Abstract

PURPOSE:To privide the titled composition consisting of (1) water, (2) a W/O type polymer emulsion which may contain an extreme-pressure additive, a lubricant, a mineral, animal or vegetable oil and an emulsifier and (3) a mineral substance, and exhibiting an excellent antifriction property. CONSTITUTION:The composition is prepared by blending (1) 100pts.wt. water, (2) 0.2-10pts.wt. W/O type polymer emulsion which may contain an extreme-pressure additive, a lubricant, a mineral, animal or vegetable oil and an emulsifier and (3) 2-20pts.wt. mineral substance (e.g. bentonite, clay or graphite). To obtain an antifriction material, a vinyl monomer is emulsified and dispersed in a mineral oil by use of an emulsifier, effecting emulsion polymerization in the presence of a catalyst and adding to the resultant polymer emulsion an extreme- pressure additive, a lubricant, a mineral, animal or vegetable oil which controls polymer concentration and increases lubricity, an emulsifier to enhance water dispersibility, etc.

The shield propulsion method is a construction method for constructing underground tunnels for power lines, telegraph and telephone lines, water and sewage lines, etc. by pushing concrete or cast iron pipes into the ground using hydraulic jacks, and since it does not involve excavation of the ground surface, it reduces traffic and It is widely used because it has relatively little impact on commercial activities.

In this construction method, the pipes are pushed into the ground, so the driving force required for pushing increases depending on the number (distance) of the pipes pushed, so the reaction wall with the pipes and propulsion jacks There is a problem in that the propulsion distance is limited due to strength.

The longer the distance to be propelled, the better the construction efficiency, so in order to extend the distance, we have also adopted a method of increasing the propulsive force by installing several intermediate jacks between the propulsion tubes depending on the distance of propulsion. has been done.

Although this method can be expected to be relatively effective in reducing the propulsion force, it is complicated to prepare the lubricant because several types of materials are mixed. In addition, since the lubricant has a high viscosity, a dissolving machine dedicated to preparing the lubricant is required, and since glues such as CMC and sodium polyacrylate are powdered, they are completely dissolved. It takes a long time to prepare the lubricant, and if the dissolution state is insufficient, the anti-friction effect is significantly reduced. The development of something was awaited.
