[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 for a roof material, a rooftop, a balcony, a floor material of a building such as a general building and a house.

[0002]

[Prior art]

 The waterproof structure of the conventional construction is a sheet waterproof method that covers metal plates and sheets, an asphalt waterproof method that creates a waterproof layer using an asphalt material, a mortar method that applies mortar, and a synthetic resin waterproof material. There is a construction method of applying a to form 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 waterproof structure by the conventional waterproofing method completely covers the surface to be waterproofed, peeling or floating may occur due to the influence of air, moisture, etc. generated from the surface to be waterproofed. . Therefore, there was a problem that a degassing tower had to 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. There was also the problem that it was not possible to work in the rain due to the weather conditions due to the large amount of outdoor construction, which made it difficult to construct a complete waterproof structure on site.

[0006]

[Problems to be solved by the device]

 The present invention has been made to solve such a problem, and the front and back surfaces and the end surface of the lightweight insulation panel based on the glass fiber-mixed inorganic phenolic resin foam plate with the gradient produced at the factory are used. It is a lightweight and heat-insulating waterproof panel with a slope that has a waterproof layer formed by applying a waterproof coating to the six sides of the panel.It is laid on balconies, rooftops, floors, etc. It can be done easily without the need for on-site work such as slopes, and there is no need to worry about the quality of the finished work due to differences in the skill levels of the workers, and the work can be carried out immediately even after the rain, eliminating the need for waiting time. Another object is to provide a lightweight heat-insulating waterproof panel that can completely prevent water leakage due to cracks in the coating film.

[0007]

[Means for Solving the Problems]

 As a result of earnest research aimed at solving these problems, as a result of applying a waterproof coating material to the front and back surfaces and the six panels of the end surface of the lightweight heat insulation panel based on a gradient glass fiber-mixed inorganic phenolic resin foam board as a base material. It was solved by a lightweight insulation and waterproof panel characterized by forming a waterproof layer.

[0008]

[Action]

 The present invention will be described below. Lightweight heat insulation that uses a gradient glass fiber mixed phenolic resin foam plate as the core material of the panel as the base material. Form a waterproof panel.

Inorganic phenolic resin foam board mixed with glass fiber is a resol-type phenolic resin or a resol-type phenolic resin to which one or more guanidine salts and optionally urea are added, and methylene chloride, carbonate, etc. Foaming agent and phenol resin In order to improve the fire resistance and shape retention of foamed board material, one or more of aluminum hydroxide, ammonium polyphosphate, graphite, calcium silicate, calcium carbonate, etc., curing agent, inorganic bone It is a non-combustible material that is made of a material, glass fibers having a length of 5 mm or less, and is foamed and cured to form a light weight.

The glass fiber-mixed inorganic phenolic resin foam plate material can be extruded, casted, etc., and has a specific gravity of around 0.4, which is extremely lightweight and is certified as a nonflammable material despite being plastic. Is.

The waterproof layer made of a waterproof coating applied to the front and back surfaces and the six end surfaces of the base material is a waterproof layer made of an asphalt-based material, a waterproof layer made of a synthetic rubber or synthetic resin sheet, a synthetic resin. Although a waterproof layer formed by applying a liquid material made of reinforced cloth and a mesh or the like may be applied, a waterproof film layer is more preferable in the present invention.

[0012] The waterproof coating film can be certified as a non-combustible material equivalent to the base material of the Ministry of Construction, and is mainly composed of synthetic resin emulsion, such as acrylic resin emulsion, vinyl acetate resin emulsion, vinyl chloride. Resin emulsions, vinylidene chloride resin emulsions, styrene-butadiene resin emulsions, epoxy resin emulsions and copolymers with acrylic acid esters, styrene, ethylene, vinyl esters, vinyl acetate, synthetic rubber, etc. .

Examples of these copolymers include acrylic / vinyl acetate copolymers, vinylidene chloride / butyl acrylate copolymers, ethylene / vinyl acetate copolymers and the like. The amount of the synthetic resin emulsion composition used is in the range of 8 to 30% by weight. If it is 8% by weight or less, the physical properties of the coating material are not improved, and if it is 30% by weight or more, the stability of the coating material is lowered and it becomes difficult to obtain a nonflammable coating material equivalent to the base material.

In addition to the above, the coating material according to the present invention improves various properties of the coating material according to need. Therefore, various surfactants as dispersing agents, emulsifiers for stabilizing emulsions, and prevention of whipping of emulsion Agents, thickeners, anti-sagging agents, anti-settling agents, anti-freezing agents and the like may be added. Further, for the purpose of improving the performance of the coating film, a plasticizer that imparts flexibility to the coating film, a stabilizer that prevents deterioration due to heat or light, and an antifungal agent that prevents generation of mold may be added.

A heat-insulating lightweight panel using a glass fiber-mixed inorganic phenolic resin plate as a base material has one surface horizontal and the other surface having a gradient in the range of 1/100 to 1/200. The slope may be unidirectional, bidirectional, diagonal, or centered on both sides. The lightweight insulation and waterproof panel has a horizontal surface as the back surface of the panel and a sloping surface as the front surface. Since the thickness of the lightweight insulation and waterproof panel can be changed arbitrarily, it is possible to lay the panel on the rooftop or balcony to freely form a water gradient.

The depth of a balcony of a house is generally about 800 to 1000 mm, and if a drainage groove is provided on this for 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 unidirectional or sloped from the center to both sides so that water flows to both corners of the balcony and drains from both corners. The groove can be eliminated.

The lightweight heat-insulating and waterproof panel having a waterproof layer formed by applying a waterproof coating material to the six surfaces of the lightweight heat-insulating panel is used by laying and sticking it on a roof material, a rooftop, a balcony, a floor material or the like. By laying panels with a slanted slope on the panel surface, it is possible to easily form draining slopes for roofing materials, balconies, or floor materials. Moreover, since the panels have high heat insulation and high waterproofness, it is sufficient to lay and stick the panels and fill the joints between the panels with the sealing material for on-site construction.

A lightweight adiabatic / waterproof panel having a waterproof layer formed by coating the front and back surfaces and the six end surfaces of the panel with a waterproof coating material is used for waterproofing work on balconies and rooftops. A lightweight, heat-insulating waterproof panel is attached to the surface to be waterproofed of the building using a metal fitting or adhesive, and the joints between the panels are sealed with a sealing material, and the top surface of the sealing material is a noncombustible waterproof material if necessary Apply with.
