[0029] Composite insulation for construction

[0030] FIG. 1 is a perspective view of a composite insulation material for construction according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of FIG. 1. Hereinafter, a composite insulation material for construction according to an embodiment of the present invention will be described with reference to FIG. 1 and FIG. 2.

[0031] A composite insulation material (100) for construction according to one embodiment of the present invention is formed in a structure in which a base (110), a hollow plate (130), and a semi-fireproof sheet (150) are sequentially laminated.

[0032] The base (110) is a component made of foamed synthetic resin, and can be manufactured by mixing a foaming agent and polystyrene resin, and then compressing, cooling, and cutting in a high temperature / high pressure environment inside a mold.

[0033] The hollow plate (130) is manufactured from a thermoplastic synthetic resin and placed on top of the base (110). At this time, the synthetic resin may be a pure synthetic resin that does not contain silicate minerals. It can be manufactured by melt-mixing pure thermoplastic synthetic resins together and then using an injection molding process. This hollow plate (130) can be provided with a thickness of 2.0 mm or more and 3.0 mm or less.

[0034] These bases (110) and hollow plates (130) can be provided with a uniform thickness and shape.

[0036] Meanwhile, a composite insulation material (100) according to one embodiment of the present invention includes a semi-fireproof sheet (150). The semi-fireproof sheet (150) is placed on top of the aforementioned hollow plate (130). As previously described, conventional composite insulation materials consist of a base made of synthetic resin and a hollow plate, which had the problem of high flammability when exposed to fire. However, to solve this problem, the present invention adds a semi-fireproof sheet (150) to the base (110) and the hollow plate (130). The semi-fireproof sheet (150) acts as a barrier layer that blocks flames and cuts off oxygen supply, and is composed of a material having performance of a semi-fireproof grade or higher.

[0037] Specifically, the semi-fireproof sheet (150) is composed of a glass fiber layer (151) and a coating layer (152).

[0038] First, the glass fiber layer (151) is made of glass fiber. Glass fiber is known as an inorganic mineral fiber insulation material formed by melting glass at a high temperature, using high-speed rotational force to make the glass into fibers, and then using a binder to form them into a certain size; it has excellent thermal insulation and heat retention properties. In particular, because it is inorganic, it does not burn easily and has good fire resistance. This glass fiber layer (151) is a non-combustible material that provides fire resistance while improving the durability and strength of the composite insulation material (100). In the present invention, the type of glass fiber is not limited. The thickness of this glass fiber layer (151) may be 0.3 mm or more.

[0039] Meanwhile, the coating layer (152) is placed on the glass fiber layer (151) and can be prepared by coating a material containing cement, inorganic substances, and additives. At this time, the inorganic component may include stone powder.

[0040] For reference, FIG. 5 is a cross-sectional view of a composite insulation material for construction according to another embodiment of the present invention. As shown in FIG. 5, a semi-fireproof sheet (150) may have a thin film (160) attached to one side thereof, that is, the attachment surface (e.g., the bottom surface) with respect to the hollow plate (130), and the thin film (160) may be an aluminum thin film. The aluminum thin film is a fireproof heat-reflective insulation material and has excellent heat-reflective performance. That is, it reflects radiant heat of thermal energy to prevent the internal temperature from rising due to this radiant heat, and in winter, it prevents internal heat energy from being conducted and lost to the outside. Due to this heat-reflective performance, the insulation performance of the composite insulation material of the present invention is efficiently increased. Additionally, the aluminum thin film has the advantage of excellent water resistance.

[0041] In the structure of a composite insulation material for construction according to another embodiment illustrated in FIG. 5, the semi-fireproof sheet (150) is configured such that a cement, inorganic, and additive coating layer (152) is disposed on the upper surface of a glass fiber layer (151), and an aluminum film (160) is disposed on the lower surface of the semi-fireproof sheet (150), that is, on the lower surface of the glass fiber layer (151). By placing the coating layer (152) on the uppermost layer of the composite insulation material, finishing work such as painting or wallpapering is facilitated, and by placing the film (160) on the lower surface facing the hollow plate (130), the hollow plate (130) of the synthetic resin is protected. Since the surface of the aluminum film has poor adhesion performance, the film (160) and the hollow plate (130) are bonded by a second adhesive layer (172) (hot melt adhesive) as described later.

[0042] Meanwhile, the semi-fireproof sheet (150) according to the present invention may have a thickness of 0.4 mm or more and 1.0 mm or less. According to this configuration, there are advantages such as excellent lightness, cutability, and workability.

