Embodiment 1
[0023] The preparation method of healthy low-temperature hot-melt adhesive, raw materials include the following components by weight percentage: 45 parts of TPU hot-melt adhesive resin, 10 parts of PETG, 25 parts of negative ion / bamboo activated carbon composite material, 3 parts of compatibilizer
[0024] (1) Put the above-mentioned raw materials into the storage mechanism and remove metal through high-intensity magnetism;
[0025] (2) Transport each raw material into the material tank and stir for 30 minutes until uniform;
[0026] (3) The stirred raw materials are transported to the feed hopper of the tape casting extruder after secondary strong magnetic demetallization, and are fed to the screw machine at a constant speed by the metering and feeding mechanism according to the preset quantity, and then passed through the screw machine 130 ℃ high-temperature melting and kneading to uniformly cast into sheets, and then cold-pressed to shape;
[0027] The TPU hot melt adhesiv...
