Title:
ENVIRONMENTALLY-FRIENDLY FLEXIBLE CONDUCTIVE POLYURETHANE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/151174
Kind Code:
A1
Abstract:
Disclosed in the present invention are environmentally-friendly flexible conductive polyurethane and a preparation method therefor. The environmentally-friendly flexible conductive polyurethane is prepared from a component A and a component B by means of a two-component prepolymer in-situ solvent-free blending polymerization method according to a certain mass ratio. The component A is composed of polyol, a T-chain extender, diselenide diol, high conductivity carbon black, a dispersant, a catalyst, a leveling agent, etc. The component B is composed of polyisocyanate, polyol, multi-walled carbon nanotubes, a dispersant, etc. According to the present invention, the polyurethane has a reliable conductive function, the damaged conductive polyurethane material has self-healing performance under the condition of room temperature or illumination, and different hand feelings and different mechanical properties can be regulated and controlled by adjusting the microphase separation value HBI (0.5-3.0) of soft and hard segment molecules. The organic pollutant emission (VOCs) is lower than 50 mg/kg, and the polyurethane is green and environmentally-friendly, and has a good industrial application prospect.
