Description
Technical field
The invention belongs to coal mining and foundation engineering thermoset glass steel anchor rod, be specifically related to a kind of manufacture method be wound around with fabric strip, relate to simultaneously and utilize the corresponding glass fibre reinforced plastics rockbolts of this fabric strip manufacture.
Background technology
In process of coal mining, need support material to ensure safety, these support materials are mainly divided into two classes: net support material and shaft-like support material; Net support material mainly contains wire netting, plastic wire etc., shaft-like support material mainly contains anchor metal: iron (or steel) anchor pole, non-metallic rock: wood bolt, bamboo anchoring-bolt, fiber reinforcement polymer bar material, this muscle material is also called FRP (fiber reinforced polymer) muscle, FRP anchor pole, glass fibre reinforced plastics rockbolts, fiber glass resin anchor pole, plastics anchor bar, resin anchor etc. sometimes, and wherein glass fibre reinforced plastics rockbolts is the most frequently used address; Net support material and shaft-like support material need to support the use better to complete coal seam anchoring, as wire netting and anchor metal, plastic wire and glass fibre reinforced plastics rockbolts.During coal mining, plastic wire and glass fibre reinforced plastics rockbolts can cut away by coal cutter, but wire netting and anchor metal can not be cut away, otherwise damage coal cutter, produce spark and may cause coal seam blast.
Consider from raising coal mining efficiency, plastic wire and glass fibre reinforced plastics rockbolts are widely used owing to easily cutting, but because the mechanical property of plastic wire and glass fibre reinforced plastics rockbolts self is more weak, be difficult to bear very large load, thus limit its application in important supported face.
In the present invention, the shortcoming poor to glass fibre reinforced plastics rockbolts self torque resistant is proposed a solution, relate to a kind of winding with the manufacture method of fabric strip and corresponding glass fibre reinforced plastics rockbolts.
Glass fibre reinforced plastics rockbolts is glued together by a certain percentage by multiply continuous glass fibre and thermoset substrate resin, adopts the composite that pull-winding technique is made, standard: MT/T1061-2008 " fiberglass-reinforced plastic rod of resin rockbolt and annex ".
Glass fibre reinforced plastics rockbolts adopts pull-winding technique to make, the concavo-convex screw thread state of its surface presentation, to increase the body of rod and resin anchoring agent cementitiousness, there are two kinds of moulding process at present: open winding is (see patent application: CN102285105A, CN201679511U, CN10231668A, CN201677495U, CN203048305U etc.) with closed winding (see patent application: CN201760535U, CN102358030A, CN202156028U etc.), they are all on the fibre bundle after impregnation, screw thread is formed by take-up strap (rope), then be heating and curing shaping, open winding needs to use the materials such as polypropylene tape, polyester belt, nylon rope (band), continuous glass-fiber RPP band and weaving continuous glass-fiber yarn, after glass fibre reinforced plastics rockbolts is shaping, there are take-up strap or rope shape materials in its surface, needs its solution divided by the concavo-convex screw thread state forming anchor surface, and closed winding needs to use closed steel wire as winding rope, after glass fibre reinforced plastics rockbolts is shaping, its surface does not have winding rope, according to the system testing of the present inventor, the glass fibre reinforced plastics rockbolts that this two kinds of modes are produced, be difficult to reach MT/T1061-2008 requirement, mainly moment of torsion does not reach the requirement of 40N.m, and the body of rod produces the anomalies such as fracture, gross distortion.
Summary of the invention
In order to make the moment of torsion of glass fibre reinforced plastics rockbolts reach MT/T1061-2008 requirement, other indexs reach requirement simultaneously, and following technical proposal is better.
Be wound around the manufacture method with fabric strip, winding fabric strip be by the fiber of longitudinal arrangement and hoop be wound around fibrous, by pull-winding device fabrication.
Concrete, the fibers encapsulation of longitudinal arrangement, at circular mold surface, implements hoop Filament-wound Machine simultaneously, and the fiber leaving circular inner mold becomes band by hauling machine, or becomes band by coil winding machine.
Concrete, the fiber of longitudinal arrangement is continuous glass-fiber roving, its line density between 4000-20000tex, or continuous glass-fiber roving, basalt fibre, carbon fiber, aramid fiber composition blended yarn, the line density of blended yarn is between 4000-20000tex.
Concrete, the fiber that hoop is wound around is the one in weaving continuous glass-fiber yarn, basalt fibre, carbon fiber, aramid fiber, and its line density is between 10-1000tex.
Concrete, winding fabric strip need with the same or analogous thermosetting resin of glass fibre reinforced plastics rockbolts in flood and form prepreg tape.
Concrete, by pull-winding device fabrication thermoset glass steel anchor rod, it is characterized in that the fiber that the fiber of winding fabric strip by longitudinal arrangement on this glass fibre reinforced plastics rockbolts surface, hoop are wound around and thermosetting resin form.
