Description

15th

The invention relates to a cleaning agent, in particular for cleaning textiles and textile floor coverings, and a process for its production.

The cleaning of textiles, especially the cleaning of permanently installed textile floor coverings still causes considerable difficulties. To z. B. the textile floor covering is not too wet make, and to soften the transitions between the cleaned and not cleaned areas hold, and to protect the colors and fibers is it has been proposed that cleaning agents apply as a foam. Such detergents are also known under the name "dry foam", jo These foams, which mostly consist of an aqueous Cleansing liquids, which contain emulsifiers and foam stabilizers, are based on mechanical Ways, and / or by means of a liquid propellant, such as. B. Frigen, produced "

These foams are very unstable and collapse under pressure and movement, as well as through the release of moisture. The foam volume applied is reduced considerably. A mechanical or manual foam movement, respectively, is required to absorb dirt Foam circulation is desirable so that dirt is removed from all of the applied foam can be included.

There is a disadvantage of so-called dry foams, which are actually liquid foams also in the fact that, when they collapse, the goods to be cleaned become too strong in an undesirable manner wet.

The object of the invention to provide a cleaning agent that does not have the known disadvantages, and v 'that can be easily manufactured and applied to the items to be cleaned.

The object of the invention also includes designing a cleaning agent in such a way that it is a good one Has a sliding effect, has a large inner surface and can therefore absorb a lot of dirt.

This object is achieved according to the invention in that the cleaning agent in addition to one per se known cleaning liquid consists of hollow microbeads, the thin shells of which are made of a thermoplastic material see plastic material are formed.

The hollow microbeads preferably consist of polyvinylidene chloride copolymer. You own a diameter of 0.01 to 0.4 mm. The membrane shell of the hollow microbeads is elastic and smooth, so that μ they can be easily moved over the item to be cleaned without collapsing. Through the used Liquid loosens the dirt from the material to be cleaned and from the large inner surface of the "quasi-foam" recorded.

The bulk volume / bulk weight of the dry Micro hollow pearls (without admixture of liquid) is between 0.01 and 0.18 tfg / uter,

Due to the stability of the cleaning agent After application, considerable amounts of dirt can be picked up by movement without there is a risk that the foam-like detergent will collapse and damage the detergent thus consists according to the invention of a mass, which is made up of hollow microbeads and a liquid or pasty substance and optionally other substances

The foam-like consistency of the cleaning agent is very stable against mechanical stress, Dehumidification and chemicals.

In general, the detergent is in volume between 10 and 85% made of hollow microbeads.

Another advantage of the cleaning agent according to the invention is that the hollow microbeads themselves are flame retardant and in connection with cleaning agents such. B. water or chlorinated hydrocarbons lead to a non-flammable cleaning agent.

All known liquid or pasty active substances are used as cleaning active substances Question. In particular, those that dry quickly, that is, have a low boiling point, such as. B. low Alcohols, cleaning gasoline, chlorinated hydrocarbons and the like. - Of course, the liquid or pasty substance can also be a solvent mixture or an emulsion. For some uses it is water with cleaning additives is also an advantage.

The hollow microbeads or the sheaths of the hollow microbeads can be made of any desired thermoplastic Kuns! -toff be formed, in addition to polyvinylidene chloride copolymer those made of polyvinyl chloride copolymer are also well suited.

In general, 1.5 liters of hollow microbeads are used to produce the cleaning agent mixed with 42 to 580 grams of liquid

The inventive method for producing the cleaning agent is characterized in that the hollow microbeads are formed in situ in the cleaning liquid by means of heat. One A description of such hollow beads and their formation can be found in the magazine "Modem Plastics" 1969, August, page 55.

The invention is further illustrated by an example explained: In 4.5 liters of water, which is a dirt-dissolving Contains active ingredient, 90 grams of polyvinylidene-Chloriu-Copolymerisat compact particles Then the mixture is heated to a temperature above plus 55 ° C. Form thereby the hollow microbeads in the cleaning liquid with a considerable increase in volume. The so The resulting »quasi-foam« is applied to and on the item to be cleaned in any way emotional. Then the "quasi-foam" with the absorbed dirt is used in any way, e.g. B. by Vacuuming or brushing away.

In the context of the invention it is also possible to use the liquid and the thermoplastic propellant-containing To continuously assemble and heat compact plastic particles by means of a device, and lay the foam straight onto the item to be cleaned.
