Description
Technical Field
The present invention relates to a building element.
Background
The existing human-living building has huge energy consumption, the proportion of the building energy consumption in the total energy consumption of human is nearly 40%, the reason is that the heat preservation is insufficient, the wall body heat preservation is not enough, the most serious is a window, a thin layer of glass and a thin layer of glass can not play much of a heat preservation effect at all, the boiler is continuously burnt, the heating radiator continuously heats a room, and the thin window radiates hot air outwards in a calling way (like a person wears a large cotton wadded jacket in cold winter but is open). Secondly, modern buildings almost have no sun-shading measures, sunlight passes through a balcony window to heat a room in summer, and the room can be cooled only by an air conditioner. Statistically, the energy dissipated by a building through a window accounts for about 30% of the energy consumed by the building. Although some existing window bodies are additionally provided with heat-insulating sun-shading shutters, cold and hot bridges of metal door and window frames and the weather resistance of plastic steel door and window frames still need to be solved. The inventor has invented a door and window frame with a hollow microsphere matrix layer and a heat insulation core (Chinese patent No. 202020325917X), but still adopts the existing technology of hollow microsphere heat insulation coating, the existing technology of hollow microsphere heat insulation coating is to mix hollow microspheres in about 9 times of coating and coat on the surface of a workpiece, because the density of the hollow microspheres is much smaller than that of the coating and the hollow microspheres always float upwards, the mixed coating has uneven bead density for a long time, thus causing the coating part to lack beads and failing to form a hollow microsphere three-dimensional matrix layer with the best heat insulation effect and closely arranged hollow microspheres. And the process is complicated due to multiple ingredients, and the cost is increased virtually. In order to solve the problems of lacking of beads in the coating part and complex process caused by the process of the conventional hollow bead heat-insulating coating, the inventor invents a hollow bead matrix layer sticking method (Chinese patent application No. 2020101727663), and the process flow is as follows: firstly, coating viscous paint on the surface of a substrate, (secondly) spraying hollow microspheres on the surface when the paint is not dried and has viscosity, enabling the surface of the substrate to be uniformly adhered with a layer of hollow microspheres, namely a hollow microsphere rectangular layer, by utilizing the viscosity of the paint, (thirdly) after the paint is dried (or aired), coating the paint on the surface layer of the substrate coated with the hollow microspheres, then spraying the hollow microspheres on the surface when the paint is not dried and has viscosity, enabling the surface of the substrate to be uniformly adhered with a layer of hollow microspheres by utilizing the viscosity of the paint, and repeating the working procedure to reach the expected number of hollow microsphere matrix layers, thereby forming a plurality of hollow microsphere matrix layers with closely distributed hollow microspheres, namely a hollow microsphere three-dimensional matrix layer.
Disclosure of Invention
The invention is a technical scheme disclosed for solving the problems of cold and hot bridges of metal door and window frames and the non-weather resistance of plastic steel door and window frames, and the technical scheme of the invention is as follows: thermal-insulated self-cleaning sterilization clean air's that gives sound insulation cavity microballon three-dimensional matrix layer door and window frame, including door and window frame limit 1, cavity microballon three-dimensional matrix layer 2, titanium dioxide anti-radiation membrane 3, characterized in that: the door and window frame edge 1 is coated with a hollow microsphere three-dimensional matrix layer 2, the hollow microsphere three-dimensional matrix layer 2 is a multi-layer closely-arranged hollow microsphere matrix, hollow microspheres are mutually bonded into a whole through viscous paint and are bonded with the door and window frame edge 1, and the surface layer of the hollow microsphere three-dimensional matrix layer 2 is coated with a titanium dioxide anti-radiation film 3. The door and window frame edge 1 can be filled with a heat insulation core 4. In order to reduce the cold and hot bridge effect, the frame edge 1 of the door and window communicated with the indoor and outdoor frame edges can be provided with hollow micro-bead heat insulation strips 5. The door and window frame with the hollow microsphere three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning sterilization and air cleaning preferentially adopts the hollow microsphere matrix layer sticking method (Chinese patent application number: 2020101727663) invented by the inventor to coat the hollow microsphere three-dimensional matrix layer.
