Glass fiber rope for reinforcing polyethylene pipeline and preparation method of glass fiber rope

Abstract

The invention discloses a glass fiber rope for reinforcing a polyethylene pipeline and a preparation method of the glass fiber rope. The surface of a glass fiber bundle of the glass fiber rope is coated with modified polyethylene, wherein the modified polyethylene comprises the following components in parts by weight of 100 parts of high-density polyethylene (HDPE), 20 parts of nylon 6, 30 parts of TPV and 10 parts of ethylene-propylene-diene monomer (EPDM). The glass fiber rope has the advantages of being light in weight, high in tensile strength, good in toughness, small in creep deformation, good in heat resistance, uniform in glass fiber distribution, stable in mechanical property, recyclable and the like, can be directly wound and woven, and can be used for reinforcing thermoplastic pipelines such as the polyethylene pipe and the like.

Description

technical field [0001] The invention relates to a glass fiber rope, in particular to a glass fiber rope for reinforcing polyethylene pipes and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material, brittle, not wear-resistant, and cannot be directly used as a reinforcement material for polyethylene composite pipes. Using HDPE (high-density polyethylene) to infiltrate glass fibers to prepare resin-coated fibers is a potential solution to this problem . [0003] However, after HDPE is heated and melted, due to the high melt viscosity, it cannot effectively infiltrate the glass fiber, so it is difficult to coat the glass fiber surface with resin. In addition, effective interfacial bonding cannot be formed between the matrix resin and the glass fiber, resulting in low tensile strength. As shown in Table 1, it is the composite of glass fiber without resin coating and HDPE directly coated on the surface of glass fiber. Comp...
