Description

PANEL COMBINED NONCOMBUSTIBLE AGENT INJECTED STYROFOAM AND NONCOMBUSTIBLE MATERIALS}

The present invention relates to a building heat insulating material, and more particularly, to a building panel in which a flame retardant is injected to combine a styrofoam reinforced with a non-flammable inorganic insulating material.

Currently, non-combustible and heat-insulating materials used in Korea are currently using organic chemical products such as gypsum board, styrofoam, glass wool, or ceramic fibers.

These organic chemical products were easily burned in the event of fire, toxic gas was generated, and it was necessary to take asphyxiation, loss of life, and property loss. The demands for the development of building materials such as non-combustible materials and insulation materials have been recovered endlessly. The problem is reaching its limit.

In addition, the insulation materials used in construction, such as Styrofoam, glass fiber, urethane, and rock wool, have been widely used throughout the industry. However, as the main culprit of global warming and environmental destruction, products made from these materials will be turned away from consumers.

In particular, Styrofoam waste takes 500 years to rot in the ground and generates many toxic gases during combustion.

Urethane foam is mixed with isocyanate and polyol and sprayed in the field to fill the blank or molded into a sheet, but it contains freon, pentane, and carbon dioxide, which proved to be very inadequate for environmental pollution. In recent years, it is not used.

Glass fiber also has good thermal insulation and processability, but it causes industrial illnesses due to fine dust when handling, which avoids manpower handling and damages the environment during waste disposal.

In order to overcome these problems, the present applicant has applied for and registered the registration number 10-0807245 (non-flammable inorganic insulation), but this non-flammable inorganic insulation is very excellent insulation effect, it is necessary to supplement the mechanical strength It has been confirmed.

In addition, styrofoam, widely used as a building insulation material, is a combustible material, which causes rapid ignition when a fire occurs and generates a large amount of toxic gas, which is a direct cause of a large accident.

Recently, in order to prevent an accident in the event of a fire, non-combustible or flame retardant interior materials are constantly being developed, and Styrofoam is also developed or distributed in the market.

However, in the case of such a non-combustible styrofoam, the effect is so small that the combustion rate is slightly lower than that of the conventional combustible styrofoam rather than non-combustible.

In addition, the manufacturing process is complicated, causing a rise in the manufacturing cost, so that combustible styrofoam can only be used as a building material.

As a result, such a conventional non-combustible styrofoam is insignificant in delaying the combustion rate of the combustible material, cannot completely suppress the generation of toxic gases, and the manufacturing process is complicated, so that the manufacturing cost is increased and practically insufficient.

An object of the present invention for solving the above-mentioned problems is to provide a lightweight non-flammable insulation that is not burned, protects life and property in the event of a fire, exerts heat insulation performance, is light and excellent in workability, and in particular, has excellent mechanical strength in tensile strength. Is in.

In addition, by producing a non-combustible styrofoam to reduce gas emissions as much as possible to give a time to evacuate people in the fire to prevent the loss of life and economic as much as possible.

In addition, by providing a building panel in which a thermal insulation styrofoam and a non-combustible heat insulating material is combined to provide an eco-friendly building panel having excellent heat insulation effect and excellent non-combustibility.

In order to achieve the above object, a panel in which a flame retardant-injected styrofoam and a non-combustible heat insulator are combined includes an inorganic foam obtained by rapidly heating glassy rocks with gas or electricity to vaporize crystal water; A flame-retardant inorganic heat insulating material mixed with a water glass (Na ₂ O.SiO ₂ ), a flame retardant, antimony, and polyvinyl acetate (PVA); Styrofoam in which water (H ₂ O), flame retardant sodium silicate (Na ₂ SiO ₃ ), viscosity enhancer starch, curing agent and sodium chloride were injected and dried, and then cured flame retardant was injected with an inorganic adhesive. It is characterized by being.

Here, the mixing ratio of the inorganic foam and the auxiliary material is 2: 1, and the auxiliary material is stirred at a ratio of 65 to 70% by weight of water glass, 27.5 to 32.5% by weight of flame retardant, 2.48 to 3.0% by weight of antimony and 0.01 to 0.02% by weight of PVA. It is desirable to implement as possible.

Here, the auxiliary material is preferably stirred at a ratio of water glass 67% by weight, flame retardant 30% by weight, antimony 2.985% by weight and PVA 0.015% by weight.

