1. Field of the invention:
[001] The present invention relates to a paint, in particular, an inorganic dry powder architectural paint with good resistance to climatic conditions, resistance to cleaning and without refilling and bleaching. 2. Background of the invention:
[002] An architectural paint means a paint used for the exterior wall, interior wall, ceiling or floor of a building for the purposes of decoration, protection and improvement of living conditions. Currently, water-based paint, which appears prominently in the field of paints, contains paint of the type of emulsion in water and paint of the type of solution in water, with water as a dispersion medium. However, the percentage of water in the water-based paint components is up to 35 to 55%, leading to the consumption of a large amount of labor, material resources and financial resources to package or transport the water-based paint. Water. Due to a short shelf and storage life, high cost and special technology are required to solve poor storage stability, ie, avoid separation and thickening during storage.
[003] The discovery of the redispersible powder emulsion by Wacker Chemie AG, Germany, allows the paint to be reduced to a dry powder. Dry powder paint, in general, is a powder obtained from an emulsion by a special process, which changes the way of production and storage, reduces the cost of production, makes packaging and transportation easy and safe, and extends storage time and shelf life. During application, it is mixed with a solvent to form an alcohol-based or water-based paint or quick-drying paint, with advantages such as good adaptability, easy accessibility and savings on some chemical auxiliaries needed in common paint to solve the problem. environmental pollution and save resources. So, dry powder paint has been widely used and developed. Among architectural paint products, dry powder paint with a high solids content was previously invented and has great practical value, such as powder mass, tile powder paint, powder enamel paint, resistant powder paint to water and thermally insulated paint, etc.
[004] A thin layer of dry powder architectural paint is coated, for the most part, by mixing with water and after coating with a roller or coating brush in situ. According to the different requirement of dry powder paint with high solids content, the thin layer of dry powder architectural paint can be divided into two types: one is the pure redispersible powder emulsion system and the other is a composition ( architectural paint of dry inorganic powder) of a redispersible powder emulsion with inorganic powder material, such as plaster, quenched lime, cement, etc.
[005] In the dry powder paint of the pure redispersible powder emulsion system, the property depends mainly on the powder emulsion. The difference in film formation performance between the emulsion and the redispersible powder emulsion leads to a difference in property between the coatings, being extraordinarily evident in the resistance to cleaning, resistance to aging, etc. Therefore, the paint fails in the large scale application.
[006] In inorganic dry powder paint, the inorganic film-forming component, such as cement, lime or plaster, is added, so that the resistance to cleaning and the resistance to aging is greatly improved and advanced. Meanwhile, the dry inorganic powder paint has the advantages of being resistant to frost and being anti-mold, as well as good performance in aspects of resistance to washing with water, adhesion, waterproof, etc. Therefore, in the European market, inorganic dry powder paint has status of great importance. The Chinese patent CN100558834C describes a green powder paint containing redispersible powder emulsion and white cement as the main constituent, in which, it saves many additions commonly used in emulsion paint and reduces the volatile organic compound. Chinese patent CN101230214B describes a dry cement-based powder paint consisting of white cement, redispersible powder emulsion and additions with tile-like and noctilucent functions, with great durability. Chinese patent CN102173710A describes a dry plaster based powder paint comprising plaster powder, white cement and PVA micropowder to solve the poor durability of conventional paint through the chemical bonding reaction.
[007] However, due to the addition of lime or cement and so on, soluble salts will be generated. Soluble salts can separate on the surface of the coating, under certain conditions. These salts are white, so that some lighter colored spots appear on the intense colored coating, which is known as the bleaching phenomenon. Thus, inorganic dry powder paint is only suitable for white or light colored coating. SUMMARY OF THE INVENTION
