The invention discloses a resistant non-migrating polyvinylchloride composite used for wires and cables, which comprises the following components according to a weight ratio: 100 proportion of polyvinyl chloride resin, 35-90 proportion of calcium carbonate, 40-95 proportion of plasticizer, 5-7 proportion of stabilizer, 0.6-1 proportion of slip agent, and 2-4 proportion of flame retardant. When being prepared, the polyvinyl chloride resin, the stabilizer, the plasticizer, the flame retardant, and the slip agent are according to a ratio added in a high-speed mixing roll to be stirred at a speedof 800 revolutions per minute for 3 minutes, then high-speed mixing is carried out when the calcium carbonate is added in, and finally granulation is carried out in a double stair granulator under a temperature of 140-165 DEG C. The composite of the invention has resistant non-migrating property, produces no migrating influence when being contacted with ABS or PS under a certain condition, and can be used for producing environmental protection wires and cables.
