Description
Technical field
The present invention relates to technical field of coatings, is a kind of exterior wall true stone paint and preparation method thereof specifically.
Background technology
Coating has turned into an important component of building decoration, and at present, external wall decorative material includes TERRAZZO, glass
Glass curtain wall, exposed wall facing brick etc., but these have there is it is respective the problem of, TERRAZZO is easily formed by foreign impacts
Bright line, easy fracture, fire resistance are poor, constructional difficulties, cost are high, although glass curtain wall has good decorative effect, in light
According under the good environment of condition, the strong optical fiber of glass-reflected is mapped in surrounding, not only causes potential safety hazard, and to people just
Often life brings influence, and exposed wall facing brick has the characteristics of intensity is high, hardness is high, stability is high, colour-fast easy cleaning, but it consumes
Can big exterior wall easily play drum and come off, security is low, other materials such as aluminium-plastic panel is light, sound insulation, fire prevention, waterproof, weather-proof, construction
It is convenient but with high costs, it cannot get extensive popularization and application.Decorative paint species is various at present, and the true mineral varnish of artificial granite is rich
The strength of character intension of natural granite, the noble grade of quite aobvious granite, be traditional natural real stone paint new upgrading kind, true stone
Paint has the characteristics that ornamental strong, widely applicable, good endurance, not fugitive color, therefore is a kind of rather well received decoration of exterior wall
Coating.In the construction application of true mineral varnish, the problem of some influence quality, decorative effect often occurs, as coating is too soft, applies
Layer meet water when turning white, spray drop too much etc., there is certain generality.There is tired construction when coating is too thick when using true mineral varnish
Difficulty, too dilute tack then on sand during wall are too low, will all cause sand to drop.
True mineral varnish is applied to exterior wall, and gradually receives accreditation by people.Its cost is cheap, and construction technology is simple, can be square
Just it is applied in various building structure, waterproof, the characteristics of antifouling, weatherability is good have increasingly received the welcome of people.It is existing
With the presence of the true mineral varnish coating screen resilience in technology is high, water suction changes colour, weatherability is poor.
Therefore, in the case of construction is with no difficulty, the denseness of coating is improved as far as possible, contributes to the solution of drop problem.
Emulsion used in true mineral varnish must have good water resistance, bond strength and resistance to ag(e)ing.The MFT of emulsion is not
15-20 DEG C should be less than, its contradiction between construction temperature can solve by coalescents.
