[Industrial applications]

 The present invention relates to a lightweight base insulation panel for use as a wall material, roofing material, rooftop, balcony, flooring, tatami, etc. for buildings such as general buildings and homes, which has a lightweight insulation and excellent rigidity. is there.

[0002]

[Prior art]

 Conventionally, a lightweight insulating panel for a base made of a synthetic resin is a sheet material obtained by extrusion-foaming a synthetic resin foam-molded product and then cutting the synthetic resin foam-molded product into a predetermined shape dimension or a bead molding.

However, in any of the methods, the lightweight insulation panel for base made of a synthetic resin foam-molded product is a synthetic resin foam-molded product, so that it is weak in compressive strength and is easily chipped at the ends. Therefore, in order to maintain the compressive strength and the strength of the synthetic resin foam-molded product without chipping, the expansion ratio of the synthetic resin foam-molded product had to be reduced considerably, resulting in a high material cost.

However, in actuality, the expansion ratio cannot be lowered so much in view of the material cost, and the expansion ratio is generally about 30 to 50 times, and it is impossible to completely prevent the chipping of the end portion.

[Action]

 Hereinafter, the present invention will be described. A synthetic resin honeycomb structure serving as a core material of a panel, a corrugated structure, or a lattice structure is filled with a foamed resin composition to reduce the weight to form a strong and lightweight heat insulating panel.

The synthetic resin honeycomb structure, corrugated structure, or lattice structure is a honeycomb structure, corrugated structure, or lattice structure that uses a synthetic resin sheet as a material and can absorb strong energy against compression. . The honeycomb structure and the corrugated structure are formed by stacking a large number of sheets having a constant 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 plates are arranged so that the cross-sectional shape is a square.

The material of the synthetic resin sheet used for the honeycomb structure, corrugated structure, or lattice structure is a thermoplastic resin such as polystyrene, polyethylene, polypropylene, vinyl chloride, or polyurethane, or a thermosetting resin such as phenol, urea, or epoxy. Although it is a resin or the like, it is more preferable to use the same resin material as the foaming resin composition to be filled.

The thickness of the synthetic resin sheet used for the honeycomb structure, corrugated structure, or 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 and an inorganic material and reinforcing short fibers are added and filled. Any foaming method can be used to foam the resin material.For example, a foaming method can be used by adding a foaming agent, or a foaming agent can be added to the liquid resin during the polymerization reaction and agitated to foam the foam so that the foam disappears. In the polymerization process, a gas is generated during the polymerization reaction to form a foamed resin.In the polymerization process, a low boiling solvent such as propane or butane is included to polymerize to form a molding material, and this molding material is heated. Then, 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 or polyurethane, or a thermosetting resin such as phenol, urea, epoxy or hard polyurethane.

In general, a resin material to which a foaming agent is added is sufficient for the foamed resin composition. However, particularly when flame retardancy or high strength and rigidity are required, an inorganic material and a reinforcing short fiber are added and filled. The inorganic material added and filled in the resin material added with the foaming agent can improve the mechanical strength of the foamed resin and impart flame retardancy and self-extinguishing property of the foamed resin. As the inorganic material, heat-decomposable inorganic material or inorganic refractory material 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.

In order to make the foamed resin composition tough, organic or inorganic short fibers are added. When using organic short fibers, 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 fibers will be used. It is more preferably used. When the organic 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 thereof is 8 parts by weight or less based on the total weight of the foamed resin composition forming the lightweight heat insulation panel. Addition of more than this will impair moldability. It is preferably 0.5 to 5 parts by weight. When using organic short fibers and inorganic short fibers in combination, the organic short fibers should be in the range of 0.5 to 3 parts by weight and the inorganic short fibers in the range of 0.5 to 8 parts by weight. To do. In the case of using only inorganic short fibers without using organic short fibers, the amount is 1 to 10 parts by weight.

