Description
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of building wall water-repellent paint.
Background technique
Coating refers to the general name that applied to body surface and can form the material of tough and tensile protective film, and building coating is in coating
An important class will generally be used for inner wall of building in China, exterior wall, ceiling, ground, the coating of toilet is known as building
Build coating.
Building coating has the function of that decoration functions, defencive function and livability are improved.Specific gravity shared by various functions is because making
It is not quite similar with purpose difference.Decoration functions are the functions that its appearance value is improved by the beautification of building.Mainly
Design design and the design of three-dimensional pattern design in terms of including plane color, pattern and gloss.But it will be with building itself
The size and shape of moulding and substrate itself matches, and just can fully play out.Defencive function, which refers to, protects building not
The function of being protected from environmental and destroy.Different types of content required by protective defencive function is also different.Such as
It is indoor just very big with index difference that is reaching required by outdoor coating.Some buildings are to mould proof, fire prevention, insulation, corrosion resistant
Erosion etc. has particular/special requirement.Livability improves function mainly for indoor coating, just contributes to the function for improving living environment
Can, such as sound-proofing, sound absorption properties, anti-condensation.
Conventional wall coating for building primarily serves decorative performance and protective value at present, and interior wall coating is then more focused on
The decorative performance and security performance of coating generally use the better material of film forming to improve the decorative performance of coating, so that
The film layer of coating is finer and smoother uniformly, and blistering or sagging, part high-performance coating in coating process is avoided even to have well
Mirror effect.And security performance then needs to be promoted by the selection to solvent, lotion and function additive, so that coating
Harmful volatile materials is not generated after coating and solidification, avoids causing damages to human health.
Conventional building wall coating all has preferable decorative performance and protective value currently on the market, but adds nothing
The problem that the emulsion paint of machine filler generally has water resistance poor, material under high humility and immersion condition, coating
Film layer is easy water suction bulge, and strength of coating after bulge significantly reduces, and adhesive force is deteriorated, be easy to appear film layer fall off, burn into it is dirty
The phenomenon that dye, so that the decorative performance and protective value of metope substantially reduce.
Number of patent application CN201410537037.8 discloses a kind of nanometer of metope decorative paint, uses titanium white in the coating
The inorganic filler of powder, wollastonite in powder, calcined kaolin and talcum powder as coating, and it is added to nanocomposite, this makes
The intensity for obtaining coating is higher, and ageing-resistant performance is more preferable, and coating is made to have certain bacteriostasis property.But the type coating is resistance to
Water, waterproof performance are still poor, and the coating that coating generates is easy bulge in wet condition, falls off, and lose use value.
Summary of the invention
