The present invention relates to a heat insulating material composition for a fire door and a method for manufacturing the heat insulating material for a fire door using the same.

A fire door is a door installed in an opening to prevent the expansion or combustion of a fire. These fire doors are very important facilities to minimize the propagation of flames in the event of a fire and to secure an evacuation route.

Recently, fire doors including various types of insulation materials are installed for general use in addition to the fire doors of the legalized standards, but caution is required because fire resistance or product specifications may not be sufficient.

Meanwhile, incineration ash is generated as a by-product in facilities such as thermal power generation including a combustion furnace. Examples of such incineration materials include a bottom ash in which non-combustible components and combustible components are deposited in a combustion furnace, and a fly ash filtered through a dust collecting device during scattering during combustion.

Such incinerators are limited to simple landfill and are not easy to recycle. Accordingly, there is an increasing demand for incineration ash utilization technology to increase the utilization of incineration ash and create high added value.

Conventionally, as one of methods for recycling incinerators, a method of manufacturing an insulating material by replacing ceramic particles with a fly ash is known. However, such a conventional technique uses a fly ash as a simple filler rather than a heat resistant agent, and there is a problem in that a high temperature firing process is required because glass particles, ceramic clay particles, etc. are added to supplement fire resistance.

It provides a method for manufacturing a heat insulating material for fire doors.

The combustion by-products include at least one of fly ash and bottom ash. The combustion by-products reduce the weight of the insulation for the fire door, while realizing non-heat-insulating performance and heat-insulating performance at excellent levels.

Specifically, the pearlite aggregate may be a lightweight aggregate produced by rapidly heating crushed pieces such as obsidian or perlite to a temperature of 1,000°C or higher, but is not limited thereto. In this case, the light weight of the insulation for the fire door can be further improved.

Within the above range, the effect of reducing the weight of the insulating material for fire doors by combustion by-products, non-thermal performance improvement, thermal performance improvement, impact resistance improvement effect can be more excellent.

The combustion by-products and the pearlite aggregate contain a large amount of silicon atoms, aluminum atoms, and the like in the components, so that alumino-silicate polymerization can be performed with a liquid-reactive adhesive and/or an alkali activator described later. In this case, since the combustion by-products and the pearlite aggregate are used as a mixture, they participate in a polymerization reaction in combination with each other, thereby realizing a composite synergistic effect that further improves the initial strength, impact resistance, and thermal insulation performance of the fire door insulation.

Specifically, the weight ratio of combustion by-products and pearlite aggregate in the mixture is 1:0.5 to 1:1.5, more specifically 1:0.65 to 1:1.5, for example 1:0.7, 1:0.8, 1:0.9, 1: 1, 1:1.1, 1:1.2, 1:1.3, 1:1.4, 1:1.5, and the like. Within the above range, the insulation composition for a fire door can realize a composite synergistic effect to a more excellent degree, while improving the workability of manufacturing, transportation, and installation when applied to the insulation for a fire door.

The liquid-reactive adhesive means an aqueous solution containing an adhesive component capable of reacting with the mixture and an alkali activator.

The liquid-reactive adhesive may be included in a thermal insulation composition for a fire door in an aqueous solvent state in which solid content is dissolved or dispersed, and react with a mixture of an alkali activator, a combustion by-product, and pearlite aggregate to achieve curing properties and adhesion.

Specifically, the liquid reaction adhesive may include an inorganic flame retardant solution, a surfactant solution, and an organic flame retardant solution. In this case, while further improving the fire resistance of the insulating material for fire doors, it is possible to further improve the miscibility of the entire insulating material composition for fire doors, thereby further improving the initial strength and impact resistance.

The inorganic flame retardant solution is not particularly limited, but may be, for example, silica, calcium carbonate, talc, a solution obtained by dissolving or dispersing them. The solution may be, for example, an aqueous solution. One or more of these examples may be used alone, or two or more of them may be used in combination. In this case, it is possible to further improve the initial strength and impact resistance while further improving the non-heat-insulating performance and the heat-insulating performance of the insulation for the fire door.

