Problems solved by technology

[0003] However, phenolic resin itself does not have self-lubricating effect. Compared with graphite, molybdenum disulfide and other solid lubricants with self-lubricating effect, the friction coefficient is very high, which is the main cause of mechanical wear of materials.

Abstract

This invention involves a naphthol modified phenolic resin and its preparation. The ratio of the components : Phenol 100, solid paraform 40 - 45, polyphenylene oxide ether10- 15, modifier X 10-15, fiberglass 55 - 60, polysulfone 10 - 20, while sodium pentachlorophenate 2 -5, solvents 94 -100. Through the stir conditions adding modifier X into phenol, adding certain proportion of the solid paraform and polysulfone. In reactor adding solvents, resin diluted, and joined the sodium pentachlorophenate; fiberglass couple treated then uniform impregnation, after drying, postbaking, processing pelletizing and molding.

Description

Technical field: [0001] The invention relates to a polyphenylene ether modified phenolic resin and a preparation method thereof, which is mainly prepared by using phenol, polyphenylene ether, modifier X, solid paraformaldehyde, a catalyst and a toughening agent as raw materials. This kind of phenolic molding compound can be used to prepare wear-resistant, high-temperature-resistant and insulating structural parts. Background technique: [0002] At present, in many fields, it is necessary to use phenolic resin. It can be used in the manufacture of molding compounds, laminated plastics, foamed plastics, cellular plastics, various composite materials, adhesives, coatings, ion exchange resins, etc. Phenolic plastics are cheap, easy to obtain raw materials, and have good comprehensive performance. [0003] However, phenolic resin itself does not have self-lubricating effect. Compared with solid lubricants with self-lubricating effect such as graphite and molybdenum disulfide, t...
