Method.
Background technology
As architectural ornament market tends to the decoration theory of " environmentally protective, natural self-contained ", coating variety is also constantly complete
Kind innovation, in recent years, lacquer exactly like lithotome as mark using its decorative effect, mainly natural broken with natural granite etc.
Stone, mountain flour are primary raw material, using synthetic resin emulsion as main binding agent, and are aided with a variety of auxiliary agents and are formulated, meanwhile, true stone
Coating be that its simple production process, construction cost is cheap, ring by up of three layers such as prime coat, lacquer layer and cover enamelled coatings
Guaranteed cost is excellent, has a series of superiority such as fidelity is high, stone texture is strong, decorative strong, safe to use, service life length
Can, reach cheap and good-quality imitative stone decoration effect, become one of leading products of present China's building external paint；At present,
The construction experience deficiency of exterior wall true stone paint, causes the effect that external wall construction goes out not very good, is not reaching to lacquer coating
Perfect decorative effect, main mass defect is thicker for lacquer moisture, if running into dry initial stage rainy, is easy for softening
Whiting, it is also possible to wall facing can be made the even local scaling-off peeling phenomenon in crack occur, therefore, it is necessary to the progress of External Wall lacquer
Further research.
