Abstract

The invention belongs to the technical field of composite hoses, and particularly relates to a fiber reinforced heat insulation composite hose and a manufacturing method thereof. The fiber reinforcedheat insulation composite hose comprises a reinforcing layer, wherein the reinforcing layer comprises an inner lining layer and a strip blank compounded on the outer surface of the inner lining layerin a hot melting manner, the outer surface of the strip blank is sequentially provided with a hot melt adhesive film layer and a heat insulation layer, and the heat insulation layer is made from a microcapsule foam material. One-step forming co-extrusion process is used for manufacturing. The fiber reinforced heat insulation composite hose has the beneficial effects that high strength and good heat and cold insulation effects are achieved while the light weight and softness of material are maintained, an all-in-one forming method is adopted, and simplicity, convenience and efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of composite hoses, and in particular relates to a fiber-reinforced heat-insulating composite hose and a manufacturing method thereof. Background technique [0002] Fiber-reinforced composite hose is a commonly used pipeline for fluid and gas transportation. It has the characteristics of flexibility, pressure resistance, and flexible transmission lines. It is especially suitable for fire hoses, agricultural hoses, oil and gas transportation and other applications. Compared with hard pipes, composite hoses have the characteristics of light weight, foldable, reelable, easy installation and use, etc., and are widely used in emergency rescue, oil and gas transportation and other purposes. [0003] As a pipeline for fluid transmission, different regions or fields have different application environments. For example, the temperature in northern my country will reach minus 40°C in winter, and the temperature in sou...
