(Industrial Application Field) The present invention relates to a foamable composition, particularly for use in areas where it comes into contact with the exterior walls of prefabricated houses or the steel plates of wall panels, or within a frame made of steel material of a wall panel. The present invention relates to sexual compositions. (Prior Art) Conventionally, as this type of heat insulating material, one obtained from a foamable composition containing a phenol resin as a main component and using Freon as a foaming agent is known (for example, Japanese Patent Application Laid-Open No. 1989-1992). (See Publication No. 47564). Phenolic resins are flame retardant, have good weather resistance, have high mechanical strength, and are relatively elastic.
Furthermore, it is known to have excellent properties as a base material for heat insulating materials, such as good thermal and electrical insulation and water resistance. Generally, such foamable compositions containing phenolic resin as a main component include:
Acid catalysts such as phenolsulfonic acid have been used to cure phenolic resins to produce heat insulating materials. On the other hand, Freon used as a blowing agent is usually Freon 11 (gaseous at room temperature), Freon 12 (gaseous at room temperature), or Freon 22 (gaseous at room temperature) and Freon 113 (boiling point
47.6℃). In addition, as a blowing agent other than Freon, for example, JP-A-56-
Publication No. 30438 discloses many types of blowing agents. (Problems to be Solved by the Invention) However, in the foamed composition described above, the acid catalyst such as phenolsulfonic acid remains even after the heat insulating material is formed. Therefore, when installing the insulation material obtained in this way in a place where it will come into contact with other metal members such as a frame made of steel or iron plates of a wall panel, or inside the steel frame of a wall panel, , the metal member will be corroded by the heat insulating material. In order to prevent this, it is possible to apply anti-rust paint containing zinc powder or the like to the metal material to prevent rust and then install insulation material, but in this case work efficiency will deteriorate. I will do it. That is, a coating process for applying a rust-preventing paint to the metal material is required, resulting in inconveniences such as increased construction costs. In addition, the heat insulating material must be installed after the applied anti-rust paint has completely dried, resulting in inconveniences such as time-consuming installation. Therefore, it has been desired to provide a heat insulating material that can be installed at low cost and in a short period of time and has excellent corrosion prevention properties. On the other hand, the above Freon is relatively expensive. In addition, even if a foaming agent other than Freon is used, it can maintain its excellent performance as a heat insulating material.
It has been difficult to provide inexpensive insulation materials. Therefore, it has been desired to use a single foaming agent and to provide an inexpensive heat insulating material using as little amount as possible. The present invention was made in view of the actual situation,
The purpose of the present invention is to provide a foamable composition that has excellent corrosion prevention performance even when installed in a frame made of steel for a wall panel, and can be used to produce an inexpensive heat insulating material. (Means for Solving the Problems) The foamable composition used for the wall panel of a house according to the present invention is a resol type phenol with a pH of 7.0 to 8.0.
Aldehyde polycondensate 65-80% by weight, phenolsulfonic acid 10-16% by weight, silicone 0.2-80%. 0.7% by weight, 4.5-12.0% by weight of methylene chloride as a foaming agent, and 3.5-6.5% by weight of zinc dust as a corrosion inhibitor. It is installed in a place like this, or inside a frame made of steel on a wall panel. (Example) Hereinafter, an example of the present invention will be described. The foamable composition used for the wall panel of the house according to the present invention is a resol type phenol with a pH of 7.0 to 8.0.
Aldehyde polycondensate 65-80% by weight, phenolsulfonic acid 10-16% by weight, methylene chloride 4.5-12.0%
wt%, zinc powder 3.5-6.5 wt%, silicone 0.2
~． Consisting of 0.7% by weight. That is, the foamable composition used for the wall panel of the house of the present invention has the concentrations of the resol-type phenol-aldehyde polycondensate, phenolsulfonic acid, methylene chloride, zinc dust, and silicone within the numerical ranges mentioned above. If the phenol resin is less than 65% by weight, the mechanical strength of the resulting molded product is too low and is unsuitable as a heat insulating material, and if it is more than 80% by weight, the molding processability is poor. Become. Further, the initial pH of the resol type phenol-aldehyde polycondensate is adjusted to a range of 7.0 to 8.0. Phenolsulfonic acid is a curing agent, and if it is less than 10% by weight, the resol type phenol-aldehyde polycondensate will not be completely cured. Also, 16% by weight
