Abstract
The present invention discloses building paint which contains silicon base nanometer materials. Building paint used at present does not have effective measures for improving suspension property, bond strength, aging resistance and pollution resistance. The present invention causes nanometer oxygen deficit silicon base oxides to add in the existing building paint, and thereby, the present invention greatly enhances the aging resistance, the bond strength, the pollution resistance, the suspension property, etc.
Description
What the present invention relates to is a kind of building coating, and particularly a kind of building coating that contains nano material specifically is exactly the building coating that contains the oxygen debt silicon-base oxide of nanometer.
Building coating is widely used in building field, uses the high-quality building coating of high-performance, can improve construction quality.The production technique of building coating is comparatively simple, and the performance that hope improves building coating by the change production technique is the comparison difficulty.Therefore, people's handle changes formulation for coating material, or adds different activated feedstocks as the feasible way that improves the building coating performance and improve the quality.At present, in building coating, people concentrate on aspects such as improving its water resisting property, brushing resistance, tack to the focus of improving its performance.As: application number is 93101393 Chinese invention patent application, by adding unslaked lime and crystalline inorganic salt, the water tolerance of raising coating, alkali resistance, brushing resistance, weathering resistance etc.Application number is 94109287 Chinese invention patent application, adds to contain in coating-macromolecular compound of ON base, with the waterproof that improves coating, anticorrosion, oil resistant, wear-resisting and other performances.Yet in fact performances such as the suspension of building coating, thixotropy, resistance to deterioration and cohesive strength all are important, and these performances good or bad determined the class height of building coating and the quality of quality." pigment suspension " performance is good, and coating is difficult for layering in depositing process rotten, and storage period is long.Some structure that thixotropy refers in the coating is separated under the effect that external force is sheared, and external force can be restored rapidly after eliminating, and structure is recombinated rapidly.The shearing force reduction reaction of this dependence time and external force effect and reinstatement is called thixotropy, and thixotropic property is good, and then coating is easy to construction, and is highly polished, good weatherability, and surface drying time shortens, and is anti-aging.Therefore, thixotropic property is the principal element that influences the every performance of coating.How to improve these performances, present way is to add thickening material as methylcellulose gum, Natvosol and ultraviolet absorbers etc. in coating.However, the raising of performances such as its " pigment suspension " property, thixotropy, resistance to deterioration, smooth finish is still extremely limited.
Nanometer is a length metering unit, the material grains diameter is called nanoparticle less than the powder aggregate of 100 nanometers, nanoparticle has unusual or unusual physics, chemical property, as: surface effects, quantum size effect, small-size effect and macro quanta tunnel effect are added nano material in the goods that need this material to, and then every function of these goods, performance index all can increase substantially.Yet yet there are no the open report that nano material is applied to coating, application number is 96117127,92105939 and 93107558 Chinese invention patent application, and disclosed all is preparation of nanomaterials, and does not relate to its application in coating.
Purpose of the present invention prepares a kind of building coating of siliceous based nano-material exactly, to improve the performances such as pigment suspension, thixotropy, resistance to deterioration and caking ability of building coating.
For achieving the above object, the present invention has taked such measure, a kind of building coating of siliceous based nano-material, prepare according to a conventional method, it comprises base-material, aggregate, auxiliary agent and water, and adds the oxygen debt silicon-base oxide SiO of nanometer of 0.1-3.0% by the weight percent of above-mentioned other the outer raw material that dewaters
2-X, the value of X is 0.4-0.8, described nanometer is oxygen debt silicon-base oxide SiO
2-XBe meant the nanoparticle that subtracts the oxygen debt silicon-base oxide polymkeric substance that 0.4-0.8 oxygen and 1 silicon forms by 2.Preferred version of the present invention is the nano silicon-based oxide SiO that adds 0.5-1.5% by the weight percent of above-mentioned other the outer raw material that dewaters
2-X
Take the present invention of above-mentioned measure, in coating, add the oxygen debt silicon-base oxide SiO of nanometer
2-xAfter, because of its particle is small, specific surface area is big, can be when coating be dry very fast formation network structure, the stripping strength of coating and smooth finish are increased considerably, nanometer is oxygen debt silicon-base oxide SiO
2-xBe a kind of ultra-violet radiation resisting material, have the not available special optical performance of macrobead, ubiquity " blue shift " phenomenon, extremely strong uv-absorbing, infrared external reflection characteristic are arranged, be added in the coating, can form shielding effect to coating, resistance to deterioration and thermal insulation improve greatly.According to CNS GB9779-88, GB17928-79 and GB67533-86 detect correlated performance of the present invention, and its correlated performance all is improved as can be seen.Shown in the table 1 is the oxygen debt silicon-base oxide SiO of nanometer of different content
