In summer, when the outdoor temperature is high and the sun is exposed to intense sunlight, it is placed in a particularly severe environment. If the engine room is placed in a high-temperature environment due to exhaust heat or heat absorption from the outside, the engine output is reduced, resulting in deterioration of fuel consumption and increase of CO2.

  In addition, in the case of a vehicle equipped with a container for cold insulation or heat insulation at the rear, the compressor is operated based on the power from the engine to circulate the refrigerant to keep the inside of the container cold or warm. Is affected by sunlight irradiation heat, and in winter the container is affected by cold air, and the compressor is loaded to maintain the inside of the container at an appropriate temperature, reducing engine output, fuel consumption, CO2 Has brought about an increase.

  Such problems include not only vehicles but also moving bodies such as ships, airplanes, and rockets that generate heat from the built-in power source, and indoor or outdoor equipment that generates heat from the built-in power source, for example, indoors or for home use. Refrigerated refrigerators, air conditioners, outdoor units that receive sunlight irradiation heat, large-scale refrigerated warehouses, vending machines, refrigerated storage boxes for home delivery, power supply units, solar power generation facilities, geothermal power generation facilities, heat exchanger machines, etc. This also applies to the actuating body.

  However, any of the conventional techniques has a problem that it is difficult to apply a heat insulating structure to an existing vehicle, and the manufacturing cost of the vehicle increases with the heat insulating structure.

  The present invention has been made in view of the above problems, and in an operating body such as a vehicle or a device that is operated by a power source, the heat generated by the operation of the power source or external heat is interrupted to improve heat damage. An object of the present invention is to provide a heat-insulating and heat-insulating structure.

  In order to solve the above-described problems, a heat-insulating and heat-insulating structure according to the present invention is a water-soluble heat-insulating structure provided on an outer surface or an inner surface of a part that receives heat generated from a power source and / or a part that receives outside air heat. The first feature is that a heat insulating heat insulating film layer in which a large number of heat shielding pigments and balloon particles are arranged is formed using a heat-resistant resin as a heat shielding binder.

  Power sources include gasoline engines, diesel engines, jet engines, boilers and other internal combustion engines, EVs, electric motors, hydropower, wind power, solar power generation, wind power generation, hydropower generation, geothermal power generation, and the like. Actuators include moving objects (moving objects) such as vehicles, automobiles such as passenger cars, buses, trucks, motorcycles, motorized / assisted bicycles, railway vehicles, construction vehicles, agricultural vehicles, airplanes, ships, rockets, etc. Is included. In addition, the operating body includes installed objects such as outdoor refrigerated warehouses, vending machines, agricultural houses, generators, solar panels for solar power generation equipment, storage battery boxes for wind power generation equipment, geothermal power generation equipment Solids such as heat pipes, indoor or commercial refrigerators / freezers, heat exchanger bodies (outdoor units) equipped with radiators, refrigerated refrigerator-freezer boxes for home delivery, and the like are included.

  The heat generated from the power source includes, for example, heat generated in the engine room by burning gasoline or diesel in an internal combustion engine, heat released from the heat exchange part for an air conditioner into the engine room, and gas generated in the generator. This includes heat generated in the outer box by burning, exhaust heat from the main body, piping, etc., heat generated from the power source in the ship engine room and factory utility equipment, and the like.

  The outside air heat includes irradiation heat from sunlight, reflected heat from the road surface or building wall surface of sunlight, radiant heat, cold air in a cold region, freezing and the like.

  The balloon particles are made of balloon particles such as ceramic, alumina or glass having a specific gravity of less than 1, and are excellent in heat insulation and heat retention. Further, the heat shielding pigment having a specific gravity of more than 1 is made of, for example, titanium oxide or iron chrome, which has an infrared reflection effect, has excellent heat shielding properties, and is excellent in durability. Moreover, since the ceramic or glass-based balloon particles have a water absorption rate of 0.1% or less and have a waterproof function, the waterproof function is imparted to the heat-insulating and heat-insulating film layer.

