Description

Technical Field

[0001] This invention relates to the field of pet cleaning products technology, specifically to a strip-shaped bentonite cat litter. Background Technology

[0002] Currently, the common types of cat litter on the market include: traditional strip-shaped plant litter, granular cassava cat litter, traditional bentonite ball litter, and crushed bentonite mineral litter. Among them, traditional strip-shaped plant litter and cassava cat litter are insufficient in terms of odor control; traditional bentonite ball litter is prone to generating dust; and crushed bentonite mineral litter is too dependent on the mineral source, resulting in inconsistent quality.

[0003] Of the above products, strip-shaped plant litter has relatively weak resistance to mold and odor during use; while cassava cat litter and crushed bentonite cat litter offer a good feel underfoot, they are particularly prone to being tracked out by cats during use. All products currently on the market have certain drawbacks, and the purpose of this invention is to propose a product that solves these problems. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a strip-shaped bentonite cat litter that has good water absorption, a comfortable feel underfoot, and is economical in terms of usage and processability.

[0005] To achieve the above objectives, the present invention provides a strip-shaped bentonite cat litter comprising the following components by weight percentage: Bentonite 86%~95.5% Polyaluminum chloride 1%~3% Carboxymethyl cellulose 0.5%~1% Calcium carbonate 0.3%~1% Baking soda 0.5%~2% Guar gum 1%~5% Soda ash 0.5%~0.8% Nanospheres 0.3%~0.5% Microcrystalline cellulose 0.1%~0.2% Quick-drying agent: 0.3%~0.5%.

[0006] Furthermore, the weight percentage of bentonite is 91.05%, the particle size of bentonite is 300 mesh, the colloidal value of bentonite is ≥300mL, the swelling capacity of bentonite is ≥28mL / g, and the water absorption rate of bentonite is ≥250mL.

[0007] Furthermore, the polyaluminum chloride has a weight percentage of 1%, is a white food grade, and has an effective substance content of 30%.

[0008] Furthermore, the weight percentage of carboxymethyl cellulose is 0.7%, the carboxymethyl cellulose is food grade, and the viscosity of the carboxymethyl cellulose is ≥1200 CPS.

[0009] Furthermore, the calcium carbonate content is 0.7% by weight, it is light calcium carbonate, the particle size is 400 mesh, and the whiteness is 98%.

[0010] Furthermore, the weight percentage of baking soda is 1.2%, which is food grade and has a particle size of 300 mesh; the weight percentage of soda ash is 0.6%, which is food grade and has a particle size of 300 mesh; the weight percentage of microcrystalline cellulose is 0.15%, which is food grade and has a particle size of 300 mesh; and the weight percentage of quick-drying agent is 0.3%.

[0011] Furthermore, the weight percentage of guar gum is 3%, and the viscosity of guar gum is ≥6500 CPS.

[0012] Furthermore, the nanospheres have a weight percentage of 0.3%, are monodisperse polystyrene nanospheres, have a solid content of 20%, and have a diameter of 0.5 μm to 2 μm. Bentonite is used as the base material. Polyaluminum chloride enhances the plasticity and hydration capacity of bentonite. Carboxymethyl cellulose reduces filtration loss. Calcium carbonate increases the hardness of bentonite. Baking soda enhances the deodorizing function of bentonite. Guar gum increases the viscosity of bentonite. Soda ash increases the water absorption of bentonite.

[0013] The nanospheres are monodisperse polystyrene nanospheres, also known as PS nanospheres, from Cresray Technology (Shanghai) Co., Ltd., which can be used to manufacture shaped particle void structures.

[0014] Microcrystalline cellulose enhances the dispersion properties of bentonite after water absorption.

[0015] The quick-drying agent used is SlurralEH 31 quick-drying agent from Shanghai Zecheng Chemical Co., Ltd., which can accelerate the drying speed of the particles after absorbing urine.

[0016] This invention also proposes a method for producing strip-shaped bentonite cat litter, characterized by comprising the following steps: S1: Preparation: Measure and mix the raw materials thoroughly, add water and stir evenly; S2: Granulation. The stirred mixture is fed into a rotary granulator via a screw conveyor to granulate the mixture, resulting in elongated granules with a particle size of 0.8 mm to 1.2 mm. S3: Drying. Place the prepared elongated granules into a kiln drying oven and dry at 160℃ for 0.5h, or dry at 180℃ for 3h in a regular oven. S4: Vacuum pack the dried, long strip-shaped granular cat litter to obtain the finished product.

