Embodiment Construction

[0047] Such as Figure 1-4As shown, a thermal insulation integrated continuous fiber prepreg tape reinforced composite pipe and its processing method include a foam insulation pipe 1 and a heat-resistant and pressure-resistant working pipe 2. The plastic outer protective surface layer 1-1 and the foam insulation layer 1-2 are integrally formed. The heat-resistant and pressure-resistant working pipe 2 is integrally formed by a plastic inner layer pipe 2-2 and an isomorphic structural prepreg tape reinforcing layer 2-1 that is melted and wound on the outer wall of the plastic inner layer pipe 2-2. The prepreg tape reinforcement layer 2-1 is fused with the foam insulation layer 1-2, which improves the pressure and temperature resistance and overall rigidity of the working pipeline, as well as the rigidity and waterproofness of the insulation layer.

[0048] The foam insulation layer 12 is compounded with hot melt adhesive, AC foaming agent, and mixed plastics. The mixed plastics...

Abstract

The invention discloses a heat-insulating integrated continuous fiber prepreg tape enhanced composite pipe and a processing method. The heat-insulating integrated continuous fiber prepreg tape enhanced composite pipe comprises a foaming heat-insulating pipe and a heat-resistant and pressure-resistant work pipe. The processing method comprises the following steps: placing mixing an inner layer of plastic and an AC foaming agent with plastic respectively, placing the mixtures into a plastic inner layer extruder and a foaming extruder, extruding and entering a plastic inner layer mold and a foaming mold, cooling and shaping, and packaging after fusing, identifying and cutting. The heat-insulating integrated continuous fiber prepreg tape enhanced composite pipe improves the overall rigidity, the pressure and temperature resistance, waterproof property and strength; and by the processing method of the heat-insulating integrated continuous fiber prepreg tape enhanced composite pipe, the fusion mildness is improved and processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of continuous fiber prepreg tape reinforced composite thermal insulation processing, in particular to a heat preservation integrated continuous fiber prepreg tape reinforced composite pipe and a processing method. Background technique [0002] Today's pipe insulation technology is to lay low thermal conductivity insulation materials outside the pipe to achieve heat preservation and heat insulation requirements. It is widely used in thermal heating pipes, hot water delivery pipes, steam pipes, air-conditioning pipes, etc. First set up brackets on steel pipes and plastic outer walls and then wrap the outer hollow plastic pipes. Between the outer hollow plastic pipes and steel pipes and plastic outer walls, fill polyurethane foam insulation layers to form steel pipes and polyurethane foam insulation plastic pipes. [0003] This method of step-by-step production of working tubes, outer tubes, brackets, and insul...
