The invention provides a calcium carbonate grind-aiding modifier for plastic rubber. The modifier is prepared from the following raw materials in parts by weight at least: 3 to 10 parts of saturated fatty acid, 5 to 15 parts of polyethylene glycol oleate and 50 to 100 parts of water. According to the calcium carbonate grind-aiding modifier provided by the invention, the modifier can form a contactbarrier between inorganic matters so that the dispersion effect of the inorganic matters can be improved. Secondly, the mechanical property of a base material can be improved by the grind-aiding modifier provided by the invention, and the grind-aiding modifier can be used for dispersing calcium carbonate very well and a cross-linking point can be formed between the surface of the grind-aiding modifier and the base material, so that the mechanical property of the product is improved and the toughness and the impact strength of the plastic rubber also can be improved. 本发明提供种塑料橡胶用碳酸钙助磨改性剂，按照重量份计，所述改性剂的制备原料至少包含：饱和脂肪酸3-10
