Embodiment Construction

[0015] The technical solution of the present invention will be described in detail below.

[0016] A high modulus basalt fiber composition according to the embodiment of the present invention comprises the following components according to weight percentage:

[0017]

[0018] As a preferred example, the basalt fiber composition includes the following components in terms of weight percentage:

[0019]

[0020]

[0021] Preferably, the SiO 2 and Al 2 o 3 The sum of the weight percentages is less than or equal to 67.6wt%.

[0022] Preferably, the Na 2 The weight percentage of O is greater than K 2 The weight percentage of O. due to Na + The radius of the glass is smaller than that of K+. If the content of K is too much, the strength of the R-O bond will decrease, the structure of the glass will tend to relax, and the elastic modulus will also decrease.

[0023] Preferably, the ion packing density of the high modulus basalt fiber composition is ≥56.1%, and the den...

Abstract

The invention discloses a high-modulus basalt fiber composition which has good mechanical performance. Tensile modulus can reach 107GPa, heat stability and chemical stability are enhanced, raw materials are easily obtained, production cost is low, and large-scale industrial production can be realized. The high-modulus basalt fiber composition comprises 47-56.6% of SiO2, 13-15.9% of Al2O3, 9.5-18%of Fe2O3+FeO, 6.7-9.2% of CaO, 5.2-7.8% of MgO, 0.9-3.0% of TiO2, 2.7-3.1% of Na2O and 0.5-2.3% of K2O.

Description

technical field [0001] The invention belongs to the technical field of fiber materials, and in particular relates to a high modulus basalt fiber composition. Background technique [0002] Continuous Basalt Fiber (Continuous Basalt Fiber, referred to as basalt fiber) is a continuous fiber made of natural volcanic rock (basalt or andesite) ore, which is melted at high temperature and drawn through a platinum-rhodium bushing. Basalt fiber not only has mechanical properties such as high tensile strength, high elastic modulus, and creep resistance, but also has excellent resistance to alkali and salt chemical erosion. The mechanical indexes of basalt fiber are higher than ordinary glass fiber. Long-term mechanical properties such as creep resistance and fatigue resistance, basalt fiber is better than glass fiber and aramid fiber. In civil engineering, transportation, marine engineering, etc., basalt fiber can replace ordinary carbon fiber. Basalt fiber can be regarded as a hig...
