Abstract
The invention relates to a method and a device for producing reactive adhesives having at least two components, for example adhesives with moistureactivated cross-linking. According to said method at least one non-reactive adhesive component present in solid form, for example a granulate (G), or liquid form (F) and at least one reactive adhesive component present in the form of a solid, for example a granulate (G), or a liquid (F), are used. The two adhesive components are heated by pressure and friction in an endless screw in a specific proportion and mixed to produce the liquid reactive adhesive (K). The liquid reactive adhesive (K) is then applied directly to the area of application (use).
Description
~O 99/51411 PCT/E899/01232 METHOD AND DEVICE FOR PRODUCING TWO-COMPONENT REACTIVE
ADHESIVES
The invention relates to a method of producing at least two-component reactive adhesives, and a device that is subsequently integrated for processing the adhesive, for example a moisture-activated adhesive.
It is known in practice to heat and mix reactive adhesives comprising two or more components, thereby bringing them to a liquid mass, then package them gas-tight in a container, so as to preclude any air humidity;
the vacuum-packed reactive adhesive is then cooled, so it can be stored and transported in solidified form in the container. The desired processing is performed in known pre-melting devices, in which the adhesive is re--melted and then used for the application.
Disadvantages of this process are the relatively-high production costs, possible damage during the transport of the containers carrying the reactive adhesive, and the threat to the durability of the reactive adhesive due to leaks in the packaging over lengthy transport or storage periods. After the container is opened, the surface of the reactive adhesive reacts, and if the adhesive remains exposed for a long period of time, it becomes unusable.
This results in the return of the reactive adhesive, CONH'IR~1TION COpY
which, of course, incurs costs. Reactive adhesive that cannot be processed in its entirety out of a vessel and remains there becomes unusable, The period of durability begins practically at the end of the production process of the reactive adhesive:
this is critical for the optimum use of the reactive adhesive. Tn moisture-activated cross-linking adhesives, the chemical cross-linking reaction is triggered by air humidity, but also by the continuous effect of the temperature during the pre-melting and melting phase until the application.
It is an object of the invention to create a method with which a reactive adhesive is created in a single wozk step from separate components that have an unlimited shelf life, with a processing/application step following immediately afterward, and with which wasted adhesive, and thus additional costs, are avoided.
ACCOrding to the invention, this object is accomplished by the characterizing featurPS of claim 1;
the further method claims describe advantageous modifications of the solution to the object.
A further object lies in the creation of a simple, inexpensively-constructed, economically--operating device, with which ready-to-use reactive adhesives can be produced for the respective application without intermediate - 2 - CONFIRD~IITION COP?
i10 99/51411 PCT/EP99/01232 stations and ~,ritermediate storage.
The device features of claim 6, and advantageous modifications in the other device claims, accomplish this object_ The components of the reactive adhesive are stored separately to prevent premature contact and ensure an unlimited durability and shelf life of the components.
Consequently, the production methods are far s_mpler than before with respect to the individual components.
The adhesive comprises at least one propozticn of the non-reactive component(s), such as functionalized polymers and resin mixtures or others, and at least a second proportion comprising the xeactive component, such as polyisocynates and others.
The two or more Components of the adhesive to be produced ate placed, in solid or liquid form, into an extruder, with at least one component being metered corresponding to the adhesive mix~,ng ratio. The two or more components are mixed in a particular ratio to ons another, which is determined by their chemical structure and the later intended application of the adhesive. The supplied adhesive components are placed into tile extruder and heated through friction and pressure. The friction and pressure suffice to heat the adhesive. The adhesive can be subjected to an additional heating later, when the - 3 - CON~'IRMATZON COPY
WO 99/51111 PCT/$P99/01232 mixing screw of the extruder is re-started and stopped.
The extruder constitutes the pre-melter, which continuously mixes the components, forming them into a usable reactive adhesive that can be processed immediately.
Only as much reactive adhesive is mixed, produced and melted as is required for the respective application. To this point, large quantities have been measured out and must be completely processed. The disadvantage of this is that waste is produced when the required quantity is smaller than the produced quantity, whezeas, i.n the novel method Of the invention, only the desired quantity is produced.

In the method of producing a two- or multi-companent adhesive (K), at least one adhesive component is used in solid form, such as a granulate (G), or liquid form, and at least one other adhesive component is used in solid form, such as a granulate (G), or in liquid form as a liquid (F). The two adhesive components are heated, in a specific proportional ratio, by pressure and frictian in a conveyor track, and mixed to form the liquid adhesive (K);
