Problems solved by technology

[0003] At present, there are few types of cleaning agents specially developed for steel mesh cleaning on the market, and the number of related patents is lacking, and the content is not very detailed. For example, Chinese patent (CN103882461A) discloses the preparation of a cleaning agent for steel mesh, which belongs to water-based section steel. The net cleaning agent mainly achieves the effect of cleaning the steel net through the synergistic effect of surfactants and additives in aqueous solution, but has the following defects: first, the content of surfactant is too high, reaching 20% ​​of the system mass percentage, The cost of the cleaning agent is too high; secondly, the surfactants in the formula belong to the conventional surfactants on the market, and their performance is average. After being made into an aqueous solution, they can only remove some non-stubborn grease, etc. For stubborn stains such as glue, paint, etc. The effect is poor
But the defect is that there is no specific cleaning method proposed, and it is the stock solution cleaning, the cost is too high

Abstract

The invention relates to the technical field of cleaning agents, in particular to a novel steel mesh cleaning agent and a preparation method thereof. According to the raw material formula, the novel steel mesh cleaning agent comprises components including, by weight, 30-50 parts of dipropylene glycol mono butyl ether, 40-50 parts of dipropylene glycol methyl ether, 2-5 parts of tetrahydrofurfurylalcohol, 1-2 parts of a corrosion inhibitor, 1-2 part of an emulsifier, 1-2 parts of a chelating agent and 2-4 parts of an activator. The novel steel mesh cleaning agent is a green environmental protection cleaning agent, does not contain a fluorocarbon solvent and a halogenated hydrocarbon solvent, cannot hurt the health of the human body, is convenient to use, environment-friendly, safe, non-toxic and economical, and is simple in using method. After a stock solution is diluted to five times of the mass, ultrasonic cleaning or spraying cleaning can be carried out. Dirt on the surface of a steel mesh can be significantly removed, and the steel mesh cleaned by the cleaning agent can be directly reused after being rinsed with water and dried with air.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a novel steel mesh cleaning agent and a preparation method thereof. Background technique [0002] Most SMT processing manufacturers now use electric stencil cleaning machines, usually spray or ultrasonic cleaning, and use solvent-based cleaning agents such as alcohol or IPA. These solvents are like panacea and are used in most cleaning fields, but they are not the best. s Choice. First of all, solvent-based cleaning agents evaporate quickly and are easily spread into the air. They have a pungent odor, pollute the workshop environment, and pose a threat to the health of workers after being absorbed by the human body. If the ventilation is not smooth, there will be a danger of explosion after reaching a certain concentration. Secondly, because the solvent-based cleaning agent volatilizes quickly, the cleaning agent needs to be added frequently, and the consumption is large...
