The inventor notices that due to the existence of the long molecular chain in the molecule, the molecular chain of the polymer has certain mobility so as to play a role in lubrication, and can be applied to the preparation of cutting fluid; in addition, the polymer has certain absorption capacity on vibration energy, and can convert the vibration energy into heat energy and dissipate the heat energy, so that the polymer also has the potential of being applied as a noise reduction material. Since the cutting fluid has good thermal conductivity and the actual working temperature is lower than the glass transition temperature of the polymer, the polymer tends to show rigidity at the temperature, and the movement of the molecular chain of the polymer is limited at the moment, and the absorption capacity of the vibration energy is low, so that under the special working condition, the purpose of simultaneously keeping the lubricity and the noise reduction capacity of the polymer is very difficult.
In order to solve this technical problem, the inventors prepared an aqueous polyurethane whose molecular chain segment was composed of low glass transition segment and polar polyurethane segment alternately; as a block polymer, the waterborne polyurethane prepared by the invention has good low-temperature workability, and the glass transition of the waterborne polyurethane can occur in a wider temperature range. In the preparation process of the waterborne polyurethane, the inventor uses step-by-step polymerization, polyethylene glycol monobutyl ether provides an ether structure, 2-dimethylolpropionic acid and L-tyrosine provide a reactive group carboxyl, and polyol reacts with isocyanate to form the structure of the polyurethane. The L-tyrosine builds a three-dimensional structure of the waterborne polyurethane, and the L-tyrosine is polymerized with 2, 2-dimethylolpropionic acid to realize the extension of a molecular chain and is used as a cross-linking point between molecular chains to improve the uniformity of the waterborne polyurethane.
In the synthesis process, a hydrophobic fatty acid side chain is introduced into a molecular chain of the L-tyrosine, and hydrophobic interaction and hydrophobic association are generated on a main chain of the waterborne polyurethane, so that the hydrodynamic volume of the polymer is increased; as the hydrodynamic volume and the intrinsic viscosity are in positive correlation, the intrinsic viscosity is correspondingly increased, so that the waterborne polyurethane can keep better vibration energy/heat energy conversion capability at low temperature. L-tyrosine is taken as a cross-linking point between molecular chains to increase polar polyurethane segments, so that the entanglement degree of the molecular chain segments of the waterborne polyurethane is increased, the crystals formed by rigid chain segments are reduced, and the cohesive energy and hydrogen bonds of molecules are reduced; the reduction of hydrogen bonds is beneficial to reducing the restriction on the movement of the molecular chain, and under the condition, the macromolecular chain segment can convert more vibration energy into heat energy through relaxation motion.
After the waterborne polyurethane prepared by the invention is applied to the cutting fluid, the waterborne polyurethane can absorb vibration energy of noise and convert the vibration energy into heat energy, the heat energy is taken away by the cutting fluid with good heat conductivity, and the technical purpose of reducing processing noise can be achieved through the energy conversion.

Example 2 | 62 | 58 |
Example 3 | 56 | 53 |
Comparative example 1 | 73 | 69 |
It can be observed by testing the noise generated during the machining process that the decibel of the noise generated during the machining process is reduced after the noise reduction cutting fluid is used, wherein the best noise reduction effect is achieved in the embodiment 3. This phenomenon may be caused by the fact that in the noise reduction cutting fluid used in example 3, L-tyrosine increased the number of polar polyurethane segments as a cross-linking point between molecular chains, which increased the degree of entanglement of the molecular segments of the aqueous polyurethane and decreased the formation of crystals of the rigid segment, and consequently, the intramolecular cohesive energy and hydrogen bonding were decreased; the reduction of hydrogen bonds is beneficial to reducing the restriction on the movement of the molecular chain, and under the condition, the macromolecular chain segment can convert more vibration energy into heat energy through relaxation motion.
Test example 2

The surface tension test used a ring method, the ring being made of platinum wire and having a thickness of 0.4mm and a circumference of 60mm, the ring being horizontally suspended from a wire frame on a metal rod connected to a tensiometer. The test environment temperature is 25 ℃ and the relative humidity is 50%. The results of the viscosity and surface tension tests of the cutting fluids are shown in table 2.

Comparative example 1 | 1.18 | 38 |
The permeability and heat dissipation of the cutting fluid are affected by viscosity and surface tension; therefore, viscosity and surface tension are important factors affecting the cooling and lubricating performance of the cutting fluid. As can be seen from the test results in Table 2, example 3 has the lowest viscosity and surface tension, and the liquid with low surface tension has a small contact angle on the solid surface and is easy to diffuse and permeate into the contact gap between the cutter and the workpiece; example 3 had a viscosity of 1.02 mPas, good fluidity and good lubricating and cooling effects.
