Embodiment 1

[0033] Such as figure 1 with figure 2 As shown, a fiber-reinforced hose is composed of a fiber-reinforced braided layer 1, an outer rubber layer 2 and an inner rubber layer 3. The fiber-reinforced braided layer 1 is tubular and woven from warp and weft threads. The inner rubber Layer 3 and cover layer 2 are respectively coated on the inner surface and the outer surface of braided layer 1, and several columnar adhesives 4 are permeated in the fiber gap of hose fiber reinforced braided layer 1, and the outer rubber layer 2 passes through the gap of braided layer The columnar rubber 4 is connected with the inner rubber layer 3 and forms an integral structure.

[0034] In this embodiment, the warp includes nylon fiber, polyester fiber and PEN fiber; or, the warp is twisted from nylon fiber and polyester fiber or PEN fiber; the weft is twisted from aramid fiber ; The tensile strength of the weft is 1 to 5 times that of the warp. The inner rubber layer 3, the outer rubber layer ...

Embodiment 2

[0036] A method for manufacturing a fiber-reinforced hose, comprising the following steps: 1. Material selection: According to the working pressure, caliber and length required by the fiber-reinforced hose, calculate the specifications and quantities of the warp and weft, use nylon fibers for the warp, and use nylon fibers for the weft. Using aramid fiber, the tensile force that the weft can withstand is 0.8 times that of the warp; 2. Twisting: use a twisting machine to twist the warp and weft respectively and make warp and weft spindles; 3. Upper line: Put the warp thread spindle and the weft thread spindle on the circular loom; 4, weaving: use the circular loom to weave the warp thread and the weft thread into a tubular fiber braided reinforcing layer, and set uniform gaps on the fiber braided reinforcing layer; 5, bake: Transfer the fiber-reinforced braided layer to an oven for full baking; 6. Coating: transfer the baked fiber braided layer to the die head, which is divided ...

Embodiment 3

[0039] A method for manufacturing a fiber-reinforced hose, comprising the following steps: 1. Material selection: According to the working pressure, caliber and length required by the fiber-reinforced hose, calculate the specification and quantity of the warp and weft, use polyester fiber for the warp, The weft thread uses aramid fiber, and the tensile force that the weft thread can withstand is the same as that of the warp thread; 2. Twisting: use a twisting machine to twist the warp thread and weft thread respectively and make a warp thread spindle and a weft thread spindle; Warp yarn spindles and weft yarn spindles are put on the circular loom; 4, weaving: use circular loom to weave the warp and weft threads into a tubular fiber-reinforced braided layer, and set uniform gaps on the fiber braided layer; 5, bake: the fiber The braided layer is transferred to the oven for full baking; 6. Coating: transfer the baked fiber braided layer to the die head, the die head is divided in...

Abstract

The invention relates to a fiber reinforced hose and a manufacturing method thereof. The hose is composed of a fiber reinforced woven layer, an inner glue layer and an outer glue layer, wherein the fiber reinforced woven layer is a tubular shape and is formed by weaving warp yarns and weft yarns, the inner glue layer and the outer glue layer coat the inner surface and the outer surface of the woven layer respectively, a plurality of columnar glue permeates into the fiber gaps of the woven layer of the hose, the outer glue layer is connected with the inner glue layer through the columnar glue;and the manufacturing method of the fiber reinforced hose comprises the procedures of material selection, twisting, yarn feeding, weaving, baking, coating and cooling, a liquid glue layer material coats the inner and outer wall of the woven layer by a die head and an extruding machine after baking is carried out, and the hose is obtained by cooling. According to the hose and the method, the proportion of the maximum tensile force borne by the warp yarns and the weft yarns is reasonably configured, enough strength is generated by using the minimum amount of aramid fibers as the weft yarns, so that the production cost is reduced; and the inner glue layer and the outer glue layer simultaneously coat on the inner wall and the outer wall of the fiber reinforced layer through a one-step coatingprocess, and the production efficiency and the strength of the hose are improved.

Description

technical field [0001] The invention relates to the technical field of water pipes, in particular to a fiber-reinforced hose suitable for high-pressure fluid delivery and a manufacturing method thereof. Background technique [0002] Fiber-reinforced hose refers to a positive-pressure conveying hose whose reinforcement layer is fiber fabric and coated with various rubber materials inside and outside. Smaller; the inner and outer rubber layers are thinner, the total wall thickness is about 2-4mm, the weight of the pipe body is lighter, and the operation is convenient; the length of a single hose is longer, there are fewer joints when forming a pipeline, the speed of expansion and retraction is fast, and the emergency response capability powerful. Such hoses include long-distance oil or water hoses, fire hoses, farmland irrigation hoses, urban emergency water supply hoses, etc. Among them, the fiber-reinforced hose for fire protection is required to be light in weight, easy t...
