Abstract

The invention pertains to the plastic product and the profile field thereof, and in particular relates to a method to prepare a PEEK bar by means of extrusion molding. PEEK is put into the feed hopper of an extruder, and is fused to plasticize in the extruder barrel below the degree of 360-400 DEG C, so as to form PEEK melt, which is extruded out by the nose and rod dies. Under the role of back pressure rods with constantly reverse pressure, the melt enters into and permeates the Rod Dies, and then enters into the sizing sets linking with the Rod Dies; The melt goes on formation of products by echelon cooling gradually in the sizing sets, thus the PEEK bar is made. Then the bar is treated by the way of echelon annealing in a tube-type annealing furnace, at last the good crystallized PEEK bar with excellent size stability and against bending is obtained. The PEEK bar produced by the invention is used to the fields of aerospace, electronic and electrical engineering, cars, chemicals, as well as machine, etc., and is used to process all kinds of parts and products needed in these fields.

Description

technical field

[0001] The invention belongs to the field of plastic products and profiles thereof, and in particular relates to a method for preparing a polyether ether ketone resin rod through an extrusion molding method. Background technique

[0002] Polyether ether ketone resin has the characteristics of high heat resistance, radiation resistance, high impact strength, good wear resistance and fatigue resistance, flame retardancy, and excellent electrical properties. Since its commercialization, it has been widely used in aerospace, automotive, electrical and electronic, chemical, mechanical and medical fields. Polyether ether ketone products used in the above fields are generally manufactured by injection molding, but some products are subject to many molds and high production costs due to their large size and different shapes. However, many users need to use semi-finished products such as polyether ether ketone rods, profiles, plates and sheets to manufacture the requ...