  According to the heat-insulating and heat-insulating structure according to the present invention, a large number of heat-shielding pigments and balloon particles using a water-soluble resin as a heat-insulating binder are provided on the outer surface or the inner surface of a portion that receives heat generated from a power source in an operating body including a power source. By forming the arranged heat shielding and heat insulating film layers, heat generated from the power source can be shielded to improve heat damage.

  For example, when the operating body having a power source is a vehicle having an engine, the superheater system (turbocharger, supercharger, etc.) is further applied by applying the heat-shielding heat insulating film layer on the outer surface of the air supply pipe in the engine room. ) Is applied to the outer surface of the engine room so that the heat generated in the engine room is shielded by the heat insulating heat insulating film layer, preventing the heating of the air flowing through the air supply pipe and the supercharging system. Reduce output drop.

  In addition, for example, when the operating body having a power source is an outdoor refrigerated warehouse that circulates the refrigerant, by applying the heat insulating heat insulating film layer to the outer surface of the refrigerated warehouse, irradiation from sunlight as outside air heat is performed. Heat and reflected heat are shielded, and the output load of the pump that circulates the refrigerant is suppressed. Furthermore, the heat insulation performance in the case of using as a heat storage is improved by apply | coating the said heat insulation heat insulation film layer to the inner surface of a warehouse.

  Since the heat-insulating and heat-insulating film layer includes a heat-shielding pigment having excellent heat-shielding properties and balloon particles having excellent heat-insulating properties, the heat-insulating and heat-insulating effect can be sufficiently exerted by their combined effect, and the heat damage can be improved.

  The heat-insulating and heat-insulating membrane layer combines heat-shielding pigments and balloon particles with water-soluble resin as a heat-insulating binder, so it has excellent flexibility and follows the bending shape and deformation of the part that receives heat, and these materials are durable Excellent in properties. Therefore, according to the shape of the part which receives heat from the heat-insulating and heat-insulating film layer, the heat-insulating and heat-insulating effect can be maintained for a long time without causing cracks or cracks in the part receiving heat after application.

  The thermal insulation structure according to the present invention has a second feature that the dry thickness of the thermal insulation film layer is 100 to 3000 μm.

  If the dry thickness is less than 100 μm, the heat insulating property is lowered, and if it exceeds 3000 μm, the film thickness strength is insufficient, which causes cracks and cracks. Moreover, the followability with respect to the curved surface and deformation | transformation of the site | part to apply | coat falls. For this reason, the range of 100-3000 micrometers is preferable from the reason of heat insulation, intensity | strength, and followable | trackability.

The thermal barrier heat insulating structure according to the present invention is characterized in that titanium oxide (TiO ₂ ) or iron chromium (Fe—Cr) is used as the thermal barrier pigment having a specific gravity exceeding 1.

  In the construction method of the heat-insulating and heat insulating structure according to the present invention, in the operating body including a power source, the outer surface or the inner surface of the portion that receives heat generated from the power source and / or the portion that receives outside air heat is coated with a water-soluble resin. Apply a kneaded aqueous solution containing a large number of ceramic or glass-based balloon particles and a heat-shielding pigment coated with a water-soluble resin, and dry to apply a water-soluble resin to the outer surface or inner surface of the portion that receives the heat. The first feature is to form a heat-insulating and heat-insulating coating layer in which a large number of heat-shielding pigments and balloon particles are arranged as a heat-shielding binder.

  In the construction method of the heat-insulating and heat insulating structure according to the present invention, in the operating body including a power source, the outer surface or the inner surface of the portion that receives heat generated from the power source and / or the portion that receives outside air heat is coated with a water-soluble resin. A large number of ceramic or glass balloon particles having a specific gravity of less than 1, a combination of ceramic or glass balloon particles having a specific gravity of less than 1 and a thermal barrier pigment having a specific gravity of more than 1 using a water-soluble resin as a binder. Balloon particles and heat-shielding pigments are bonded to the outer or inner surface of the part that receives heat by using a water-soluble resin as a heat-shielding binder on the outer or inner surface of the heat-receiving part. A large number of balloon particles / heat-shielding pigment conjugates are arranged, and a heat-insulating and heat-insulating film layer in which many balloon particles are arranged using a water-soluble resin as a binder on the inner layer The second said Rukoto.

