Abstract
Description
Vynález sa týká cyklohexenylsllanu vhodného ako promotoradhezie na úpravu plniv pre výstuž plastov.BACKGROUND OF THE INVENTION The present invention relates to cyclohexenylslanine useful as a promoter for the treatment of fillers for plastic reinforcement.
Za účelora zlepšenia adhezie plastov k roznym anorganickým substrátom, či ve formě vlákien, guličiek, tkanin, drtě a pod. sa uskutečňuje úprava fázového rozhrania róznymi vazbovými prostriedkami, tiež nazývanými promotory adhezie. Priemyselne je najpoužívanejší sposob aplikovat vazbové prostriedky z vodných systémov, hlavně s dovodu, že použitie organických rozpúštadiel je obmedzené, či už pre ich toxicitu, horlavosť a v neposlednom řade aj z ekonomických příčin.In order to improve the adhesion of plastics to various inorganic substrates or in the form of fibers, beads, fabrics, pulp and the like. the phase interface is adjusted by different binding means, also called adhesion promoters. In industrial terms, the most widely used method is to apply binding agents from aqueous systems, mainly because the use of organic solvents is limited, either because of their toxicity, flammability and, last but not least, for economic reasons.
Cyklohexenylsilany sú známe a aplikovat do vodných kompozici! je ich možné buď vo formě emulzií alebo solí v připadne dusíkatých derivátov. Nie je známy spósob ani deriváty, ktoré sa dajú aplikovat do vodných systémov jednoduchým rozpuštěním vo vodě.Cyclohexenylsilanes are known and applied to aqueous compositions! they are possible either in the form of emulsions or salts or nitrogen derivatives. There is no known method or derivatives which can be applied to aqueous systems by simple dissolution in water.
Zistili sme, že tieto problémy sa odstránxe pri použití derivátu cyklohexenylsllanu podía vynálezu.We have found that these problems are eliminated by using the cyclohexenylsilane derivative according to the invention.
Vynález popisuje (3-cyklohexenyletyl) tris (2-aminoetoxy) silan sumárneho vzorca C^HjiQ-jN-jSí a štruktúrneho vzorca IThe present invention provides (3-cyclohexenylethyl) tris (2-aminoethoxy) silane of the general formula C ^HjiQQ-jNN j a and structural formula I
-CCff2)2 - si(oc2H4Nír2)3 ftí a jeho adičné s kyselinou mravčou a octovou soli.-C ( c ) 2 ) 2 -si (oc 2 H 4 Ni 2 ) 3 is 3 and its addition with formic acid and acetic salts.
Přípravu je možné uskutočniť pósobením 2-aminoetanolu na cyklohexenyletyltrialkoxysilany za zvýšenej teploty a uvolnenia příslušného alkoholu. V případě potřeby je ich možné neutralizáciou kyselinou mravčou a octovou previest na příslušné soli so zníženou až neutrálnou bazicitou.The preparation can be carried out by reacting 2-aminoethanol to cyclohexenylethyltrialkoxysilanes at elevated temperature and liberating the corresponding alcohol. If necessary, they can be converted to the corresponding salts with reduced to neutral basicity by neutralization with formic acid and acetic acid.
Vynález je ďalej objasněný formou příkladu.The invention is further illustrated by way of example.
PříkladExample
Do reakčenj banky opatrenej chladičom, miešadlom a teplomerom sa předložilo 100 g cyklohexenyletyltrietoxysilanu a 67,3 g 2-aminoetanolu. Násada za miešania vyhriala na 150 °C kedy sa začal uvolňovat etylalkohol. Reakcia sa nechala prebiehat až ďo uvolnenia teoretického množstva alkoholu, pričom teplota vystúpila až na 190 °C. Připravený silan má mernú hmotnost 1 076,6 kg . m-^ mPa . s pri 20 °C a index lomu pri 20 °C je 1,4806. Neutralizáciu je možné uskutečňovat jednoduchým přidáním silanu do vody s příslušnou kyselinou. Podlá potřeby je ju možné uskutočňovat v molárnom pomere silan : kyselina, rovnajúcom sa 1 : 1 až 3, čím sa pripravia roztoky soli neobmedzene miešatelné s vodou.100 g of cyclohexenylethyltriethoxysilane and 67.3 g of 2-aminoethanol were charged to a reaction flask equipped with a condenser, stirrer and thermometer. The batch was heated to 150 ° C with stirring when ethyl alcohol began to be released. The reaction was allowed to proceed until the theoretical amount of alcohol was released, the temperature rising to 190 ° C. The prepared silane has a specific gravity of 1076.6 kg. m - 1 mPa. s at 20 ° C and the refractive index at 20 ° C is 1.4806. Neutralization can be accomplished by simply adding silane to water with the appropriate acid. If desired, it can be carried out in a silane: acid molar ratio of 1: 1 to 3 to prepare salt solutions which are freely miscible with water.
