Mortar mixture for thermal insulation and / or fire protection and for universal applications, as well as processes for their preparation and use.

摘要

The mortar mixture can be performed in the form of a plaster mix as Dämmputz, for insulating building envelopes and it can also be performed as a top coat. However, the mortar mixture can be used for horizontal surfaces or used as Giessmörtel in forms, including compression molding. At least 20% of the mortar mix consists of glazed and thus closed, air-filled spheres of expanded silica or expanded perlite. These pearlite spheres are mixed with binders, additives as binders, an air entraining agent and / or other chemical additives as plasticizers, quick binders and polymers. The procedure for the preparation of the mortar mixture is such that pearlite sand is first sorted by means of a grading curve in different grain sizes. Each grain size is then inflated in a trickle channel with multi-stage temperature zones, so that the surface of the balls is vitrified. Such produced, glazed, expanded perlite is mixed together by the addition of binders and cellulose, air entrainers and / or chemical additives to form a homogeneous mixture. The mortar mix is used to insulate exterior or interior walls or floors of structures. For this purpose it is by means of a screw pump with screw (1) and elastically resilient and from the outside in the field of screw (1) acted upon by air pressure or oil pressure pump cylinder (3), which is housed in a pressure-resistant outer tube (4), via a hose (7 ) and injected through a nozzle (10) with or adding water to a wall to be insulated. In the application of the mortar mixture as a top coat, an aqueous dispersion is used as a binder.
