Definitions

the invention relates to a method for local solidification of a Dämm forung of polymer particle foam granules, which for the insulation of a building, etc., in particular a clam wall masonry, is used, wherein the granules expandable polymer particles.
EPS milled material with a flat chip-like particle size of, for example, 0.5 mm to 4 mm and mixed into the introduced to be insulated hollow or receiving space.
the DE 31 32 279 A1 and the DE 28 30 914 A1 to provide the polymer particles used here with a binder, which is introduced together with these in the receiving space in the structure to be insulated.
the binder used here is latex, which is applied, for example, diluted onto the polymer particles. In this way, a kind of composite body or molded body is formed in the receiving space of the structure to be insulated, since the individual polymer particles are connected to each other after the curing of the latex binder.
the invention is therefore based on the object to provide a method with which on site with little effort trickling out of a Dämm thoroughlyung from a receiving space in a building can be reliably suppressed without disadvantageous additives must be used, in particular exert an influence on the flow behavior can.
This object is achieved by the method according to claim 1. This is characterized in particular by the step of expanding the polymer particles in situ at the point to be solidified in the insulating filling.
the invention thus provides for the first time to carry out an expansion step of the polymer particles on site at the structure to be insulated within the hollow or receiving space given there. It has surprisingly been found that such expandable polymer particles are solidifiable in the course of such end expansion under the prevailing conditions on construction sites and in conventional constructions, taking into account in particular the economic conditions, so that trickling is effectively suppressed.
the solidification is based on such a change in the surface condition of the polymer particles that it comes to a kind of welding between adjacent polymer particles. This is also supported by the limited space available in the receiving space of the structure to be insulated, etc., since the expanding during the expansion step polymer particles each other take the space and press each other.
a further advantage of the invention lies in the fact that the action on the granules can be limited to the relevant points in the Dämm forung while this is wetted in the art full volume with binder. This makes it possible according to the invention to keep the processing effort very low.
the procedure of the invention has the advantage that no additional fire load is introduced by a binder, etc. in the product. Since, according to the invention, no binder is used, there are no additional concerns with regard to ecological or health-endangering aspects of the ingredients of such an insulation.
polystyrene particles or the like it is generally known to subject polystyrene particles or the like to a double expansion.
polymer particles are prepared by a Vorexpandier Kunststoff means of steam and then used as a raw material for the production of insulation boards.
these pre-expanded polymer particles are introduced into a suitable mold and foamed there by means of steam and thus end-expanded, resulting in insulating blocks.
These are then cut to standard commercial and standard insulation boards or already have the desired final dimensions, so that no reworking is required. This process takes place at the factory, since here the expansion can be reliably and accurately controlled and, in particular, there is no negative interaction of the water vapor with neighboring components.
the polymer particles can be expanded by means of steam, which has the significant advantage that a medium is used which does not introduce any fire load into the insulation and also contains no active ingredients that would be of concern for health or environmental reasons.
the use of water vapor to assist in the expansion of polymer particles is a well-known and proven measure, so that this process can be carried out reliably.
the water vapor may e.g. be introduced via existing leaks on the building in the receiving space for the granules;
the polymer particles are first introduced pre-expanded polystyrene beads, since herewith a material with particularly good thermal insulation properties with low weight and good flow behavior is used.
EPS insulation materials instead of the pre-expanded polystyrene beads and a Regenerat of polymer particles, which as a residue in the factory production of rigid foam insulation, or from the decay of cavity fillings or as a secondary material from the material Rececyling and preparation of foam boards, in particular of EPS insulation materials , and may have properties, in particular an expandability comparable to the polymer beads, in any mixing ratio up to the complete substitution can be used.
the granules further milled material, which from the factory mechanical machining of hard foam Based on EPS, XPS or PUR-based, resulting in a high quality recovery of this waste.
the proportion of milled material can preferably be less than 60 vol.% Of the granules, i. can be used to a considerable extent, without the effect of the invention would be nullified.
the milled material is preferably used in a proportion of less than 50% by volume and in particular of less than 30% by volume of the granules, since here a greater stability of the adhesive bond can be achieved within the solidified region in the insulating filling.
the polymer beads may be provided with a fire retardant additive.
the flame retardant additive can be a brominated or chlorinated organic compound which has been found to be particularly useful in practice.
the fire retardant additive can be added in a proportion of 0.1 to 10 wt.% Based on the weight of the polymer beads.
the intermediate material in the production of insulating panels namely pre-expanded polymer beads
the intermediate material in the production of insulating panels can be used directly in accordance with the invention and can be used to produce a locally consolidated zone in the insulation in a building structure.
the cavity is subsequently filled in a building with double-shell masonry by means of a Dämm thoroughlyung of polystyrene particle foam granules.
the granules have a bead size ⁇ 6 mm in diameter and is introduced under low pressure into the receiving space within the wall.
the polystyrene beads are distributed throughout the available space due to their good flowability. If the receiving space is e.g. However, in the joint area of two components of the outer wall does not produce a tight seal, the polystyrene beads can trickle out of the receiving space in this area.
the respective leakage point should not be large enough to permit effective evaporation of the granules, it is also possible to provide access openings e.g. formed by a drilling process through which the water vapor can be passed.
a window is subsequently formed in an existing double-walled masonry with a Dämm convenientlyung of expandable granules in the core. This requires a corresponding opening in the wall getting produced.
a suitable number of access openings which are located at a predetermined distance from each other, are bored adjacent to the location of the window to be produced, through which steam is then introduced into the insulating filling. The subsequent expansion of the polystyrene beads in the insulation fillet thus solidifies the edge area around the window opening to be created, so that a separating cut can be carried out here without granules emerging from the insulation layer.
a passage opening for the passage of a water pipe e.g. an external connection for the water extraction with Dämm forung made.
a passage opening for the passage of a water pipe is limited locally and introduced through a single access opening water vapor in the Dämm forung. This makes it possible to achieve a solidification of the insulating fill in this area, so that subsequently the larger hole for the passage of the water pipe can be formed without this granules would escape from the core area.
the invention can thus be carried out both with initially introduced expandable polymer beads and with 100% recycled or already incorporated regenerate, with or without an addition of milled material from expanded polymer.
targeted local areas can be solidified in a Dämm thoroughlyung;
