Problems solved by technology

[0002] Electromagnetic induction heating roller is a high-end heating roller prepared according to the principle of electromagnetic induction heating metal. Compared with traditional heat conduction oil heating roller and electric heating roller , has the advantages of high temperature, good temperature uniformity, low energy consumption, and no pollution. It is widely used in the field of calendering and shaping of various sheets, but there is a risk of adhesion to the roll surface when the polymer material is melted at high temperature. Therefore, how to ensure the processing quality of the roller surface has become the primary technical problem to be solved at present.
[0003] In the related technology, organic polytetrafluoroethylene coating is applied on the roller surface to realize the protective effect on the roller surface, which can effectively prevent the adhesion of polymer materials to the roller surface, but the organic polytetrafluoroethylene coating formed by the above treatment steps has poor bonding force and strength with the metal substrate, and is easy to fall off due to external force, and the wear resistance of the organic coating is poor. The coating structure is easily damaged by sharp objects, which in turn affects the processing quality of the product

Abstract

The invention relates to the technical field of metal surface treatment, in particular to a wear-resistant anti-adhesion coating as well as a preparation method and application thereof. The wear-resistant anti-adhesion coating comprises the following components in parts by weight: 80-100 parts of silicon carbide; 10 to 20 parts of a sintering aid; 10 to 15 parts of a binder; 5-8 parts of titanium calcium aluminate; 2-3 parts of titanium dioxide; and 0.5-1 part of zirconium silicide. According to the coating composed of silicon carbide, titanium calcium aluminate, titanium dioxide and zirconium silicide, after the coating is cured on the roller surface of the heating roller to form a ceramic protective layer, the roller surface is endowed with excellent hardness and dustproof performance through the characteristics of the coating, the binding force and strength of the coating and a metal matrix are remarkably enhanced, and the coating is not prone to falling off.

Description

technical field [0001] The application relates to the technical field of metal surface treatment, more specifically, it relates to a wear-resistant and anti-adhesion coating, its preparation method and application. Background technique [0002] Electromagnetic induction heating roller is a high-end heating roller prepared according to the principle of electromagnetic induction heating metal. Compared with traditional thermal oil heating rollers and electric heating rollers, it has high temperature, good temperature uniformity, low energy consumption, and no heating. Pollution and other advantages are widely used in the calendering and shaping fields of various sheets, but polymer materials melt at high temperatures and there is a risk of sticking to the roller surface, so how to ensure the processing quality of the roller surface has become the primary solution at present technical problems. [0003] In the related art, the roll surface is coated with an organic polytetrafl...
