Description
Technical Field
The invention belongs to the technical field of preparation of high polymer materials, and particularly relates to a preparation method of an environment-friendly wear-resistant high polymer material.
Background
With the rapid development of modern industry, the application of polymer materials is more and more extensive, and polymer material research centers are set in all universities and research institutes, wherein the polymer materials are also called polymers, and are materials formed by taking polymer compounds as substrates and matching with other additives. The synthetic polymer material has superior performance, lower density, higher mechanics, wear resistance, corrosion resistance, electrical insulation and the like which are not possessed by natural polymer materials.
The existing polymer-based wear-resistant composite material takes thermoplastic or thermosetting resin as a matrix, and has good wear resistance by adding an organic or inorganic anti-friction component and an anti-wear reinforcing component, and the wear-resistant composite material adopting the polymer as the matrix has a series of excellent characteristics of antifriction self-lubrication, wear resistance, corrosion resistance, shock absorption, vibration reduction, noise reduction, small relative density, specific strength, simple and convenient processing and the like, and is widely used in the industries of electronics, automobiles, buildings, office equipment, machinery, aerospace and the like, but the strength, the impact resistance, the wear resistance and the environmental protection of the existing traditional polymer-based wear-resistant composite material are difficult to meet the market demand.
Disclosure of Invention
The invention aims to provide a preparation method of an environment-friendly wear-resistant high polymer material.
The technical problems to be solved by the invention are as follows:
in the prior art, the wear resistance of a polymer matrix is poor, the surface layer often falls off along with the increase of the service life, and most of the existing wear-resistant high polymer materials contain low-toxicity substances such as polytetrafluoroethylene and the like, so that the environment is polluted and the human health is harmed.
The purpose of the invention can be realized by the following technical scheme:
a preparation method of an environment-friendly wear-resistant high polymer material comprises the following steps:
firstly, preparing the following raw materials in parts by weight: 40-50 parts of PC resin, 20-30 parts of polyethylene terephthalate, 10-20 parts of polyamide resin, 5-10 parts of nano filler, 3-5 parts of modified aerogel, 3-5 parts of chopped carbon fiber, 1-3 parts of aluminum borate whisker, 2-3 parts of compatilizer, 6-8 parts of antioxidant and 0.5-1 part of lubricant for later use;
secondly, adding the PC resin, the polyethylene terephthalate and the polyamide resin into a stirring tank, and stirring for 30-60min at the temperature of 290-;
and thirdly, adding the nano filler, the modified aerogel, the chopped carbon fiber and the aluminum borate whisker into the base material obtained in the second step, stirring for 20min under the condition that the temperature and the rotating speed are the same as those in the second step, then adding the compatilizer, the antioxidant and the lubricant, reducing the rotating speed to 200-phase-change at 300r/min, reacting for 20min to obtain a mixed material, extruding and granulating the mixed material through a double-screw extruder, wherein the processing temperature of the double-screw extruder is 230-phase-change at 250 ℃, and the rotating speed of a host machine is 370-phase-change at 410 r/min.
Further, the preparation method of the nano filler comprises the following steps:
step S11, soaking natural graphite flakes in a hydrochloric acid solution with the volume fraction of 15% for 10-20min, filtering, washing filter cakes with deionized water until washing liquid is neutral, drying in a drying oven at the temperature of 100-;
step S12, adding distilled water and hydrogen peroxide into the mixture A obtained in the step S11, increasing the rotating speed to 500-;
