Definitions
- the present invention relates to a device for producing a ready-to-use filler compound by mixing a binder and a hardener component according to the preamble of claim 1.
- Such devices for mixing at least two components are used, for example, in the production of leveling compounds, a hardener component being admixed with a 1 to 2% proportion of a binder component in order to produce a hardenable leveling compound.
- the IVlischvoriques has for the supply of the respective components inlet openings, via which the components are added into the mixing chamber.
- the components are stored in upstream receptacles such as cartridges or the like, with the IV device being part of a means for providing putties.
- Such devices for mixing at least two components are used, for example, in the production of fillers, wherein a hardener component with a 1 ... 2% content of a binder component is mixed to produce a curable filler.
- the IVlischvoriques has for the supply of the respective components inlet openings, via which the components are added into the mixing chamber.
- the components are stored in upstream receptacles such as cartridges or the like, with the IV device being part of a means for providing putties.
- Such a device for producing a ready-to-use filling compound for the filling of surfaces which relate for example to vehicle bodies, is known from DE 203 07 518 U l.
- the device has two storage containers arranged at a base station, of which one is filled with a binder component, namely a putty component, and the other with a hardener component.
- the two components each have a Feed channel continuously fed to a mixing chamber in which the components come into contact with each other.
- the mixing chamber is formed from a tube section of a flexible tube, on the outside of which press rollers engage, which compress the tube section and simultaneously drive around a longitudinal axis.
- the components Due to the friction occurring and the adhesion of the components to the inner wall of the tube, the components are mixed together. After the mixture has passed through the tube section, it arrives at an outlet opening provided on the tube, where it emerges continuously from the tube.
- the tube wall is made of an airtight plastic, so that the air surrounding the tube during the mixing process does not get into the mix and can be trapped in this in the form of pores or voids.
- EP 1 900 443 A2 describes a device system for producing a ready-to-use filler compound by mixing a binder and a hardener component.
- This device system for mixing at least two components, in particular a binder component A and a hardener component B, into a pasty or liquid mixture for producing a ready-to-use filler for filling surfaces, for example vehicle bodies comprises a support plate with an inlet opening for the supply of the binder component A from a storage container arranged on the support plate and with at least one further inlet opening for the supply of the hardener component B from a reservoir arranged on the support plate and outlet openings connected to the inlet openings via supply channels in the support plate, and a Functionally connectable to the support plate mixing device with a number of outlet openings in the support plate corresponding number of corresponding with the outlet openings of the mixing device, the h ohlzylinderartigen stator having a formed in its wall discharge opening for the mix and a concentrically arranged in this rota
- This mixing device has a hollow cylinder-like stator part and a rotor part rotatably received in this concentric about a longitudinal axis and the mixing chamber between the stator and the rotor part ringpaltartig formed, wherein a plurality of molded on the stator first mixing teeth radially inwardly and a plurality of second rotor teeth integrally formed on the second mixing teeth radially extend outwardly into the mixing chamber in order to move by means of a rotary movement of the rotor part in the stator, the mixing teeth against each other and to provide a mixing of the two components, wherein the stator at least one, preferably two with the Mixing chamber has connected inlet openings for the hardener component
- the hardener component has to travel a relatively long distance until it enters the mixing device, because the distance between the outlet opening and the device plate or support plate of the device and the inlet opening of the mixing chamber of the mixing device is relatively large, so that trapped in the mass of the hardener component and entrained air bubbles are transported into the mixing chamber and when mixing the hardener component with the binder component are not completely eliminated by the rotational movement of the mutually running mixing teeth of the mixing device.
- the present invention seeks to provide a device for a homogeneous mixing of two components and a hardener component, for producing a ready-to-use fully curable filler, wherein the hardener component from the outlet of the outlet opening, the container for the two components carrying device plate up to the mixing chamber of a mixing device of the device has a very small path, preferably a distance of 1 mm, with a diameter of the flow channel of 1.5 to 1.6 mm has to cover in order to shorten the way Wegzeit save until the binder component meets the hardener component, so that the first part of the binder component emerging from the outlet opening already contains the necessary amount of hardener of about 2% and thus a uniform time until gelation of 2 to 3 Minutes is reached.
