Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin composition for fire joints. 2. Description of the Related Art In recent years, there has been an increasing number of cases where members of the inner and outer walls of general buildings are required to have fire resistance and fire prevention performance. Generally, as a base material of the joint material, for the purpose of watertightness, airtightness, silicone-based, modified silicone-based, polysulfide-based, polyesterpolyol-based resins, ethylene / α-olefin copolymers, etc. are widely used.
Most of these materials are flammable, and there is a problem that the fire spreads more easily at the joints during a fire. Accordingly, inorganic materials such as mortar, gypsum, and water glass are often used to seal the joints of fire-resistant members used for interior panels and partitions for the purpose of fire resistance and fire prevention performance. However, these materials have problems that shrinkage during the curing process is unavoidable, and that the hardness after curing is extremely high, causing cracks and interfacial destruction in a short period of time. Further, in a high-rise building that emphasizes interlayer displacement and followability, since the joint is movable to absorb the displacement, the inorganic material cannot be used, and a fireproof sound insulation is provided as a complicated structure. [0004] In order to solve the above problems, for example, Japanese Patent Application Laid-Open No. 63-92690 discloses a method in which an organosilane, a metal hydroxide, and a silanol condensation catalyst are added to a polyether polymer to provide a fireproof. And a sealant composition having improved fire prevention performance. However, in this sealant composition, although cracks are improved, there is a problem that sufficient performance is not obtained in fire resistance, fire resistance, and the like. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described drawbacks, and has as its object to provide excellent fire resistance and fire protection, as well as water tightness, air tightness, water resistance, and durability. It is to provide a resin composition for a fire joint material excellent in the above. [0006] The resin composition for fireproof joint material of the present invention comprises a silicone resin and a modified silicone resin.

Ru one carbon-containing polymeric material der selected from the group. The carbon-containing polymer material may be a moisture-curable one-component system or a reaction-curable two-component system. The shape of the joint material used is not particularly limited. There is no particular limitation on the depth, width, and the like. The neutralized thermal expansion used in the present invention
As the tonic graphite, a conventionally known heat-expandable graphite can be neutralized.
Can be used, as the heat-expandable graphite, for example, natural flaky graphite, pyrolytic graphite, powder such as quiche graphite, concentrated sulfuric acid, nitric acid, inorganic acids such as selenic acid and concentrated nitric acid, perchloric acid, perchlorate, permanganate, dichromate, treated with a strong oxidizing agent such as hydrogen peroxide which was to produce a graphite intercalation compound, include crystalline compound which remains maintaining the layered structure of the carbon Can be The neutralized thermally expandable graphite of the present invention
Is the heat-expandable graphite obtained by the above acid treatment,
Monia, aliphatic lower amine, alkali metal compound, Al
Thermal expansion obtained by neutralization with potassium earth metal compound
It is graphite. As the aliphatic lower amine, for example,
Monomethylamine, dimethylamine, trimethylamine
, Ethylamine, propylamine, butylamine, etc.
And the above alkali metal compounds and alkaline earths.
Potassium, sodium, calcium
Hydroxide, oxide, charcoal such as
Acid salts, sulfates, organic acid salts and the like. The neutralized heat-expandable graphite is 80
The volume expansion coefficient when rapidly heated to 0 ° C or higher is small
If this happens, it will not be possible to obtain sufficient flame retardancy.
Restricted above. The volume expansion rate of 100 times or more is as follows
Was evaluated by the following method. That is, the internal volume is 100 milliliters
Put 1 ml of heat-expandable graphite into a platinum crucible,
It is put into an electric furnace preheated to 800 ° C. or higher. Input
After 30 seconds, remove the platinum crucible and let it cool to room temperature.
Allowed to cool until Thermal expansion black expanded by heating
Lead must be at least enough to completely fill the crucible volume
Determined that the volume expansion rate was 100 times or more. When the particle size of the heat-expandable graphite is too small, the degree of expansion of the heat-expandable graphite is small and sufficient flame retardancy cannot be obtained. When the particle size is too large, the dispersibility is poor when mixed and kneaded with a resin. Since the physical properties of the obtained molded article are deteriorated,
200 mesh is preferred. The phosphorus compounds used in the present invention include:
Phosphate esters such as triphenyl phosphate, octyl diphenyl phosphate, trioctyl phosphate, tricresyl phosphate; metal phosphates such as sodium phosphate, potassium phosphate, magnesium phosphate, zinc phosphate, aluminum phosphate and the like Hydrates of metal salts; salts of phosphoric acid such as ammonium phosphate, ammonium polyphosphate, phosphate of ethylenediamine, phosphate of diethylenetriamine, etc. with ammonia or amines or condensates thereof, and phosphoric acid of guanidine Salts, phosphines, phosphine oxides, phosphones such as t-butylphosphone and phenylphosphone, melamine-modified ammonium polyphosphate, red phosphorus and the like, which may be used alone or in combination of two or more. Good. Among the above phosphorus compounds, ammonium polyphosphate is particularly preferred because it is easy to handle and excellent flame retardancy is obtained. In the resin composition of the present invention, the mixing ratio between the heat-expandable graphite and the phosphorus compound is 1: 9 to 9:
1 is preferred. When the mixing ratio is out of the range, there is no significant difference in the flame retardancy between the case where the thermally expandable graphite and the phosphorus compound are used alone. [0015] If necessary, a hydrated metal oxide may be added to the resin composition as a flame retardant aid. Examples of the hydrated metal oxide include aluminum hydroxide, magnesium hydroxide, dawsonite and the like. Further, if necessary, calcium carbonate, silicate, glass fiber, asbestos, talc, kaolin, mica, metal oxide, and the like may be added to the resin composition as a filler or a reinforcing agent. These may be used alone or in combination of two or more. The resin composition for a fireproof joint material of the present invention may be produced by any of a conventionally known continuous production method and a batch production method. Embodiments of the present invention will be described below.
