Description

Technical Field

[0001] This invention relates to the field of modified polymer alloy materials, specifically to a polyaryletherketone alloy material for wires and cables and its preparation method.

[0002] Suitable for special wires and cables used in aviation and aerospace sensors, high-temperature engine sensors, high-temperature metallurgical sensors, medical sensors, high-temperature nuclear power sensors, oilfield sensors, high-temperature chemical sensors, high-temperature energy exploration sensors, etc.; electromagnetic wires for motors, transformers, etc., especially suitable for high-voltage motors; optical fiber sheathing; nuclear power and other special fields. Background Technology

[0003] Polyaryletherketone (PAEK) is a novel semi-crystalline thermoplastic aromatic polymer material, a high-performance and high-value-added thermoplastic engineering plastic. Its main chain structure contains repeating units of ketone bonds, ether bonds, and benzene rings, which endow PAEK with excellent mechanical properties, heat resistance, wear resistance, and chemical resistance.

[0004] This allows for a variety of processing methods for polyaryletherketone (PAEK) materials, such as injection molding, extrusion, compression molding, spraying, 3D printing, wire drawing, calendering, and impregnation.

[0005] Polyetheretherketone (PEEK) is an important variety in the polyaryletherketone (PAEK) material family. PEEK has a melting point as high as 340℃ and can still be used for a long time at a high temperature of 200℃.

[0006] Polyetheretherketone (PEEK) materials have outstanding resistance to heat aging, excellent flame retardancy, self-extinguishing properties, hydrolysis resistance, corrosion resistance, peel resistance, fatigue resistance, and radiation resistance. They also have excellent electrical insulation properties and maintain a low dielectric constant and dielectric loss in the high-frequency range, making them widely used in the field of special wires and cables.

[0007] For example, with the development of new energy electric vehicles, thin-film polyetheretherketone (PEEK) electromagnetic wire has solved the problem of thick varnish mentioned in patent CN11155443B, including but not limited to the decrease in varnish flexibility, easy cracking of varnish during the winding of drive motor coils, and inability to meet the requirements of some drive motors for long-term use in harsh working environments (such as high-temperature environments); it meets the requirements of 800V architecture motors for wires and cables.

[0008] However, polyetheretherketone (PEEK) materials have high melting points and chemical stability, but they also require relatively high processing temperatures, have narrow processing temperature windows, high requirements for processing equipment, and high energy consumption.

[0009] Therefore, there is an urgent need in this field to prepare a polyaryletherketone (PAEK) alloy material for wires and cables, which has a lower processing temperature, a wider processing window, and superior processing and mechanical properties, thereby enabling the preparation of special wires and cables with polyaryletherketone (PAEK) alloy material as the matrix resin. Summary of the Invention

[0010] This invention aims to prepare a polyaryletherketone alloy material for special wires and cables, which has lower processing temperature, wider processing window, and superior processing and mechanical properties. It is suitable for special wires and cables used in aerospace sensors, high-temperature engine sensors, high-temperature metallurgical sensors, medical sensors, high-temperature nuclear power sensors, oilfield sensors, high-temperature chemical sensors, and high-temperature energy exploration sensors; electromagnetic wires for motors and transformers, especially suitable for high-voltage motors; optical fiber sheathing; and special fields such as nuclear power.

[0011] The specific plan is as follows: A polyaryletherketone (PAEK) alloy material for wires and cables, wherein each component, calculated by weight, specifically includes 19-42 parts of PAEK matrix resin; 20-40 parts of low-melting-point PAEK (ZYPAEK-LC) matrix resin; 17-60 parts of partially cross-linked PAEK matrix resin; and the remaining parts are additives.

[0012] The additives include antioxidants, lubricants, and acid absorbers required in the preparation of alloy materials.

[0013] The partially cross-linked polyaryletherketone (PAEK) matrix resin is preferably a partially cross-linked polyetheretherketone (PEEK) matrix resin.

[0014] The partially crosslinked polyaryletherketone (PAEK) matrix resin has a crosslinking degree of 20-90%, preferably 40-70%, and more preferably 50-60%.

[0015] The antioxidant includes a primary antioxidant and a secondary antioxidant, wherein the primary antioxidant is butylated hydroxytoluene 2,6-di-tert-butyl-p-cresol and the secondary antioxidant is N,N'-bis-(β-naphthyl)-p-diamine.

[0016] The ratio of the primary antioxidant to the secondary antioxidant is 3:4.

[0017] The lubricant is vinyl bis-stearamide.

[0018] The acid absorbent is calcium stearate and / or hydrotalcite.

[0019] Another aspect of the present invention provides a method for preparing a polyaryletherketone (PAEK) alloy material for wires and cables, comprising: S1. Weigh the polyaryletherketone (PAEK) matrix resin, low-melting-point polyaryletherketone (PAEK) matrix resin, partially crosslinked polyaryletherketone (PAEK) matrix resin and additives in proportion. S2. Perform premixing to ensure initial uniform dispersion; S3. The premixed material is fed into an extruder for melt blending and extrusion molding; S4. After the extruded product is cooled and shaped, the desired polyaryletherketone (PAEK) alloy material particles are obtained.

[0020] The extrusion temperature in S3 is 320℃~400℃.

[0021] The degree of crosslinking of the polyaryletherketone (PAEK) alloy material obtained in S4 ranges from 10% to 35%.

[0022] The polyaryletherketone (PAEK) alloy material mixture may also include color powder.

[0023] The modified alloy material obtained by this invention can be applied to the preparation of wires and cables.

[0024] The beneficial effects of this invention are as follows: (1) By adjusting the material combination of each component of polyaryletherketone (PAEK) alloy material, the alloy material has a wider material processing window; at the same time, it has good mechanical properties, mechanical properties and thermal properties.

[0025] (2) By adjusting the degree of crosslinking and the amount of crosslinked polyaryletherketone (PAEK) material, the wires and cables of PAEK flat wires have higher breakdown voltage (BDV) and partial discharge initiation voltage (PDIV).

[0026] (3) It has good applicability to various existing polyarylether ketone (PAEK) processing equipment and processes for wires and cables, and it is easy to realize the industrial production and application of wires and cables with polyarylether ketone (PAEK) alloy material as the matrix resin.
