Abstract
The invention relates to an oil and rust removing agent for metal, in particular to an environment friendly oil and rust removing agent for steels, belonging to the technical field of chemical engineering, comprising hydrochloric acid, oxalic acid, surfactant, complexing agent, and corrosion inhibitor, wherein, hydrochloric acid is used as major influencing factor for rust removing, the adding of oxalic acid obviously reduces acid mist, and the surfactant has the effects of removing oil, inhibiting mist and the like. Because of the synergy of the ingredients, the process has the advantages of normal temperature, rapidness, high efficiency, environmental protection and the like.
Description
Technical field
The present invention relates to a kind of metal degreasing derusting agent, be specifically related to a kind of environmental protection shaped steel oil-removing rust-removing agent, belong to chemical technology field.
Background technology
Iron and steel is a requisite material in modern society's economic life, in industrial and agricultural production and people's lives, have a wide range of applications, but various steel products surface is subject to the influence of atmospheric medium and other factors and rust corrosion is approximately 20%～30% of iron and steel annual production.In order to protect steel product, prolong its work-ing life, must carry out rotproofing to its surface.When steel product is taked various anti-corrosion measure, degreasing and rust removal is a necessary step, traditional oil removing and rust cleaning operation generally are proceed step by step, facility investment is big, operation is many, efficient is low, it is long to ask when handling, energy consumption is big, acid mist is serious, make the workman endure the erosion of obnoxious flavour to the fullest extent, processing work easily produces excessive erosion and hydrogen embrittlement, and has a strong impact on surrounding enviroment.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of environmental protection shaped steel oil-removing rust-removing agent is provided, it includes hydrochloric acid, oxalic acid, tensio-active agent, complexing agent, inhibiter, content of hydrochloric acid is main rust cleaning influence factor, the adding of oxalic acid obviously reduces acid mist, and tensio-active agent has effects such as deoiling, press down mist.Since the synergy of each component of prescription make this technology have normal temperature, fast, characteristics such as efficient, environmental protection.
The present invention realizes with following technical scheme: a kind of environmental protection shaped steel oil-removing rust-removing agent, it is characterized in that: it includes hydrochloric acid, oxalic acid, tensio-active agent, complexing agent, inhibiter, and described tensio-active agent is polyoxyethylene octylphenol ether and fatty alcohol-polyoxyethylene ether; Described complexing agent is a disodium ethylene diamine tetraacetate; Described inhibiter is a urotropine; The weight part of each raw material of oil-removing rust-removing agent is: hydrochloric acid 18-20 part, oxalic acid 5-7 part, polyoxyethylene octylphenol ether 18-20 part, fatty alcohol-polyoxyethylene ether 20-22 part, disodium ethylene diamine tetraacetate 20-22 part, urotropine 3-4 part.
Urotropine oxalic acid needs to add the certain inhibiting fog agent of people owing to use hydrochloride derusting acid mist can occur separately for this reason.Inhibiting fog agent can make the surface tension of solution reduce, and the bioactive molecule of oriented adsorption forms the unimolecular film of one deck densification on liquid-gas interface, thereby prevents escaping of acid mist effectively, the protection production environment.The adding of oxalic acid not only can be played the effect that suppresses acid mist, and rust cleaning speed is also accelerated greatly, this is because oxalic acid can not only react with the oxide compound of iron, and can also with the further complexing of iron ion, generate more stable ironic oxalate complex ion, guarantee the concentration of hydrochloric acid, stoped the generation of acid mist, improved rust cleaning efficient.The key that tensio-active agent normal temperature improves down oil removal efficiency is the selection and the ratio optimization of tensio-active agent, and tensio-active agent just can significantly reduce the surface tension of water when lower concentration very, and reaching can be in conjunction with the formation micella behind the finite concentration.Utilize this specific character of tensio-active agent, can reach oil removing, wetting, press down mist, anatonosis, thickening, purpose such as wetting.Add the HS and can remove on the one hand grease on the substrate surface, can reduce the tension force at iron and steel and scavenging solution interface on the other hand, the easier effusion of the bubble of generation is difficult for generation " hydrogen embrittlement "; Moreover on liquid level, form one deck foam, and stop the effusion of acid mist, reduce the consumption of acid, reduce environmental pollution.As permeation promoter the intensive osmotic effect is arranged, can rapid osmotic arrive between steel and the oxide skin, drive acid endosmosis together, oxide skin is produced from peeling off, promptly come off, reach the purpose of quick derusting with bulk.
Advantage of the present invention is: this Recipe principal feature is the comparison environmental protection, and solution property is stable, does not almost have acid mist in the production, has improved the degreasing and rust removal Working environment.Operation is efficient fast down, technology is simple for normal temperature, and steel iron rust behind this prescription degreasing and rust removal obviously comes off.
The invention will be further described below in conjunction with embodiment;
