Abstract: Disclosed are a polypropylene composite material capable of blasting at a low temperature, and a preparation method therefor and application thereof. The polypropylene composite material comprises the following components in parts by weight: 35-75 parts of special polypropylene A, 3-10 parts of special polypropylene B, 15-30 parts of a filler, 2-10 parts of a special toughening agent, 15-25 parts of a toughening agent, 0.1-0.3 part of a lubricant, 0.1-0.3 part of a photostabilizer, and 0.2-0.6 part of an antioxidant, wherein the special toughening agent comprises ultrahigh molecular weight polyethylene and a metallocene ethylene-propylene copolymer. The polypropylene composite material that is capable of blasting at a low temperature and has good rigidity is prepared by using the special polypropylene A, the special polypropylene B, and the special toughening agent in combination with the normal filler and the normal toughening agent, and the polypropylene composite material has a wide application prospect.

Abstract: Disclosed is a low-odor combustion-delaying polyolefin composition, which includes the following components by weight percentage: 56% to 99.7% of polyolefin; 0.3% to 2% of an ethoxyamide polymer; 0% to 2% of a delay combustion synergist; and 0% to 40% of a filler. Disclosed is also a use of the ethoxyamide polymer as a delay combustion agent in the polyolefin composition.
