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
The consumption articles for use field that the invention belongs to experimental animal feeding, relates to a kind of animal bed course, especially a kind of novel rodent bed course and preparation method thereof.
Background technology
Bedding and padding directly contact with laboratory animal, and the excreta of energy adsorption moisture and animal maintains in cage and the sanitation and hygiene of animal itself, is the critical environments factor that affects laboratory animal data and animal health.Several Small rodents bedding and padding both domestic and external are described below at present:
(1) wood shavings and wood chip
Wood shavings, wood chip are to apply the most general animal bedding and padding, wide material sources, and cost is lower.In China, this bedding and padding are generally provided by constituent parts Experimental Animal Center at present, or by using after the sterilizing of user's self-disinfecting, with low cost but quality is uneven.Developed country bedding and padding are produced professional factory, through selecting materials, fragmentation, dedusting, be dried, the operation such as compression, packaging, sterilizing, quality requirement is very strict, cost can corresponding rising.The limitation of wooden bedding and padding is: the one, and material source is difficult to review, difficult quality guarantee, a lot of seeds contain aromatic substance discomfort and are fit to do laboratory animal bedding and padding; The 2nd, the by product of wooden bedding and padding chain timbers material processing, the possibility of pollutions such as dust, bacterium, heavy metal are very high, and general sterilization cannot be removed completely; The 3rd, waste timber, does not meet environmental requirement.
(2) corn stalk, straw and wheat straw
Corn stalk, straw pass through to be dried, pulverize, sterilize, are dried the operations such as rear, can make animal bedding and padding.These class bedding and padding, source is sufficient, soft comfortable, is well suited for breeding mouse and uses, and its water imbibition, suction-operated are better than wooden bedding and padding.But stalk bedding and padding contain and are much difficult to the microorganism killed, and condition of storage is had relatively high expectations, and are easy to make moist mouldy, and raw material seasonality is very strong in addition, is difficult to ensure steady production.
(3) corncob
Corncob good water absorption, pollutes less, easy to use, is convenient to store.The wood chip that its general state uses than tradition is greatly improved, and its cleannes and water imbibition are all better than wood chip bedding and padding, low to the cytotoxicity of laboratory animal, and can reduce the frequency of changing bedding and padding.But corncob remains the carrier of bacterial growth, after long-time use, easily grow microorganism, distribute unpleasant gas.
(4) fibrous paper
Fibrous paper good hygroscopicity, can better control the smell of ammonia, is the novel animal bedding and padding of one that produce in recent years.Paper material is good to urine diffusibility, but there is no the function of storing liquid, therefore in urine gas compared with volatile and produce stink; And most fibrous paper derive from the waste paper of recovery, the heavy metals such as Qi Zhongqian, mercury often exceed standard, and the health of laboratory animal is caused to adverse effect.
In sum, existing rodent bedding and padding have following deficiency: the one, and generally use the timber of self-sow or herbaceous plant as raw material, may have microorganism, heavy metal, pesticide residual contamination, and be difficult for eliminating at production link; The 2nd, water imbibition is still strong not, there is no water retaining function, causes gaseous volatilization in urine, ight soil, easily produces stink; The 3rd, all without antibacterial action, and absorbing the carrier that easily becomes bacteria breed after urine; The 4th, there is no standardization generation and aseptic packaging, cannot long term storage; The 5th, to change bedding and padding process and expend time in and manpower, the bedding and padding after use are processed bad meeting and are caused secondary pollution.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of rodent bed course and preparation method thereof is provided, this animal bed course adopts guide layer, absorbent core layer and counterdie to form by heat bonding, there is water suction, inhale ammonia, antibacterial effect, it can be through simple cutting, die mould, sterilization, packaging process, can become the bed course that substitutes existing laboratory animal bedding and padding, and, preparation technology is simple for this animal bed course, and cost is low.
The object of the invention is to solve by the following technical programs:
