Description

  The present invention relates to a fireproof structure for a resin sash.

Conventionally, a sash has been used as a building member installed in an opening or the like of a structure such as a house.
When a fire occurs inside or outside a structure such as a house, it is necessary to prevent the fire from spreading. Increasing the fire resistance of the sash is an important issue so that a fire flame or the like does not spread through the sash.
In connection with this problem, a technique for improving the fire resistance of a sash has been proposed.
Specifically, for a sash provided with a frame material made of synthetic resin and a fire-resistant plate material, a plurality of hollow portions are provided in the longitudinal direction of the frame material used for the sash, and in this hollow portion There has been proposed a fireproof structure of a resin sash in which a metal member having a substantially U-shaped or square pipe shape is inserted, and a plate-like thermally expandable refractory material is bonded to the metal member (Patent Document) 1).
With this resin sash fireproof structure, even if the resin sash fireproof structure is exposed to the heat of a fire or the like since the metal member is inserted into the frame material, A plate material having fire resistance such as glass contained in the structure can be supported. Further, since the thermally expandable refractory material inserted inside the frame material expands due to heat such as a fire to form an expansion residue, there is a gap between the fire resistant plate material such as glass and the wall or the like. It is said to be excellent in fire resistance because it is blocked.
However, in the case of the conventional fireproof structure of the resin sash, the metal member must be installed inside the frame member, so that the productivity of the resin sash per unit time is inferior, and the resin including the metal member Since the weight of the sash is increased, there is a problem that handling of the resin sash is not easy.

On the other hand, a fireproof structure of a resin sash that does not use the metal member has been proposed (Patent Document 2).
Specifically, for a sash provided with a frame material made of synthetic resin and a fire-resistant plate material, a plurality of hollow portions are provided in the longitudinal direction of the frame material used for the sash, and flow into the hollow portion. A fireproof structure of a resin sash that is solidified by injecting a heat-expandable refractory material has been proposed.
This resin sash fireproof structure is excellent in resin sash productivity because no metal member is used, and the resin sash is lightweight and easy to handle, as seen in the previous fireproof structure of a conventional resin sash. No problem arises.

  The nitrogen compound is not particularly limited, but is preferably a melamine compound or the like. The alcohols are not particularly limited, but polyhydric alcohols such as pentaerythritol are preferable.

  When the inorganic filler used in the present invention is granular, the particle size is preferably in the range of 0.5 to 200 μm, more preferably in the range of 1 to 50 μm.

  When the amount of the inorganic filler added is small, the dispersibility greatly affects the performance, so a small particle size is preferable. However, when the particle size is 0.5 μm or more, secondary aggregation can be prevented and the dispersibility is good. It becomes.

  In addition, when the amount of inorganic filler added is large, the viscosity of the resin composition increases and moldability decreases as high filling proceeds, but the viscosity of the resin composition is decreased by increasing the particle size. From the point of being able to do, the thing with a large particle size is preferable among the said range.

  In addition, when a particle size is 200 micrometers or less, it can suppress that the surface property of a molded object and the mechanical physical property of a resin composition fall.

  It is considered that the combined use of the hydrated inorganic substance and the metal carbonate greatly contributes to improving the strength of the combustion residue and increasing the heat capacity.

  Among the inorganic fillers, in particular, water-containing inorganic substances such as aluminum hydroxide and magnesium hydroxide are endothermic due to the water generated by the dehydration reaction during heating, and the temperature rise is reduced and high heat resistance is obtained. This is preferable in that the oxide remains as a combustion residue and this acts as an aggregate to improve the strength of the combustion residue.

  Magnesium hydroxide and aluminum hydroxide have different temperature ranges that exhibit dehydration effects, so when used together, the temperature range that exhibits dehydration effects becomes wider, and more effective temperature rise suppression effects can be obtained. It is preferable to do.

  When the particle size of the water-containing inorganic substance is small, the bulk increases and it becomes difficult to achieve high filling. Therefore, in order to increase the dehydration effect, a large particle size is preferable.

  Specifically, it is known that when the particle size is 18 μm, the filling limit amount is improved by about 1.5 times compared to the particle size of 1.5 μm.

  Further, by combining a large particle size and a small particle size, higher packing can be achieved.

  As a commercial item of the said water-containing inorganic substance, for example, as aluminum hydroxide, “trade name: Hygielite H-42M” (manufactured by Showa Denko) with a particle diameter of 1 μm, “trade name: Hygilite H-31 with a particle diameter of 18 μm”. (Made by Showa Denko KK) and the like.

