Description

Izum se odnosi na materijal za traku za transportne i prijenosne trake, koji se u biti sastoji os netkanog materijala, veziva i učvršćivača. Iz DE 28 42 837 je već poznata prenosna traka koja se malo isteže, koje se malo istezanje postiže pomoću paralelnih tekstilnih pređa kao učvršćivača, koji imaju maksimalno istezanje od 20% pri 50% nominalnog opterećenja na kidanje. Kod takve prenosne trake su u biti paralelne tekstilne pređe spojene s najmanje jednim slojem iz nesređenih vlakana prošivanjem. Paralelne tekstilne pređe kao i sloj od nesređenih vlakana su obuhvaćene matricom od elastomerne polimerne smole koja ne sadrži stanice. Mješavina vlakana za netkanu tkaninu za prošivanje može se sastojati od sintetskih vlakana kao što su poliamidna, poliesterska, poliolefinska, akrilna vlakna i/ili prirodnih vlakana kao što je juta. Sloj nesređenih vlakana može se našiti na tekstilne pređe jednostrano ili obostrano.Tekstilne pređe koje se mogu upotrijebiti kao učvršćivači mogu biti poliesterske ili poliamidne pređe. The invention relates to the material for the belt for transport and transfer belts, which essentially consists of non-woven material, binders and stiffeners. From DE 28 42 837, a low stretch conveyor belt is already known, which low stretch is achieved by means of parallel textile yarns as stiffeners, which have a maximum stretch of 20% at 50% of the nominal breaking load. In such a conveyor belt, essentially parallel textile yarns are joined to at least one layer of untidy fibers by stitching. The parallel textile yarns as well as the layer of disordered fibers are covered by a matrix of elastomeric polymer resin that does not contain cells. The fiber blend for the nonwoven quilting fabric may consist of synthetic fibers such as polyamide, polyester, polyolefin, acrylic fibers and/or natural fibers such as jute. A layer of untidy fibers can be sewn onto textile yarns on one side or on both sides. Textile yarns that can be used as stiffeners can be polyester or polyamide yarns.

Poslije njene izrade se šivena netkana tkanina impregnira pomoću tečnog međuproizvoda, koji daje poslije sušenja i vulkaniziranja polimernu smolu bez stanica. Prvenstveno se za ovo primjenjuje disperzija nitril-butadien-kaučuka. Prenosne trake koje se sastoje iz takvog materijala imaju u usporedbi s uobičajenim tkaninama obloženim trakama manje zvučan hod i visoku čvrstoću na zasijecanje, ali ipak imaju ograničenu mogućnost primjene jer pređe ili tkanine primijenjene kao učvršćivači imaju u sebi naprezanja, koja se još pojačavaju postupkom prošivanja iglom. Ovim načinom prije svega kratke ili široke trake ne mogu se više opremiti, t.j. traka ispadne poslije nekoliko obrtaja. After its production, the sewn non-woven fabric is impregnated using a liquid intermediate product, which after drying and vulcanization gives a polymer resin without cells. Nitrile-butadiene-rubber dispersion is primarily used for this. Conveyor belts made of such material have, in comparison with conventional cloth-coated tapes, a less noisy movement and a high resistance to cutting, but still have a limited possibility of application because the yarns or fabrics used as stiffeners have stresses in them, which are further amplified by the needle stitching process. . First of all, short or wide strips can no longer be equipped with this method, i.e. the tape falls out after a few turns.

Otuda je zadatak izuma stvaranje materijala za transportnu i prijenosnu traku, koji također i kod postrojenja kod kojih se teško upravlja jamči besprijekorno ponašanje pri kretanju, pri bešumnom kretanju i visoku čvrstoću na zasijecanje. Hence, the task of the invention is to create a material for a transport and transfer belt, which also guarantees perfect movement behavior, noiseless movement and high shear strength even in difficult-to-manage plants.

Ovaj zadatak se prema izumu rješava stavljanjem predene, netkane tkanine kao učvršćivača. According to the invention, this task is solved by placing a spun, non-woven fabric as a stiffener.

Za ovu svrhu su pogodne predene, netkane tkanine bolje pričvršćene termički, mehanički i/ili pomoću veziva i imaju kako u uzdužnom tako i u poprečnom pravcu visoku čvrstoću pri nižem istezanju. Prikladni primjeri za polimere, iz kojih je izrađena predena netkana tkanina, su poliesteri i poliamidi. For this purpose, suitable spun, non-woven fabrics are better attached thermally, mechanically and/or by means of binders and have both longitudinal and transverse high strength with lower elongation. Suitable examples of the polymers from which the spun non-woven fabric is made are polyesters and polyamides.

