The invention discloses an anti-cracking ABS material and a preparation method of a product thereof. The method comprises the following steps: firstly, carrying out emulsion polymerization on butadiene to obtain polybutadiene latex, then carrying out graft polymerization on the polybutadiene latex, styrene and acrylonitrile to obtain a rubber graft copolymer, and finally, carrying out mechanical blending and melt granulation on the rubber graft copolymer, SAN resin and an antioxidant to obtain the ABS resin. According to the ABS material prepared by the method disclosed by the invention, the particle size of the polybutadiene latex can reach 500 nm or above, so that the ABS material is high in toughness, the impact strength reaches 350 J/m or above, and the low-temperature resistance is enhanced. A product prepared from the ABS resin is subjected to annealing treatment, so that the crack resistance of the product is further improved. 本发明公开了一种防开裂ABS材料及其制品的制备方法。该方法首先将丁二烯进行乳液聚合，得到聚丁二烯胶乳，然后将聚丁二烯胶乳、苯乙烯及丙烯腈进行接枝聚合，得
