Description
Technical field
The present invention relates to twisted steel commonly used in a kind of civil engineering, particularly a kind of composite material twisted steel that can replace the reinforcing bar use belongs to field of constructional engineering material.
Technical background
Twisted steel is a reinforcing material commonly used in the civil engineering, is mainly used in support, the reinforcing of scaffold and steel concrete reinforcement material.Traditional reinforcing bar is because from great, the labor intensive material resources, and not corrosion-resistant again, especially the reinforced concrete structure in weather cold district and coastal area is subject to salt erosion harm, and the domestic for this reason twisted steel of having developed with Composite Preparation substitutes reinforcing bar.Present existing composite material twisted steel moulding process roughly has two classes, pultrusion-mold pressing type and pultrusion-winding-type, basically all be to utilize the mode machining screw muscle that on the drawing and extruding bar of moulding, carries out back processing and form screw thread, this twisted steel can improve itself and concrete bond and anchor property, and can improve the brittle failure of material.But, the twisted steel that adopts above-mentioned two kinds of processes is through manufacturing procedure processing later, promptly on the drawing and extruding bar of moulding, carry out the processing of twisted steel again, drawing and extruding bar forms a factory interface with processing part thereafter, in practice of construction, this interface still influences the bonding anchoring property of this twisted steel to a great extent, can not reach the construction requirement of its steel concrete, again because of its complex procedures, can't implement to promote simultaneously.
Summary of the invention
At the defective that exists in the above-mentioned prior art, the object of the present invention is to provide a kind of light weight, composite material twisted steel that bond and anchor property is good and preparation method thereof.
For achieving the above object, the present invention has adopted following technical scheme: a kind of composite material twisted steel, form by polyester glue and glass fiber mixing pultrusion, and the ratio of weight and number of described polyester glue and described glass fiber is 30～40: 60～70.
Described polyester glue is made up of polyester, release agent, methyl ethyl ketone peroxide basically, and its parts by weight proportioning is: 100 parts of polyester, 0.4～0.8 part of remover, 1.8～2.2 parts of methyl ethyl ketone peroxides.
Described polyester is the metaphenylene resin, and described glass fiber is an alkali-free glass fibre.
For achieving the above object, the present invention provides a kind of preparation method of composite material twisted steel simultaneously, and its characteristics are: it comprises following operating procedure:
1) impregnation of fibers immerses described glass fiber in the described polyester glue and to soak into fully, and the serviceability temperature of its polyester glue is 15-35 ℃, and dip time is 20-30 second;
2) step 1) being flooded the glass fiber of polyester glue, under draw, is boundling through the yarn passing hole pultrusion on the preformed template, described pultrusion speed be 0.2-0.4 rice/minute;
3) in step 2) the boundling surface longitudinal of moulding twines one deck fortifying fibre, and described fortifying fibre is sheathed on the wind, and the winding angle of its fortifying fibre is directly proportional with described speed of wrap;
4) step 3) is had the boundling that twines fiber, introduce hot setting in the mould, its solidification temperature is 125～175 ℃, and described boundling and its winding fiber curing molding are one;
5) boundling that solidifies depanning through step 4) twines device by separating of a band Scroll and separates and twine, with the winding fiber on its boundling and this boundling sur-face peeling, described winding fiber has regular screw-shaped finished product through separating the Scroll rolling that twines on the device in the formation of boundling surface.
Above-mentioned steps 2) described preformed template is at least 2, and wherein adjacent with a step 1) side is that a porous is crossed the yarn template; A side adjacent with step 3) is that a single hole is crossed the yarn template, and porous is crossed the center of yarn template and the centre bore relative positioning setting that single hole is crossed the yarn template.
Above-mentioned steps 3) described fortifying fibre is glass fiber or metallic fiber, and its metallic fiber is iron wire or copper cash.
Above-mentioned steps 3) described dies cavity length is 1-1.5m.
Above-mentioned steps 3) described wind and step 5) described separate to twine be separately installed with drive motors on the device, two drive motors are with fast anti-phase setting, its motor speed is 300-400 rev/min.
Preparation method of the present invention be utilize one successively by creel, steeping vat, preformed frock, twine the moulding extruding equipment that frock and the draw-gear that has drive motors combine, by the glass fiber of putting on the draw-gear traction creel, behind impregnation, enter the pultrusion of preformed frock and become boundling, through twining the composite material twisted steel of frock, the serviceability temperature of its polyester glue is 15-35 ℃ to boundling again;
Among the above-mentioned preparation method, winding angle can be adjusted by pultrusion speed and speed of wrap, the size of the angle of thread that can design its product according to the use and the performance requirement of twisted steel.
Adopt the composite material twisted steel of technical solution of the present invention preparation, have following beneficial effect:
The present invention has adopted whole preformed frock, and mould, preformed template center are accurately located, and is as the criterion by mould, preforming mould Board position, regulate wind and separate and twine the Unit Installation position, control the pultrusion speed and the speed of wrap of its glass fiber and adjust winding angle, the product of preparing, its screw thread is by global formation, removed back manufacturing procedure from, the production efficiency height, constant product quality also has stronger tensile strength simultaneously, anchored force is big, lightweight advantage; In the environment of seriously corroded, anti-corrosion capability surpasses metal threaded muscle, and can substitute reinforcing bar fully and use in building operations; Composite material twisted steel of the present invention is compared with metal threaded muscle, and its application life can be above three times.