Prigodne su isto tako i netkane tkanine od staklenih vlakana. Non-woven fabrics made of glass fibers are also suitable.

Ograničeno je stavljanje polimera, ako oni imaju visoke čvrstoće i niska istezanja, samo time, što njihova točka topljenja ne leži u blizini temperature, pri kojoj se termički pričvršćuje ili se poslije jednostranog ili obostranog prošivanja i impregriranja pomoću veziva suši. The use of polymers is limited, if they have high strength and low elongation, only because their melting point is not close to the temperature at which it is thermally attached or dried after one- or two-sided quilting and impregnation with a binder.

Tako je polipropilen manje pogodan, pošto njegovo talište leži u blizini temperature sušenja, pri kojoj se suši prošivena netkana tkanina impregnirana sa nitril-butadien-kaučukom. Predene netkane tkanine sastavljene kao nosilac čvrstoće imaju najpodesniju silu kidanja od najmanje 10 N/mm pri istezanju 1%. Thus, polypropylene is less suitable, since its melting point is close to the drying temperature at which stitched non-woven fabric impregnated with nitrile-butadiene-rubber is dried. Spun non-woven fabrics assembled as a strength carrier have an optimum tear force of at least 10 N/mm at 1% elongation.

Titar vlakna predene netkane tkanine leži najpodesnije kod 1 do 20 dtex-a, naročito kod 3 do 6 dtex-a. The fiber titer of the spun non-woven fabric is most suitable at 1 to 20 dtex, especially at 3 to 6 dtex.

Masa površine predene netkane tkanine iznosi 50 do 300 g/m2, prvenstveno 175 do 225 g/m2. Za dostizanje traženih vrijednosti čvrstoće na kidanje od najmanje 10 n/mm pri istezanju 1% može biti korisno da se umetnu dva ili više sloja predene netkane tkanine. Pri tom se može ušiti između pojedinačnih slojeva predene netkane tkanine mala količina nesređenih vlakana. Ovo se isto tako povoljno odražava na kasnije ponašanje kretanja trake. The surface mass of the spun non-woven fabric is 50 to 300 g/m2, preferably 175 to 225 g/m2. To achieve the required tear strength values of at least 10 n/mm at 1% elongation, it may be useful to insert two or more layers of spun nonwoven fabric. In doing so, a small amount of untidy fibers can be sewn between the individual layers of the spun non-woven fabric. This also has a favorable effect on the later behavior of the tape movement.

Pri izradi materijala netkane tkanine prošivaju se jedan ili više slojeva predene netkane tkanine obostrano sa netkanom tkanonom nesređenih vlakana, onda se mehanički pričvršćena tkanina impregnira pomoću rastvora veziva i zatim se pri temperaturi od 150°C suši i vulkanizira. When making non-woven fabric material, one or more layers of spun non-woven fabric are stitched on both sides with a non-woven fabric of unsorted fibers, then the mechanically attached fabric is impregnated with a binder solution and then dried and vulcanized at a temperature of 150°C.

Vezivna sredstva koja se pretpostavljaju su lateks nitril-butadien-kaučuk i/ili stirol-butadien-kaučuk. Kao vezivna sredstva mogu se staviti vodene i/ili u rastvaraču rastvorena veziva kao poliuretan, polivinil klorid, poliakrilat ili njihovi spojevi. Pri tome može iznositi odnos vlakno:vezivo prvenstveno 1:2 do 2:1, naročito se pretpostavlja 1:1 dijelova mase. The binders assumed are latex nitrile-butadiene-rubber and/or styrene-butadiene-rubber. Aqueous and/or solvent-dissolved binders such as polyurethane, polyvinyl chloride, polyacrylate or their compounds can be used as binders. In this case, the fiber:binder ratio can be primarily 1:2 to 2:1, especially 1:1 parts by mass is assumed.

Impregrirani i sušeni materijal netkane tkanine može se za poboljšanje površine, potom na jednoj ili obje strane izgladiti pomoću brusnog papira. The impregnated and dried material of the non-woven fabric can be smoothed on one or both sides using sandpaper to improve the surface.

