This invention relates to the field of
polymer materials technology, and discloses a low-temperature resistant and high-
impact protective
face shield material and its preparation method. The protective
face shield material of this invention comprises the following raw materials in parts by weight: 55-70 parts of nylon 66, 5-15 parts of nylon 6, 5-12 parts of a low-temperature
toughening agent, 4-10 parts of a high-temperature resistant additive, 0.5-1 part of
oleamide, 0.2-0.5 parts of
silane coupling agent 550, 0.2-0.5 parts of an
antioxidant, and 0.5-1.5 parts of an
ultraviolet absorber. The low-temperature
toughening agent of this invention can improve the
impact resistance of nylon materials in low-temperature environments, maintaining excellent
impact strength even at low temperatures. The high-temperature resistant additive gives the
nylon material excellent high-temperature
thermal stability, avoiding problems such as
softening deformation, yellowing
cracking, and
mechanical property degradation at high temperatures.
