Special visible ear tag material for livestock, as well as preparation method and ear tag thereof

Abstract

The invention provides a special visible ear tag material for livestock, as well as a preparation method and an ear tag thereof. The material is prepared from the following materials in parts by weight: 90-95 parts of modified thermoplastic polyurethane elastomer, 6-8 parts of laser coding agent and 4-6 parts of master-batches, wherein the modified thermoplastic polyurethane elastomer is prepared from TPU, an anti-UV agent and an antibacterial agent. The invention further relates to a method for preparing the ear tag material and an ear tag prepared from the material. The advantages of the thermoplastic polyurethane, including oil resistance, toughness, wear resistance, aging resistance and the like, are utilized, the weather resistance of the material is improved by adding the anti-UV agent, and the technical problem that an livestock ear tag is aged after being worn for a long time, is fragile-fractured and falls can be solved; the technical problem of livestock ear is inflammatory and diseased, since the wearing the ear tag for a long time can be solved by adding the antibacterial agent; and the technical problem that laser labeling cannot be directly carried out on the surface of the thermoplastic polyurethane elastomer can be solved.

Description

technical field [0001] The invention relates to a special visual ear tag material for livestock, a preparation method thereof and an ear tag, and belongs to the technical field of animal ear tag materials. Background technique [0002] Ear tags are plastic tags worn on the ears of livestock to trace their origin. In the prior art, polyethylene plastic is usually used to make ear tags. Cows, sheep and other commercial livestock for meat are generally kept for half a year to one year, and there is no problem in using ear tags made of modified polyethylene plastics. The stocking time can reach more than three years. After wearing ordinary polyethylene ear tags on the ears for one year, due to the aging of polyethylene plastic under the action of air, sunlight and oxygen, the ear tags are prone to embrittlement, fracture, and fall off, which affects the quality of the breeding stock. Feeding management. [0003] After searching, some researchers in the prior art have proposed...

Problems solved by technology

[0009] The material of the present invention adopts thermoplastic polyurethane elastomer, while improving toughness, wear resistance and other properties, by adding anti-UV agent and antibacterial agent, the weather resistance of the material is improved, and the antibacterial performance is improved, so as to solve the problem of livestock ear tags being worn in the air for a long time. , rain, sunlight and oxygen will cause aging, ear tags will become brittle, break, fall off, animal ears will become inflamed and cause animals to get sick; at the same time, by adding laser marking agent, it can solve the problem that ordinary thermoplastic polyurethane elastomers cannot be directly printed on its surface. Technical problems of laser marking
