Description
Technical Field
The invention relates to the technical field of doors and windows, in particular to a low-radiation high-heat-insulation glass door and window.
Background
The hollow glass door and window is made of double-layer or multi-layer glass, and between the two layers of glass there is a gap, and in the gap the dry gas is filled. Compared with common glass doors and windows, the hollow glass doors and windows have more excellent heat preservation and sound insulation effects, and are widely applied to occasions needing indoor air conditioning, such as houses, restaurants, hotels, office buildings, schools, hospitals, shops and the like. In some hot areas, especially under the condition of direct sunlight, the heat insulation effect of the common hollow glass door and window is not very ideal, so that the refrigeration cost is increased, the energy is wasted, and the energy-saving effect is poor. At present, the most commonly used heat insulation glass is that the inner glass cavity is filled with gas, so that the glass can play a good heat insulation role for heat generated by outdoor sunlight irradiation, but the temperature of gas in the inner glass cavity is continuously increased due to the continuous irradiation of the sunlight and the concentration of the gas in the inner glass cavity. When the temperature of the gas in the glass inner cavity is increased, on one hand, the pressure of the gas in the glass inner cavity is increased, and the glass or the coating material around the cavity is further extruded, so that the glass is not beneficial to long-term use; on the other hand, the insulating function of the glass against external heat is deteriorated, and the heat insulating function originally possessed by the glass is further lost. Therefore, the glass door and window with high-efficiency heat insulation and long service life is explored and designed, and has an important promotion effect on the further development of door and window technology.
The invention discloses a Low-radiation hollow glass door and window which is disclosed in Chinese patent literature, and the publication number is CN201320458162.0, the invention belongs to the technical field of glass door and window, and particularly relates to a Low-radiation hollow glass door and window which comprises a door and window frame, hollow glass which is filled with argon and is hermetically connected with the door and window frame is arranged in the door and window frame, a hollow aluminum frame is arranged between two glass plates along the edge part, the hollow aluminum frame is respectively bonded with the inner side surfaces of the two glass plates through bonding layers, a molecular sieve is arranged in the hollow aluminum frame, and a plurality of small holes are arranged on the inner wall of the hollow aluminum frame. The Low-radiation hollow glass door and window is made of a Low-E Low-radiation glass plate and a toughened glass plate, argon is filled in the hollow cavity, and the molecular sieve is arranged in the hollow aluminum frame, so that the Low-radiation hollow glass door and window has better heat insulation performance, good sealing performance and dustproof performance compared with the Low-radiation hollow glass door and window made of the existing common glass, and the sound insulation effect is more ideal due to the filling of inert gas.
Its weak point lies in, above-mentioned cavity is airtight cavity, and gas temperature risees the back in the glass inner chamber, can make the gaseous pressure grow in the glass inner chamber, is unfavorable for glass's permanent use, can lead to glass to the isolated function variation of external heat, further loses the thermal-insulated function that glass originally had.
Disclosure of Invention
The invention aims to overcome the problems that the temperature of gas in a cavity of the conventional glass door and window is easy to rise and the heat insulation effect of glass is influenced, and provides a low-radiation high-heat-insulation glass door and window.
In order to achieve the purpose, the invention adopts the following technical scheme:
a low-radiation high-heat-insulation glass door and window comprises a door and window frame, wherein a glass assembly is arranged on the door and window frame, a first cavity and a second cavity adjacent to the first cavity are arranged in the glass assembly, a first gas flow cavity and a second gas flow cavity communicated with the outside are arranged on the door and window frame, a differential pressure air inlet valve and a differential pressure exhaust valve are arranged on the first cavity, the differential pressure air inlet valve is communicated with the first cavity and the first gas flow cavity, and the differential pressure exhaust valve is communicated with the first cavity and the second gas flow cavity; and a LOW-E film coating layer is arranged on the far-light inner side surface of the first cavity.
The glass component is provided with a first cavity and a second cavity which are adjacent, the second cavity is positioned on the high beam side of the glass door and window, and the first cavity is positioned on the low beam side of the glass door and window.

Table 1 items and physical indexes of prepared glass door and window
And (4) conclusion: from the data of examples 1 to 4 and comparative examples 1 to 4, it can be seen that the performance of each parameter of the modified transparent adhesive sandwiched coating layer obtained within the ranges of the filler addition component, the addition content and the preparation sequence protected by the invention is superior to that of the modified transparent adhesive sandwiched coating layer prepared within the parameter range not strictly defined according to the protection range of the invention, and finally the radiation protection performance, the heat insulation performance and the comprehensive mechanical performance of the glass door and window are improved in all directions.
