Abstract

The invention relates to the technical field of coatings, in particular to superfine atomized all-weather low-viscosity multipurpose water-based blended water and a preparation method thereof. The water-based blended water is composed of coating resin, n-amyl alcohol, a cosolvent, a base material wetting agent, an auxiliary and the like, the water-based blended water is matched with corresponding metallic paint or plain paint, the practical spray gun air pressure range is wide, the practical temperature and humidity range is wide, and after thinning, the spraying viscosity is low, normal spraying can still be carried out, the arrangement, the surface effect and the like of the metallic paint are not influenced, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an ultra-fine atomized all-weather low-viscosity multi-purpose water-based blended water and a preparation method thereof. [0002] technical background [0003] Coatings are generally composed of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives (such as thickeners). In the process of product production, thickeners are often added to increase the viscosity of the system to a certain range, so that the system can maintain a uniform and stable suspension state or an emulsified state. Viscosity, while spraying, etc. Due to the particularity of water-based paint, the viscosity of the system is often much higher than that of oil-based paint during the production process, so it is necessary to add mixing water during construction. In addition, water-based paint contains a large amount of deionized water. The evaporation heat of water is rel...
