Problems solved by technology

However, simply using ethylene oxide as the spring steel coating still has disadvantages such as poor wear resistance, low adhesion, and poor temperature resistance.
[0004] The thermal stability of polytetrafluoroethylene is the most prominent. Although it begins to decompose in a trace amount above 200°C, its decomposition rate is very slow and the amount of decomposition is very small in the temperature range from 200°C to above the melting point.

Abstract

The invention relates to an abrasion-resistant coating for an automobile spring steel plate and a preparation method of abrasion-resistant coating and belongs to the field of abrasion-resistant coating. According to the abrasion-resistant coating, tetrafluoroethylene latex is synthesized by virtue of a micro-emulsion method, the synthesized tetrafluoroethylene latex has the advantages of small grain size, good dispersibility, good stability and the like and is conductive to applying the coating; by adding a nanometer powder material, the corrosion resistance and abrasion resistance of the epoxy resin coating can be increased; sodium polyacrylate and sodium polycarboxylate used in a dispersant have good nanometer powder dispersing effects; by adding sodium tripolyphosphate, the stable dispersion of the polymer latex is facilitated; the stability and dispersibility of the coating are increased through the synergistic effect of sodium polyacrylate, sodium polycarboxylate and sodium tripolyphosphate; components of a curing agent have the advantage of room temperature curing so that the curing process is simple; the abrasion-resistant coating for the automobile spring steel plate disclosed by the invention is simple in process and convenient to operate and is conducive to large-scale industrial production.

Description

technical field [0001] The invention relates to a preparation method of a wear-resistant paint, in particular to a wear-resistant paint used for automobile spring steel plates and a preparation method thereof. Background technique [0002] Vehicle spring steel plate, also known as leaf spring, is a kind of elastic element widely used in automobile suspension. It consists of a number of spring steel sheets with different lengths, different radii of curvature, and equal or different thicknesses stacked together to form an elastic beam with approximately equal strength. The spring steel plate is deformed under the action of load, and friction is generated between the plates due to relative sliding, which can attenuate the vibration of the frame. There is dry friction between each piece, and at the same time, the impact force of the wheel is transmitted to the frame, which increases the wear of each piece. Therefore, when assembling, each piece of spring steel plate must be coa...
