Abstract

The invention discloses a high-temperature-resistant and friction-resistant coating for automobiles. The high-temperature-resistant and friction-resistant coating is prepared from the following components in parts by weight: 80-100 parts of bisphenol A epoxy resin, 30-50 parts of acetone, 50-60 parts of a dicyandiamide curing agent and 60-90 parts of a high-temperature-resistant and friction-resistant filler prepared by taking polytetrafluoroethylene (PTEE) and polyether-ether-ketone (PEEK) as raw materials. The invention also discloses a preparation method of the high-temperature-resistant friction-resistant coating for automobiles, which comprises the following steps: preparing a high-temperature-resistant friction-resistant filler component, adding a part of the filler component into areaction kettle to react, and adding a curing agent into the reaction kettle to react, thereby obtaining the high-temperature-resistant and friction-resistant coating. According to the invention, through synchronous improvement of the formula and the process, the technical problem of poor compatibility among components in the use process of paint for automobile splines at present is solved, and the material strength is improved.

Description

technical field [0001] The invention relates to the technical field of high-temperature and friction-resistant coatings, in particular to a high-temperature and friction-resistant coating for automobiles and a preparation method thereof. Background technique [0002] Automotive coatings are one of the important chemical raw materials for the automotive industry, and their main purpose is to protect the substrate. The spline of the car is used in conjunction with the spline shaft and the spline sleeve. During the operation of the car, the two parts of the spline shaft and the spline sleeve are constantly rubbing against each other. In the process of mutual friction movement, the spline shaft and spline sleeve made of steel materials not only have greater friction and wear, but also increase the temperature caused by friction. The existence of the above problems will reduce the service life of the spline . [0003] In order to improve the service life of the spline, a layer ...
