Description
Technical Field
The application relates to the technical field of building construction, in particular to a method for recycling carbon fiber waste silk and braided fabric leftover materials in the field of building construction.
Background
In the field of building construction, an embedded part (prefabricated embedded part) refers to a member which is pre-installed (embedded) in a concealed project, namely a structural member arranged during structure pouring and is used for lapping when a superstructure is built. So as to be beneficial to the installation and fixation of the foundation of the external engineering equipment. As shown in fig. 6, the embedded part 4 includes a bottom plate 41 and a plurality of beam columns 42 disposed on one side of the bottom plate 41, and in actual construction, the beam columns 42 are generally formed by bending two ends of a reinforcing steel bar, wherein one end of each beam column is welded with the bottom plate 41.
The carbon fiber is an inorganic material prepared by decomposing organic matrix fiber under the condition of inert gas at the high temperature of 1000-3000 ℃, and all elements except carbon are removed in the anaerobic high-temperature treatment process, so that the final carbon content is more than 90%. The carbon fiber has black appearance, hard texture, high strength, light weight and the like. The weight of the carbon fiber is only one fourth of that of steel (specific gravity: 1.8/7.82), but the strength can reach 5 times of that of steel (strength: 580/122 ksi), so the carbon fiber has very wide application prospect in engineering.
At present, the domestic carbon fiber production and processing industry can produce a large amount of waste silk and braided fabric waste leftovers, part of fibers or braided fabric waste leftovers are processed into chopped fibers and milled fibers, but a large amount of fibers are not utilized, and most of messy silk and waste leftovers cannot be processed or are extremely difficult to comb, so that the effective utilization rate of the fibers is greatly reduced.

step S2: cutting and carding the raw materials to a fixed length, weighing the raw materials in sections, soaking the raw materials in the fast-curing resin, and filling the raw materials into a threaded hose to form a threaded hose assembly;
step S3: placing the threaded hose assembly in a mould for solidification and forming to form a carbon fiber rod;
step S4: and compounding the carbon fiber rods and the bottom plate into an embedded part.
Further, between the steps S1 and S2, a step SA is further included,
step SA: the raw materials are put into a threaded pipe and twisted according to the performance requirement to form a whole.
Further, the method also comprises a step SB,
step SB: and winding a layer of film on the outer surface of the carbon fiber filled complete integral threaded pipe fitting.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
Example 1:
referring to fig. 1 to 7, it can be seen that the method for recycling carbon fiber waste and braid leftover materials in the construction field according to the embodiment of the present application includes:
step S1: preparing raw materials, namely taking recycled carbon fiber waste silk, carbon fiber fabric leftover materials, carbon fiber felts, carbon fiber powder and scrapped carbon fiber parts as raw materials;

step S3: placing the threaded hose assembly in a mould for solidification and forming to form a carbon fiber rod;
step S4: and compounding the carbon fiber rods and the bottom plate into an embedded part.
Compared with the prior art, the method for recycling the carbon fiber braided fabric leftover materials in the field of building construction provided by the embodiment of the application has the advantages that the residual carbon fiber slitter edges and/or the residual carbon fiber slitter filaments are manufactured into the embedded part through the threaded hose matched with the compression molding process, the embedded part is applied to the industrial field, the recycling of the carbon fibers is realized, and the integral strength of the embedded part is enhanced due to the material characteristics of the carbon fibers.
In the step S1, the threaded hose is formed by spirally winding a strip-shaped soft board, so that a certain gap is reserved between the sections of bodies, the epoxy resin is convenient to fully infiltrate, and the integral shape following capability can be increased, so that the threaded hose assembly is convenient to lay in a die. It will be appreciated that the threaded hose can be cured with the carbon fiber trim and/or scrap wire without the need for a stripping process, as the final embedment is required to be buried underground.
