る。Detailed Description of the Invention The present invention relates to a water-soluble or water-dispersible thermosetting resin (hereinafter simply referred to as a hydrophilic thermosetting resin).
The present invention relates to a mechanical floss foaming machine suitable for producing foam with improved processing capacity and high expansion ratio.

いる。 Synthetic resin foam has excellent performance as a heat insulating material, and is expected to be in great demand due to the need to save energy and resources. Furthermore, from the perspective of resource conservation, there is an increasing demand for foams with a high expansion ratio.

分を生じる等トラブルの原因となり易い。 Conventional methods for producing highly foamed materials include resin foam raw materials, curing agents, and blowing agents that are liquid at room temperature and pressure but vaporize as the temperature rises, or liquid under pressure but gaseous at room temperature and pressure. A common method was to mix a certain blowing agent (hereinafter simply referred to as a liquid blowing agent) and then foam and harden the mixture. However, this method has the disadvantage that in order to increase the expansion ratio, it is necessary to use a large amount of foaming agent, which increases the cost of producing the foam. In addition, when producing foam using a liquid foaming agent, quality control is difficult because the foaming rate varies depending on the temperature of the atmosphere, and unfilled areas may occur, especially when the interior space of residential panels is divided by crosspieces, etc. This can easily cause problems.

熱硬化樹脂に対する要望は大である。 On the other hand, hydrophilic thermosetting resins can be foamed using air as a foaming agent, and in this method, there is almost no volumetric expansion after discharge from a foaming machine, making quality control easy. There is a great demand for hydrophilic thermosetting resins because they use air as a blowing agent, so they are inexpensive to manufacture and have good workability.

As shown in Figure 2, when increasing the tube diameter, the density of the obtained foam decreases, reaches the lowest point, and then increases further. A trend was observed, and it was found that the lower limits of foam density were almost the same. Furthermore, it has been found that when a discharge tube in which the cross-sectional area S of the tube is larger at the tip than at the discharge port is used, the resulting foam density is further reduced below the above-mentioned lower limit.
(Note that A is a small pipe diameter, B is a medium-large pipe diameter, and C is a large pipe diameter, where the solid line shows the conventional pipe and the broken line shows the enlarged discharge pipe.)

れるものではない。 Furthermore, as a result of research, especially when the internal pressure of the mechanical floss foaming machine is 3Kg/cm 3 or more in gauge pressure, S 2 /S 1 is S 1 when the cross-sectional area of the foaming machine's discharge port is S 1 and the cross-sectional area of the tip is S 2 . When it is 1.5 times or more, preferably 2 times or more and 5 times or less, the pressure drop is smooth and a high expansion ratio can be obtained. For example, S 2 /S 1 is 1.7 times, 2.3 times, and 4.0
When doubled, the foam density decreased to 86%, 72%, and 65%, respectively, compared to when the enlarged discharge port was not used, and a highly foamed product was achieved. The expansion and length of the piping can be freely adjusted depending on the amount of foam raw material processed and the distance from the discharge port to the panel, but if the internal pressure of the mechanical floss foaming machine is 3.
It is necessary to maintain a predetermined pressure of Kg/cm 3 G or more and to make the foam flow continuously. Preferred embodiments of the enlarged discharge tube are listed in FIGS. 3 to 5.
Fig. 3 shows the case where it expands into a canal of Rappa, Fig. 4 shows the case where it expands stepwise, and Fig. 5 shows the case where it branches. In the case of a branched type, the total cross-sectional area of the tube tip is
