The invention relates to a low-creep ultraviolet flame-retardant material used in a high-frequency vibration environment, which comprises the following components in parts by weight: 100 parts of polypropylene, 40-60 parts of a flame retardant, 0.4-0.8 part of a nucleating agent, 20-40 parts of chopped glass fiber and 0.5-1.5 parts of an ultraviolet aging aid, the flame retardant is a mixture and contains 40wt% of anhydrous zinc phosphate; the anhydrous zinc phosphate is a needle-like crystal with the length-diameter ratio of (3-5): 1; the nucleating agent is a mixture of sodium 2, 2 '-methylenebis (4, 6-di-tert-butylphenyl) phosphate and di [4-tert-butylbenzoic acid] aluminum hydroxide in a mass ratio of 1: 2. The flame-retardant material provided by the invention has good strong ultraviolet aging resistance and flame retardance, and also has good creep resistance under a vibration working condition. 本发明涉及一种高频振动环境使用的低蠕变紫外阻燃材料，按重量份数计，包含100份聚丙烯、40-60份阻燃剂、0.4-0.8份成核剂、20-40份短切玻璃纤维和0.5-1.5份紫外老化助剂；阻燃剂为混合物，其中含有40wt
