Description
Technical Field
The invention belongs to the technical field of rust preventive oil, and relates to a high-flash-point low-residue cleaning-free rust preventive oil for rust prevention of VVT parts.
Background
The quality of rust-proof oil performance of the current commercial process is not satisfactory, and some problems need to be solved. Firstly, the volatilization time of the oil agent is longer (more than 48 h), the residual quantity of the surface of the workpiece is large (the residual quantity of the oil agent is more than or equal to 5%), secondly, the flash point of the oil agent is too low (less than or equal to 60 ℃), and thirdly, the wettability and spreadability of the oil agent are poor (the surface tension of liquid is more than or equal to 30 mN/m,25 ℃). Therefore, the popularization and the application of the product in the market of VVT metal parts of the automobile engine are limited. Variable Valve Timing (VVT) is a technique used in automotive piston engines. The VVT technology can adjust the overlapping time and timing (part or all of the time) of the engine intake and exhaust system, reduce fuel consumption and improve efficiency. The variable valve timing system OCV VCT consists of an electromagnetic valve (OCV) and a variable camshaft phase regulator (VCT), and the air input can be changed along with the change of the engine rotating speed by regulating the engine cam phase, so that the optimal combustion efficiency is achieved, and the fuel economy is improved.
The invention CN116769529A discloses quick-drying rust-preventive oil and a preparation method thereof, wherein the quick-drying rust-preventive oil comprises the following components in parts by weight: 70-90 parts of mineral oil, 5-10 parts of rust inhibitor, 1-3 parts of corrosion inhibitor and 0.5-1 part of explosion inhibitor, wherein the mineral oil is formed by compounding 6# white electric oil and hydraulic oil, and the mass ratio of the 6# white electric oil to the hydraulic oil is 10:1-12:1; the preparation method of the quick-drying rust-preventive oil comprises the following steps of: adding the No. 6 white electric oil and the hydraulic oil into a container according to a proportion, and fully stirring; sequentially adding an antirust agent, a corrosion inhibitor and an explosion-proof agent into the container, and stirring until the container is uniform and transparent. The quick-drying rust-proof oil has the characteristics of excellent sweat stain replacement, water stain replacement, rust prevention, difficult emulsification of oil products, good oil-water separation, strong salt fog resistance and the like, and is suitable for short-term rust prevention treatment of steel, cast iron and powder metallurgy parts for 3-6 months.
The invention CN116253890A discloses a surface active rust inhibitor, a preparation method and application thereof, which belong to the technical field of rust prevention, wherein the preparation method of the surface active rust inhibitor comprises the following steps: carrying out graft copolymerization reaction on polyfluorosioxane and alkylphenol ethoxylates under the action of an initiator, a polarity regulator and a solvent to obtain the surface active antirust agent; the polyfluoro siloxane is one or more of trifluoro propyl methyl cyclotrisiloxane, perfluoro decyl trimethoxy silane and perfluoro octyl trimethoxy silane; the polyoxyethylene ether is nonylphenol polyoxyethylene ether and/or octylphenol polyoxyethylene ether. The surface active rust inhibitor provided by the invention can effectively reduce the surface tension, improve the extensibility and adhesive force of the rust inhibitor on the metal surface, and can improve the weather resistance and water resistance of the film when preparing the hard film rust inhibitor so as to improve the rust inhibition.
