Problems solved by technology

The ratio of glass to window area varies depending on the window frame material, but with the widespread use of glass curtain walls in public buildings and indoor large-area floor-to-ceiling windows in residential buildings, the glass area to window area is becoming larger and larger, The thermal performance of glass affects the thermal performance of the entire window to a large extent, and has a great impact on the comfort of the indoor human body
Ordinary single-layer glass has poor thermal performance such as thermal insulation, and will produce large energy loss during use.
[0003] Chinese patent CN104231832B discloses a thermal insulation coating for architectural glass, which comprises the following components: ATO powder, alcohol-soluble acrylate resin, ethanol, dispersant, leveling agent, defoamer, thickener, Ultraviolet absorber, sodium tetraborate,

Abstract

The invention discloses building glass heat-insulating coating and a preparation method thereof and relates to the field of coatings. The building glass heat-insulating coating comprises, by weight, 18-24 parts of acrylic emulsion, 10-16 parts of waterborne polyurethane emulsion, 1-4 parts of palm oil, 4-7 parts of nano silica, 4-7 parts of nano titania, 2-5 parts of aerogel, 4-7 parts of hollow glass microspheres, 2-5 parts of nano silicon nitride, 2-5 parts of modified zinc oxide, 1-3 parts of an adhesion promoter, 0.2-0.6 part of a defoaming agent, 0.6-1.2 parts of a dispersing agent, and 0.6-1.2 parts of a film-forming aid. The building glass heat-insulating coating made with the synergic materials has good heat insulation, a layer of the coating has good adhesion and good resistance to mechanical impact, and the preparation method has a simple process and is easy to perform.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a heat-insulating coating for architectural glass and a preparation method thereof. Background technique [0002] Among the four enclosure components of doors, windows, walls, roof, and ground that affect building energy consumption, doors and windows have the worst thermal insulation performance, which is one of the important factors affecting indoor thermal environment comfort and building energy consumption. The ratio of glass to window area varies depending on the window frame material, but with the widespread use of glass curtain walls in public buildings and indoor large-area floor-to-ceiling windows in residential buildings, the glass area to window area is becoming larger and larger, The thermal performance of glass affects the thermal performance of the entire window to a large extent, and has a great impact on the comfort of the indoor human body. Ordinary single-layer glass ha...
