A kind of true mineral varnish coating
Technical field
A kind of coating belongs to wall covering technical field, relates generally to a kind of true mineral varnish coating.
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 there are problems that respective, and 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 give people just
Often life brings influence, exposed wall facing brick has that intensity is high, hardness is high, stability is high, colour-fast easy cleaning the characteristics of, but its consumption
The big exterior wall of energy easily plays drum and comes off, and security is low, other materials such as aluminium-plastic panel light weight, sound insulation, fire prevention, waterproof, weather-proof, construction
It is convenient but with high costs, cannot get extensive popularization and application.
True mineral varnish is applied to exterior wall, and gradually by people receives accreditation.Its is with low cost, and construction technology is simple, can be square
Just it is applied in various building structure, waterproof, the welcome of people has increasingly been received the characteristics of antifouling, weatherability is good.It is existing
True mineral varnish coating screen resilience in the presence of technology is high, water suction discoloration, weatherability are poor, and without thermal insulation.
