Description

Technical Field

[0001] This invention relates to the field of biological bedding technology, specifically to a resource-processable animal bedding material and its preparation method. Background Technology

[0002] Animal husbandry requires a large amount of bedding material to absorb excrement and moisture, adsorb ammonia, deodorize and inhibit bacteria, keep warm, regulate body temperature, provide cushioning and protection, reduce injury, meet natural behavioral needs (such as nest building and nest storage), facilitate cleaning and management, reduce stress, stabilize physiological state, and protect cages and the environment.

[0003] Currently, commonly used animal bedding materials fall into three main categories: wood bedding, paper bedding, and plant fiber bedding. Wood bedding suffers from resource scarcity; paper bedding is expensive and has poor ammonia absorption; and among plant fiber bedding materials, corn cob bedding has weak water absorption. Therefore, this invention proposes a resource-recyclable animal bedding material and its preparation method. By processing corn stalks, it meets the natural behavioral needs of animals, which is beneficial to environmental protection and the recycling of waste corn stalks. Summary of the Invention

[0004] The purpose of this invention is to provide a resource-efficient animal bedding material and its preparation method, so as to solve the related technical problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following specific technical solutions: A method for preparing animal bedding that can be recycled includes the following process: raw materials are processed sequentially through a shredder, sieved, steamed at high temperature, activated, adsorbent is added, dried, vacuum packaged, and sterilized to obtain animal bedding.

[0006] Ideally, the raw material is corn stalks.

[0007] Ideally, the sterilization process is either high-temperature, high-pressure steam sterilization or irradiation sterilization.

[0008] Compared with existing bedding materials, the animal bedding material of the present invention has the advantages of high water absorption, good odor adsorption, low dust content, and resistance to mold growth. It is more in line with the biological characteristics of animals building nests and is closer to their natural habits, thus better meeting the needs of animals' natural behavior.

[0009] A more optimized method is to use an 8-12 mesh screen for dust removal.

[0010] In a more optimized manner, the specific process of high-temperature steaming is as follows: the corn stalks that have been shredded and sieved are placed in a fully automatic steam pressure cooking machine, saturated steam is added, and when the saturated steam temperature reaches 160~200℃, the temperature is maintained for 1~2 hours, and then dried.

[0011] In a more optimized manner, the specific process of the activation treatment is as follows: ferrous chloride, 1-2M hydrogen peroxide solution, and citric acid are added, and the mixture is stirred and activated at room temperature for 2-4 hours. Then, it is washed with water until the pH reaches 4-5 and dried.

[0012] Ideally, the mass ratio of corn stalks to hydrogen peroxide solution should be 1:(20~25).

[0013] Ideally, the molar ratio of ferrous chloride to hydrogen peroxide is (7~8):0.1.

[0014] Ideally, the amount of citric acid added should be 10-15% of the total mass of the reaction system.

[0015] More preferably, the raw materials include the following components by weight: 1-4 parts strawberry leaf powder, 3-5 parts coconut shell powder, and 70-100 parts corn stalks.

[0016] In a more optimized manner, the raw materials are obtained by the following process: mixing strawberry leaf powder, coconut shell powder, and corn stalks evenly to obtain the raw materials.

[0017] Ideally, the drying process conditions are as follows: drying at 70~80℃ for 3~4 hours.

[0018] Ideally, the amount of adsorbent added is 3 to 5% of the total mass of the bedding material.

[0019] Ideally, the adsorbent is prepared by the following process: Step (1): Mix soybean oil and sodium lignosulfonate evenly, place at a temperature of 45~55℃, and purge with nitrogen for 1~2 hours to obtain the oil phase; Step (2): Mix L-glutamine, acrylic acid and ammonia solution, stir evenly, add itaconic acid, octenyl succinate starch ester and potassium persulfate, and continue stirring evenly to obtain the aqueous phase; Step (3): Add the aqueous phase to the oil phase at a constant temperature of 45~55℃ and under nitrogen protection. Stir the mixture at a speed of 1000~1200rpm for 2~4 hours. After the reaction is complete, filter and dry to obtain the adsorbent.

[0020] Ideally, the mass ratio of soybean oil to sodium lignosulfonate is (40~50):0.3.

[0021] More preferably, the aqueous phase comprises the following components by mass: 40-55 parts L-glutamine, 4-8 parts acrylic acid, 20-30 parts ammonia solution, 1-2 parts itaconic acid, 1-3 parts octenyl succinate starch ester, and 0.5-0.8 parts potassium persulfate.

[0022] Ideally, the concentration of the ammonia solution is 25-28 wt%.

[0023] In the above technical solution, the surface area of ​​corn stalks is increased by shredding and high-temperature steaming, improving their adsorption of moisture, mud, and other substances. Dust is removed by sieving, and the bedding material is used to prepare organic fertilizer after use. High-temperature steaming breaks down the crystal structure of cellulose, making it easier for microorganisms to degrade, thus improving biocompatibility and fertilizer utilization. High-temperature steaming increases the bulk density of the raw materials, reducing oxygen permeability and inhibiting aerobic activity. Activation treatment can decompose urea, prevent urea alkali, and reduce ammonia gas. Hydrogen peroxide solution and Fe... 2+ Citric acid forms a Fenton-like system, generating highly oxidizing hydroxyl radicals. The carboxyl group in citric acid has a coordinating effect, forming an Fe-citric acid complex, which accelerates the Fe... 3+ To Fe 2+ The reduction process accelerates the oxidation of corn stalks, enriches pores, increases adsorption, and improves heat retention. Combining strawberry leaf powder, coconut shell powder, and corn stalks can improve the flexibility, water absorption, and stability of bedding, while reducing ammonia emissions. Strawberry leaf powder has antibacterial and antioxidant properties; its combination can effectively reduce the incidence of animal dermatitis, protect animal health, and improve meat quality. Combining it with coconut shell powder can improve the heat retention of bedding. Adjusting the pH to 4-5 acidifies the bedding, which helps neutralize urine alkali and reduce ammonia emissions.

