Abstract

The invention discloses carbonized corn straw cat litter and a preparation method thereof. The carbonized corn straw cat litter is prepared from the following raw materials in parts by weight: 40 to 50 parts of corn straw, 10 to 15 parts of corn cob, 10 to 15 parts of clay, 20 to 28 parts of sewage sludge, 4 to 6 parts of quartz sand, 2 to 3 parts of purple powder, 6 to 8 parts of ammonium nitrate, 4 to 5 parts of binding agent and a proper amount of water. The straw and urban sludge are used as raw materials to be prepared into efficient environment-friendly cat litter with high adsorption, waste materials in living can be fully used, the straw is prevented from being burnt, and the sludge is taken from earth deposited in sewers, so that the environment is protected. Specifically, the straw is prepared into powder and then is carbonized at high temperature to be prepared into carbon materials with adsorption effects, and ammonium nitrate particles, which are easy to decompose by heating, of the particle sizes of 40 meshes are matched, so as to prepare porous cat litter with strong adsorption. The carbonized corn straw cat litter has the advantages of environmental friendliness, wide raw material sources and economy and has the sustainable development potential.

Description

A kind of charing maize straw cat litter and preparation method thereof

Technical field

The invention belongs to the technology field of cat litter, specifically a kind of charing maize straw 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 charing maize straw cat litter, it is characterized in that, be made up of the raw material of following weight portion: maize straw 40 ~ 50, corncob 10 ~ 15, clay 10 ~ 15, sewage sludge 20 ~ 28, quartz sand 4 ~ 6, lac powder 2 ~ 3, ammonium nitrate 6 ~ 8, binding agent 4 ~ 5 and appropriate water;

Described binding agent is made up of the raw material of following weight portion: sodium metasilicate 3 ~ 5, white carbon 4 ~ 5, land plaster 10 ~ 14, isopropyl alcohol 4 ~ 6, aluminium chloride 1.5 ~ 3, fatty alcohol-polyoxyethylene ether 2 ~ 3, polyvinyl alcohol 1 ~ 2, water 30; Preparation method is: by sodium metasilicate and polyvinyl alcohol mixing, add water and heat stirring and dissolving, then mixed white carbon, land plaster and aluminium chloride pulvis is blended into, stirring 20 ~ 30min disperses evenly, finally add isopropyl alcohol and fatty alcohol-polyoxyethylene ether, stir into uniform clay after mixing and get final product.

Carbonize a preparation method for maize straw cat litter, it is characterized in that, comprise following step:

(1) first by maize straw and corncob mixing, add the slurry that the water of 3 ~ 5 times and quartzite sand grind become more than particle diameter 40 order, dewatered drying obtains pulvis;

(2) put into Muffle furnace by after described to (1) pulvis sealing, temperature 600 ~ 700 DEG C carries out heating charing 5 ~ 7h, obtains carbonizing production after being cooled to room temperature, and mixed clay, sewage sludge and lac powder, add water furnishing pasty state, water content about 30%;

(3) drying crystalline be ground into the particle of 40 order sizes again after ammonium nitrate being dissolved in water, hybrid adhesive and other residual components join in the thickener of (2), and stir and make particle disperse evenly, granulation, makes the cat litter blank of 3 ~ 5mm particle diameter;

(4) cat litter particle prepared by (3) is toasted 30 ~ 40min under more than 200 DEG C high temperature, ammoniumnitrate prill in gasification particle also leaves hole, after completing.

Beneficial effect of the present invention: the present invention is a kind of high adsorption high-efficiency environment friendly cat litter utilizing stalk and municipal sludge to make for raw material; make full use of the obsolete material in life; avoid burning straw; mud takes from the earth of sewer deposition more; protection of the environment; after specifically stalk being made pulvis, high temperature carbonization makes the carbonaceous material with adsorption effect; coordinate the labile ammoniumnitrate prill that is heated of particle diameter 40 order size; make a kind of cellular and adsorb cat litter by force; environmental protection and raw materials wide material sources, economy, have the potentiality of sustainable development.
