Abstract

The invention discloses a nano-ceramic coating for the thermal insulation of glass. The nano-ceramic coating contains the following components in parts by weight: 30-45 parts of waterborne polyurethane, 10-16 parts of a waterborne alkyd resin emulsion, 5-10 parts of nano-ceramic fibers, 8-16 parts of potassium hexatitanate whiskers, 5-10 parts of nano-ceramic powder, 12-18 parts of nanometer perlite, 3-6 parts of alumina fibers, 1-3 parts of a dispersing agent, 1-3 parts of a thickening agent, 0.2-1 part of a defoaming agent and 15-25 parts of water. The nano-ceramic coating is mainly preparedfrom nano-zirconia, nano-silicon nitride, nano-titanium nitride and nano-zinc oxide. The coating has excellent thermal insulation property and good painting film adhering capacity.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a nano-ceramic coating for glass heat insulation. Background technique [0002] Paint, traditionally called paint in China, is coated on the surface of an object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with the addition of or It is a viscous liquid prepared with organic solvents or water without adding pigments or fillers and adding corresponding additives. Coatings are widely used in people's production and life, and fire-resistant coatings and heat-insulating coatings are one of them. [0003] At present, the main materials used for glass energy saving are: Low-E glass, glass film and heat insulation coating. Low-E glass is mainly used in the field of new buildings and is irreplaceable. Energy-saving materials applied to existing building glass are mainl...
