Description

DRY COMPOSITE FOR INDOOR SKIN, PRODUCTION AND USE
THEREOF
The object of the invention is a dry composite for the producing an indoor skin or decorative mortar and methods for the production and application of the indoor decorative mortar to create an aesthetic, easy-drying, easy-washable, removable and highly air- permeable indoor skin.
In line with the development of the construction industry, and that of interior decoration in particular, as well with the pursuit to create ever more aesthetic interior spaces, there seems to be an increasing need for being able to achieve better properties by means of the composition of the indoor mortar and by selecting the ratio of the materials in the mixture. Namely for the indoor skin to dry more quickly, to have better air-permeability, to adhere better to the wall, and to be removable, washable, or be scraped off more easily and quickly later.
According to the state of the art, the Hungarian patent application under registration number HU 209 275 relates to a skin product containing a plastic and inorganic adhesive material. The invention relates to a skin product containing inorganic and carboniferous adhesives that can be applied in mortar consistency. The product is characterised in that it contains 8-15 mass portion of (40-54 m%) plastic dispersion, 2.5 mass portion of potassium or sodium water glass, 65-80 mass portion noble stone chip and mixed thickener besides other subsidiary and film-formation enhancer materials. In case of this solution, the adhesive material is the water glass, in certain cases cellulose is used therewith.
The Hungarian patent application under registration number HU 216 298 relates to gypsum based compositions, and wall covering plates, applicable as a building and finishing material and a method for the manufacture of the composition. The solution described in this application relates to such improved-quality, complex material that is manufactured by mixing ground gypsum and host granules of a stronger material, e.g. ligneous fibre to create a thin suspension, the suspension is heated under pressure until the gypsum transforms to calcium-sulphate-hemi-hydrate: then the warm suspension is basically dehydrated before rehydrating the hemi-hydrate into gypsum again. The material so created is such a homogenous mass that includes gypsum crystals physically binding to the separately standing host granules. The invention also relates to such an improved-quality wall covering plate which has exceptional fire-proof, dimensional stability and solidity qualities, and is manufactured by the complex material composition is pressed before hydration for achieving the final shape. In the case of this solution the cellulose used with the gypsum is included in the mixture to moderate the binding of the gypsum.
The Hungarian patent application under registration number HU 210 564 describes a method for finishingwet walls and/or walls containing salt, which is characterised in that a spattered basic mortar containing hydrophobic additives and air-entraining agents and/or
5 light porous agents is applied on the wet walls and/or walls containing salt, directly to the entire surface, then, after the consolidation of this, the renewing mortar is applied. The mortar mixture is characterised in that it contains hydrophobic additives, thus silicone,
■ metal soap, ammonium salts of fatty acids, and air-entraining agents and/or light porous agents in addition to the customarily used hydraulical materials. The solution described0 therein is a lime-cement binding hydrophobic system, wherein optionally cellulose is used as an additive.
The Hungarian patent application under registration number HU 194 136 relates to a high-strength, long lastingly storable dolomite-based dry decorative finishing mortar and a method for the manufacture thereof. The dry finishing mortar described therein, related to its total mass, contains 73-77 mass% of crushed dolomite - with an ideal efficiency of space filling, having a nearly regular geometry, which is also mainly cubical, is sharply graded, has at least two size fractions - as an additive; 4-6 mass% of cement and 18 mass% dry- slaked lime as a hydraulic adhesives; and 0.3-0.5 mass% of colouring materials as additives. In the course of the method, the granule fraction is pre-mixed, and then the hydrophobic0 additives, the colouring materials and the hydraulic adhesives are admixed during intensive mixing. For decorative mortars, cement and dry-slaked lime can be used traditionally as adhesive materials, and Class I crushed stone with granules not larger than 5 mm and T7- class sand can be used as additive materials.
The Hungarian patent application under registration number HU 172 444 relates to a manufacturing method for construction-industry and insulation-industry mortars used for outdoor and indoor mortars and prefabricated products. In the course of the manufacturing method, 20-50 mass% of cement is added to 0.1-30 mass% vesicular volcanic 0.1-5 mass% thixotrope hydrosilicate and 5-20 mass% acidic or alkaline hydraulite grind. In an amount of 0.1-1 mass% calculated to the mass of the cement, colloid materials of at least 6000 molar weight - preferably clairecolle, gelatine, alginates and/or cellulose derivatives, such as carboxymethyl cellulose; and, if desired, in an amount of 0.1-1 mass% a foaming and air- entraining composition, preferably Al -grind; 0.1-3 mass% of glass-fibre, plastic fibre, asbestos, and other fibrous waste are mixed together, then, following homogenisation, elements or laminated products are produced in the manner known per se.
The international patent application published under no. WO 8801990 relates to the binding of refractory grain, specifically to an improved method of forming refractory articles using a complex organic hydroxyl-group containing colloid as a binder, which on firing leaves at least one refractory residue. During firing, the binder has the same oxide composition as the bound refractory grain.