The present invention is described as follows
Produce glass fibre reinforced plastics rockbolts moulding process according to pull-winding method, although this glass fibre reinforced plastics rockbolts has take-up strap or rope in forming process, to form the concavo-convex screw thread state on glass fibre reinforced plastics rockbolts surface, final products do not have hoop take-up strap or rope.
Because glass fibre reinforced plastics rockbolts surface exists concavo-convex screw thread state, correspondingly there is problem of stress concentration, in body of rod twist process, first there is the crackle between fiber in stress concentration portion position, namely the resin between viscose fibre destroys, crackle, along diametric(al) and longitudinal development, does not reach MT/T1061-2008 requirement, and glass fibre reinforced plastics rockbolts just destroys.
The reason that this problem occurs is because glass fibre reinforced plastics rockbolts longitudinally relies on fortifying fibre to bear strength, hoop is not then owing to having fortifying fibre, resin can only be relied on to bear strength, because resin self-strength is lower, and owing to needing to add fire-retardant, antistatic additive in coal mine support, thus cause resin self-strength to decline, the cementitiousness between fiber declines.
Solving the lower principle of glass fibre reinforced plastics rockbolts anti-twisting property is the intensity increasing its hoop, the means the most easily realized are in pull-winding formed glass steel anchor rod process, utilize the material be wound around to realize increasing the intensity of glass fibre reinforced plastics rockbolts hoop, have two basic points: winding material self-bearing capacity, cementitiousness between winding material and the body of rod.
In glass fibre reinforced plastics rockbolts two kinds of moulding process, open winding needs to use the materials such as polypropylene tape, polyester belt, nylon rope (band), continuous glass-fiber RPP band and weaving continuous glass-fiber yarn, these winding material self-bearing capacity are lower and cementitiousness between they and glass fibre reinforced plastics rockbolts is less, and they are easy to adopt artificial or mechanical means releasing from glass fibre reinforced plastics rockbolts surface; Even if do not remove, they do not help raising glass fibre reinforced plastics rockbolts anti-twisting property.
In order to improve glass fibre reinforced plastics rockbolts anti-twisting property, a method easily expected is in open winding, continuous glass-fiber roving is directly utilized to use as take-up strap, by pull-winding woven glass roving fabric around on winding drum, when pull-winding produces glass fibre reinforced plastics rockbolts, longitudinal glass fibre yarn revolution of wrap wire coiling impregnation, rotation simultaneously, by continuous unwrapping wire, take-up strap is made to strangle out screw thread on longitudinal glass fibre yarn surface of impregnation, simultaneously take-up strap under tension; This mode of production makes the woven glass roving fabric being wound around drum be tightened up, because the glass fibre in woven glass roving fabric is in loose condition (of surface) (being convenient to impregnation like this), thus as easy as rolling off a log appearance laminates between loose condition (of surface) glass fibre each other, make woven glass roving fabric can not unwrapping wire smoothly, produce regular interruption, and screw thread systematicness declines.The another kind of method easily expected adopts commercialization glass fiber tape as take-up strap, this kind of glass fiber tape adopts glass fiber for textile use yarn to be raw material, by being woven into band, in patent application: mention the method in CN201679511U, this patent adopts flexible wires (illustrating) to be wound screw thread in addition more above, the flexible wires that this is wound around is removed again after formed product, due to resin can not be combined with this glass fiber tape or adhesive property very poor, little on the impact of glass fibre reinforced plastics rockbolts anti-twisting property.
In the present inventor's research, attempted two kinds of modes above, result shows that these two kinds of modes have problems, and the product of production is difficult to reach MT/T1061-2008 torque demand.
According to illustrating above, the more satisfactory scheme of winding fabric strip adopts enhancing silvalin (as main load part), and the auxiliary structure increasing its hoop winding fiber (preventing the irregular fiber of part from laminating and being difficult to unwrapping wire), in order to make resin can fully flood this fabric strip, winding fabric strip preferably with the same or analogous thermosetting resin of glass fibre reinforced plastics rockbolts in flood after form prepreg tape mode re-use.
As core of the present invention: pull-winding equipment, this equipment is the production line producing coal mine support glass fibre reinforced plastics rockbolts, domestic have many enterprises to produce similar devices, its technique is: fiber-impregnation-Mo neck winding-shaping-heating cure-traction-cutting, this equipment can produce solid and hollow glass fibre reinforced plastics rockbolts, when producing hollow glass fibre reinforced plastics rockbolts, need that fixing roundel (rod, hollow pipe) is installed and use as inner mold.Circular inner mold is extended to hauling machine entrance by the present invention, and sets up coil winding machine after hauling machine.
