Abstract

The invention relates to an environment-friendly water-based nano-grade titanium dioxide thermal insulation paint and a preparation method thereof. The thermal insulation paint is prepared by stirring the following raw materials, by weight: 25-40 parts of resin synthetic emulsion, 30-40 parts of powders, 3-5 parts of auxiliary agents, 1-2 parts of a thickening agent, and 20-30 parts of water. The powders include nano-grade titanium dioxide powder. Compared with prior arts, a coating formed by the thermal insulation paint is much thinner than that of existing thermal insulation products, and is safer and more environment-friendly than existing products. With the paint, construction cost can be reduced, construction duration can be shortened, and fire is prevented.

Description

Technical field [0001] The invention relates to the preparation of a coating, in particular to an environmentally-friendly water-based nano titanium white thermal insulation coating and a preparation method thereof. Background technique [0002] Chinese patent CN103555097A discloses a thermal insulation coating and its preparation method. Its components are calculated in weight fraction, with 45-60 parts of acrylic copolymer, 10-16 parts of nano titanium dioxide, 5-10 parts of nano silica, 13 -21 parts of glass beads; the heat-insulating coating is prepared by the following steps: (1) Put 10-16 parts of nano titanium dioxide and 5-10 parts of nano silica into a grinder for 15 minutes; (2) mix Add 45-60 parts of acrylic copolymer, 13-21 parts of glass beads, ground nano-titanium dioxide and nano-silica into the container, fully stir for 15 minutes and keep the temperature at 30-50°C; (3) Cool to room temperature at room temperature, That is, the required thermal insulation coatin...
