Abstract

The invention discloses a halogen-free and flame-retardant long glass fiber reinforced TPEE composite material and a preparation method thereof. TPEE is adopted as matrix resin, phosphonium salt intercalated modified montmorillonite added as a synergistic agent has a positive synergistic effect on the flame retardation property and the mechanical performances of the halogen-free and flame-retardant long glass fiber reinforced TPEE composite material, and a compatilizer enhances the binding force between the matrix resin and fibers and improves the compatibility between the matrix resin and a flexibilizer; a flame retardant DIDOPO has a low melting temperature and a high decomposition temperature, realizes a wide processing temperature interval selection range, and has extremely good melt fluidity; and the halogen-free and flame-retardant long glass fiber reinforced TPEE composite material is prepared through the one-step impregnation method, and the method comprises the following steps: directly uniformly mixing the flame retardant with the matrix resin and other materials, extruding the obtained mixed melt, impregnating continuous glass fibers in the mixed melt, and carrying out cooling, traction and grain-sized cutting.

Description

technical field [0001] The invention relates to the field of material science, in particular to a halogen-free flame-retardant long glass fiber reinforced TPEE composite material and a preparation method thereof. Background technique [0002] Thermoplastic polyester elastomer (TPEE) is a block copolymer containing polyester hard segments and polyether soft segments. Among them, the polyether soft segment and the uncrystallized polyester form an amorphous phase, and the polyester hard segment partially crystallizes to form a crystalline microdomain, which acts as a physical crosslinking point. TPEE has the elasticity of rubber and the strength of engineering plastics; the soft segment gives it elasticity, making it like rubber; the hard segment gives it processing properties, making it like plastic; compared with rubber, it has better processing properties and longer Service life; Compared with engineering materials, it also has the characteristics of high strength, better f...
