Abstract

The invention relates to organic complex composite phenolic resin of nickel and a preparation method of the organic complex composite phenolic resin. According to the technical scheme, the preparation method comprises the following steps of: adding an organic complex of the nickel into phenolic resin diluted by absolute ethanol, wherein according to the addition amount, a mass ratio of a nickel element in the organic complex of the nickel to the nickel in phenolic resin diluted by the absolute ethanol is (0.001-0.05):1; stirring at the temperature of between 20 and 60 DEG C for 1 to 6 hours; and putting into an evaporator, and distilling at the temperature of between 30 and 60 DEG C under the pressure of between 0.08 and 0.09 MPa for 0.5 to 4 hours to obtain the organic complex composite phenolic resin of the nickel. Compared with simple substance or compound composite phenolic resin of other transition metal elements and a preparation method, the invention has the advantages that theproduction cost is low; and the organic complex composite phenolic resin of the nickel is high in dispersity, residual carbon rate and oxidation resistance. The prepared organic complex composite phenolic resin of the nickel is used as a bonding agent to prepare a carbon composite refractory, so that the breaking strength at normal temperature is improved obviously.

Description

technical field [0001] The invention belongs to the technical field of composite phenolic resins, and in particular relates to a nickel organic complex composite phenolic resin and a preparation method thereof. Background technique [0002] Phenolic resin is the most commonly used binder for carbon composite refractories. As a carbon composite refractory binder, phenolic resin has the advantages of high thermohardness, high drying strength and less environmental pollution compared with tar pitch binder. However, it has the defects of low residual carbon rate, low degree of graphitization of pyrolytic carbon and poor oxidation resistance, which leads to low strength of carbon composite refractories in the medium temperature region. [0003] At present, compound phenolic resins are prepared by adding transition metal iron, cobalt or nickel or their compounds to phenolic resins, which improves the residual carbon rate of ordinary phenolic resins, the degree of graphitization o...
