Definitions
- the present invention relates to a phenol resin foam laminate and a method for producing the same.
- Phenolic resin foam laminates are widely used as building materials and general industrial materials because they have high heat insulation performance, flame retardancy, and heat resistance among foamed plastic heat insulation materials. If you want to ensure the airtight performance of the insulation layer in high-temperature environments that are particularly severe conditions for insulation materials such as roofs of buildings, install a sealing material separately between the insulation materials or between the insulation material and the frame. There was, and it took time and effort of construction. Moreover, finishing materials such as mortar and resin were laminated on the surface of a composite plate obtained by joining a phenolic resin foam laminate and another member or a phenol resin foam laminate laminated on the same plane without any gaps. In the heat insulating structure, there has been a problem that warpage occurs and cracks occur in the finished material due to the dimensional change of the phenolic resin foam laminate.
- Patent Document 1 proposes a method for manufacturing a phenolic resin foam laminate in which a plurality of primary foams are stacked in a hot air curing furnace via a spacer and post-cured at a predetermined temperature and wind speed.
- Patent Document 1 a phenol resin foam laminate having dimensional stability required after construction is not obtained.
- an object of the present invention is to provide a phenolic resin foam laminate having improved dimensional stability as compared with the prior art and a method for producing the same.
- the inventors want to ensure the airtight performance of the heat insulation layer provided with the phenol resin foam, if the dimensional change rate of the phenol resin foam laminate is extremely small, the heat insulation material is slightly compressed in the in-plane direction. It was found that by tightly fitting while applying airtightness, it is possible to secure the airtight performance after construction without separately installing a sealing material or the like. Furthermore, the present inventors have found that the following effects can be obtained by reducing the dimensional change rate of the phenol resin foam laminate. That is, it discovered that about the composite board obtained by joining a phenol resin foam laminated board and another member, the curvature which arises by the dimensional change of the member of the one side in a composite board can be prevented.
- the phenol resin foam It has been found that it is possible to prevent the finishing material from being destroyed due to the difference in dimensional change between the body laminates and the joints with other members.
- the present invention provides the following [1] to [6].

- FIG. 1 is a schematic view showing a phenolic resin foam laminate according to this embodiment.
- the phenol resin foam laminate 1 includes a face material 2 and a phenol resin foam 3, and the face material 2 includes a first face material 2 a and a first face material 2 a. 2 face materials 2b.
- the phenol resin foam 3 is a plate-like member sandwiched between the face materials 2a and 2b.
- the face materials 2a and 2b cover the principal surfaces (surfaces) facing each other of the phenol resin foam 3, and the principal surface of the phenol resin foam 3 and the principal surfaces of the face materials 2a and 2b are in contact with each other. .
- the phenolic resin foam 3 includes a phenolic resin, a curing catalyst for the resin, a foaming agent containing a hydrocarbon, a chlorinated aliphatic hydrocarbon, or a combination thereof, and a surfactant.
- the product is obtained by foaming and curing.
- the phenol resin can be obtained, for example, by polymerizing the above raw materials using phenols and aldehydes as raw materials and heating them with an alkali catalyst in a temperature range of 40 to 100 ° C. Moreover, you may add additives, such as urea, at the time of resole resin polymerization as needed. In the case of adding urea, it is preferable to mix urea that has been methylolated with an alkali catalyst in advance into the resole resin. Since the phenol resin after synthesis usually contains excess water, it is preferable that the phenol resin be dehydrated to a foamable amount of water.
- the moisture content in the phenolic resin is 1.0 wt% or more and 10.0 wt% or less, preferably 1.0 wt% or more and 7.0 wt% or less, more preferably 2.0 wt% or more and 5. wt% or less. It is 0 wt% or less, and particularly preferably 2.0 wt% or more and 4.5 wt% or less.
- it takes a great deal of energy and time during dehydration resulting in a significant decrease in productivity and improved dimensional stability. It becomes difficult to obtain a resin foam laminate sufficiently.
- the moisture content contained in the phenolic resin exceeds 10.0% by weight, the amount of moisture in the resulting foam increases, resulting in an increase in the amount of drying shrinkage in a high-temperature environment, resulting in dimensional stability. It becomes difficult to sufficiently obtain an improved phenolic resin foam laminate.
- the starting molar ratio of phenols to aldehydes in the phenolic resin is preferably from 1: 1 to 1: 4.5, more preferably from 1: 1.5 to 1: 2.5.
- the phenols preferably used in the synthesis of the phenol resin include phenol or a compound having a phenol skeleton.
- the compound having a phenol skeleton include resorcinol, catechol, o-, m- and p-cresol, xylenols, ethylphenols, p-tertbutylphenol and the like. Dinuclear phenols can also be used.
- aldehydes used in the production of phenol resin include formaldehyde (formalin) or aldehyde compounds other than formaldehyde.
- aldehyde compounds other than formaldehyde include glyoxal, acetaldehyde, chloral, furfural, benzaldehyde and the like.
- Urea, dicyandiamide, melamine or the like may be added to the aldehydes as an additive.
- "phenol resin" points out the thing after adding an additive.
- the viscosity of the phenol resin is 5000 mPa ⁇ s or more and 100000 mPa ⁇ s or less at 40 ° C.
- the viscosity at 40 ° C. of the phenol resin is preferably 7000 mPa ⁇ s or more and 50000 mPa ⁇ s or less, more preferably 10,000 mPa ⁇ s or more and 40000 mPa ⁇ s or less, from the viewpoint of securing the closed cell ratio and the production cost.
- the cell wall is broken because the viscosity of the resin is too low with respect to the foaming pressure generated by vaporizing the foaming agent, and the closed cell ratio is reduced.
- the viscosity of the phenol resin exceeds 100,000 mPa ⁇ s, the viscosity of the resin becomes too high with respect to the foaming pressure, so that a predetermined expansion ratio cannot be obtained and a predetermined space can be filled during foam molding. Therefore, it becomes difficult to sufficiently obtain a phenol resin foam laminate having improved dimensional stability, and the density of the phenol resin foam and the smoothness of the surface are impaired.
- Residual phenol contained in the phenolic resin is 1.0 wt% or more and 4.3 wt% or less, preferably 2.3 wt% or more, from the viewpoint of easy adjustment of the phenolic resin and securing foamability. It is 4.25% by weight or less, and more preferably 2.7% by weight or more and 4.2% by weight or less. If the residual phenol in the manufactured phenol resin foam exceeds 4.3% by weight, the resin portion of the phenol foam is softened due to the plasticizing effect, and the dimensional change is increased. If the residual phenol is less than 1.0% by weight, the reactivity of the phenol resin is lowered, and the expression of the strength of the phenol resin during foam molding is delayed, so that the closed cell ratio is lowered.
- the phenol resin may contain an additive.
- an additive for example, phthalic acid esters and glycols that are generally used as a plasticizer, ethylene glycol, diethylene glycol, and the like can be used. Moreover, you may use an aliphatic hydrocarbon, a high boiling point alicyclic hydrocarbon, or mixtures thereof.
- the content of the additive is preferably 0.5 parts by weight or more and 20 parts by weight or less with respect to 100 parts by weight of the phenol resin. When the content of the additive exceeds 20 parts by weight, the viscosity of the phenol resin is remarkably lowered, and there is a tendency to induce bubble breakage at the time of curing foaming, and the content of the additive is less than 0.5 parts by weight. And the meaning of containing an additive tends to fade.