  When constructing a heat-insulating and heat insulating structure, the outer surface or inner surface of the part that receives heat has a large number of ceramic or glass balloon particles with a specific gravity of less than 1 coated with a water-soluble resin, and a specific gravity of 1 using a water-soluble resin as a binder. By applying a kneaded aqueous solution containing a large number of balloon particles / heat shielding pigments combined with ceramic or glass balloon particles less than 1 and a heat shielding pigment having a specific gravity of more than 1, The thermal barrier pigment having a specific gravity of more than 1 floats on the surface layer of the coating layer.

  A thermal barrier pigment with a specific gravity of more than 1 settles according to its weight and does not float on the surface layer of the coating layer by itself, but floats on the surface layer of the coating layer using the buoyancy of the balloon particles. The pigment can be exposed and firmly fixed on the surface. As a result, the heat shielding pigments are arranged on the surface layer of the part after drying, so that construction excellent in heat shielding properties, heat insulating properties, waterproof properties, and heat retaining properties can be performed.

  After the coating layer is dried, the thermal barrier binder holds the bonding state between the balloon particles and the thermal barrier pigment firmly and flexibly, and demonstrates the durability and flexibility of the coating layer. Because it uses water-soluble resin and does not use organic solvent, it is ideal for work environment and safety and health.

  In the construction method of the heat insulating and heat insulating structure according to the present invention, in obtaining a kneaded aqueous solution, the primary kneaded aqueous solution is obtained by kneading 10 to 400 parts by weight of water and 10 to 500 parts by weight of a water-soluble resin with respect to 100 parts by weight of balloon particles. A third characteristic is that the final kneaded aqueous solution is obtained by kneading 1 to 80 parts by weight of the heat shielding pigment with respect to 100 parts by weight of the primary kneaded aqueous solution.

  As described above, according to the heat-insulating and heat-insulating structure according to the present invention, in vehicles, equipment, refrigerated containers, refrigerated warehouses and the like equipped with a power source, the heat-insulating and heat-insulating materials are provided on the outer surface and inner surface of the portion that receives heat generated from the power source. By coating and forming a film layer, and by applying and forming a thermal barrier heat insulating coating layer on the outer surface and inner surface of the part that receives external air heat, the heat generated from the power source is blocked, or the outdoor air heat is blocked, As a result, the output load of the power source can be reduced, the fuel consumption can be prevented from deteriorating, and the increase in CO2 can be prevented.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings. 1 to 4 show a first embodiment of the present invention. In FIG. 1, reference numeral 100 denotes a vehicle.

  As shown in FIG. 1, an engine 102 is disposed in an engine room 101 of the vehicle 100. An intake pipe 105 is connected between the carburetor 103 on the intake side of the engine 102 and the air duct 104. A heat insulating and heat insulating coating layer 10 is formed on the outer surface from the air duct 104 to the intake pipe 105. In addition, a heat insulating and heat insulating coating layer 10 is also formed on the outer surface of the supercharging system (turbocharger, supercharger, etc.) 107.

  As shown in FIG. 2, the heat-insulating and heat-insulating coating layer 10 has a balloon particle / heat-insulating pigment assembly 16 in which the balloon particles 11 and the heat-insulating pigment 13 are bonded to the surface layer portion 10A using the water-soluble resin 12 as a heat-insulating binder. Many balloon particles 11 are arranged in the inner layer portion 10B with the water-soluble resin 12 as a binder.

  The heat-insulating and heat-insulating coating layer 10 is formed on the outer surface from the air duct 104 to the intake pipe 105 and on the outer surface of the supercharging system 107 with a large number of balloon particles 11 coated with the kneaded aqueous solution 17, that is, the water-soluble resin 12. A kneaded aqueous solution 17 containing a large number of balloon particles / heat-shielding pigment assemblies 16 in which the balloon particles 11 and the heat-shielding pigment 13 are bound using the conductive resin 12 as a binder is applied and dried.

