Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-weight, water-insulating surface having excellent heat-insulating properties and excellent rigidity for use as walls, roofs, rooftops, balconies, floors and the like of buildings such as general buildings and houses. Of the underlayer gradient plate.

[0002]

2. Description of the Related Art Conventionally, as a base gradient plate for forming a water gradient surface of a roof, a synthetic resin foam molded article is formed by extrusion foaming, and then the synthetic resin foam molded article is cut into a predetermined shape and size by using a hot wire. The surface was cut diagonally in the horizontal direction, and the diagonally cut surface was used as a water gradient surface.

[0003] Further, an original sheet of synthetic resin foam board extruded and extruded by an extruder is cut obliquely using a band saw which crosses the traveling direction obliquely, and two water gradient surfaces are used for two gradient plates. It is also used as a base plate.

However, in any of the methods, since the base gradient plate made of a synthetic resin foam molded article is a synthetic resin foam molded article, it has low compressive strength and is easily chipped at its ends. For this reason, in normal construction where a non-combustible plate is attached to the upper surface and waterproofing is performed, the expansion ratio of the synthetic resin foam molded product is maintained in order to maintain the compressive strength of the synthetic resin foam molded product and the strength at which the ends are not chipped. Had to be reduced considerably, and the material cost was relatively high.

However, in actuality, the expansion ratio cannot be reduced so much from the viewpoint of material cost, and generally the expansion ratio is about 30 to 50 times, so that chipping at the end cannot be completely prevented.

Means for Solving the Problems As a result of diligent research for solving such problems, a foamed resin composition is filled in a space of a core material having a honeycomb structure or a lattice structure made of a synthetic resin with a gradient, and lightweight insulation is provided. The problem has been solved by a water-graded ground plate which is characterized by forming a panel.

[0008]

The present invention will be described below. A foamed resin composition is filled in a space of a honeycomb structure or a lattice structure made of a synthetic resin having a gradient as a core material of the panel to reduce the weight to obtain a strong lightweight heat insulating panel.

A honeycomb structure or a lattice structure made of synthetic resin means a honeycomb structure using a synthetic resin sheet as a material,
Alternatively, energy that is strong against compression can be absorbed by the lattice structure. The honeycomb structure is formed by laminating a large number of sheets having a fixed width alternately with adhesive strips to form a hove, and slicing the hove. The lattice structure is a structure in which a large number of vertical and horizontal main plate members are arranged so as to have a square cross-sectional shape.

The material of the synthetic resin sheet used for the honeycomb structure or the lattice structure is polystyrene, polyethylene,
Thermoplastic resins such as polypropylene, vinyl chloride, and polyurethane; and thermosetting resins such as phenol, urea, and epoxy; and more preferably, the same resin material as the foamed resin composition to be filled is used.

The thickness of the synthetic resin sheet used for the honeycomb structure or the lattice structure is in the range of 0.2 to 0.8 mm. The expansion ratio of the foamed resin composition is 60 to 100 times.

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, to which an inorganic material and a reinforcing short fiber are added and filled. Any foaming method can be used for foaming the resin material, for example, a method of foaming by adding a foaming agent, a foaming agent is added to a liquid resin during the polymerization reaction, the foam is stirred and foamed, and the foam does not disappear. A method of solidifying the material, a method of generating a foamed resin by generating gas in the polymerization reaction process, a process of producing a molding material by polymerizing by including a low boiling point solvent such as propane and butane in the polymerization process, and heating the molding material A foam compression molding method can be used.

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

The foamed resin composition is usually sufficient only with a resin material to which a foaming agent is added. However, when flame retardancy or high strength and rigidity are required, an inorganic material and reinforcing short fibers are added and filled. The inorganic material added and filled in the resin material to which the foaming agent has been added can improve the mechanical strength of the foamed resin and impart flame retardancy and self-extinguishing properties of the foamed resin. As the inorganic material, aluminum hydroxide, calcium carbonate, silicon oxide, calcium silicate, magnesium hydroxide, barium sulfate, gypsum, dolomite, talc, clay, mica, as a thermally decomposable inorganic material or an inorganic refractory material,
Powders such as antimony trioxide and borax can be used arbitrarily.

