Abstract

The invention relates to the field of high-polymer materials, and particularly relates to a high-impact halogen-free flame-retardant POK/PA (polyketone/polyamide) alloy material. The alloy material is composed of the following components in parts by weight: 200-400 parts of POK, 400-700 parts of PA6, 10-100 parts of compatibility and impact modifier, 50-150 parts of halogen-free flame retardant and 5-15 parts of aid. The high-impact halogen-free flame-retardant POK/PA alloy material has favorable high-impact properties (up to 250 J/M at 23 DEG C and up to 150 J/M at -30 DEG C); the halogen-free flame retardancy can reach V-0; the abrasion coefficient of the material is better than that of the simple flame-retardant PA6, and is up to 6.9 mm<3>/kg/km; and the heat-deformation temperature of the material is higher than that of the simple flame-retardant PA6, and is up to 190 DEG C.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-impact halogen-free flame-retardant POK / PA alloy material. Background technique [0002] Polyamide (PA6) has the characteristics of thermoplasticity, light weight, excellent mechanical properties, chemical resistance and good durability. It is generally used in auto parts, mechanical parts, electronic and electrical products, engineering accessories and other products. The disadvantages are high water absorption, large difference in strength between dry and wet environments, low notch impact, general wear resistance, and large shrinkage. [0003] Polyketone (POK) is a new type of green polymer material synthesized from carbon monoxide and olefins (ethylene, propylene). The main chain of the molecule is an engineering plastic with a tight crystal structure formed by hydrocarbons through high crystallization. It has excellent chemical resistance and impact resistance. Compa...
