Problems solved by technology

[0005] Due to its unique properties, polyether ether ketone has been widely used, but now it is limited in some special industries due to its poor rigidity.
Steel also has defects such as poor corrosion resistance, fast heat transfer, non-wear resistance, and large specificity. Therefore, it is necessary to combine the two to give full play to its main advantages and provide a composite plate with excellent materials for industrial production.

Abstract

The invention relates to a steel-base polyether-ether-ketone composite plate and a manufacturing method thereof, which belong to engineering plastics and metal composite plates and the field of manufacture of the engineering plastics and the metal composite plates. The composite plate is made of fiber reinforcement polyether-ether-ketone powder and a steel base plate, and the composite plate is manufactured by means of mold pressing by the aid of a mold in a molding process. The manufacturing method is simple, requirements on equipment are low, production conditions are easy to be met and controlled, and the manufactured plate is fine in stability and processing manufacturability and high in adhesion, and can be widely applied to required corrosion-resistant and abrasion-resistant slide plates in high-temperature and high-pressure environments in industries of petroleum, aviation, chemical engineering, automobiles, electronics, manufacture and the like.

Description

technical field [0001] The invention belongs to the field of engineering plastics and metal composite boards and their preparation, in particular to a composite board with polyetheretherketone and steel plates as main raw materials and a preparation method thereof. Background technique [0002] Polyetheretherketone has the following excellent properties: [0003] (1) High temperature resistance: PEEK resin has a high glass transition temperature (143°C) and melting point (334°C), which is one of the reasons why it can be used reliably in applications requiring heat resistance. Its thermal deformation temperature under load is as high as 316°C (30% GF or CF reinforced grade), and its continuous use temperature is 260°C; (2) Mechanical properties: PEEK resin is a plastic with a balance of toughness and rigidity. In particular, its excellent fatigue resistance to alternating stress is the most outstanding of all plastics, comparable to alloy materials; (3) Self-lubricating (c...
