Technical field
The invention belongs to energy-saving building technology field, particularly a kind of Graphene double glazing with the function such as energy-conservation being applicable to hot-summer and cold-winter area.
Background technology
Current building or decoration double glazing, the general common white glass that adopts manufactures, although cost is low, its heat-insulating property is not good, and its heat transfer coefficient (K value) is about 3.0.
Also the building had or decoration adopt low-e double glazing, its heat-insulating property is better, heat transfer coefficient (K value) is about 2.4, but it has two shortcomings: when 1, people need sunlight in the winter time, glass is owing to there being LOW-E rete block sunlight, its shading coefficient is below 0.60, and this affects winter heating, is not suitable for being applied to hot-summer and cold-winter area; 2, off-line low-e membrane stability is poor, as easy as rolling off a log oxidized, and double glazing is after the use several years, and low-e film properties is decayed, and its low radiance reduces, and heat-insulating property can decline; Online low-e film antioxidant property is better, but low radiance is poor.
Also the building had or decoration employing three glass two chamber double glazing, its good heat insulating, heat transfer coefficient (K value) is 2.2, and shading coefficient is more than 0.6, and can be applicable to being applied to hot-summer and cold-winter area, its shortcoming is: glass is too heavy, too thick.
Summary of the invention
The object of the invention is to solve weak point of the prior art, a kind of Graphene double glazing is provided.It has multinomial premium properties as described below: have good insulation, heat-proof quality, have higher transmittance; Also can have self-cleaning function, anti-scratch function, be applicable to being applied to hot-summer and cold-winter area.
To achieve these goals, the present invention adopts following two kinds of technical schemes, specifically describes as follows:
A kind of Graphene double glazing, comprise original sheet glass, spacer bar, siccative and seal gum, spacer bar is located between two original sheet glass edge, spacer bar can be the aluminium spacer bar that inner chamber is equipped with siccative, its both sides butyl sealant is bonding with two original sheet glasses, also have second seal gum outside spacer bar, spacer bar can be also hollow composite rubber strip, it is characterized in that: have graphene layer at the surface of internal cavity of former of double glazing.
A kind of Graphene double glazing, comprise original sheet glass, spacer bar, siccative and seal gum, spacer bar is located between two original sheet glass edge, spacer bar can be the aluminium spacer bar that inner chamber is equipped with siccative, its both sides butyl sealant is bonding with two original sheet glasses, also have second seal gum outside spacer bar, spacer bar can be also hollow composite rubber strip, it is characterized in that: have graphene layer at the outside surface of former of double glazing.
Two kinds of Graphene double glazings as above, is characterized in that: described graphene layer thickness is 10nm to 1000nm.
Two kinds of Graphene double glazings as above, is characterized in that: described graphene layer thickness is 30nm to 500nm.
Two kinds of Graphene double glazings as above, is characterized in that: described graphene layer thickness is 50nm to 200nm.
Two kinds of Graphene double glazings as above, is characterized in that: the number of plies of described graphene layer is 1 layer.
Two kinds of Graphene double glazings as above, is characterized in that: the number of plies of described graphene layer is 2 layers.
Two kinds of Graphene double glazings as above, is characterized in that: the number of plies of described graphene layer is 3 layers.
The present invention has the following advantages:
1, good energy-saving effect can be reached.
Because glass of the present invention have employed, double glazing inner chamber original sheet glass surface is provided with graphene layer.This is for the low-e double glazing technology used at present, and the light transmission of Graphene rete, electroconductibility, low diathermaneity, stability will well much than silverskin or other metallic membranes.So double glazing of the present invention is not only good than existing low-e glass properties, and is applicable to hot-summer and cold-winter area because graphene layer has high transmittance.Its high insulating effect, long service life, stable performance.
2, self-cleaning and scratch Be very effective.
Because glass of the present invention also uses, the outside surface of former of double glazing is provided with graphene layer, the advantage of this double glazing is: graphene layer can play the effect of thermal reflecting coating, and heat-proof quality is good, energy-saving effect is obvious; Graphene is good nano material, easily decomposes if it is not easily stained with after ash is stained with ash or dirt, and be easy to wash away totally through rainwater, self-cleaning performance is good; Graphene layer has the hardness also higher than diamond, so the scratch Be very effective of glass.
3, good reliability, long service life.
Because Graphene has extraordinary stability, so no matter it is positioned at the surface of internal cavity of double glazing, or outer surface, its performance does not have any change, good reliability, the long service life of a kind of Graphene double glazing of the present invention in the work-ing life of whole double glazing.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is another kind of structural representation of the present invention.
1,2 be that the Aluminum Hollow spacer bar, 4 that original sheet glass, 3 is equipped with siccative for inner chamber is butyl rubber in figure, 5 TR sealant, 6 and 8 are for graphene layer; 7 is hollow space.
Embodiment
Contrast Fig. 1 is described further a kind of embodiment of the present invention.