Podesan materijal za traku, za izradu prijenosnih traka može biti debljine od 1,5 do 8 mm, i masu površine od 6.000 g/m2, pretpostavlja se 2.000 do 4.000 g/m2. Slike pokazuju u uzdužnom presjeku materijal za traku prema izumu. Traka (1) se sastoji od predene netkane tkanine (2) (ovdje nacrtane jednoslojno). Predena, netkana tkanina (2) je sa obe strane prošivena sa po slojem od nesređenih vlakana (3). Traka (1) (t.j. predena netkana tkanina (2) i obostrano s tim prošiveni slojevi nesređenih vlakana (3) ) su potpuno umetnuti u matricu od veziva. Suitable tape material for the production of transfer tapes can have a thickness of 1.5 to 8 mm, and a surface weight of 6,000 g/m2, 2,000 to 4,000 g/m2 is assumed. The figures show a longitudinal section of the tape material according to the invention. The strip (1) consists of a spun non-woven fabric (2) (here drawn as a single layer). The spun, non-woven fabric (2) is stitched on both sides with a layer of untidy fibers (3). The web (1) (i.e. the spun non-woven fabric (2) and the layers of unordered fibers (3) stitched thereon on both sides) are fully embedded in the binder matrix.

Izum se prikazuje slijedećim primjerima. The invention is illustrated by the following examples.

Primjer 1 Example 1

250 g/m2 poliesterskih vlakana, koje se sastoje iz 2 mas.-dijela 6,7 dtex-a (dužina sječenog vlakna 40 mm) 1 l mas.-dijela 17 dtex-a (dužina sječenog vlakna 60 mm) (800 pojedinačnih bodova po cm2) da se u velikoj mjeri ne događa oštećenje predene netkane tkanine. Osnovna netkana tkanina se potom impregnira sa 100 mas.-% lateksa nitril-butadien-kaučuk, kome su dodani 25mas.-% kalcijum karbonata kao punilac i 5 mas.-% sredstva za vulkaniziranje od sumpor i cink oksida, koagulira u infracrvenoj peći, ispira, odstrani voda, potom na 150°C suši i vulkanizira. 250 g/m2 polyester fibers, consisting of 2 parts by weight 6.7 dtex (cut fiber length 40 mm) 1 part by weight 17 dtex (cut fiber length 60 mm) (800 individual points per cm2) that damage to the spun nonwoven fabric does not occur to a large extent. The basic non-woven fabric is then impregnated with 100 wt.-% nitrile-butadiene-rubber latex, to which 25 wt.-% calcium carbonate as a filler and 5 wt.-% sulfur and zinc oxide vulcanizing agents were added, coagulated in an infrared oven, rinse, remove water, then dry at 150°C and vulcanize.

Zatim se materijal netkane tkanine pričvršćen vezivom obostrano izgladi brusnim papirom, finoće 120, tako da nastaje ravnomjerno glatka površina, debljine 5,5 mm i masa 3.500 g/m2. Proizvod ima silu kidanja od 10 N/mm pri istezanju 1 %. Then, the material of the non-woven fabric attached with a binder is smoothed on both sides with sandpaper, fineness 120, so that a uniformly smooth surface, 5.5 mm thick and 3,500 g/m2, is created. The product has a tearing force of 10 N/mm at 1% elongation.

Primjer 2 Example 2

Između dvije termički pričvršćene poliesterske netkane tkanine sa masom od po 200 g/m2 i titrom od 4,5 dtex-a ušiju se najprije 200 g/m2 poliesterska nesređena vlakna, koja se sastoje iz 2 mas.-dijela 6,7 dtex-a (dužina sječenja 40 mm) i 1 mas.-dijela 17 dtex-a (dužina sječenja 60 mm), sa 800 pojedinačnih bodova na cm2. Ovom spoju se u drugom stupnju prišiju obostrano po 800 g/m2 poliesterska vlakna iste mješavine, isto tako sa 800 pojedinačnih bodova po cm2. Dalja obrada se vršila kao u Primjeru 1. Gotov proizvod posjeduje silu kidanja od 14 N/mm pri istezanju 1 %. Between two thermally attached polyester non-woven fabrics with a weight of 200 g/m2 each and a titre of 4.5 dtex, 200 g/m2 polyester untidy fibers are sewn first, consisting of 2 parts by weight of 6.7 dtex (cutting length 40 mm) and 1 mass-part 17 dtex (cutting length 60 mm), with 800 individual points per cm2. In the second step, 800 g/m2 polyester fibers of the same mixture are sewn to this joint on both sides, also with 800 individual points per cm2. Further processing was carried out as in Example 1. The finished product has a tearing force of 14 N/mm at 1% elongation.
