Definitions
- the present invention relates to a method for producing a rigid polyurethane foam used as a heat insulating material. More specifically, the present invention relates to a rigid polyurethane foam that maintains low thermal conductivity for a long period of time and has good adhesion in a low temperature environment.
- Rigid polyurethane foam for foam molding of a mixture containing polyisocyanate, polyol, foaming agent, and auxiliary agents such as a catalyst and a flame retardant is widely used as a material excellent in molding processability.
- Rigid polyurethane foam has the advantage of increasing strength as a composite structural material, unlike self-adhesive heat insulating materials such as foamed polystyrene, by self-adhesion with face materials during foaming.
- rigid polyurethane foam can be molded by various foaming methods such as pouring and spraying, and can be foamed on site without requiring large-scale equipment.
- hydrocarbon foaming agents are dangerous materials under the Fire Service Act and require a large amount of capital investment, so they are difficult to use except for mass production lines such as refrigerators.
- fluorinated hydrocarbons have a greenhouse effect and have an impact on global warming, and may become unusable in the future. Therefore, it is thought that diacid-carbon foamed rigid polyurethane foam will be widely used in the future.
- the heat conductivity of gas is higher than that of chlorofluorocarbon, the heat insulation of rigid polyurethane foam is generally conventional. There is a problem that it is considerably worse than the ones.
- the heat insulation thickness cannot be increased depending on the product shape, installation location, etc., it may not be suitable as a heat insulation material, especially in the refrigeration field.
- carbon dioxide is known to be more permeable than air and has a very high permeability to polyurethane resin membranes compared to chlorofluorocarbon, which is a blowing agent with a large molecular weight. It is easy to come out to the outside gradually. For this reason, not only in the case of 100% water foaming, but also in formulations with a high proportion of water in the formulation, there is a problem that the initial thermal conductivity of rigid polyurethane foam cannot be maintained for a long time, which is a supercritical state.
- Patent Document 1 whose title is “manufacturing method of rigid polyurethane foam”.
- a rigid polyurethane foam used as a heat insulating material for buildings or the like by a spray method, or a metal sizing material manufactured by a continuous laminate manufacturing method For applications such as shutters, for example, a Mannheim condensate or a polyether polyol obtained by adding alkylene oxide to ethylenediamine or the like is often used as a polyol component.
- rigid polyurethane used as a heat insulating material for refrigeration and refrigeration equipment by injection molding for example, a polyol or a polyether polyol obtained by adding alkylene oxide to toluene diamine or the like is often used as a polyol component.
- a large amount of carbon dioxide is used as a foaming agent, the rigid polyurethane foam obtained from these polyether polyols is particularly deteriorated after the passage of time in thermal conductivity.
- Patents relating to deterioration of thermal conductivity after elapse of time include a patent whose title is “Production method of polyurethane foam having closed cells” (Patent Document 2), “Polyurethane foam with improved heat insulation performance” (Patent Document 3), “Patent Document 3”, “Patent Document 3”, etc. Patents that have “Hard Polyurethane Foam and Thermal Insulator” (Patent Document 4), etc. There is. Patents relating to polyols for improving thermal conductivity include a patent (Patent Document 5) whose title is “Method for producing rigid polyurethane foam”.
- Patent Document 6 a patent whose title is “manufacturing method of spray-type rigid polyurethane foam”.
- the rigid polyurethane foam foamed with carbon dioxide has a higher rate of dimensional change and lower dimensional stability at a low density level than the foam foamed with conventional HCFC-141b. ing. If such a foam is left at room temperature, it will gradually shrink over a long period of time, which may eventually lead to abnormal product appearance. This may be due to the fact that the carbon dioxide in the foam bubbles is likely to be released to the outside through the polyurethane resin film. Therefore, there is a demand for improved dimensional stability, for example, by developing rigid polyurethane foams that do not allow carbon dioxide to permeate.
- Patents relating to the dimensional stability of 100% water-foamed rigid polyurethane foam include the patent whose title is “Method for producing rigid polyurethane foam” (Patent Document 7) and “Method for producing rigid polyurethane foam”. (Patent Document 8).
