DE19614110A1 - Preparation of wall or floor covering comprising fibres and binder dissolved in water to form paste - Google Patents

Abstract

Preparation of a floor or wall covering by dissolving fibres held together by a binder in water and then applying the paste to the surface, comprises the addition of a copolymer dye dispersion to the paste before application and then later applying at least one layer of pure acrylic dispersion onto the surface of the dried paste. Also claimed is a material used to make the paste, containing fibres and binder, with a separately added copolymer dye dispersion. Preferably a second acrylic layer is applied to the dried first acrylic layer. The paste contains 5-60 (30) vol.% dye dispersion. The acrylic dispersion can be diluted with water and contains no emulsifiers. Natural or synthetic fibres are used. The binder is methyl cellulose and/or potato starch. Metal fibres and/or mica components can be added.

Description

The invention relates to a method for manufacturing a floor / wall covering, in which one porridge from in Fibers dissolved in water and bound in a binder on a surface.

Such methods are, for example, for production of a wall covering known. With these procedures, the fibers bound in a binder dissolved in water and the resulting porridge, for example, by means of a spatula or using a spray gun on the Applied to the wall.

Since the fibers are mostly natural fibers, such as cotton, Viscose, jute, linen, hemp, flax and cell fibers such a wall covering is used atmumgs active, sound absorbing, free of toxins, odorless,  heat-insulating, humidity-regulating and anti static.

It is also advantageous that such a wall was easy to apply and later easy again is to be disposed of. In particular, such a wall covering no seams, such as from wallpaper existing wall coverings.

However, it is disadvantageous that the mostly methyl cellulose and / or starch, bound Have fibers easily removed. Such a covering is therefore not resistant to abrasion and in particular cannot heavily used walls, which have a high abrasion require stability, or be used as flooring.

The invention is therefore based on the object Process for producing a floor / wall covering of the Generic type in such a way that the Production of an abrasion-resistant floor / wall covering simple way is made possible.

This task is done in a manufacturing process a floor / wall covering of the type described above solved according to the invention in that the porridge before Apply a copolymeric color disperser to the surface sion admixed, and that after drying up the carried porridge on the surface at least one Applying a layer of a pure acrylic dispersion.

The admixture of a copolymeric color dispersion has the great advantage that the applied covering at its Drying hardens so that fibers from the  Floor / wall covering practically only with considerable Remove effort with the help of tools to let. In addition to a copolymeric color dispersion any other water soluble, to solidify the Suitable dispersion mixed with the slurry will.

The application of at least one layer of a pure Acrylate dispersion also causes a surface ver sealing and / or tempering, which is the abrasion resistance of the floor / wall covering additionally increased.

With regard to the application of this layer of pure Acrylate dispersions are the most diverse Aus types of guidance possible. It is advantageous to wear but first a first layer made of pure acrylate dispersion on and then after drying a second layer of pure acrylic dispersion. To this Wise is a particularly good surface seal and / or compensation achieved.

The proportion of the admixture of the copolymeric color dispersion can vary widely in principle. The proportion of the copolymeric color is preferably dispersion between 5 and 60, preferably between 20 and 40, in particular 30 vol .-%. With this share of copolymeric color dispersion becomes a particularly effective and quick curing of the applied floor / wall covering lags achieved.

The most varied come as a pure acrylic dispersion Connections in question. Especially from biological building However, visibility is a water-dilutable and plasticizer  free pure acrylate dispersion of great advantage. On the one hand can be a wall and / or floor covering that with such Surface layer is provided, later easily again are disposed of, on the other hand there is such a waiter surface sealing does not remove any pollutants.

This pure acrylate dispersion is preferably a solution medium-free. However, it is also possible to use solvents Paints, e.g. B. parquet paint or the like seal to use.

The object of the invention is also also through a raw material for a floor / wall cover lay, comprising water-soluble, in a binder bound fibers and an admixture of a co polymeric color dispersion, dissolved.

Such a raw material can be easily transported be and is simple by adding water Way to a pulp-shaped mass that can be processed can be easily applied to a surface.

Especially with a quick and good one Hardening of the raw material processed into a slurry is the proportion of the copolymeric color dispersion between 5 and 60, preferably between 20 and 40, in particular 30% by volume.

Come for the fibers used in the raw material the most diverse starting materials into consideration. So For example, natural fibers such as cotton, Viscose, jute, linen, hemp, flax and cell fibers  and / or synthetic fibers, such as polyamide or polyacrylic fibers and the like can be used.

Methyl cellulose is preferably suitable as a binder or strength.

To achieve aesthetically pleasing effects in particular can also generate in the starting material Admixtures of metallic threads and / or mica components should be provided.

Further features and advantages of the invention are opposed stood of the following embodiment.

It becomes a raw material for a floor / wall covering that water soluble, in a binder, for example Methyl cellulose or starch, including bound fibers Water and an admixture of a copolymer Color dispersion, the proportion of which is approximately 30% by volume, touched.

The resulting porridge is, for example, by means of a trowel (Velcro trowel), using a flow cup pi stole or a pressure boiler device on the surface a floor or a wall.

After the covering applied has hardened, open this one for surface sealing / coating Layer of a water-dilutable, plasticizer-free Pure acrylic dispersion applied. After drying another layer of the same is diluted with water clear, plasticizer-free pure acrylic dispersion gene.  

To make floor / wall coverings particularly aesthetically pleasing can design, the starting material metallic threads and / or mica components are added.

The advantage of the method described above Position of a floor / wall covering is that it easy to carry out - even by a non-specialist - that it allows different design options, that no deformations / faults are possible, as they are for example with a floor made of parquet can occur and that the resulting soil / Wall covering advantageous building biology and building physics has cal properties.
