Abstract

The invention relates to a wear-resistant fiber sleeve and a preparation method thereof. The wear-resistant fiber sleeve is made of a composite material, and the composite material includes 40-60 parts of nitrile rubber and 20-35 parts of glass in parts by mass. Fiber, 5-10 parts polyethylene, 2-10 parts N-glycine-based maleamic acid, 0.2-0.5 parts initiator, 3-8 parts silicon carbide, 0.8-1.5 parts silane coupling agent, 0.1-0.2 antioxidant agent, N-glycine-based maleamic acid is grafted to nitrile rubber and polyethylene to modify the two to improve their strength and mechanical properties, and the silane coupling link is used to modify the glass fiber to increase its strength. Then compound the nitrile rubber, polyethylene and glass fiber, and the composite material is used to prepare the fiber casing. The obtained fiber casing has good wear resistance and can well meet the market demand.

Description

technical field [0001] The invention relates to a fiber sleeve, in particular to a wear-resistant fiber sleeve and a preparation method thereof. Background technique [0002] Existing silicone resins for fiberglass sleeves or inner rubber tubes often use silicone resins with a solid content of 30%, which have the characteristics of soft gelatin, easy curing and convenient use. However, with the improvement of the standard of colloidal coating and aging resistance in the glass fiber casing industry, most silicone resins are not ideal in wear resistance, and it is difficult to meet the needs of some high-strength casings. For example, the invention patent with the Chinese patent application number "201610527821x" discloses a wear-resistant glass fiber communication pipe and its preparation method, which is composed of PVC, calcium carbonate, glass fiber, impact modifier, stearic acid, Ca / Zn compound Stabilizer, PE wax composition. The invention finds through experiments that...