[0017] This invention provides a strip-shaped bentonite cat litter granulated using a premixing method. Its advantages far outweigh those of simply modifying the particle surface. The mixed particles have more uniform and stable functionality, ensuring the long-lasting effectiveness of the cat litter during use. The rotary granulator process allows for the production of finished products with an extreme particle diameter (≤1mm), ensuring uniform particle hardness and size, and controllable particle size. The compressed particles are more compact, preventing the generation of more dust due to crushing or friction, thus ensuring that dust does not increase over long-term use. The hard particles also conform to the cat's paws, making it more appealing to cats. The ultrafine particles have excellent encapsulation properties for cat excrement and urine, resulting in more litter consumption. The above process also maintains the original deodorizing properties of bentonite particles, making the product superior to traditional bentonite cat litter and traditional plant-based cat litter.

[0034] Example 5: Production of strip-shaped bentonite cat litter, including the following steps: S1: Preparation: Take the raw materials and mix them thoroughly. First, put 86kg of bentonite, 3kg of polyalumina, 1kg of carboxymethyl cellulose, 1kg of light calcium carbonate, 5kg of guar gum, and 0.5kg of PS nanospheres into a screw mixer. Set the speed to 40r / min and spray 10kg of water at the same time. Mix thoroughly for 10min. Then, add 2kg of baking soda, 0.8kg of soda ash, and 0.2kg of microcrystalline cellulose into 10kg of pure water in sequence and stir for 1min until there are no solid substances. Finally, add 0.5kg of quick-drying agent EH31 and spray the entire solution into the screw mixer. Set the speed to 60r / min and mix for 20min. S2: Granulation. The stirred mixture is fed into a rotary granulator via a screw conveyor.

Alternatively, dry in a regular oven at 180℃ for 3 hours. The moisture content of the finished product should be ≤5%. S4: The dried finished product is filtered for dust by a vibration dust removal device and then vacuum-packed to obtain the finished product.

[0035] Individual finished product granules from Examples 1-5 were placed in water and their dissolving state was observed after 1 minute. Figure 2 As shown, from left to right, these are individual cat litter pellets from Examples 1 to 5, and the records are shown in Table 1.

[0036] Table 1

[0037] As shown in the figure, the absorption rate of the finished products in water varies slightly. Example 3 is the best example, but all five examples can be used normally as cat litter.

[0038] The effect of particle size on the absorbency of cat litter was tested through the following experiments: Based on Example 3, in the granulation process of step S2, cat litter was prepared using molds with pore sizes of 1 mm, 1.5 mm, and 2.0 mm, respectively. The finished products were dried at 160°C to obtain test samples with particle sizes of 1 mm, 1.5 mm, and 2.0 mm.

[0039] Test method: Take 10ml of water with a syringe, squeeze it into the cat litter, let it stand for 30 seconds, take out the clumped cat litter, weigh it 3 times, and the results are shown in Table 2.

[0040] Table 2

[0041] This leads to the conclusion that the finer the particle size, the less cat litter is needed to absorb the same amount of water. Smaller particle size means less litter is used.

[0042] The effect of nanospheres on the pore structure of cat litter particles was tested using the following methods: Based on Example 3, in step S1, the amount of PS nanospheres was adjusted to 0, 100g, 300g, 500g, and 700g to obtain test samples with different PS nanosphere contents.

[0043] Test method: Samples with 0% PS nanosphere content were numbered 1, 100g sample was numbered 2, 300g sample was numbered 3, 500g sample was numbered 4, and 700g sample was numbered 5. One to two cat litter samples of sizes 1 to 5 were taken and placed in an empty bowl with purified water. The time was recorded from the moment the cat litter sample particles entered the water until they began to dissolve noticeably. The time was recorded as t1, and the time it took for the cat litter particles to completely dissolve was recorded as t2. The results are shown in Table 3.

