Figure GDA0002645852380000141
From the results in the table two, it can be seen that the aerogel aqueous two-component transparent sound insulation coating prepared in embodiments 1 to 3 of the present invention adopts the phenolic derivative type nonionic hyper-dispersant having the pigment affinity group and the extremely strong anchoring group to perform surface modification on the silica aerogel particles in the comparative ratio 1, and meanwhile, the phosphate anionic dispersant is matched to improve the dispersibility and the easy aggregation characteristic of the silica aerogel powder in the aqueous medium, so that the dispersibility and the stability of the aerogel in the aqueous coating are improved, and the problem of easy aggregation and aggregation of the aerogel is solved. Compared with the comparative proportion 2, because the gamma- (2, 3-epoxypropoxy) propyl trimethoxy silane with the epoxy group in the molecular chain is adopted as the coupling agent to coat the silicon dioxide aerogel particles, the particles are fully crosslinked and reacted with the aqueous polyurethane resin in the drying film forming process, and are chemically bonded with silanol groups on the surface of the glass to form covalent bonds, a firm interpenetrating network three-dimensional crosslinking structure of an organic matrix, a silane coupling agent and an inorganic matrix is formed, the aerogel sound insulation coating is ensured to be firmly attached to the surface of the glass, the problem that the addition of the silicon dioxide aerogel influences the attachment of the coating on the glass is solved, and the durable use effect is ensured. The silane coupling agent adopted in the comparative example 2 is gamma-aminopropyltriethoxysilane, and no epoxy group is provided in the molecular chain, so that silica aerogel cannot be effectively coated, the adhesion to glass is relatively poor, and the paint film adhesion and other properties are affected.
