Abstract

The invention belongs to the technical field of material science, and discloses a creep resistance continuous glass fiber reinforced polyethylene prepreg tape and a preparation method thereof. The polyethylene prepreg tape is prepared from the following components, by weight: 100 parts of a polyethylene matrix, 10-30 parts of a creep resistance modifier, 3-5 parts of a compatibilizer, 0.6-1.2 parts of an antioxidant, and 40-60 parts of glass fibers. The preparation method comprises: sequentially adding 100 parts of a polyethylene matrix, 10-30 parts of a creep resistance modifier, 3-5 parts of a compatibilizer, and 0.6-1.2 parts of an antioxidant to a high speed mixer, uniformly mixing, and sealing, wherein a mixing speed is 400-600 r / min, and a mixing time is 60-160 s; and extruding the obtained mixture, carrying out laminating on 40-60 parts of preheated glass fibers, and carrying out cooling and shaping on the laminated continuous glass fiber tape material to obtain the creep resistance continuous glass fiber reinforced polyethylene prepreg tape. The polyethylene prepreg tape has characteristics of excellent mechanical property and ultra-strong creep resistance.

Description

technical field [0001] The invention belongs to the technical field of material science and relates to a creep-resistant continuous glass fiber reinforced polyethylene prepreg tape and a preparation method thereof. Background technique [0002] Continuous glass fiber reinforced polyethylene prepreg tape has excellent mechanical properties. Due to the good softness of polyethylene prepreg tape, it can form a good interface with the base material of the pipeline, so polyethylene prepreg tape is used as a pipeline reinforcement material received more and more attention. However, pipelines are often served in dynamic working environments such as high temperature and long-term loads. In actual use, prepreg tapes will show shortcomings such as low impact performance, poor creep resistance and aging resistance. Among them, creep refers to the phenomenon that the deformation of materials develops gradually over time under the action of constant temperature and constant stress. The...
