为解决芳纶浆粕短纤维在橡胶中的分散难题,杜邦公司用一种新技术将浆粕形式的短纤维和某种弹性体混合预制成所谓的“工程弹性体”。这种工程弹性体的专利技术,使芳纶浆粕纤维能够在弹性体中充分伸开并被完全湿润,因而使工程弹性体在与橡胶共混时,实现了芳纶浆粕短纤维在橡胶中的充分分散,达到了最佳的补强效果。用工程弹性体(内含芳纶浆粕纤维)补强的胶料,具有高模量、耐撕裂、抗磨耗,不提高生热和硬度的优异性能,使其在橡胶工业中得到越来越重要的应用。
In order to solve the problem of dispersion of aramid pulp staple fibers in rubber, DuPont uses a new technology to preform so-called “engineering elastomers” by mixing pulp-like staple fibers and an elastomer. This engineering elastomer patented technology, so that aramid pulp fibers can be fully extended in the elastomer and is fully wetted, so that the engineering elastomer in the rubber blend, the realization of aramid pulp short fibers in the rubber In the full dispersion, to achieve the best reinforcement effect. Rubber compounds reinforced with engineered elastomers (containing aramid pulp fibers) with high modulus, tear resistance, abrasion resistance, excellent properties that do not increase heat build-up and hardness, and have gained traction in the rubber industry The more important application.
