Continuous carbon fiber winding composite reinforced hollow wall winding pipe and preparation method thereof

Abstract

The invention discloses a continuous carbon fiber winding composite reinforced hollow wall winding pipe and a preparation method thereof, and relates to the technical field of pipe processing. The preparation method of the continuous carbon fiber winding composite reinforced hollow wall winding pipe comprises the following steps of: step 1, processing a part A and a part B of a base layer through an extruder; 2, winding, compounding and molding the part A and the part B to obtain a base layer; 3, winding the reinforcing layer to the outer side of the base layer through a winding device; and 4, spraying a mixture to the inner wall of the base layer through a spraying device, and forming a protective layer after drying. According to the The invention discloses a continuous carbon fiber winding composite reinforced hollow wall winding pipe and the preparation method thereof, by additionally arranging the carbon fiber layer on the outer side of the base layer of the hollow winding pipe, the tensile strength, shearing resistance and shock resistance of the pipe can be improved, and meanwhile, as the winding device is adopted for machining, a winder in the winding device can be better attached to the concave portion and the convex portion of the winding pipe body through a connecting roller, and therefore, the winding quality can be improved.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a continuous carbon fiber winding composite reinforced hollow wall winding pipe and a preparation method thereof. Background technique [0002] Hollow winding pipe is a kind of pipe material that is formed by winding and welding with high-density polyethylene as raw material. Due to its unique forming process, it can produce pipes with a diameter of up to 3 meters, which is difficult to complete by other production processes. Due to its excellent melting and welding performance, high-density polyethylene not only guarantees the product molding process and product quality, but also provides a variety of reliable methods for construction connection. The hollow winding pipe has stable chemical properties and strong acid, alkali and salt resistance; Strong impact resistance, pressure resistance; aging resistance, light weight and other characteristics.

Problems solved by technology

[0004] When the existing hollow wound pipe is used, it needs to have greater tensile, shear and shock resistance in some working environments, so it is necessary to add carbon fiber to the hollow wound pipe, and after a long time of use, the hollow wound pipe will The aging degree of its inner wall is faster
