Preparation method of soundproofing and lubricating functional material

The invention discloses a preparation method of a soundproofing and lubricating functional material, and belongs to the field of material preparation. The method comprises the steps: adding polyformaldehyde resin, a main lubricant, a co-lubricant, a wear-resisting agent, a friction reducing agent, a silencing agent, a formaldehyde absorbent, an antioxidant and an anti-UV absorber into a high-speed mixing machine, mixing evenly, then adding the mixture into a hopper, continuously metering and feeding into a double-screw extruder, then heating, shearing, compressing, melting, plasticizing, cooling, and sized-dicing to obtain the material. The extruded particles are dried and subjected to injection molding to form the soundproofing and lubricating functional material. The functional material prepared by the method has the characteristics of excellent lubrication performance, wear resistance, weather resistance, low moisture absorption, excellent soundproofing performance and the like, can be widely applied in ma