- the choice of polyol is important because it has a significant effect on the performance of these foams.
- a polyol obtained by adding alkylene oxide to ethylenediamine or the like, or a polyol obtained by adding alkylene oxide to sugar or toluenediamine or the like a large amount of water is used during the formulation.
- rigid polyurethane foam the necessary performance required for practical use such as low flyability, low adhesion and excellent dimensional stability in a low temperature environment with low thermal conductivity and little deterioration over time. It is difficult to obtain a satisfactory rigid polyurethane foam.
- the present invention provides a method for solving these problems.

- the object of the present invention is to provide a hard material suitable for water or carbon dioxide foaming, which has low fly conductivity in a low temperature environment with little deterioration in thermal conductivity after time, has low adhesiveness, and has excellent dimensional stability. It is to provide a polyurethane foam.
- the inventors of the present invention pay attention to the fact that the foam power of the polyol force obtained by using the conventional mechanical strength is fine, the foam bubbles of the foam are fine, the thermal conductivity is low, and the dimensional stability is good. It was.
- various aryl polyols for 100% water foaming by changing the type, mass ratio, and hydroxyl group value of alkylene oxide. As a result, it was found that the deterioration of the thermal conductivity after the passage of time was specifically reduced within a certain range.
- aromatic monoamine polyols which are aromatic monoamine compounds similar in structure to arrin, starting with acidin, xylidine, toluidine, nitro-phosphorus, etc. and having alkylene oxide added thereto Therefore, it was found that the result of the evaluation has almost the same effect.
- the first invention of the present invention is a method for producing a rigid polyurethane foam obtained by foam-molding a mixture containing a polyisocyanate, a polyol and a foaming agent, and as a part of the polyol component, Aromatic monoamine compounds with ethylene oxide and propylene A mass ratio of 50 to: LOO: 50 to 0, a total of 3 to 7 moles of addition polymerized, and a polyol having a hydroxyl value of 250 to 500 mg KOHZg was used. It is a manufacturing method of the hard polyurethane foam for heat insulating materials characterized by using 20-: L00 mass parts among mass parts.
- the aromatic monoamine compound preferably has a molecular weight of 90 to 170.
- the aromatic monoamine compound may be selected from the group consisting of a-line, a-cidine, aminoacetamide, aminophenol, amino-benzoic acid ethyl ester, isopropoxy-line, xylidine, cresidine, toluidine, phenetidine, ⁇ -phenol.
- -Luethylamine, 13-phenylamine (phenethylamine), benzylamine, 2-tro-aline, and their isomers are selected from any one group or any combination.
- the second invention of the present invention is a method for producing a rigid polyurethane foam obtained by foam molding a mixture containing a polyisocyanate, a polyol and a foaming agent, wherein at least part of the polyol component.
- the aromatic diol compound preferably has a molecular weight of 90 to 170.
- aromatic diol compound is selected from catechol, dihydroxynaphthalene, resorcin, and the group power of these isomers, either one or any combination! /.
- the foaming agent is mainly diacid-carbon.
- the present invention is suitable for water or dioxycarbon foaming with low fly conductivity in a low temperature environment with little deterioration of thermal conductivity after time, excellent fly adhesion and excellent dimensional stability.
- a rigid polyurethane foam can be provided.
- heat conduction of rigid polyurethane foam includes heat conduction of gas in bubbles, heat conduction by radiation, heat conduction of a solid layer passing through a resin, and heat conduction by convection. It is said that the reason why carbon dioxide rigid polyurethane foam has high thermal conductivity and poor thermal insulation is that the thermal conductivity of carbon dioxide is higher than that of Freon gas. 10 blowing agents
- the heat conduction of the gas can be made constant by using 0% water and the number of moles of carbon dioxide and carbon dioxide in the formulation being constant, and if the bubble diameter of the rigid polyurethane foam is made constant, the heat conduction by radiation is almost the same. Can be constant. Convection does not occur when the bubble diameter is 0.4 mm or less, so heat conduction by convection is negligible.
