No. 1,922,441, 2,300,368, 2,426,654, 2,426,657, U.S. Pat. 803 069, 3 814 592, Jap., 6, 57, 603, 10, 80 023 778, U.S. Pat. No. 1,522,148), thermoplastic polyethers (NSR Pat. 6, 2,426,656, French Pat. No. 2 275 417) and polycarbonates (NSR Pat. No. 2426 655).
Ako vazbové prostriedky sa používajú r5zne zlúčeniny, z ktorých majú zatial1 naj-vačéi prakticky význam rázné substituované silany, hlavně aminosilany ako 3-aminopropyl-trietoxysilan a epoxyeilany ako 3-glycidoxypropyltrimetoxyeilan. Rozšířené Je aj použi-tie aduktov epoxidov s aminosiíanmi (USA pat. δ. 3 814 592, brit. pat, δ. 1 522 148,δ 3.. aut. osv. δ. 255 390) a kombinácie kationických silanov s polyaminosilanmi (USA pat.δ. 4 382 991). široká peleta používaných vazbových prostriedkov je vyvolaná snahou nlelen zlepšitv čo najvačšej miere mechanické vlastnosti sklsvláknitých kompozitov, ale aj regulovatcelý rad textilných vlastnosti skleněných vlákien so snahou připravil lubrikácie, ktorésa vyznaéujú vysokou tepelnou a mechanickou stabilitou a minimálnou toxicitou pre pra-covnikov prichádzajúcich do styku s lubrikáciou a upraveným skleněným vláknem.The binding agents used are various compounds, of which, in the meantime, vigorously substituted silanes, especially aminosilanes such as 3-aminopropyl-triethoxysilane and epoxyeilanes such as 3-glycidoxypropyltrimethoxyeilane, are of importance. The use of epoxy adducts with aminosulfates is also widespread (U.S. Pat. No. 3,814,592, U.S. Pat. No. 5,252,148, δ3. Aut. Illumination δ. 255,390) and combinations of cationic silanes with polyaminosilanes ( U.S. Pat. No. 4,382,991). the wide pellet of bonding agents used is due to the effort to improve the mechanical properties of the fiberglass composites as well as to regulate a wide range of glass fiber textile properties with the aim of providing lubrication that exhibits high thermal and mechanical stability and minimal toxicity to lubricant contacters and treated glass fiber.
Pre polyuretanové Je charakteristická, δΐ už neiónové, katianaktivne alebo aniano-aktívne, připravené různými postupmi (NSR pat. δ. 1 770 068, 1 913 271, USA pat. δ. 3 245 961 ča. aut. osv. δ. 167 888), že nimi upravené vlákna majú makký charakter, δο ichpreduréujú ako zvlášt výhodné k úpravě skleněných vlákien vhodných k výrobě rohoží,tkanin a nekoneéného vlákna vo formě rovingov. V případe výroby sekaných vlákien, kto-rých použitie k výrobě vystužených termoplastov je zatiaí najrozširensjšie, je tentoproblém zvy6ajne riešsný tak, že sa zvyšuje koncentrácia lubrikócii, δο sa prejavuje ne-gativné na zhoršenie pracovných podmisnok, zvýšenis ekonomických nákladov a zhoršenisekologických opatřeni pri riešeni lubrikaéných odpadov.For polyurethane It is characteristic, δΐ already non-ionic, catianactively or aniano-active, prepared by various procedures (NSR Pat. No. 1 770 068, 1 913 271, US Pat. No. 3 245 961 Act. ) that their treated fibers are of a non-intrusive nature, δο they predetermine them as being particularly advantageous for the treatment of glass fibers suitable for the manufacture of mats, fabrics and non-fibers in the form of rovings. In the case of the production of chopped fibers, the use of which is still the most widely used for the production of reinforced thermoplastics, it is particularly desirable to increase the concentration of the lubricant, δο have an adverse effect on the deterioration of the working conditions, increase the economic cost and impairment of the lubrication waste.
Zistili sme, že uvedené problémy je možné úéinne riešit za použitia lubrikácii pó-dia vynálezu.We have found that these problems can be solved efficiently by using the lubrication of the invention.
