Abstract
The invention relates to a high-temperature resistance matter in the chemical field, in particular to a compound high-performance and high-temperature seizure resistance agent, which comprises ingredients in percent by weight: 35 percent of solid materials and 65 percent of liquid materials, wherein the solid materials comprise 32 to 34 percent of graphite with the fineness of 5000 meshes, 37 to 39 percent of graphite with the fineness of 10000 meshes and 28 to 30 percent of graphite with the fineness of 1250 meshes; and the liquid materials comprise 70 to 75 percent of polyisobutene (PB1300) and 25 to 30 percent of simethicone. The compound high-performance and high-temperature seizure resistance agent can prevent the occlusion, the rusting and the corrosion of screw bolts and fasteners in high-temperature static conditions and can also perfectly lubricate dynamic parts; the screw bolts can be freely dismounted during overhauling, the time and the labor can be saved, and the compound high-performance and high-temperature seizure resistance agent can also play better protection effect on dynamic equipment parts.
Description
Technical field
The present invention relates to high temperature resistant material in the chemical field, is a kind of compound high-performance high temperature anti-bite mixture specifically.Described anti-bite mixture is used to prevent metallic element fastening position interlock under the high temperature, improves lubricants performance.
Background technology
At present, industries such as chemical industry, petrochemical industry, chemical fertilizer, metallurgy, thermoelectricity, steamer, mine, automobile making at home, in the installation of high temperature heavy loading equipment, the inspection travel, the lubricated main common lubricating grease such as calcium grease, lithium saponify, Vaseline that use such as the anti-interlock of bolt, valve rod, screw rod, chain, gear, wirerope etc., these lubricated products can also play lubrication under normal temperature condition, but will volatilize and coking loses due lubrication as high temperature, and cause static bolt fasteners interlock; Wearing and tearing such as dynamic gear, wirerope, chain.
The bolt fasteners of interlock can't be dismantled in maintenance and can only slice off, not only waste time and energy, also can strengthen workload, What is more at some special occasions, get angry and have certain security risk, but also can shorten work-ing life of equipment unit such as dynamic gear, wirerope, chain, cause the waste of resource.
Summary of the invention
At the defective that exists in the prior art, the object of the present invention is to provide a kind of compound high-performance high temperature anti-bite mixture, it can prevent the dead and corrosion of interlock, rust of bolt fasteners under the high temperature static condition; Can well lubricate dynamic component again, when maintenance Bolt dismantling freely, time saving and energy saving; Also can play the better protection effect to dynamic equipment component.
For reaching above purpose, the technical scheme that the present invention takes is:
A kind of compound high-performance high temperature anti-bite mixture is characterized in that: comprise solid material 35%, liquid material 65% by weight ratio, wherein:
In the described solid material, 32～34% is fineness 5000 purpose graphite, and 37～39% is fineness 10000 purpose graphite, and 28～30% is fineness 1250 purpose boron nitride;
In the described liquid material, 70～75% is polyisobutene, and 25～30% is dimethyl silicone oil.
On the basis of technique scheme, in the described solid material, 33% is fineness 5000 purpose graphite, and 38% is fineness 10000 purpose graphite, and 29% is fineness 1250 purpose boron nitride;
In the described liquid material, 75% is polyisobutene, and 25% is dimethyl silicone oil.
Compound high-performance high temperature anti-bite mixture of the present invention, it can prevent the dead and corrosion of interlock, rust of bolt fasteners under the high temperature static condition; Can well lubricate dynamic component again, when maintenance Bolt dismantling freely, time saving and energy saving; Also can play the better protection effect to dynamic equipment component.
Embodiment
High temperature service holding bolt agglomerating reason is: during the high temperature service operation; the screw rod volumetric expansion of at first being heated; but the thermal velocity that is subjected to of nut is lower than screw rod; the difference that thermal expansion amount so just occurred---the screw expansion amount is greater than the nut swell increment; this has just caused the combination of screw rod and nut tightr; but this do not have combining closely of protecting insulating layer can not prevent the reaction of oxygen in screw thread and the air; and this reaction is at high temperature rapider; the metal oxide that generates behind the high temperature has been filled the whole gaps of screw thread; make screw rod become as a whole with nut, this will cause the increasing of Bolt dismantling moment of torsion even can't dismantle.Address this problem and to prevent fully contacting and the formation of oxide on surface of screw rod and nut exactly.
Compound high-performance high temperature anti-bite mixture of the present invention comprises solid material 35%, liquid material 65% by weight ratio, wherein:
In the described solid material, 32～34% is fineness 5000 purpose graphite, and 37～39% is fineness 10000 purpose graphite, and 28～30% is fineness 1250 purpose boron nitride;
In the described liquid material, 70～75% is polyisobutene (PB1300), and 25～30% is dimethyl silicone oil.
On the basis of technique scheme, in the described solid material, 33% is fineness 5000 purpose graphite, and 38% is fineness 10000 purpose graphite, and 29% is fineness 1250 purpose boron nitride;
In the described liquid material, 75% is polyisobutene, and 25% is dimethyl silicone oil.
Below be specific embodiment:
Get 5000 order graphite 330g, 10000 order graphite 380g, 1250 order boron nitride 290g mix that to form the solid material standby.
Other gets polyisobutene (PB1300) 750g, and viscosity is that 1000 dimethyl silicone oil 250g stirs that to form the liquid material standby.
Get the solid material 350g that mixes and pour in the 650g liquid material and mix, agitation grinding promptly gets this product---compound high-performance high temperature anti-bite mixture.Product of the present invention is the thickness paste.After tested, obtain following experimental data.
Bite-resistant principle of the present invention: the selected material of high-performance anti-bite mixture all has higher stability at elevated temperature, boron nitride is the highest to be stabilized in 3000 ℃ (are boron nitride still keeps stable) under 3000 ℃, graphite is the high-performance solid lubricant, fusing point is 3300 ℃, chemical property is highly stable, through the graphite of super-fine processing, the heatproof lubricant effect is more obvious.The heavy-gravity polyisobutene evenly adheres to thread surface with powdered material and forms resistant to elevated temperatures sealing sealing coat, and the long-term double thread of this sealing coat plays a protective role, and has prevented the formation of oxidation on metal surface thing, like this will be lighter during Bolt dismantling.
The present invention takes technique scheme, has following beneficial effect:
1, the present invention is mainly used in the metallic element under various bolts, securing member, metal bond face surface and the high temperature heavy load conditions, can prevent the dead and corrosion of interlock, sintering, wearing and tearing, rust of metal parts fastening position under the hot conditions, effectively prolong the service life of the parts such as heavy load chain, wirerope, gear, operation is got up more steady, improves the service life of dynamic device;
2, can avoid artificial sawing, the heavy manual labor of acetylene cutting and numerous and diverse technical finesse process, make it when maintenance, to dismantle freely, time saving and energy saving, thus accomplish safety inspection, the shortening time, have significant Social benefit and economic benefit.