The hollow microsphere is a hollow spherical powder-shaped ultra-light inorganic non-metallic new material with excellent performance, the true density of the hollow microsphere is 0.20-0.60/cm, and the particle size of the hollow microsphere is 200-125000 nanometers. The composite material has the characteristics of light weight, large volume, low heat conductivity coefficient, high compressive strength, low oil absorption rate, good dispersibility and fluidity, high chemical stability and the like. It is a high-quality filler for products such as heat-insulating paint, thermosetting plastics, glass fiber reinforced plastics, SMC, artificial stone and the like. The earliest American national aviation and space administration developed a novel hollow microsphere matrix space adiabatic reflective ceramic layer in order to solve the problem of heat transfer control of a space flight vehicle in the 90 s of the 20 th century, the ceramic layer material is composed of a plurality of tiny ceramic hollow microspheres suspended in inert latex, the material is an environment-friendly material with high solar reflectance, high hemispherical emissivity, low thermal conductivity, low heat storage coefficient and other thermal properties, and the adiabatic reflective material is subject to the conversion from the aerospace field to the industry and the construction industry abroad and also is subject to the technical conversion from a thick layer to a thin layer. Are currently finding more and more use in construction and industrial facilities around the world.
The titanium dioxide principle of radiation resistance, self-cleaning, sterilization and air cleaning is as follows: according to different wavelengths, the ultraviolet rays are divided into a short wave region of 190-280 nm, a medium wave region of 280-320 nm and a long wave region of 320-400 nm. Ultraviolet rays in the short wavelength region have the highest energy, but are blocked when passing through the ozone layer, and thus, ultraviolet rays in the medium and long wavelength regions are generally harmful to the human body. The strong ultraviolet resistance of titanium dioxide is due to its high refractive index and high optical activity. When the particle size is larger, the ultraviolet ray is mainly blocked by reflection and scattering, and the ultraviolet ray in the medium wave region and the long wave region is effective. The sun protection mechanism is simple covering, belongs to general physical sun protection, has weak sun protection capability, and can ensure that light can penetrate through the particle surface of titanium dioxide along with the reduction of the particle size, the reflection and scattering of ultraviolet rays in a long-wave region are not obvious, and the absorption of the ultraviolet rays in a medium-wave region is obviously enhanced. The sun protection mechanism is to absorb ultraviolet rays, and mainly absorbs ultraviolet rays in a medium wave region. Therefore, the titanium dioxide has different sun protection mechanisms for ultraviolet rays with different wavelengths, and mainly blocks the ultraviolet rays in a long wave region by scattering, and mainly blocks the ultraviolet rays in a medium wave region by absorbing. The nanometer titanium dioxide has small particle size and high activity, and can reflect and scatter ultraviolet rays and absorb ultraviolet rays, so that the nanometer titanium dioxide has stronger ultraviolet ray blocking capability. The mechanism of absorption of ultraviolet light by titanium dioxide may be: the electron structure of nano-titania is composed of a conduction band formed by a valence band and an empty orbit, and when it is irradiated with ultraviolet rays, light having energy larger than the energy of the forbidden band width (about 3.2 eV) is absorbed, and electrons in the valence band are excited to the conduction band, so that electrons are lacked in the valence band and holes are generated, thereby forming an electron-hole pair which is easy to move and has strong activity. Such electron-hole pairs can, on the one hand, recombine with one another in the event of various redox reactions, release energy in the form of heat or fluorescence, and, on the other hand, can dissociate into free holes and free electrons which migrate freely in the crystal lattice to the lattice surface or to other reaction sites and are immediately captured by surface groups. In general, titanium dioxide is activated by surface water to generate surface hydroxyl groups to capture free holes to form hydroxyl radicals, and free electrons are quickly combined with absorbed oxygen to generate superoxide radicals, so that surrounding bacteria and viruses are killed. The photochemical properties of titanium dioxide have made it useful in many fields, such as air, water and fluid purification. Photocatalysts doped with carbon or other heteroatoms may also be used in sealed spaces or regions with a diffuse light source. When used in coatings for buildings, pedestrian slates, concrete walls or roof tiles, they can significantly increase the decomposition of airborne pollutants such as nitrogen oxides, aromatics and aldehydes. Titanium dioxide, as a catalyst for a pigment of a photo-coating, is not only an environmentally safe cleaning agent, but also has the functions of saving energy and protecting environmental resources. Early scientists in japan and uk coated titanium dioxide on the surface of the paving stones of urban roads to clean the road air. The titanium dioxide may be mixed with the asphalt to reduce pollutants in the air. When the automobile passes by, the concrete or asphalt containing titanium dioxide can purify air and eliminate 25 to 45 percent of nitrogen oxides in the vehicle emissions. When the titanium dioxide is coated on the concrete surface, the air cleaning effect is also obvious.
