    • The present invention relates to a polyolefin-based composite resin composition having a low coefficient of linear thermal expansion, wherein the composition comprises a) 40 to 80 weight % of crystalline ethylene-propylene copolymer, b) 5 to 40 weight % of ethylene-alpha-olefin copolymer, c) 5 to 30 weight % of calcium-metasilicate based wollastonite, and d) 5 to 30 weight % of inorganic reinforcing agent based on the total composition amount. The polyolefin-based composite resin composition having a low coefficient of linear thermal expansion not only has excellent mechanical rigidity, impact resistance, heat resistance, injection moldability, product flatness, and dimensional stability, but also has a low shrinkage, a low coefficient of linear thermal expansion, and a low heat sag. Therefore, it can be used for the manufacture of automobile exterior components.
    • 本发明涉及一种具有低线性热膨胀系数的聚烯烃基复合树脂组合物,其中组合物包含a)40至80重量%的结晶乙烯 - 丙烯共聚物,b)5-40重量%的乙烯-α α-烯烃共聚物,c)5〜30重量%的硅酸钙硅灰石,d)5〜30重量%的无机增强剂。 具有低线性热膨胀系数的聚烯烃类复合树脂组合物不仅具有优异的机械刚性,耐冲击性,耐热性,注塑成型性,产品平面度和尺寸稳定性,而且收缩率低,线性系数低 热膨胀和低热下垂。 因此,可以用于汽车外部件的制造。
