A kind of energy-saving vacuum glass
Technical field
The present invention relates to a kind of vacuum glass, be specifically related to a kind of energy-saving vacuum glass.
Background technology
Mankind's energy total amount that building consumes is increasing, account for the 5%-20% of mankind's business total energy consumption at present, the door and window hole of building is then energy-conservation weak link, the energy that building is in use consumed has nearly half to be run off by door and window, glass is as the main material of door and window structure, and its energy-conservation character draws attention day by day.
CN101725306A disclosed on 06 09th, 2010 a kind of energy-efficient, insulation vacuum glass, comprise at least two layers of glass, key is provided with the obtained support column of some transparent materials between two layers of glass, adhesive seal material is had between the marginal gap of two layers of glass, the first wall between two layers of glass is vacuum state, but, owing to designing the deficiency of upper existence, its energy-saving effect is desirable not enough, is difficult to meet social development demand.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of energy-saving effect better energy-saving vacuum glass.
The technical solution adopted for the present invention to solve the technical problems is: a kind of energy-saving vacuum glass, comprise the first glassy layer and the second glassy layer, the surrounding of described first glassy layer and the second glassy layer is bonded as integrative-structure by adhesive seal material, wall between described first glassy layer and the second glassy layer is vacuum state, in the wall of described first glassy layer and the second glassy layer, be provided with heat insulating coat on the surface of the second glassy layer.
Further, described heat insulating coat is prepared from by following methods: first by polyvinyl alcohol rubber powder, tin indium oxide, hollow glass microballoon in mass ratio for the ratio of 2:4-6:2-4 mixes, obtain compound, then the ratio being 1.5-2.5:1 in mass ratio by gained compound and water stirs, obtain insulating moulding coating, again gained insulating moulding coating is covered the surface of the second glassy layer in the mode sprayed or brush, dry.
Further, described hollow glass microballoon is the hollow glass microballoon of particle diameter 30 ~ 50 microns.
Further, the thickness of described heat insulating coat is 0.5-3.0mm.
Further, in the wall of described first glassy layer and the second glassy layer, be provided with support member, with the anti-pressure ability of reinforcing glass, the thickness of wall can be adjusted according to the thickness of support member simultaneously.Described support member is made up of transparent material.
Further, the surrounding of described first glassy layer and the second glassy layer is also provided with weather strip.
Further, described adhesive seal material is the high strength such as silica gel or butyl rubber cohesive material.
Structure of the present invention is simple, and processing and manufacturing is easy, and after testing, hot merit K value coefficient can reach 0.3W/ (m
2k), its hot property is far superior to existing vacuum glass, more energy-conservation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to Fig. 1, the present embodiment comprises the first glassy layer 1 and the second glassy layer 2, the surrounding of described first glassy layer 1 and the second glassy layer 2 is bonded as integrative-structure by adhesive seal material 3, wall between described first glassy layer 1 and the second glassy layer 2 is vacuum state, in the wall of described first glassy layer 1 and the second glassy layer 2, be provided with heat insulating coat 4 on the surface of the second glassy layer 2.
In the present embodiment, described heat insulating coat 4 is prepared from by following methods: first by polyvinyl alcohol rubber powder, tin indium oxide, hollow glass microballoon in mass ratio for the ratio of 2:5:3 mixes, obtain compound, then the ratio being 2:1 in mass ratio by gained compound and water stirs, obtain insulating moulding coating, again gained insulating moulding coating is covered the surface of the second glassy layer in the mode of spraying, dry.Described hollow glass microballoon is the hollow glass microballoon of particle diameter 30 ~ 50 microns.The thickness of described heat insulating coat 4 is 1.5mm.
In the present embodiment, be provided with support member 5 in the wall of described first glassy layer 1 and the second glassy layer 2, with the anti-pressure ability of reinforcing glass, described support member 5 is made up of transparent material.
In the present embodiment, the surrounding of described first glassy layer 1 and the second glassy layer 2 is also provided with weather strip 6.
In the present embodiment, described adhesive seal material 3 is silica gel, certainly, also can be the high strength cohesive materials such as butyl rubber.
After testing, the hot merit K value coefficient of the present embodiment is 0.3W/ (m
2k), its hot property is far superior to existing vacuum glass, more energy-conservation.