- the bubble diameter is kept constant, only the polyol is changed, a 100% water-foamed rigid polyurethane foam is prepared, and the initial thermal conductivity is measured, the correlation between the thermal conductivity of the polyol and the solid layer is obtained. It is thought that. However, as a result of such measurement, the initial value of thermal conductivity of the 100% water-foamed rigid polyurethane foam showed almost no difference in general polyols.
- the number of moles of carbon dioxide in the formulation was fixed, the polyol was fixed, and the thermal conductivity was measured by changing the bubble diameter. Theoretically, the heat conduction of radiation is considered to be smaller as the bubble diameter becomes smaller.
- the inventors of the present invention can improve the thermal conductivity by increasing the diacid-carbon barrier properties of the resin constituting the rigid polyurethane foam so that the diacid-carbon can be contained in the bubbles. We focused on the point that the change after the elapse of time can be minimized. If the initial value of thermal conductivity is within the allowable limits for carbon dioxide foamed rigid polyurethane foam, and the change in thermal conductivity after the passage of time can be made equivalent to that of HCFC-141b, the design will change significantly. Unbelievable It may be applicable to the freezing field. Moreover, if this is possible, an improvement in dimensional stability can be expected.
- Fig. 1 shows the core foam cut to 16mm, the foam with the skin layer, and the foam with the steel plate surface, using the same formulation of 100% water foaming (Toho Chemical Industry Co., Ltd., using the undiluted solution Hicell M-595). The graph of change after time progress of thermal conductivity is shown.
- a general fluorocarbon foamed rigid polyurethane foam manufactured by Toho Chemical Industry Co., Ltd., using the stock solution name High Cell M-505 are also shown in FIG.
- the thermal conductivity of the core foam reached a constant value after 60 to 90 days after the initial value force continued to deteriorate, reaching equilibrium. Its value is approximately 0.032 to 0.033 W / mK (0.028 kcal Zmh ° C), and the carbon dioxide in the bubbles permeates through the resin film constituting the bubbles with time, and is replaced with air. The result is considered.
- foam with a skin layer takes approximately 150 days to reach 0.033WZmK, and foam with iron plate face has thermal conductivity after 150 days or more, as with the HCFC-141b foaming formula. It was found that the deterioration continued and the deterioration rate was slow and time was required for evaluation.
- the deterioration of the thermal conductivity after time is evaluated based on the value after 60 days of the core foam cut to 16 mm, and the ratio between the measured value after 14 days and 28 days after that and the initial value is used as a measure of the deterioration rate. It was decided to evaluate as.
- the goal is that the thermal conductivity of the core foam cut to 16 mm after 60 days is comparable to 0.026 WZmK after 60 days of the HCFC-141b foaming formula, and well below 0.033 WZmK of the 100% water foaming formula. It was.
- the polyol used is an aromatic monoamine compound or an aromatic diol compound as a starting material. It is characterized by being an aromatic polyol.
- the first polyol used in the present invention is an aromatic monoamine polyol starting from an aromatic monoamine compound, and has two active hydrogen atoms.
- the addition of a predetermined amount of alkylene oxide to an aromatic monoamine compound having a molecular weight of 90 to 170, particularly 93 to 166, has a low thermal conductivity degradation over time. Is preferable.
- the number of active hydrogens is large, it is necessary to add a large number of moles of alkylene oxide to obtain a suitable hydroxyl value as a polyol, and it is considered that the diacid-carbon barrier property is impaired.
- the molecular weight is large, the molecular weight ratio of the aromatic ring in the molecule is small, and similarly, the diacid-carbon barrier property is impaired.
- the second polyol used in the present invention is an aromatic polyol starting from an aromatic diol compound, and the number of active hydrogens is preferably two. Further, a force obtained by adding a predetermined amount of alkylene oxide to an aromatic diol compound having a molecular weight of 90 to 170, particularly 110 to 161, is preferable in that the thermal conductivity is less deteriorated over time.
