High-performance plastic prepared by utilizing modified calcium carbonate and preparation method thereof

The invention discloses a high-performance plastic prepared by utilizing modified calcium carbonate and a preparation method thereof. The high-performance plastic comprises the following raw materials, in parts by weight: 55-80 parts of polyvinyl chloride, 25-40 parts of the modified calcium carbonate, 2-4 parts of nylon, 3-5 parts of chlorinated paraffin, 4-6 parts of borax, 1.2-2.3 parts of an antistatic agent, and 2.5-3.5 parts of mineral oil. The high-performance plastic is formed by performing full mixing on the above raw materials, and performing injection molding. According to the invention, after modification, a bulk accumulation density of the calcium carbonate employed by the invention remarkably becomes smaller, the modified calcium carbonate powder is fully dispersed, when the modified calcium carbonate powder is added to the plastic, an agglomeration phenomenon is small, dispersity is good, and the prepared plastic has high performance. 本发明公开了种利用改性碳酸钙制备的高性能塑料及其制备方法，所述高性能塑料，以重量份为单位，包括以下原料：聚氯乙烯55-8