  The dry thickness t of the heat-insulating and heat-insulating coating layer 3 is set to 100 to 3000 μm by applying the kneaded aqueous solution 17 once or several times. As shown in FIG. 2, the surface layer portion 10A of the heat-insulating and heat-insulating coating layer 10 has a higher proportion of the heat-shielding pigment 13 than the inner layer portion 10B, and the inner layer portion 10B has a proportion of the balloon particles 11 occupied than the surface layer portion 10A. It is high. A ceramic or glass system having a specific gravity of less than 1 is used for the balloon particles 11, and titanium oxide or iron chromium having a specific gravity of more than 1 is used for the thermal barrier pigment 13.

  In the heat-insulating and heat-insulating coating layer 10, the heat-shielding effect is exhibited by the heat-shielding pigment 13 and the water-soluble resin heat-insulating binder 12 in the surface layer portion 10 </ b> A. Moreover, it heat-insulates by the balloon particle | grains 11 of 10 A of surface layer parts, and the inner layer part 10B, and the heat insulation effect is exhibited.

  The balloon particles 11 are excellent in heat retention and have a waterproof function with a water absorption rate of 0.1% or less, and impart a waterproof function to the heat-insulating and heat-insulating coating layer 10. Thereby, the heat insulating property and waterproofness which were excellent in the vacuum heat insulating material 1 can be provided.

  The heat insulation heat insulation structure of the said structure is constructed as follows.

  First, a kneaded aqueous solution 17 is prepared. As shown in the flowchart of FIG. 3, each material of balloon particles 11, water 14, and water-soluble resin 12 is put into a container of a kneading apparatus, and stirred and kneaded to obtain a primary kneaded material 15. The blending ratio of each material is 50 parts by weight of water and 50 parts by weight of water-soluble resin with respect to 100 parts by weight of balloon particles. Note that water can be appropriately selected from 10 to 400 parts by weight and water-soluble resin from 10 to 500 parts by weight with respect to 100 parts by weight of the balloon particles.

By rotating the stirring plate in the container, the water-soluble resin 12 is coated around each balloon particle 11. The balloon particles 11 are made of ceramic, and use a spherical body of aluminum oxide (Al ₂ O ₃ ) having a particle size of 20 to 60 microns, an average porosity of 10% or more, and a specific gravity of 0.8 or less. When the aluminum oxide is fired at a high temperature of about 1400 ° C., balloon particles having a spherical shape and an average porosity of 10% or more can be stably obtained. An acrylic resin or the like is used for the water-soluble resin 12.

  Next, the heat shielding pigment (titanium oxide) 13 is put into the primary kneaded material 15 in the container, and stirred and kneaded to obtain a final aqueous kneaded solution (secondary kneaded material) 17. The blending ratio at this time is 30 parts by weight of the heat shielding pigment with respect to 100 parts by weight of the primary kneaded product. In addition, a titanium oxide can be suitably selected from 1-80 weight part with respect to 100 weight part of primary kneaded materials.

  When the titanium oxide 13 is introduced later, the water-soluble resin 12 becomes a heat-shielding binder around each balloon particle 11 to bond the heat-shielding pigment 13 to form a balloon particle / heat-shielding pigment combined body 16. Further, the balloon particle / heat-shielding pigment combination 16 may be combined with each other to form a composite unit U. When the total buoyancy of the individual balloon particles 11 exceeds the settling force of the heat shielding pigment 13, the individual balloon particles / heat shielding pigment combined body 16 (or their composite unit) becomes the surface layer of the kneaded aqueous solution 17. Rise to the club.

  Then, the kneaded aqueous solution 17 is applied to the outer surface of the air duct 104 from the air duct 104 to the intake pipe 105 and to the outer surface of the supercharging system 107, whereby the surface layer portion 10A of the coating layer 10 before drying is applied as shown in FIG. A large number of balloon particles / heat-shielding pigment assemblies 16 are floated and arranged, and a large number of balloon particles 11 are arranged on the inner layer portion 10B. After drying, the heat-shielding pigment 13 is fixed so as to be aligned on the surface layer portion 10A.

