Problems solved by technology

However, since POM is a highly crystalline engineering plastic (the crystallinity is generally as high as 70% to 85%), the size of the spherulites is large, resulting in high notch sensitivity, poor toughness, and low notched impact strength. When applied to outdoor products, Poor long-term weather resistance greatly limits the application and development in various fields

Abstract

The invention discloses an aging-resistant high-toughness polyformaldehyde material and a preparation method thereof, and relates to the technical field of high polymer materials, the aging-resistanthigh-toughness polyformaldehyde material comprises the following components by mass: 80-95% of polyformaldehyde resin (POM); 1%-20% of a toughening agent; 0.2-1% of an antioxidant; 0.1%-2% of an anti-UV agent; and 0.2%-1% of a nucleating agent. The aging-resistant high-toughness polyformaldehyde resin material has the advantages of high toughness, excellent aging resistance and favorable mechanical properties, can satisfy the requirements of outdoor products for external environment resistance, and is suitable for manufacturing antifriction wear-resistant parts, transmission parts, chemical engineering, instruments and other parts.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an aging-resistant and high-toughness polyoxymethylene material and a preparation method. Background technique [0002] Polyoxymethylene resin, (polyformaldehyde, abbreviated as POM), also known as acetal resin, is a linear thermoplastic general engineering plastic without side chains, high density and high crystallinity. Smooth, shiny, high strength, low water absorption, dimensional stability, high rigidity, high creep resistance, high fatigue resistance, especially excellent friction resistance, among the five general plastics, its annual output is second only to nylon (PA) and polycarbonate (PC), ranked third. Because POM has excellent strength and rigidity, good corrosion resistance, wear resistance and self-lubrication, outstanding fatigue resistance and good creep resistance, it is one of the resin varieties with mechanical properties closest to metal among engi...
