Low-foam middle-cloud-point environment-friendly water base metal cleaner composition and preparing method thereof

Abstract

The invention provides a low-foam middle-cloud-point environment-friendly water base metal cleaner composition and a preparing method thereof, and belongs to the field of metal cleaners. The low-foam middle-cloud-point environment-friendly water base metal cleaner composition is composed of low-foam low-cloud-point nonionic surface active agents, low-foam anion surface active agents, triethanolamine oleic soap, triethanolamine, styrene acrylic three azole nitrogen, ethylene diamine tetraacetic acid, sodium carbonate, polyether, organosilicone, sodium hydroxide and deionized water, wherein solid-phase raw material and liquid-phase raw material are sequentially added to a reaction container according to a formulation and metering, the organosilicone and the deionized water are finally added to the reaction container, stirring is conducted for 10min to 20min under the condition of indoor temperature, and clear products with a pH value ranging from 9 to 10 are obtained. The triethanolamine oleic soap is a cloud point improving agent, good water solubility is achieved after the triethanolamine oleic soap and the triethanolamine are re-compounded according to the ratio, solubilizing ability of the low-foam low-cloud-point nonionic surface active agents is enhanced, therefore the temperature of the solution cloud point of the cleaner is improved to 45 DEG C, cleaning efficiency of the cleaner is improved, and the low-foam middle-cloud-point environment-friendly water base metal cleaner particularly suitable for high-pressure spraying cleaning is obtained.

Description

technical field [0001] The invention relates to a low-foaming, medium-cloud point, environment-friendly water-based metal cleaning agent composition and a preparation method thereof, belonging to the field of metal cleaning agents. Background technique [0002] At present, there are many kinds of ordinary water-based metal cleaning agents on the market, which basically belong to high-foaming cleaning agents for soaking and spray cleaning. During spray cleaning, too much foam and too long defoaming time will not only hinder the cleaning of dirt on the metal surface, but also easily produce residues of cleaning agents, which will ultimately affect the cleaning effect. On the other hand, the overflow of high foam will also affect the cleaning operation. Therefore, the market has put forward higher and higher requirements for the comprehensive performance and service conditions of cleaning agents. Improving the cleaning rate of metal can be achieved by changing the cleaning co...

Problems solved by technology

Nonionic surfactants have low foaming properties, but their use is limited due to their low cloud point and poor water solubility; and the amount of defoamers is limited due to the impact of defoaming mechanisms and economic costs, so how to improve these two factors is to achieve The key to low-foaming properties and affordability

In addition, appropriately increasing the cleaning temperature can also improve the cleaning rate of metals, but the cloud point temperature of the new non-ionic low-foaming surfactants is generally low. At room temperature, its aqueous solution becomes turbid, and the surfactant precipitates out, losing its cleaning effect.
