Modified environment-friendly polyolefin material and preparation method thereof

Abstract

The invention discloses a modified environment-friendly polyolefin material which comprises components with the following weight percentages: 40 percent to 70 percent of vegetable fiber, 20 percent to 50 percent of polyolefin resin, 3 percent to 8 percent of coupling agent, 3 percent to 10 percent of nano calcium carbonate, 3 percent to 5 percent of polypropylene oxide wax and 0.3 percent to 0.5 percent of antioxidant. The preparation method comprises the following steps of: preparing materials, mixing the materials at high speed, granulating and drying for later use. The polyolefin material can not only be biochemically degraded in nature, but also can be chemically degraded by chemical fertilizers, is in accord with the general orientation of environmental protection, fully meets the requirements of European ROHS, reaches the toy safety standard of EN71 / ASTM 963, contains no heavy metal, toxic elements or chemical substances damaging the ozone layer, and has the advantages of ultraviolet (UV) radiation resistance, mechanical performance against thermal and cold shocks and excellent pigmenting property.

Description

technical field [0001] The invention relates to a modified environment-friendly polyolefin material and a manufacturing method thereof. Background technique [0002] Existing products made of polypropylene resin or polyethylene resin are all injection molded with pure polypropylene resin or polyethylene resin. , The mechanical properties and degradability of resisting cold and heat shock are not very good, especially as people pay more and more attention to environmental protection, the requirements for the degradation performance of plastic products are getting higher and higher. Therefore, the traditional polypropylene resin or polyethylene resin products are increasingly subject to market and government restrictions. Although there are some degradable polypropylene resin or polyethylene resin products at present, they have not been widely promoted and applied because their degradability and other performances are not very satisfactory.

Problems solved by technology

[0002] Existing products made of polypropylene resin or polyethylene resin are all injection molded with pure polypropylene resin or polyethylene resin. , The mechanical properties and degradability of resisting cold and heat shock are not very good, especially as people pay more and more attention to environmental protection, the requirements for the degradation performance of plastic products are getting higher and higher. Therefore, the traditional polypropylene resin or products made of polyethylene resin are increasingly subject to market and government restrictions

Although some degradable polypropylene resin or polyethylene resin products have appeared at present, they have not been widely promoted and applied due to their unsatisfactory degradability and other properties.
