At present, the decorative and protective coatings for the inner walls and ceilings of buildings are various, and common decorative coatings such as latex paint, durable protective coatings such as tough glaze paint and inorganic coatings with the characteristic of non-combustion are also available, but the interior decoration materials are non-combustible materials and flame-retardant materials. Since the building uses, places, and locations are different, the surface material for interior decoration is required to be incombustible inorganic paint in many cases. However, the commonly used inorganic coating has decorative effect and protective performance which can not meet the use requirements of users. Therefore, inorganic coatings excellent in decorative effect and protective property are required for interior finishing surface materials.
The inorganic Gui glaze paint is a kind of surface decorative protective paint for building interior, and is one kind of inorganic paint with excellent decorative effect and protective performance. The inorganic carapace glaze coating has the combustion performance grade A1, and is the first choice material for building interior decoration with fire-proof requirement. Meanwhile, the durable decorative protective coating has excellent stain resistance, scratch resistance, solvent wiping resistance, bacteria resistance and mildew resistance, is rich and selectable in color and has excellent environmental adaptability.
CN1513032A discloses a silicone composition for waterproof coating, which discloses a silicone composition comprising (A) a silicone having the general formula (RO)3Si-Q-{(CH3)2SiO}n-(CH3)2Si-Q-Si(OR)3Polydimethylsiloxanes represented by formula (I), wherein R is a C1-C10 monovalent hydrocarbon group, Q is an oxygen atom or a C2-C10 alkylene group, and n is an integer of 10 to 1000; (B) partial hydrolyzates/condensates of alkoxysilanes of the general formula R1xSi(OR2)4-xDescribed wherein R is1Is a C1-C6 monovalent hydrocarbon radical, R2Is C1-C6 alkyl, x is an integer from 0 to 3; (C) an organotitanium-based catalyst; (D) an aliphatic hydrocarbon solvent or an ester-based solvent; and (E) an alcohol-based solvent. The silicone composition disclosed therein can form a soft waterproof film upon curing at low temperature for a short time, but is relatively poor in environmental compatibility and insufficient in hardness.
CN105038335A discloses a normal temperature curing inorganic paint and a manufacturing method thereof, and the raw materials of the disclosed inorganic paint comprise the following components: 70-80 wt% of an inorganic solution; 5-10 wt% of functional auxiliary agent, wherein the functional auxiliary agent is selected from potassium titanate, alumina or a combination of the potassium titanate and the alumina; 10-20 wt% of an inorganic pigment; 0.5-2.0 wt% of other functional additives; the raw materials of the inorganic solution comprise the following components: 30-40 wt% of alkoxy silane, 15-20 wt% of organic solvent and 25-30 wt% of silica sol. The disclosed normal temperature curing type inorganic coating can be cured at normal temperature, does not release organic gas after film forming, and is beneficial to environmental protection, but the disclosed normal temperature curing type inorganic coating cannot solve the contradiction between excellent incombustibility of an inorganic coating, poor comprehensive performance of the coating and limitation of coating environmental adaptability.
In view of the above, it is important to develop an inorganic coating material having both decorative and protective properties and environmental suitability.