An organic or inorganic short fiber is added in order to strengthen the foamed resin composition. When using organic short fibers, vinylon fibers, polypropylene fibers, polyethylene fibers, which are short fibers in the range of 1 to 20 mm,
Although pulp fibers and the like can be used, vinylon fibers are more preferably used in consideration of impact strength. When inorganic short fibers are used, glass fibers of 5 mm or less, rock wool, wollastonite, sepiolite,
Carbon fiber or the like can be used.

When organic short fibers are used, the content is not more than 8 parts by weight of the total weight of the foamed resin composition constituting the lightweight heat insulating panel. Addition of more than this will impair moldability. Preferably it is 0.5 to 5 weights. When the organic short fiber and the inorganic short fiber are used together, the organic short fiber is 0.5%.
To 3 parts by weight and inorganic short fibers in a range of 0.5 to 8 parts by weight. When only inorganic short fibers are used without using organic short fibers, the amount is 1 to 10 parts by weight.

The honeycomb structure or lattice structure made of synthetic resin has one surface horizontal and the other surface has a gradient in the range of 1/100 to 1/200. The gradient may be one-way, two-way, diagonal, or both sides from the center. When a lightweight heat insulating panel is manufactured by filling the foamed resin composition, the horizontal surface of the honeycomb structure or corrugated structure is used as the back surface of the panel, and the inclined surface is used as the front surface. Since the thickness of the synthetic resin honeycomb structure or the lattice structure core material can be arbitrarily changed, it is possible to lay a lightweight heat insulating panel on the roof surface and freely form a water gradient.

The depth of the balcony of the house is 800-100
Generally, the depth is about 0 mm, and when a drain groove is provided about 150 mm, the depth feels very narrow. For this reason, the panels on both sides of the balcony are diagonally sloped, and the center panel is sloped in one direction or both sides from the center so that water flows to both corners of the balcony and drains from both corners, eliminating the need for drainage It can be.

A waterproof layer made of a waterproof coating material applied to the surface of a panel in which the foam resin composition is filled in the space of the core material and adhered on the panel is made of a waterproof layer using an asphalt-based material. A waterproof layer using a sheet made of rubber or a synthetic resin, or a waterproof layer in which a liquid material made of a synthetic resin is applied or sprayed while attaching a reinforcing cloth, a mesh, or the like may be used.

Lightweight insulation panels are used for roofing or balcony flooring. It is possible to easily form a drainage slope of a roofing material or a balcony flooring material by laying a light-weight heat insulating panel having a slanted slope. Moreover, since the panel itself has high heat insulation performance and high strength performance and rigidity, on-site construction can be easily performed.

A lightweight heat-insulating panel is attached to a waterproof construction surface of a building using a mounting fastener or an adhesive, and the panels can be joined by inserting pins if necessary. It can be stopped with a pin because it is formed in a honeycomb structure or a lattice structure.

The gradient applied to one side of the lattice structure is 1/100 in each case. The three lightweight insulation panels of ABC were used for flooring of a residential balcony. Stainless steel pins were used for joining between lightweight insulation panels. A pulp cement board was adhered to the surface of the lightweight heat-insulating panel as a non-combustible board material, and an acrylic emulsion-based coating waterproof coating material (Toyo Exterior Co., Ltd. “Reball Mighty”) was applied to the upper surface to form a waterproof layer.

The balcony of the house was 3660 mm wide and 800 mm long, and was glued to the base plywood with an adhesive in the order of ABC, and stainless steel pins were used for joining between the panels. A and B
The slope of the polystyrene lattice structure was adjusted so that the heights of the panel contacts and the B and C panel contacts were equal. In the case of this example, the drainage groove was unnecessary, and the drainage holes were installed at both corners of the balcony, so that the area of the balcony could be felt wide.

Form. A non-combustible plate is attached to the surface of the lightweight heat-insulating panel, and a waterproof coating material is applied on the upper surface thereof to form a waterproof layer.

Lightweight insulation panels are used for building roofing materials, rooftops,
The construction can be carried out easily and reliably simply by attaching to the waterproof construction surface of a building such as a balcony with a mounting bracket or an adhesive and using pins for joining between the panels, and is very suitable for repair work. Unlike the case of the above-mentioned residential balcony, a drain groove is not required, and the depth of the balcony can be made wide to be felt, so that the design is excellent. Furthermore, since the lightweight insulation panel has high rigidity and excellent performance in physical properties, it can be directly mounted on a joist.
