Abstract

The invention belongs to the technical field of material science, and relates to a continuous fiber reinforced polyethylene prepreg tape, a preparing method therefor and an application thereof. The prepreg tape comprises, by weight, 100 parts of polyethylene matrix, 5-8 parts of a flexibilizer, 3-5 parts of a compatilizer, 0.6-1.2 parts of an anti-oxidant and 40-60 parts of glass fibers. The flexibilizer continuous glass fiber reinforced polyethylene prepreg tape is of excellent flexibility, and can form good interface combination with a pipeline base material, so that a problem of poor combination between matrix resin and the prepreg tape employed as a pipeline reinforcing material is solved.

Description

technical field [0001] The invention belongs to the technical field of material science, and relates to a continuous fiber reinforced polyethylene prepreg tape and its preparation method and application. Background technique [0002] As the profit in the field of home decoration pipes is getting lower and lower, the development of high value-added pipe products has received more and more attention. However, it is used in special fields such as oil pipelines, mines, etc., and the main substitute products are steel strips, steel mesh, steel wire reinforced plastic pipes and steel pipes. However, due to the reinforcement of steel wire and steel mesh, the weight of the pipe is relatively heavy, and transportation and installation are very inconvenient. Therefore, the development of lightweight, high-strength reinforcement materials has attracted more and more attention. Contents of the invention [0003] The object of the present invention is to provide a polyethylene prepreg...
