Description
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of wall coating for building.
Background technology
Coating refers to the general name that can form the material of tough and tensile protective film applied to body surface, 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.Proportion shared by various functions is because making
It is not quite similar with purpose difference.Decoration functions are to improve the function of its appearance value by the beautification of building.Mainly
Design design in terms of including plane color, pattern and gloss and the design of three-dimensional pattern design.But it will be with building itself
The size and shape of moulding and base material itself matches, and just can fully play out.Defencive function refers to protecting building not
Function that is protected from environmental and destroying.Different types of content required defencive function by protective is also different.Such as
It is indoor just very big with index difference that is reaching required by outdoor application.Some buildings are to mould proof, fire prevention, insulation, corrosion resistant
Erosion etc. has particular/special requirement.Livability improves function mainly for indoor application, just contributes to the work(for improving living environment
Can, such as sound-proofing, sound absorption properties, anti-condensation.
Conventional wall coating for building primarily serves decoration performance at present and protective value, interior wall coating are then more focused on
The decoration performance and security performance of coating, in order to improve the decoration performance of coating, the better material of generally use film forming so that
The film layer of coating is finer and smoother uniformly, avoids blistering or sagging in coating process, part high-performance coating is even with good
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 health.
Conventional building wall coating all has preferable decoration performance and protective value currently on the market, but adds nothing
The emulsion paint of machine filler generally with the poor problem of water resistance, 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 susceptible to film layer fall off, burn into it is dirty
The phenomenon that dye so that the decoration performance and protective value of metope substantially reduce.
Number of patent application CN201410537037.8 discloses a kind of nanometer of metope decorative paint, and titanium white is used 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 higher of coating is obtained, ageing-resistant performance is more preferable, and coating is made to have certain bacteriostasis property.But the type coating is resistance to
Water, water resistance are still poor, and the coating that coating generates is easy bulge, falls off in wet condition, loses use value.
