Problems solved by technology

[0011] To sum up, the existing rodent litter has the following deficiencies: one is that naturally growing wood or herbaceous plants are widely used as raw materials, which may be polluted by microorganisms, heavy metals, and pesticide residues, and are not easy to eliminate in the production process; the other is water absorption. The property is still not strong enough, there is no water retention function, causing the gas in the urine and feces to volatilize, and it is easy to produce odor; the third is that there is no antibacterial effect, and it is easy to become the carrier of bacterial growth after absorbing urine; the fourth is that there is no standardized production and no odor. Bacteria packaging, which cannot be stored for a long time; Fifth, the process of replacing the litter is time-consuming and manpower-consuming, and the poor handling of the litter after use will cause secondary pollution

preparation example Construction

[0040] ① Preparation of nano-zinc oxide finishing agent: heat zinc acetate dihydrate in a water bath at 80°C, stir and dissolve in absolute ethanol 5 times its volume or mass, and cool to obtain solution A; Dissolve 20% lithium hydroxide monohydrate in 10 times the volume or mass of absolute ethanol, and ultrasonically treat for 10 minutes to obtain solution B; in the state of vigorous stirring, slowly drop solution B into solution A to obtain nano-zinc oxide finishing stock solution;

[0041] ② Preparation of copper sulfate finishing agent: Dissolve copper sulfate with a mass of 1 / 2 of zinc acetate dihydrate in an ethanol solution of 20 times the volume or mass at room temperature. The mass concentration of the ethanol solution is 10% to make copper sulfate Finishing agent stock solution;

[0042] ③ Finishing of non-woven fabrics: Take 2 volumes of nano-zinc oxide finishing agent stock solution, 1 volume of copper sulfate finishing agent stock solution, add 2000 volumes of d...

Embodiment

[0049] The three-layer structure of the new rodent bedding is produced and processed separately and finally bonded by heat. This embodiment is specifically carried out according to the following steps:

[0050] (1) diversion layer

[0051] Adopt the double-effect (surface hydrophilic, bottom surface water-repellent) perforated non-woven three-dimensional diversion layer material (polypropylene resin) existing on the market, with a weight of 30-50g / m 2 . The material has holes in a funnel-shaped structure, and the surface tension of the liquid makes it oriented to infiltrate into it. When the liquid pours in, the holes make the lower penetration resistance almost zero, and the infiltration amount increases; the infiltrated liquid is not easy to produce concentric circle diffusion. Instead, it falls into the water at a single point, directing the liquid vertically into the core.

[0052] (2) Absorbent core layer

[0053] The main raw materials for manufacturing the absorbent...

Abstract

The invention discloses a rodent pad layer and a preparation method of the rodent pad layer. The pad layer is respectively formed by three layers of materials including a flow guide layer, an absorption core layer and a bottom film from top to bottom through hot gluing, wherein the flow guide layer is polypropylene resin, the absorption core layer is formed by non-woven fabric and fluff pulp mixed absorption powder through laminating pressing, and the bottom film is a degradable polyethylene film. The rodent pad layer is formed by adopting the flow guide layer, the absorption core layer and the bottom film through hot gluing, has the water absorption, ammonia absorption and bacteriostatic effects, and can become a pad layer replacing the existing experiment animal pad materials through simple work procedures of shearing, press forming, sterilization and encapsulation, and in addition, the rodent pad layer has the advantages that the preparation process is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the field of consumables for experimental animal breeding, and relates to an animal bedding, in particular to a novel rodent bedding and a preparation method thereof. Background technique [0002] Litter is in direct contact with experimental animals, can absorb moisture and animal excrement, and maintain the cleanliness of the cage and the animal itself, which is a key environmental factor that affects experimental animal data and animal health. At present, several small rodent bedding materials at home and abroad are introduced as follows: [0003] (1) Wood shavings and wood chips [0004] Wood shavings and wood chips are the most widely used animal bedding, with a wide range of sources and low cost. At present in our country, this kind of bedding is generally provided by the experimental animal center of each unit, or used by the user after disinfection and sterilization by himself. The cost is low but the quality is uneve...
