Abstract

A halogen-free flame-retardant polypropylene alloy material belongs to the technical field of polymer materials, and comprises the following components by weight: 69-78 parts of polypropylene resin, 15-21 parts of polymide resin, 5-9 parts of compatibilizer, 18-27 parts of flame retardant, 0.4-0.9 part of antioxygen, 11-18 parts of glass fiber, 0.6-1.2 parts of processing agents and 1.8-2.7 parts of carbon black. Tests prove that the prepared halogen-free flame-retardant polypropylene alloy material has the following properties: the flexural strength is greater than 80-94 MPa, the notch impact strength is greater than 16-18 kj / m2, the thermal deformation temperature is between 150 DEG C and 170 DEG C, and the flammability is V-0 (UL_94-1,6 mm).

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a halogen-free flame-retardant polypropylene alloy material. Background technique [0002] Polypropylene resin has excellent mechanical properties and is widely used in household appliances, office, packaging and other supplies. However, polypropylene has strong crystallinity, brittleness, and is not impact-resistant. Polyamide resin has the characteristics of wear resistance, heat resistance, high strength and impact resistance. Therefore, combining polypropylene with polyamide can further improve the heat resistance, wear resistance and impact resistance of polypropylene, thereby expanding the application range of polypropylene . The technical solution to be introduced below is produced under this background. Contents of the invention [0003] The task of the present invention is to provide a halogen-free flame-retardant polypropylene alloy material wi...
