Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a novel water-based coating containing bentonite and a manufacturing process thereof. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. According to the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings of natural substances or minerals and petrochemical water-based coatings of artificial synthetic resins. [0003] Water-based coatings include water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. Water-based paint refers to the pai...