[0024] Soybean oil, as the biomass oil phase, ensures the stable progress of the polymerization reaction and provides hydrophobic microdomains. Acrylic acid reacts with ammonia to form acrylate amine. Itaconic acid, L-glutamine, and octenyl succinate starch ester undergo cross-linking under the action of potassium persulfate initiator. Through the preparation process of adding the aqueous phase to the oil phase and high-speed shear dispersion, an adsorbent with high water absorption is formed, which improves the flexibility, stability, and water absorption of the bedding, thereby ensuring animal comfort, reducing foot inflammation and skin diseases, inhibiting ammonia generation and respiratory irritation, and benefiting animal husbandry.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. Compared with existing bedding materials, the animal bedding material of the present invention has the advantages of high water absorption, good odor adsorption, low dust content, and resistance to mold growth. It is more in line with the biological characteristics of animals building nests and is closer to the natural habits of animals, thus better meeting the natural behavioral needs of animals.

[0026] 2. This invention increases the surface area of ​​corn stalks by shredding and high-temperature steaming, improving their adsorption of moisture and mud. Screening removes dust and disrupts the crystalline structure of cellulose, making it easier for microorganisms to degrade. High-temperature steaming increases the bulk density of the raw materials, reducing oxygen permeability and inhibiting aerobic activity. Activation treatment decomposes urea, prevents urinary alkali buildup, and reduces ammonia emissions. Accelerated oxidation of corn stalks enriches pores, increases adsorption, and improves insulation performance. The combination of strawberry leaf powder, coconut shell powder, and corn stalks improves the bedding's flexibility, water absorption, and stability, while reducing ammonia emissions. It effectively reduces the incidence of animal dermatitis, protects animal health, and improves meat quality. The addition of coconut shell powder enhances the bedding's insulation performance. Adjusting the pH to 4-5 acidifies the bedding, which helps neutralize urinary alkali and reduces ammonia emissions.

[0027] 3. This invention improves the flexibility, stability and absorbency of bedding by adding adsorbents, ensuring animal comfort, reducing foot inflammation and skin diseases, inhibiting ammonia generation and respiratory irritation, which is beneficial to animal husbandry.

[0041] Experimental test: The pads prepared in Examples 1-6 and Comparative Examples 1-5 were used as samples for performance testing. Water absorption rate test method: Weigh the total mass of the sample after water absorption and before water absorption according to [DB32 / T 2129-2012], and calculate the water absorption rate; Dust content test method: Place the sample into a 50-mesh standard sieve, vibrate and sieve, collect the fine dust passing through the sieve and weigh it, and calculate the dust content; Moisture content test method: The moisture content of the sample shall be determined by the drying loss method according to [DB32 / T 2129-2012]; Mold rate test method: According to [GB 4789.2-2022], take a feeding box with a length of 930mm × width of 616mm × height of 295mm, and lay down bedding with a thickness of 3cm.

[0042] The experimental data are as follows: Table 1

[0043] Results and Discussion: The data in the table above show that the bedding material of this application has high water absorption, good absorption of animal excrement odor, is suitable for the nesting habits of experimental animals, has low dust content, and is not prone to mold.

[0044] Compared with Example 1, Comparative Example 1 used corn cobs as the raw material for preparing animal bedding, and Comparative Example 2 used wood shavings as the raw material for preparing animal bedding. Corn cob bedding has a low water absorption rate, and although wood shavings bedding has better water absorption, it has a high dust content. The mildew rate and ammonia adsorption are not as good as those of the present invention. It can be seen that the present invention uses corn stalks as the raw material for preparing animal bedding, which has the advantages of high water absorption rate and low dust content, and has obvious technical advantages in low dust and ammonia adsorption.

[0045] Compared with Example 4, Comparative Example 3 used raw materials that had not undergone activation treatment to prepare bedding material, and the ammonia concentration increased. This shows that by activating corn stalks, the pore structure of corn stalks can be effectively oxidized and enriched, thereby enhancing the adsorption capacity for ammonia.

[0046] Compared with Example 4, no adsorbent was added to the raw materials used in Comparative Example 4, and the mold rate and ammonia concentration increased. It can be seen that by adding adsorbent, the water absorption, stability and antibacterial properties of the bedding material are improved, effectively reducing the risk of mold growth and improving the adsorption effect of the bedding material.

[0047] Compared with Example 4, Comparative Example 5 used raw materials that were neither activated nor had adsorbents added. The water absorption rate was reduced, the mold rate was increased, and the ammonia concentration was increased. It can be seen that the activation treatment and adsorbents have a synergistic effect on improving the overall performance of the bedding material.

[0048] For those skilled in the art, it is obvious that the present invention is not limited to the details disclosed in the exemplary embodiments described above. The present invention can be implemented in other specific ways without departing from its spirit and essential characteristics. Therefore, the foregoing embodiments should be considered exemplary rather than restrictive from any perspective. The scope of protection of the present invention is defined by the appended claims. Therefore, all variations falling within the meaning and scope of the equivalent elements of the claims should be attributed to the scope of the present invention.
