Description

Hollow micro-bead three-dimensional matrix layer shutter for heat insulation, sound insulation, self-cleaning sterilization and air cleaning

Technical Field

The invention relates to a building component.

Background

The existing human-living building has huge energy consumption, the proportion of the building energy consumption in the total human energy consumption is nearly 40 percent, 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 heat preservation effect at all, the boiler is continuously burnt, the radiator continuously heats a room, the thin window exhales hot air outwards in a calling way (like a person wears a large cotton wadded jacket but is open in cold winter)! 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. The heat preservation tripe of certain thickness in the current product solves the heat preservation and the sunshade two problems of window body simultaneously, but the facade of the heat preservation tripe of certain thickness (more than 30 millimeters) has blockked some sunshine and has got into indoor when window body daylighting in winter, not only influences the sight but also has increased the heating expense. The inventor invented a "hollow microsphere coated louver" (Chinese patent No. 2019204228547), but still adopted the existing hollow microsphere thermal insulation coating process, the existing hollow microsphere thermal insulation coating process is to mix the hollow microspheres in about 9 times of coating and coat on the surface of the workpiece, because the hollow microspheres have much lower density than the coating, the hollow microspheres always float upwards, so that the mixed coating is not uniform in bead density from top to bottom after a little long time, thereby causing the coating part to lack beads and failing to form the hollow microsphere three-dimensional matrix layer with the best thermal insulation effect, wherein the hollow microspheres are closely arranged. 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.

The invention is a technical scheme disclosed for solving the problem that a heat-insulating shutter with a certain thickness blocks light from a vertical surface when a window body daylights in winter, and the technical scheme of the invention is as follows: a thermal-insulation sound-insulation self-cleaning sterilization air-cleaning hollow microsphere three-dimensional matrix layer louver comprises a louver substrate 1, a hollow microsphere three-dimensional matrix layer 2 and a titanium dioxide anti-radiation film 3, and is characterized in that: the louver substrate 1 is coated with a hollow microsphere three-dimensional matrix layer 2, the hollow microsphere three-dimensional matrix layer 2 is a plurality of layers of hollow microsphere matrices which are closely arranged, hollow microspheres are mutually bonded into a whole through viscous paint and are bonded with the louver substrate 1, and the surface layer of the hollow microsphere three-dimensional matrix layer 2 is coated with a titanium dioxide anti-radiation film 3. In order to eliminate the gap between the hard blades and improve the heat preservation efficiency, the edge of the louver can be additionally provided with a sealing film 4. The hollow microsphere three-dimensional matrix layer shutter for heat insulation, sound insulation, self-cleaning sterilization and air cleaning preferentially adopts the hollow microsphere matrix layer sticking and coating 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.

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 insulation material passively resists heat conduction, and the novel hollow micro-bead three-dimensional matrix layer shutter for heat insulation, sound insulation, self-cleaning sterilization and air cleaning actively cuts off an environmental heat source. Before heat flow enters particle space for conduction, almost all heat transfer modes are heat radiation and heat convection (including diffusion and reflection), the surface layer of the hollow microsphere three-dimensional matrix layer shutter of the novel heat-insulation, sound-insulation, self-cleaning and sterilization air can prevent 'atmospheric environment' heat radiation from invading the enclosure structure, the total heat flow quantity for preventing the heat flow entering the particle space for conduction is reduced, and the hollow microsphere three-dimensional matrix layer in the hollow microsphere three-dimensional matrix layer shutter of the heat-insulation, sound-insulation, self-cleaning and sterilization air can further prevent the heat flow entering the particle space from being conducted. Experiments prove that: equivalent thermal resistance brought by hollow micro-bead three-dimensional matrix layer shutters of 0.8-2 mm novel heat-insulation sound-insulation self-cleaning sterilization clean air is equal to that of 30-60 mm thick polystyrene boards. The hollow micro-beads have a certain vacuum degree, so the board has a good sound insulation effect, and the titanium dioxide anti-radiation film has the functions of self-cleaning, sterilization and air cleaning. A thin (0.8-2 mm) hollow microsphere three-dimensional matrix layer louver with heat insulation, sound insulation, self-cleaning, sterilization and air cleaning functions is used for replacing a heat preservation louver with a certain thickness (more than 30 mm), the problem that the vertical face of the heat preservation louver with a certain thickness blocks light when the window body is used for lighting in winter is solved, and therefore the contradiction between heat preservation and lighting of the heat preservation louver is perfectly solved. The hollow micro-bead three-dimensional matrix layer shutter for heat insulation, sound insulation, self-cleaning sterilization and air cleaning can be conveniently paved and hung inside and outside a building window body and in an interlayer of multi-layer glass, and the problems of heat preservation, lighting and sun shading of the human residential building window body with huge energy consumption are solved. In addition, the hollow micro-bead three-dimensional matrix layer shutter for heat insulation, sound insulation, self-cleaning sterilization and air cleaning is paved on the top layer and the vertical surface of the multi-span greenhouse, so that the heat preservation and sun shading problems of the multi-span greenhouse with huge energy consumption can be solved.

