Abstract

The invention belongs to the technical field of buildings, and discloses an energy-saving door and window which comprises a glass body, and a heat insulation coating and a dimming layer are sequentially arranged on the glass body. The heat-insulating coating is prepared from the following components in parts by weight: 50 to 60 parts of epoxy resin emulsion, 20 to 30 parts of graphene heat-insulating slurry, 0.5 to 1 part of a defoaming agent, 1 to 5 parts of a thickening agent, 0.5 to 1 part of a coalescing agent and 0.5 to 1 part of a flatting agent; the dimming layer comprises a substrate, a vanadium oxide layer is arranged on the substrate, a graphene layer is arranged on the vanadium oxide layer, and nano nitrile rubber particles and nano zinc particles are uniformly embedded in the graphene layer. The energy-saving door and window is good in visible light transmission performance and low in cost.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to an energy-saving door and window. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] In recent years, with the development of social economy and the improvement of living standards, people have higher and higher requirements for the comfort of buildings. In the building envelope, doors and windows occupy no less than 10% of the area. The heat transfer coefficient of ordinary glass is significantly higher than that of walls and roofs. [0004] In order to solve the above problems, it is an effective way to install a suitable thermal insulation coating on the building door and window glass. However, the thermal insulat...
