[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lightweight, heat-insulating and waterproof panel having a heat insulating property and a waterproof property, which is used as a wall material, a roof material, a floor material of a building such as a general building or a house.

[0002]

[Prior art]

 Conventionally, the waterproofing work of a building is done by a sheet waterproofing method in which metal plates or sheets are spread, an asphalt waterproofing method in which a waterproof layer is formed using an asphalt-based material, a mortar method in which mortar is applied, or a synthetic resin waterproof material is applied. There is a method of forming a waterproof coating film.

In any of the above methods, cracks are generated due to deterioration over time due to repeated expansion and contraction due to wind and rain or temperature changes. The occurrence of cracks causes water leakage and also forms a water channel, which is a factor of water leakage expansion. Moreover, these cracks could not be easily found and it was very difficult to repair the leaked water.

Further, since the conventional waterproofing method completely covers the surface to be waterproofed, it may peel or float due to the influence of air, moisture, etc. generated from the surface to be waterproofed. Therefore, there is a problem that a degassing tower must be installed to degas and dehydrate.

[0005] Waterproofing work depends largely on the degree of skill of workers, and for unskilled workers, there is a significant difference in the quality of the work. In addition, there is a problem that it is not possible to work in rainy weather because of the large amount of outdoor construction, which depends on the weather.

[0006]

[Problems to be solved by the device]

 The present invention has been made to solve such a problem, and a foamed resin composition is filled in the space of a core material such as honeycomb produced at the factory, and the front surface or the front and back surfaces of this panel and the peripheral end portion are filled. It is a lightweight insulation waterproof panel with a waterproof layer formed by applying a waterproof coating material to the frame body. By laying this lightweight heat-insulating waterproof panel and filling the joints between the panels with a sealing material, it is extremely easy to perform on-site work such as draining slopes, and there is no concern about the quality of the work due to the difference in the skill of the workers. The purpose of the present invention is to provide a lightweight heat-insulating waterproof panel that can be used immediately in construction, can be used in a waterproof method that can completely prevent water leakage caused by cracks in the coating film, without waiting for hands. I am trying.

[0007]

[Means for Solving the Problems]

 As a result of intensive research aimed at solving such problems, as a result of filling the foaming resin composition into the space of the core material of the honeycomb structure or corrugated structure made of flame-retardant kraft paper and / or non-combustible sheet, the front surface or the front and back surfaces And a light-weight insulation waterproof panel, which is characterized in that a waterproof coating is applied to the peripheral edges to form a waterproof layer.

[0008]

[Action]

 The present invention will be described below. The foamed resin composition is filled in the space of the honeycomb structure or the corrugate structure which is the core material of the panel. The surface or front and back surfaces of the filled core material and the frame bodies at the peripheral edges are coated with a waterproof coating material to make it lighter and have a strong, lightweight insulation and waterproof panel. As the frame body forming the peripheral edge portion, any of inorganic, metal, and organic plate materials or mold materials can be used.

The foamed resin composition includes a resin material to which a foaming agent is added or a resin material to which a foaming agent is added and an inorganic material and reinforcing short fibers are added and filled. The resin material can be foamed by a method using an arbitrary foaming means.For example, a method of adding a foaming agent to foam, or adding a foaming agent to the liquid resin during the polymerization reaction to stir it to foam and the foam disappears. A method of solidifying before forming, a method of generating gas in the polymerization reaction process to form a foamed resin, a method of polymerizing a low boiling point solvent such as propane or butane in the polymerization process to make a molding material, and heating this molding material. Then, the method of foam compression molding can be used.

The resin material used for the foamed resin is thermoplastic resin such as polystyrene, polyethylene, polypropylene, foamed vinyl chloride resin and polyurethane, and thermosetting resin such as phenol, urea, epoxy and hard polyurethane.

The inorganic agent added to and filled in the resin material to which the foaming agent is added can improve the mechanical strength of the foamed resin and can impart flame retardancy and self-extinguishing property to the foamed resin. Inorganic agents include heat-decomposable inorganic agents or inorganic fireproofing agents such as aluminum hydroxide, calcium carbonate, silicon oxide, calcium silicate, magnesium hydroxide, barium sulfate, gypsum, dolomite, talc, clay, mica, antimony trioxide. Powders such as borax and borax can be optionally used.

Organic or inorganic short fibers are added to make the foamed resin composition tough. When organic short fibers are used, vinylon fibers, polypropylene fibers, polyethylene fibers, pulp fibers, etc., which are short fibers in the range of 1 to 20 mm, can be used. However, if impact strength is taken into consideration, vinylon is used. Fibers are more preferably used. When inorganic short fibers are used, glass fibers of 5 mm or less, rock wool, wollastonite, sepiolite, carbon fibers and the like can be used.

When organic short fibers are used, the amount is 8 parts by weight or less based on the total weight of the molded panel. If it is added more than this, the moldability is impaired. It is preferably 0.5 to 5 parts by weight. When organic short fibers and short inorganic fibers are used in combination, the organic short fibers should be in the range of 0.5 to 3 parts by weight and the short inorganic fibers should be in the range of 0.5 to 8 parts by weight. To do. When using only inorganic short fibers without using organic short fibers, the amount is 1 to 10 parts by weight.

As the core material having the honeycomb structure and the corrugated structure, the one formed by the flame-retardant kraft paper and / or the non-combustible sheet is used. As one method of making the kraft paper flame-retardant, the kraft paper immersed in water glass or a suspension of water glass and aluminum hydroxide is dried by hot air at about 100 ° C. Even if the kraft paper that has been subjected to the flame-retardant treatment is ignited, crystal water is generated from the aluminum hydroxide to remove the heat and stop burning. After that, oxidized and dry aluminum remains and the craft paper carbonizes. Further, the state of being coated with water glass can easily carbonize the kraft paper.

When the core material having a honeycomb structure and a corrugated structure is formed of an incombustible sheet, the incombustible sheet used is an inorganic mineral fiber sheet made of calcium silicate or magnesium silicate as a raw material. By using flame-retardant kraft paper or non-combustible sheet as the core material of the lightweight heat-insulating waterproof panel, it is possible to improve the fire resistance as well as the bending strength and impact strength.

[0016] The waterproof layer coating material, which is a waterproof coating material applied to the front surface or the front and back surfaces and peripheral edges of the panel in which the foamed resin composition is filled in the space of the core material, is a waterproof layer using an asphalt-based material, a synthetic material. Either a waterproof layer using a sheet made of rubber or synthetic resin, or a waterproof layer formed by applying or spraying a synthetic resin liquid material with a reinforcing cloth or a mesh attached.

A lightweight heat-insulating waterproof panel in which a waterproof coating is applied only on the surface of the panel to form a waterproof layer is used as an outer wall material / roof material or a floor material of a balcony. It is possible to easily form a drainage gradient of the roof material or the balcony floor material by forming a notch on the back surface of the panel obliquely and laying the panel. Moreover, since the panels have high heat insulation and high water resistance, it is sufficient to fill the joints between the panels with the sealing material for on-site construction.

A lightweight heat-insulating waterproof panel in which the front and rear surfaces of the panel and the frame bodies at the peripheral edges are coated with a waterproof coating material to form a waterproof layer is used for roof waterproofing work, for example. A lightweight heat-insulating and waterproof panel is attached to the surface of the building to be waterproofed using a metal fitting or adhesive, and the joints between the panels are sealed with a sealing material, and if necessary, the top surface of the sealing material is coated with a waterproof material.
