Abstract
The present invention provides a toilet sand used for toilet for animals, suppressing occurrence of odor emitted by excrement left in the toilet sand and to a toilet using the sand. The toilet sand for animals is constituted of a plurality of particulates and is equipped with first particulates having water repellency and second particulates having water-absorbing properties.
Description
Technical field
The present invention relates to a kind of animal litter that is used as animal lavatory bedding and padding such as cat or dog.
Background technology
As animal toilets such as the cat of indoor feeding or dogs, in plastics system box-shaped container, be placed with the sanitary sand that constitutes by the shot-like particle that is known as " cat litter " and use.The excretas such as urine that animal drains are absorbed by such sanitary sand.Raising the chief commander is removed from container, and replenishes new sanitary sand according to having removed part with ight soil etc. by the sanitary sand of urine or fecal pollution.But cat has after drainage the habit that stirs sanitary sand with claw, and the sanitary sand that is attached with urine or ight soil sometimes will be attached on the claw.And,, be difficult to only remove contaminated part fully because contaminated sanitary sand is come by diffusion.
The sanitary sand that is used for above-mentioned lavatory has the zeolite or the river sand of mineral substance, perhaps absorbs liquid and solidifies bentonite, solidifies the granular cellulose of back formation such as comminution pulp etc.But zeolite or river sand etc. does not absorb urine, and absorptivity such as bentonite or paper pulp is poor in addition, does not also have deodorizing capability.And the animal particularly excreta stench of cat is strong, is equipped with the indoor stink that all filling the air in lavatory, finally can produce unplessantness displeasure.
As the means that address the above problem, a kind of sanitary sand (example: referenced patent document 1) that is constituted, had strong deodorizing power and absorptivity by the water-fast silica gel of porous matter is arranged.In addition, also have in sanitary sand, to use to have hydrophobic material, share the imbibition pad that absorbs moisture such as urine simultaneously, thereby suppress the generation (example: referenced patent document 2) of stink.
Patent documentation 1: specially permit No. 2766632
Patent documentation 2: the spy opens flat 10-229768 communique
But the sanitary sand of record in the patent documentation 1 is in order effectively to absorb urine with the surface area that reduces sand with the space through reducing particle diameter, the little 2mm to 6mm that arrives of its particle diameter.And in order moisture content to be established low to increase infiltration rate and maximum absorption, moisture content is adjusted into 90 ℃ to 120 ℃ down dry backs below 3 weight %.Like this, above-mentioned sanitary sand infiltration rate is fast, and the urine of drainage etc. can be by fast Absorption.But the silica gel that has absorbed a large amount of urines remains in the container of lavatory very unhygienic, and is the reason that produces stench.
In addition, the shot-like particle of the formation sanitary sand of record is owing to no water imbibition in the patent documentation 2, and urine etc. can't remain in the shot-like particle surface through shot-like particle, produce stench after these remaining urine corruption, and this also is a problem.Further, can not pass through sanitary sand owing to can't form moisture in the ight soil of current etc. on a small quantity, the stink of ight soil is also possible residual.Therefore, being necessary when pet drains, to abandon the contaminated part of sanitary sand at every turn, or just sanitary sand all being changed once in 1,2 weeks, in addition, is not sanitary sand, and the imbibition pad also must be replaced by new, has so just produced the problem of a large amount of rubbish.
