Problems solved by technology

In particular, heat insulating materials with an oxygen index of 26% by volume or less are designated combustibles, so there is a problem that their storage places and storage methods are restricted.
Furthermore, when a fire breaks out in a building constructed with the aforementioned heat insulating material, there is a problem that the heat insulating material will increase the spread speed of the flame.

Embodiment 1

[0125] Manufacture of phenolic resin foam

[0126] 50% by mass and 50% by mass of ethylene oxide-propylene oxide block copolymers and polyoxyethylene dodecylphenyl ether compositions as surfactants with respect to 100 parts by mass of phenolic resin Raw material A was mixed in a ratio of 3.0 parts by mass. 11 parts by mass of 1-chloro-3,3,3-trifluoropropene as a foaming agent and 14 parts by mass of A mixture of 80% by mass of xylenesulfonic acid and 20% by mass of diethylene glycol as an acid curing catalyst. The foamable phenolic resin composition as the final mixture is dispensed from a branch pipe, and supplied onto the moving surface material.

[0127] The surface opposite to the surface contacting the surface material of the foamable phenolic resin composition on the surface material is covered with another surface material, and the foamable phenolic resin composition is sandwiched between the two surface materials. In this state, the foamable phenolic resin compositi...

Embodiment 2

[0130] The foaming agent was changed to 1,3,3,3-tetrafluoro-1-propene, and 8 parts by mass of the aforementioned foaming agent was added to 100 parts by mass of the mixture of the surfactant and the phenolic resin raw material. Example 1 was carried out in the same manner to obtain a phenolic resin foam.

Embodiment 3

[0132] The foaming agent was changed to 1,1,1,4,4,4-hexafluoro-2-butene, and 14 parts by mass of the aforementioned foam was added to 100 parts by mass of a mixture of a surfactant and a phenolic resin raw material. Except for the foaming agent, it carried out similarly to Example 1, and obtained the phenolic resin foam.

Abstract

Provided is a phenol resin foam body which comprises a phenol resin and a foaming agent that includes a chlorinated hydrofluoroolefin and / or a non-chlorinated hydrofluoroolefin. The phenol resin foam body has a density of 10 to 150 kg / m3, a thermal conductivity in a 10 DEG C environment of 0.0175 W / m.k or less, and a thermal conductivity in a 23 DEG C environment of 0.0185 W / m.k or less.

Description

technical field [0001] The present invention relates to a phenolic resin foam and a manufacturing method thereof. Background technique [0002] In recent years, high airtightness and high thermal insulation of houses have been demanded due to increased awareness of energy conservation and mandated next-generation energy conservation standards. With the improvement of the thermal insulation performance of such a house, the thickness of the required thermal insulation material is expected to increase, but there is a restriction on the pressure of the indoor living space and the space inside the wall, so it is necessary to change the design due to the increase in the thickness of the thermal insulation material. The problem. In addition, it is very difficult to update the heat insulating material while living in it because it is constructed into the wall, so it is necessary to maintain the heat insulating performance for a long time. [0003] As a heat insulating material for...
