Description
Technical Field
The invention relates to the technical field of glass preparation, in particular to hollow glass with a built-in sun-shading device and a preparation method thereof.
Background
The glass is a material with high transparency, strength and hardness and air impermeability, is chemically inert in daily environment and does not react with organisms, so the glass has wide application. In the prior art, glass used for buildings is mainly used for sealing and lighting. However, in winter in cold areas, the heat insulation effect of glass is not ideal, and in summer in hot-summer and cold-winter areas or hot-summer and warm-winter areas, the heat insulation effect of glass is not ideal. Along with the high-speed development of economy in China, the requirements of people on life quality are higher and higher, and doors, windows and glass curtain walls of buildings are larger and larger, so that the proportion of heat exchange through the doors, the windows and the glass curtain walls in heat exchange between the buildings and the outside is higher and higher. In order to reduce the heat exchange through glass doors and windows curtain walls, a plurality of heat insulation glass is developed at home and abroad in recent years, and the glass mainly comprises three types according to the structure: (1) hollow glass composed of two or more layers of ordinary glass; (2) hollow glass formed by glass plated with low-radiation films; (3) the vacuum glass is formed by pumping negative pressure in the middle of double-layer glass. At present, the mainstream energy-saving glass is low-radiation coated hollow glass. The energy-saving glass can prevent partial sunlight from entering the room in summer, but the indoor glare phenomenon still exists, the indoor comfortable luminous environment is influenced, and the indoor lighting capacity is seriously insufficient along with the increase of the capacity of preventing the sunlight from entering the room. Therefore, people have to be assisted by a sun-shading device to further block sunlight from entering the room. However, the conventional sunshade device blocks sunlight and simultaneously causes the reduction of indoor lighting capacity, which is not favorable for indoor lighting. Moreover, with the increasingly strict requirements on energy conservation of buildings in China, the heat insulation performance of the existing heat reflection coated glass and low-emissivity coated hollow glass is increasingly difficult to meet the requirements. Therefore, the development of novel energy-saving glass with higher heat insulation and preservation performance, capability of eliminating indoor glare and high indoor lighting capability is urgently needed.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the hollow glass produced by the preparation method not only has better heat insulation and heat preservation performance and indoor lighting capacity, but also can obtain comfortable indoor light environment, and can be widely applied to the fields of doors and windows, curtain wall glass, lighting roofs and the like of green buildings, ultra-low energy consumption green buildings and near-zero energy consumption green buildings.
The solution of the invention is: (1) the technology of the built-in lighting aerogel is characterized in that the lighting aerogel with excellent heat insulation and heat preservation performance and light transmission performance is built in the inner cavity of the existing hollow glass, and when the sun-shading blades are adjusted to be in a closed state in summer, on one hand, the aerogel can block infrared heat radiation of the ambient temperature, the heat insulation and heat preservation performance of the hollow glass is further improved, and the energy consumption of an indoor air conditioner is greatly reduced; on the other hand, as the lighting aerogel is adopted, the indoor lighting capacity is improved, the direct sunlight can be converted into the diffuse scattering effect, the phenomenon that the existing energy-saving glass is easy to generate glare can be thoroughly eliminated, and the indoor light environment is obviously improved. In winter, the sun-shading blades can be lifted to enable sunlight to directly irradiate and fully absorb heat energy, and can also be adjusted to be in a closed state to block indoor heat from radiating to the outside, so that the indoor heat preservation temperature is greatly increased, and the purposes of saving energy and saving operating cost are achieved. (2) The aerogel and glass or resin composite technology is adopted. The composite board of aerogel and glass or resin, which is manufactured by taking transparent aerogel which is light in weight and has excellent heat insulation and heat preservation performance, sound insulation and noise reduction performance and energy absorption performance as functional components and taking glass or resin as a bonding phase, has the excellent characteristics of aerogel and the good mechanical property of glass or resin, can be directly used as a sun-shading blade to improve the heat insulation and heat preservation performance and the sun-shading effect of hollow glass, and is simpler and more convenient to manufacture.
The solution of the invention is realized by the following steps: the hollow glass with the built-in sunshade device comprises a cavity formed by two transparent plates A and a sealing assembly A and the sunshade device in the cavity, wherein the sunshade device comprises a plurality of sunshade blades, a linkage part and an angle linkage adjusting and lifting device, the sunshade blades are mutually connected through the linkage part and are arranged on the angle linkage adjusting and lifting device, and the hollow glass is characterized in that the sunshade blades comprise a cavity formed by two transparent plates B and a sealing assembly B and aerogel in the cavity.
