Description
4é6 456 10 15 20 25 30 35 2 stenar. Denna kända åtgärd innebär emellertid en väsent- lig inskränkning av i praktiken användbara smältlim. 4é6 456 10 15 20 25 30 35 2 stones. However, this known measure entails a significant restriction of hot-melt adhesives which are useful in practice.
Uppfinningen har därför till ändamål att utpeka en möjlighet till att inom krymptekniken kunna använda godtyckligt förnätningsbara smältlim för säker för- bindning. Ändamålet uppnås enligt uppfinningen därigenom, att vid en krympartikel med smältlimskikt åtminstone ett av de mot varandra anliggande materialskikten är förnätat genom inverkan av fukt efter påympning av organosilanföreningar. Denna åtgärd säkerställer en enkel framställning också vid hålkroppar, såsom slangar och krympartiklar med godtycklig form. Doseringen från ringa förnätning till höga förnätningsgrader kan lätt genomföras, styrningen av förnätningsmekanismen möjlig- gör inställning av t ex limmets viskositet på godtycklig nivå.The object of the invention is therefore to point out an opportunity to be able to use arbitrarily crosslinkable hot melt adhesives in the shrinkage technique for a secure connection. The object is achieved according to the invention in that in the case of a shrink particle with hot-melt adhesive layer at least one of the adjacent material layers is crosslinked by the action of moisture after inoculation of organosilane compounds. This measure ensures a simple manufacture even with hollow bodies, such as hoses and shrink particles of any shape. The dosing from low crosslinking to high degrees of crosslinking can easily be carried out, the control of the crosslinking mechanism makes it possible to set, for example, the viscosity of the adhesive at an arbitrary level.
Krympkroppens material självt kan förnätas genom inverkan av fukt. För det fall att också det påförda limskiktet är fuktförnätningsbart efter påympning av silaner väljer man vid vidareutveckling av uppfinnings- tanken med fördel olika förnätningsgrader för de an- gränsande skikten. Materialet i krympartikeln kan också vara förnätningsbart peroxidiskt eller genom strålning, medan smältlimmet är förnätningsbart genom inverkan av fukt, och detta alltefter mängden av de påympade silanföreningarna, med olika förnätningsgrader. På detta sätt kan via en bestämd förnätningsgrad eller påbörjad förnätningsgrad inställas en godtycklig trög- flytning (viskositet) hos limmet och limmet därigenom optimalt anpassas till de mest olika uppgifterna.The material of the shrink body itself can be crosslinked by the action of moisture. In the event that the applied adhesive layer is also moisture-crosslinkable after inoculation of silanes, different degrees of crosslinking for the adjacent layers are advantageously selected for further development of the inventive tank. The material in the shrink particle can also be crosslinkable peroxidically or by radiation, while the hot melt adhesive is crosslinkable by the action of moisture, and this according to the amount of the silane compounds injected, with different degrees of crosslinking. In this way, via a certain degree of crosslinking or initiated degree of crosslinking, an arbitrary viscous flow (viscosity) of the adhesive can be set and the adhesive is thereby optimally adapted to the most different tasks.
Enligt en speciellt fördelaktig utföringsform av uppfinningen är materialet i krympartikeln, dvs bandet, slangen eller manteln, förnätningsbart genom fuktinver- kan, medan smältlimmet är förnätningsbart peroxidiskt.According to a particularly advantageous embodiment of the invention, the material in the shrink particle, i.e. the strip, the hose or the jacket, is crosslinkable by the action of moisture, while the hot-melt adhesive is crosslinkable peroxidically.
Det är då nämligen möjligt att genom en senare tillsats av förnätningsmedlet låta förnätningen göra sig gällan- 10 15 20 25 30 35 466 436 3 de först då, när krympartikeln genom temperaturinverkan underkastas returkrympningen. Därigenom uppnås att ma- terialet i limmet eller limmet får ett viskositetssprång och skärhållfasthetsökning först i slutet av monte- ringen, så att fram till denna tidpunkt krympartikelns expandering samt monteringen icke hindras av ett allt- för trögflytande lim.Namely, it is then possible, by a later addition of the crosslinking agent, to allow the crosslinking to take effect only when the shrink particle is subjected to the return shrinkage by the effect of temperature. Thereby it is achieved that the material in the glue or glue gets a viscosity jump and cutting strength increase only at the end of the assembly, so that until this time the expansion of the shrink particle and the assembly is not hindered by an excessively viscous glue.
