An alkali-free ultrafine glass fiber formula includes the following components, in mass percentage calculated based on 100 Kg: SiO2: 50% to 65%, AlO: 10% to 16.5%, CaO: 17% to 28%, MgO: 0.2% to 4.0%, NaO and KO: 0.1% to 0.8% in total, CeO: 0.1% to 0.5%, LiO: 0.1% to 0.7%, FeO: 0.05% to 0.6%, TiO: 0.1% to 1%, and impurities: the balance. In the preparation of alkali-free ultrafine glass fibers, no fluorine and boron-containing raw materials are used, and CeOand LiO are introduced, which avoids the use of BOand F that have a large impact on the environment, and reduces environmental pollution. A single fiber strength of prepared glass fibers is about 9% higher than that of the traditional E glass fibers, and the comprehensive performance of a prepared glass fiber product is significantly superior than that of the existing E glass fiber product. 1.