Vynález popisuje polyuretanové lubrikácie na úpravu skleněných vlákien. Podstatariššenia spočiva v tom, že sú zložené z 0,5 až 7 % hmotnosti sušiny polyuretanovej emul-zie, 0,05 až 1 % hmotnosti maleinsilanov obecného vzorca HOOCCHeCHCONH (C2H4NR2)^Ηθδΐ (0Rx) 3, kde představuje R^ metyl alebo etyl, Rg je atom vodika alebo zbytok o štruktúre -COCHaCHCOOK, x je celé šišlo O alebo 1, 0,01 až 1 % hmotnosti kationického mazadla, ako ami-noamidy, imidazoliny a kvartenizované dusikaté tenzidy, a zbytku do 100 % hmotnosti vo-dy. Textilnó vlastnosti vlákien a stabilitu lubrikácie je možné v případe potřeby, hlav-ně pódia použitého technologického zariadenia, regulovat pridavkom 0,001 až 3 % hmotnos-ti aspoň jednej přísady zo skupiny regulátorov pH, antistatik, mazladsl, zmééadiel, vaz-bových prostriedkov ako organické kyseliny a zásady, chlorid litny, polyetylénglykoly,neiónovétenzidy, aminosilany a epoxyeilany. V závislosti od aplikašného použitia vlákienje možné ich polaritu měnit pódia potřeby pridavkom 0,5 až 4,5 % hmotnosti sušiny emul-zie polymérov na báze vinylických a/alsbo olefinických monomérov ako vinylacetát, styrén,etylén, propylén, kyselina akrylová δί metakrylová a ich estery.The present invention provides polyurethane lubricants for treating glass fibers. In essence, they consist of 0.5 to 7% by weight of a dry polyurethane emulsion, 0.05 to 1% by weight of maleinsilanes of the general formula HOOCCHeCHCONH (C2H4NR2) ^ Ηθδΐ (ORx) 3, wherein R ^ is methyl or ethyl , R 8 is a hydrogen atom or a moiety having the structure -COCH aCHCOOK, x is an integer of 0 or 1, 0.01 to 1% by weight of a cationic lubricant, such as amine amides, imidazolines and quaternized nitrate surfactants, and a residue of up to 100% by weight of water . The textile properties of the fibers and the stability of the lubrication can be controlled by adding 0.001 to 3% by weight of at least one additive from the group of pH regulators, antistatic agents, lubricants, diluents, binders such as organic acids, if necessary, in particular the process equipment used. and bases, lithium chloride, polyethylene glycols, nonionic surfactants, aminosilanes and epoxyeilanes. Depending on the application of the fibers, their polarity can be varied according to the need by adding 0.5 to 4.5% by weight of dry matter emulsion of polymers based on vinyl and / or olefinic monomers such as vinyl acetate, styrene, ethylene, propylene, acrylic acid and methacrylic acid and their esters.

It is characterized by high storage and mechanical stability, δο allows you to prepare your quantity without any negative impact on its quality. It is practically impossible to use 271 995 B1 2
Javujé problémy s vznikom kontaktných dermatóz, či už:pri manipulácii s lubrikáciou ale-bo jej za použitia upravených skleněných vlákien. Upravené skleněné vlákna majé v dósled-sku přítomnosti maleinsilanov vysoké odolnost voči abrázii, dobré sekateínost a integri-tu skleněného prameňa. Tento efekt umožňuje vyrábat sekané skleněné vlákna za použitialubrikácie s prakticky íúbovoíným druhom polyuretanovej disperzie, čo sa významné preja-vuje pri znižovaní výrobných nákladov. Lubrikáciami upravené skleněné vlákna sú zvláštvhodné ako výstuž termoplastických polyamidov, polyesterov, polykarbonátov a pod.They have problems with the formation of contact dermatoses, either: when handling lubrication or using modified glass fibers. The treated glass fibers have a high resistance to abrasion, good glass strand integrity and integrity in the presence of maleinsilane. This effect makes it possible to produce chopped glass fibers using a lining with a virtually any type of polyurethane dispersion, which is significant in reducing production costs. Lubricated glass fibers are particularly suitable as reinforcement of thermoplastic polyamides, polyesters, polycarbonates and the like.
Maleinsllany pódia vynálezu je možné přidávat priamo do vody pri priprave lubrikáciiči už v koncentrovanej formě alebo vo formě roztokov. Okrem týchto možnosti je ich možnépřipravovat pri priprave lubrikácie reakciou příslušných aminosilanov ako 3-aminopropyl-trietoxysilan, 3-(2-aminoetyl)aminopropyltrimetoxysilan s maleinanhydridom.Adiciu je mož-né uskutočňovaf v rozných organických rozpéštadla^h, hlavně alkoholech ako etylalkohol. V případe okamžitého použitia k výrobě lubrikácii srna zistili, že adiciu maleinanhydridus aminosilanom je možné uskutečňovat priamo vo vodě z dovodu, že přednostně před hydro-lýzou maleinanhydridu beži jeho reakcia s příslušným aminosilanom na amid, čo bolo doká-zané spektrálnou analýzou a určením obsahu karboxylových skupin. Ostatné suroviny pódiavynálezu sé známe· a komerčné dostupné. Z polyuretanových disperzi! však je najvýhodnejšiepoužitie kationického charakteru, pre svoju zvýšené afinitu k anionickému povrchu skleně-ných vlákien.The maleinsilane of the invention may be added directly to the water when prepared by the lubricants already in concentrated form or in the form of solutions. In addition to these possibilities, they can be prepared in the preparation of lubrication by reaction of the corresponding aminosilanes such as 3-aminopropyltriethoxysilane, 3- (2-aminoethyl) aminopropyltrimethoxysilane with maleic anhydride. The adicion can be carried out in various organic solvents, especially alcohols such as ethyl alcohol. In the case of immediate use for the production of doe lubrication, they found that the addition of maleic anhydride by aminosilane can be carried out directly in the water, since its reaction with the corresponding aminosilane to the amide is preferred to hydrolysis of the maleic anhydride, as demonstrated by spectral analysis and determination of carboxylic acid content. groups. Other raw materials of the invention are known and commercially available. From polyurethane dispersions! however, it is most preferred to use a cationic character because of its increased affinity for the anionic surface of glass fibers.
