The invention discloses an ultraviolet curing high-temperature-resistant optical fiber inner layer coating. The coating is prepared from the following components: 50 to 80 percent of acrylate oligomer A, 15 to 40 percent of organic silicon modified acrylate oligomer B, 15 to 50 percent of acrylate monomer, 2 to 10 percent of photoinitiator, 0.3 to 2 percent of antioxidant and 1 to 2 percent of coupling agent. Compared with common high-temperature-resistant optical fiber inner-layer coatings on the market, the coating has the advantages of excellent high-temperature resistance, low glass transition temperature, simple production process and good storage stability, and can be used in a wider temperature range. 本发明公开了一种紫外光固化耐高温光纤内层涂料；所述涂料组成包括：丙烯酸酯低聚物A 50-80％，有机硅改性丙烯酸酯低聚物B 15-40％，丙烯酸酯单体15-50％，光引发剂2％-10％，抗氧剂0.3-2％，偶联剂1-2％。相较于市面上常见的耐高温光纤内层涂料，该涂料具有极佳的耐高温性能，且玻璃化转化温度低，可在更宽温程使用，生产工艺简单，储存稳定性良好。
