Abstract

The invention discloses a high strength glass fiber yarn and a preparation method and application thereof. The glass fiber yarn is composed of the following raw materials according to parts by weight: 35-43parts of glass fibers, 8-16 parts of mercaptoethanol, 1-8 arts of methoxypolyethylene glycols, 3-10 parts of hydroxyethylidene diphosphonic acid and 16-24 parts of polydimethyldiallylammonium chloride. The glass fibers are put into the prepared mercaptoethanol solution, heated and stirred under the protection of nitrogen, then polydimethyldiallylammonium chloride is slowly added dropwise, heated and stirred, and the methoxypolyethylene glycols solution is added, heated and stirred; then the hydroxyethylidene diphosphonic acid is added, heated and stirred to obtain the treated glass fiber; and extruding, drawing and rolling are carried out to obtain the glass fiber yarn. The glass fiber yarn is low in density, high in tensile strength, large in elastic modulus, low in elongation at break, high in temperature resistance, capable of achieving obvious rat biting prevention effects, stable in performance, not easy to break, excellent in water blocking effects, low in production cost and suitable for industrial production, technological process is simple and tenacity is enhanced.

Description

technical field [0001] The invention relates to the field of communication optical cables, in particular to a high-strength glass fiber yarn and a preparation method and application thereof. Background technique [0002] In the field of optical cables, there are mainly two types of fiber yarns used. One is polyester fiber yarn and synthetic fiber yarn, which have the advantages of low cost, but the disadvantages are low tensile strength, low elastic modulus, and high elongation at break. The other is aramid fiber yarn, which has the advantage of good mechanical properties, but its disadvantage is that the cost is too high. Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. Glass fiber products are widely used in various fields of the national econo...
