A conductive liquid silicone rubber is described, in which the conductive filler used in the conductive liquid silicone rubber includes single-walled carbon nanotubes. Also described, is the use of single-walled carbon nanotubes as a conductive filler to prepare a single-walled carbon nanotube conductive liquid silicone rubber composite material. A two-step pre-mixing method and formulation design is also described that can effectively disperse the single-walled carbon nanotubes at an extremely small addition amount minimizing problems such as agglomeration, sedimentation and precipitation while reducing viscosity and enhancing processing performance. A resulting conductive liquid silicone rubber can exhibit not only a low conductive filler addition amount and excellent electrical properties, but also excellent physical and mechanical properties and weather resistance, as well reduced pollutant generation during vulcanization.

This invention relates to a highly flame-retardant adhesive for high-polymer materials. The adhesive contains a phenolic hydroxyl flame retardant which is prepared from organic amino compounds by one-step reaction with simple and controllable synthesis conditions and high synthesis efficiency; and then the highly flame-retardant adhesive can be obtained by blending the flame-retardant and the adhesive. The highly flame-retardant adhesive synthesized in the invention can be directly used as an adhesive for polymer materials to produce high adhesion strength, or used as a basic formula and prepared into composite adhesives through the addition of other fillers, or used as a primer agent to modify surfaces of polymer materials, so as to meet different needs on various special occasions.
