Abstract

The invention provides a sound-attenuating and wear-resistant polyformaldehyde material. The material comprises the following components in percentage by weight: 55 to 75 percent of polyformaldehyde resin, 5 to 10 percent of low density polyethylene, 3 to 10 percent of toughening agent, 10 to 20 percent of polytetrafluoroethylene, 2 to 5 percent of compatilizer, 0.2 to 0.4 percent of antioxidant, 0.2 to 0.6 percent of lubricating agent and 0.2 to 0.6 percent of aldehyde absorbing agent. The invention also provides a method for preparing the sound-attenuating and wear-resistant polyformaldehyde material. The sound-attenuating and wear-resistant polyformaldehyde material has high strength, dimensional stability, creep resistance, fatigue resistance, and high self-lubricating property, sound-attenuating property and wear resistance; and the preparation method for the material is simple, convenient to operate, high in benefit, low in cost and suitable for industrial production.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to a sound-absorbing and wear-resistant polyoxymethylene material and a preparation method thereof. Background technique

[0002] As one of the five major engineering plastics, POM (polyoxymethylene) resin is one of the most widely used polymers. It belongs to thermoplastic crystalline polymers, does not contain side chains, high density, high crystalline linear polymers, and has excellent comprehensive properties. performance.

[0003] Polyoxymethylene is a hard and dense material with smooth surface and luster, which can be used for a long time in the temperature range of -40 ~ 100 ℃. Its wear resistance and self-lubrication are also superior to most engineering plastics, high tensile bending strength, low water absorption, stable size, high rigidity, creep resistance, high fatigue resistance, etc., especially suitable for manufacturing gears and bearings ....
