Description
TECHNICAL FIELD
[0001] The present application relates to the field of high polymer alloy material modification, and in particular to a polyaryletherketone alloy material and a preparation method thereof. BACKGROUND
[0002] High-performance special polymer PAEK (polyaryletherketone) is a new type of semi-crystalline, thermoplastic aromatic polymer material, which is a high-performance and high-value thermoplastic special engineering plastic.
[0003] The main chain structure contains repeating units of ketone bonds, ether bonds and benzene rings, which endows the polyaryletherketone material with excellent mechanical properties, mechanical properties, heat resistance and mechanical properties. The flexibility of the ether bond and the intermolecular force of the ketone bond endow the polyaryletherketone material with chemical resistance and wear resistance, and the application field of the modified material is further expanded.
[0004] Therefore, polyaryletherketone materials have been widely used in aerospace, electronics, automobiles, energy, medical and other fields.
[0005] Polyether ether ketone (PEEK) material is an important variety in this material family, and the melting point of polyether ether ketone material is as high as 340℃, which can maintain high mechanical properties and mechanical properties at high temperature of 200℃ for a long time, and also has excellent chemical stability, high temperature thermal stability and biocompatibility.
[0006] Due to the high melting point of polyether ether ketone material, the processing temperature required is also relatively high, the processing temperature window is narrow, the requirement for processing equipment is high, and the energy consumption is large.
[0007] In order to improve the processing performance of PEEK, the existing technology often uses the method of adding low-viscosity, low-processing-temperature polymer materials (such as PEI / PPS / PSU / PESU / PPSU / PPA / LCP, etc.) or plasticizers.
[0008] However, these alloy material modification methods often sacrifice the heat resistance and mechanical properties of the material.
[0009] For example, adding too much low-melting-point component will cause the hot deformation temperature of the alloy to decrease significantly, thereby limiting the application of the alloy material in the field with strict requirements on heat resistance and mechanical properties.
[0010] On the other hand, crosslinking modification technology of polymer high molecular material is a very effective means to improve the heat resistance, mechanical properties and mechanical properties of polymer high molecular material. However, the completely crosslinked polymer high molecular material will lose thermoplasticity and cannot be subjected to melt processing such as injection molding or extrusion.
[0011] In the application fields of aerospace, electronics and electrical appliances, automobiles, energy, medical treatment and the like, some components have relatively high requirements on the heat resistance and mechanical properties of polymer materials, such as weight reduction of structural parts and reliability of structural parts.
[0012] Therefore, there is an urgent need in the art to prepare a polyaryletherketone alloy material, a new polyaryletherketone alloy material capable of balancing good processability and excellent terminal performance, so as to realize the balance between high-temperature performance, mechanical properties, mechanical properties and low-temperature processability. SUMMARY
[0013] The present application aims to develop a polyaryletherketone alloy material, an alloy material capable of balancing good high-temperature performance, mechanical properties and low-temperature processability.
[0014] The specific scheme is as follows: A polyaryletherketone alloy material, each component is calculated by weight parts, specifically including polyaryletherketone matrix resin content of 30-60 parts; low melting point polyaryletherketone (ZYPAEK-LC) matrix resin content of 10-91 parts; partially crosslinked polyaryletherketone matrix resin content of 8-40 parts, and the remaining parts are additives.
[0015] The additive includes antioxidant, lubricant, acid absorbent, nucleating agent and foaming agent.
[0016] The partially crosslinked polyaryletherketone matrix resin has a crosslinking degree of 20-90%, preferably a crosslinking degree of 40-70%, and more preferably a crosslinking degree of 50-60%.
[0017] The antioxidant includes primary antioxidant and auxiliary antioxidant, wherein the primary antioxidant is butyl hydroxytoluene 2,6-di-tert-butyl-p-cresol, and the auxiliary antioxidant is N,N'-bis-(β-naphthyl)-p-diamine.
[0018] The content ratio of the primary antioxidant to the auxiliary antioxidant is 3:4.
[0019] The lubricant is vinyl bis-stearamide.
[0020] The acid absorbent is calcium stearate and / or hydrotalcite.
[0021] Another aspect of the present application further provides a preparation method of the polyaryletherketone alloy material, comprising: S1, weighing the polyaryletherketone matrix resin, the low melting point polyaryletherketone matrix resin, the partially crosslinked polyaryletherketone matrix resin and the additive according to the proportion; S2, pre-mixing to ensure initial uniform dispersion; S3, feeding the pre-mixed material into an extruder for melt blending extrusion molding; S4, the extrusion product is cooled and shaped to obtain the required modified PAEK alloy material particles.
[0022] The extrusion temperature in S3 is 320-400 DEG C.
[0023] The mixture can also include toner.
[0024] The application also provides that the modified PAEK material alloy material can be applied to extrusion molding, injection molding, compression molding and the like.
[0025] The application has the following advantages: (1) By adjusting the material combination of each component of the polyaryletherketone 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.
[0026] (2) By adjusting the crosslinking degree and the amount of use of the partially crosslinked polyaryletherketone material, the application can be optimized and developed according to the application requirements, and the application field is widened.
[0027] (3) The existing polyaryletherketone (PAEK) processing equipment (extruder, injection molding machine) and processing technology have good applicability, and the industrialized production and application of the polyaryletherketone alloy material are easy to realize. DETAILED DESCRIPTION

[0110]
[0111] By comparing the reference cases and the implementation cases, it can be seen that the preparation scheme of polyaryletherketone alloy materials can ensure the balance of the flow properties, mechanical properties, thermal properties and other properties of polyaryletherketone alloy materials by adjusting the content of each component, different degrees of crosslinking and component content.
[0112] Through implementation cases, the following conclusions can be drawn: 1. While maintaining the fluidity, mechanical properties, and other properties of polyaryletherketone (PAEK) alloys, the melting temperature of PAEK alloys decreases significantly by nearly 10%, reducing the processing temperature and increasing the processing window of the alloys; 2. By reducing the fluidity of PAEK alloys, the mechanical properties and other properties of PAEK alloys are significantly improved, especially rigidity and toughness, with bending strength and bending modulus increasing by nearly 100% and impact strength increasing by 300%. At the same time, the melting temperature of PAEK alloys also decreases significantly, reducing the processing temperature and increasing the processing window of the alloys.
[0113] In summary, within a high-flow polyaryletherketone alloy system, this approach can significantly improve the mechanical properties and reduce the processing temperature of the alloy material when the addition amount is low and the degree of crosslinking is low; when the addition amount is high and the degree of crosslinking is high, this approach can appropriately reduce the flowability of the alloy material, significantly improve its mechanical properties and reduce the processing temperature.
[0114] In medium- and low-fluidity polyaryletherketone alloy systems, it significantly improves the material's flow properties, mechanical properties, and mechanical properties, while also significantly reducing the melting temperature of the alloy system and increasing the material's processing window.
[0115] This solution provides superior processing performance for injection molding and impregnation of composite materials, offering higher rigidity and impact strength at lower processing temperatures, thus meeting the demands of applications with more stringent material performance requirements.
