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.

preparation example Construction

[0038] The present invention also provides the method for preparing the oil-containing self-lubricating material according to the above technical solution, preferably comprising: mixing and defoaming the matrix material, the lipophilic filler and the lubricating oil in sequence to obtain the oil-containing self-lubricating material.

[0039] In the present invention, the matrix material, the lipophilic filler and the lubricating oil are preferably mixed to obtain a prefabricated oil-containing self-lubricating material.

[0040] In the present invention, the mixing sequence is preferably such that the lipophilic filler is added to the base material first, and then the lubricating oil is added. In the present invention, by controlling the mixing sequence, the surface of the micro-oil droplets can be coated with lipophilic fillers, which is more conducive to improving the stability of the oil-containing self-lubricating material.

[0041]In the present invention, the mixing oper...

Embodiment 1

[0060] The oil-containing self-lubricating material of this embodiment is composed of a matrix material, lipophilic filler and lubricating oil; the mass ratio of matrix material, lipophilic filler and lubricating oil is 100:10:5;

[0061] Among them, the matrix material is 3D printing cyanate ester liquid photosensitive ink with a viscosity of 45mPa.s, specifically 100g; the lipophilic filler is silica with a particle size of 50nm, specifically 10g; the lubricating oil is liquid paraffin, specifically 5g .

[0062] The above-mentioned preparation method of the oil-containing self-lubricating material is as follows: the matrix material is first mixed with the lipophilic filler, and then the lubricating oil is added for mixing, and then dispersed and defoamed to obtain the oil-containing self-lubricating material;

[0063] The mixing operation was ball milling, the ball milling speed was 3000 rpm, and the ball milling time was 9 min; the mixing temperature was 30° C.; and the de...

Embodiment 2

[0067] The mass ratio of the base material, lipophilic filler (silica), and lubricating oil in Example 1 was replaced with 100:5:5, and other technical features were the same as those in Example 1.

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 ...
