Embodiment 1-11

[0047] The preparation process of the functional filler pretreatment and the functional flame retardant polymer composition is as follows: Weigh the functional filler and the interface modifier and place them in a high-speed mixer. After mixing for 2 minutes, add the polymer matrix material and compatibilizer , flame retardant, additives, etc., continue to mix for 3 minutes. The mixed materials are introduced into a Leistritz twin-screw extruder for melting, kneading, extrusion, and granulation to obtain functional flame-retardant polymer compositions A1-A11. The temperature of each section of the twin-screw extruder is 150 to 180°C, 170 to 200°C, 200 to 250°C, 220 to 280°C, 250 to 300°C, and the screw speed is 100 to 300 rpm.

[0048] Sample injection molding: BOY 55M injection molding machine was used to inject A1-A11 into standard splines. Perform the test after constant temperature and humidity treatment according to the standard requirements. The performance test result...

Abstract

The invention relates to a functional flame-retardant polymeric composition and a preparation method and application thereof and mainly solves the problem that the prior art has high usage of a functional filler, causing lower impact toughness to a material and poor flame retardance. The functional flame-retardant polymeric composition includes, by mass: a) 30-70% of a polymeric base material; b)10-50% of a functional filler; c) 1-20% of a modifier, wherein the modifier includes an interfacial modifier and a compatibilizer having a mass ratio of (0.01-5):(0.5-20); d) 0.1-15% of a flame retardant; and e) 0.01-10% of an aid; the problem is well solved; the functional flame-retardant polymeric composition is applicable to the industrial production in the fields, such as electronics, electrical appliances, and automobiles.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and relates to a functional flame-retardant polymer composition and a preparation method and application thereof. The functional flame retardant polymer composition is suitable for the fields of electronics, electrical appliances, automobiles and the like. Background technique [0002] With the continuous improvement of the flame retardant properties of electronic and electrical products, the research on polymer flame retardant modification has become more and more important. There are many types of flame retardants, including halogen-containing, organophosphorus, organosilicon, organic sulfonates, and phosphazene compounds. Halogenated flame retardants have serious environmental pollution problems and have been banned in many countries. The decomposition temperature of the organophosphorus flame retardant itself is lowered, and the addition amount is large, which will greatly damage ...
