Abstract
The invention discloses a kind of mineral absorbent-type cat litter and preparation method thereof, be made up of the raw material of following weight portion: graphite powder 4 ~ 5, quartz sand 5 ~ 10, laterite 15 ~ 20, Kaolin 40 ~ 50, waste paper 20 ~ 25, calcium stearate 5 ~ 8, magnetic breeze 8 ~ 15, magnesium oxide 5 ~ 8, medical stone powder 10 ~ 15, binding agent 4 ~ 5 and appropriate water；The present invention is the feature utilizing mineral adsorption ability strong, itself and mixing with soil are used for adsorbing the preparation of the cat litter of pet dung, adequately and reasonably utilize mineral for abnormal flavour and the absorption function of moisture, it is by a peplos structure being made up of laterite, graphite, binding agent simultaneously, laterite is hard the most broken after sintering, it it is good support, this ensures that internal soft form, it is prone to contact with gas, effect is more preferable, graphite has part carbonization completely in the process sintered and leaves micropore so that the specific surface area of cat litter is bigger, and adsorption effect is more preferable.
Description
Technical field
The invention belongs to the Technology field of cat litter, particularly with regard to a kind of mineral absorbent-type cat litter and preparation method thereof.
Background technology
Cat litter is the pet supplies that a kind of consumption is the biggest abroad, is the conventional necessary article of most pet feeding cat family, and additionally in pet shop, pet cat breeding farm etc. will use cat litter, occupies very important status in pet supplies manufacture industry.
In cat culture, of paramount importance progress is exactly the use of cat litter, cat litter in early days is mainly based on incoagulable cat litter, everybody master is to receive cat just, but it is as the continuous progressive of cat litter technology, people are not limited only to receive the simplest, so the most constantly occurring in that present condensation sand, wood sand, and chalazie, bentonite bonded sand etc..
General cat litter is to use paper pulp to break into fine granularity to simulate sandy soil and to provide water absorption, also has the granule using the physical dryness agent such as silica gel.Typically can add the chemical productss such as deodorizer/preservative, cat litter runs into water can condense in bulk, although say be convenient to clean but advise collocation by special leakage shovel, major part cat litter cat can be stained with on foot after stepping on and take that other is local to, therefore please notes and often clears up.
During use into, cat litter is poured cat litter box (a kind of container filling cat litter belongs to pet supplies), auxiliary 7～10cm is thick, it is possible to uses to cat, during cleaning 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 refuse receptacle, just reach to remove feces and the purpose of urine of cat, and remaining cat litter in cat litter box, it is still clean, can be continuing with, after consumption reduces, can continue to add new cat litter and supplement.
Summary of the invention
A kind of mineral absorbent-type cat litter, it is characterized in that, be made up of the raw material of following weight portion: graphite powder 4 ~ 5, quartz sand 5 ~ 10, laterite 15 ~ 20, Kaolin 40 ~ 50, waste paper 20 ~ 25, calcium stearate 5 ~ 8, magnetic breeze 8 ~ 15, magnesium oxide 5 ~ 8, medical stone powder 10 ~ 15, binding agent 4 ~ 5 and appropriate water；
Described binding agent is made up of the raw material of following weight portion: citric acid 3 ~ 5, melamine resin 5 ~ 7, dolomite dust 10 ~ 15, ethyl acetate 3 ~ 5, potassium silicate 2 ~ 3, α sodium olefin sulfonate 4 ~ 6, methyl-silicone oil 4 ~ 5, activated carbon 3 ~ 5 and water 45；Preparation method is: mixing ethyl acetate, methyl-silicone oil and α sodium olefin sulfonate add to water, it is heated to 60 ~ 70 DEG C of stirrings and dissipates 20 ~ 30min one-tenth Emulsion, it is blended into citric acid, melamine resin, potassium silicate, activated carbon and dolomite dust the most successively, it is heated to about 80 DEG C be stirred for into homogenate and get final product, is incubated standby.
The preparation method of a kind of mineral absorbent-type cat litter, it is characterised in that include following step:
(1) waste paper adds the water soaking 8 ~ 10h of 6 ~ 8 times, and after softening, Mechanical Crushing becomes homogenate, obtains lower sediment the most afterwards；
(2) by (1) gained precipitation mixing calcium stearate, magnetic breeze, magnesium oxide and medical stone powder, join in Kaolin, add appropriate water and stir into uniform paste, comminutor preliminary granulation, make the cat litter blank of 3 ~ 4mm particle diameter；
(3) mixing laterite, quartz sand, graphite powder, binding agent and other residual components, add 2 ~ the water stirring of 3 times dissipates 20 ~ 30min and becomes homogenate；
(4) the cat litter blank of (2) being first preheated to 80 ~ 90 DEG C, the homogenate of (3) is then uniformly sprayed to cat litter surface in motion, drum hot blast tentatively dries formation coating, is finally put in the blast furnace of about 250 DEG C baking 20 ~ 30min.
Advantages of the present invention: the present invention is the feature utilizing mineral adsorption ability strong, itself and mixing with soil are used for adsorbing the preparation of the cat litter of pet dung, adequately and reasonably utilize mineral for abnormal flavour and the absorption function of moisture, it has one by laterite simultaneously, graphite, the peplos structure of binding agent composition, laterite is hard the most broken after sintering, it it is good support, this ensures that internal soft form, it is prone to contact with gas, effect is more preferable, graphite has part carbonization completely in the process sintered and leaves micropore, the specific surface area making cat litter is bigger, adsorption effect is more preferable.
Detailed description of the invention
Embodiment 1:
A kind of mineral absorbent-type cat litter, it is characterised in that be made up of the raw material of following weight portion: graphite powder 5, quartz sand 8, laterite 15, Kaolin 50, waste paper 20, calcium stearate 8, magnetic breeze 10, magnesium oxide 5, medical stone powder 10, binding agent 4 and appropriate water；
