Problems solved by technology

For example, the Chinese invention patents whose authorized announcement number is CN105585928B and authorized announcement number are CN101575478B, the inventive coatings are all organic solvent-based coatings containing certain organic volatile substances. If applied to the wall surface as a protective coating, the cost is relatively high , and will have a certain impact on the environmental protection characteristics, breathability and decorative effect of the original coating
[0008] Based on the above, most of the protective coatings that can be applied to wall decoration coatings and have hydrophobic or scrub-resistant functions are still based on organic solvent-based, water-based or emulsion-based liquid coatings, and the transportation and storage space requirements are relatively low. It is relatively high, and it is difficult to achieve zero discharge of volatile harmful substances while having the function of breathability; water-based and dry powder wall coatings have not really broken through and taken into account organic The technical bottleneck of comprehensive requirements such as volatile matter content, preparation process difficulty and raw material cost

Abstract

The invention relates to hydrophobic breathable inorganic dry powder nanometer protective coating, belonging to the technical field of coating. The coating is prepared by adopting sierozem as an inorganic film forming substance, adopting glass powder as a functional aggregate, adopting nanometer silica, precipitated calcium carbonate and talc powder as modifying fillers, adopting redispersible latex powder as an adhesive, by adopting additives in a certain weight part and through a step of uniform mixing. According to the technical scheme, raw materials are completely inorganic dry powder materials and do not generate organic volatile harmful substances so that environment protection performance is high, transportation and storage costs are low and storage stability is high; a preparationprocess is simple, and a production cost is low; only addition of clear water and mixing are needed for construction so that construction is simple and feasible; a thin transparent protective coatingfilm formed by coating a wall surface requiring protective coatings with the coating has high hydrophobic protection and washable functions, does not influence breathability and decorative effects ofan original coating, and is suitable for wide application in the market; and the coating has comprehensive properties superior to those of other products in the field.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a hydrophobic and air-permeable inorganic dry powder nano protective coating. Background technique [0002] As the country and the government put forward environmental protection policy requirements for the coatings industry, ecological and environmentally friendly coatings have achieved rapid development. Among them, water-based tinted coatings and thick dry powder coatings with high environmental protection characteristics and decorative effects are more widely favored by the market. . At present, the biggest problem encountered in the application of these two types of decorative coatings in the market is that the weather resistance and scrub resistance cannot meet the market demand. For the technical bottleneck, domestic wall paint R&D companies have also begun to explore and solve this problem from multiple angles. [0003] First of all, starting from the technical scheme ...