[0043] division Test items unit Test results Judgment criteria 1 time 2nd time 3 times Interior finishing materials Heat release rate test Heat release amount MJ / m3 0.8 0.8 0.7 8 or less Time when the heat release rate continuously exceeds 200 kW / m³ s 0 0 0 Less than 10 Presence or absence of fire hazard factors in the test specimen - No issues No issues No issues There won't be Gas toxicity test Average behavioral cessation time of test white rats min:s 14:22 14:54 - 9:00 or later

[0045] Table 1 shows the test results conducted by the Korea Chemical Fusion Testing & Research Institute. As can be seen from Table 1 above, the results of the heat release rate test and the gas toxicity test confirm that the semi-noncombustible sheet (150) film (0.45 mm) of the present invention satisfies the test standards for semi-noncombustible materials as specified in Ministry of Land, Infrastructure and Transport Notice No. 2023-24.

[0046] In addition, by setting the thickness of the semi-fireproof sheet (150) to be thin, such as 0.4 mm or more and 1.0 mm or less, the lightweight nature of the composite insulation material (100) is maintained, making it easy to cut with a cutter knife.

[0048] Meanwhile, the semi-fireproof sheet (150) composed of a glass fiber layer (151) and a coating layer (152) according to the present invention is provided as an independent member separate from the base (110) and the hollow plate (130). While conventional general composite insulation materials are manufactured by applying a compounding paste to a base and then undergoing a drying and curing process, the present invention does not apply this method and can manufacture a finished composite insulation material by bonding the semi-fireproof sheet (150) to the bonding member of the base (110) and the hollow plate (130) using the aforementioned solid adhesive.

[0050] Meanwhile, the present invention bonds a base (110) and a hollow plate (130), and a hollow plate (130) and a semi-fireproof sheet (150) using a solid adhesive. Specifically, a first adhesive layer (171) is a solid adhesive and is placed between the base (110) and the hollow plate (130) to bond them, and a second adhesive layer (172) is a solid adhesive and is placed between the hollow plate (130) and the semi-fireproof sheet (150) to bond them.

[0051] In this case, the solid adhesive is a reactive hot melt adhesive. Reactive hot melt adhesives (HMA) are a type of adhesive that forms strong and long-lasting bonds by chemically reacting with moisture in the air to crosslink. Unlike general hot melt adhesives that rely solely on physical adhesion, they undergo a curing step to generate adhesive strength with improved strength and lifespan. This solid adhesive is a thermoplastic solid at room temperature, is applied in a molten state, and develops initial adhesive strength as it cures upon cooling. This solid adhesive can be prepared with a uniform thickness of 0.1 mm or more and 0.2 mm or less.

[0052] At this time, the reactive hot melt adhesive according to one embodiment of the present invention may contain isocyanate. Meanwhile, the reactive hot melt adhesive according to another embodiment of the present invention may be formed by alternately copolymerizing a polystyrene block, polybutadiene, and a polyisoprene block.

[0053] Meanwhile, the present invention can improve the adhesive performance between the base (110) and the hollow plate (130), or between the hollow plate (130) and the semi-fireproof sheet (150), by applying a solid adhesive. That is, conventionally, a method was applied in which an oil-based or water-based adhesive was used to bond the base and the hollow plate, followed by evaporative drying of the adhesive. However, since both the base and the hollow plate are non-breathable materials, there was a disadvantage in that the adhesive did not evaporate and dry. Consequently, there was a problem in that the adhesive strength between the base and the hollow plate decreased and the composite insulation material was deformed. However, since the present invention applies a solid adhesive instead of an oil-based or water-based adhesive, evaporative drying is not required, and thus there is an advantage in that the non-breathable base (110) and the hollow plate (130) can be bonded easily and strongly.

[0054] More specifically, a solid adhesive is first applied in a molten state onto a base (110), a hollow plate (130) is attached onto the solid adhesive, and then cured by natural cooling to bond the base (110) and the hollow plate (130) together. For reference, the solid adhesive melts at a temperature of 160°C or higher, the base (110) is a foamed synthetic resin and undergoes deformation due to heat at 70°C or higher, and the hollow plate (130) is a synthetic resin and is adversely affected near 100°C. Accordingly, a method can be applied by applying the solid adhesive to the upper surface of the base (110) when it has cooled to 70°C, then placing the hollow plate (130), and then cooling and curing.