  Examples of commercially available calcium carbonate include “trade name: Whiten SB red” (manufactured by Shiraishi Calcium Co., Ltd.) having a particle size of 1.8 μm, and “trade name: BF300” (manufactured by Bihoku Flour & Chemical Co., Ltd.) having a particle size of 8 μm. Etc.

  As explained at the beginning, as the heat-expandable refractory material used in the present invention, the resin composition containing the above-described reaction-curable resin resin component, heat-expandable component, inorganic filler, etc., and the above-mentioned phosphorus compound Examples of these compounds are described below.

  The thermally expandable refractory material preferably contains 5 to 100 parts by weight of the reactive curable thermal expansion component and 10 to 200 parts by weight of the inorganic filler with respect to 100 parts by weight of the reactive curable resin component. .

  The total of the reactive curable thermal expansion component and the inorganic filler is preferably in the range of 20 to 300 parts by weight.

  Such a thermally expandable refractory material expands due to heat from a fire or the like to form a thermally expanded residue. According to this composition, the heat-expandable material is expanded by heat such as a fire, and a necessary volume expansion coefficient can be obtained, and after expansion, a thermal expansion residue having a predetermined heat insulation performance and a predetermined strength. Can be formed, and stable fire resistance can be achieved.

When the amount of the reactive curable thermal expansion component is 10 parts by weight or more, the necessary expansion ratio can be obtained, so that sufficient fire resistance and fire prevention performance can be obtained.
On the other hand, the fluidity | liquidity in 25 degreeC of the said thermally expansible refractory material can be ensured as the quantity of the said thermal expansion component is 150 weight part or less.

Further, when the amount of the inorganic filler is 50 parts by weight or more, there is little volume reduction of the thermal expansion residue after combustion, and a thermal expansion residue for fireproof insulation is obtained.
Furthermore, since the ratio of combustible material increases, flame retardancy may decrease.

  On the other hand, the fluidity | liquidity in 25 degreeC of the said thermally expansible refractory material can be ensured as the quantity of an inorganic filler is 300 weight part or less.

  When the total amount of the thermal expansion component and the inorganic filler in the thermally expandable refractory material is 60 parts by weight or more, the amount of the thermal expansion residue after combustion is not insufficient, and sufficient fire resistance can be easily obtained. Deterioration of physical properties is small and suitable for actual use.

  Furthermore, the thermally expandable refractory material used in the present invention is a plasticizer such as phthalic acid ester, adipic acid ester, phosphoric acid ester, phenolic, amine, etc., as long as the object of the present invention is not impaired. -Based, sulfur-based antioxidants, heat stabilizers, metal damage inhibitors, antistatic agents, stabilizers, cross-linking agents, lubricants, softeners, pigments, tackifier resins, additives, polybutene, petroleum resins Such as tackifier, glass powder, amorphous silica, microgel, castor oil wax, amide wax and the like.

The viscosity at 25 ° C. of the thermally expandable refractory material used in the present invention is preferably in the range of 1000 to 100,000 mPa · s based on the value before being injected into the resin frame hollow portion.
When the viscosity is 1000 mPa · s or more, the thermally expandable refractory material can be easily filled even in a narrow gap in the hollow portion of the resin frame material. In addition, the pressure for injecting the thermally expandable refractory material into the resin frame material hollow portion, the pressure of the injection device, and the like do not become higher than necessary, and injection can be performed easily.
When the viscosity is 100,000 mPa · s or less, it is difficult to entrain air when the thermally expandable refractory material is injected into the resin frame material hollow portion, and it becomes easy to inject a desired filling amount. In addition, since each component of the thermally expandable refractory material is difficult to separate during injection and can be prevented from becoming non-uniform, the composition of the thermally expandable refractory material is kept uniform in the resin frame hollow portion. And the desired fire resistance can be exhibited.
The viscosity is more preferably in the range of 2,000 to 100,000 mPa · s, and even more preferably in the range of 3000 to 100,000 mPa · s.

  Adjustment of the viscosity of the said thermally expansible refractory material can be adjusted by selecting the kind etc. of the reaction curable resin component of the thermally expansible refractory material used for this invention. By selecting a liquid reaction curable resin component having a low viscosity at 25 ° C., the viscosity of the thermally expandable refractory material at 25 ° C. can be reduced. Conversely, by selecting a liquid reactive curable resin component having a high viscosity at 25 ° C., the viscosity of the thermally expandable refractory material at 25 ° C. can be increased.

