The invention belongs to the technical field of synthetic resin and discloses a synthesis method of low-ash content polypropylene wire drawing material special-purpose resin. The synthesis method comprises that in the presence of a main catalyst and a cocatalyst, under the action of less or no use of external electron donors, propylene undergoes a polymerization reaction in a two-stage circular pipe reactor to produce a polypropylene resin base, and the low-ash content polypropylene resin product is prepared from the polypropylene resin base and an anti-oxidant. The main catalyst is prepared from HA-DQ and grease. The synthetic polypropylene wire drawing material special-purpose resin has ash content less than 0.01% so that special-purpose material mechanical properties and processing stability are improved.
