[0047] B1: chitosan modified by pyridinium quaternary ammonium salt, prepared by the following method:
[0048] (1) Preparation of epoxypyridinium quaternary ammonium salt
[0049] Add 1 mole of epichlorohydrin and 1 mole of pyridine into a completely dry three-necked flask, react at 50°C for 24 hours, filter with suction, and wash the solid product with acetone three times, then dry it in a vacuum oven at 50°C 22h, to obtain epoxypyridinium quaternary ammonium salt;
[0050] (2) Preparation of pyridine quaternary ammonium salt modified chitosan
[0051] In a 100ml three-necked bottle, add 0.1 mole of chitosan and 0.1 mole of the epoxypyridinium quaternary ammonium salt synthesized above, and stir evenly at room temperature; after weighing 0.1 mole of sodium hydroxide and dissolving it in water, add it to the above mixture, After reacting at 60° C. for 10 hours, neutralize with acetic acid and wash repeatedly with ethanol, filter with suction and dry to obtain the chitosan m...

Abstract
The invention discloses an internal wall three-in-one dry powder coating. The internal wall three-in-one dry powder coating is composed of powder and water, wherein the powder and the water are in weight proportion of (1: 0.2)-(1: 0.6); and the powder comprises the following components in parts by weight: natural resin, pyridine quaternary ammonium salt modified chitosan, fiber material, natural clay, calcium carbonate, sulfonated hyperbranched polypyrrolone modified graphene oxide, polybenzimidazole modified meso-porous silicon, KH-560 and inorganic pigment. The internal wall three-in-one dry powder coating has the advantages of being non-toxic and harmless, antibacterial and mould proof, humidity-conditioning and temperature-conditioning, sound-absorbing and noise-reducing, nerve-calming and seepage-proof, capable of adsorbing carbon dioxide, balancing acid-base, producing negative oxygen ions, adsorbing and decomposing formaldehyde, fireproofing and non-inflammable, anti-ageing, anti-radiation, stain-resistant, odor-removing and the like, the continuous growing of the performance and stability of the coating layer can be guaranteed so that the coating layer and the building have the same lifetime; and the coating has strong scientificity, practicability, economy and system integrity.
Description
technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a three-in-one dry powder coating for interior walls. Background technique [0002] Emulsion paint or water paint for building interior walls is made of a large number of chemical emulsions, additives, fillers, and pigments as raw materials. The emulsion is the main film-forming substance, but the molecular structure of chemical emulsion is not very stable: it is difficult to form a film. Membrane additives; if the dispersion is not good, dispersants and defoamers should be added; if the viscosity is not good, thickeners and anti-settling agents should be added; if the covering effect is not good, titanium dioxide and additives should be added; For fear of mildew, fungicides and anti-fungal agents should be added; if the workability is not good, thixotropic agents, leveling agents, and wetting agents should be added; the paint contains a large amou...
