Abstract

The invention provides a phenol aldehyde resin which is prepared by reacting phenol compounds, aldehyde compounds and graphene, wherein the mole ratio of the phenol compounds to the aldehyde compounds is 1:(1.0-2.5), and the mass ratio of the graphene to the phenol compounds is (0.01-2):100. The invention provides a preparation method of the phenol aldehyde resin, which comprises the following steps: carrying out first reaction on the phenol compounds, an alkaline catalyst, the aldehyde compounds and the graphene to obtain a reaction product, wherein the temperature of the first reaction is 60-90 DEG C; and carrying out second reaction on the reaction product and alcohol compounds to obtain the phenol aldehyde resin. The invention also provides an automobile filter paper prepared from the phenol aldehyde resin in the technical scheme, or prepared from the phenol aldehyde resin prepared by the method in the technical scheme. The phenol aldehyde resin provided by the invention comprises graphene, and thus, has favorable electric conductivity.

Description

technical field [0001] The invention relates to the technical field of resins, in particular to a phenolic resin, a preparation method thereof, and an automobile filter paper. Background technique [0002] Automotive filter paper is the general term for air filter paper, oil filter paper and fuel filter paper. The main purpose of automotive filter paper is to filter the dust and impurities in the engine intake, oil and fuel, and reduce the wear and tear of dust and impurities on the key components of the engine. The automobile filter paper prepared by phenolic resin has good toughness and stiffness. Car filter paper is usually non-conductive, but during the fuel delivery process of the car, the high-speed and severe friction between the fuel and the delivery pipeline will generate a large amount of static electricity, which accumulates on the metal parts of the delivery pipeline, and local static electricity The accumulation of charge will form a large potential difference...
