Description
Technical Field
The invention relates to the field of metal cutting fluid settling agents, in particular to a settling agent for semisynthetic cutting fluid, a preparation method and application thereof and semisynthetic cutting fluid.
Background
The metal working fluid is an important material in the metal working process, can play roles of lubrication, cooling, cleaning, rust prevention and the like, and is divided into three types of total synthetic cutting fluid, emulsion fluid and semi-synthetic cutting fluid. The total synthetic cutting fluid has a problem of insufficient lubricity, poor rust resistance, and the like, although it is excellent in cooling performance. The emulsion has the problems of short service life of working solution, low visibility in processing, difficult waste liquid treatment and the like. The lubricating and cooling performance of the semisynthetic cutting fluid is between that of the emulsion and the fully synthetic cutting fluid, so that the defects of the emulsion and the fully synthetic cutting fluid are overcome, and the universality is strong.
When the semisynthetic cutting fluid is used in a grinding process or cutting scraps are very fine, the problem that metal scraps are difficult to settle exists, the scraps are fine and cannot be filtered by a filter screen, and suspended in the semisynthetic cutting fluid can have influence on machining precision and even cause workpiece scratches, and meanwhile, the semisynthetic cutting fluid is not beneficial to recycling of metal materials, and particularly, certain materials with higher prices such as rubidium-iron-boron are not beneficial. The existing method has the problems that the penetrating agent is added, the adding amount is about 2-5% of the mass of the stock solution, the sedimentation effect is achieved after the surface tension is reduced, but the penetrating agent contains more hydrophilic groups, the foam is extremely large during use, the foam is not controlled during use of the cutting fluid, the lubricity of the working fluid is greatly influenced by the foam, the working environment is polluted by overflow of an oil tank, and the like. In addition, a method of adding a cationic sedimentation agent is adopted, but cations react with an anionic additive which is almost unavoidable in the cutting fluid, so that the water-oil balance is damaged to cause demulsification, and the cations react with components of the rust inhibitor and cannot be adsorbed on the metal surface to play a role in rust protection.
Along with the higher and higher metal machining precision, fragments become finer and finer, semisynthetic cutting fluid can well provide lubrication protection, but sedimentation problems are outstanding, no sedimentation agent for semisynthetic cutting fluid is available on the market at present, various cutting fluid production enterprises are searching for solutions, and market application prospects are wide.
