Abstract

The invention provides an environment-friendly flame retardant composite filling reinforced polyamide 66 resin composition, which consists of a mixture. The mixture consists of the following compositions by weight percentage: 40 to 67 percent of nylon 66, 12 to 25 percent of red phosphorus master batch, 1 to 10 percent of compatilizer, 10 to 20 percent of glass fiber, 10 to 20 percent of talcum powder, 0.1 to 1 percent of antioxidant, and 0.1 to 1 percent of lubricant. The flame retardant polyamide composition has high-efficiency flame retardant performance with flame retardant rating reaching V0 grade of UL94 standard, greatly improves rigidity and heat resistance of nylon with good dimension stability, and belongs to an environment-friendly product. The environment-friendly flame retardant composite filling reinforced polyamide 66 resin composition is applicable to injection molding of electronic equipment and household appliances with various environment-friendly and flame retardant requirements.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant composite filled reinforced polyamide 66 resin composition, in particular to an engineering material product suitable for injection molding with high electrical insulation performance requirements and flame-retardant enhancement requirements, suitable for low-voltage vacuum contactors, circuit breakers The invention relates to polyamide modified materials for devices, low-voltage switches, thin-walled electronic and electrical components, etc., and belongs to the technical field of modified polyamides. technical background [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 hom...
