Description
Technical field
The present invention relates to a kind of antifouling weather-resistant type external wall elastic plucking paint and preparation method thereof, apply and led in building decoration
In domain.
Background technology
Building coating is the essential decoration of building trade, protecting function material, and either indoor or outdoor is all
Coating protection must be carried out.It is indoor to be painted with primary decoration form with flat, and outdoor exterior wall is based on high-decoration building coating.It is high
For ornamental building coating is relatively common plane shallow layer, this kind of coating generally has unique or decoration texture pole
Be plentiful film effect, and it is most of need special construction method and need multiple tracks to construct, can just access and meet the requirements
Film.At present, the high-decoration building coating various types of application, sand textured coating, complex layer coating, galling paint, imitative curtain
Wall coating etc. is the common kind of this kind of coating type.
Exterior coating, exposed to open air, is influenceed, by one section because long-term by daylight, rainwater, dust storm, cold and hot change etc.
After time, facing is susceptible to ftracture, peels off, efflorescence, change colour, fade, the phenomenon such as eclipsed, serious even occurs that wall is opened
Split, cause common problem in the Construction Qualities such as building cracks.Elastic napping coating has protectiveness and dicoration because of it
Dual-use function, can resist the crack of metope, the integrality and the good decorative effect of building of film be kept, by building trade
Approve and like.Its not only performance such as water-fast, alkaline-resisting with generic latex paint, and in range of temperature wider
There are surprising resilience, lasting pliability and excellent elongation, to adapt to the generation and motion in building surface crack, so
And the stain resistance of current external wall elastic galling paint is generally poor, and its weatherability there is also very big problem, by
The actual demand in market cannot gradually be met.
Therefore providing a kind of is possessing elastomeric while having concurrently outside the antifouling weather-resistant type of high dirt resistance power and weatherability
Wall elastomeric gigging paint and preparation method thereof oneself turn into when business urgently.
The content of the invention
For the shortcoming for overcoming existing external wall elastic plucking paint stain resistance, weatherability not good, the present invention provides a kind of resistance to
Antifouling weather type external wall elastic plucking paint and preparation method thereof, it has concurrently excellent while possessing high resiliency covering power performance
Stain resistant and weatherability.