- the invention consists in a device according to the preamble of claim 1, which is designed so
- the supply of the binder component A and the hardener component B by means of control means to the mixing chamber of the mixing device is such that a small amount of hardener component B by expansion of the micro-air bubbles as pre-injection compared to the supply of Binder component A is supplied to the mixing chamber, wherein the device for effective expansion of the micro-air bubbles has a half o- to three-quarters filled with hardener component B cartridge-like container, wherein the outlet opening in the device plate for the exit of the Hardener component B at a distance from the inlet opening of the mixing chamber is preferably 1 mm for a path length of 1 mm for the flow of the hardener component B is disposed in the mixing chamber, wherein the supply channel for the hardener component in the device plate in a adjacent to the outlet opening in the device plate lying section has a diameter of preferably 1.5 mm or 1.6 mm, and wherein prior to the start of the continuous mixing process by means of the expansion of the micro-air bubbles amount of 1.2 grams to 5
- the mixing device on the device plate in the region of the outlet openings for the two components A and B is arranged such that the outlet opening for the hardener component B in the device plate at the inlet opening or inlet hole for the hardener component B of the mixing chamber and is congruent with this, wherein the distance of the outlet opening to the inlet opening of Mixing chamber of the wall thickness of the mixing chamber wall of preferably 1 mm, so that the path length for the flow of the hardener component B from the outlet opening in the device plate in the mixing chamber corresponds to the wall thickness of the chamber wall.
- the invention provides that the exit of the hardener
- Component B is laid so far that the hardener component only has to travel a little way, so to speak, only to the material thickness of the mixing chamber of the mixing device of 1 mm, to be effective as a pre-injection, especially as the binder component A in their viscosity significantly thicker than the viscosity of the curing agent component B. It is therefore necessary that the mixing device has to remain on the device until a new mixture is made.
- the micro-air bubbles present in the hardener component B which is preferably a benzoyl peroxide paste or a cyclohexanone peroxide paste, ie the air bubbles, are used here to achieve a very small amount of hardener component B for the pre-injection in the mixing of the binder component A, which is a polyester composition, used with the benzoyl peroxide paste of the curing agent component B.
- the binder component A which is a polyester composition
- a paste of benzoyl peroxide and plasticizer contains a very small amount of micro-air bubbles, which cause a low compressibility of the material.
- This effect is however as a function of the filling level of hardener component in the cartridge-like container to different degrees, with the result that at a complete filling of the cartridge-like container with the hardener component B high compressibility achieved by the plurality of micro-air bubbles in the hardener mass and this compressibility allows a flow of hardener component B to the IVlischvoriques, especially since it is sufficient for a completely filled cartridge-like container with hardener component that a Nachdschreib effect effect that is sufficient to already a small IVIenge of about 0,
- Component prior to the beginning of the actual feed of binder component and hardener component for the mixing process is no lead to achieve a proportional application of the binder component and the hardener component, because the hardener component may not be more than 4%, because otherwise unacceptable reactions occur and u. a. Also, a peroxide bleaching effect of the colorant pigments contained in the hardener component may occur.
- a second technical solution that can also be combined with the first technical solution is that the flow channel for the hardener component B in the device plate has a diameter of 1.5 to 1.6 mm, so that the way the hardener mass is just as large as the wall thickness of the mixing device, namely 1 mm. Due to the low viscosity of the hardener component B, mixing with the supplied binder component B in the mixing zone thus occurs immediately, resulting in a slight pre-injection, or pre-injection is unnecessary. The pre-injection may thus be wholly or only partially necessary.
- the invention comprises the use of a device for mixing at least two components, in particular of a binder component A with a hardener component B in a pasty mix for producing a ready-to-use filler for the filling of surfaces of vehicle bodies with the features of the claims for shortening the path of the hardener component B to the binder component A to obtain a uniform time to gelling the two components of 2 to 3 minutes.