The invention has the beneficial effects that: the traditional heat-insulating material passively resists heat conduction, and the novel heat-insulating, sound-insulating, self-cleaning, sterilizing and air-cleaning hollow micro-bead three-dimensional matrix layer door and window frame actively cuts off an environmental heat source. Almost all heat transfer modes are heat radiation and heat convection (including diffusion and reflection) before heat flow enters particle space for conduction, the surface layer of the novel heat-insulation, sound-insulation, self-cleaning, sterilization and air-cleaning hollow micro-bead three-dimensional matrix layer door and window frame can obstruct 'atmospheric environment' heat radiation from invading into the enclosure structure, the total heat flow amount obstructed to enter the particle space for conduction is reduced, the hollow micro bead three-matrix layer and the heat insulation core in the door and window frame of the hollow micro bead three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning, sterilization and air cleaning further obstruct the conduction of heat flow entering mass points, obviously reduces the cold and hot bridges of the metal door and window frame, obstructs the heat outside summer from invading indoors, obstructs the heat inside winter from flowing outdoors, and has certain vacuum degree due to the hollow micro beads, therefore, the door and window frame has good sound insulation effect, and the titanium dioxide anti-radiation film has the functions of self-cleaning, sterilization and air cleaning. Therefore, the door and window frame has the functions of heat insulation, sound insulation, self-cleaning, sterilization and air cleaning.

In the figure 1, the inner and outer surfaces of a metal door and window frame edge 1 are respectively coated with a hollow microsphere three-dimensional matrix layer 2 with the thickness of 0.3 mm by adopting the hollow microsphere matrix layer sticking and coating method invented by the inventor, the hollow microsphere three-dimensional matrix layer is a ceramic hollow microsphere matrix layer, ceramic hollow microspheres with the diameter of 200-600 nanometers are coated on the outer layer of the door and window frame edge by adopting a sticking and coating method, the surface layer of the hollow microsphere three-dimensional matrix layer 2 is further coated with a titanium dioxide anti-radiation film 3, and the titanium dioxide anti-radiation film 3 is nano-scale rutile titanium dioxide. The door and window frame edge 1 is filled with a heat insulation core 4. The insulating core 4 here is a non-combustible phenolic foam filled in situ. The phenolic foam is filled in the edges of the door and window frames and is bonded with the edges of the door and window frames into a whole, so that the strength of the edges of the door and window frames is greatly improved or the thickness of the edges of the door and window frames can be reduced. In summer, the heat radiation of the sun can be reflected by the reflection ratio of more than 83 percent outside the door and window frame of the hollow microsphere three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning and sterilization of clean air, and most of the absorbed heat can be emitted by the hemispherical emissivity of more than 87 percent, and the hollow microsphere three-dimensional matrix layer and the heat insulation core in the door and window frame of the hollow microsphere three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning and sterilization of clean air further separate the conduction of heat flow entering mass points, so that the temperature of the outer surface of a building is effectively reduced, and the indoor heat is reduced. In winter, the inner surface of the door and window frame of the hollow micro-bead three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning and sterilization clean air reflects indoor radiant heat back to the room, and radiates the heat on the inner surface of the door and window frame to the room with higher emission ratio, and the hollow micro-bead three-dimensional matrix layer and the heat insulation core in the door and window frame of the hollow micro-bead three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning and sterilization clean air further obstruct the conduction of heat flow entering particles, so that the heat transfer from the room to the outside is reduced. The hollow micro-beads have certain vacuum degree, so the door and window frame has good sound insulation effect. The conventional anti-radiation film is formed by adding nano metal or particles into transparent paint, the nano metal particles form a nano metal particle layer on the surface of a hollow microsphere coating matrix layer, most of solar heat radiation can be reflected like a mirror surface, the glare effect of the mirror surface is avoided, and glare pollution is avoided, so that the radiation of ultraviolet rays to the bonding paint among the hollow microspheres is reduced, the aging speed of the bonding paint is slowed down, and the service life of a door and window frame is prolonged. The titanium dioxide anti-radiation film adopted by the invention is screened by the inventor for a long time through an anti-radiation film comparison experiment, has stronger anti-radiation performance than that of the conventional nano metal anti-radiation film, has the functions of self-cleaning, sterilization and air cleaning, omits the cleaning cost, reduces the transmission of pathogenic bacteria, eliminates 25 to 45 percent of nitrogen oxide in vehicle emissions, and ensures that the living environment of people is healthier. Because good titanium dioxide is expensive and has a high specific gravity, it is recommended to use it only on the surface layer with high density.
