Abstract
The invention provides a graphite product anti-oxidant, which comprises the following components: 15-30 parts of silicon powder, 10-20 parts of phosphoric acid, 2-10 parts of boric acid, 3-10 parts of silicon carbide, 20-30 parts of silicon dioxide, 5-10 parts of magnesium oxide, 5-10 parts of sodium oxide, 2-5 parts of borax, 1-5 parts of sodium pyrophosphate and 0.5-2 parts of acrylic acid. According to the invention, combination of the anti-oxidant and the graphite product is tight, antioxidation performance is good, an oxidation reaction of oxygen in air and graphite product under a high temperature state can be effectively insolated, oxidation speed is delayed, and life and usage period of the graphite product with high purity can be increased.
Description
Technical field
The present invention relates to fire resisting material field, be specifically related to a kind of graphite product antioxidant.
Background technology
Graphite material is structural articles important in various machinery, and because graphite material self-lubricating, hardness are low, rub the feature such as little, and various installations have a lot of application.But graphite just starts when temperature is 500 degree and the oxygen generation oxygenizement in air, surface can oxidized fall, affect the work-ing life of machine.Therefore people design a lot of ways the antioxidant property improving graphite.
Antioxidant can form the very thin anti oxidation layer protective membrane of one deck on graphite product surface.In well-oxygenated environment within 1000 degree, graphite product antioxidant can play effective isolated air, delay graphite product oxidation rate, and can the liquid of impedance high temperature aluminum to a certain extent to effect of degrading of graphite product, improve the work-ing life of graphite product greatly.
But now antioxidant on the market usually have that antioxidant effect is bad, complicated operation, with the problem such as the sticking power of graphite substrate is bad, still affect the use of graphite material and machine mechanical.
