Bionic microcapsule containing molybdenum disulfide and preparing method and application of microcapsule

Abstract

The invention discloses a bionic microcapsule containing molybdenum disulfide and a preparing method and application of the microcapsule. The bionic microcapsule comprises a core material and a wall material. The core material is wrapped in the wall material through an emulsion reaction of molybdenum disulfide. Urea resin is adopted as the wall material. Methylbenzene is used as an external waterphase, a urea resin prepolymer and a molybdenum disulfide suspension are slowly added to the external water phase for an emulsion reaction, and pH is controlled to be 3-3.8; after the reaction ends, centrifugal separation, cleaning and drying are conducted to obtain the bionic microcapsule. The invention further discloses a water lubricated bearing bionic material which is prepared by mixing the bionic microcapsule containing molybdenum disulfide with a high polymer substrate material. The obtained water lubricated bearing bionic material has wear resistance to a certain extent; meanwhile, itis avoided that when a composite is prepared, the compatibility difference of different materials is quite large, the composite is prone to cracks, additives are prone to leakage and filling lubricants can hardly have lubricating and wear reduction functions under the extreme conditions.

Description

technical field [0001] The invention belongs to the technical field of composite polymer materials, and mainly relates to a bionic microcapsule and a preparation method thereof. Background technique [0002] Water-lubricated stern bearings have been used on ships since the middle of the 19th century. At the beginning, metals were used to make water-lubricated stern bearings. However, due to the corrosiveness of water media, especially seawater, and the electrochemical Corrosion makes the metal corrosion of the stern bearing very serious and accompanied by greater wear. [0003] Iron plow wood materials have been used in ship stern bearings since the middle of the 19th century. Through research, it has been found that resin, resin essence, hard resin and bitter essence, the self-lubricating properties of iron plow wood materials and the transformation of resin and essence Closely related, on the one hand, the resin stored in the gap is squeezed out of the gap under the actio...