  After drying, the water-soluble resin 12 firmly holds the bonded state of the balloon particles 11 and the heat-shielding pigment 13 as a heat-shielding binder, and flexibly follows the outer surfaces of the air duct 104 and the intake pipe 105 that are deformed or curved, The durability of the coating layer 10 is exhibited. Furthermore, since the water-soluble resin 12 is used and no organic solvent is used, it is possible to prevent the organic solvent from appearing on the surface layer when the organic solvent is used, thereby inhibiting the original function of the heat-shielding pigment.

  Since the heat-insulating and heat-insulating coating film layer 10 is applied to the outer surface of the air duct 104 and the intake pipe 105 in the engine room 101 and to the outer surface of the supercharging system 107, the heat generated in the engine room 101 due to the operation of the engine 102 is caused. Thermal damage can be reduced. That is, even if heat is accumulated in the engine room 101, the air sucked into the intake pipe 105 from the air duct 104 and the air compressed by the supercharging system 107 are heated by the heat shielding effect of the heat insulating heat insulating coating layer 10. Therefore, heated air is not supplied from the carburetor 103 to the engine 102, and a decrease in the output of the engine 102 is prevented. Therefore, the amount of pedaling of the accelerator does not increase, fuel consumption is not deteriorated, and CO2 is not increased.

  By applying the heat-insulating and heat-insulating coating film layer 10 on both surfaces or one surface of the hood 106 of the engine room 101, the heat-insulating and heat-insulating effect can be further enhanced. That is, by applying the heat-insulating and heat-insulating coating layer 10 on the surface of the bonnet 106, the surface of the bonnet 106 is shielded from sunlight irradiation heat, reflected heat, and radiant heat. Capability reduction and fuel consumption deterioration can be prevented. By applying the heat-insulating and heat-insulating coating film layer 10 on the back surface of the bonnet 106, it is possible to enhance the heat insulation effect, and particularly to shorten the time for warm-up operation in winter, to prevent deterioration of fuel consumption, and to prevent deterioration of battery performance.

  In addition, the heat-insulating and heat-insulating coating layer 10 may be applied to the outer surface or the inner surface of the body of the vehicle 100 to further enhance the heat-insulating and heat-insulating effect. The load on the air conditioner can be reduced.

  The vehicle 100 may be an automobile such as a bus or a truck in addition to the passenger car shown in FIG. 1, and by applying and forming the heat-insulating and heat-insulating coating film layer 10 on the outer surface of the intake pipe in the engine room and the vehicle body, It is possible to reduce engine output load and prevent deterioration of fuel consumption. It can also be applied to motorcycles, motorized / assisted bicycles, railway vehicles, construction vehicles, and agricultural vehicles.

  FIG. 5 shows a second embodiment of the present invention. In the figure, reference numeral 200 denotes a container car for freezing and refrigeration, for keeping warm, and for chilling.

The structure of the heat-insulating and heat-insulating coating layer 10 is the same as that in the first embodiment.

  By applying the thermal insulation heat insulating coating layer 10 on the outer surface of the container 202, the outer surface of the container 202 is shielded from sunlight irradiation heat, reflected heat, and radiant heat, and the thermal insulation thermal insulation coating layer is applied to the inner surface of the container 202. 10 is installed to insulate the cool air in the container 202, and the heat insulation and heat insulation effect reduces the load on the compressor that circulates the refrigerant, reduces the engine output load, deteriorates fuel consumption, and increases CO2. Can be prevented.

  FIG. 6 shows a third embodiment of the present invention. In the figure, reference numeral 300 indicates a vending machine installed outdoors.

  In the vending machine 300 of the present embodiment, a compressor, a refrigerant pipe, and a heat exchanging unit are provided in the outer box 301 for keeping or cooling the beverage can 302 for sale. The outdoor temperature is particularly high in summer, the amount of sunlight is large, and the outdoor temperature is particularly low in winter.