Smältlimmet kan anbringas på krympartikeln på godtyckligt sätt. Det är lämpligt att extrudera eller spruta den krympbenägna formkroppen och limskiktet tillsammans. Om materialet i formkroppen består av ett sådant material på vilket silanföreningar är påympade, förnätas genom påföljande inverkan av fukt materialet i krympkroppen utan att limmets egenskaper förändras.The hot melt adhesive can be applied to the shrink particle in any manner. It is convenient to extrude or spray the shrinkable mold body and the adhesive layer together. If the material in the shaped body consists of such a material on which silane compounds are grafted, the material in the shrink body is crosslinked by the subsequent action of moisture without changing the properties of the adhesive.
Vid påföljande utvidgning t ex av en krympslang för senare returkrympning genom temperaturinverkan kan limmet, vars flytförmåga dittills icke hindrats av en förnätning, följa med i töjningsrörelserna av slangen, utan att man får en släppning. Först när limskiktet på den expanderade slangen, eller det sträckta bandet eller den expanderade manteln eller manschetten an- rikas med förnätningsmedlet för förnätningssyfte, får limmet i början av returkrympningen en viskositets- ökning under inflytandet av krymptemperaturer, vilken viskositetsökning medför skärhållfasthet hos limskik- tet, något som ju krävs av dylika krympförband.Upon subsequent expansion, for example of a shrink tubing for later return shrinkage by the effect of temperature, the adhesive, the buoyancy of which has hitherto not been hindered by a crosslinking, can follow the stretching movements of the hose, without being released. Only when the adhesive layer on the expanded hose, or the stretched strip or the expanded jacket or cuff is enriched with the crosslinking agent for crosslinking purpose, does the adhesive at the beginning of the return shrinkage increase in viscosity under the influence of shrinkage temperatures, which viscosity increase in adhesive strength, something that is required of such shrink joints.
I detta sammanhang har ett sådant sätt visat sig speciellt fördelaktigt vid vilket silanföreningen påympas materialet i formkroppen, det ympade materia- let därpå formas till formkropp och överdrages med smältlim. Materialet i formkroppen förnätas sedan genom inverkan av fukt och förnätningsmedlet för smältlimmet införes i smältlimskiktet genom diffusion.In this context, such a method has proved particularly advantageous in which the silane compound is grafted onto the material in the molded body, the grafted material is then formed into a molded body and coated with hot melt adhesive. The material in the shaped body is then crosslinked by the action of moisture and the crosslinking agent for the hot melt adhesive is introduced into the hot melt adhesive layer by diffusion.
För uppfinningens syften kan godtyckliga material användas som bas för smältlimmet, t ex eten-vinyl- acetat-sampolymerer, akrylatpolymerer, eller material på bas av polyamider, sampolyamider, termoplastiska gummín samt polyester eller liknande. 466 436 4 Dessa limmaterial kan också vara skumbara, för att ge en viss elasticitet åt förbandet mellan en krympdetalj och ett underlag.For the purposes of the invention, any materials may be used as a base for the hot melt adhesive, for example ethylene-vinyl acetate copolymers, acrylate polymers, or materials based on polyamides, copolyamides, thermoplastic rubbers and polyester or the like. 466 436 4 These adhesive materials can also be foamable, to give a certain elasticity to the connection between a shrinkage detail and a substrate.
Som förnätningsmedel kan användas de sedvanliga' 5 peroxiderna, såsom dikumylperoxid, kumyl-tert.butyl- peroxid, 2,5-dimetyl-2,5-di-(tert.butyl)-peroxihexan eller andra radikalinitiatorer, såsom 1,10-dekan-bis sulfonazid eller p-kinondioxim.As the crosslinking agent, the usual peroxides such as dicumyl peroxide, cumyl-tert-butyl peroxide, 2,5-dimethyl-2,5-di- (tert-butyl) -peroxyhexane or other radical initiators, such as 1,10-decane, can be used. -is sulfonazide or p-quinone dioxime.
