Antistatic polyformaldehyde resin

Abstract

The invention discloses antistatic polyformaldehyde resin. The antistatic polyformaldehyde resin is prepared from the following components in parts by weight: 55 to 85 parts of polyformaldehyde, 2 to8 parts of antistatic agent, 1 to 4 parts of conductive fibers, 15 to 25 parts of polytetrafluoroethylene, 3 to 5 parts of white carbon black, 3 to 5 parts of vinyl silicone oil, 5 to 8 parts of polyether modified silicone oil and 4 to 10 parts of compatilizer. According to the antistatic polyformaldehyde resin disclosed by the invention, the antistatic agent is added to improve the antistatic performance of the polyformaldehyde resin; meanwhile, the conductive fibers and polytetrafluoroethylene are added to carry out further improvement, so that the electrical conductivity and tensile strength of polyformaldehyde are increased; polytetrafluoroethylene is added so that the wear resistance is good; the white carbon black and the vinyl silicone oil are used as reinforcing filler and can be combined with polyformaldehyde very well under the action of the compatilizer; furthermore, the strength of a polyformaldehyde finished product is improved.

Description

Technical field [0001] The invention relates to polymer engineering plastics, more specifically, it relates to an antistatic polyoxymethylene resin. Background technique [0002] Polyoxymethylene (POM) is a kind of engineering plastics with excellent comprehensive performance. It is widely used in industries such as automobiles, electronic appliances, household appliances, machinery and building materials, and because POM has excellent friction and wear characteristics, it can be used as gears, pulleys, Various power transmission transmission components such as slides or slides are also used more and more widely, so the electrostatic charge generated by these components due to friction will also cause various accidental damages. [0003] Moreover, due to the excellent electrical insulation of POM itself, it is easy to cause the accumulation of electric charge. Therefore, the POM used in the above-mentioned fields requires a certain degree of antistatic modification. On the other ha...

[0003] Moreover, due to the excellent electrical insulation of POM itself, it is easy to cause the accumulation of charges, so the POM used in the above fields requires a certain degree of antistatic modification. On the other hand, due to the thermal stability of POM itself Poor, commonly used low-surfactant antistatic agents have strong polarity, which can easily cause POM to decompose violently during molding processing. Often, even if the finished product has a certain antistatic property, it has poor performance in terms of self-strength and other aspects. declined