In fig. 2, a "hollow bead matrix layer bonding method" is shown, which comprises the following steps: firstly, coating adhesive coating a on the surface of a door and window frame edge 1, (secondly) spraying hollow microspheres on the surface when the coating is not dried and has viscosity, uniformly adhering a layer of hollow microspheres, namely a hollow microsphere rectangular layer b, on the surface of a substrate by using the viscosity of the coating, (thirdly) drying (or airing) the coating, then coating the coating on the surface layer of the substrate coated with the hollow microspheres, then spraying the hollow microspheres on the surface when the coating is not dried and has viscosity, uniformly adhering a layer of hollow microspheres on the surface of the substrate by using the viscosity of the coating, and repeating the procedure to reach the expected number of layers of hollow microsphere matrix, thereby forming a plurality of layers of hollow microsphere matrix layers which are closely distributed, namely a hollow microsphere three-dimensional matrix layer 2. No matter how closely each layer of hollow microsphere matrix is arranged, gaps exist among the microspheres, and the upper layer of microspheres and the lower layer of microspheres can shield the gaps from each other.
In the figure 3, the door and window frame edge 1 is a hollow bead three-dimensional matrix resin door and window frame edge which is made of hollow glass beads and resin with the diameter of 1000 nanometers by adopting a co-extrusion process, the outer surface of the door and window frame edge is coated with a layer of titanium dioxide anti-radiation film 3, the door and window frame edge 1 and the hollow bead three-dimensional matrix layer 2 are combined into a whole, and therefore the heat insulation performance of the door and window frame edge is improved by one layer. And the rheological property of the resin is better after the hollow microspheres are added, the using amount of the resin is reduced, the cost is reduced, the shrinkage rate and the deformation of the product are reduced, the hardness, the rigidity, the wear resistance, the corrosion resistance, the flame retardance, the fire resistance and the sound insulation are improved, and the gnawing of mice and insects (such as termites) is prevented. The heat insulation core 4 filled in the door and window frame edge 1 is aerogel.
In fig. 4, the frame edge 1 of the bridge-cut aluminum door window frame, which is communicated with the inside and the outside of the house, is provided with the hollow bead heat-insulating strip 5, and the heat transfer performance of the hollow bead heat-insulating strip is greatly reduced compared with that of the conventional pure resin heat-insulating strip, so that the cold and hot bridge effect is greatly reduced, and the heat-insulating performance of the frame edge of the door window is greatly improved.
In fig. 5, the hollow bead heat insulating strip is shown in detail, the resin c is mixed into the heat insulating strip extruded from the hollow bead b, the performance is similar to that of the foaming material, the heat insulating performance is at least several times higher than that of the solid resin heat insulating strip, and the amount of the resin is reduced, thereby reducing the material cost, the surface of the hollow bead heat insulating strip is smoother than that of the solid resin heat insulating strip, the insertion of the aluminum profile is easier, thereby reducing the manufacturing cost, and the sound insulating performance, the weather resistance and the mechanical strength are all improved by one block, and the thermal expansion coefficient in the mechanical performance, the yield strength, the elongation and the physical performance of the hollow bead heat insulating strip is very close to and matched with the aluminum alloy.