The viscosity of the thermally expandable refractory material can also be adjusted by changing the weight ratio of the thermal expansion component and the inorganic filler contained in the thermally expandable refractory material.
For example, the viscosity of the thermally expandable refractory material at 25 ° C. can be reduced by reducing the weight ratio of the thermally expandable component, inorganic filler, etc. contained in the thermally expandable refractory material. In addition, the viscosity can be reduced by appropriately selecting a liquid inorganic filler at a temperature of 25 ° C.
Conversely, increasing the weight ratio of the thermal expansion component, inorganic filler, and the like contained in the thermally expandable refractory material can increase the viscosity of the thermally expandable refractory material at 25 ° C.

The thermal expansion start temperature and the thermal expansion ratio of the thermally expandable refractory material can be changed by adjusting the thermal expansion start temperature and the thermal expansion ratio of the thermally expandable graphite contained in the thermal expandable refractory material, respectively. .
Since thermally expandable graphite having different thermal expansion start temperature and thermal expansion ratio is commercially available, the desired thermal expansion start temperature can be selected by selecting the desired thermal expansion start temperature and thermal expansion graphite having the thermal expansion ratio. And the said thermally expansible refractory material with a thermal expansion magnification is obtained.

Next, the manufacturing method of the said thermally expansible refractory material is demonstrated.
The method for producing the thermally expandable refractory material is not particularly limited. For example, a method of suspending the thermally expandable refractory material in an organic solvent, or heating and melting it to form a paint, a solvent In the case where a component that is a solid at 25 ° C. is included in the reaction curable resin component contained in the thermally expandable refractory material, such as a method of preparing a slurry by dispersing, the thermally expandable refractory material is used. The resin composition can be obtained by a method such as melting under heating.

  For the thermally expandable refractory material, each component of the thermally expandable refractory material is a known apparatus such as a single-screw extruder, a twin-screw extruder, a Banbury mixer, a kneader mixer, a kneading roll, a raikai machine, and a planetary stirrer. And kneading.

In addition, the main agent having a reactive functional group such as isocyanate group and epoxy group and the curing agent may be kneaded separately together with a filler, and kneaded with a static mixer, a dynamic mixer or the like immediately before injection. .
Further, the components of the heat-expandable refractory material excluding the catalyst and the catalyst can be kneaded in the same manner immediately before injection.

  By the method described above, the thermally expandable refractory material used in the present invention can be obtained.

Since the thermally expandable refractory material obtained as described above has fluidity at a temperature of 25 ° C., it can be injected into the hollow portion of the resin frame material.
Here, having fluidity means that the thermally expandable refractory material does not have a certain shape when left standing, and has no fluidity, means that the thermally expandable refractory material is left standing. A case having a certain shape.

The heat-expandable refractory material is not particularly limited as long as it is thermally insulated by the expansion layer when exposed to a high temperature such as a fire, and has the strength of the expansion layer, but is heated at 600 ° C. for 30 minutes. It is preferable if the volume expansion coefficient after heating under conditions is in the range of more than 1 to 5 times.
When the volume expansion rate is less than 1 time, the expansion volume may not be able to fully fill the burned-out portion of the resin component, and fire prevention performance may be reduced. On the other hand, if it exceeds 5 times, the strength of the expansion layer is lowered, and the effect of preventing the penetration of the flame may be lowered. More preferably, the volume expansion coefficient is in the range of 1.2 to 5 times, and more preferably in the range of 1.3 to 4 times.

In order for the expansion layer to be self-supporting, the expansion layer needs to have a high strength. As the strength, the sample of the expansion layer is set to 0 using a 0.25 cm ² indenter in a compression tester. It is preferable that the stress at break when measured at a compression speed of 0.1 m / s is 0.05 kgf / cm ² or more. If the stress at break is less than 0.05 kgf / cm ² , the adiabatic expansion layer may not be self-supporting and the fireproof performance may be reduced. More preferably, it is 0.1 kgf / cm ² or more.

It adjusted so that it might become.

Next, the viscosities of component A and component B were measured. The viscosity was measured at 25 ° C. using a B-type rotary viscometer (manufactured by Viscotec).

When the test piece is carefully heated, it can be confirmed that the test piece starts to expand. The temperature at which this expansion can be confirmed with the naked eye is the thermal expansion start temperature.
