Abstract
The present invention relates to the technical field of rubber materials, and discloses a functional modification of reclaimed rubber material and use thereof in making safety gloves, wherein by using the hyperbranched nitrile butadiene rubber-polyurethane as the filling and modification agent, mixing with the nitrile butadiene rubber and reclaimed nitrile butadiene rubber for modification, the hyperbranched polyurethane has three dimensional branched network structures, in the meanwhile, nitrile butadiene rubber molecular chains are contained in the main chains, so that the hyperbranched nitrile butadiene rubber-polyurethane, the nitrile butadiene rubber and the reclaimed nitrile butadiene rubber have good interface compatibility, and the hyperbranched nitrile butadiene rubber-polyurethane, the nitrile butadiene rubber and the reclaimed nitrile butadiene rubber form three-dimensional interlinking networks, so that the mechanical properties such as tensile strength and tear strength of the reclaimed rubber composite materials are improved.
