Multifunctional water-based paint and preparation method thereof

Abstract

The invention discloses a multifunctional water-based paint and a preparation method thereof. The preparation method comprises the following steps: adding water to sulfamate, heating, stirring to dissolve the sulfamate, cooling to room temperature, adding water-soluble organophosphate, carrying out idle circulation by a circulating filtering machine, filtering, and storing the filtrate for later use; and respectively milling inorganic silicon and ammonium polyphosphate by a ball mill, putting the inorganic silicon and ammonium polyphosphate into the filtrate, and evenly stirring to obtain the multifunctional water-based paint. After the paint disclosed by the invention is applied onto a thermal insulation material, the flame retardancy time exceeds 60 minutes, the carbonization volume is lower than 5cm<3>, and the limiting oxygen index exceeds 60%. After the paint disclosed by the invention is applied to a polyurethane board twice, the polyurethane board can not be deformed or burnt after being subjected to a high temperature of 300 DEG C for 60 minutes. Since the high-temperature-resistant flame-retardant paint disclosed by the invention has strong heat absorptivity, the paint has a certain inhibition function on the heat transfer of the outside, thereby achieving the effect of heat insulation. When the paint provided by the invention is applied to a thermal insulation material, a temperature difference of 2-5 DEG C can be effectively generated.

Description

technical field [0001] The invention relates to a coating, in particular to a multifunctional water-based coating and a preparation method thereof. Background technique [0002] At present, there are many types of coatings sold on the market. In terms of categories, there are interior wall coatings, exterior wall coatings, special coatings, powder coatings, etc.; There are waterproof coatings, fireproof coatings, anti-corrosion coatings, anti-rust coatings, decorative coatings, etc. There are countless types of brands. [0003] With the development of my country's economy and the improvement of fire protection requirements, especially in the extensive use of surface coatings for building materials, thermal insulation materials, and interior and exterior wall decoration materials, the coating has a single function and its functional indicators do not meet the requirements of the relevant national grades. The phenomenon is obvious, and there are very few products that have com...

[0003] With the development of my country's economy and the improvement of fire protection requirements, especially in the extensive use of surface coatings for building materials, thermal insulation materials, and interior and exterior wall decoration materials, the coating has a single function and its functional indicators do not meet the requirements of the relevant national grades. The phenomenon is obvious, and there are very few products that have comprehensive functions and can ensure their effectiveness, which is far from meeting the needs of social development.
