Description

Low abrasion and environmentally friendly tail seal grease of shield and preparation method thereof
Technical field
The present invention relates to a kind of novel shield tail sealing grease, particularly a kind of low abrasion and environmentally friendly it is used for shield Formula of shield seal grease of machine and preparation method thereof.
Background technology
Over nearly 20 years, urban track traffic and Tunnel Engineering flourish.In order to adapt to the development of urban track traffic, shield Structure method is the method that densely populated property underground engineering is mainly used, and the main equipment of construction is shield machine.Tunneled in shield machine During, because shield tail is with having relative slip in tubulature piece, and there is gap, tail sealing between section of jurisdiction outer wall and shield tail The lubrication and sealing function of grease, can effectively protect shield tail and isolation mud, prevent the people of oozing of muddy water and mud jacking, ensure shield Structure makes smooth advances.Tail seal grease of shield be by grease, heavy oil, solvent and powder filler according to a certain percentage be well mixed and Into paste.Wherein heavy oil organically combines the humidification of the water-resistance and adhesive force of grease and fiber Come, entered when using with infusion, tail seal grease of shield is firmly sticked on the shield tail wire brush of shield machine, with excellent Sealing property, can resist washing away for high hydraulic pressure and water, be effectively protected shield tail and isolation mud, prevent mud from penetrating into, it is ensured that shield The normal propulsion of structure.To make tail seal grease of shield reach estimated performance and using effect, the suitable grease of selection, fibre are studied The raw materials such as dimension, heavy oil, solvent, powder, research and design constitutes the rational proportion of each raw material of tail seal grease of shield, it is determined that formula And technique, carry out various development works.Tail seal grease of shield cost in the market is generally higher, existing tail seal grease of shield Kind it is very different, especially in terms of compressive sealed property, pumping and environmental-protecting performance be difficult really meet commercial Application Demand.This is primarily due to existing seal grease largely using artificial synthesized additive such as synthetic fibers etc., and these manually add Plus agent is also difficult to be biodegradable not only bad for optimization properties of product, and environmental pressure is caused during use.
And currently used as encapsulant natural degradable fiber more than extract from the fiber extracted to trees or cotton Fiber, relative cost is higher, and simple string does not possess lubrication, and abrasion are higher, is unfavorable for properties of product optimization. Here we first by wastes of crops such as：The string of the acquirement such as wheat straw, corn and sorghum straw, straw, bagasse is with lacking The mineral fibres that measurer has lubrication is mixed, and synthesis has the low high performance encapsulant of abrasion, has invented one kind and has more passed through Ji environmental protection, the tail seal grease of shield with good compressive sealed property and pumping.
The content of the invention
The goal of the invention of the present invention is to provide a kind of with good compressive sealed property, low abrasion, performance stabilization, lubricity By force, viscous force is strong, safety and environmental protection and the simple environmentally friendly tail seal grease of shield of preparation technology.
The technical scheme is that：A kind of low abrasion and environmentally friendly tail seal grease of shield, wherein each constituent And its mass percent is as follows：
10~15% base oil, 15~35% powder filler, 7~15% thickener, 3~10% tackifier, 1~5% are helped Dispersant, 10~30% water resistant encapsulant, 2~85% anti-static material/, preservative 0.2~2%, toner 1~5%.
Further, selected pumpability material, is mainly mixed by a small amount of natural mineral fiber and string Form.Natural minerals fiber is that the ore with fibre structure in nature is carried out into pulverization process, and surface compound treatment is obtained The material arrived.When being mixed with string, the netted structure of composite fibre can be formed, abrasion are greatly reduced.Fibrous material has one Fixed horizontal and vertical intensity, therefore with good lubrication and pumpability energy.
Further the natural mineral fiber is selected from sepiolite fibre, brucite fiber, asbestos fibre, basalt fibre In one or more.
Further the string is a kind of or many in wheat straw, corn and sorghum straw, straw, bagasse etc. Kind.
Further, a kind of the latter that the base oil mainly includes in artificial oil, mineral oil and vegetable oil is a variety of.It is described Mineral oil is including naphthenic base oils etc..The vegetable oil includes corn oil, soybean oil, peanut oil and castor oil etc..It is described to close Include DOTP, pentaerythritol ester etc. into oil.
Further, the fleut includes calcium carbonate, lime stone, talcum powder, mica powder, barium sulfate, bentonite etc.. Preferentially mica powder is used in the application.Because mica powder has good elasticity, toughness.It is insulating properties, high temperature resistant, acidproof The characteristic such as alkali, corrosion-resistant, adhesive force is strong.The thickener be selected from POLYPROPYLENE GLYCOL, hydrogenated vegetable oil, one kind of polyacrylamide or It is a variety of.The dispersion aids is selected from ketone, ether, the one or more of alcohols.Selected tackifier include C5 Petropols, C9 oil Resin, rosin and its derivative, agar etc..
The preparation method of the above-mentioned environmentally friendly tail seal grease of shield of the present invention, preparation process is as follows：
The preparation method of tail seal grease of shield is main based on blending, first by 10~15% base oils, 15~25% powder Filler and 3~10% tackifier are mixed into reactor, are heated to more than 100 DEG C, until tackifier are completely dissolved, are well mixed. And then, 1~5% dispersion aids is added in mixture, constant temperature is stirred to well mixed.Then add 7~15% thickeners, 2~8% anti-static materials are warming up to 140 DEG C, stir.Add 10~30% water resistant encapsulants, preservative 0.2~2%, The insulation of toner 1~5% continues stirring at low speed 2~3 hours.
Beneficial effect：Compared with existing seal grease, tail seal grease of shield of the invention has significantly low wear away, preferably Pumping, pumpability, adhesiveness the features such as.