When the lightweight insulation panel according to the present invention is used as a base of a balcony of a house, the depth of the balcony of the house is generally about 800 to 1000 mm, and the depth of the drainage groove is about 150 mm. I feel narrow. For this reason, the panels on both sides of the balcony are diagonally inclined, and the central panel is unidirectional or inclined from the center to both sides so that water flows to both corners of the balcony and drains from both corners to form a drainage groove. It can be unnecessary.

A waterproof layer made of an asphalt-based material is a waterproof layer formed by sticking a non-combustible plate material on the surface of a lightweight heat-insulating panel filled with a foamed resin composition in the space of a core material and applying it on the surface. It may be a waterproof layer using a sheet made of synthetic rubber or synthetic resin, or a waterproof layer formed by applying or spraying a synthetic resin liquid material while attaching a reinforcing cloth and a mesh.

Lightweight insulation panels are used for roofing or balcony flooring. It is possible to easily form the draining slope of the roofing material or the balcony flooring material by laying the light-weight insulation panel with the slope formed obliquely. In addition, since the panel itself has high heat insulation and high strength and rigidity, on-site construction can be performed easily.

A lightweight heat insulating panel can be attached to a waterproof surface of a building by using a mounting metal fitting or an adhesive, and the joint between the panels can be stopped by inserting a pin if necessary. It can be stopped with a pin because it is formed with a honeycomb structure, a corrugated structure, or a lattice structure.

【Example】

 An embodiment in which the lightweight insulation panel of the present invention is used as a base of a balcony of a house will be described below.

Example A polystyrene lattice structure having a cell size of 50 mm in length and width, a core material having a thickness of 30 mm, and a thickness of 0.4 mm was used as a core material of a lightweight heat insulation panel. The foamed resin composition is a molding material obtained by polymerizing polystyrene by incorporating a low boiling point solvent such as propane and butane, and has a foaming ratio of 80 times.

The foamed resin composition was filled in the space of the polystyrene lattice-structured core material and heated at 100 ° C. to be integrally molded. The dimensions of the lightweight heat insulation panel were 800 length × width 1220 mmA BC 3 sheets, A was a diagonal gradient from the right to the left, B was a bidirectional gradient from the center, and C was a diagonal gradient from the left to the right. The gradient applied to one side of the lattice structure is 1/100. The three lightweight insulation panels of this ABC were used as the floor material of the house balcony. Stainless steel pins were used to join the lightweight insulation panels. A pulp cement board was attached as a non-combustible board material to the surface of the lightweight heat insulation panel, and an acrylic emulsion-based waterproof coating material for coating (Toyo Exterior Co., Ltd., "Revol Mighty") was applied on the upper surface to form a waterproof layer.

The balcony of the house had a width of 3660 mm and a length of 800 mm, and was adhered to the base plywood with an adhesive in the order of ABC, and stainless steel pins were used for joining the panels. The gradient of the polystyrene lattice structure was adjusted so that the heights of the contacts of the A and B panels and the contacts of the B and C panels were equal. In the case of this example, the drainage groove was not necessary, and the drainage holes were installed at both corners of the balcony, so that the area of the balcony could be widely felt.

[0024]

[Effect of the invention]

 The lightweight heat insulation panel of the present invention is formed by using a synthetic resin honeycomb structure, corrugated structure, or lattice structure core material as a reinforcing core, and filling the foamed resin composition in this space. When this lightweight heat insulating panel is used as a base material for construction, a non-combustible plate material or the like can be attached to the surface and a finish coating material can be applied to the upper surface of the panel.

[0025] Lightweight insulation panels can be easily and reliably constructed by simply attaching them to the waterproof construction surface of the building roofing material, rooftop, balcony, etc. with a mounting bracket or adhesive and using pins to join the panels. It is also suitable for repair work. As in the case of the above-mentioned residential balcony, the depth of the balcony can be widely felt without the need for draining grooves, which is excellent in design. Furthermore, since the lightweight insulation panel has high rigidity and excellent performance in terms of physical properties, it can be mounted directly on the joists. Even when used as a core material for tatami mats, sufficient rigidity can be obtained with half the weight of the conventional one.
