続成形方法である。 Conventionally, in the production of phenolic resin foam, when the stock solution is injected into a mold or casting device, the air that is mixed into the stock solution and the gas generated during foaming collect locally, forming large voids in the foam. It remained inside. A phenolic resin foam having such non-uniform voids has problems such as a decrease in mechanical strength and expansion of the molded product when heated. The purpose of the present invention is to provide a phenolic resin foam having a uniform foam layer, and the gist thereof is to provide a liquid-tight and breathable porous polymer layered with a breathable sheet. A stock solution of a foamable resin consisting of a resol-type phenolic resin, a blowing agent, and an acidic curing agent is cast onto a support a made of a sheet, and a support b having the same structure as the support a is placed parallel to the support a. The polymer sheet is layered on top of the foamable resin stock solution so that it is in contact with the foaming resin stock solution, and the supports a and b and the foamable resin stock solution are placed on top of the foamable resin stock solution so that the breathable sheet is in contact with the mold attachment. is continuously moved across the molding device to carry out foaming and curing in the molding device, and the foaming gas and water vapor are transferred to the supports a,
A phenolic resin characterized by passing through the holes in the polymer sheet of b, passing through the breathable sheet and discharging to the outside, and then separating the breathable sheets constituting supports a and b. This is a continuous foam molding method.

ため親水処理を施しておくのが望ましい。 The support a is composed of a liquid-tight and air permeable porous polymer sheet 1 overlaid with an air permeable sheet 2. The sheet 2 may be any material as long as it allows gas and water vapor generated during foaming and curing to pass therethrough, and specific examples thereof include woven fabrics, nonwoven fabrics, or knitted fabrics made of synthetic fibers or natural fibers, and even cardboard. The polymer sheet 1 is used to prevent wear and tear of foam molded products, improve handling properties, and improve mold release properties, and is a leak-proof and breathable porous polymer sheet. Examples include porous sheets or films made of polyolefins such as polyethylene and polypropylene, polyesters, polyamides, polyfluorides, and the like. The size and number of holes provided in the sheet or film may be within the range that provides liquid-tightness and breathability as described above, for example, holes with a diameter of 100μ or less. Such properties can be imparted by providing one to more than one per cm 2 . Furthermore, it is desirable that these sheets or films be subjected to hydrophilic treatment in order to improve ventilation of water vapor generated during production of the resol type phenolic resin foam.

As the blowing agent used at this time, there can be used blowing agents that can be used in ordinary phenolic resin foams, such as alkali metal carbonates, alkaline earth metal carbonates, lower paraffins, alcohols, ethers, and chlorofluorinated hydrocarbons. Examples of acidic curing agents include inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, pyrophosphoric acid, and polyphosphoric acid, benzenesulfonic acid, toluenesulfonic acid, metacresolsulfonic acid, resorcinolsulfonic acid, butylsulfonic acid, Organic acids such as propylsulfonic acid or mixed acids thereof can be used. The amount of blowing agent and acid curing agent used varies depending on the type, but the amount of blowing agent used is generally 3 to 30 parts by weight per 100 parts by weight of resol type phenolic resin.
The amount of the acidic curing agent is approximately 3 to 30 parts by weight. The resol type phenolic resin, its blowing agent, and the acidic curing agent are kneaded and uniformly dispersed in the mixing agitator 5 as described above, but two or more of them must be premixed before being supplied to the mixing agitator 5. You can stay there. In addition, flame retardants, fillers, foam stabilizers, etc. may be mixed into the foamable resin stock solution 3 as necessary.
These may also be supplied directly to the mixing agitator 5, or may be premixed and supplied.

イドは発生せずに均一な発泡層が得られる。 The foamable resin stock solution 3 cast onto the supports a and b and the support a is continuously passed through the molding device 6 so that the sheet 2 located on the outside is in contact with the molding device 6. The material is moved horizontally, and foaming and curing reactions are performed in the molding device to form the product. The foaming and curing reaction within this molding device involves a curing reaction between the resol type phenolic resin and the acidic curing agent.
The reaction heat generated at this time causes the foaming agent to volatilize, resulting in foaming. The resol type phenolic resin in which foaming and curing reactions are progressing is supported by supports a and b.
A skin layer is formed in close contact with the polymer sheet 1 constituting the supports a and b. Further, the foaming gas or water vapor passes through the polymer sheet 1 as shown in FIG. 2, travels through the breathable sheet 2, and is emitted to the outside.
If there is no breathable sheet 2, if a large amount of gas or water vapor is generated, the gas or water vapor that has passed through the polymer sheet 1 will tend to stay between it and the imprinting device 6. By overlaying the polymer sheet 1, gas and water vapor that have passed through the polymer sheet 1 are discharged to the outside through the breathable sheet 2. Therefore, even when a large amount of gas or water vapor is generated, a uniform foamed layer can be obtained without generating uneven voids due to accumulation of gas or water vapor.