[0055] Meanwhile, the present invention can increase the surface smoothness of the semi-fireproof sheet (150) by applying a solid adhesive. More specifically, the hollow plate (130) can be manufactured by injection molding as described above, in which case irregularities exist on the surface of the hollow plate (130) during the injection cooling process. However, if a solid adhesive in a molten state is applied to the upper part of the hollow plate (130) and the semi-fireproof sheet (150) is placed on the solid adhesive and press-processed, the irregularities on the surface of the hollow plate (130) are filled by the solid adhesive, and the grooves between the irregularities are filled. Furthermore, since the solid adhesive hardens while undergoing cooling during press processing, it has no flowability, allowing the surface of the semi-fireproof sheet (150) on the upper part to maintain a smooth state.

[0056] As previously mentioned, the composite insulation material according to the prior art had a structure in which a synthetic resin base and a synthetic resin hollow plate were bonded together. However, the hollow plate had a problem of poor paintability and adhesion due to the unevenness of its surface, and therefore, finishing work such as painting, wallpapering, or attachment could not be performed on the hollow plate. Accordingly, in the past, when the hollow plate was injection molded, a fiber sheet such as non-woven fabric was embedded in its surface; however, when a finishing material such as tile was attached to the fiber sheet, the adhesion strength decreased, resulting in poor bonding performance and construction defects. However, as in the present invention, a semi-fireproof sheet (150) film was attached to the hollow plate (130) using a solid adhesive. The semi-fireproof sheet (150) has excellent paintability and superior adhesion strength, which can solve the problem of finishing workability of the hollow plate (130) according to the prior art. In addition, as described above, by bonding the semi-fireproof sheet (150) to the hollow plate (130) using a solid adhesive, the surface of the semi-fireproof sheet (150) can be maintained in a smooth state, thereby having the advantage of excellent paintability and adhesion.

[0058] According to this configuration, a semi-noncombustible sheet (150) is bonded to the base (110) and the hollow plate (130), so that when a fire occurs in the building, the semi-noncombustible sheet (150) can block the conduction of fire and heat to the base (110) and the hollow plate (130). Accordingly, by blocking the supply of oxygen to the base (110) and the hollow plate (130) made of synthetic resin material, it is possible to prevent these components from igniting or to prevent or delay the melting of these components by high heat.

[0059] In addition, by providing a semi-fireproof sheet (150) using a solid adhesive on the upper part of the hollow layer, the surface of the semi-fireproof sheet (150) is configured to be smooth, thereby increasing the finishing workability of the composite insulation material (100), and since the semi-fireproof sheet (150) contains glass fibers, the durability of the composite insulation material (100) can be improved.

[0061] Method for manufacturing composite insulation for construction

[0062] FIG. 3 is a conceptual diagram showing a method for manufacturing a composite insulation material for construction according to one embodiment of the present invention, and FIG. 4 is a conceptual diagram showing a method for manufacturing a composite insulation material for construction according to another embodiment of the present invention. Hereinafter, with reference to FIG. 3 and FIG. 4, a method for manufacturing a composite insulation material (100) for construction according to one embodiment of the present invention will be described.

[0064] A method for manufacturing a composite insulation material (100) for construction according to the present invention comprises a first step of combining a hollow plate (130) and a semi-fireproof sheet (150), a second step of placing a first adhesive layer (171) on the upper part of a base (110), and a third step of attaching a combination member of the hollow plate (130) and the semi-fireproof sheet (150) to the base (110) via the first adhesive layer (171). At this time, the semi-fireproof sheet (150) comprises glass fibers, cement, and inorganic materials.

[0065] The composition of the base (110), hollow plate (130), and semi-fireproof sheet (150) has been explained previously, and a repeated explanation is omitted, and the aforementioned details are adopted.

[0067] In the method for manufacturing a composite insulation material (100) of the present invention, the first step may employ two methods, and each method is described.

[0069] First, according to one embodiment of the present invention, the first step is performed by embedding a semi-fireproof sheet (150) in a hollow plate (130) and then injecting it. As described above, the hollow plate (130) can be manufactured by melting and mixing pure thermoplastic synthetic resins together and then using an injection molding method. The semi-fireproof sheet (150) is embedded in the hollow plate (130) prior to the injection molding process, and then injected together to obtain a hollow plate (130) with the semi-fireproof sheet (150) embedded therein. In this embodiment, a bonding method using a solid adhesive is not applied when the semi-fireproof sheet (150) is attached to the hollow plate (130). More specifically, the method of producing the hollow plate (130) with the semi-fireproof sheet (150) embedded therein is as follows.