Here, the composition of the styrofoam is preferably 50% by weight of water (H ₂ O), 30% by weight of sodium silicate (Na ₂ SiO ₃ ), 10% by weight starch, 8% by weight of the curing agent and 2% by weight of sodium chloride.

Here, the panel combined with the flame retardant-injected Styrofoam and flame retardant insulation may be used as a ceiling material, sound insulation, dry bit insulation, sandwich panel filler or interior and exterior materials of buildings.

According to the above-described configuration of the present invention, flame retardant which is not burned, protects life and property in the event of fire, exerts thermal insulation performance, is light and has excellent workability, has excellent mechanical properties (tensile strength), and has excellent thermal insulation effect and noise blocking effect. It is possible to provide a panel in which the injected styrofoam and the non-combustible insulation are combined.

[ Flame retardant  Infused Styrofoam  Composition and Manufacturing Process]

Styrofoam infused with a flame retardant according to the present invention is 50% by weight of water (H ₂ O), 30% by weight of sodium silicate (Na ₂ SiO ₃ ) as a flame retardant, 10% by weight of starch as a viscosity modifier, 8% by weight of a curing agent and 2% of sodium chloride It is prepared by injecting a stirred flame retardant liquid phase and drying / curing.

Here, sodium silicate (Na ₂ SiO ₃ ) is used as a nonflammable agent, 30% by weight based on the total weight, starch is used by 10% by weight relative to the total weight, which is used as an auxiliary to reinforce the viscosity. In addition, sodium chloride is used in an amount of about 2% by weight based on the total weight, which is used as a curing time lasting agent to prevent the time of rapid curing before using the product. It is preferable to use about 8% by weight of the curing agent relative to the total weight.

It is preferable to use about 50% by weight of water, if less than that, the drying time is increased if less than that, resulting in a decrease in productivity, etc. If the weight is exceeded, there is a problem that it is difficult to mix with other mixtures.

It is preferable to use about 30% by weight relative to the total weight of the flame retardant, and use a flame retardant of an environmentally friendly material, and if less than 30% by weight, there is a problem in that it cannot serve as an auxiliary material to reinforce adhesive strength, and exceeds 30% by weight. If this happens, problems such as gas generation will occur.

Next, the manufacturing process of the styrofoam injected with the flame retardant of the present invention will be described with reference to FIG. 1.

The flame retardant injection device shown in FIG. 1 is a device for producing the present invention more effectively, and the present invention is not limited to this manufacturing method.

Looking at the manufacturing apparatus first, the manufacturing apparatus is a styrofoam 400, a plurality of injection needles 300 that are randomly embedded in the styrofoam 400, and the injection hose 210 connected to each of the plurality of injection needles 300 and , The injection branch pipe 200 to which the plurality of injection hoses 210 are connected, the connection pipe 110 connecting the injection branch pipe 200 and the high pressure atomizer 100, and a high pressure sprayer to inject flame retardant liquid at a high pressure. It consists of 100.

The injection needle 300 includes a connecting portion 320 connected to the injection hose 210 and a rod 310 having a passage hole 330 through which the injection liquid passes. The passage hole 330 has an inner diameter that allows the injection liquid to pass, and may be manufactured and used to have an inner diameter of about 1.0 mm. Rod 310 may be used as the outer diameter of 1.5 to 2mm and the size of the outer diameter is not important if it has an outer diameter of the degree of damage of the styrofoam 400.

The flame retardant composition described above is embedded in the high-pressure sprayer 100, and the flame-retardant liquid injected from the high-pressure sprayer 100 passes through the injection branch pipes 200 and the respective injection hoses 240 and the plurality of injection needles 300. It is injected into the styrofoam 400 through. Injected flame retardant liquid is spread evenly throughout the styrofoam 400 over time and continuous flame retardant injection.

Styrofoam in which the flame retardant solution is injected is dried in a dryer with a microweight, cured, and then cooled in a fan to complete the product.

The flame-retardant styrofoam prepared through this process was made into a sample (horizontal * vertical * thickness, 220 * 220 * 30mm) and given a constant firepower. No smoke was visible to the naked eye by the firepower lasting more than 1 minute. In addition, even if the generation of toxic gas confirmed by smell, it did not occur at all. After 10 minutes or more, a very small amount of toxic gas was released as an odor, which could be used as a non-flammable material in case of fire, and it could bring about the effect of reducing the bodily injury caused by toxic gas.

[Nonflammable Insulation Material Composition]

Non-flammable inorganic insulating material according to the present invention is a building material used as interior, exterior or ceiling of a building, soundproofing material, filling material.

