Abstract

Building board for thermal and acoustic insulation of buildings, consisting of an insulating core (2) and at least one cover plate (1), the essence of which is that the insulating core (2) the building board consists of a foam-based board PUR recycled material firmly attached to at least one cover layer (1) of cement-cement or wood-magnesite material. The plates forming the core (2) are either made of foam or a mixture of a foam layer and a polyester layer fabric.

Description

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

BACKGROUND OF THE INVENTION

Up to now, building boards made on the basis of PUR-recycled foam made of cellular polyurethane foam or a mixture of polyurethane and polyester fabric are known. The pulp is obtained from parts of cellular polyurethane and textile parts used for the production of seats and parts of car interior equipment. Foam boards have 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 drawback for some construction applications is their low strength, flammability and instability under UV radiation. 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 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 safety, resistance to microorganisms, wood-destroying insects, rodents, molds and fungi. From the point of view of utilization of waste raw materials and lower economic demands of production there can be lower price of these building boards, which brings economic benefit.

BRIEF DESCRIPTION OF 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 two-layer building board. In FIG. 2 shows a three-layer building board.

Examples of technical solution

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

The building board 1 of FIG. 2 is identical to the previous embodiment, except that it comprises one layer of insulating core 3 and two cover plates 2, wherein the insulating core 3 is located centrally between the cover plates 2.
