Further, from the viewpoint of the flame resistance of the resin itself, phenol resins and epoxy resins are preferred. The epoxy resin is not particularly limited, but is basically a resin obtained by reacting a monomer having an epoxy group with a curing agent.

Examples of the monomer having an epoxy group include bifunctional glycidyl ethers such as polyethylene glycol, polypropylene glycol, neopentyl glycol, 1,6-hexanediol, trimethylolpropane, and propylene oxide.

Examples of the catalyst type include polyamines, acid anhydrides, polyphenols and polymercaptans, and tertiary amines, imidazoles, Lewis acid complexes and the like. The curing method of these epoxy resins is not particularly limited, and can be performed by a known method.

Among the epoxy resins, those containing a long-chain alkyl or an epoxy resin having a long distance between cross-linking points, when used as a base resin, not only can maintain a low elastic modulus but also have a high carbonization rate and a high level of fire resistance. It is preferable because it can be maintained. Particularly, considering compatibility with a low elastic modulus, an epoxy resin to which flexibility is imparted by the following method is preferable.

(1) To increase the molecular weight between crosslinking points. (2) Reduce the crosslink density. (3) Introduce a soft molecular structure. (4) Add a plasticizer. (5) Introduce an interpenetrating network (IPN) structure. (6) Disperse and introduce rubber-like particles. (7) Introduce microvoids.

The above method (1) is a method in which a reaction is previously performed using an epoxy monomer having a long molecular chain and / or a curing agent, so that the distance between cross-linking points is increased and flexibility is exhibited. As the curing agent, for example, polypropylene diamine or the like is used.

The method (2) is a method in which a crosslink density in a certain region is reduced by using an epoxy monomer having a small number of functional groups and / or a curing agent to react, thereby exhibiting flexibility. For example, a bifunctional amine is used as a curing agent, and a monofunctional epoxy is used as an epoxy monomer.

The method (3) is a method in which an epoxy monomer having a soft molecular structure and / or a curing agent is introduced to exhibit flexibility. As the curing agent, for example, a heterocyclic diamine, and as the epoxy monomer, for example, an alkylene diglycol diglycidyl ether is used.

The method (4) is a method in which a non-reactive diluent such as DOP, tar or petroleum resin is added as a plasticizer.

The method (6) is a method in which liquid or granular rubber particles are mixed and dispersed in an epoxy resin matrix. Polyester ether or the like is used as the epoxy resin matrix.

The method (7) is a method in which microvoids of 1 μm or less are introduced into an epoxy resin matrix to exhibit flexibility. A polyether having a molecular weight of 1,000 to 5,000 is added as an epoxy resin matrix.

By adjusting the rigidity and flexibility of the epoxy resin, it is possible to form a flexible sheet from a hard plate-like material, and it can be applied to various parts requiring fire resistance.

Any of the above resins may be used alone, or a blend of two or more resins may be used to adjust the melt viscosity, flexibility, tackiness, etc. of the resin. Further, the resin composition of the present invention may be cross-linked or modified within a range that does not impair the fire resistance and sound insulation properties, and at the same time as the various fillers, additives, and the like used in the present invention are blended, the cross-linking and modification may be performed. Alternatively, crosslinking and modification may be performed after blending the above components with the resin. In this case, as a crosslinking method,
There is no particular limitation, and a usual crosslinking method of a resin, for example, a crosslinking method using various crosslinking agents, peroxides, and the like, a crosslinking method by electron beam irradiation, and the like can be used.

In the resin composition of the present invention, the above resin contains a thermally expandable inorganic substance and an inorganic filler having a true specific gravity of 3.0 or more. The performance of the fire-resistant sound insulating and damping resin composition of the present invention is exhibited when these components exhibit their respective properties. Specifically, the heat-expandable inorganic substance forms an expansion heat-insulating layer at the time of heating to prevent heat transmission. In addition, the inorganic filler imparts sound insulation and damping properties by contributing to an increase in the specific gravity of the resin composition.

The heat-expandable inorganic substance is a heat-expandable inorganic substance which expands when heated, and includes, for example, vermiculite, kaolin, mica, and heat-expandable graphite. Among these, heat-expandable graphite is preferred because of its low foaming start temperature.

Thermally expandable graphite is a conventionally known substance. Powders such as natural scale graphite, pyrolytic graphite and quiche graphite are mixed with inorganic acids such as concentrated sulfuric acid, nitric acid and selenic acid, concentrated nitric acid and perchloric acid. A crystalline compound that has been treated with a strong oxidizing agent such as perchlorate, permanganate, dichromate, hydrogen peroxide, etc. to produce a graphite intercalation compound, while maintaining a layered structure of carbon. It is.

The heat-expandable graphite obtained by the acid treatment as described above is preferably further neutralized with ammonia, an aliphatic lower amine, an alkali metal compound, an alkaline earth metal compound, or the like.

Examples of the aliphatic lower amine include, for example,
Monomethylamine, dimethylamine, trimethylamine, ethylamine, propylamine, butylamine and the like can be mentioned. As the alkali metal compound and the alkaline earth metal compound, for example, potassium, sodium,
Examples include hydroxides, oxides, carbonates, sulfates, and organic acid salts of calcium, barium, magnesium, and the like.

