Description
Technical Field
The invention belongs to the field of water-based paint, and in particular relates to an ultraviolet hardening water-based paint and a preparation method thereof.
Background
The water-dilutable coating is a coating prepared by using a post-emulsion as a film-forming material, dissolving a solvent-type resin in an organic solvent, and dispersing the resin in water with the aid of an emulsifier by strong mechanical stirring to form an emulsion, which is called post-emulsion, wherein the prepared coating can be diluted with water during construction. The water-dispersed paint is mainly paint prepared by taking synthetic resin emulsion as film forming matter. The emulsion is a dispersion emulsion formed by dispersing small particle groups polymerized by unsaturated vinyl monomers under a certain temperature condition in water in the presence of an emulsifying agent in the process of mechanical stirring. Coatings formulated by adding a small amount of emulsion to a water-soluble resin cannot be referred to as latex coatings. Water-dilutable coatings cannot be referred to strictly as latex coatings, but are also classically classified as latex coatings.
The water-based paint is classified according to types, and comprises the following components: 1 are classified into a water-reducible type, a colloidal dispersion type, a water-dispersible type or a latex type according to the type of the resin. 2 are classified by drying and curing modes, physical drying, oxidative drying and thermal crosslinking. And 3, classifying according to the application field and the application object of the paint, and classifying into building paint and industrial paint according to the application field. The building paint can be divided into inner wall paint, outer wall paint, ceiling paint, roof waterproof paint, floor paint, etc.
At present, wall cloth and wallpaper are used in indoor decoration, but the wall cloth and wallpaper have the following defects: first, it is not environment friendly. The wall cloth and the wallpaper contain benzene substances, the benzene substances have great harm to human bodies and influence the health of the human bodies, the wall body is required to be coated with oily base oil before the common wall cloth and the wallpaper are pasted, the oily base oil contains solvents, auxiliary agents, auxiliary agent solvents and the like, the substances contain toluene and xylene, serious injury can be caused to respiratory tracts of the human bodies, in addition, wall cloth glue is required to be used when the wall cloth and the wallpaper are pasted, the wall cloth glue contains a large amount of methanol which is a toxic and volatile substance, and the injury to the human bodies is also great. Second, not water resistant: once the climate humidity is high and the environmental condition is poor, the wall cloth and the wallpaper can be wet, thereby causing the phenomena of mildew, falling off, cracking and the like. Third, dirt resistance: the wall cloth and the wallpaper are stuck on the wall body in a sticking mode, so that the wall cloth and the wallpaper cannot be cleaned, and the household cleaning is not facilitated.
The water-based paint has good environmental protection performance, but has a certain difference in functionality compared with the traditional solvent-based paint. Good water resistance and durability are one of the important directions of development of water-based paint. Durability is particularly important for architectural coatings, including weatherability, stain resistance, water resistance, alkali resistance, water resistance, and the like. The coating is exposed in the atmosphere throughout the year, is subjected to weather change all the year round, and is easy to crack, chalking, change color, bubble, fall off, stain and the like under the external effects of cold, hot, oxidation, humidity and the like, so that the coating loses the original decorative effect and the protection function.
In summary, the present invention provides an ultraviolet-curable aqueous coating material and a method for preparing the same, which solve the above-mentioned problems.
