High-glow-wire-temperature red phosphorus flame-retardant reinforced PA (polyamide) 66 and PPE (polyphenyl ether) alloy material and preparation method thereof

Abstract

The invention discloses a high-glow-wire-temperature red phosphorus flame-retardant reinforced PA (polyamide) 66 and PPE (polyphenyl ether) alloy material and a preparation method thereof. The high-glow-wire-temperature red phosphorus flame-retardant reinforced PA66 and PPE alloy material includes the following components in each 100 parts of raw materials and content of the components, by weight, 30-50% of PA66, 10-20% of PPE, 5-20% of red phosphorus masterbatch, 20-35% of glass fibers, 5-15% of synergistic agent, 5-10% of compatilizer, 2-5% of antioxidant and 0.1-0.5% of auxiliaries. The high-glow-wire-temperature red phosphorus flame-retardant reinforced PA66 and PPE alloy material can be formed in an extrusion or injection manner by corresponding equipment such as an extruder. Compared with the conventional material, the high-glow-wire-temperature red phosphorus flame-retardant reinforced PA66 and PPE alloy material can pass the test of the GWIT (glow wire ignition temperature) of 850 DEG C, cannot be ignited, is controllable in processing and stable in flame retardant, quite fine in rigidity, high in fire resistance, stable in size and capable of meeting requirements of various electronic and electric products.

Description

technical field [0001] The invention relates to a high glow wire red phosphorus flame retardant PA66 and PPE alloy material and its preparation method, in particular to an engineering material product suitable for injection molding with high electrical performance and flame retardant enhancement requirements, suitable for low-voltage electrical appliances, circuit breakers Polyamide modified materials such as device, motor carbon brush bracket, etc., belong to the technical field of polymer modification. Background technique [0002] Nylon 66 is a homogeneous thermoplastic polymer with six symmetrical methylene groups in its molecular structure. It has the advantages of high strength, wear resistance, solvent resistance, good self-lubrication and wide temperature range. It is the most widely used One of engineering plastics, widely used in various electronic and electrical equipment and home appliances. Nearly 80% of the flame retardants used in the current flame-retardant ...
