Abstract

Building board for thermal and acoustic insulation of buildings formed by an insulating core (2) and at least one cover board (1), the essence of which is that it is insulating the building board core (2) is a foam-based board PUR-recycled bonded to at least once a cover layer (1) of wood-cement or wood-magnesium material. The plates forming the core (2) are either from a foam layer, or from a mixture of a foam layer and polyester fabrics.

Description

Technical field

The technical solution concerns a building board for thermal and acoustic insulation of buildings and for the construction of noise barriers.

BACKGROUND OF THE INVENTION

So far, known building boards are manufactured on the basis of foamed PUR - recycled material, made of pulp from cellular polyurethane foam parts or a mixture of polyurethane and polyester fabric. The pulp is obtained from cellular polyurethane parts and textile parts used for the production of seats and car interior parts. Foam boards have a lower bulk density and compressive strength than boards made with a mixture of foam and textile. Both types are characterized by good thermal and sound insulation parameters. They are hygienically harmless and resistant to biological pests.

A disadvantage for some applications in the construction industry is their low strength, flammability and instability in the UV radiation. The low strength makes it difficult to use on vertical constructions as well as on more loaded floors and ceilings.

The essence of the technical solution

The technical solution aims to eliminate the above-mentioned deficiencies by creating a building board for thermal and acoustic insulation of interiors and exteriors of buildings, as well as for sound insulation in the creation of noise barriers.

The object is solved by the object of the technical solution, which is based on the fact that the insulating core of the building board is formed by a board based on foam PUR recycled firmly connected to at least one covering layer of wood-cement or wood-magnesite material. The core-forming plates are either a foam layer or a mixture of foam layer and polyester fabric.

Advantages of the technical solution are that the building boards produced in this way can be used for thermal and acoustic insulation of buildings for thermal insulation of exteriors and interiors of buildings in all parts of buildings and due to the high sound insulation ability also for sound insulation of partition walls, floors and ceilings as well as for the construction of noise barriers on roads. The wood-cement coating increases the strength and fire-resistance properties of these boards, protects the core from the effects of UV radiation and makes an ideal base for the application of plasters. Other advantages of the technical solution are its ecological and health harmlessness, about its resistance to microorganisms, wood-destroying insects, rodents, molds and fungi. In terms of utilization of waste materials and lower economic demands of production .U can also be lower price of these building boards, which brings economic benefit.

Overview of figures in the drawings

The technical solution is explained in more detail below with reference to the drawings. In the attached drawing of FIG. 1 is a schematic representation of a two-layer building board. In FIG. 2 shows a three-layer building board.

Examples of technical solution

The building board 11 according to FIG. 1 consists of one layer of insulating core 3 made of a foamed PUR recycled board and one cover plate 2 made of a wood-cement or wood-magnesite board, which are joined by gluing with cement milk or another adhesive by cold pressing.

The building board b according to FIG. 2 is identical to the previous exemplary embodiment, except that it comprises one layer of insulating core 3 and two cover plates 2, the insulating core 3 being centered between the cover plates 2.

Industrial usability

The product can be used wherever it is necessary to insulate buildings and rooms against heat leakage, for sound insulation of buildings and rooms and for the construction of partitions in buildings.

It can also be used for the construction of noise barriers on roads.