Incombustible inorganic insulating material according to the present invention is a glass of NO ₂ to 870 ~ 900 ℃ Inorganic foam obtained by evaporating crystalline water by rapid heating with gas, and auxiliary materials stirred with water glass (Na ₂ 0 · SiO ₂ ), flame retardant, antimony and PVA (Polyvinyl acetate, polyvinyl acetate) were mixed and molded into a mold and thermoset. Are prepared.

In this case, the inorganic foam is a glassy rock containing crystallized water (about 3% to 5%) generated by rapid cooling of lava such as vermiculite, granite, or volcanic rock after crystallization. After rapid heating with ₂ gas, the crystal water is evaporated in the rapid heating process to expand the inorganic matter, turn white, and turn into an object that forms porous particles, and the object of the porous particles becomes an inorganic foam.

The inorganic properties thus obtained are ultra-light, maintain density 0.04 ~ 0.20g / m², have thermal conductivity 0.025 ~ 0.045kcal / mhc in terms of heat insulation, and have excellent heat insulation effect, do not change shape and quality, Melting temperature 1200 ℃ ~ 1300 / softening start 1100 ℃ In addition, it is excellent in chemical stability and no damage is caused by chemicals such as sulfuric acid, nitric acid, sodium hydroxide and the like. In addition, the hardness of 6.5 ~ 7.5 is very excellent, harmless to the human body or the environment, and has the advantage that no gas is generated during combustion.

An auxiliary agent is added to the inorganic foam thus produced, mixed, and cured through mold molding.

Here, the adjuvant to be added is water glass (Na ₂ O.SiO ₂ ), environmentally friendly flame retardant, antimony and polyvinyl acetate.

Here, the mixing ratio of the inorganic foam and the auxiliary agent is preferably stirred at 2: 1.

In addition, the mixing ratio of the auxiliary agent is preferably stirred at a ratio of 65 to 70% by weight of water glass (Na ₂ 0 · SiO ₂ ), 27.5 to 32.5% by weight of flame retardant, 2.48 to 3.0% by weight of antimony and 0.01 to 0.02% by weight of PVA. .

Water glass has a function as an adhesive / bonding agent, and if less than 65% by weight, the drying time is increased, resulting in a decrease in productivity, etc., and if it exceeds 70% by weight, there is a problem in that mixing with other mixtures is difficult.

The flame retardant is preferably used as an auxiliary material for reinforcing the adhesive strength of water glass, and if it is less than 27% by weight, there is a problem in that it does not serve as an auxiliary material for reinforcing the adhesive strength. Problems such as gas generation occur.

Antimony is mixed for the purpose of smoothing the surface treatment after curing. If less than 2.4% by weight, the surface of the heat insulating material may not be smoothed after curing, and if it exceeds 3.0% by weight, problems such as antimony-specific odor may occur. Occurs.

More preferably, stirring at a ratio of 67% by weight of water glass, 30% by weight of flame retardant, 2.975% by weight of antimony and 0.015% of PVA has a blending ratio which can maximize the effect according to the present invention.

The inorganic insulating material of the present invention and the conventional heat insulating material were cured after molding into a mold by mixing the adjuvant and the inorganic foam in a ratio of 67% by weight of water glass, 30% by weight of flame retardant, 2.975% by weight of antimony, and 0.015% of PVA. The content comparison is demonstrated with reference to Table 1.

As shown in Table 1, other insulation materials including the present invention except urethane foam are mostly flame retardant grade 1 materials, and in the nonflammable aspect, the flame retardant grade 1 material is partially flammable while the present invention is nonflammable.

In the generation of toxic gas that may occur in a fire, gypsum board, glass fiber, urethane foam, etc. generate toxic gas, but the present invention does not generate toxic gas and may play a role in preventing human life and property loss. have.

In terms of absorbency, gypsum board or glass fiber has a disadvantage of easily broken even in small moisture, but the present invention has excellent water absorbency and almost no deformation in water, and thus has strong water resistance.

In the case of the cement foam is almost the same properties as the present invention, the cement foam is not only a problem that the fatal volatile organic compounds occur in the human body as well as a high weight of the problem in terms of construction.

In addition, the present invention is to increase the tensile strength by about 80% by adding / curing by adding 0.015% by weight of polyvinyl acetate in the total ratio of the heat insulating material can be further improved the quality as a building heat insulating material.