In this case, the curing time is short and not only is it impossible to obtain a molded product of appropriate dimensions, but also the density of the obtained molded product becomes too high, making it unsuitable as a heat insulating material. Methylene chloride is a blowing agent, and if it is less than 4.5% by weight, molded products of constant dimensions cannot be obtained, and in particular, only molded products with non-uniform width or thickness can be obtained. If it exceeds 12.0% by weight, the foaming density becomes too high and the surface of the molded product becomes rough. Furthermore, the density of the molded product is too low to be used as a heat insulating material. Since phenolsulfonic acid remains even after molding, when the obtained heat insulating material comes into contact with other metal members such as iron plates during the construction stage, it corrodes these metal members. For this reason, zinc powder is blended, but if it is less than 3.5% by weight, it is ineffective, and if it is more than 6.5% by weight, the resulting molded product will have a significantly low bending strength and compressive strength. Silicone is blended to uniformly disperse the air bubbles in the molded product, but if it is less than 0.2% by weight, it has no effect, and if it is more than 0.7% by weight, the closed cell ratio in the molded product decreases, and the bending strength and Not only does its compressive strength decrease, but its water absorption also increases, making it unsuitable for use as a heat insulating material. As resol-type phenol-aldehyde polycondensates, resol-type resins obtained from phenolic resins (phenol, cresol, xylenol, resorcinol, etc.) and aldehydes (formaldehyde, tesetaldehyde, furfural, etc.) and their modified resins are used to adjust the pH. It can be used as As phenolsulfonic acid, o-, m-,
Any p-phenolsulfonic acid can be used. Next, specific examples of the present invention will be shown, but these specific examples do not limit the present invention. Note that parts indicate parts by weight. [Specific example] Resol type phenol-aldehyde polycondensate (trade name Fol-63, manufactured by Showa Union Gosei Co., Ltd.,
100 parts of fixed component concentration (76% by weight), 20 parts of phenolsulfonic acid (manufactured by Daiichi Kogyo Seiyaku Co., Ltd., purity 67% by weight), 10 parts of methylene chloride, 5 parts of zinc powder, and silicone (trade name: Silicone F-258, (manufactured by Shin-Etsu Chemical Co., Ltd.) to prepare a foamable composition. The foamable composition thus obtained was melted at 40 to 70°C to obtain a heat insulating material. [Comparative Examples 1 to 4] Instead of 10 parts of methylene chloride, 10 parts of Freon (mixture of Freon 11 and 113, mixing ratio 1:1)
A foamable composition was prepared in the same manner as in the above specific example except that 15 parts, 20 parts, and 25 parts were used. The foamable composition thus obtained was melted at 40 to 70°C to obtain a heat insulating material. Next, an experiment was conducted to compare the performance of the heat insulating materials obtained in these specific examples and comparative examples 1 to 4. [Experimental example] The (1) density, (2) compressive strength, (3) bending strength, (4) water absorption, and (5) thermal conductivity of the heat insulating materials obtained in the above specific examples and comparative examples 1 to 4 were determined. We measured and compared. The results are shown in Table 1. The method for measuring each performance is shown below. (1) Density: 100 test pieces with a thickness of 40 mm, a width of 100 mm, and a length of 100 mm.
It was completely dried at ±5°C, and the weight W and volume V at that time were measured and calculated from the following formula. Density (g/cm 3 ) = W/V (2) Compressive strength A test piece with a thickness of 40 mm, width of 50 mm, and length of 50 mm is sandwiched between a parallel plane table and an upper plate, and a constant load is gradually applied to determine the maximum load. . (3) Bending strength Both ends of a test piece with a thickness of 40 mm, width of 75 mm, and length of 300 mm were placed on a stand arranged in two rows at the same height, and a load was gradually applied to the entire width of the center of the test piece to bend it. Strength K
(Kg/cm 2 ) was determined. K=3Wl/2bh 2 W: Maximum load (Kg) l: Length of test piece (cm) b: Width of test piece (cm) h: Thickness of test piece (cm) (4) Water absorption rate Thickness: 25 mm, A test piece of width 100mm and length 23±
The sample was immersed in a constant temperature bath at 3°C, and the standard weight and the weight after final water absorption were measured to determine the water absorption rate A (gr/100cm 2 ). A = (B-C)/Surface area x 100 B: Standard weight (g) - After immersing for 10 seconds, the mesh opening is approximately 3 mm
C: Weight after final water absorption (g) - Weight measured in the same manner as the reference weight after immersion for 24 hours (5) Heat conduction JIS test specimen with a thickness of 25 mm, width of 100 mm, and length of 100 mm
- Measured by the method specified in A-1412.

Further, this heat insulating material is installed in a place where it comes into contact with a steel plate of a wall panel, or inside a frame made of a steel material of a wall panel. (Effects of the Invention) As described above, according to the present invention, by using zinc powder as a corrosion inhibitor, it is possible to provide a heat insulating material that has a corrosion inhibiting effect and has excellent performance. , even if it is installed in a place where it comes into contact with other metal parts such as the steel plate of a wall panel, or within the steel frame of a wall panel.
Will not corrode metal parts. Therefore, there is no need for a conventional coating process in which rust-preventing paint is applied to metal members to prevent corrosion, and construction costs can be reduced. Also,
It also eliminates the need for time to dry the applied anti-rust paint, allowing the resulting insulation material to be installed in a short time. Furthermore, the cost of raw materials can be reduced by using inexpensive methylene chloride as a blowing agent.