Specifically, the inorganic flame retardant solution in the liquid reaction adhesive may be included in 60% to 80% by weight. Within the above range, while improving the non-heat-insulating performance and the heat-insulating performance of the insulating material for fire doors, it is possible to further improve the initial strength and impact resistance.

The solution may be, for example, an aqueous solution. One or more of these examples may be used alone, or two or more of them may be used in combination. In one embodiment, the surfactant may be a cation-anionic acrylic copolymer. In this case, it is possible to further improve the initial strength and impact resistance while further improving the non-heat-insulating performance and the heat-insulating performance of the insulation for the fire door .

Specifically, the surfactant in the liquid reaction adhesive may be included in 5% to 15% by weight. Within the above range, while improving the non-heat-insulating performance and the heat-insulating performance of the insulating material for fire doors, it is possible to further improve the initial strength and impact resistance.

The resin may be, for example, a liquid resin syrup. The solution may be, for example, a diluting solvent for resin, an organic solvent, or the like. One or more of these examples may be used alone, or two or more of them may be used in combination. In this case, it is possible to further improve the initial strength and impact resistance while further improving the non-heat-insulating performance and the heat-insulating performance of the insulation for the fire door .

Specifically, the organic flame retardant in the liquid reaction adhesive may be a liquid resin. Within the above range, while improving the non-heat-insulating performance and the heat-insulating performance of the insulating material for fire doors, it is possible to further improve the initial strength and impact resistance.

Specifically, the liquid reaction adhesive, the inorganic flame retardant, surfactant, and organic flame retardant contained therein may be used in a state dissolved or dispersed in a solvent, for example, an aqueous solution having a solid content concentration of 20% to 80% by weight, It can be used as an organic solution. In this case, the effect of causing a polymerization reaction by working in combination with the mixture of the combustion by-products and the pearlite aggregate and the alkali activator may be further improved.

The liquid-type reaction adhesive in the insulating material composition for the entire fire door is included in 20 parts by weight to 35 parts by weight based on 100 parts by weight of the mixture of the above-described combustion by-products and pearlite aggregate. When the content of the liquid-reactive adhesive is less than 20 parts by weight, the polymerization reaction with the mixture and the alkali activator does not occur sufficiently, and thus it is difficult to implement excellent initial strength and impact resistance.

The alkali activator acts in combination with the mixture of combustion by-products and pearlite aggregate and a liquid-reactive adhesive to cause a polymerization reaction. Through this, the high-temperature firing process is omitted, while reducing the weight of the insulation for the fire door, improving the fire resistance, and increasing the initial strength and impact resistance.

Specifically, the alkali activator is a sodium silicate solution (Sodium silicate), a potassium silicate solution (Potassium silicate), an aluminum silicate (Aluminum silicate) solution, a lithium silicate (Lithium silicate) solution, sodium hydroxide solution and potassium hydroxide solution It may contain one or more of the solutions. In this case, the mixture of the combustion by-products and the pearlite aggregate and the liquid-reactive adhesive may be combined with the light-weight insulating material composition for fire doors to improve fire resistance and improve the initial strength and impact resistance.

Specifically, the alkali activator is used in a solution state, for example, it may be used as an aqueous solution having a solid content concentration of 30% to 70% by weight. In this case, the effect of causing a polymerization reaction by working in combination with the mixture of the combustion by-products and the pearlite aggregate and the liquid-reactive adhesive may be further improved.

The alkali activator in the insulation composition for all fire doors is included in an amount of 20 to 35 parts by weight based on 100 parts by weight of the mixture of the combustion by-products and pearlite aggregate. When the content of the alkali activator is less than 20 parts by weight, the polymerization reaction with the mixture and the alkali activator does not occur sufficiently, and thus it is difficult to realize excellent initial strength and impact resistance. Conversely, when the content of the alkali activator is more than 35 parts by weight, the insulation for the fire door is difficult to secure light weight and may inhibit reactivity by the alkali activator.

