The invention discloses a modified resin composition, which includes the following components of, by weight, 35% to 95% of
polyamide, 4% to 15%
laser sensitive additives and 1% to 60% of other additives, and the added weight of the total content is 100%. The chemical general formula of the
laser sensitive additives is XY2O4, and the
laser sensitive additives are of isometric
crystal system with the
axial length a=b=c and the axial
angle alpha=beta=gamma=90 degrees; a tetrahedral atom is a
metal atom from an IIIA group, an IB group, an IIB group, a VIB group, a VIIB group and a VIII group of
periodic table of the elements, wherein the
metal atom includes one of
chromium,
manganese, iron,
cobalt,
nickel,
copper,
zinc,
palladium and aluminum, preferably one of
transition metal chromium,
manganese,
copper and
metal palladium; and an octahedral atom is a metal atom from an IIIA group, an IB group, an IIB group, a VIB group, a VIIB group and a VIII group of
periodic table of the elements, wherein the metal atom includes one of
chromium,
manganese, iron,
cobalt,
nickel,
copper,
zinc,
palladium and aluminum, preferably one of
transition metal chromium, manganese, copper and metal palladium. The modified resin composition has the advantages of being high in
processing temperature and small in space among metal wires.
