Detailed Description
Example 1
The biodegradable pet nursing pad as shown in fig. 1 comprises a surface liquid permeable layer, an activated carbon layer, liquid absorbing paper, a liquid absorbing layer and an anti-leakage bottom layer, wherein the surface liquid permeable layer, the activated carbon layer, the liquid absorbing paper, the liquid absorbing layer and the anti-leakage bottom layer are arranged in the biodegradable nursing pad from top to bottom, and all the parts of the biodegradable nursing pad are made of biodegradable materials. The biodegradable nursing pad is mainly prepared by the following steps:
grinding activated carbon, sieving with 20 mesh standard sieve to obtain powder granule with uniform particle size, and soaking in CaCl2Adsorbing in water solution, and adsorbing CaCl2Drying the activated carbon in the solution to obtain the activated carbon layer raw material of the nursing pad, wherein CaCl is contained in the activated carbon layer2The mass ratio of the active carbon to the active carbon is 1: 15.
And uniformly mixing sodium alginate powder and the fluff pulp according to the mass ratio of 1:10 to obtain the liquid absorbing layer material.
The mass ratio of the activated carbon layer to the liquid absorption layer is 1:10, and the liquid absorption layer material is uniformly spread on the anti-leakage bottom layer, wherein the spreading amount is 0.15g/cm 2.
The active carbon layer, the liquid absorbing layer and the surface liquid permeable layer, the liquid absorbing paper and the anti-leakage bottom layer which are prepared according to the proportion are uniformly tiled and pressed together according to the sequence of the surface liquid permeable layer, the active carbon layer, the liquid absorbing paper, the liquid absorbing layer and the anti-leakage bottom layer from top to bottom, so that the degradable nursing pad with the smooth and attractive appearance is prepared.
The pet care pad prepared according to the above preparation process was tested for its ability to absorb physiological saline by the following experiments, including the specific steps of:
cutting a small sample of the nursing pad with the size of 1cm (length) multiplied by 1cm (width), and accurately weighing the sample;
uniformly pricking a plurality of small holes at different positions on the anti-leakage bottom layer by using needles, and then horizontally placing the nursing pad sample;
dropwise adding 0.9% of normal saline into the surface liquid permeable layer until the liquid seeps out from the anti-seepage bottom layer, and stopping dropwise adding;
accurately weighing the nursing pad sample absorbing the physiological saline, and obtaining the liquid absorption amount of the nursing pad sample according to the mass difference before and after the liquid absorption of the nursing pad sample.
The results show that the physiological saline absorbing capacity of the pet nursing pad is 2.90g/cm2。
The pet care pad prepared according to the preparation process is tested for the capability of removing peculiar smell and absorbing peculiar smell through the following experiments, and the specific steps are as follows:
cutting a small sample of the pad prepared by the preparation process with the size of 60cm (length) multiplied by 60cm (width) and a common nursing pad with the same size;
collecting 400mL of fresh pet urine, dividing the fresh pet urine into two equal parts, respectively absorbing 200mL of urine by the two cut nursing pads with the same size and shape, and then placing the nursing pads into a closed container; after 24h, the respective ammonia concentration was determined.
The results showed that the ammonia concentration in the container containing the nursing pad of the present invention was 14.2% of the ammonia concentration in the container containing the conventional nursing pad.
Example 2
4 sets of parallel experiments are designed, the preparation steps of the nursing pad are the same as those in the example 1, except that the mass ratio of the sodium alginate powder to the fluff pulp in the liquid absorbing layer is changed, other conditions are the same as those in the example 1, and the influence of the mass ratio of the sodium alginate to the fluff pulp in different proportions on the liquid absorbing capacity of the nursing pad is examined. Wherein sodium alginate is not added in the 1 group of sample liquid absorbing layers, only the villus pulp (sample 2-1) is used, and the mass ratio of the sodium alginate powder to the villus pulp in the other 3 groups of sample liquid absorbing layers is respectively 1:5 (sample 2-2), 1:10 (sample 2-3) and 1:15 (sample 2-4).
The results of the experiments are shown in the following table:
Figure RE-GDA0002334950340000031
the above experimental results show that the more sodium alginate is used in the liquid absorption layer, the stronger the liquid absorption capacity of the nursing pad, because the water absorption capacity of the sodium alginate gel is larger than that of the fluff pulp.