The liquid-reactive adhesive and the alkali activator of the entire insulation composition for fire doors may be included in a ratio of 1:0.6 to 1:2, 1:0.6 to 1:1.5, and 1:0.6 to 1:1. Within the above range, the effect of causing the polymerization reaction by the complex reaction of the liquid-reactive adhesive and the alkali activator may be further improved.

In another embodiment of the present invention, 100 parts by weight of a mixture of dry by-products of combustion by-products and pearlite aggregate is added, and 20 parts by weight to 35 parts by weight of a liquid reactive adhesive and 20 parts by weight to 35 parts by weight of an alkali activator are prepared.

It improves economic efficiency by improving light weight.

In the step of preparing the input raw material, a liquid reaction-type adhesive and an alkali activator are added to a mixture obtained by dry-mixing combustion by-products and pearlite aggregate, and then mixing.

Specifically, the combustion by-products and the pearlite aggregate may be additionally performed by drying each of them at room temperature for 2 to 3 days before dry mixing. In this case, the combustion by-product can reduce the amount of moisture, and further improve the reactivity of the mixture with the liquid-reactive adhesive and the alkali activator.

More specifically, the dry mixing method is not particularly limited, but may be, for example, mixing with a stirrer for 30 seconds to 60 seconds after adding pearlite aggregate to combustion by-products. In this case, the homogeneity of the insulation for the fire door can be further improved.

A liquid reactive adhesive and an alkali activator may be added to the dry mixed mixture and mixed. In this case, the mixture may react with the liquid-reactive adhesive and the alkali activator, and through this, each component participates in a polymerization reaction in combination with each other to further improve the initial strength, impact resistance, and heat shielding performance of the insulation for fire doors. It realizes a compound synergy effect.

After the input raw material is prepared as described above, the input raw material may be molded into an insulating material for a fire door. At this time, the molding method is not particularly limited, and may be heat pressing.

Specifically, the heat-pressing is performed by injecting the input raw material into a mold and pressing at a high pressure from 150°C to 200°C. In this case, it is possible to manufacture an insulating material for a fire door having excellent initial strength, impact resistance, and heat shielding performance while omitting the high temperature firing process.

Specifically, the heat pressing may be performed within a pressure range of 20 tons to 30 tons. Within the above range, the effect of improving the initial strength, impact resistance, and heat insulating performance of the insulation for the fire door may be more excellent.

More specifically, the heat pressing may be performed for 15 minutes to 60 minutes within the pressure range. Within the above range, the effect of improving the initial strength, impact resistance, and heat insulating performance of the insulation for the fire door may be more excellent.

Specifically, the insulating material for the fire door may be an insulating plate material having a thickness of 20 mm to 100 mm. In this case, the insulating material for the fire door can further improve workability, such as manufacturing, transportation, and installation, while having a size and shape suitable for use in the fire door.

In one embodiment, the step of heating and pressing is injected into a mold having the size and shape of a desired fire door, and then molded on the upper and lower plates heated to a temperature of 150°C to 200°C. Place it. The mold can be discharged as a plate-shaped insulating material having a thickness of 20 mm to 100 mm after being compressed at a pressure of 20 to 30 tons for 15 to 60 minutes.

Specifically, the heat insulating material for the fire door may have a non-thermal performance of 1 hour or more. The non-thermal performance may be measured by KS F 2268-1 (fire resistance test method for fire doors). In this case, the insulation for the fire door can be applied not only to a general fire door, but also to a fire door that requires a legalized standard.

Specifically, the heat insulating material for the fire door may have a heat shielding performance of 0.5 hours or more. The heat shield performance may be measured by KS F 2268-1 (fire resistance test method for fire doors). In this case, the insulation for the fire door can be applied not only to a general fire door, but also to a fire door that requires a legalized standard.
