摘要： The present invention relates to the technical field of polymer composite materials, and specifically, to a shear thickening composite material, a preparation method therefor, and use thereof. According to the present invention, a solid composite material with shear thickening performance is prepared by limiting the types and contents of all components in raw materials. This composite material is kept soft and has a proper elastic shape under a normal state, and can be rapidly subjected to strain enhancement through local density increase when being rapidly and violently impacted or extruded, so that a significant shear thickening phenomenon is presented, namely this material is a hard solid when being impacted by an external force, then this material has an increasing strength with the increase of the external force, and this material restores to an original relaxed, soft, and elastic state when the external force is removed.

摘要： A polyurethane composition, which contains at least one isocyanate-group-containing polymer, obtained from the reaction of at least one polyol with at least one diisocyanate, and at least one oxazolidine of the formula (I). The polyurethane composition allows one-component moisture-curing adhesives, sealants or coatings that have good storage stability, long open times and cure quickly to give a surprisingly non-tacky material having pronounced high-resilient properties.

摘要： A polyurethane foam, a polyurethane/polyorganosiloxane foam, and a polyurethane foam polyurethane/polyorganosiloxane foam material are disclosed and described herein. The materials are formed in the presence of a polymerization reaction initiator (an isoprenoid compound), and a polymerization reaction accelerator. The polyurethane foam is formed from an isocyanate and a polyol. The polyurethane foam polyurethane/polyorganosiloxane foam material comprises the polyurethane foam which is cross-linked to the polyurethane backbone to a polyurethane/polyorganosiloxane foam. Optional gelling agents, emulsification control agents, reinforcement fillers, cross-linkers, reinforcement polymers, rubber reinforcers, silk proteins, emollients, stabilizers and colorants are also described. The polyurethane and polyurethane-polyorganosiloxane foam materials exhibit a high degree of flexibility, resilience and excellent impact absorption.
