Abstract

The invention relates to a nano film-forming accelerant for a dry powder coating for interior and exterior walls of a building, and an application of the nano film-forming accelerant, and belongs to the technical field of building coatings. The nano film-forming accelerant comprises the following components in parts by weight: 5-15 parts of methyl propyl trimethoxy silane, 5-12 parts of sodium oxalate and 60-80 parts of nano silica, wherein the particle size of nano silica is 20-200 nm. With the adoption of the nano film-forming accelerant, redispersed emulsion powder particles can be bonded with other components very well and permeate through the surface of a substrate of a building material better. In a coating drying process, volumes of expanded particles are reduced, and then mesh spaces are reduced, so that the contact among molecules is increased greatly, and van der waals interaction forces among the molecules are utilized fully. The dried coating forms a solid film, and is bonded with a wall surface firmly, and a design effect is achieved.

Description

technical field [0001] The invention relates to a nanometer film-forming accelerator for dry powder coatings on interior and exterior walls of buildings, belonging to the technical field of architectural coatings. The cross-linking technology of the nano film-forming accelerator increases the three-dimensional network structure composition of the coating film, thereby greatly improving the compactness of the coating film and enhancing the adhesion of the coating. Background technique [0002] At present, the interior and exterior wall coating products are all in the form of latex. Coatings in the form of latex, in order to transport and store and obtain better construction results, dispersants, antifreeze agents, film-forming aids and co-solvents, etc. are added to the coatings. These chemicals are volatile organic compounds (VOCs) that have a huge impact on human health. VOC is the acronym for volatile organic compounds (the organic compound with a boiling point below 250...
