Mg-Al-based hydrotalcite-type particles, chlorine-containing resin composition and process for producing the particles |
摘要 |
<p>A resin composition suitable for covering an electric wire of the present invention, has a heat stability of not less than 240 minutes and a volume resistivity of 5.0 x 10<13> to 1.0 x 10<16> OMEGA .cm when measured according to JIS K6723, and comprises: (i) 100 parts by weight of a chlorine-containing resin, and (ii) 1.5 to 10 parts by weight of Mg-Al-based hydrotalcite-type particles having a composition represented by the formula: ÄMgxCayÜ.Alz.(OH)2.A<n-> p.mH2O wherein 0.2≤z/(x+z)≤0.6, 0.01≤y/(x+z)≤0.20, x+y+z=1, p=(2(x+y-1)+3z)/n, A is a-valent anion and m is more than 0 and not more than 0.75; having a plate surface diameter of 0.1 to 1.0 mu m and a thickness of 0.02 to 0.08 mu m; containing calcium at a molar ratio of Ca to the sum of Mg and Al of 0.01:1 to 0.20:1; and having a heat-resisting time of not less than 4 hours.</p> |
