1 comprises metakaolin, titanium dioxide, calcium carbonate powder and quartz powder. The geopolymer dry-powder paint has the characteristics of high strength, water resistance and ageing resistance, low cost, nontoxic, environment friendliness and the like, and is easy to store; metakaolin and solid water glass react and are solidified to form a film; the titanium dioxide powder, calcium carbonate powder and quartz powder are added to adjust to gain proper film modifying time as well as improve the features of film coating. The prepared paint can be coated on a cement mortar surface, a putty surface, a ceramic surface and a wood surface by brushing, rolling or spraying.
Description
Technical field
What the present invention relates to is single-component geopolymer dry powder paint field, can be used for that sand-cement slurry surface, putty surface, ceramic surface, wood surface are brushed, roller coating or spraying; Specifically a kind of geopolymer dry powder paint and preparation method and using method.
Background technology
Gelling material refers generally to powder process and water mix, has certain gelling, after the regular hour, can condense or curing material.For example, cement is exactly a class gelling material of current use range and usage quantity maximum.Geology polymer material is a kind of alkali excited cementing material, but most of alkali excites geopolymer to adopt water glass as exciting agent, is not easy to transportation and stores in use procedure.For this reason, prepare single-component geopolymer dry powder paint, in use, only need to add water and just can use, use and store convenient.Thereby the present invention has very important significance.
Late 1970s, first the J.Davidovits of France proposes the concept of geology polymer material.This material has the hardness higher than macromolecular material, thermostability and resistance of oxidation, but toughness is not as good as organic polymer; Compare with stupalith, the structure of geopolymer is the continuous three-dimensional network framework forming with closed chain, there are two kinds of structures of " quasi-crystalline " and vitreous state, there is not crystal and crystal boundary completely, the properties of material comes from [-Si-O-Al-O-] n skeleton, the performance of geopolymer and ceramic-like like but do not need sinter molding.Compare with cement material, the extent of polymerization of geopolymer is higher, after reaction, there is oxide compound three-dimensional net structure, at high temperature also can keep network structure complete, thereby geopolymer has the intensity higher than cement, hardness, toughness, water tolerance, high-temperature stability and frost resistance.
Exactly because geology polymer material has early stage high strength, erosion resistance is good, frost resistance is good and normal temperature under react curing feature, can be applied to the civilian and Industrial buildings of engineering patching material and cast in situs, be time of coagulation and the rear accumulation of salt in the surface soil problem producing of sclerosis of geology polymer material but need the key issue solving; Through repeatedly groping experiment, the present invention is by regulating the incorporation of metakaolin consumption, solid water glass modulus and proportioning and water, make it obtain the suitable condensation cure time, increased the controllability of geopolymer coating setting time, also greatly improved the utilization ratio of material, reduced production cost simultaneously.
Summary of the invention
Some intrinsic defects that have for solving traditional architecture coating, as not high in organic film forming coating hardness, not water-fast and easy aging feature, the present invention adopts inorganic materials as film forming matter, by other inorganic powder of admixture, carry out modification and enhancing, obtained that good film-forming property, intensity are high, the full-inorganic building coating of asepsis environment-protecting; The density of this material reaction post-hardening body only has 1.6-1.9g/cm3, particularly has very strong bonding force with cement sand bed, can directly be applied on cement sand bed as putty layer or directly as surface material; If can directly be combined with screed as surface material, the putty layer in the middle of exempting, thereby there is usage space more flexibly, if as outer wall coating, have more water-fast, weather-proof advantage.Because the speed of response of metakaolin and water glass is very fast, according to cement setting time bioassay standard, final setting time only has 2-3 hour, even also only have 6-10 hour after toning is solidifying; Therefore the geopolymer coated material that prepared by our early stage patent of invention (ZL200810009009.3) can only be made two-pack, after before use solid phase and liquid phase component being stirred, just can construct.
The present invention is in order to solve the more existing intrinsic defects of above-mentioned coating, as complex manufacturing, the features such as high energy consumption, high pollution, high water consumption, the invention provides a kind of employing metakaolin and solid water glass as main raw material, by admixture filler, regulate time of coagulation, obtained good geopolymer dry powder paint and preparation method and the usage of workability.
