Abstract

Construction material formed by a matrix (1) of plaster or plaster and a series of inserts (2, 2'), characterized in that the inserts (2, 2') comprise fragments of a wind turbine blade. The inserts (2, 2') comprise a combination of fiberglass (2') with epoxy and expanded or extruded polystyrene (2). It is applicable in plates, as plastering material, for sculptures, etc. (Machine-translation by Google Translate, not legally binding)

TECHNIQUE SECTOR

The present invention relates to a construction material, preferably for making plates but also for other plaster or plaster objects. It allows the recovery and reuse of elements that were previously discarded in landfills, while offering an improvement in the physical properties of the material.

STATE OF THE ART

The use of sheets and other bodies of plaster or plaster as decoration, finishing or to make partitions inside buildings is known. This type of plates frequently has internal reinforcements in the form of inserts. The inserts can be made of hemp or other fibrous material or even be metallic to define hooks and supports.

On the other hand, wind energy has undergone spectacular growth in the last 30 years, which implies that many wind turbines need to be updated, maintained or directly dismantled. This implies that it is necessary to treat and recover or reuse many components. In the case of motors, electric lines... there are already known procedures to recover these metals. However, the blades have not yet been adequately recovered and end up in inert landfills. However, its material can be recovered and has properties that can improve the mechanical behavior of plaster and plaster.

The Applicant does not know of any other way to recover the material from the blades and obtain the same advantages.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a construction material according to the claims.

The construction material is made up of a plaster or stucco matrix and a series of inserts, which comprise fragments of the wind turbine blade. Especially fiberglass, with or without epoxy coating, and expanded or extruded polystyrene.

This material is especially useful for covering or partitioning plates, and also for applying in mass on surfaces for plastering, etc.

Other variants will be discussed at other points in memory.

MODES OF CARRYING OUT THE INVENTION

An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.

Figure 1 shows an example of the construction material, formed by a matrix (1) of plaster or plaster and a series of inserts (2,2') corresponding to fragments of wind turbine blades.

The inserts (2,2') are formed by the particles coming from the crushing of the blades, once the metal parts have been removed. The particles are separated by size to ensure that the final granulometry is the desired one. They incorporate pieces of expanded or extruded polystyrene (2) and fiberglass (2'). This glass fiber (2') is embedded in epoxy, although this can be removed chemically. The fiberglass inserts (2,2') (2') are substantially thin, and provide mechanical resistance. Those made of polystyrene (2) provide lightness and thermal and acoustic insulation. Depending on the objective sought, they will be used of one type or another or in combination. They can be oriented by means of vibration, removing...

The construction material will normally be used in sheets, for false ceilings, partitions (such as the one known under the registered trademark "plasterboard"). It is also possible to use it for plastering, in the manufacture of plaster or plaster sculptures, etc.