In the figure 1, the upper and lower surfaces of a 0.18 mm thick louver substrate 1 are respectively coated with a 0.2 mm hollow microsphere three-dimensional matrix layer 2 by adopting the hollow microsphere matrix layer sticking method invented by the inventor, 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. In summer, the heat radiation of the sun can be reflected by the external surface of the louver of the hollow microsphere three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning and sterilization of the air at a reflection ratio of more than 83%, and most of absorbed heat can be emitted out at a hemispherical emissivity of more than 87%, and the hollow microsphere three-dimensional matrix layer in the louver of the hollow microsphere three-dimensional matrix layer for heat insulation, sound insulation, self-cleaning and sterilization of the air further blocks the conduction of heat flow entering mass points, so that the temperature of the external surface of a building is effectively reduced, and the indoor heat is reduced. In winter, the inner surface of the tile plate reflects indoor radiant heat back to the indoor space, meanwhile, the heat on the inner surface of the tile plate is radiated to the indoor space at a high emission ratio, and the hollow microsphere three-dimensional matrix layer in the heat-insulation, sound-insulation, self-cleaning, sterilization and air-cleaning hollow microsphere three-dimensional matrix layer in the hundred leaves further obstructs the conduction of heat flow entering mass points, so that the heat transfer from the indoor space to the outdoor space is reduced. The board has excellent sound insulation effect because the hollow microspheres have certain vacuum degree. The conventional anti-radiation film is formed by adding nano metal or particles into a transparent coating, 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 coating among the hollow microspheres is reduced, the aging speed of the bonding coating is slowed down, and the service life of the plate is prolonged. And the utility model discloses a titanium dioxide anti-radiation membrane that the anti-radiation membrane contrast experiment was carried out to the oneself for a long time and is selected than conventional nanometer metal anti-radiation membrane radiation resistance can be stronger, and has self-cleaning, disinfect, clean air's function, has left out clean expense, has reduced the propagation of germ, has eliminated 25% to 45% nitrogen oxide in the vehicle emission, lets the people live in the environment more healthily. 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.

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 fig. 3, the louver substrate 1 is a hollow microsphere resin plate made of nano hollow microspheres with a diameter of more than 1000 nm and resin, the surface layer is coated with a hollow microsphere three-dimensional matrix layer 2 with a diameter of 200-600 nm, the surface layer of the hollow microsphere three-dimensional matrix layer 2 is coated with a titanium dioxide radiation-resistant film 3, the titanium dioxide radiation-resistant film 3 is nano anatase titanium dioxide, and the rheology is better after the hollow microspheres are added into the resin, so that the use amount of the resin is reduced, the cost is reduced, the shrinkage rate and deformation of the product are reduced, the hardness, rigidity, wear resistance, corrosion resistance, flame retardance, fire resistance and sound insulation are improved, and the biting of mice and insects (such as termites) is.

In fig. 4, the sealing film 4 is additionally arranged on the edge of the shutter of the S-shaped hard heat-insulating sound-insulating self-cleaning sterilizing air-cleaning hollow micro-bead three-dimensional matrix layer, so that the gap between hard blades is eliminated, and the heat-preserving efficiency is improved.

In fig. 5, the hollow micro-bead three-dimensional matrix layer shutters for heat insulation, sound insulation, self-cleaning, sterilization and air cleaning cover the sunny elevation of a building, when sunshine is in winter, the shutters are adjusted to be parallel to the sunshine (the overlook is not influenced), the sunshine is emitted into a window heating room, after the sunshine is removed, the shutters are closed, and the heat preservation room is completely sealed; in summer sunshine, the louvers are adjusted to be perpendicular to the sunshine (the sight distance is not influenced), so that direct sunshine cannot enter a room, and the room can be as cool as a tree under shade, and years of practice prove that: in the area north of the Yangtze river, as long as the heat preservation of the house is qualified, the sunlight cannot be directly emitted into the room from the south window, and the air conditioner can be basically omitted.
