Abstract
The invention provides an environment-friendly antirust cleaning liquid used in an iron casting working procedure. The environment-friendly antirust cleaning liquid comprises 1-10g/L of sodium phosphate, 1-5g/L of sodium silicate, 1-10g/L sodium benzoate, 2-10mL/L of polyethylene glycol, 0.4-3.0mL/L of alkylphenol ethoxylates, 1-10.0mL/L of OP emulsifier, 8-30mL/L triethanolamine, 0.3-4mL/L of phytic acid, 0.5-3mL/L of a silicone defoamer, 0.2-5mL/L of dodecyl dimethyl benzyl ammonium bromide and the balance of water. The environment-friendly antirust cleaning liquid does not contain sodium nitrite or chromate; and in the using process, no discharger occurs during the use process, and no environment pollution phenomenon occurs. The cleaning liquid provided by the invention is an environment-friendly antirust bactericidal antiseptic multifunctional metallic surface cleaning liquid and can be suitable for ultrasonic cleaning or high-pressure cleaning.
Description
Technical field
What the present invention relates to is a kind of cleaner for metal, and especially a kind of cast iron inter process cleans and antirust treatment solution.
Background technology
Rust prevention during manufacture refers to antirust in the course of processing, and namely Jia Gong component before entering next process, need to take provisional corrosion protection measure in logistics or the short process after each road manufacturing procedure.For mechanical component, to prevent that in cleaning process the rust that returns of dark rust and drying process from appearring in burn into.Sometimes, workpiece can be because of production requirement, after last operation processes, can deposit a couple of days to one month before entering subsequent processing, and at this moment clean-out system must have antirust ability.Present water-based antirust adopts nitrite and chromating technology more, but used main raw material has bigger toxicity.Though China is obtaining some progress aspect the consumption that reduces nitrite, rust-proof effect is also undesirable, and does not eliminate pollution problem, and the development of environment-friendly type water based anti-rusting agent has been subjected to domestic and international extensive concern.
Summary of the invention
The object of the present invention is to provide a kind of environmental protection, cleaning, antirust, sterilization, multi-functional antirust scavenging solution of cast iron inter process environment-friendly type such as anticorrosion of integrating.
The object of the present invention is achieved like this: its composition comprises sodium phosphate 1～10g/L, water glass 1～5g/L, Sodium Benzoate 1～10g/L, polyoxyethylene glycol 2～10mL/L, alkylphenol polyoxyethylene 0.4～3.0mL/L, OP emulsifying agent 1～10.0mL/L, trolamine 8～30mL/L, phytic acid 0.3～4mL/L, silicone defoamer 0.5～3mL/L, dodecyl dimethyl benzyl ammonium bromide 0.2～5mL/L, water surplus.

6) be a kind of organic phosphoric acid compounds that from plant, extracts, have good inhibition and complex ability, by with prescription in other component reaction form one deck transparent unimolecular film as thin as a wafer in Cast Iron Surface, stop corrosive medium to infiltrate the metallic surface effectively, prevent that cast iron from getting rusty, this tunic does not have influence to subsequent disposal.Phytic acid also has good resistance to hard water, can with water in metal ion form stable complex compound.
The present invention has substituted traditional use Sodium Nitrite fully as the cleaning of rust-preventive agent, no any discharging in the use, and the phenomenon of not having any contaminate environment takes place; The scavenging solution of this invention can be recycled, and the cast iron of handling can keep 15-45 days non-corrosives, is far superior to the cleaning performance of traditional technology.This scavenging solution can be used for ultrasonic cleaning or high pressure cleaning, does not have a large amount of foams and produces.This scavenging solution use temperature is 50-80 ℃.
Product of the present invention does not contain Sodium Nitrite and chromic salt, no any discharging in the use, and the phenomenon of not having any contaminate environment takes place; Scavenging solution of the present invention is a kind of environmental protection, cleaning, antirust, sterilization, rot-resistant Muitifunctional cleaning liquid for surface of metal.The applicable ultrasonic cleaning of this scavenging solution or high pressure cleaning.
Embodiment
For example the present invention is done more detailed description below:
Weigh 5g sodium phosphate, 3g water glass, 5g Sodium Benzoate solid, measuring 1.0mL alkylphenol polyoxyethylene, 15mL trolamine, 1.2mL phytic acid, 8mL polyoxyethylene glycol, 5mLOP emulsifying agent, 1.0mL silicone defoamer, 3mL dodecyl dimethyl benzyl ammonium bromide more respectively joins in the 1L tap water, it is filtered with vacuum pump with the circulation ability of swimming is many, get filtrate and namely can be used for cleaning.Get the above-mentioned filtrate of 50mL, Heating temperature to 60 ℃, (1.5cm * 2.0cm) takes out oven dry after putting into ready filtrate rinsing 1min, and room temperature is placed, and observing the time that the cast iron sheet begins to embroider erosion is 32 days to get a cast iron sheet.
