Abstract

A novel anti-impact protective micro-gel was synthesized via precipitation polymerization, in which diphenylmethane diisocyanate (MDI) was employed as chain extender. And the structure and morphology of microgel were characterized via IR and TEM. Therefore, the microgels were dip-coated into 3D fabrics to prepare anti-impact protective fabrics. The optimum feed ratio of microgels (m(Si)/m(B)=15:1, m(MDI)=2.00%, m(TIPT)=4.20%) was determinated through an orthogonal design based on the mechanical performance of anti-impact protective fabrics. The investigation suggested that the anti-impact performance of anti-impact protective fabrics, which were finished with microgels containing MDI, could be significantly improved in that the molecular weight of polymer was increased stemming from the introduction of MDI. Meanwhile, not only the low reaction and drying temperature could be realized, but also the viscosity of reaction mixture and final product could be sharply dropped after MDI was employed.
