Abstract
The present invention discloses a shield machine cutterhead main shaft sealing grease, wherein the raw materials comprise, by weight, 25-30 parts of base oil, 10-16 parts of a thickening agent, 45-55 parts of a filler, 3-5 parts of a lubricant, 10-15 parts of a tackifier, 2-4 parts of an antioxidant, 3-6 parts of an anti-mildew agent, and 5-8 parts of synthetic fibers, the base oil, the thickening agent, the lubricant, the antioxidant and the anti-mildew agent are poured into a mixing stirrer, mixing stirring is performed for 40 min to achieve a uniform state, the filler is poured in three batches, uniform mixing is performed, the fibers are poured, mixing stirring is performed for about 90 min, and grinding is performed 1-2 times by using a three-roller machine. According to the present invention, the shield machine cutterhead main shaft sealing grease has advantages of strong adhesion, good pumping effect, excellent sealing performance, excellent water resistance, and good adhesion with wet base plane, can be degraded by microorganisms in soil so as not to cause pollution on soil and groundwater, and belongs to the environmentally friendly product.
Description
Technical field
The present invention relates to a kind of shield engine cutter spindle seal grease.
Background technology
In recent years, China's subway cause develop rapidly, up to the present, more than 40 city, the whole nation has started the upsurge of building subway.Building of subway mainly adopts shield construction, and therefore, increasing shield excavation machine is applied in the subway construction in each city, thus needs a large amount of seal greases to do the cutter spindle seal cartridge conservation treatment of shield excavation machine.
Cutter spindle seal grease is the sealing material injected in a kind of cutter spindle seal cartridge outer gland sealing system of tunneling shield development machine in underground works shielded construction, mainly plays lubrication, sealing, waterproof, corrosion protection effect.During shield excavation machine work, the rotary grease pump linkage work of cutterhead, cutter spindle seal grease is filled in outer gland sealing system, silt mud etc. is avoided directly to contact with cutter spindle seal cartridge, thus avoid steel seal cartridge to be subject to the erosion of silt mud, play the effect in extension device parts work-ing life.
summary of the invention
The technical issues that need to address of the present invention are according to the needs of equipment protection and adapt to construction environment complicated and changeable; there is provided a kind of shield engine cutter spindle seal grease of round-the-clock full landform, the performance such as it needs to have existing good pumping, water-insoluble, sticking power, rubber seal consistency, water resistant are washed away.
For solving the problem, the present invention is achieved through the following technical solutions:
Shield engine cutter spindle seal grease is by the raw material of following weight: base oil 25-30 part, thickening material 10-16 part, stopping composition 45-55 part, lubricant 3-5 part, tackifier 10-15 part, antioxidant 2-4 part, mould inhibitor 3-6 part and synthon 5-8 part combine, its preparation method is, first at normal temperatures, by metering by base oil, thickening material, lubricant, antioxidant and mould inhibitor to drop in mixing and blending machine mix and blend 40 minutes evenly after, then drop into stopping composition in three batches to mix, finally drop into fiber, mix and blend about 90 minutes, then with three-roller grinding 1-2 time, it is strong that the present invention has adhesivity, pumping effect is good, sealing property is excellent, have excellent water-resistance, the advantage that moisture substrate adhesive power is good, and it can be degraded by the Institute of Micro-biology in soil, can not form soil and groundwater and pollute, belong to environmentally friendly product.
Preferably, shield engine cutter spindle seal grease is by the raw material of following masses part proportioning: base oil 25-30 part, thickening material 10-16 part, stopping composition 45-55 part, lubricant 3-5 part, tackifier 10-15 part, antioxidant 2-4 part, mould inhibitor 3-6 part and synthon 5-8 part combine.
