Problems solved by technology

[0004] The technical problem to be solved by the present invention: in view of the fact that the surfactants used in the current metal cleaning agent are difficult to biodegrade, and at the same time, the discharge of phosphorus-containing substances is easy to cause eutrophic pollution and environmental pollution. As a substrate, soak in hydrochloric acid, remove impurities under ultrasonic, then mix with cinnamon bark, etc., ferment with tea fungus, extract tea saponin in the fermented product and unique alcohol in cinnamon bark by isopropanol and n-hexane Phenolic substances and flavonoids in fennel seeds are used as surfactants, penetrating agents and corrosion inhibitors, then react with triethanolamine and sodium silicate under the action of sodium dioxide, and finally mix with linear alkylbenzenesulfonic acid, Thereby preparing an environment-friendly composite metal cleaning agent that is easy to biodegrade, has no pollution to the environment, and has a high cleaning effect

Abstract

The invention relates to a preparing method for an environment-friendly type composite metal cleaning agent and belongs to the technical field of metal cleaning agents. The preparing method is used for solving the problems that a surface active agent adopted for a current metal cleaning agent is hard to biodegrade, meanwhile, eutrophication pollution is likely to be caused after phosphorus containing substances are discharged, and environment pollution is caused. According to the preparing method, natural plants of tea leaves and anise seeds serve as a matrix and are immersed through hydrochloric acid, impurity removing is conducted under ultrasounds, then the tea leaves and the anise seeds are mixed with cinnamon barks and the like, fermentation is conducted through tea fungus, tea saponin in the fermented matter, specific phenolic substances in the cinnamon barks and flavonoid substances in the anise seeds are extracted through isopropyl alcohol and normal hexane to serve as a surface active agent, a penetrating agent and a corrosion inhibitor correspondingly and react with triethanolamine and sodium silicate under the effect of sodium dioxide, and finally the obtained mixture is mixed with linear alkyl benzene sulphonic acid. Thus, the environment-friendly type composite metal cleaning agent easy to biodegrade, free of pollution to the environment and good in cleaning effect is prepared.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly composite metal cleaning agent, belonging to the technical field of metal cleaning agents. Background technique [0002] Before processing and treatment of metal materials, there is usually a layer of anti-rust oil and machining oil mainly composed of mineral oil on the surface, which needs to be cleaned before subsequent processing. At present, the commonly used metal cleaning agents are solvent-based, semi-solvent-based, and water-based, among which water-based metal cleaning agents have low production costs and good environmental performance, and have been widely used. Most of the existing water-based metal cleaning agents are surface active compounds composed of alkylphenol polyoxyethylene ether (OP-10), nonylphenol polyoxyethylene ether (NP-10), and alkylbenzene sulfonate sodium (LAS). agent as the main ingredient. Since OP surfactants are difficult to biodegrade, it ha...
