Abstract
The present invention relates to a kind of environment-friendly type tail seal grease of shield and preparation method thereof.The tail seal grease of shield is made up of following component by mass percentage：Base oil 10 28%, lubricating oil 5 15%, fiber 5 15%, powder 35 55%, thickener 5 14%, solvent 5 12%, antioxidant 0.5 5%.The environment-friendly type tail seal grease of shield good seal performance of the present invention, stable performance, does not have corrosivity to shield tail material, pumpable and nontoxic, odorlessness, environment is not polluted.
Description
Technical field
The invention belongs to chemical building material field, and it is close to relate in particular to a kind of shield tail of the environment-friendly type for shield excavation machine
Oil sealing fat and preparation method thereof.
Background technology
In order to adapt to the development of urban construction, underground engineering is increasing, and wherein shield-tunneling construction is urban track traffic tunnel
The main method of road construction.In shield machine tunneling process, because gap be present between shield shell-and-tube piece outer wall, in order to prevent shield shell
External water and silt particle etc. enter in shield, it is necessary to carry out encapsulation process to shield tail and section of jurisdiction gap.Seal shield tail brush and section of jurisdiction it
Between exist friction, frictional force is excessive to be easily damaged shield tail device, it is necessary to fill seal grease between tail sealing brush, with reduce
Frictional force between section of jurisdiction and shield tail brush.Tail seal grease of shield is one of primary sealing material between shield tail and section of jurisdiction, in shield
Played an important role in structure construction.Tail seal grease of shield should have sealing and lubrication, can effectively protect shield tail, completely cut off
Underground water and mud, ensure that shield makes smooth advances.Meanwhile also have the function that to prevent shield from corroding and reducing abrasion.Shield tail is close
The quality of envelope depends on the performance of tail seal grease of shield, and it directly affects the quality and safety of construction.
Research in terms of the formulation optimization and performance characterization of tail seal grease of shield is seldom.Market at home, performance are excellent
Different tail seal grease of shield is less, and especially its pumping is far below same kind of products at abroad.Tail seal grease of shield original is shield pick
Enter machine provision in set, if succeeded in developing, can not only break away from the situation for relying on import, and engineering cost can be saved.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of environment-friendly type, stable performance, the preferable shield tail of sealing property
Seal grease.
In order to solve the above technical problems, the technical solution adopted by the present invention is：The tail seal grease of shield presses quality percentage
Than being made up of following component：It is base oil 10-28%, lubricating oil 5-15%, fiber 5-15%, powder 35-55%, thickener 5-14%, molten
Agent 5-12%, antioxidant 0.5-5%.
The base oil of the tail seal grease of shield of the present invention is 32# mechanical-hydraulics oil, 46# mechanical-hydraulics oil, 68# mechanical-hydraulics

A variety of or its mixture.
One or more of the thickener of the tail seal grease of shield of the present invention for polyisobutene, in polypropylene copolymer or its
Mixture.
The powder of the tail seal grease of shield of the present invention is one or more in calcium carbonate, talcum powder and kaolin or it is mixed
Compound.
The fiber of the tail seal grease of shield of the present invention is degradable wood fibre.
The solvent of the tail seal grease of shield of the present invention is aliphatic lipid solvent.
One or more of the antioxidant of the tail seal grease of shield of the present invention for phenolic compound, in sulfide or it is mixed
Compound.
The present invention also provides a kind of method for preparing above-mentioned tail seal grease of shield, and methods described is included base oil, lubrication
Oil, thickener, solvent, antioxidant are mixed according to above-mentioned mass percent and mediated uniformly, then add powder, and stirring is equal
It is even, fiber is eventually adding, continues constant temperature stirring 1-2 hours.
Beneficial effect：The environment-friendly type tail seal grease of shield good seal performance of the present invention, stable performance, does not have to shield tail material
Corrosivity, pumpable and nontoxic, odorlessness, environment is not polluted.
