DE3816225A1 - Odour- and moisture-binding litter and process for its production - Google Patents

Abstract

For the production of an odour- and moisture-binding scatter composition (litter) for small animals, a cellulose-containing material, as wet substance, is mixed with at least one fine-grained substance which is capable of capillary action and has a particle size of less than 0.5 mm, preferably less than 0.1 mm, in a ratio by weight of from 90 : 10 to 20 : 80, preferably from 70 : 30 to 55 : 45.

Description

The invention relates primarily to an olfactory and moisture-binding scattering agent, especially for small animals with a cellulose-containing material.

It is known to produce a cat litter from unprinted waste paper - that is, a cellulose-containing material - with the addition of an odorant. This scattering agent is sold in the form of unevenly sized, irregular particles with a diameter of 0.1 cm to about 1 cm and is only accepted by cats if a decisive odor overlay gives the animal a certain proximity to the earth. EP 01 15 898 describes the use of a cellulose waste sludge and an inorganic pigment in a weight ratio of 20-50% by weight of fibers and the use of a cellulose waste sludge and an inorganic pigment in a weight ratio of 20-50% by weight of fibers and 50-80% by weight. % Pigment known; the pigments only serve as fillers and do not participate in absorption.

The invention has for its object a sprinkler type mentioned above and a process for its manufacture to create, in which by admixing certain Fabrics not only increases moisture and odor binding but also the acceptability of the small animals.

The object is achieved in that the cell according to the invention Substance-containing material as a wet substance with at least one Capillary-capable small-grain material with a grain size up to 0.5 mm, preferably up to 0.1 mm, in a weight ratio from 90:10 to 20:80, preferably 70:30 to 55:45 mixed is.  

Capillary-capable small-grained substances, such as those to be used according to the invention, include those materials - primarily from the mineral sector - which have a relatively large inner surface and thus a high binding capacity.

Such materials are already in different contexts settings known. For example, Sepiolite and attapulgite too mention, which, however, have a carcinogenic effect. Furthermore, not only pumice stone granulate is a natural mineral, but also gas concrete granulate as an artificial mineral for such a purpose has been used. It is also true known that the pulp or pumice Granules are particularly environmentally friendly substances, however these materials were mostly used in each case alone or with the addition of neutral fillers, so that the combinatorial effect of the invention Mix could not be achieved.

The pulp-containing material can be made from cellulose flour or closed waste paper. However, it is particularly preferred Paper capture fabric with a moisture content of 50-60%. Such a paper catcher falls e.g. in the preparation of from hygiene paper on and is usually used in the farmer shaft used; it is also ecologically harmless.

The capillary-capable substance can be earth, limestone flour, wood flour, Bentonite or clay flour. However, it is particularly preferred Pumice stone flour with a moisture content of at most 30%. When using this material and paper catch in both cases are waste products, which are now jointly supplied for the above-mentioned purpose will.  

Pumice stone powder is a dust-like product which is used in the Processing of pumice material occurs and a grain size of has less than 0.2 mm.

To further improve the spreading agent can be added Soil, odorant or methyl cellulose may be provided.

To promote tradability can be used in manufacturing of the litter material are proceeded so that the cell material containing a capillary material standing mixture compacted, tableted or pelleted becomes. To treat the mixture is preferably a Screw or roller compactor or tablet press or a pearl plate and / or a hot air dryer intended.

By the post-treatment of the mixture just described the binding capacity of the grit due to the increased Degree of dryness increased even further.

The sprinkle can not only be used for golden hamsters, white mice, Guinea pigs are used, but especially for Cats and finally where there is an absorbent effect for liquids and gases, e.g. also at leaking heating oil or other oil derivatives.

Usually, however, the appropriate sprinkling agents are found in so-called Use litter boxes where they are for suction moisture and preventing odors are used extensively in living rooms.

The following are examples of specifying the composition and the Production of the grit according to the invention.

example 1

1 kg limestone flour with a moisture content of approx. 20% is mixed with 9 kg of digested waste paper.

The mixture obtained is ge in a hot air dryer dries so that a powdery to small-grain Pro product is received.

This dried end product is sold packaged.

Example 2

5 kg of wood flour is mixed with 5 kg of cellulose flour approx. 30 vol .-% water mixed. The addition of water is required Lich because the two starting materials are too dry.

After the mixture has been prepared, it is compacted in a screw compactor, so that sausage-shaped dry particles are formed that have a final moisture content of approx. Have 30%. Then it is ge with a hot air dryer dries until a final moisture content of approx. 2 vol.% is enough.

This material is put on the market in packaged condition brought.

Example 3

4.5 kg pumice stone flour with a moisture content of 20% comes with 5.5 kg of paper trap with a moisture just mixed 50-60%. This paper catcher is that Waste product in the production of hygiene paper, has one light gray color and a chunky consistency.  

The product obtained has a gray-brown color and is crumbly. To increase the usability on the market there is a post-treatment with a tableting press, see above that the final product was launched in tablet form after it has reached a moisture content of 2 vol. was dried.

Example 4

8 kg of pumice stone flour are mixed with 2 kg of cellulose flour, about 30 vol .-% water are added.

The mixture obtained is applied in a hot air dryer dries so that the final moisture content is approx. 2%. The granular to chunky end product is packaged and brought on the market.

When using pumice stone powder or limestone powder on the one hand and paper catcher on the other hand - is starting at a ratio of 6: 4 to 8: 2 - the processability the mixture by adding water or liquid Lich improved.
