Technical Field

The invention relates to the technical field of cleaning agents, and particularly relates to a foam type cleaning agent, and a preparation method and application thereof.

Background

In the processes of processing, transporting, using and the like of metal parts, the surfaces of the metal parts are often stained with grease, dust, metal chips, electrolyte, rust and other oil stains, the oil stains are easily formed into stubborn black colloid-shaped stubborn dirt with darker colors on the metal surfaces under the influence of the processing procedures, the using environment, the using time, the transporting process and other factors, and the good washing effect is difficult to achieve by using a common detergent.

The common cleaning agent in the market at present mostly adopts strong acid, strong base or surfactant and other formulas for cleaning, and has the following problems: (1) is harmful to human body, and does not meet the industrial requirements in the aspects of safety and environmental protection; (2) the cleaning effect is poor, and stains cannot be removed efficiently; (3) the material has certain corrosiveness and damages the equipment machinery; (4) the physical and chemical properties of the product do not reach the standard, the ignition point is low, the product is flammable and explosive, or the solidification point is high, the product can be used only by heating in a low-temperature environment, and the product has high limitation requirements on transportation, storage and use; (5) the volatility is high, the storage is difficult, and the use and storage processes are seriously wasted; (6) has strong pungent smell and seriously influences the operation of constructors.

In addition, the traditional heavy oil stain cleaning agent mainly adopts a soaking decontamination use mode, and has poor cleaning capability on heavy oil stains, so that the problems of large dosage of the cleaning agent, incomplete cleaning, more foams, difficult washing, great environmental pollution and the like are caused. Therefore, the foam type cleaning agent is used for cleaning heavy oil stains on metal parts, compared with a soaking liquid cleaning mode, foam can stay on the surface of the oil stains for a longer time, is more fully combined with oil stain permeation, can effectively decompose the stains, can achieve the effect of powerful stain removal, and has the characteristics of small using amount and strong stain removal capability.

However, the existing foam type heavy oil stain cleaning agent generally has the following problems: the surfactant with strong degreasing capability has strong oleophylic and lipophilic capabilities, slow foaming speed, small foam amount and instability; the surfactant with stronger foaming ability has poor oleophilic and lipophilic abilities, resulting in poor degreasing ability. The solvent of the cleaning agent also has the following problems: (1) the solvent with strong smell has strong polarity and good cleaning power, so the development of solvent-type low-odor or odorless cleaning agent is very difficult. (2) Solvents with high flash points have poor volatility and poor cleaning ability; the solvent with low flash point has fast volatility and better cleaning capability. (3) The solvent type cleaning agent generally has corrosivity to human bodies or rubber and the like, and the technical difficulty is high in how to develop a non-corrosive solvent type cleaning agent.

In view of this, the present application is specifically made.