Comparison of the values associated with examples 1-3 and example 4 shows that the thermal insulation and radiation protection properties of the 1mm clear interleaf coating are relatively weaker than those of the 1mm modified clear interleaf coating.
Comparative example 1 differs from example 1 in that 4-tert-butylphenyl salicylate was not added; 4-tert-butyl phenyl salicylate also has intrinsic hydrogen bond in the molecule, after it is irradiated by ultraviolet ray for a certain time, its absorption to ultraviolet ray will increase gradually, until the maximum absorption, because it has been molecular rearrangement under the irradiation of ultraviolet ray, have formed the benzophenone structure with strong ultraviolet absorption ability, can further strengthen its ultraviolet absorption function; the rearrangement of salicylic acid-4-tert-butyl phenyl ester after absorbing ultraviolet rays can enable the arrangement of internal molecular gaps and even micro gaps of the modified transparent doubling coating layer to be tighter, so that the integrity of the transparent doubling coating layer is better, the mechanical and physical properties are better, the related ultraviolet radiation resistance performance can be obviously reduced without adding the components, the compactness of the coating layer can be reduced, and the aging of the modified transparent doubling coating layer can be accelerated.
Comparative example 2 differs from example 1 in that 4,4' -dicyclohexylmethane diisocyanate is replaced by hexamethylene diisocyanate; 4,4' -dicyclohexylmethane diisocyanate has a stable ring structure, has great promotion effect on the large molecular chain space arrangement conformation stability and thermal stability of the whole modified transparent doubling coating layer, and the replacement of hexamethylene diisocyanate increases the shrinkage rate of modified polyurethane, reduces the physical and chemical stability of the modified transparent doubling coating layer, and can not support the performance change impact caused by the rearrangement of the salicylic acid-4-tert-butyl phenyl ester molecular structure, so that the related performance is reduced.
Comparative example 3 differs from example 1 in that no modified nano alumina was added; the modified nano-alumina has a large specific surface area, partial ultraviolet rays entering the transparent doubling coating layer can be scattered at the interface of the modified nano-alumina, most of ultraviolet ray energy is absorbed through electron transition and then released in a vibration heat mode through the recombination of electron-hole pairs, so that the process of shielding the ultraviolet rays is realized, the transparent doubling coating layer is prevented from photo-aging, the internal temperature of the coating film can be reduced due to the scattering and reflection of the modified nano-alumina to the ultraviolet rays, the improvement of the heat insulation performance of the modified transparent doubling coating layer is facilitated, and the filling physical performance and the radiation protection performance of the modified transparent doubling coating layer can be remarkably reduced after the modified nano-alumina is omitted.
Comparative example 4 differs from example 1 in that the nano alumina was not modified; the preparation method comprises the steps of firstly carrying out ultrasonic treatment in deionized water to enable the surface of the nano alumina to be provided with hydroxyl, then adding a tetraisopropanolethanol titanate solution and monoglycerol laurate, wherein the tetraisopropanolethanol titanate solution is grafted with the hydroxyl on the surface of the nano alumina, and the monoglycerol laurate is a typical lipophilic nonionic surfactant, so that the modified nano alumina and the modified polyurethane are compatible and further reacted after being added, the surface of the modified nano alumina contains a large amount of hydroxyl which is convenient to participate in the reaction in the curing process of the modified polyurethane, and finally, the composite coating glue solution with good integrity, high heat insulation performance and strong radiation protection capability is prepared, if the nano alumina is not modified, the compatibility and stability of the nano-alumina are reduced, and part of the nano-alumina is removed, thereby affecting the heat insulation and radiation protection performance.
As can be seen from the data of examples 1-4 and comparative examples 1-4, only the scheme within the scope of the claims of the present invention can satisfy the above requirements in all aspects, and the preparation scheme of the modified transparent laminated rubber coating layer and the glass door and window frame with excellent comprehensive performance can be obtained. The change of the mixture ratio, the replacement/addition/subtraction of raw materials or the change of the feeding sequence can bring corresponding negative effects.
The raw materials and equipment used in the invention are common raw materials and equipment in the field if not specified; the methods used in the present invention are conventional in the art unless otherwise specified.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