- the number of active hydrogens is large, it is necessary to add a large number of moles of alkylene oxide in order to obtain a suitable hydroxyl value as a polyol, and it is considered that the carbon dioxide barrier property is impaired. Also, if the molecular weight is large, the aromatic ring molecules in the molecule It is considered that the amount ratio is reduced, and the carbon dioxide barrier property is similarly impaired.
- the mass ratio of ethylene oxide to propylene oxide is 50 to 100: 50 to 0, preferably 70 to: LOO: 30 to 0, more preferably 80 to: LOO: 20 to 0, particularly preferably 90 to: L00: 10 to 0, the total number of moles is 3 to 7 moles, preferably 4 to 7 moles, and the hydroxyl value is 230 to 500 mgKOHZg, preferably 300 to 450 mgKOH It was found that the aromatic polyol with / g was the best.
- ethylene oxide is most preferable, and 100% ethylene oxide-added polyol has the least deterioration after the lapse of time of thermal conductivity.
- the mass ratio of propylene oxide is increased, the foam fluidity is improved, but the thermal conductivity is somewhat deteriorated after a lapse of time, and the adhesiveness in a low temperature environment is deteriorated.
- the reason why the deterioration of thermal conductivity after the passage of time is small and the deterioration rate is slow is that the ratio of ethylene oxide is particularly high compared to general polyols, and the number of moles of added alkylene oxide is further increased. This is because the molecular weight ratio of non-aromatic molecules is small and the molecular weight ratio of the aromatic part is high, especially because it satisfies the condition that the obtained rigid polyurethane foam has extremely high diacid-carbon nourishing properties. It can be considered.
- 100% water-foamed rigid polyurethane foam which also has a polyether polyol power obtained by adding an alkylene oxide to Mannheim condensate, ethylene diamine, sucrose, toluene diamine, etc., has an aromatic part relative to the molecular weight.
- the thermal conductivity is low due to the low molecular weight of carbon dioxide or the number of moles of adducted alkylene oxide. It is considered that the deterioration of the rate after the passage of time is large. However, there was a difference in the rate of deterioration of thermal conductivity depending on the type of polyol, and some were relatively good after 14 to 28 days, but all reached equilibrium after 60 days.
- the molecular weight ratio of the aromatic moiety (generally referred to as aromatic concentration or aromaticity) is represented by the following formula (1).
- the average molecular weight Mp of the polyol in (Formula 1) is represented by the following formula (2).
- the thermal conductivity of the rigid polyurethane foam in which the polyol used has a high aromatic concentration undergoes little deterioration after the passage of time, other performances may be poor.
- the thermal conductivity is less deteriorated after the passage of time. Is poor and practical.
- the polyol strength of the present invention The reason why the obtained rigid polyurethane foam has a small deterioration in thermal conductivity after a lapse of time is considered to be due to its high diacid-carbon barrier property. Carbon dioxide does not have to be generated by the reaction force of water and polyisocyanate, and the same effect can be obtained even in supercritical, subcritical, liquid carbon dioxide, or compressed carbon dioxide. I can expect.
- water is preferably 1 to 8 parts by weight with respect to 100 parts by weight of polyol. Is preferably 1 to 8 parts by mass per 100 parts by mass of polyol.
- hydrocarbon or fluorinated hydrocarbon blowing agent is 5 to 30 parts by mass with respect to 100 parts by mass of polyol in the formulation. It is considered sufficient to use it.
- the polyols of the present invention those having a high mass ratio of ethylene oxide are produced by a continuous laminate production method or the like because they have high catalytic activity, high strength, and good dimensional stability. It is suitable for applications such as metal sizing materials, shutters, etc., and even if there is no face material such as metal when the foam is exposed, the deterioration of the thermal conductivity after the passage of time is small, and the viscosity is extremely low. Because of its good adhesiveness in low temperature environments, it is considered to be suitable for the spray method. In addition, the force to increase the mass ratio of propylene oxide as appropriate, Alternatively, the foam fluidity can be improved by appropriately using other polyols in combination, and a polyol suitable for injection molding can be obtained.
