Abstract
The invention provides an indoor sterilizing inorganic dry powder building coating and a preparation method thereof. The components of the inorganic dry powder building coating include an inorganic cementing material, redispersable rubber power and a sterilizing additive, as well as a general pigment, filler and an additive. The indoor sterilizing inorganic dry powder building coating provided by the invention is a single-component dry powder-like building coating; the coating is added with water in site, uniformly stirred and coated to form a thin decorative coating on the inner wall of a building; by adding a sterilizing agent, the germs on the surface of the coating can be killed for a long time so as to improve the environmental quality of a house; the sterilization property is detected according to the national standard GB/T21866-2008 Antibacterial Coating (Film) Antibacterial Property Measurement and Antibacterial Effect, and the antibacterial rate reaches grade I; meanwhile, the inorganic dry powder building coating disclosed by the invention is good in hiding power and storage stability, convenient to transport and free of generation of any harmful substances such as VOC, benzene, formaldehyde, heavy metals and the like.
Description
Technical field
The present invention relates to a kind of building coating, particularly relate to inorganic dry powder construction paint of a kind of indoor sterilization and preparation method thereof.
Background technology
Building coating mainly refers to, for the coating on external wall, interior wall, ceiling, ground etc., to have decoration functions, defencive function and inhabitation improvement in performance 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 water-soluble sexual type coating.But water-borne coatings forms the water comprised up to 35-55%, this packaging for water-borne coatings and transport, need to spend a large amount of manpower, financial resources and material resources; The water-borne coatings quality guaranteed period and the shelf lives short, in order to solve aqueous architectural coating stability in storage, namely there is not the phenomenon such as layering, thickening between the shelf lives, needing very high cost and special technology yet.
Wacker Chemical Co., Ltd of Germany (Wacker Chemie AG) develops redispersable latex powder, makes that coating is dry powdered becomes possibility.Re-dispersible glue powder is the spray-dried polymer powder obtained of polymer emulsion, again can form stable, that character is substantially identical with former emulsion polymer emulsion with water after mixing by a certain percentage.Relative to liquid emulsion, redispersable latex powder has considerable economic advantages in storage, transport, use.Owing to being coccoid, therefore can be blended in proportion with cement, mineral filler and chemical assistant etc., the powdery work in-process made (add water during use and mix and stir) easy to use, have been widely used in tile paste, external wall heat insulation system, facing mortar, self-flatting ground making level layer, waterproof mortar, cement based powder coating, mending mortar and metope at present and have criticized fields such as scraping material.In building coating product, comparatively early grow up and what have use value is thick matter dry-type coating, as powdery putty, powdery porcelain-imitated coating, powdery waterproof paint and insulating mold coating etc.
Thin layer Dry Powder Architectural Paint mainly adopts scene to add water and mixes rear roller coat, brushing mode is constructed, therefore require different from thick coating, thin layer Dry Powder Architectural Paint can be divided into two classes at present, one class is the dry powder paint of pure re-dispersible glue powder system, the another kind of dry powder paint (inorganic dry powder painting) being the inorganic powder such as re-dispersible glue powder and gypsum, white lime, cement and forming.
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, there is the advantages such as freeze proof, mould proof, and the aspects such as resistance to 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.As Chinese patent CN100558834C discloses a kind of green powdered paint, be main component by redispersable latex powder and white cement, save the many additives in emulsion paint, decrease volatile organic compounds.