The sample 2-1 had poor water retention after imbibing, and had liquid exudation under light pressure with hands, the samples 2-2, 2-3 and 2-4 had better water retention and had no water exudation under light pressure, because the samples 2-2, 2-3 and 2-4 had sodium alginate in their imbibing layers, which was associated with Ca leached from the activated carbon layer2+After reaction, a hydrogel is formed and the water is locked in the gel.
Example 3
Design 5 parallel experiments, the pad preparation procedure was the same as in example 1, except that the suction was changedThe spreading amount of the liquid layer material spread on the anti-leakage bottom layer was the same as in example 1, and the influence of the spreading amount of the different liquid-absorbent layer materials on the anti-leakage bottom layer on the liquid-absorbing capacity of the nursing pad was examined. Spreading amounts of the liquid absorbing layer materials of 5 groups of experimental samples on the anti-leakage bottom layer are respectively 0.08g/cm2(sample 3-1) 0.12g/cm2(sample 3-2) 0.15g/cm2(sample 3-3), 0.18g/cm2(samples 3-4) and 0.20g/cm2(sample 3-5). The results of the experiments are shown in the following table:
Figure RE-GDA0002334950340000041
the experimental results show that the liquid absorption capacity of the nursing pad can be controlled by the spreading amount of the liquid absorption layer material, so that different use requirements are met. The liquid absorbing capacity of the nursing pad is improved along with the increase of the spreading amount of the liquid absorbing layer.
Example 4
Design 3 sets of parallel experiments, the nursing pad preparation procedure was the same as in example 1, except that CaCl in the activated carbon layer was changed2The mass ratio to the activated carbon and other conditions were the same as in example 1, and different CaCl in the activated carbon layer was examined2The effect of the liquid absorption capacity of the care pad compared to the quality of the activated carbon. CaCl of 3 groups of test samples2The mass ratio of the active carbon to the active carbon was 1:10 (sample 4-1), 1:15 (sample 4-2) and 1: 20 (sample 4-5), respectively. The results of the experiments are shown in the following table:
Figure RE-GDA0002334950340000042
the above experimental results show that CaCl in the activated carbon layer2The amount of (C) also has an influence on the liquid-absorbing capacity of the care pad, CaCl2The more the amount of the active carbon, the liquid absorption capacity of the nursing pad is reduced, which is caused by CaCl in the active carbon layer2The more Ca leached out to the liquid-absorbent layer2+The increase of the cross-linking degree of the sodium alginate gel, the reduction of the intermolecular network space and the reduction of the liquid absorption capacity.
Sample 4-3 had poor water retention after imbibing, and had exudation of liquid with light hand pressure, samples 4-1 and 4-2 had good water retention and no exudation of water under light pressure. This is due to CaCl in the activated carbon layer of sample 4-32Less Ca leached out to the liquid-absorbing layer2+Less sodium alginate gel formed after imbibing is low in crosslinking degree and gel strength, so that the water retention performance is poor.
It can be seen that CaCl is in the activated carbon layer of the nursing pad2When the mass ratio of the nursing pad to the active carbon is 1:15 respectively, the comprehensive using effect of the nursing pad is optimal.
Example 5
Designing 3 groups of parallel experiments, wherein the preparation steps of the nursing pad are the same as those in example 1, except that the mass ratio of the activated carbon layer to the liquid absorbing layer is changed, other conditions are the same as those in example 1, and the influence of the mass ratio of the activated carbon layer to the liquid absorbing layer on the odor removing capability of the nursing pad is examined. The mass ratios of the activated carbon layer to the liquid absorbent layer of the 3 experimental samples were 1:5 (sample 5-1), 1:10 (sample 5-2) and 1:15 (sample 5-3), respectively. The results of the experiments are shown in the following table:
Figure RE-GDA0002334950340000051
the above experimental results show that, compared with the pet care pad without activated carbon, the ammonia gas concentrations in the containers containing the sample 5-1, the sample 5-2 and the sample 5-3 are respectively only 10.1%, 14.2% and 19.4% of the ammonia gas concentration in the container containing the ordinary care pad. Therefore, the activated carbon has good peculiar smell removing capability, and the more the dosage is, the stronger the peculiar smell removing capability is.
In conclusion, the biodegradable pet care pad disclosed by the invention has a good moisture absorption effect, and can remove peculiar smell generated by pet excrement and purify air; on the other hand, due to the adoption of biodegradable materials, the nursing pad can be used as a fertilizer after being used and decomposed by compost, so that the cyclic utilization of resources is realized, and the nursing pad is environment-friendly.
