Abstract
The invention discloses a curing-agent-free inorganic dry powder architectural coating which comprises alkali metal silicate and organic redispersible latex powder and can further comprise a filling material, a pigment and an auxiliary agent. The architectural coating provided in the invention has good storage stability, is convenient for transportation and does not undergo salting-out and whitening nor generate harmful substances like VOC, benzene, formaldehyde and heavy metals after film forming through curing.
Description
Technical field
The present invention relates to a kind of coating, relate in particular to the saltout inorganic powder trade sales coating of albinism of a kind of nothing.
Background technology
Trade sales coating mainly refers to be used for the coating on external wall, interior wall, ceiling, ground etc., has decoration functions, defencive function and inhabitation improvement in performance function.At present trade sales coating is main with water-borne coatings, and water-borne coatings is to be the coating of dispersion medium with water, comprises water miscible liquid and aqueous solution type coating.But water-borne coatings comprises the water up to 35 ~ 55% in forming, and this needs cost great amount of manpower and material resources and financial resources for the packing and the transportation of water-borne coatings; Water-borne coatings quality guaranteed period and shelf lives are short, in order to solve the aqueous architectural coating stability in storage, phenomenons such as layering, thickening do not take place between the shelf lives promptly, also need very high cost and special technology.
Germany Wacker Chemical Co.,Ltd (Wacker Chemie AG) develops redispersable latex powder, coating dry powder is changed into be possible.Dry powder paint generally is that emulsion is become powder through the special process drying, has changed production and banking system, and production cost reduces, packing and convenient transportation, safety, shelf lives and long quality-guarantee period; During use and solvent be made into alcohol radical or water-based paint or quick drying paint, flexibility is strong, and is easy to use; And saved the chemical assistant that must add in the general coating, not only solved problem of environmental pollution, and economized on resources, thereby obtained using widely and developing.In the trade sales coating product, early grow up and what have use value is thick matter dry-type coating, like powdery putty, powdery porcelain-imitated coating, powdery waterproof paint and insulating mold coating etc.
The thin layer dry powder trade sales coating scene of mainly adopting adds roller coat behind the water mixing, the brushing mode is constructed; Therefore require different with thick coating; Thin layer dry powder trade sales coating can be divided into two types at present; One type is the dry powder paint of pure re-dispersible glue powder system, and another kind of is the dry powder paint (inorganic dry powder painting) that inorganic powders such as re-dispersible glue powder and gypsum, white lime, cement are formed.
In the dry powder paint of pure glue powder system; The performance of coating depends on rubber powder to a great extent, but the film forming difference between re-dispersible glue powder and the emulsion causes the performance difference of filming, and outstanding behaviours is in wash-resistant property, ageing-resistant performance etc.; Therefore, this type coating fails to use on a large scale.
Inorganic dry powder painting generally adds inorganic film-forming components such as cement, lime or gypsum; Wash-resistant property and ageing-resistant performance have all had significantly to be improved; Have advantages such as freeze proof, mould proof; And aspects such as washing property of moisture-proof, cohesiveness, water-repellancy all have good performance, and in the European market, this type inorganic powder trade sales coating has occupied the position that attracts people's attention.Like the disclosed green powdered paint of Chinese patent CN100558834C, be staple by redispersable latex powder and white cement, saved the many additives in the rubber-emulsion paint, reduced volatile organic compounds; The disclosed cement-based powder coating of Chinese patent CN101230214B is made up of white cement, redispersable latex powder and the additive that makes coating play imitative porcelain effect and luminous effect, has favorable durability; The disclosed gypsum base inorganic powder of Chinese patent CN102173710A has comprised components such as terra alba, white cement and Z 150PH micro mist, through chemical bond and effect, solves the problem of conventional dry powder coating poor durability.
But above-mentioned inorganic dry powder painting is owing to added lime, cement etc.; Can produce soluble salt, these soluble salts are separated out the surface under certain condition gradually, because these salts have a little white; Make and light spot occurred on the dark coating; Be so-called albinism, therefore, this type of inorganic dry powder painting is only limited to white or light-coloured coating.
