DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an absorption mat, which is especially suited for organic hydrocarbons in liquid, paste-like or solid form, for example, for oils, fats, fuels or solvents.
BACKGROUND OF THE INVENTION
It is known that liquid, paste-like or solid hydrocarbons have a higher affinity for specific materials than with respect to water. Accordingly, the hydrocarbons can be received or absorbed in bodies manufactured from these materials.
Previously, these characteristics have rather been viewed as a disadvantage because a swelling of the components manufactured from the particular materials resulted.
SUMMARY OF THE INVENTION
The invention is, however, directed toward using the known characteristics of these materials in an advantageous manner in order to take up, trap or separate liquid, paste-like or solid hydrocarbons in order to protect the environment.
Any place where it cannot be prevented that such hydrocarbons escape or are emitted because of a work process or treating process, it is of special importance that these hydrocarbons do not directly reach the environment in an unwanted manner and especially that the substances do not reach the ground or are diverted thereto.
For this reason, it is the subject matter of the invention to provide absorption mats which can be placed on floors, ramps and service aisles in the area of treatment facilities or processing facilities or the like.
According to the invention, these absorption mats are primarily characterized by at least one plate-like or block-like molded body made of oil and/or solvent absorbing material or oil and/or solvent receiving material on the basis of, for example, NR-rubber, IR-rubber, IIR-rubber or BR-rubber which is seated or accommodated in a trough or the like which is open at one end, namely, from above, with the trough being made of a material being an oil and/or solvent resistant or at least containing an oil and/or solvent resistant layer.
The plate-like or block-like molded body can be made of elastomers, which absorb or take up organic hydrocarbons, for example, NR-elastomers, RI-elastomers, IIR-elastomers, BR-elastomers, SBR-elastomers but also thermoplastic elastomers (TPE), thermoplasts or duroplasts.
In a porous, cellular or foamed form, these materials can be processed to the plate-like and/or block-like molded body for increasing the absorption capability. Preferably, the molded body comprises rubber granulate brought into a compound which maintains a form or rubber shavings.
The placement of absorption mats configured in this manner in the area of treatment and/or processing facilities affords the advantage that the organic hydrocarbons are reliably trapped when they drip and are retained against an unwanted removal into the environment. The organic hydrocarbons are removed by means of the treated or processed workpieces.
It has been proven advantageous according to the invention when the rubber granulate or the rubber shavings are bonded by oil and/or solvent resistant binding agents and/or by vulcanization to the plate-like and/or block-like body.
An especially great effectiveness of the absorption mat is then obtained in accordance with the invention when the rubber granulate or the rubber shavings of the molded body are porous, for example, when they comprise cellular rubber, microcellular rubber or foam rubber. It is understood that the molded body can, however, contain also granulate or shavings made of solid material.
The invention provides that the plate-like and/or block-like molded body is provided over most of its thickness with recesses, for example, grooves, rills, holes or a combination thereof so that the swelling of the rubber granulate or of the rubber shavings is possible without difficulty in the course of the absorption of organic hydrocarbons. It is, however, also possible to impart a profile to the entire surface of the molded body and/or the arrangement of inner spaces therein.
The trough or the like comprises, in accordance with a further embodiment of the invention,