Therefore, the hollow glass with the built-in sun-shading device is provided with the daylighting aerogel, and the fine nano-network structure of the aerogel effectively limits the propagation of local thermal excitation, so that the hollow glass has extremely low solid heat conduction capability; the nanometer microporous structure inhibits the contribution of gas molecules to heat conduction, so that the convective heat conduction capability is greatly reduced; the refractive index of the silicon-based aerogel is close to l, and the ratio of the annihilation coefficients of infrared rays and visible light reaches more than 100, so that sunlight can be effectively transmitted, and infrared heat radiation of ambient temperature is prevented, therefore, the hollow glass with the built-in sun-shading device adopting the scheme has good heat insulation performance because the aerogel is built in. In addition, due to the arrangement of the lighting aerogel, direct sunlight can be converted into diffuse scattered light, and the glare phenomenon can be greatly eliminated, so that an indoor comfortable internal light environment is obtained, and meanwhile, the indoor lighting capacity is improved. The invention combines the sun-shading device containing the lighting aerogel and the hollow glass into a whole, and realizes the operation of the sun-shading blades by controlling the angle linkage adjustment and the lifting device through magnetic force, thereby saving the use space, simultaneously ensuring that the glass has good sun-shading performance, improving the heat insulation performance of the hollow glass and improving the indoor light environment.
On the basis, the other technical scheme of the invention is that the sunshade blade also comprises a cavity formed by two transparent plates B and a sealing element and aerogel in the cavity. Therefore, the obtained sunshade blade directly uses the sealing element to bond and seal the two transparent plates B, and the manufacturing process is simpler and more convenient.
In another aspect of the present invention, in addition to the above, the sealing member is a thermoplastic resin sheet. Therefore, the thermoplastic resin sheet can be tightly adhered to the two transparent plates after being softened by hot pressing, and the glass cavity can be sealed after being cooled and hardened.
On the basis, the shape of the aerogel can be flat, massive, granular and powder, and is selected according to performance requirements.
The other technical scheme of the invention is that on the basis, the sunshade blade is an aerogel composite board. So, directly regard as the sunshade blade with the aerogel composite sheet to use, can improve cavity glass's thermal-insulated thermal insulation performance and sunshade effect, the preparation is more simple and convenient moreover.
The other technical scheme of the invention is that on the basis, the aerogel composite board is one of an aerogel/glass composite board and an aerogel/resin composite board. Therefore, by adopting the aerogel and glass or resin composite technology, the aerogel and glass or resin composite board manufactured by taking the transparent aerogel which is light in weight and has excellent heat insulation performance, sound insulation and noise reduction performance and energy absorption characteristic as a functional component and taking the glass or resin as a bonding phase has the excellent characteristic of the aerogel and the good mechanical property of the glass or resin.
On the basis, the other technical scheme of the invention is that the preparation method of the aerogel/glass composite board in the aerogel composite board comprises the following steps:
(1) mixing materials, namely uniformly mixing glass powder and aerogel;
(2) melting, namely heating the glass powder in the mixture obtained in the step (1) to be melted to obtain semi-solid mixed glass melt;
(3) molding, namely pouring the mixed glass melt obtained in the step (2) into a mold, and cooling and solidifying;
(4) and (6) annealing.
Thus, through the steps, the aerogel/glass composite board with heat insulation and preservation performance, which is composed of aerogel and glass binding phase, can be obtained. The step (2) in the preparation method can be paving, namely placing the mixture obtained in the step (1) in a mould; then, the step (3) is melting, namely heating the glass powder in the mixture to be melted to obtain semi-solid mixed glass melt, and cooling and solidifying; a clarification process is also included after the melting step and before the forming step; the volume ratio of the aerogel to the glass bonding phase is 0.1-9: 1; the aerogel has the characteristics of internal hydrophobicity and surface hydrophilicity; the shape of the aerogel is one of block, particle and powder.
On the basis, the other technical scheme of the invention is that the preparation method of the aerogel/resin composite board in the aerogel composite board comprises the following steps:
(1) mixing materials, namely uniformly mixing the aerogel and the resin powder;
(2) paving, namely paving a layer of mixture obtained in the step (1) on a mould substrate;
(3) melting, namely rapidly heating the resin powder in the mixture obtained in the step (2) to be molten in a step scanning mode by using a laser;
(4) and (3) alternately spreading and melting, and alternately repeating the step (2) and the step (3) on the previous deposition layer for solidification.
Therefore, through the steps of mixing, paving, heating by a laser and the like, the aerogel/resin composite board with heat insulation and preservation performance, which is formed by aerogel and resin binder phase, can be obtained. Wherein the alternating spreading and melting steps are performed before the resin in the melting step is cured; the alternating spreading and melting step is carried out after the resin in the melting step is solidified; the volume ratio of the aerogel to the resin powder is 0.1-9: 1; the aerogel has the characteristics of internal hydrophobicity and surface hydrophilicity; the shape of the aerogel is one of block, particle and powder; the resin is a thermosetting resin or a thermoplastic resin.
