Embodiment 1
[0023] A kind of TPU masterbatch, it comprises following raw material component by weight:
[0024]
[0025] Wherein, the organic fluorescent material is a triphenylamine derivative; the colorful powder is a 40 μm color-changing glass microsphere grafted with an amino group.
[0026] Preparation:
[0027] 1) Dry the above raw material components at a temperature of 70-80°C for 1-2 hours;
[0028] 2) Put the dried TPU masterbatch, eighteen-functionality aliphatic polyurethane and hydrogen-containing silicone oil into the twin-screw extruder and mix evenly. The mixing time is 0.5-1h, and then add nano-silver particles, organic fluorescent materials, The colorful powder, polyethylene wax, lubricant and defoamer are continuously stirred and mixed, the stirring temperature is 120-160°C, and the stirring time is 1-1.5h, and then granulated by a granulator to obtain the finished product of TPU masterbatch in Example 1.
Embodiment 2
[0030] A kind of TPU masterbatch, it comprises following raw material component by weight:
[0031]
[0032]
[0033] Wherein, the organic fluorescent material is selected from the compound of triphenylamine derivatives and porphyrin compounds; the colorful powder is 80 μm color-changing glass microspheres grafted with carboxyl groups.
[0034] The preparation method of this embodiment is the same as the preparation method of embodiment 1, and the finished TPU masterbatch of embodiment 2 is prepared.
Embodiment 3
[0036] A kind of TPU masterbatch, it comprises following raw material component by weight:
[0037]
[0038] The organic fluorescent material is a thiazole derivative; the colorful powder is a 60 μm color-changing glass microsphere grafted with an amino group and a carboxyl group.
[0039] The preparation method of this example is the same as that of Example 1, and the finished TPU masterbatch of Example 3 is prepared.

Abstract
The invention discloses a TPU master batch. The TPU master batch is prepared from the following raw material components in parts by weight: 50-80 parts of TPU master batch, 20-30 parts of aliphatic polyurethane with 18 functionality, 0.5-1 part of nano silver particles, 0.1-1 part of organic fluorescent material, 0.3-3 parts of colorful powder, 1-8 parts of polyethylene wax, 1-5 parts of hydrogen-containing silicone oil, 0.5-2 parts of lubricating agent and 0.5-2 parts of defoaming agent. The TPU master batch and aliphatic polyurethane with 18 functionality are compounded to serve as substrateresin, so that the TPU master batch has the excellent anti-yellowing function, meanwhile, nano silver, the organic fluorescent material and the colorful powder are added, polyethylene wax is utilizedto make the functional material be uniformly dispersed in the substrate resin, and the prepared TPU master batch does not only maintain the excellent mechanical performance of the common TPU material, but also has the various kinds of functions such as wear resistant, yellowing resistant, fluorescent and antibacterial. The invention further discloses the preparation method of the TPU master batch, the technology is simple, the production cost is low, the stability of the finished product is good, and large-scale industrialized production is facilitated.
Description
technical field [0001] The invention relates to the field of polymer materials, in particular to a TPU masterbatch. Background technique [0002] TPU (Thermoplastic polyyrethane, thermoplastic polyurethane) is a new type of organic polymer synthetic material, and it is also an ideal material to replace PVC and PU. [0003] Thermoplastic polyurethane is widely used, for example, it can be used for fabrics and inner lining materials of footwear such as sports shoe logo, sports shoe air cushion, mountaineering shoes, snowshoes, golf shoes, roller skates, ready-made clothing such as snow suits, raincoats, Windbreakers, cold jackets, field uniforms, diapers, physiological pants, and other fabric composite materials (waterproof and moisture-permeable), medical products such as surgical gowns, hats, shoes, hospital mattresses, ice packs, bandages, plasma bags, surgical dressing strips , masks, and other fabrics and inner materials, operating bed airbags, national defense products ...
