An oil-containing self-lubricating material and its application

Abstract

The invention provides an oil-containing self-lubricating material and an application thereof, belonging to the technical field of oil-containing self-lubricating 3D printing polymer materials. The oil-containing self-lubricating material provided by the present invention comprises a matrix material, lipophilic filler and lubricating oil; the mass ratio of the matrix material, lipophilic filler and lubricating oil is 100:(0.1-50):(0.1-50). In the oil-containing self-lubricating material provided by the present invention, the matrix material droplets are surrounded by lipophilic fillers, which can stabilize the oil droplets and improve their mechanical properties; Self-lubricating properties of lubricating materials; by controlling the mass ratio of matrix materials, lipophilic fillers, and lubricating oils, it is more conducive to improve the stability of emulsions, improve printing accuracy, and effectively improve the mechanical properties of oil-containing self-lubricating materials after curing.

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 an application thereof. Background technique [0002] The manufacturing method of oil-containing self-lubricating materials is generally to first manufacture porous polymer materials, and then use the porosity of the materials to pour lubricating oil into the polymer through-hole structure under vacuum conditions, so as to achieve a solid-liquid composite self-lubricating material. Purpose. However, this method has certain limitations: first, the preparation process of porous materials is cumbersome, and a large number of through-hole structures lead to a great decrease in the integrity of the material; second, in the use of lubricating parts, the lubricating oil in the material system will Slowly flowing out of the through-hole structure, the loss of lubricating oil results in ...

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.
