Problems solved by technology

There are also people who add nano-components to improve the quality of coatings. For example, the invention patent No. 03118030.2 uses pure acrylic emulsion as the base material and adds nano-scale zinc oxide, silicon oxide and titanium oxide. Scrub resistance, antibacterial and self-cleaning functions, but the thermal insulation effect is poor, and the production process is more complicated

Embodiment 1

[0025] Embodiment 1: Determining the mass percentage composition of aluminum silicate nanocomposite thermal insulation coating is as follows: nano aluminum silicate 15%, vinegar acrylic emulsion 25%, water 41%, nano silica 6%, nano alumina 3%, nano oxide 3% zinc, 3% nano-titanium oxide, 0.5% film-forming aid, 1% defoamer, 1% wetting and dispersing agent, 1% antifreeze, and 0.5% leveling agent. The preparation process is as follows: Stir water, nano-aluminum silicate, wetting and dispersing agent, and half of the defoamer at high speed for 2 hours under low-speed stirring to fully disperse them, then add other inorganic nano-powders under stirring, and disperse Stir at high speed on the machine for 3 hours, and disperse it evenly by high-speed shearing. Then slowly add the emulsion dropwise at a low stirring speed, then add the remaining defoamer, film-forming aid, antifreeze, and leveling agent and stir for 3 hours at a low speed, and finally pack into a can to obtain the fini...

Abstract

The invention discloses an aluminium silicate nano composite insulation coating and a preparation method thereof. The composite insulation coating comprises the following components of 10 to 40% of nano aluminium silicate, 15 to 30% of vinegar acrylic emulsion or acrylic emulsion, 30 to 50% of water, 2 to 6% of nano silicon dioxide, 2 to 6% of nano aluminum oxide, 2 to 5% of nano zinc oxide, 2 to 5% of nano titanium oxide or titanium white, 0.1 to 2% of film forming assistant, 0.1 to 2% of defoaming agent, 0.1 to 2% of wet dispersing agent, 0.5 to 2% of antifreeze and 0.1 to 2% of flatting agent. The preparation method comprises the following steps of stirring the water, the nano aluminium silicate, the wet dispersing agent and a half of the defoaming agent at high speed in a low speed stirring mode to be fully dispersed; adding other inorganic nano powder in the course of stirring; stirring on a multi-function disperser at high speed; slowly adding the emulsion at low stirring speed; adding the rest defoaming agent, the film forming assistant, the antifreeze and the flatting agent to be stirred at low speed; and finally canning to prepare the finished coating product. The invention can ensure that the surface of building materials is coated with a layer of coating of the thickness lower than 1mm; the heat conductivity coefficient of the building materials coated with the coating is reduced by 0.07 W/m.K when the temperature is 100 DEG C relative to the building materials without the coating.
