Abstract

The invention discloses a glass fiber reinforced PE water supply pipe and a preparation method thereof. The PE water supply pipe is formed by compositing an inner layer, a core layer and an outer layer, wherein an inner transition reinforcing layer is arranged between the inner layer and the core layer; an outer transition reinforcing layer is arranged between the core layer and the outer layer; the core layer is a layer wound by a pretreated glass fiber tape; both the inner layer and the outer layer adopt HDPE resin with good wear resistance, tensile resistance and chemical stability as a main component; and the inner layer has good pressure resistance, antibacterial property and aging resistance. The difference between the outer layer and the inner layer lies in that the HDPE resin content is increased, expanded graphite is replaced with polytetrafluoroethylene micro-powder which is high in flame retardance, good in compatibility and self-lubricating, and thus the heat resistance, flame retardance and wear resistance of the outer layer are improved; the inner layer and the outer layer are assisted by the inner transition reinforcing layer and the outer transition reinforcing layer, so that the core layer wound with the pretreated glass fiber tape is tightly wound therein, and the compression resistance and tensile strength of the PE water supply pipe are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipe materials, in particular to a glass fiber reinforced PE water supply pipe and a preparation method thereof. Background technique [0002] Due to the low heat resistance, low hardness, heat sensitivity and easy creep of polyethylene, it is often difficult for a single polyethylene material to meet the requirements of special working conditions such as load and high speed, and it often needs to be improved by blending and compounding. sex. Continuous glass fiber reinforced polyethylene composite pipe is a pipe made of high-strength thermoplastic continuous glass fiber prepreg tape, which is continuously wound and formed as the core layer, and is composited with inner and outer thermoplastic polyethylene plastics by extrusion molding. [0003] Prior art (CN106523801A) discloses a glass fiber reinforced polyethylene water supply pipe, including a pipe body, the pipe body is composed of an inner layer, a...
