Polyamide/polyketone alloy material

Abstract

The invention provides a polyamide / polyketone alloy material. The polyamide / polyketone alloy material comprises 55-85% of polyamide PA, 10-40% of polyketone POK, 0-10% of compatilizer, 0-3% of anti-wear agent, 0.3-1% of lubricant and 0.3-1% of compound heat stabilizer. The obtained polyamide / polyketone alloy material having excellent wear resistance is prepared through a double screw extruder; and the alloy material can be used for injection molding or extrusion molding material formed high-wear-resistance plastic components.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polyamide / polyketone alloy material. Background technique [0002] Polyamide is one of the five general-purpose engineering plastics. It has excellent mechanical properties and is widely used in electronic and electrical industries. It is often used as a component selection in electronic and electrical appliances. However, it has defects in some high-end or special applications, such as its wear resistance. Insufficient wear resistance, it is necessary to modify the wear resistance of polyamide, the literature records show that usually add wear additives, such as molybdenum disulfide, silane wear agent to improve the wear resistance of polyamide, there are also literature records, the polyamide Amides and resins with better wear resistance are made into alloys, such as PA / POM alloys, to improve the wear resistance of polyamides. Although the wear resistance can be improved by a...

[0002] Polyamide is one of the five general-purpose engineering plastics. It has excellent mechanical properties and is widely used in electronic and electrical industries. It is often used as a component selection in electronic and electrical appliances. However, it has defects in some high-end or special applications, such as its wear resistance. Insufficient wear resistance, it is necessary to modify the wear resistance of polyamide, the literature records show that usually add wear additives, such as molybdenum disulfide, silane wear agent to improve the wear resistance of polyamide, there are also literature records, the polyamide Amides and resins with better wear resistance are made into alloys, such as PA / POM alloys, to improve the wear resistance of polyamides. Although the wear resistance can be improved by adding wear-resistant additives, the wear-resistant additives It is expensive in itself, adding too much will lead to an excessive increase in cost, and the mechanical properties of the material will be reduced by one. PA / POM alloy improves the wear resistance of the material and will not increase the cost, but the compatibility of the two The problem needs to be solved, and at the same time, POM has the disadvantage of a strong irritating taste during the molding process, so an alloy material that is easier to solve, has better compatibility, better wear resistance, and is environmentally friendly