An anionic colloid, preferably carboxymethyl cellulose may be used as ammonium salt; a polyacrylate may be used as metal or ammonium salt. The metal compounds are selected from alkoxides, acylates and preferably organic complexes of calcium, magnesium, aluminium, chromium, titanium, zirconium and/or silicon, or polymers thereof. The patent application under case number P 04 00586 published on 28.02.2006. relates to an indoor skin and a method for the production thereof, which - in addition to forming an aesthetical surface - ensures that an easily drying, easily washable, removable, and highly air-permeable indoor skin is produced. The indoor skin so produces is medium- strength, is applicable particularly indoors and can be stored long-lastingly. It is characterised in that it contains a powder-like OO-type stone grind amounting to 50-90 mass%; and 10-50 mass% of stone-powder or crushed stone screened-out to the appropriate size, i.e. 1-10 mm; and 2-5 mass% of cellulose-based adhesive material, preferably wallpaper glue. In the course of the method described, the cellulose-based adhesive material, preferably wallpaper glue is mixed in water to be clot-free, then the 50-90 mass% of 00-class stone grind and the 10-50 mass% of graded stone powder or crushed stone are added thereto, mixed to become a butter-like mixture, and the material so composed is applied on the wall 10-15 minutes after mixing, then the surface can be used after drying.
The disadvantage of the decorative mortars used in practice, such as the Baumit make skin is that even according to their factory brochure they are not suitable for application on fresh lime mortar or on lacquer or oil coats and plastic paints.
A further disadvantage of known solutions is that their setting time is short, thus in case of their use as indoor skin their application is difficult and inexpedient. It is another disadvantage that their use is only possible for a properly trained professional because their application and finishing require appropriate professional knowledge and skills. In case of their application on large surfaces, traditional plasters require the concerted work and cooperation of several professionals and assisting staff due to their short setting time. Furthermore, traditional plasters often contain substances that are harmful to health or are irritating, such as lime or cement, which limit or encumber their use indoors.
The aim set is to be solved by the solution according to the invention has been to develop an indoor finishing mortar that is better mixable, more easily applicable and finishable in the course of use and may be used more favourably indoors as pre-mixed finishing mortars intended for a similar purpose. In the course of developing the solution according to the invention, we realised that the set target can be achieved if the dry composite for the producing an indoor skin contains 80...90 mass% of OO-type stone grind as filling material, 7...9 mass% of 1-6 mm diameter crushed stone or plastic granules as a structure creating material, 1...2.5 mass% cellulose based adhesive as an adhesive material, and as a further additive material 3.5 ... 4.5 mass% of damping granules of 0.5 -1 mm in diameter.
Thus, the invention is a dry composite for the production of indoor decorative finishing mortar, which composite includes a filling material, a structure creating material, an adhesive material and a further additive material. Its characteristic is that it contains 80...90 mass% of OO-type stone grind as filling material, 7...9 mass% of 1-6 mm diameter crushed stone or plastic granules as a structure creating material, 1...2.5 mass% cellulose based adhesive as an adhesive material, and as a further additive material 3.5 ... 4.5 mass% of damping granules of 0.5 -1 mm in diameter.
In case of the preferable expedient realisation of the solution according to the invention, the filling material is a twice-ground, preferably a 600-fine dolomite and/or limestone grind.
In case of another preferable expedient realisation of the solution according to the invention, the stone grind is a sharply graded dolomite and/or limestone and/or gravel and/or quartz-sand.
In case of another preferable expedient realisation of the solution according to the invention, the cellulose based adhesive material is a carboxymethyl cellulose based glue, optionally CMC wallpaper glue.
In case of another preferable expedient realisation of the solution according to the invention, the composite contains damping granules as a further additive material, which damping granules are 0.5-1 mm diameter crushed stone, preferably sharply graded dolomite and/or limestone and/or gravel and/or quartz-sand.
In case of another preferable expedient realisation of the solution according to the invention, the size of the damping granules is 30% smaller than the size of the crushed stone used as a structure creating material.
In case of another preferable expedient realisation of the solution according to the invention, the coloured plastic granules used as a structure creating material is produced by the heat-treatment of plastic particles, and the plastic granules so produced are graded.
In case of another preferable expedient realisation of the solution according to the invention, the composite contains a preservative, which may be for instance a Neomagnol tablet (Valeant Pharma Magyarorszag Kft., HU) containing chlorogen sesquihydrate or a chlorogen.
Also, the invention relates to a method for the production of indoor decorative finishing mortar, primarily by using the composite according to the invention, which is characterised in that the dry composite is mixed into water with a ratio of 25 mass% calculated on the basis of the 100% mass of the composite, and the aqueous mixture so produced is allowed to stand for 30 minutes, then water is mixed to the skin in an amount of 2 mass% calculated to the mass of the finishing mortar, then we mix again the mixture so produced after 10...180 minutes of standing. In the course of a preferable application of the method according to the invention, upon adding the water of 2 mass% we may add a polyvinyl acetate based aqueous dispersion, as a further additive material, to the mixture, then we mix again the mixture so produced after 10...180 minutes of standing.
