Description
The application is that application No. is 201610209420.X, the applyings date：It is on 04 06th, 2016, entitled " a kind of
The divisional application of the patent of invention of Environment-friendlyexterior exterior wall paint containing oyster shell whiting ".
Technical field
The present invention relates to household chemicals field of coating, are related to a kind of exterior coating, containing shellfish in particular to one kind
The Environment-friendlyexterior exterior wall paint of shell powder.
Background technology
Currently, skin decoration in China's is most also uses the tradition such as granite, mosaic, face brick, aluminium alloy glass
Building materials, not only cost is high for these materials, and has the hidden danger fallen and hurted sb.'s feelings, and is also not easy to safeguard renovation.It is reported that each big city in West Europe
The external wall in city is almost decorated with coating.The ratio for the external wall that Japan and other countries are decorated with coating has been up to 70%~
90%, it defines skyscraper in the national building law such as Singapore, Malaysia and disapproves and decorated using materials such as face bricks.
From now on, China's decorating outer wall of building certainly will walk the road with paint replacement face brick and mosaic material.Currently, China's exterior wall latex paint
In developed and come into operation have it is following several：1, pure acrylic acid emulsion paint；2, the third emulsion paint of silicon, weatherability are better than pure third
Olefin(e) acid emulsion paint；3, aqueous fluorocarbon coating, its weatherability is fine, but price is high；4, solvent type exterior wall coating, weatherability is good,
But it is most of not environmentally.
Oyster shell whiting is by artificial breeding and natural shell by being made after high-temperature calcination, crushing.Its constituent is carbon
The calcified materials such as sour calcium, calcium oxide, calcium hydroxide, this has absorption, decomposes (formaldehyde, benzene, TVOC, ammonia) as cellular
Effect and adjusting air humidity, odor eliminating function.Natural roasting oyster shell whiting, ancient times are known as " clam ash ", before cement appearance, quilt
It is widely used in civil engineering, clam ash is mixed with sticky rice syrup such as, bonding material is made, for viscous between city wall and house wall stone
Knot.Exposed to the weather through 1,100, that is, be used in stone weathering, cured clam ash bonding material still highlights between stone, no
It weathers.Patent document (publication number：CN101774785A a kind of interior wall coating as the main component with oyster shell whiting) is disclosed, it
Using shell calcium carbonate and calcium oxide as main material, using dispersed latex powder as binder, it is added to nano-titanium dioxide and bears
Ion powder has the effect of certain purification air.But the technology by oyster shell whiting for exterior coating has not been reported.
