The environment-friendly type shield tail sealing grease prepared by using the method is used for sealing a shield tail of a shield tunneling machine in tunnel engineering, and has the advantages of good water pressure sealing performance, excellent pumping performance, high adhesivity, good lubrication, stable properties, no corrosion, antioxidation, wide raw material resources, environment-friendliness and simple preparation process.
Description
Technical field
The present invention relates to a kind of tail seal grease of shield of shield engine, relate in particular to formula of a kind of environmentally friendly tail seal grease of shield and preparation method thereof and application.
Background technology
At present, subway and track traffic are just entering a unprecedented flourish phase, build surface structures and daily life in order not affect oneself, the underground engineering construction method in densely populated type city mainly adopts shield construction, and the main facility of construction are shield engine.Shield engine, in the time of driving, exists one can supply a gap of shield engine activity between shield tail and own tubulature sheet, in order to prevent that outside underground water and the mud being injected into after wall from pouring in shield body, must be equipped with tail sealing device of shield between shield tail and section of jurisdiction.
Therefore, tail seal grease of shield must have good hydraulic pressure resistance stopping property, pumping and adhesivity; Although import tail seal grease of shield has the advantage in performance at present, but price is relatively expensive simultaneously, increased the cost of shielded construction, and the quality of domestic seal grease is very different, and mostly all has the problem of pumping and hermetic seal poor performance.
Summary of the invention
The object of this invention is to provide a kind ofly have that hydraulic pressure resistance stopping property is strong, pumping is excellent, adhesivity is strong, oilness is good, stable performance, corrosion-free, anti-oxidant, raw material sources are extensive, the formula of the environmentally friendly and simple environmentally friendly tail seal grease of shield of preparation technology and preparation method thereof and application.
The object of the invention is to be achieved through the following technical solutions:
Environmentally friendly tail seal grease of shield of the present invention, comprises that following component is by proportion by weight: lubricating oil 14～30%, oil product softening agent 7～22%, thickening material 3～15%, lubricating grease 3～12%, natural degradable fiber 3～8%, filler particles material 35～60%, toner 1～3%, sanitas 0.1～2%.
The preparation method of above-mentioned environmentally friendly tail seal grease of shield of the present invention, comprises step:
First, lubricating oil is heated in heating kettle behind 80 ℃ of left and right, thickening material added to heating kettle under agitation condition and keep temperature until lubricating oil and thickening material mix completely, is cooled to 30 ℃ of left and right;
Then, the mixture of cooled lubricating oil and thickening material is transferred in grease kneader, and oil product softening agent, lubricating grease and filler particles material are under agitation joined successively in grease kneader and mediated to even;
Afterwards, add natural degradable fiber, and mediate and stir 1～3h;
Finally, add toner and sanitas, and stir.
The application of above-mentioned environmentally friendly tail seal grease of shield of the present invention, is mainly used in the tail sealing of shield engine in Tunnel Engineering.
As seen from the above technical solution provided by the invention, formula of the environmentally friendly tail seal grease of shield that the embodiment of the present invention provides and preparation method thereof and application, by comprising that following component is by proportion by weight: lubricating oil 14～30%, oil product softening agent 7～22%, thickening material 3～15%, lubricating grease 3～12%, natural degradable fiber 3～8%, filler particles material 35～60%, toner 1～3%, sanitas 0.1～2%.The temperature and time of mediating by control, the environmentally friendly tail seal grease of shield of preparation, is mainly used in the tail sealing of shield engine in Tunnel Engineering.Its hydraulic pressure resistance stopping property is strong, pumping is excellent, adhesivity is strong, oilness is good, stable performance, corrosion-free, anti-oxidant, raw material sources are extensive, environmentally friendly and preparation technology is simple.The hydraulic pressure resistance stopping property of product has suitable advantage compared with same kind of products at abroad, and pumping also comes out at the top in like product at home, thereby can greatly reduce the obstruction of greasing pipe, improves the working efficiency of shield engine in Tunnel Engineering; And corrosion-free to equipment, composition is harmless, and environment is not had a negative impact, meet the requirement of environmental protection.