The particle size of the heat-expandable graphite is preferably from 20 to 200 mesh. When the particle size is smaller than 200 mesh, the degree of expansion of graphite is small, and a sufficient refractory and heat insulating layer cannot be obtained. When the particle size is larger than 20 mesh, there is an advantage that the degree of expansion of graphite is large. Or, when kneading with an epoxy resin, the dispersibility becomes poor, and a decrease in physical properties is inevitable.

As a commercially available product of the neutralized heat-expandable graphite, for example, "GR manufactured by UCAR CARBON"
AFGUARD "and" GREP-EG "manufactured by Tosoh Corporation.

The inorganic filler having a true specific gravity of 3.0 or more is not particularly limited as long as the true specific gravity is 3.0 or more. For example, barium sulfate (specific gravity 4.4, the same applies hereinafter), barium carbonate (4 .3), inorganic salts such as barium titanate (5.5), mica (3.0), titanium oxide (4.2), zinc oxide (5.4), iron oxide (5.2), zirconium oxide (5.5), metal oxides such as antimony oxide (5.7), aluminum oxide (3.8), magnesium oxide (3.3), iron (7.9), zinc (7.1), and lead (11.
3) and the like. These may be used alone or in combination of two or more.

The refractory resin composition of the present invention may further contain an antioxidant such as a phenol-based, amine-based or sulfur-based antioxidant, a metal harm inhibitor, an antistatic agent, and a stabilizer as long as the physical properties are not impaired. , A cross-linking agent, a lubricant, a softener, a pigment and the like may be added. Further, by adding a general flame retardant represented by a phosphorus-based flame retardant such as ammonium polyphosphate and an inorganic flame retardant such as aluminum hydroxide, the fire resistance can be improved by suppressing the combustibility.

In the resin composition of the present invention, the amount of the thermally expandable inorganic substance in the resin composition is preferably 20 to 400 parts by weight based on 100 parts by weight of the resin. If the amount of the heat-expandable inorganic substance exceeds 400 parts by weight, uniform dispersion becomes difficult, so molding with a uniform thickness becomes difficult. If the amount is less than 20 parts by weight, the thickness of the sheet increases in order to obtain sufficient fire resistance. Needs to be increased, in which case the handling of the sheet material becomes poor. The amount of the inorganic filler having a true specific gravity of 3.0 or more is preferably 50 to 500 parts by weight based on 100 parts by weight of the resin. When the compounding amount of the inorganic filler exceeds 500 parts by weight, the fluidity at the time of molding the resin composition is poor, and molding of a sheet or the like becomes difficult. Sufficient specific gravity cannot be secured.

The resin composition used in the present invention can be obtained by kneading the above components using a known kneading device such as a Banbury mixer, a kneader mixer, or a two-roll mill. The heat-expandable refractory sheet is obtained by molding the above resin composition into a sheet or the like by a conventionally known molding method such as hot press molding, extrusion molding, or calendar molding.

The fire-resistant sound-insulating and damping resin composition used in the present invention has a specific gravity of 1.5 or more. If the specific gravity is less than 1.5, a sufficient sound insulation effect cannot be obtained.

The fire-resistant sound-insulating and damping resin composition used in the present invention has a tensile modulus of 0.3 to 50 MPa with a No. 2 dumbbell according to JIS K6301. If the tensile modulus is less than 0.3 MPa, it is difficult to handle and construct,
If it exceeds 50 MPa, the sound insulation performance will decrease. In addition, it is preferable that the value of Tan δ when the dynamic viscoelasticity is measured at room temperature is 1 or more in the fire-resistant sound-insulating and damping resin composition used in the present invention because the sound-insulating and damping performance is further improved.

When the fire-resistant and sound-insulating and damping resin composition has the above specific gravity and elastic modulus, transmitted sound on a general surface can be reduced. This is because sound propagation occurs when a material transmits vibration, and when the specific gravity of the material increases, the vibration is reduced. Also, when the elastic modulus of the material is high, there is an effect of reducing vibration.

Further, in the sheet shape of the fire-resistant sound-insulating and damping resin composition used in the present invention, the thickness changes when irradiated with a heat of 50 kW / m ² for 30 minutes (thickness D after irradiation).
1 / Thickness before irradiation D0) is 1.1 to 100 times.
If the thickness change is less than 1.1 times, the fire resistance is insufficient, and if it exceeds 100 times, the strength of the fire-resistant heat-insulating layer formed by expansion due to heating is reduced, and the layer is liable to collapse.

The fire-resistant sound insulating and damping resin composition of the present invention comprises:
The heat-expandable inorganic substance expands due to the heat of a fire, etc., and the combustion residue forms a fire-resistant heat-insulating layer. This heat-insulating layer can suppress the rise in temperature, reduce the sound transmitted through the general surface, and propagate the solid. Since the vibration noise can be reduced by attenuating the vibration, it can be used as various building materials.
