Description
Technical Field
The invention 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, embedded parts (prefabricated embedded parts) refer to components which are pre-installed (embedded) in concealed works, namely structural parts which are arranged during structure pouring and are used for lap joint during building of a superstructure. So as to be beneficial to the installation and fixation of the external engineering equipment foundation. As shown in fig. 6, the embedded part 4 includes a base plate 41 and a plurality of beam columns 42 disposed on one side of the base plate 41, and during actual construction, the beam columns 42 are generally formed by bending two ends of a steel bar, wherein one end is welded to the base plate 41.
The carbon fiber is an inorganic material prepared by decomposing organic matrix fiber under the inert gas at the high temperature of 1000-3000 ℃, and all elements except carbon are removed in the oxygen-free high-temperature treatment process, so that the final carbon content is more than 90%. The carbon fiber is black in appearance, hard in texture, high in strength, light in 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 of the carbon fiber can reach 5 times of that of the steel (strength: 580/122ksi), so the carbon fiber has a 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 knitting waste leftover materials, part of the fibers or the knitting waste leftover materials are processed into chopped fibers and milled fibers, but a large amount of fibers are still not utilized, most of the waste silk and the waste leftover materials cannot be processed or are extremely difficult to comb, and the effective utilization rate of the fibers is greatly reduced.

step S3: placing the threaded hose assembly in a mold for curing molding to form a carbon fiber rod;
step S4: and compounding a plurality of carbon fiber rods and the bottom plate into an embedded part.
Further, between the steps S1 and S2, a step SA is further included,

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. 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 the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1:
referring to fig. 1 to 7, it can be seen that the method for recycling carbon fiber waste filaments and fabric leftover materials in the building construction field according to the embodiment of the present invention includes:
step S1: preparing raw materials, namely taking recycled carbon fiber waste filaments, carbon fiber fabric leftover materials, carbon fiber felts, carbon fiber powder and scrapped carbon fiber parts as raw materials;
step S2: cutting the raw materials to a fixed length, carding, weighing in sections, soaking the raw materials into fast curing resin, and filling the fast curing resin into a threaded hose to form a threaded hose component;
step S3: placing the threaded hose assembly in a mold for curing molding to form a carbon fiber rod;
step S4: and compounding a plurality of 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 building construction field, which is provided by the embodiment of the invention, prepares the residual carbon fiber waste edges and/or waste filaments into the embedded part by matching the threaded hose with the compression molding process, is applied to the industrial field, realizes the recycling of the carbon fibers, and enhances the integral strength of the embedded part due to the material characteristics of the carbon fibers.
In the step S1, the threaded hose is formed by spirally winding a long-strip-shaped soft board, so that a certain gap is left between the sections of the body, which is convenient for the epoxy resin to be fully soaked, and secondly, the overall shape following capability can be increased, which is convenient for laying the threaded hose assembly in the mold. It will be appreciated that since the final embedment needs to be buried, the threaded hose can be cured with the carbon fiber waste edges and/or waste filaments without the need for a stripping process.
