Abstract

The invention relates to the technical field of polyethylene material production, and discloses a formula for enhancing toughness and strength of a calcium carbonate high-filled PP polyethylene material. The formula comprises the following components,by weight, 50-55 parts of ethylene, 5-10 parts of a polyethylene catalyst, 10-15 parts of propylene, 1-2 parts of a polypropylene catalyst and 1-2 parts of calcium carbonate. According to the invention, aJL-G02 type modifier, benzenediol and the hexamethylenetetramine modified calcium carbonate are used for filling polyethylene, so that the polyethylene material filled and produced by the modified calcium carbonate is different from the polyethylene material filled and produced by the common modifier modified calcium carbonate; and the tensile property, the elongation at break, the Young modulus and the notch impact strength of the polyethylene material are greatly improved, and the polyethylene material has extremely high toughness and extremely high strength.

Description

technical field [0001] The invention relates to the technical field of polyethylene material production, in particular to a formula for enhancing toughness and strength of calcium carbonate highly filled PP polyethylene material. Background technique [0002] In the production of polyethylene materials, it is usually necessary to add calcium carbonate to the ethylene raw material to enhance the toughness and strength of polyethylene materials. [0003] A Chinese patent discloses a calcium carbonate-filled modified linear low-density polyethylene film and its preparation method (authorized announcement number CN104530554). This patented technology uses a mixture of potassium perfluorobutane sulfonate and octyl phthalate to modify calcium carbonate , The toughness and strength of the polyethylene material produced have been improved to a certain extent, but this method of improving calcium carbonate is more conventional, and the toughness and strength of the polyethylene mater...
