Abstract
The invention relates to a high-strength nylon ribbon for tying up construction reinforcing steel bars. The nylon ribbon is prepared by the following steps: mixing PA66, an aramid fiber and a lubricating agent, casting the mixture in a preheated die, reacting at 80-90 DEG C for 10-30min, cooling the die and taking out a finished product; the ribbon is composed of a ribbon head and two ribbon strips, which are integrally formed, wherein a plurality of buckle teeth are uniformly distributed on the two ribbon strips respectively; fixed holes, in which the ribbon strips are clamped, formed on two sides, opposite to the two ribbon strips, of the ribbon head respectively; fastening teeth matched and fastened with the buckle teeth are arranged in the fixed holes; the fastening teeth are of straight-inclined structures, and the buckle teeth on the ribbon strips gradually become thicker and deeper from one end away from the ribbon head to one end close to the ribbon head; and the fastening teeth in the fixed holes gradually become smaller and shallower from the inserting port to an outlet. The nylon ribbon disclosed by the invention can be used for not only realizing simple and convenient operation so as to improve the working efficiency, but also guaranteeing the strength, the rigidity and the tying firmness.
Description
Technical field
The present invention relates to band manufacturing technology field, be specifically related to a kind of building iron and tie up and use high-strength nylon band.
Background technology
In the last thirty years, domestic construction industry is vigorously sent out and is opened, Highrise buildings, high-speed rail bridge, highway bridge is found everywhere, in the mixed earth cast engineering of various construction work, reinforcing mat to be absolutely necessary structural part as its skeleton, because reinforcing mat takes many reinforcing bars to combine, and a kind of spatial grid structure formed, so when making reinforcing mat, the colligation to the reinforcing bar of composition reinforcing mat carries out each other is often needed to fix.And mainly little wire binding is used, this mode utilizing wire binding, operating flexibility with being connected to the fixing of reinforcing mat, but inefficiency, steel wire corrosion-vulnerable is got rusty, and causes its intensity and stability reduction.
And in order to improve working efficiency during wiretie net, nylon cable tie has been used in part building, can significantly improve operation effect by nylon cable tie wiretie net, but general nylon cable tie still exists that strength and stiffness are poor, to tie up firmness not high, easily occurs slide fastener phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and both can have realized simple to operation, to increase work efficiency, proof strength, rigidity and the building iron of tying up firmness can tie up and use high-strength nylon band again.
Following technical scheme is present invention employs: a kind of building iron is tied up and used high-strength nylon band, is made up of the raw material of following weight part in order to reach foregoing invention object:
(1) PA66 100 parts;
(2) aramid fiber 10 ~ 30 parts;
(3) lubricant 0.5 ~ 2 part.
In order to obtain better invention effect, further setting is done to the present invention: described PA66 relative viscosity need control be 2.3 ~ 3.2, the weight percent of moisture need control below 0.15%, thus can ensure that PA66, aramid fiber, lubricant are better disperseed in the process of mixing, make the mobility of processing better, be conducive to the nylon cable tie of obtained better intensity.
The further setting of the present invention, described lubricant can be the mixture of EBS, silicone a kind of or two kinds, by EBS, silicone are conducive to as lubricant the processing fluidity improving PA66 material further, to reduce frictional coefficient, improve its dispersion effect simultaneously.
The invention still further relates to a kind of building iron described above and tie up the preparation method using high-strength nylon band, comprise the following steps: first PA66, aramid fiber, lubricant are got the raw materials ready by the raw material of certainweight number, again the PA66 got ready, aramid fiber, lubricant are joined in reactor, 0.5-1 hour is stirred at 60-80 DEG C, finally the material mixed is poured in preheated mould, control in 80-90 DEG C of situation in temperature, reaction 10-30 minute, can take out product after cooling.
The further setting of the present invention: described nylon cable tie by an integrated tie head be connected to tie head and become two band bars of vertical configuration to form, two described band bars are evenly equipped with some snapper teeth respectively, both sides contrary with two band bars in described tie head are respectively equipped with the fixed orifices snapped in for band bar, be provided with in described fixed orifices to engage with described snapper teeth adaptation and fasten tooth, described fastening tooth is set to straight inclined structure.Such band bar direction of insertion is inclined-plane, can reduce resistance when band bar inserts, and band bar to insert be in the other direction vertical surface, thus the skid resistance very large to the generation of band bar, even if band has very large drawing force, ties up firmness with what strengthen band.
The further setting of the present invention: the snapper teeth size on described band bar deepens by one end of the extremely close tie head in the one end away from tie head is progressively thicker, fastens teeth size and shoaled to exporting progressively to diminish by insert port in described fixed orifices.Thus be conducive to the drawing force improving band further, tie up firmness with what improve band further.
Beneficial effect of the present invention is:
1, by being added with aramid fiber in PA66 material, the nylon cable tie obtained is made to have higher intensity and rigidity, the high band that makes of intensity has very high tension pull out force, intensity is tied up with what strengthen band, and the high snapper teeth on band and the fastening tooth of making of rigidity is out of shape little, thus effectively can reduce slide fastener phenomenon, ensure that the town of band buckles soundness and security, meanwhile, because nylon material molecular chain has a lot of polarity gene can have excellent cohesiveness between cement.
2, by the structure design of nylon cable tie of the present invention, can not only increase work efficiency, and be conducive to the drawing force improving band further, tie up firmness with what improve band further, thus can be good at avoiding nylon cable tie to tie up the rear phenomenon occurring slide fastener.
figure of description
Fig. 1 is the structural representation that a kind of building iron of the present invention ties up with high-strength nylon band;
Fig. 2 is the B-B sectional view of Fig. 1 in the present invention.
Embodiment
Be explained in detail below in conjunction with the specific embodiment of the present invention, can be easier to make advantages and features of the invention be those skilled in the art will recognize that thus defining of more clear and definite is made to protection scope of the present invention.
As shown in Figure 1 and Figure 2, a kind of building iron of the present invention is tied up and is used high-strength nylon band, by an integrated tie head 1 be connected to tie head 1 and become two band bars 2 of vertical configuration to form, its two bands bar 2 is evenly equipped with some snapper teeth 21 respectively, both sides contrary with two band bars 2 in tie head 1 are respectively equipped with the fixed orifices 3 snapped in for band bar 2, be provided with in its fixed orifices 3 and engage fasten tooth 31 with snapper teeth 21 adaptation, and fastening tooth 31 is set to straight inclined structure.When like this band bar 2 being inserted fixed orifices 3, its direction is inclined-plane, resistance when band bar 2 inserts can be reduced, and band bar 2 insertion is vertical surface in the other direction, thus very large skid resistance is produced to band bar 2, even if band has very large drawing force, firmness is tied up with what strengthen band, wherein, snapper teeth 21 size on band bar 2 deepens by one end of the extremely close tie head 1 in the one end away from tie head 1 is progressively thicker, and fastening tooth 31 size is shoaled to exporting progressively to diminish by insert port in fixed orifices 3, thus be conducive to the drawing force improving band further, firmness is tied up with what improve band further.
