Abstract
Description
technical field
[0001] The invention belongs to the technical field of flame-retardant polyamides, in particular to a highly flame-retardant polyamide mainly based on a branched chain alkyl phosphinate compounded with a nitrogen-containing flame retardant or a glass fiber-reinforced high flame-retardant polyamide. amides. Background technique
[0002] Polyamide is commonly known as nylon (Nylon), the English name is Polyamide (PA), and polyamide 6 and polyamide 66 are two of the most important varieties. Although polyamide has become the material of choice for the electrical and electronic industry and the automotive industry due to its good mechanical properties, chemical resistance, oil resistance and good electrical insulation, but because these fields now require high flame retardancy properties of materials, The flame retardancy of polyamide and its glass fiber-reinforced polyamide products is very poor, and its oxygen index is only 22%. Even if the thickness of polyam...
