| 摘要 |
The present invention relates to a filler for inhibiting foaming caused due to CO2, which comprises hydrotalcite compound particles and calcium hydroxide particles and/or magnesium hydroxide particles, the use of the filler in a synthetic resin, and a shaped article formed therefrom, more particularly to a filler for inhibiting foaming, which is obtained by incorporating, into hydrotalcite compound particles represented by the following chemical structural formula (1): [(Mg2+)y(M12+)(1-y)]1-xM3+x(OH)2CO32−.mH2O  (Formula 1) (wherein M12+ represents a bivalent metal, M3+ represents at least one trivalent metal, and x, y, and m represent valences satisfying the relationships: 0<x<0.5, 0≦̸m<2, and 0<y≦̸1), calcium hydroxide particles and/or magnesium hydroxide particles so that the (calcium hydroxide particles and/or magnesium hydroxide particles):(hydrotalcite compound particles) ratio becomes 2:8 to 9:1, a resin composition having the filler incorporated thereinto and causing no foaming problem, and a shaped article formed therefrom. |
