Problems solved by technology

Cows, sheep and other commercial livestock for meat are generally kept for half a year to one year. 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 their 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.

Embodiment 2

[0025] Embodiment 2 of the present invention. The modified material of laser two-dimensional code ear tag for breeding stock, a better solution is that its weight ratio is:

[0026] 97.6-98.3 parts of polyurethane, 1.9-2.1 parts of antimony trioxide,

[0027] 0.02 parts of dispersant, 0.07-0.08 parts of coupling agent.

[0028] The dispersant used is basf wax, the specific model is luwax EVA3 or Luwax op, and the coupling agent is titanate.

[0029] The production process is as in Example 1.

Embodiment 3

[0030] Embodiment 3 of the present invention. The modified material of laser two-dimensional code ear tag for breeding stock, the optimal ratio is:

[0031] 97.9 parts of polyurethane, 2 parts of antimony trioxide,

[0032] Basf wax (luwax EVA3) 0.02 parts, titanate (LG-144) 0.08 parts.

[0033] The preparation method is as follows, a. According to the above weight ratio, weigh 20% of the total weight of polyurethane, add antimony trioxide, basf wax (luwax EVA3) and titanate (LG-144), in a high-speed mixer or continuous modification Heat and stir in the unit equipment, the heating temperature is 175°, and the time is 1 hour. After fully mixing, add it to the twin-screw extruder, granulate and shape it through the water ring granulation equipment, and obtain A product after dehumidification by the dryer.

[0034] b. Weigh the remaining polyurethane in the formula, add the produced product A, stir in a high-speed mixer, mix thoroughly, add to the twin-screw extruder, granulate...

Abstract

The invention discloses a laser two-dimensional code ear tag modification material special for breeding stock. The modification material is characterized by comprising the following materials in part by weight: 97 to 99 parts of polyurethane, 1.5 to 2.5 parts of antimony trioxide, 0.01 to 0.03 part of dispersant and 0.05 to 0.09 part of coupling agent. By using the advantages of the thermoplasticpolyurethane such as oil resistance, toughness, abrasion resistance, ageing resistance and the like and adding a photo-oxidation stabilizing auxiliary agent, the weather resistance of the material isimproved, and the problems of ageing, brittleness, breakage, drop and the like under the actions of air, sunlight and oxygen after an ear tag is worn for long time are solved; and by adding a modifying material into the polyurethane, the laser processing performance of a thermoplastic polyurethane elastomer is enhanced, and batch production of laser processing on the thermoplastic polyurethane elastomer material is realized. Tested by the applicant, the drop, breakage or fracture rate of the ear tag made of the modification material does not exceed 2 percent when the ear tag is worn by the breeding stock in three years.

Description

technical field [0001] The invention relates to a modified material of a laser two-dimensional code ear tag for breeding livestock and a preparation method thereof, belonging to the technical field of livestock 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. Contents of the invention [0003] The object o...
