Abstract

The invention relates to a heat-resistant clothing hot melt adhesive, which is characterized by comprising the following components by mass percent: 29-46.45% of hot melt adhesive, 26.1-45.52% of PE, 0.29-2.32% of bulking agent, 0.29-2.32% of sensitizer or sensitizing agent, 0.95-9.9% of nanoscale montmorillonoid or nanoscale clay, 0.05-0.5% of compatilizer, 5-20% of tackifier, 1-10% of plasticizer and 0.1-2% of antioxygen, wherein the hot melt adhesive is one or more combination of PET, PA, TPU and EVA. The preparation method comprises the following steps: 1) adding the PE, bulking agent, sensitizer or sensitizing agent into a blender and mixing for standby use; 2) adding the compatilizer and nanoscale montmorillonoid or nanoscale clay into the blender, and mixing for standby use; 3) adding the hot melt adhesive into the blender, and mixing with the blending materials obtained in the step 1 and 2; 4) slowly pouring the tackifier, plasticizer and antioxygen and mixing the materials; and 5) pelleting the obtained blending in the step 4, cooling and dicing to obtain the heat-resistant clothing hot melt adhesive. The preparation method of the invention is simple in process, and the obtained hot melt adhesive has good flexibility, adhesiveness and thermal stability.

Description

technical field [0001] The invention relates to a high-temperature-resistant clothing hot-melt adhesive and a preparation method thereof, in particular to a high-temperature hot-melt adhesive for high-grade clothing and a preparation method thereof. Background technique [0002] PET, PA, TPU or EVA-based hot melt adhesives have the advantages of high bonding strength and good medium resistance, and have good bonding properties to wood, metal, ceramics, fabrics, paper and other polyolefin materials, but their heat The stability makes its application subject to certain restrictions. At high temperatures, hot melt adhesives based on PET, PA, TPU or EVA tend to soften or even melt, losing their bonding effect. Therefore, these untreated hot melt adhesives are not conducive to use at high temperatures. CN 101070455A discloses a method for curing cross-linked EVA by adding dicumyl oxide, which improves the heat-resistant grade of EVA; CN 1800287A discloses a modified EVA hot-mel...