[0070] First, synthetic resin raw materials are fed into a hopper. The synthetic resin may be fed in the form of pellets, and at this time, only pure synthetic resin of 99% or more may be used. To improve the physical properties of the hollow plate (130), such as hardness, strength, wear resistance, and ease of processing, wood powder or stone powder in the form of powder or chips may be added. At this time, air is injected to uniformly mix the raw materials, thereby preventing clumping of the raw materials. However, if pure synthetic resin of 99% or more is used as a raw material, air injection is not required.

[0071] Next, the synthetic resin raw material is heated and melted, and then the molten, high-temperature synthetic resin is injected into a mold and extruded. As the synthetic resin passes through the extruder and then through a die mounted at the end of the extruder, a continuous product with a uniform cross-section can be produced.

[0072] Next, a semi-fireproof sheet (150) is embedded in the extruded molten synthetic resin. That is, the semi-fireproof sheet (150) is attached to the extruded molten synthetic resin and bonded and embedded by a heat-induced fusion method. In this process, a sheet roll is additionally installed to unwind and pull the roll around which the semi-fireproof sheet (150) is wound, thereby controlling the tensile strength of the semi-fireproof sheet (150). Since a general fiber sheet is a synthetic resin sheet (i.e., a non-woven fabric), it stretches at a similar elongation rate at a melting temperature similar to that of a synthetic resin hollow plate, making it easy to fuse with the synthetic resin hollow plate by heat. However, the semi-fireproof sheet (150) of the present invention is an inorganic glass fiber sheet, and since the melting temperature of the glass fiber sheet (about 650°C or higher) is significantly different from the melting temperature of the synthetic resin sheet (about 200°C or lower) and the difference in elongation is also significant, it is not easy to bond and embed the semi-fireproof sheet (150) into the hollow plate (130). In this regard, the semi-fireproof sheet (150) is bonded and embedd into the hollow plate (130) while controlling the tensile strength of the semi-fireproof sheet (150).

[0073] Next, the hollow plate (130) in which the semi-fireproof sheet (150) is embedded is cooled and solidified, and then cut to a desired length.

[0074] Meanwhile, according to another embodiment of the present invention, the first step is performed by attaching a hollow plate (130) and a semi-fireproof sheet (150) with a solid adhesive. More specifically, the steps of placing a second adhesive layer (172) on the upper surface of a synthetic resin hollow plate (130), placing a semi-fireproof sheet (150) on the upper surface of the second adhesive layer (172), and pressing and heating the hollow plate (130) and the semi-fireproof sheet (150) are performed sequentially. This embodiment applies a bonding method using a solid adhesive when attaching the semi-fireproof sheet (150) to the hollow plate (130).

[0075] At this time, the step of placing a second adhesive layer (172) on the upper surface of the hollow plate (130) includes the step of melting a solid adhesive, the step of cooling the melted solid adhesive to a preset temperature, and the step of applying the cooled solid adhesive to the upper surface of the hollow plate (130).

[0076] As described above, the solid adhesive is a thermoplastic solid at room temperature, is applied in a molten state, and is a material that exhibits adhesive strength as it hardens upon cooling. For reference, the solid adhesive melts at a temperature of 160°C or higher, and the hollow plate (130) is affected by heat at around 100°C. Therefore, after the step of heating and melting the solid adhesive to a temperature of 160°C or higher, when the solid adhesive is cooled to a preset temperature, i.e., 100°C or lower, the cooled solid adhesive is applied to the upper surface of the hollow plate (130). Then, a semi-fireproof sheet (150) is placed on the solid adhesive and then cooled and cured.

[0078] After combining the hollow plate (130) and the semi-fireproof sheet (150) through one of the two methods described above, a second step of placing a first adhesive layer (171) on the upper part of the base (110) and a third step of attaching a combination member of the hollow plate (130) and the semi-fireproof sheet (150) to the base (110) via the first adhesive layer (171) are performed.

[0079] For reference, the solid adhesive melts at a temperature of 160°C or higher, the hollow plate (130) is affected by heat near 100°C, and the base (110) undergoes deformation due to heat at 70°C or higher. Therefore, a method can be applied in which the solid adhesive is applied to the upper surface of the base (110) when it has cooled to a preset temperature, i.e., 70°C, and then a bonding member of the hollow plate (130) and the semi-fireproof sheet (150) is placed and then cooled and cured.

[0081] The above description is merely one embodiment for implementing the composite insulation material for construction and the method for manufacturing the same according to the present invention. The present invention is not limited to the above-described embodiment, and the technical spirit of the present invention extends to the scope in which various modifications can be made by anyone with ordinary knowledge in the field to which the invention belongs, without departing from the gist of the invention as claimed in the following patent claims.
