Cleaning and antirusting agent for steel shots stuck with carbon black and preparation method thereof

Abstract

The invention discloses a cleaning and antirusting agent for steel shots stuck with carbon black, which has strong detergency and can prevent rusting. The used materials and weight percent are as follows: 28 to 32 percent of industrial sulphuric acid, 4 to 8 percent of industrial hydrochloric acid, 1 to 3 percent of phosphoric acid, 1 to 2 percent of citric acid, 1 to 2 percent of JFC, 2 to 4 percent of ethylene glycol monobutyl ether, 1 to 2 percent of QYL-290, 1 to 2 percent of NP-9 and the balance of water. A preparation method is carried out according to the following steps: in a reinforced PPC plastic reaction kettle, a calculated amount of water is first added, a calculated amount of sulphuric acid is then slowly added, the temperature is naturally decreased to the normal temperature, a stirrer is started, the rotation speed is 40 to 60 rotations per minute, a calculated amount of hydrochloric acid, a calculated amount of phosphoric acid, a calculated amount of citric acid, a calculated amount of JFC, a calculated amount of ethylene glycol monobutyl ether, a calculated amount of QYL-290 and a calculated amount of NP-9 are then sequentially added, and stirring is continuously carried out for 30 to 60 minutes.

Description

technical field [0001] The invention relates to an industrial dirt cleaning agent and a preparation method thereof, in particular to a cleaning and antirust agent adhering to carbon black steel grit with strong detergency and antirust and a preparation method thereof. Background technique [0002] In industrial production, various mechanical equipment, metal raw materials and products or semi-finished products, etc., will undergo physical, chemical or biological actions during the contact process with the atmospheric environment, production materials, media and mechanical oil, and will remain and accumulate on the surface And generate all kinds of dirt. Various effective technical measures (physical, chemical or biological process methods) must be taken to remove the dirt, otherwise not only the production cannot run normally, the product quality cannot be guaranteed, but also the consumption of raw materials and energy will increase, and even It will cause various producti...

Problems solved by technology

However, the existing cleaning agents cannot thoroughly clean the carbon black on the surface of the steel grit and cannot guarantee the anti-rust of the steel grit surface. This problem has always plagued the rhythmic production of the enterprise's process