In the course of a preferable application of the method according to the invention, the temperature of the water used and/or admixed to the mortar is between 5 and 50°C, preferably is 15-20°C.
Moreover, the invention is also a method for the formation of indoor skin - primarily by using the composite according to the invention and the finishing mortar produced according to the invention - which is characterised by applying the mixed indoor skin with a stainless sleeker.
In the course of a preferable application of the method for forming the indoor decorative mortar, in case of a wall formed by mud surfacing or a wall made of gypsum plasterboard, a surface sealer is applied to the wall before applying the skin thereon. In the course of another preferable application of the method for forming the indoor decorative mortar, if there is a crack on the wall, we cover such crack by glass fibre cloth before applying the decorative mortar.
In the course of another preferable application of the method for forming the indoor decorative mortar, after the application of the decorative mortar, any excess finishing mortar is removed from the wall by holding the sleeker at a 45° angle.
In the course of another preferable application of the method for forming the indoor decorative mortar, the applied mortar is smoothed by means of a hawk made of a closed- cell-structure stirofoam, such as Nikecell or Hungarocell, in a vertical, horizontal, circular manner, or in an X shape manner, depending on the desired pattern.
In the course of another preferable application of the method for forming the indoor decorative mortar, after the application of the mortar, we form a uniform ross or cortex pattern by means of a rubber roller.

The preferable expedient uses of the solution according to the invention:
The carboxymethyl cellulose (CMC) based wallpaper glue used in the dry composite according to the invention is preferably a CMC type wallpaper glue available in commercial trade.
The polyvinyl acetate based aqueous dispersion optionally used in the course of mixing the dry composite for application is preferably a wood glue available in commercial trade. The polyvinyl acetate based aqueous dispersion used is, at room temperature, a glass- like thermoplast, which is mildly alkali-resistant and acid-resistant, and is used in the form of lacquers, paints, glues. The advantages of polyvinyl acetate based glues are: high adhesive capacity; they can be used immediately, without any preparations; they are not harmful to health because they do not contain harmful, organic solvents, they are not explosive or combustible. Its setting mechanism: wood or any other water-absorbing material gradually abstracts the water from the dispersed glue and thereby a coherent layer is formed.
The carboxymethyl cellulose based wallpaper glue, or optionally the wood glue replacing a certain proportion of the carboxymethyl cellulose based wallpaper glue makes the ready finishing mortar greasier, as a result of which the mortar will be more easily applicable.
Plastic particles optionally may be admixed to the pre-mixed dry product, which plastic particles are heat-treated before admixing it to the dry product, which results in their forming into small plastic balls. In some cases crushed stone is used as a structure creating material, which may treated before admixing it to the dry material by mixing it intensely in a mixer until the edges break down. In this case it rolls better on the wall in the course of application.
By increasing the size of the granules of the structure creating material, the amount of -l ithe carboxymethyl cellulose based wallpaper glue must be decreased, or in a certain proportion, the carboxymethyl cellulose based wallpaper glue must be replaced by a polyvinyl acetate based aqueous dispersion because failing to do so will result in the cracking of the decorative mortar. By increasing the temperature of the water used in the course of mixing the pre-mixed dry material with water the growing and thickening of the created aqueous mixture can be accelerated, the carboxymethyl cellulose based wallpaper glue will be less likely to clod, and therefore a less intense mixing needs to be carried out. As a final outcome, the skin will sooner become ready for application. The polyvinyl acetate based aqueous dispersion used preferably in the course of mixing, as a further adhesive material provides for chemical binding. This is advantageous when the amount of the carboxymethyl cellulose based wallpaper glue must be reduced. The carboxymethyl cellulose based wallpaper glue, optionally CMC, binds in a physical manner by drying. The advantage of this is that finishing for instance on plasterboard becomes easier due to the CMC. CMC binds better to the cellulose included in the paper layer of the plasterboard.
The preparation and application of the finishing mortar according to the invention is simple, it does not require any special preparations and the watering of the wall is not necessary. One does not have to hurry in the course of application because CMC does not bind but dries, therefore the finishing mortar according to the invention is especially suitable for forming decorations, forming decorative finishing that requires longer and more detailed elaboration, forming stuccos, which could not be achieved in a simple manner with traditional finishing materials.
If the structure creating material is plastic granules, then the coloured spots appear by polishing in the course of posterior refining, which coloured spots will serve as a plaster decoration.
The advantages of the solution according to the invention: The composition and proportions of the composite according to the invention ensure that it is better mixable, more easily applicable in the course of use, and that it remains on better than other pre- mixed mortars with the same purpose. It is a further advantage that its use does not require any special professional skills, it can be applied and smoothed simply following the instructions of use. It is favourable for indoor use because does not include any toxic substances or substances that are harmful to health either in its pre-mixed dry form or in its admixed form.
Its further advantage is that the admixed finishing mortar can be used after the work has been interrupted, even with an intermission of one or two days, provided that it has been stored covered. It can be applied in a thicker layer without crusting or cracking.
