- the present invention relates to a foamable resin composition having a high expansion ratio and capable of obtaining a foam having uniform and independent cells.
- foams produced using a foamable resin composition are widely used, and such foamable resin compositions have an expansion ratio at the time of foaming.
- a thermal decomposition type chemical blowing agent is used.
- a foamable resin composition containing heat-expandable microcapsules is known as a resin composition having thermal foamability.
- a foamable resin composition containing thermally expandable microcapsules which has been conventionally used. It was necessary to include a thermally expandable microphone mouth capsule.
- an object of the present invention is to provide a foamable resin composition from which a foam having a high expansion ratio and having uniform and independent cells can be obtained.
- the present invention relates to a foamable resin composition
- a foamable resin composition comprising a heat-expandable micro force capsule and a resin composition.
- the heat-expandable microcapsules are foamable resin compositions in which the temperature at which thermal expansion starts is less than the curing start temperature of the resin composition + 1 ° C.
- the heat-expandable microcapsules preferably have a maximum thermal expansion temperature of less than the curing start temperature of the resin composition + 60 ° C.
- the resin composition is preferably a plastisol, and the plastisol preferably contains a vinyl chloride resin or an acrylic resin. Further, the resin composition preferably contains a thermosetting resin.
- the resin composition since the expansion of the heat-expandable microphones is started after the resin composition is cured, it has been found that the expansion of the heat-expandable microcapsules is suppressed by the already cured resin composition. . It has also been found that, after the resin composition has hardened, if the heat-expandable microcapsules further attempt to expand, the pressure will cause deterioration and cracking of the foam.
- the present inventors have further studied diligently, and found that the use of an expandable resin composition in which the curing properties of the resin composition and the thermal expansion properties of the heat-expandable microcapsules have a certain relationship has resulted in high foaming. It has been found that a foam having a magnification and free from cracks or the like can be obtained. That is, if the resin composition and the thermally expandable microcapsule are combined so as to satisfy the following conditions, a foamable resin composition capable of producing a foam having a high expansion ratio and free from cracks or the like can be produced. Things are obtained.
- the foamable resin composition of the present invention is a foamable resin composition comprising a heat-expandable microcapsule and a resin composition, wherein the heat-expandable microcapsule opens a thermal expansion.
- a temperature at which the curing is started is lower than a curing initiation temperature of the resin composition + 1 ° C.
- the foamable resin composition of the present invention comprises a heat-expandable microcapsule and a resin composition.
- the thermally expandable microcapsules are not particularly limited, and include, for example, microcapsules in which a volatile expanding agent is encapsulated in a thermoplastic resin.
- the resin composition is not particularly limited, and examples thereof include a plastisol and a curable resin composition containing a thermosetting resin such as an epoxy resin and a melamine resin.
- the above plastisol is not particularly limited, and examples thereof include vinyl chloride plastisol and acrylic plastisol.
- the plastisol refers to a sol-like mixture in which a plasticizer and the like are mixed in a thermoplastic resin. Plastisol can form a coating film by gelation due to impregnation with a plasticizer or the like.
- the temperature at which thermal expansion starts is less than the curing start temperature of the resin composition + 10 ° C.
- the curing start temperature of the resin composition is equal to or higher than + 10 ° C.
- the thermally expandable microcapsules start to expand after the resin composition is cured.
- the expansion of the expandable microcapsule is suppressed or the foaming is started after the resin thread and the cured product are cured, the produced foam may deteriorate and crack.
- the maximum thermal expansion temperature of the thermally expandable microcapsules is preferably lower than the curing start temperature of the resin composition + 60 ° C.
- the curing start temperature of the resin composition means a temperature at which the melt viscosity starts to increase when the resin composition is a plastisol, and a temperature at which curing is started when the resin composition is a curable resin composition. means.
- the curing start temperature is determined by the components contained in the resin composition.
- the plastisol is a butyl plastisol chloride.
- the temperature is 120 to 130 ° C.
- the curing start temperature of the plastisol can be measured, for example, by obtaining an elasticization point from the tensile strength of the sample film and using a thermal bench method at each temperature.
- the curing start temperature of the curable resin composition can be measured, for example, from the temperature at which the viscoelastic spectrum elongates and the modulus of elasticity rises.
- thermo expansion start temperature means the temperature at which the thermally expandable microcapsules substantially start thermal expansion, and the maximum of the thermally expandable microforce capsule.
- the thermal expansion temperature refers to the temperature at which the heat-expandable micro-force cell does not expand any more, but rather begins to contract, even when heated.
- thermal expansion onset temperature and the maximum thermal expansion temperature are measured, for example, by using TA Instruments' “Thermo-mechanical analysis device (TMA)”, 250 g of the thermally expandable microcapsules are 7 mm in diameter and 7 mm in depth. Put in a 1 mm cylindrical aluminum container, heat from 80 ° C to 220 ° C at a rate of 5 ° CZ from the top with 0.1 N force applied from above, and pressurize This can be done by measuring the amount of displacement of the terminal in the vertical direction. In this case, the temperature at which the displacement starts to be observed is defined as the thermal expansion start temperature (T s), and the temperature indicating the maximum displacement is defined as the maximum thermal expansion temperature (T max).
- T s thermal expansion start temperature
- T max maximum thermal expansion temperature
- the caloric content of the heat-expandable micro force cell is preferably 0.01 to 10 parts by weight based on 100 parts by weight of the resin composition. . If the amount is less than 0.01 part by weight, the effect of reducing the weight of the obtained foam may be small. If the amount exceeds 10 parts by weight, the strength of the obtained foam may be poor.
