Abstract
The present invention discloses a kind of not containing the inorganic dry powder construction paint of solidifying agent, component comprises alkalimetal silicate and organic redispersible latex powder, filler, pigment and auxiliary agent can also be added, building coating of the present invention has good preservation stability, it is convenient to transport, and after film-forming, there will not be albinism of saltouing, do not produce the objectionable impuritiess such as VOC, benzene, formaldehyde, heavy metal simultaneously.
Description
Technical field
The present invention relates to a kind of coating, particularly relate to a kind of nothing and saltout the inorganic dry powder construction paint of albinism.
Background technology
Building coating mainly refers to the coating for external wall, interior wall, ceiling, ground etc., has decoration functions, protection function and inhabitation performance and improves function. Current building coating is based on water-borne coatings, and water-borne coatings take water as the coating of dispersion medium, comprises water miscible liquid and aqueous solution type coating. But water-borne coatings composition comprise the water up to 35 ~ 55%, this for water-borne coatings packaging and transport, it is necessary to spend a large amount of human and material resources and financial resources; Water-borne coatings quality guaranteed period and shelf lives are short, in order to solve aqueous architectural coating stability in storage, namely the phenomenon such as layering, thickening do not occur, it is also desirable to very high cost and special technology between the shelf lives.
Wacker Chemical Co., Ltd of Germany (WackerChemieAG) develops redispersable latex powder, makes the chemical conversion of coating dry powder for possibility. Dry powder paint is generally that through special process drying, emulsion is become powder, changes production and banking system, and production cost reduces, packaging 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, strong adaptability, it may also be useful to convenient; And save the chemical assistant that must add in general coating, not only solve problem of environmental pollution, and economize on resources, be thus widely used and develop. In building coating product, that relatively early grow up and what have use value is thick matter dry-type coating, such as powdery putty, powdery porcelain-imitated coating, powdery waterproof paint and insulating mold coating etc.
Thin layer dry powder building coating mainly adopts add water mixed even rear roller coat, brushing mode of scene to construct, therefore require different from thick coating, thin layer dry powder building coating can be divided into two classes at present, one class is the dry powder paint of pure re-dispersible glue powder system, and another class is the dry powder paint (inorganic dry powder painting) of the inorganic powder such as re-dispersible glue powder and gypsum, white lime, cement composition.
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 emulsion causes the performance difference of film, and outstanding behaviours is in wash-resistant property, ageing-resistant performance etc., therefore, this kind of coating fails to apply on a large scale.
Inorganic dry powder painting generally adds the inorganic film-forming components such as cement, lime or gypsum, wash-resistant property and ageing-resistant performance have had to be improved significantly, have anti-freeze, the advantage such as anti-mould, and the aspects such as resistance to wet washing property, cohesiveness, water-repellancy all have good performance, in European market, this kind of inorganic dry powder construction paint has occupied the position attracted people's attention. Green powdered paint as disclosed in Chinese patent CN100558834C is main component by redispersable latex powder and white cement, saves the many additives in emulsion paint, decreases volatile organic compounds; Cement-based powder coating disclosed in 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 good weather resistance; Gypsum base inorganic powder disclosed in Chinese patent CN102173710A, includes the components such as terra alba, white cement and polyvinylalcohol microsphere powder, by chemical bond and effect, solves the problem of conventional dry powder coating poor durability.
But above-mentioned inorganic dry powder painting is owing to adding lime, cement etc., soluble salt can be produced, these soluble salts precipitate out surface under certain condition gradually, owing to these salts are slightly white, make that light spot has occurred in dark coating, i.e. so-called albinism, therefore, this type of inorganic dry powder painting is only limited to white or light-coloured coating.

Embodiment 17
In the present embodiment, component comprises:
Lithium silicate 400g;
Ethene/vinylchlorid/lauric acid vinyl acetate terpolymer redispersable latex powder 250g;
Phthalocyanine blue 300g
CaCO3700g

Said components is dry mixed and prepares described inorganic dry powder construction paint, it is added to the water, stir evenly, construction operation can be carried out, the methods such as spraying, roller coat or brushing can be adopted to carry out, the test of stability in storage, workability is carried out according to People's Republic of China (PRC) building trade standard JG/T26-2002 " exterior wall inorganic architectural coatings ", carry out the detection of harmful substance contents according to People's Republic of China (PRC) standard GB/T 18582-2008 " in indoor decorating and refurnishing materials interior wall coating limits of harmful substances ", detected result is respectively in table 1 and table 2.
By table 1 it may be seen that the inorganic dry powder construction paint good rheological property not containing solidifying agent of the present invention, being easy to construction, and time of drying is fast, all has satisfactory stability under heating and cold condition, storge quality is good.
By table 2 it may be seen that inorganic dry powder construction paint of the present invention uses and in construction process, do not produce the objectionable impuritiess such as VOC, heavy metal, benzene, formaldehyde, there is excellent characteristic of environmental protection.
Due to redispersable latex powder one side and alkali metal silicate salt formation uniform organogel-inorganic gel compound system, matrix surface can be more firmly sticked to after making coating curing film forming as binding agent on the other hand, and alkalimetal silicate can't change in use, can not moving to coatingsurface in the resin of solidification, therefore all there is not albinism of saltouing in long-time use procedure in the inorganic dry powder construction paint not containing solidifying agent of the present invention yet.
