Description

The invention relates to a sand composition for the cat toilet, for use in the field of veterinary hygiene.

Several compositions used for the cat toilet are known in the art. Of the components of these compositions, bentonite is most often used as an absorbent material, which also solves the problem of odorization. For the absorption of odors, activated carbon is also used (CA 2552216).

Some compositions contain plant fibers (HK1065679), and other compositions are paper and molecular zeolites (HK 1041174).

US patent 6662749 has the paper as an absorbent component, and in other patents various solids and a liquid substance are used as an absorbent for odor. US Patent 2003-200936 uses silica gel as a highly absorbent material, and US Patent 6029603 uses a mixture of gypsum and zinc sulphate for this purpose. US Pat. No. 630,8658 uses expanded, naturally occurring aggregates from volcanic rocks (perlite, vermiculite), and to reduce odor, ester compounds of parabenzoic acid (paraben, E215, E216, E218).

A number of other substances are used for disinfection such as: sodium perborate (WO 8 150 251), camphor (WO 00053001), carboxylic acid, alcohol and carbonyl phenol (EP 1020112).

U.S. Patent 4607594 has a granular absorbent composition, useful as a hygienic blanket for pets. This composition comprises a mixture of cellulose and clay absorbent particles, volcanic rock absorbing inert granules, which are treated with a neutralizing agent, selected from: carbonates, bicarbonates or hydrogen phosphates, including sodium carbonate, calcium carbonate, bicarbonate of sodium, calcium bicarbonate, calcium phosphate dihydrogenate and mixtures thereof; at the same time, it is specified that the absorbent particles are selected from a group consisting of bentonite, montmorilonite, kaolin, atapulgite and their mixtures, in the form of pearls.

These compositions have the disadvantage that they have high density (such as those containing bentonite, baritine), and others contain toxic additives, if their use is long lasting.

The technical problem, which is solved by the present invention, is to obtain an improved sand composition for the cat toilet.

The sand composition for the cat toilet, according to the invention, consists in that it consists of:

- absorbent material, resulting from wastes of dry working forms from the ceramic industry, consisting of 75% molding plaster, 5% expanded pearl with a density of 60 kg / m ³ , 9.5% kaolin in bubble wrap with a minimum of 85% kaolinite, 0.5-6.5 mm granulation and minimum 75% liquid absorption power, covered with 5% activated bentonite;

- 5% neutralizing material, consisting of technical sodium bicarbonate at a concentration of at least 95%;

- 0.5% disinfectant material, made up of 98% urea peroxide, the percentages being expressed by weight.

The composition according to the invention has the following advantages:

- makes better use of plaster waste;

- it has high absorption power of liquids;

- is light, having a low density;

- it has as disinfectant the active oxygen, resulting from the decomposition of the perogen;

- does not contain toxic substances;

- is well supported for use.

In the figure a diagram of the flow of the preparation operations of composition 1 for the cat toilet is shown.

The sand composition for the cat toilet, according to the invention, uses as raw material 3 wastes of working forms used in porcelain factories.

The raw material consists of molding plaster (CaSiO ₄ .1 / 2 H ₂ A concentration of 5 minimum 75%) in a volumetric proportion of 75%, expanded pearlite (expanded volcanic glass with density 60 kg / m) in a volumetric proportion of 5 %, kaolin (with kaolinite of at least 85%) 7 of barbotine, in a volumetric proportion of 9.5%.

During use in production, working forms absorb water from the kaolin bubble; 9 after a few uses the molds are impregnated with kaolin (kaolinite of at least 85%) from the bubble, reducing the water absorption power below 95% of its own weight, becoming 11 such wastes; they are partially used in the cement industry (due to the high percentage of kaolin) and are ideal for use in sand compositions for the toilet of 13 cats, as they contain an absorbent material (plaster, pearlite) and a natural deodorizing material (pearlite and kaolin). . 15

Example of realization

- waste with natural moisture (sun drying) of up to 30% is crushed 17 (grain size up to 12 mm);

- on the conveyor line the plaster is separated from other possible materials (the remains from 19 plastic columns);

- 3 kinds are placed and obtained: about 10% <0.5 mm, about 80% 0.5-6.5 mm, about 21 10%> 6.5 mm;

- the 0,5-6,5 mm batch is humidified with a technical sodium bicarbonate solution with 23 concentration of 50% to 50% humidity, after which it is covered with 5% activated bentonite powder; In the mixing process bentonite pieces of about 1 mm may also result; After drying, it is added with urea peroxide and packaged;

- the <0.5 mm lot is re-used in combination with plaster and water, obtaining parallelepiped pieces that are reintroduced into the stream;

- the sort> 6.5 mm is ground on a specialized roller, then the flow is resumed with the operation of 29 sieves;

- the quality control was performed according to the company standard; 31

- the tests for the approval of the product, as well as the subsequent quality checks were carried out by the Institute of Research of Biological Products and Medicinal Products for Veterinary Use 33.

finally, a composition with the following characteristics is obtained: 35
