Abstract

The invention discloses a glass fiber yarn composite material and a preparation method thereof. The glass fiber yarn is composed of the following raw materials in parts by weight: 50 parts of glass fiber, 8 parts of polyacrylamide, 10 parts of tolyltriazole, 6 parts of aminopropyltrioxysilane, 2-6 parts of sodium tetraborate, 2-8 parts of sulfamic acid, 3-9 parts of diethyl succinate, 4-12 parts of glycerol, hydroxyethylidene diphosphine 4‑8 parts of acid. Under the synergistic effect of various raw materials, the present invention has high strength, large elastic modulus, high tensile strength, high temperature resistance, good tensile resistance, good impact resistance, and good chemical stability compared with ordinary alkali-free glass fibers. Good fatigue resistance and high performance. At the same time, the invention not only has reasonable formula components, stable performance, simple and easy-to-operate process, high production efficiency, but also can improve the toughness of glass fiber, is not easy to break, has good water blocking effect, and low production cost. , suitable for industrial production.

Description

technical field [0001] The invention relates to the field of communication optical cables, in particular to a glass fiber yarn composite material and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent properties, and there are many kinds. The elastic modulus of glass fiber exceeds 86Gpa. Compared with ordinary alkali-free glass fiber, high-strength and high-modulus glass fiber has excellent properties such as high tensile strength, high elastic modulus, good impact resistance, good chemical stability, good fatigue resistance, high temperature resistance, etc., and can be widely used apply to [0003] Aerospace, aviation, weapons and other fields that have strict requirements on the performance of composite materials. [0004] However, the disadvantage of glass fiber is that it is brittle and has poor wear resistance. Existing glass fibers have the disadvantages of low tensile strength, low elastic m...
