Abstract
A coating system for cement-grouted floors consists of an elastic floating layer that lies on the floor and is made of one or several inorganic binders, an organic cementcompatible polymer and optionally organic or inorganic fillers, and of a covering layer made of one or several inorganic binders and optionally cement-compatible polymers and inorganic aggregates.
Description
218~162 T~e invention concerns a coating system for cement--bound earth bg mesns of which surface damsges and cracks are covered over and which can especiallg a~so be driven over with ve~icles.
From tbe practice, coating systems are known which serve the purpose of bridging over crac~s and damages in concrete walling, wherebg, on the one hand, it is prevented that such damages spread outand, on the other hand, a smooth, crack-free surLace is ensured~ which prevents a penetration of dirt, thawing salts, solvents and atmospheric compone~ts. ~he surfacesof such coating s~stems should preferablg be mechanically capable of bearing a ~osd and especially permit driving o~er.
In the case of known coating systems, on t~e concrete substrate tbere is usuallg applied a priming of organic binding agents or of a cement-compatible synthetic material and additive; tbere possiblg takes place an additional smooth fil~ing in order to level out unevennesses. On this priming there is then applied a synthetic material lager in which, in order to increase the tensile strengt~, fabrics or fleece of glass or sgnthetic material fibres can additionally be intro-duced. On this synthetic material layer is tben applied a surface of a chemicall~ or mechanicallg stable material with a high E-module, usuall~ of between 300G and lOOOO N/mm2. ThiS lager usually cOnsists of an organic binding a~ent with inor~anic filling 2la4l62 materials which give rise to the hardness.
As organic binding agents, there are preferably used two-component reaction sgntbetic material~ (EP, EP-PU, PU, PMH, self-vulcanising rubber,. polyesters etc.). As filling materials of the covering layer, there are used quartz sand, corundum in suitable grain size, whereby the hardness and non-skidding of the surface layer is brought about (cf. EP O 475 OCO-Al, GB 2 Q45 109 A, CH 659 813 A5, ~E ~8 ~8 ~20 Al).
Since the synthetic material layers adhere compara~ivelg poorly to cement-bound surfaces, in these documents it is suggested additionallg to roughen the surfaces by brushing, sand-blasting or to provide with borings and to apply special bondings (primers), which makes this process expensive. Furthermore, the coating s~stems are.themselves comparativ~ly expensive and, for the bridging over of cracks, must be applied in relatively thick lager because of their low mechanical strength. The incorporation of fabrics or fleece for the increasing of the transverse tensile strengtb is also advsntageous.
Therefore, the task exists to fir,d a coating system which is inexpe~sive and, above all, possesses the strength necessary for driving over.
This task is solved according to the features of the main claim and promoted bg the features of the subsidiary claims.
2184~62 It appears to be surprising that a comparatively hard 7ayer of preponderantly inorganic binding agents, such as cement r Efa fillers etc., whicn contains, to only a comparativel~ small extent, organic cement-compatible polymers as additipnal binding agent andpossibly inorganic or organic filling materials, also in the case of ~igh loading s~ow a sufficient strength and do not break or crack so that such lagers can also cover over crac~s and, in the case of driving over, do not break.
This layer, designated as ground or floating layer, usually consist of 5~ to 50% of the inorganic binding agent, 5% to 60% of the organic po~gmers and G - 80%
of filling materials, Cement, Efa filler etc. is used as inorganic binding agent. Aqueous dispersions of acry~ates are especially used as organic polymers. As filling materials, there can be used sand, s~one chippings, slag meal, fly ash and possibly also finely powdered organic materials, In principle, the covering layer is made up of the same products as the base lager but, for t~e increasing of t~e s~rength, the proportion of the inorganic binding agent is increased to 5% to 70% and the proportion of the organic poI~mers reduced corres-2~ po~dingIy to 3~ to 5C%. Furthermore, as filling materials, there are contained 10~ to 70~ of hard inorganic powders, such as guartz sand, corundum, slag meal etc. In order particularly to make t~e surfaces especially hard and robust, appropriate coarse-grained filIing materials are additionally sprinkled on the surfsce, whereby, besides an especial hardness, there is also produced an increase of the non-slipping on such earth.
For the application of t~e coating system according to the invention, the substrate is cleaned from contaminations, such as e.g. sand, dust, oil or grease residues and loose mud layers or brittle parts, as well 10 as coloured coatings, bg means of rotating steel brushes, rotators etc. Thereafter, the earth is made matt moist, whereb~ a puddle formation is to be avoided~
In the case of very drg or very stron~ly absorhing substrates, a priming is possiblg also to be used which prevents an absorption o~ moisture from the floating lager .
~ ement, polymer dispersion and additive materia~s are mixed in the necessarg amounts and mixed with water until 8 w~rkable mass results which is then spraged, smootbed on or cOated on. ~be cement onl~ binds slowlg at low temperatures and, below 4C, practically does not bind so that, in the case of working up, temper-atures o-f at least 8 - 10C, preferabIy room te~per-atures, should prevail. In the case of extreme weather conditions (strong wind, direct suns~inej, it can be advantageous to cover over the finished layers with foils until the hardening through in order to prevent a premature drging out or to avoid a wasbing out by rain.
After h~dening through of the floating la~er, the c~vering layer is also applied in tbe same way and possibly sprinkled in the still moist state with appropriate sand or corundum g~anulste~
The coating sgstems accordin~ to the invention are hard and tough enougb in order to resist usual stressings and also to be capable of being driven over. If desired, however, in addition a fabric or fleece can also be incorporated not onl~ into the bsse layer but also into the covering layer for the strengthening, whereby tben, in the usual way, first onlg about half of the layer thickness is applied, the fabric laid thereon and the remainder of the layer applied. The mixtures according to the invention are usually adjusted to be so pasty that they penetrate the fabric and bring about a secure adhesion within the whole lager laminate.
