Description

technical field [0001] The invention relates to a preparation method of water-based glue for ultra-high modulus polyethylene fibers, and belongs to the field of adhesive synthesis. [0002] technical background [0003] Ultra-high molecular weight polyethylene (UHMWPE) is a polyethylene (PE) with a relative molecular weight greater than 1.5 million. Its molecular structure is exactly the same as that of ordinary polyethylene. chain group. Although the structure of UHMWPE is similar to ordinary PE, the molecular weight of UHMWPE is much higher than that of ordinary PE, so it has excellent functions that ordinary PE and other applied materials do not have, such as wear resistance, excellent mechanical properties, corrosion resistance, and no water absorption. , Excellent impact resistance. However, due to the easy crystal orientation, symmetrical structure and inactive groups of the UHMWPE molecular structure, the UHMWPE surface is extremely inert, the surface energy is extre...
