Abstract
A composition comprising at least one inorganic filler, at least one film-forming polymer dispersion, at least one plasticizer and water, a process for producing it and the use of this composition as low-shrinkage paste-like knifing filler and/or joint grout are proposed.
Description
Low-shrinkage paste-like knifing filler
The present invention relates to a composition comprising at least one inorganic filler, at least one film-forming polymer dispersion, at least one plasticizer and water, a process for producing it and the use of this composition as low-shrinkage paste-like knifing filler and/or joint grout.
In building and construction, gypsum plasterboards are widely used for producing light, non- load-bearing interior walls and for cladding. For this purpose, the gypsum plasterboards are generally fastened to a substrate construction and the screws or nails and also the joints between the individual boards are filled by means of a knifing filler or joint grout.
Products based on gypsum plaster and dispersion-based products are used for the filling work. Knifing fillers based on gypsum plaster are produced as factory dry mortar and are mixed with water on the building site. On the other hand, the dispersion-based knifing fillers are offered for sale as fully formulated paste-like products which can be processed without addition of further components.
The paste-like knifing fillers are, in particular, very simple to work (easy to work, good non- sag properties, easily closing surface). Compared to knifing fillers based on gypsum plaster, the dispersion-based, paste-like products which cure by drying and resulting film formation from the latex dispersion present but display a significantly increased joint contraction or shrinkage so that a number of knifing operations, usually three knifing operations, are necessary to obtain a sufficiently smooth surface. This is a considerable disadvantage for the user.
US 6,476,099 describes a dispersion-based knifing filler having reduced crack and crater formation and reduced shrinkage, which comprises a surfactant which consists essentially of hydrocarbon-substituted sulphate, sulphonate, sulphuric acid or sulphonic acid. It was an object of the invention to provide an alternative, dispersion-based, low-shrinkage knifing filler which allows joints to be closed smoothly by means of a few, preferably two, knifing operations and is nevertheless easy to work (easy to work, non-sag properties, easily closing surface). Furthermore, it was desirable for drying of the knifing filler to be accelerated, which allows more rapid progress in the building work.
These objects are achieved by the features of the independent claims. The dependent claims relate to preferred embodiments.
It has surprisingly been found that the use of various additives makes it possible to obtain a paste-like knifing filler which displays greatly reduced shrinkage values at a significantly decreased water content and can nevertheless be worked easily. This enables a smooth surface to be obtained by means of the knifing filler of the invention using two knifing operations. The knifing filler of the invention also dried more quickly than knifing fillers of the prior art due
to the reduced water content, which is a significant advantage for the user, particularly at low temperatures (5°C).
The present invention accordingly provides a composition which comprises at least one inor- ganic filler, at least one film-forming polymer dispersion, at least one plasticizer and water.
The inorganic filler is preferably selected from among limestone, calcium carbonate, chalk, marble, calcite, aragonite, dolomite, calcium sulphate dihydrate and mixtures thereof, particularly preferably as ground limestone.
This filler is advantageously present in finely divided form. In particular, at least 99% of the particles of the filler are smaller than 250 μιη, since larger particles would no longer give a sufficiently smooth surface. The film-forming polymer dispersion is advantageously an aqueous dispersion selected from among polyacrylates, polyurethanes, polyurethane/polyacrylate hybrids, styrene-acrylate copolymers, styrene-butadiene copolymers, polyvinyl acetates and mixtures thereof. Such polymer dispersions easily form films on drying. The amount of water present in the composition of the invention is advantageously kept as small as possible in order to reduce shrinkage and aid drying. The plasticizer present in the composition of the invention ensures that the composition remains easy to work despite the reduced amount of water. The plasticizer can be polyacrylic acid. As an alternative, the plasticizer can be selected from among comb polymers.
For the purposes of the present invention, the term "comb polymer" refers to copolymers which have both polyether functions and side chains having acid functions, in each case on a main chain, and can be obtained by free-radical copolymerization of acid monomers and polyether macromonomers.
