The true mineral varnish coating of environmental protection
Technical field
The present invention relates to a kind of coating, more particularly to a kind of true mineral varnish coating of environmental protection.
Background technology
True mineral varnish is the coating that a kind of decorative effect exactly likes marble, granite.The main natural stone for using a variety of colors
Powder is formulated, applied to the imitative stone effect of external wall, therefore also known as liquid stone.
Building after true mineral varnish finishing, has natural real natural colour, gives graceful, harmonious, serious U.S.
Sense, it is suitable for the indoor and outdoor decoration of all kinds of buildings.Particularly decorated on curved-surface building thing, it is vivid, there is a kind of recurrence
Natural effect.True mineral varnish has fire prevention, waterproof, acid and alkali-resistance, anti-pollution.It is nontoxic, tasteless, bonding force is strong, it is will never fade wait spy
Point, can effectively prevent extraneous adverse circumstances from corroding building, extend life-span of building, due to true mineral varnish possess it is good
Adhesive force and freeze-thaw resistance property, therefore be adapted to use in cold district.
The advantages of true mineral varnish:
It is ornamental strong.Natural colour, there is the texture of lithotome, various line lattice designs, various three-dimensional shapes can be provided
Pattern structure, can visually show the elegance of whole building and serious U.S., be dry-fasten stone on external wall best substitute.
It is widely applicable.Available for a variety of basal planes such as cement brick wall, foam, gypsum, aluminium sheet, glass, and can be with building
Any application of moulding.
Aqueous, environmental protective.Asepsis environment-protecting, meet requirement of the people to environmental protection.
Resistance to soiling is good.90% dirt is difficult to adhere to, as bright as new after rain drop erosion, and artificial cleaning is easier.
Service life is grown.The true mineral varnish service life of high-quality is 15 years.
Without potential safety hazard.Exterior wall will load upper kiloton added burden, serious threat to life property using stone material dry suspending.True stone
Paint materials 4-5 ㎏/㎡, only account for the 1/30 of stone material weight, adhesive force is strong, will not image-stone material integrally come off, effective guarantee safety.
