Description
Technical field
The present invention relates to a kind of building coating, it is used for the inorganic pottery of building masonry wall or decorative panel more particularly, to a kind of
Porcelain coating.
Background technology
The exploitation of inorganic architectural coatings is started from after the appearance of phase early 1970s oil crisis with application, market demand
A kind of more economical durable coating.At that time, Japan had successfully researched and developed using silicate inorganic macromolecule as film forming matter first
The coating of matter, the company such as German BASF, Wacker, Bayer and Keimfarben, also successively have developed with special liquid
Potassium silicate is the New Inorganic Paints of main film forming substance.Hereafter, the U.S. is in inorganic coating, inorganic~organic composite coating side
Face there has also been very fast development.Since early 1980s, also there is this kind of successful report of coating research in China, mainly
Using sodium metasilicate, potassium silicate as base-material inorganic coating, and Ludox-styrene-acrylic resin be base-material inorganic coating.
Using alkali silicate as the inorganic coating of base-material, the physical and chemical performance of film, including gloss retention, colour retention, resistance to Huang
Denaturation, heat resistance, freexing tolerance and freeze-thawing resistant cyclicity etc. all preferably, are especially placed in atmospheric environment almost non yellowing for a long time.Together
When, the chemically-resistant and decay resistance of such coating, including resistance to petroleum product, solvent resistance, resistance to household chemical moral character and resistance to
Chemical gases etc..But because alkali metal silicate salt is soluble in water, the maximum that such inorganic coating is used for skin is asked
Topic is exactly that water-resistance property of coating is not good, time long easy-weathering, cracking.Ludox-styrene-acrylic resin is the inorganic coating of base-material, although
In the absence of water resistance it is not good the problem of, but be due to the addition of modified component styrene-acrylic resin in system, make its weatherability not good,
Easy xanthochromia, hardness, chemically-resistant and decay resistance are greatly lowered.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of excellent water resistance, not soft in high humidity environment or water
Change, acid and alkali-resistance and chemical attack, high rigidity inorganic ceramic paint.
The present invention solve its technical problem technical scheme be：A kind of inorganic ceramic paint, components by weight percent that it contains and
Match as Ludox 27~62%, aluminum oxide or hydrated alumina 20~37%, water-soluble hydramine 1~7%, calcium oxide or hydrogen
Calcium oxide 2~13%, pigment 5~16%, HMW polyurethane dispersant 0.5~2%, remaining is water.The present invention to be solved
Technical problem certainly can also be solved further by following technical solution：Water-soluble hydramine is monoethanolamine, diethanol
Amine, triethanolamine, isopropanolamine；Pigment is titanium white, iron oxide yellow, titanium yellow, strontium yellow, chrome yellow, iron oxide red, molybdate red, cadmium red,
Barba hispanica, cobalt blue, chrome green is iron black, carbon black, cobalt violet, zinc powder, aluminium powder, nacreous mica pigment.
Because alkali silicate to exist in the inorganic coating of base-material encounters water after alkali metal ion, film forming again, again
Water can be dissolved in, so must be driven off that stable film could be obtained after alkali metal ion.The present invention is from Ludox as inorganic
The base-material of ceramic coating, because alkali metal ion content measured is extremely low, the problem of water resistance after coating film forming can be avoided.
It is existing because pure silicon colloidal sol easily ftractures (resin aqueous amount is high, and film forming procedure Volume Changes are big) for the coating of base-material
All it is organic resin modification to be used in commercially available Ludox class inorganic coating, most commonly seen is exactly styrene-acrylic resin to be modified.This hair
The solid content of the Ludox of bright selection is high, SiO2Content is more than 40%, and granularity is 10~30nm.If particle diameter is more than 30nm
Or less than 10nm, Ludox in itself and ceramic coating poor storage stability, general one month or so will gel.If
SiO2Content is easily cracked after being less than 40%, coating film forming.
In order to reduce the change of volume in coating film forming procedure, the present invention has been selected in film forming procedure instead can be molten with silicon
Glue reacts and can reduce the material-aluminum oxide or hydrated alumina of Volume Changes as far as possible (such as the production of Pechiney companies of France
Product boehmite).In the paint solidification film forming of the present invention, the contraction of film can be hydrated by tabular alumina or sheet
The use of aluminum oxide, reduces the possibility of crackle generation.Because in tabular alumina or sheet hydrated alumina and Ludox table
Face is all hydroxyl-OH, and they can react to each other and generate Al~O~Si keys, while water outlet is gradually discharged, so as to slow down
The volatilization of water.Meanwhile, when the structure of sheet makes whole system film forming, reduce the Volume Changes therefore produced, reduce crackle
Occur.Can be the oxide of various sheet crystalline state as aluminum oxide or hydrated alumina, such as Alpha-alumina, beta-alumina,
Gama-alumina, δ-aluminum oxide and ε-aluminum oxide etc.；Can also be the hydrated alumina of sheet, the boehmite of such as sheet,
Boehmite and diaspore.Tabular alumina or sheet hydrated alumina surface area are larger, can be with SiO2Occur sufficiently anti-
Should, SiO2With sheet Al2O3Between binding site can be more, while many coating spaces can be reduced.Sheet-shaped alpha-alumina particles
5~50 μm of size, more preferably less than 30 μm.
During present invention solidification, the surface charge disequilibrium of Ludox increasingly generates colloidal sol, carries out polycondensation reaction, finally
Generate three-dimensional consolidated structures.With catalysis form this three-dimensional structure, finally obtain good hardness and water resistance is oxygen
Change calcium or calcium hydroxide.Once small amounts calcium or calcium hydroxide are put into water silica sol, the polycondensation reaction of silica is just
Horse back is understood, so this material can not be directly added into water silica sol and be made for coating.The present invention passes through experiment, hair
Now specific chemical substance can control calcium oxide or calcium hydroxide anti-for Ludox and aluminum oxide or hydrated alumina polycondensation
The speed answered.It was found that water-soluble hydramine can obtain good effect.For this performance of water-soluble hydramine, we
Think, water-soluble hydramine add Ludox after, can with activity Ludox surface hydroxyl (- OH) be complexed, prevent its with
Aoxidize reactive aluminum.So, in film forming curing reaction, calcium oxide or calcium hydroxide must after water-soluble hydramine volatilization,
Could catalysis oxidation aluminium and silicone hydroxyl (Si~OH) reaction, progress polycondensation, final curing film forming.
The present invention can make building or decorative panel reach good decorative effect from the pigment of different colours, meet
The individual requirement of different clients.
The present invention selects HMW polyurethane dispersant, is mainly used in scattered and stable pigments, makes film in storage life
Between be uniformly dispersed, do not reunite.The HMW polyurethane dispersant that can be selected in the present invention can use Afka companies
EFKA4560 HMW polyurethane dispersants.Water in the present invention is decentralized medium.
The present invention can make a variety of construction substrates (such as ceramics, glass, concrete, silicon due to using above-mentioned technical proposal
Calcium plate etc.) there is the coating of good adhesive force, and obtained coating has an excellent rockiness, water resistance, stain resistance,
Resistance to acids and bases, does not burn, and using convenient, can be widely applied to external wall and decorative panel.
