Cold-resistant cattle ear label and preparation method thereof

Abstract

The invention provides a cold-resistant cattle ear label and a preparation method thereof. The preparation method of the cold-resistant cattle ear label comprises the steps that (1) an ear label neckis manufactured; (2) an ear label surface is manufactured, specifically, 100 parts of PVC resin, 25-28 parts of dioctyl phthalate, 22-30 parts of dioctyl terephthalate, 3-7 parts of epoxidized soybeanoil, 25-28 parts of vinyl acetate, 18-22 parts of inorganic filler, 1-3 parts of antimonous oxide, 0.1-0.2 part of polyethylene wax, 0.1-0.2 part of stearic acid and 2-5 parts of a Ca-Zn composite stabilizer by weight are weighed and are added into an internal mixer to be internally mixed after being evenly mixed, a material obtained after internal mixing is injected into a mold to form protective layers on the two sides of the ear label surface through injection molding, then a chip is embedded between the protective layers formed on the two sides of the ear label surface through injection molding, and afterwards, hot-pressing formation is conducted from the periphery to perforate the edge of the ear label surface to form a connecting part; and (3) assembling is conducted. By adoption ofthe cold-resistant cattle ear label and the preparation method thereof, the situation that the ear label is damaged due to frost cracks of the ear label surface in an alpine region can be effectivelyavoided, and the service life of the ear label is prolonged.

Description

Technical field: [0001] The invention relates to a cold-resistant cattle ear tag and a preparation method thereof, belonging to the technical field of ear tag production. Background technique: [0002] With the improvement of people's living standards, beef food safety has increasingly become the focus of people's attention, and more and more countries use ear tags for beef food traceability management. Ear tags are one of the conventional technologies for beef cattle breeding. Numbers or barcodes are set on the ear tags for individual identification of beef cattle and establishment of beef cattle breeding files corresponding to the numbers or barcodes on the ear tags, so as to trace the epidemic diseases and product safety of beef cattle , the ear tag is one of the animal identifications, used to prove the identity of the livestock, the symbol that carries the individual information of the livestock, and is applied to the ears of the livestock. The ear tag is composed of t...

AI Technical Summary

Problems solved by technology

Because the climatic conditions are suitable for the growth and development of cattle, it is big and fat, and has high economic benefits. Ear tags are items worn by cattle for life. For cattle in cold regions, the cold resistance of ear tags is particularly important. The existing ear tags The surface of the label is generally made of resin products, which are easy to be brittle after being frozen in cold regions, which affects its service life
