Abstract
The invention discloses a polypropylene modified halogen-free flame retardant composite material and a preparation method thereof. The polypropylene modified halogen-free flame retardant composite material comprises the following components in part by weight: 50-75 parts of polypropylene, 10-40 parts of nucleating agents, 5-20 parts of flame retardant, 2-12 parts of compatilizer, 0.2-1 part of antioxidant and 0.1-1 part of lubricant. The polypropylene modified halogen-free flame retardant composite material has the beneficial effects that the nucleating agents Mg(OH)2 and ethylene-octylene copolymer are added, so that the crystallization temperature of polypropylene in the mixture is increased due to the heterogeneous nucleation effect of the two nucleating agents; by adding the flame retardant microencapsulated red phosphorus, the flame retardance of Mg(OH)2 is improved; and by adding the compatilizer PP-g-MAH (polypropylene-graft-maleic anhydride), the interfacial compatibility between polypropylene and Mg(OH)2 is improved, and the mechanical properties of polypropylene are enhanced.
