Abstract
The invention discloses a coated environment-friendly cat litter and a preparation method thereof. The coated environment-friendly cat litter is prepared by the following raw materials in the weight part: palm oil 10-15, palm leaf 6-8, tea branch 15-20, polyving akohol 2-3, red clay 15-20, city lime sludge 30-45, ethyl alcohol 5-10, waste newspaper 15-20, kieselguhr 30-40, silica sand 5-9, binder 40-45 and suitable amount of water. The preparation method comprises the steps of boiling the palm leaf and tea branch, and grinding to form slurry, extracting the aroma compound in the slurry, coating and immobilizing by the polyving akohol and palm oil, enveloping after mixing with a backing material. The wood fiber structure of the crushed tea tree has the function of framing and fixing cat litter particles, and has the effect of adsorption and sterilization. The coated environment-friendly cat litter is natural and pollution-free, the aromatic ester compound therein is slowly released, the air quality is improved, and the using is convenient.
Description
Technical field
The invention belongs to the technology field of cat litter, be specifically related to a kind of cladded type environmental protection cat litter and preparation method thereof.
Background technology
Cat litter is the very large pet supplies of a kind of consumption abroad, and be the conventional necessary article of most pet feeding cat family, in addition in pet shop, pet cat breeding farm etc. all will use cat litter, manufactures in industry occupy very important status at pet supplies.
In cat culture, of paramount importance progress is exactly the use of cat litter, early stage cat litter is mainly based on incoagulable cat litter, everybody master is to receive cat just, but along with the continuous progress of cat litter technology, it is simple like this that people are not limited only to storage, so constantly there is again present condensation sand, wooden sand, and chalazie, bentonite bonded sand etc.
General cat litter uses paper pulp to break into fine granularity to simulate sandy soil and to provide water imbibition, also has the particle using the physical dryness agent such as silica gel.Generally can add the chemical products such as deodorant/preservative, cat litter runs into water can condense into block, although be convenient to cleaning but suggestion collocation by special leakage shovel, to be stained with after most of cat litter cat steps on pin and to take that other is local to, therefore please noting frequent cleaning.
During use, cat litter is poured into cat litter box (a kind of container filling cat litter belongs to pet supplies), auxiliary 7 ~ 10cm is thick, just can use to cat, during clean cat litter box, with cat litter shovel (specific purpose tool belongs to pet supplies), those cakey blocks are shoveled out from cat litter, lose into dustbin, just reach and remove the ight soil of cat and the object of urine, and remaining cat litter in cat litter box, be still clean, can continue to use, after consumption reduces, can continue to add new cat litter and supplement.
Summary of the invention
A kind of cladded type environmental protection cat litter, it is characterized in that, be made up of the raw material of following weight portion: palm oil 10 ~ 15, palma 6 ~ 8, tea tree branch 15 ~ 20, polyvinyl alcohol 2 ~ 3, laterite 15 ~ 20, city filter mud 30 ~ 45, ethanol 5 ~ 10, old newsprint 15 ~ 20, diatomite 30 ~ 40, silica sand 5 ~ 9, binding agent 4 ~ 5 and appropriate water;
Described binding agent is made up of the raw material of following weight portion: methyl methacrylate 6 ~ 8, ethanol 3 ~ 4, sodium lauroyl sarcosine 3 ~ 5, aluminium dihydrogen phosphate 1 ~ 2, sodium bicarbonate 4 ~ 6, fresh pine sawdust 10 ~ 14, fresh pine bark 8 ~ 12, white lime 5 ~ 7 and appropriate water; Preparation method: (1), by fresh pine sawdust and pine bark mixing white lime, add the water boil of 4 ~ 6 times and soak 10 ~ 12h, then ball milling 20 ~ 30min is to homogenate, centrifugal rear removal bottom sediment, stirs into emulsion by after supernatant and floccule mixed carbonic acid hydrogen sodium; (2) ethanol is added the water dilution of 8 ~ 10 times, then add methyl methacrylate, sodium lauroyl sarcosine and aluminium dihydrogen phosphate, stir and disperse about 20min and dissolve, the emulsion be finally blended into described in (1) stirs and get final product.
A preparation method for cladded type environmental protection cat litter, is characterized in that, comprises following step:
(1) mix palma and tea tree branch, add the soak by water 50 ~ 60min of 4 ~ 5 times, be milled to homogenate;
(2), in the homogenate mixing of palm oil, polyvinyl alcohol and ethanol being added to described in (1), stir and to disperse after 30 ~ 40min uniformly emulsion;
(3) mix city filter mud, silica sand and diatomite after waste newspaper flour being broken into slag, the emulsion admixed described in (2) is suitably watered and makes water content about about 30%, in granulator granulation, makes the cat litter particle of particle diameter 3 ~ 5mm;
(4) mix laterite, binding agent and other residual components, the water adding 2 ~ 3 times stirs into homogenate, is heated to 80 ~ 90 DEG C, is sprayed on the cat litter particle surface of (3) in coating machine, finally in the baking oven of about 220 DEG C, toasts 80 ~ 100min.
Beneficial effect of the present invention: the present invention is by decocting palma and tea tree branch, regrind and make homogenate, refine the aromatic compounds utilized wherein, then by polyvinyl alcohol and being coated and fixed of palm oil, coating after mixing with bed material, wood fibre structure after tea tree pulverizing not only plays the effect of framework and stable cat litter particle, also there is effect that absorption is degerming, natural pollution-free, fragrant compound slow releasing wherein, improve air quality, easy to use.
