DE3320060A1 - Process for covering insulating panels and sheets with minerally bonded plaster - Google Patents

Abstract

According to the current state of the art, it is not possible as yet to provide insulated surfaces with a minerally bonded plaster without considerable cost. According to the process of this application, an adherent surface for minerally bonded plaster is applied to the insulating materials known in constructional engineering. The adherent surface comprises sands of which the grain size is dimensioned such that they ensure adequate adherence for a minerally bonded plaster. The adherence of the sand on the insulating material is accomplished by chemical two-component adhesives having a high curing rate. The adherent surface can be applied both to already insulated surfaces and at the works to the insulating material prior to installation.

Process for coating insulation panels and foils
with mineral-bound plaster

It is assumed that in civil engineering the most diverse Materials are used as insulating and insulating materials.

According to the current state of the art, it is not yet
possible, insulated or without significant expense
to provide isolated surfaces with a mineral-bound plaster. The application looks at a process that enables surfaces that have been covered or covered with an insulating or insulating material, at a later point in time with a normal, commercially available one
To provide mineral-bound plaster, as known in construction technology.

The technical novelty is characterized by the fact that the insulating and insulating material used largely thereby is protected against mechanical and weather influences. This makes it possible to choose which one to use to expand the coming insulation and insulation materials.

Using the example of polyurethane, the applicant explains the extensive Enlargement of the area of application.

Polyurethane is state-of-the-art for insulation and Isolierswecke previously used as in-situ foam or in the form of panels. Although polyurethane foams with the highest Insulation and insulation values in the construction industry be .-. '. Nnt, the area of application was limited by the fact that, for example, exterior facades insulated with polyurethane foam from Buildings only with considerable expenditure due to the application of a special layer of rubble such as a curtain wall made of metal, plastic or asbestos cement, have been protected from the elements and mechanical damage.

The method developed by the applicant provides that on the surface of the insulating and insulating material such as polyurethane or other suitable insulating and insulating materials, a primer for minerally bound plaster is applied chemically. (See Fig. 1)

The technical novelty of the process is further explained by the fact that on all known in construction technology Insulating and insulating materials such as mineral fiber boards, expanded plastics such as polystyrene, polyurethane, phenol aldehyde and urea, cork or any other däxnm- and insulating material can be applied to the primer can.

The reason for detention. (Fig. 2) consists of sands, the grain size of which is dimensioned in such a way that it ensures sufficient permanent adhesion for a minerally bound plaster

The adhesion of the sand to the insulation material is increased through chemical reaction adhesives with high curing speed received.

The sand, which is evenly applied, lies with it at least 1/3 of the surface of the single grain of sand mechanically firm in the rapidly hardening chemical reaction ^ Glue. The maximum adhesion of the individual grain creates an evenly coated, sanded surface, to every common put known in construction engineering can be applied effortlessly using the customary methods. can.

The insulating and insulating material coated in the manner described is in no way impaired in the physical puncture.

The further technical novelty is characterized in that it is possible, according to the method described, large Areas such as inner and outer walls in horizontal or to permanently insulate or insulate vertical construction. Destruction of the insulation material by inechani see or weather seiv, rivers vlrd permanently avoided.
