Problems solved by technology

However, this method has certain limitations: first, the preparation process of the porous material is cumbersome, and a large number of through-hole structures lead to a great reduction in the integrity of the material; second, in the use of lubricating parts, the lubricating oil in the material system will Slow flow out from the through-hole structure, the loss of lubricating oil leads to shortened service life of lubricating parts
However, the disadvantages of this method are that the preparation process of microcapsules is complicated and the yield is low, agglomeration is easy to occur in the matrix, the stability is poor, and the mechanical properties are low, so it cannot be applied on a large scale at present.
At the same time, due to the high requirements of the preparation process of traditional oil-containing self-lubricating materials, there are still great restrictions on the manufacture of complex structures.

Abstract

The invention provides an oil-containing self-lubricating material and application thereof, and belongs to the technical field of oil-containing self-lubricating 3D printing polymer materials. The oil-containing self-lubricating material provided by the invention comprises a base material, an oleophylic filler and lubricating oil, the mass ratio of the base material to the oleophylic filler to the lubricating oil is 100: (0.1-50): (0.1-50). According to the oil-containing self-lubricating material provided by the invention, the periphery of the liquid drops of the base material is coated with the oleophylic filler, so that the effects of stabilizing the oil drops and improving the mechanical property of the oil drops can be achieved; the self-lubricating property of the oil-containing self-lubricating material can be effectively improved by filling the micro oil drops into the base material; and by controlling the mass ratio of the base material, the oleophylic filler and the lubricating oil, the stability of the emulsion is improved, the printing precision is improved, and meanwhile, the mechanical property of the oil-containing self-lubricating material after curing is effectively improved.

Description

technical field [0001] The invention relates to the technical field of oil-containing self-lubricating 3D printing polymer materials, in particular to an oil-containing self-lubricating material and its application. Background technique [0002] The manufacturing method of oil-containing self-lubricating materials is generally to manufacture polymer porous materials first, and then use the porosity of the material to pour lubricating oil into the polymer through-hole structure under vacuum conditions to achieve the goal of preparing solid-liquid composite self-lubricating materials. Purpose. However, this method has certain limitations: first, the preparation process of the porous material is cumbersome, and a large number of through-hole structures lead to a great reduction in the integrity of the material; second, in the use of lubricating parts, the lubricating oil in the material system will Slowly flowing out from the through-hole structure, the loss of lubricating oil...
