Problems solved by technology

However, the C-C covalent bond of graphite itself makes it a typical hydrophobic material, which cannot be well compounded with the hydrophilic matrix, and its too large scale cannot be used as a large amount of filling material.
Therefore, it is still very challenging to develop high-performance hydrophilic self-lubricating materials.

Abstract

The invention relates to hydrophilic self-lubrication microspheres, a preparation method therefor and an application of the hydrophilic self-lubrication microspheres. The hydrophilic self-lubrication microspheres contain the following ingredients in percentage by mass: 80% to 99% of styrene-acrylamide copolymer microspheres and 0.5% to 20% of sulfonated graphene, wherein the particle size of nano particles is 200nm to 50 microns. The hydrophilic self-lubrication microspheres, the preparation method therefor and the application of the hydrophilic self-lubrication microspheres have the following advantages that a styrene-acrylamide copolymer microsphere matrix is controllable in size and wide in applicable range and can be used for constructing microsphere structures of different sizes; the sulfonated graphene and the styrene-acrylamide copolymer microspheres are subjected to self-assembly compounding, and hydrophilic groups of surfaces of the microspheres and the sulfonated graphene on surface layers are in synergism, so that lubricating and hydrophilic effects are more superior, and the wear resistance and durability are more outstanding; and an aqueous self-lubricating material has the characteristics of safety and environment-friendliness and has a huge market prospect.

Description

technical field [0001] The invention relates to a functional microsphere, in particular to a hydrophilic self-lubricating microsphere and its preparation method and application. Background technique [0002] Self-lubricating functional materials are important raw materials in the fields of composite materials, functional coatings, composite films, etc., and play an important role in keeping surfaces clean, anti-sticking, and release. Among them, the hydrophilic self-lubricating technology maintains the continuous hydrophilicity of the surface of the object, and the surface pollutants are easily washed away by water, so that it has the function of self-cleaning. The conventional approach is to increase the density of surface hydrophilic groups, such as hydroxyl, carboxyl, amino, etc., or surfactants. However, the biggest problem with this type of self-lubricating material is continuous hydrophilicity. Due to the poor wear resistance of the polymer itself, it will cause large...
