Normal-temperature cleaning anti-rust agent of cylinder body of host machine of iron-casting diesel engine and preparation method thereof

Abstract

The invention relates to a normal-temperature cleaning anti-rust agent of a cylinder body of a host machine of an iron-casting diesel engine and a preparation method thereof; the anti-rust agent has aformula as follows: 2-8 percent of sodium tripolyphosphate, 2-8 percent of sodium hexametaphosphate, 2-10 percent of metasilicate pentahydrate, 1-4 percent of sodium hydrogen carbonate, 8-12 percentof QYL-23, 3-6 percent of AEO, 0.1-1.2 percent of JFC, 4-6 percent of polyethyleneglycol, 3-5 percent of sulfonated castor oil, 0.2-2 percent of nekal BX, 3-5 percent of defoamer and remaining water;the preparation method is that: running water is added in a reaction kettle, the temperature is heated to 40-50 DEG C, and then the running water is stirred, and then the sodium tripolyphosphate, thesodium hexametaphosphate, the metasilicate pentahydrate, the sodium hydrogen carbonate, the nekal BX are sequentially added and are stirred until the temperature is reduced to below 30 DEG C, and thenthe QYL-23, the AEO, the JFC, the polyethyleneglycol and the sulfonated castor oil which are metered are sequentially added, until water-solubility liquid is formed. The anti-rust agent can be used at normal temperature and energy is saved; meanwhile, the anti-rust agent has the functions of rust protection, simple process and low cost; and the method can be easily operated and controlled.

Description

technical field [0001] The invention relates to an antirust agent and a preparation method thereof, in particular to an antirust agent for normal temperature cleaning of a main cylinder body of a cast iron diesel engine and a preparation method thereof. Background technique [0002] In all kinds of industrial production, industrial cleaning technology will be applied, using cleaning equipment and cleaning agents to carry out cleaning, including ultrasonic cleaning, steam cleaning, high-pressure cleaning, ozone-ultraviolet cleaning, ion beam cleaning and plasma cleaning, etc. The process flow of the existing automatic high-pressure spray cleaning machine is: high-temperature spray cleaning → spray water washing → high-temperature spray anti-rust treatment → hot air drying → cooling to normal temperature → dipping in anti-rust oil → compressed air blowing oil → unloading and packaging. [0003] Due to the complex structure of the cast iron diesel engine main engine cylinder, t...

AI Technical Summary

Problems solved by technology

At present, the cleaning of the main cylinder of cast iron diesel engine adopts automatic high-pressure jet cleaning machine and the cleaning agent provided by BASF of Germany. After cleaning, an anti-rust treatment process must be set up separately, and the price is expensive
