The invention provides a degreaser and a preparation method thereof. The degreaser comprises an emulsifier, a complexing agent, a surfactant and an adsorbent; and the adsorbent is aluminum hydroxide. The invention also provides a preparation method of the degreaser. The degreaser has an excellent degreasing effect, and has an extremely good protection effect on metals in a degreasing solution.
Description
Technical field
The invention belongs to field of surface treatment, particularly relate to a kind of degreaser and preparation method thereof.
Background technology
Cleaning oil removing operation often will be used in the process of Metal Production and processing.The various degreasing agent for metals often used at present, mainly contain strong acid, highly basic and tensio-active agent etc.They are all generally for the lighter oily waste treatment of metal surface, low to heavier greasy dirt cleaning efficiency, and show that scavenging period is long, effect is also very poor; Foam is a lot, cleans after affecting the effect of oil removing and oil removing; Containing various hazardous and noxious substances as Sodium Nitrite etc., contaminate environment, damages the health of operator; Easily corrosion is caused to more active metal such as aluminium etc., affect following process.
Publication number be CN 102108321A patent discloses a kind of degreasing agent for metal, it is characterized in that: comprise anion surfactant, nonionogenic tenside, solubilizing agent and inhibiter, wherein said inhibiter comprises the monocarboxylic acid and di-carboxylic acid that weight ratio is 10-1:1.This degreaser deoiling effect difference and have corrosion.
Summary of the invention
The present invention solves the technical problem that existing nonmetal degreaser deoiling effect is poor, corrodibility is large, provides degreaser that a kind of deoiling effect is good, corrodibility is little and preparation method thereof.
The invention provides a kind of degreaser, described degreaser comprises emulsifying agent, complexing agent, tensio-active agent and sorbent material; Described sorbent material is aluminium hydroxide.
Present invention also offers the preparation method of this degreaser, the method comprise complexing agent is water-soluble after add tensio-active agent, add emulsifying agent and sorbent material again after dissolving; Described sorbent material is aluminium hydroxide.
Degreaser of the present invention is a kind of weakly alkaline degreaser, almost neutral, to the metal of any not acid and alkali-resistance with nonmetally can reduce corrosion as far as possible, little to the corrodibility of metal and non-metallic material.Containing aluminium hydroxide in this degreaser, aluminium hydroxide can the grease of attract non-metals material surface fast, make grease can leave the surface of non-metallic material fast, reach the object of oil removing, simultaneously aluminium hydroxide can also form throw out with grease and passed through to filter, and improves the work-ing life of degreaser.
