1820 results about "Self-healing" patented technology

Self-healing refers to the process of recovery (generally from psychological disturbances, trauma, etc.), motivated by and directed by the patient, guided often only by instinct. Such a process encounters mixed fortunes due to its amateur nature, although self-motivation is a major asset. The value of self-healing lies in its ability to be tailored to the unique experience and requirements of the individual. The process can be helped and accelerated with introspection techniques such as Meditation.

Self-healing polyurethane resin containing disulfide bond and preparation method thereof

InactiveCN105482065ARepair damageStrong performance controllabilitySelf-healingPolyester
The invention relates to self-healing polyurethane resin containing disulfide bond and a preparation method thereof. The polyurethane resin comprises, by weight parts, 10-30 parts of polyether or polyester polyol, 3-20 parts of polyisocyanates, 1-10 parts of chain extender containing the disulfide bond, 0.001-1 part of organic tin or tertiary amine catalyst and 50-80 parts of organic solvent. The method for preparing the self-healing polyurethane resin containing the disulfide bond comprises the steps of weighing raw materials, stirring, heating and performing dehydration for the polyether or polyester polyol under vacuum conditions, lowering the temperature to 85 DEG C or below, adding the polyisocyanates and the organic tin or tertiary amine catalyst, reacting, lowering the temperature to 50 DEG C or below, adding the organic solvent and the chain extender containing the disulfide bond, reacting and performing vacuum defoamation to obtain the self-healing polyurethane resin. The self-healing polyurethane resin heals by itself under the heating or ultraviolet (UV) light conditions, the required conditions are mild, the healing speed is high, the effect is good, the preparation method is simple and easy to control, and raw materials are goods of commercialized production and are cheap and easy to obtain.
