Referring to fig. 1-6, the fiber resin composite honeycomb wall pipe provided by the present invention includes a spirally wound tubular strip 1, wherein turns of the tubular strip 1 are connected by a melting glue 2; the corrosion-resistant coating comprises a corrosion-resistant layer 3 and a fiber resin layer 4, wherein the corrosion-resistant layer 3 is coated on the inner side surfaces of the tubular strip 1 and the molten gel 2, and the fiber resin layer 4 is coated on the outer side surfaces of the tubular strip 1 and the molten gel 2;
the corrosion resistance of the corrosion-resistant layer 3 is stronger than that of the tubular strip 1 and the molten gel 2;
the fiber resin layer 4 includes a resin main body 401 and a reinforcing core 402 provided in the resin main body; the resin main body 401 has a hardness smaller than those of the tubular strip 1 and the melt 2.
The corrosion-resistant layer 3 is arranged on the inner surface of the fiber-resin composite honeycomb structural wall pipe, so that the corrosion resistance of the inner side surface is improved, the fiber resin layer 4 is arranged on the outer surface of the fiber-resin composite honeycomb structural wall pipe, the resin main body 401 of the fiber resin layer is low in hardness, high in flexibility and good in buffering capacity, and the reinforcing core 402 in the fiber resin layer can play a role in enhancing toughness, so that the fiber resin layer 4 is not easy to crack due to extrusion; it can be seen that, under the same other conditions, the fiber-resin composite honeycomb structural wall pipe has stronger flexibility of the outer surface, better corrosion resistance of the inner surface and longer service life compared with the hollow-wall wound pipe in the prior art.
The reinforcing core 402 includes at least one of a ribbon-shaped reinforcing core and a wire-shaped reinforcing core. For example, the reinforcing core 402 in fig. 1, 3, and 5 is a linear reinforcing core, and the reinforcing core 402 in fig. 2, 4, and 6 is a ribbon-shaped reinforcing core. Although only one shape of core is shown, it is not limited to this, and it is also possible to include both ribbon and wire cores, and the different shapes of the core 402 may be the same or different.
In some embodiments, the reinforcing core 402 comprises at least one of a metal reinforcing core, a plastic reinforcing core, and a fiber reinforcing core.
The metal reinforcing core, such as (but not limited to) a steel reinforcing core, an aluminum reinforcing core, etc., may be made of metal in a band shape, or may be made of metal in a wire shape, or may be made of metal in a fiber shape and then woven in a band shape or a wire shape; if the metal fibers are woven into a ribbon or thread, the metal fibers may be woven from one metal fiber or a plurality of metal fibers.
The plastic reinforcing core, such as a polypropylene reinforcing core, a polyethylene reinforcing core, and the like (without limitation), may be made of plastic in a band shape directly, or may be made of plastic in a thread shape directly, or may be made of plastic in a fiber shape first and then woven in a band shape or a thread shape; if the plastic fiber is woven into a band or thread, the plastic fiber or the plastic fibers can be woven.
The fiber-reinforced core may be, for example (but not limited to), a glass fiber-reinforced core, a polyester fiber-reinforced core, a carbon fiber-reinforced core, or the like, and one or more kinds of fibers may be woven in a band-like or thread-like form, or a long fiber may be directly used as the reinforced core.
In some embodiments, the reinforcing core 402 is spirally wound, for example, the fiber resin layer 4 is made by spirally winding a fiber resin tape including several reinforcing cores 402 on the outer side of the tubular tape 1 and the molten glue 2.
In some preferred embodiments, the melt 2 includes a first melt 201 on the inner side and a second melt 202 on the outer side, the first melt 201 having a hardness greater than that of the resin body 401, and the second melt 202 having a hardness between that of the first melt 201 and that of the resin body 401. Because the hardness gradually transits from outside to inside, the hardness mutation rate between the inner layer and the outer layer is reduced, thereby reducing the mutation rate of stress deformation generated between the inner layer and the outer layer, optimizing the pipe wall structure and further prolonging the service life.