The comb polymers are preferably copolymers which comprise structural units derived from (meth)acrylic acid, maleic acid, polyalkylene glycol vinyl ethers, polyalkylene glycol allyl ethers and/or polyalkylene glycol esters of (meth)acrylic acid.
The drying of the composition of the invention with low shrinkage can be improved further by at least one superabsorbent polymer (SAP) being present. Superabsorbent polymers can store a comparatively large amount of water without an increase in volume and can release it again without a decrease in volume. On drying, the particles of the superabsorbent polymers presumably act as space reservers until the matrix of inorganic filler and film-forming polymer has solidified to such an extent that further shrinkage is no longer possible.
The superabsorbent polymer is advantageously selected from among water-swellable polysaccharides, preferably starch derivatives, and water-swellable and/or hydrogel-forming polymers, preferably acrylate polymers having cationic structural units containing anionic and/or quaternary ammonium groups containing carboxyl groups and/or sulpho groups, and mix- tures thereof.
As an alternative, a non-ionic and/or ionic surfactant can be present. The non-ionic surfactant can be selected from among (block/random) poly(C2-3)alkylene glycols, fatty alcohol
(C2-3)(poly)alkoxylates, saturated or unsaturated fatty acid amide (C2-3)(poly)alkoxylates, (Cio-i5)oxo alcohol (C2-3)(poly)alkoxylates and alkylphenol (C2-3)(poly)alkoxylates and in each case the (Ci-4)alkyl ethers, polysorbates and alkyl polyglycosides thereof and also mixtures thereof.
The ionic surfactant can be selected from among anionic surfactants containing phosphoric acid groups, carboxyl groups and sulpho groups and cationic surfactants containing quaternary ammonium groups, and mixtures thereof.
Preference is given to at least one superabsorbent polymer and at least one surfactant being simultaneously present.
In addition, an aqueous polymer dispersion which does not form a film can be present. Such polymer dispersions can comprise multilayer polymer droplets having a polyacrylate core and a polystyrene shell in water. To improve the workability further, the composition of the invention advantageously comprises at least one rheology modifier which is preferably selected from among acrylate thickeners and copolymers containing sulphonic acid, and mixtures thereof. Further additives and auxiliaries are likewise within the scope of the present invention. The present invention further provides a process for producing the composition of the invention, which is characterized in that the above-defined components are homogeneously mixed with one another.
Finally, the present invention further provides for the use of the composition of the invention as low-shrinkage paste-like knifing filler and/or joint grout.
The present invention will now be illustrated with the aid of the attached examples.
Examples:
Production examples 1 -3 The inorganic filler (ground dolomite), the film-forming acrylate dispersion (Acronal® S 533), the plasticizer (Melflux® 2651 , a polycarboxylate ether comb polymer) and water and also the further constituents as per Table 1 were homogeneously mixed with one another. This gave three compositions suitable as paste-like knifing fillers. The viscosities of the compositions were determined immediately and after one day by means of a Brookfield viscometer. These values and also the working properties of the compositions are shown in Table 1 below. The shrinkage values were determined by means of a wedge test in which two gypsum plaster boards each having a thickness of 1 cm were arranged in parallel on a steel plate at a distance of 4 cm from one another. The gap was filled smooth using the compositions obtained from Examples 1 , 2 and 3. After drying, the depth of the maximum sinking was determined in mm.
It was found that the good properties of the basic formulation (Example 1 ) could be improved further in respect of the shrinkage behaviour by reducing the amount of water by increasing the amount of plasticizer (Examples 2 and 3). A further improvement in the shrinkage behaviour could be achieved by addition of a hydrogel-forming (superabsorbent) polymer (Example 3).
Production examples 4-7
Examples 1 -3 were repeated with the constituents as per Tables 2 and 3.
It was found that the good properties of the basic formulation (Example 4) could be improved further in respect of the shrinkage behaviour by reducing the amount of water by increasing the amount of plasticizer (Examples 5 - 7). A further improvement in the shrinkage behaviour could be achieved by addition of a hydrogel-forming (superabsorbent) polymer (Example 6) and further by the addition of an alkyl polyglycoside-type surfactant (Example 7).