[0044] Table 3

[0045] As shown in Table 3, the addition of PS nanospheres significantly affects the water absorption rate of cat litter. Samples without added PS nanospheres exhibit a flat and dense cross-section, with a compact internal structure. When these particles are submerged in water, water cannot easily penetrate them, resulting in a very slow dissolution rate. Figures 3-6 As shown, the surface of the sample particles after adding PS nanospheres exhibits numerous spherical voids, and a distinct microporous structure is also visible in the cross-section. The nanospheres act as fillers on the surface and inside of the cat litter particles, retaining their original cavity structure after drying, thus increasing the specific surface area. When the cat litter particles are soaked in water, the surface and internal voids significantly enhance the water absorption rate of the bentonite. Regarding the dosage, when the dosage exceeds 500g, the increase in the product's water absorption rate becomes relatively small.

[0046] The effect of microcrystalline cellulose on the water absorption rate of cat litter was tested using the following methods: Based on Example 3, in step S1, the amount of microcrystalline cellulose was adjusted to 0, 100g, 150g, 200g, and 250g to obtain test samples with different microcrystalline cellulose contents.

[0047] Test method: Samples with 0% microcrystalline cellulose content were numbered 1, 100g sample was numbered 2, 150g sample was numbered 3, 200g sample was numbered 4, and 250g sample was numbered 5. One to two cat litter samples of sizes 1 to 5 were taken and placed in an empty bowl with purified water. The time was recorded from the moment the cat litter sample entered the water until it began to dissolve noticeably. The time was recorded as t1, and the time it took for the cat litter sample to completely dissolve was recorded as t2. The results are shown in Table 4.

[0048] Table 4

[0049] The addition of microcrystalline cellulose has a significant impact on the water absorption rate of cat litter, such as... Figure 7 As shown, the sample without added microcrystalline cellulose has a compact particle cross-section with small gaps, making it difficult for water to penetrate into the particle interior. Figure 8 As shown, the cross-section of the sample particles after the addition of microcrystalline cellulose exhibits a large number of voids and cross-sections, increasing the specific surface area and thus enhancing the water absorption rate of bentonite. Figure 9 As shown, the changes in the dissolution of sample particles after adding microcrystalline cellulose into water are visible. The left side shows the particles immediately after being added to the water, and the right side shows the particles after dissolution. Figure 10 As shown, the left side is the sample without added microcrystalline cellulose, and the right side is the sample with 150g of added microcrystalline cellulose. It can be seen that the addition of microcrystalline cellulose has a positive effect on the water absorption speed and disintegration of cat litter.

[0050] As can be seen from the data in Table 4, when the amount added is higher than 150g, the effect of microcrystalline cellulose on the increase of the product's water absorption rate is relatively small.

[0051] The effect of quick-drying agents on the clumping effect of cat litter was tested using the following methods: Based on Example 3, in step S1, the amount of quick-drying agent was adjusted to 0, 150g, 300g, 450g, and 600g to obtain test samples with different quick-drying agent contents.

[0052] Test Method: Samples with 0% quick-drying agent content were taken as follows: Sample 1 (150g), Sample 2 (300g), Sample 3 (450g), and Sample 5 (600g). Each sample was placed in a 10cm x 10cm transparent acrylic litter container, with a 5cm layer. 10ml of water was added to each of the five containers. After standing for a period of time, litter clumps were scooped out to observe their adhesion to the bottom. The dryness and wetness of the bottom were recorded at 1 minute, 2 minutes, 3 minutes, 5 minutes, and 10 minutes. The test results are shown in Table 5.

[0053] Table 5

[0054] Quick-drying agents significantly affect the dryness of the litter box bottom, directly impacting the user experience. A damp environment not only easily breeds bacteria but also causes litter to stick to the bottom of the litter box. Adding a quick-drying agent can noticeably improve the dryness of the litter box bottom, keeping it dry.

[0055] The effect of added ingredients on cat litter pellet extrusion was tested using the following methods: Sample No. 1 was prepared using the proportions from Example 3; based on Example 3, Sample No. 2 was prepared using only bentonite and water.

[0056] Test method: Samples No. 1 and No. 2 were placed into a rotary granulator. The rotation speed of the granulator was controlled at 80 r / min and the feeding speed was 100 kg / h. A die with a diameter of 1 mm was used for granulation. The morphology of the produced particles and the continuous production time were recorded during the granulation process. The test results are shown in Table 6.

[0057] Table 6

[0058] Granulation with additives: Extruded granules are full and have a smooth surface texture, enabling continuous production. Granulation without the above additives: Extruded granules are not full and have a rough surface texture. After one hour of continuous production, they dry out, clogging the mold holes and even causing the mold to break, making continuous production impossible.