The tubular strip 1 may be in the shape of a square tube, a circular tube, or an ellipse-like tube. For example, in fig. 1 and 2, the tubular strip 1 is in a square tube shape; in fig. 3 and 4, the tubular strip 1 is in a circular tube shape; in fig. 5 and 6, the tubular strip 1 is an elliptical tube, and in the cross section of the tubular strip 1, both sides in the width direction (i.e., the axial direction of the fiber-resin composite honeycomb-structured wall tube) are circular arc lines, and both sides in the thickness direction (i.e., the radial direction of the fiber-resin composite honeycomb-structured wall tube) are straight lines or arc lines (the curvature of which is smaller than the curvature of both sides in the width direction). When the tubular strip 1 is in a circular tube shape or an ellipse-like tube shape, the middle of the molten rubber 2 between the turns is small, the two sides of the molten rubber are large, mutual sliding and dislocation (sliding and dislocation in the vertical direction in the figure 1) between the turns can be effectively prevented, and the tube is not easy to break due to degumming under the action of shearing force.
In some preferred embodiments, the tubular strip 1 has a plurality of apertures 101, the apertures 101 extending along the length of the tubular strip 1. Because a plurality of pipe holes 101 are formed in the tubular strip 1, the tubular strip has strong vibration reduction and shock resistance, and can be used in areas with multiple earthquakes for a long time.
Wherein, the plurality of pipe holes 101 of the tubular strip 1 comprise at least one of round holes, elliptical holes, polygonal holes (triangle, rectangle, pentagon, hexagon, etc.), fan-shaped holes and other special-shaped holes. The plurality of pores 101 of the tubular strip 1 may be of the same shape or of different shapes, and the pores 101 of the same shape may be of the same or different sizes (for example, fig. 3 and 4 include pores 101 of the same shape but different sizes).
In some embodiments, the plurality of holes 101 of the tubular strip 1 includes a plurality of groups of holes distributed in a ring shape, each group including a plurality of holes uniformly distributed on the same circumference. For example, in fig. 3 and 4, the tubular strip 1 is a circular tube, and includes a set of annularly distributed pipe holes 101 (but not limited to one set), and the number of the pipe holes in each set is six (but not limited to six in the figure); in some embodiments, further comprises a pipe hole 101 for centering the tubular strip 1. In fact, in this distribution method, the tubular strip 1 is not limited to a circular tube shape, and the pipe holes 101 are not limited to circular holes, and if a plurality of sets of annularly distributed pipe holes 101 are provided, the shapes of the pipe holes 101 in each set may be the same or different, the sizes of the pipe holes 101 in each set may be the same or different, and the number of pipe holes in each set may be the same or different.
In some embodiments, the plurality of apertures 101 of the tubular strip 1 are arranged along the width of the tubular strip. So that between adjacent holes 101 there are supporting walls 102 to improve the compression resistance of the tubular strip 1 itself. For example, in fig. 5 and 6, the tubular strip 1 is an elliptical tube, and includes two tube holes 101 arranged in the width direction, and the tube holes 101 are circular holes. In fact, for this distribution, the tubular strip 1 is not limited to being an oval-like tube, the tubular holes 101 are not limited to being circular holes, and the number of the tubular holes 101 is not limited to two.
In some embodiments, the plurality of holes 101 of the tubular strip 1 are arranged in a matrix. For example, in fig. 1 and 2, the tubular strip 1 is a square tube and includes rectangular tube holes 101 distributed in a 3 × 3 dimensional matrix. In fact, for this distribution, the tubular strip 1 is not limited to being square tubular, the tubular holes 101 are not limited to being rectangular holes, and the dimension of the matrix is not limited to 3 x 3.
In order to further improve the strength of the fiber resin composite honeycomb-structured wall pipe, a support frame, such as a cross-shaped frame, a prism-shaped tube frame (a triangular prism-shaped tube frame, a quadrangular prism-shaped tube frame, a pentagonal prism-shaped tube frame, etc.), a plate-shaped frame, etc., may be provided in the tube hole 101 of the tubular strip 1; in fact, the support framework in different apertures 101 may be the same or different.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
