Problems solved by technology

[0003] Generally, in order to save energy and protect the environment, the glass curtain wall currently needs better thermal insulation performance, so the structure of double-layer glass panels is adopted, and a gap is left between the double-layer glass panels to make the thermal insulation effect of the glass curtain wall better. Weather, water vapor easily enters between the double-layer glass panels, and after cooling, it is easy to form water droplets. Under the sun, it is easy to breed moss, bacteria, etc. Once moss, bacteria, etc. , will be difficult to clean, so there is room for improvement

Embodiment 1

[0042] A kind of energy-saving glass curtain wall, refer to figure 1 , including several curtain wall units 1 and connecting pieces 2 for installing the curtain wall units 1 .

[0043] refer to figure 2 as well as image 3 , the curtain wall unit 1 includes two parallel glass plates 3, the glass plates 3 are in the shape of a square plate, a sealing strip 5 is clamped between the two glass plates 3, the sealing strip 5 extends along the circumferential direction of the glass plates 3 and is connected end to end, sealed The cross-section of the strip 5 is T-shaped, the sealing strip 5 is partly located between and clamped by the two glass plates 3, the sealing strip 5 part extends outside the glass plate 3 and wraps the peripheral side of the glass plate 3 .

[0044] The two glass plates 3 cooperate with the sealing strip 5 to form a closed curtain wall cavity 4 , and each glass plate 3 is coated with a water-absorbing coating 31 on the surface facing the curtain wall cavit...

Embodiment 2

[0058] The difference from Example 1 is that

[0059] The preparation method of glass plate 3 comprises the following steps:

[0060] a. Add 100kg of polymethyl methacrylate particles, 12kg of glass fiber, 6kg of lotus leaf powder, 4kg of copper powder, and 0.8kg of cobalt salt into the stirring tank at a speed of 60r / min, and stir for 5min to form a mixture evenly.

[0061] b. Put the mixture into a twin-screw extruder and extrude it.

[0062] The copper powder is nano-copper powder with a particle size of 20-25nm;

[0063] The glass fiber length is 0.1-0.2mm.

[0064] The preparation method of water absorbing coating 31 comprises the following steps:

Abstract

The invention relates to the technical field of curtain walls, provides an energy-saving glass curtain wall, and solves the problem that water drops are easily formed between double layers of glass. The technical scheme is as follows: the energy-saving glass curtain wall comprises a plurality of curtain wall units and connecting pieces for installing the curtain wall units. Each curtain wall unitcomprises two parallel glass plates and a connecting frame for connecting the two glass plates; a gap is reserved between the two glass plates. Each curtain wall unit further comprises a sealing stripfilled between the two glass plates, and the sealing strips extend in the circumferential direction of the glass plates and are connected end to end. The two glass plates and the sealing strip are matched to form a closed curtain wall cavity in a surrounding mode, and a water absorption coating is arranged on the plate face, facing the curtain wall cavity, of each glass plate. A gap is reserved between the two glass plates, so that the glass curtain wall is good in heat preservation and heat insulation effect, energy-saving and environment-friendly; when a small amount of external water vaporenters the curtain wall cavity, the water vapor is rapidly absorbed by the water absorption coating, so that the situation that condensed water drops are formed on the surface of the glass plates isavoided, the situation of breeding moss, bacteria and the like is reduced, and the curtain wall cavity is kept clean and does not need to be cleaned.

Description

technical field [0001] The invention relates to the technical field of curtain walls, in particular to an energy-saving glass curtain wall. Background technique [0002] Glass curtain wall refers to the building envelope structure or decorative structure that can have a certain displacement capacity relative to the main structure by the supporting structure system and does not share the force of the main structure. [0003] Generally, in order to save energy and protect the environment, the glass curtain wall currently needs better thermal insulation performance, so the structure of double-layer glass panels is adopted, and a gap is left between the double-layer glass panels to make the thermal insulation effect of the glass curtain wall better. Weather, water vapor easily enters between the double-layer glass panels, and after cooling, it is easy to form water droplets. Under the sun, it is easy to breed moss, bacteria, etc. Once moss, bacteria, etc. , will be difficult to...
