Problems solved by technology

However, the high-efficiency utilization technology of calcium carbonate in my country and the world has developed slowly. For a long time, the calcium carbonate used in plastics is mainly filled with about 20%, which has not really improved the processability of plastics and improved the quality of plastic products. Stability and reduce the cost of plastic products

Abstract

The invention discloses a PPM environment-friendly material and a preparation method thereof. The PPM environment-friendly material comprises the following components in percentage by weight: 80%-85% of calcium carbonate, 15%-20% of carrier resin, 0.5%-10% of a dispersing agent, 0.5%-10% of a lubricating agent, 0.5%-10% of a coupling agent and 0.1%-3% of an antioxidant. The preparation method of the PPM environment-friendly material comprises the following steps: coating and modifying the calcium carbonate; banburying and mixing the modified calcium carbonate with the carrier resin, lubricating agent and antioxidant; carrying out extruding granulation and finishing air cooling, screening and packaging until finishing the whole preparation process. The PPM environment-friendly material has easily available preparation raw materials, low cost, high quality, mature process, convenience for popularization and obvious effects. The PPM environment-friendly material can be extensively applied to the fields of processing of plastic products, particularly to the industries of plastic packaging, agricultural plastics and plastic construction materials.

Description

technical field [0001] The invention relates to a PPM environment-friendly material and a preparation method thereof. Background technique [0002] China is one of the countries rich in limestone mineral resources in the world. In addition to Shanghai, Hong Kong, and Macau, it is distributed in all provinces, municipalities, and autonomous regions. According to the statistics of the Geological Center of the former National Building Materials Bureau, the distribution area of ​​limestone in the country reaches 438,000 Km2 (not including Tibet and Taiwan), accounting for about 1 / 20 of the country's land area. [0003] It has become a development trend of the plastics industry to use inorganic fillers such as calcium carbonate to replace some petroleum plastics, save petroleum resources and reduce material costs at the same time. Calcium carbonate can be widely used in rubber, paint, paper, plastic, ink and other fields. However, the high-efficiency utilization technology of ...
