TECHNICAL FIELD
[0001] The present application relates to the field of brake fluid production equipment, in particular to a high wear-resistant brake fluid and a reaction device thereof. BACKGROUND
[0002] Brake fluid, also known as brake oil, is a liquid medium for transmitting pressure in the hydraulic brake system of an automobile. In the production process, the oxidation resistance, corrosion resistance and thermal stability of the brake fluid are usually optimized to achieve high wear resistance. In addition, the synthesis of the brake fluid needs to be carried out in an inert environment, and after production, the brake fluid needs to be filtered at the nanometer level and then sealed by vacuum filling. Chinese Patent Application No. 201710897222.1 discloses a DOT6 borate ester type brake fluid. The brake fluid comprises the following components by mass percentage: polyethylene glycol ether: 3-16%; triethylene glycol methyl ether borate: 82-95%; 6-methyl-2-mercaptobenzothiazole: 0.05-0.15%; methylbenzotriazole: 0.05-0.15%; N-methyl monoethanolamine: 0.5-1.0%; antioxidant 1010: 0.05-0.1%; 2-ethylhexyl acrylate: 0.04-0.2%; 4,4'-butylene bis(6-t-butyl-m-cresol): 0.01-0.05%; nipagin ester: 0.01-0.05%; dodecenyl succinic acid (T746): 0.01-0.05%; alkalinity regulator: 0.5-1.0%. The use of triethylene glycol methyl ether borate obtained by the preferred esterification process can effectively solve the higher dry and wet boiling point requirements of DOT6, and also has excellent low temperature driving performance and more sensitive braking. The technical solution proposed in the above-mentioned application improves the formula of the brake fluid to achieve the desired effect. However, the equipment used in the preparation process and storage have not been improved. For example, the inert environment during production, how to filter and how to store and transport are critical to product quality. SUMMARY
[0003] Therefore, in view of the above problems, the present application provides a high wear-resistant brake fluid and a reaction device thereof, which solves the technical problems of insufficient wear resistance of the existing brake fluid and imperfect filtering process during production, which leads to the presence of particles invisible to the naked eye in the brake fluid, thereby easily causing the ABS pump to be blocked during use.
[0004] To achieve the above object, the application adopts the following technical scheme: a high wear resistance brake fluid comprises the following raw materials in parts by weight: triethylene glycol monomethyl ether borate 50-70 parts, triethylene glycol monomethyl ether 20-40 parts, tetraethylene glycol methyl ether 5-10 parts, triethylene glycol ethyl ether 0-20 parts, benzotriazole 0.05-0.1 parts, methyl benzotriazole 0.05-0.1 parts, bisphenol A 0.1-1 parts, base value reinforcing agent 0.1-1 parts, and improver 0.1-10 parts, wherein the total weight of the triethylene glycol monomethyl ether borate, the triethylene glycol monomethyl ether, the tetraethylene glycol methyl ether and the triethylene glycol ethyl ether is 100 parts.

[0010] Further, the center of the grinding pressure plate is bent towards the first grinding disc, a first pushing part is arranged at one end of the grinding pressure plate close to the ring-shaped sleeve, a second pushing part is arranged on the driving rotation shaft, and the first and second pushing parts cooperate with each other.
[0011] Furthermore, the second pushing part is a pushing protrusion surrounding the active drive shaft.

[0016] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:
[0017] 1. The brake fluid formulation of this invention uses triethylene glycol monomethyl ether borate ester, a borate ester compound, as the main component. As a base solvent, it provides excellent low-temperature fluidity and anti-vapor lock properties, and is not easily vaporized at high temperatures, ensuring stable brake pressure transmission while enhancing overall solubility and stability. Triethylene glycol monomethyl ether and tetraethylene glycol methyl ether serve as auxiliary solvents, adjusting viscosity and fluidity while aiding in the dissolution of other additives. Ether solvents in a polyethylene glycol system improve low-temperature performance, preventing brake fluid from solidifying in cold environments. Benzotriazole and methylbenzotriazole act as buffers, protecting metal components from corrosion. Bisphenol A is used as a stabilizer, improving thermal stability and chemical inertness, extending brake fluid life. The combination of base-reinforcing agents and modifiers enhances acid-base balance and overall performance. This formulation, through optimized ether-boronate ratios and additive combinations, strengthens the brake fluid's rust prevention, corrosion resistance, and high-temperature adaptability, meeting the DOT4 standard requirements for thermal stability and safety redundancy.
[0018] 2. The reaction equipment proposed in this invention is mainly used for grinding and sieving brake fluid. During the brake fluid manufacturing process, due to the interaction between raw materials and the possibility that solutes may not be completely dissolved in the solvent, potential particulate matter may remain in the solution. This particulate matter can cause ABS pump blockage during later use. Therefore, this reaction equipment uses a grinding mechanism to finely grind the brake fluid, followed by filtration and purification through a sieving mechanism, ensuring the quality of the finished product. Specifically, the grinding mechanism uses a first grinding disc and a second grinding disc to achieve intermittent grinding. As the second grinding disc rotates, the solution flows from top to bottom into the gap between the first and second grinding discs for initial grinding. Further grinding is then carried out by the grinding disc set on the first grinding disc. The grinding plate assembly performs intermittent fine grinding of the solution. The reason for using intermittent grinding is that: firstly, the brake fluid itself uses fine raw materials in the production process, and the raw material ratio is relatively perfect and reasonable; secondly, it would be too wasteful to perform full fine grinding on raw materials that have already been finely processed. Therefore, intermittent grinding is adopted. The second pusher on the active drive shaft pushes the first pusher on the grinding plate. Since the structural design of the grinding plate is already biased towards the first grinding disk, when the first pusher on the grinding plate is pushed by the second pusher on the active drive shaft, its bending range is greater. That is, the grinding plate continues to bend downward until it abuts against the second grinding disk through the first groove and generates a downward pressure on the second grinding disk, thereby improving the fineness of grinding.
[0019] 3. In this invention, a grinding groove is provided on the side of the second grinding disc near the first grinding disc. The grinding groove is adapted to the grinding pressure plate and adopts a stepped structure design. The upward trend of the steps is opposite to the rotation direction of the active drive shaft, which avoids rotational interference with the grinding pressure plate. Through the design of the grinding groove, its stepped upward inclined surface, together with the grinding pressure plate, can provide greater pressure between the two, thereby improving the grinding accuracy.
[0020] 4. In this invention, after the solution is ground by the grinding mechanism, it continues to seep downwards to the screening mechanism. The screening mechanism adopts a working method in which the first screen and the second screen work together. The screening density of the two screens is different, with the screening density of the second screen being less than that of the first screen. However, the second screen is set below the first screen and has a larger cross-sectional area than the first screen. By having the second screen continuously press against the first screen below it and rub against it back and forth, the two screens are stacked and move in a staggered manner, which can improve the screening density. On the other hand, the back-and-forth friction between the surfaces of the first and second screens during the working process can prevent the two screens from becoming blocked. During the working process, the two screens can mutually unclog each other. Attached Figure Description
