Abstract
The invention relates to an environment-friendly comprehensive pretreatment agent. The environment-friendly comprehensive pretreatment agent consists of main materials, a surfactant and a complexing agent. Each liter of the environment-friendly comprehensive pretreatment agent contains the following components in part by weight: 700 to 800 grams of industrial hydrochloric acid, 10.0 to 14.0 grams of acetic acid, 2.0 to 4.0 grams of polyethylene glycol, 2.0 to 4.0 grams of alkyl sodium sulfonate, 4.0 to 6.0 grams of triethanolamine, 3.0 to 5.0 grams of ethylene diamine tetraacetic acid tetrasodium salt, 7.0 to 10.0 grams of potassium sodium tartrate and the balance of water. The environment-friendly comprehensive pretreatment agent is prepared by weighing the components in the formula and stirring the components uniformly. In the environment-friendly comprehensive pretreatment agent, the surfactant is added, so the capacity of removing rust and oil dirt adhered to the surface of the metal is enhanced, the effect of treating the oil dirt is good, hydrochloric acid mist generated in the working process is reduced, the working environment is improved, and the service life of bath solution is prolonged.
Description
Technical field
The present invention relates to chemical field, be specifically related to the front synthesized environmental protection comprehensive pretreatment agent of a kind of metal phosphorizing.
Background technology
Traditional phosphatization pre-treating process normally directly adopts technical hydrochloric acid directly to process.Such processing can only be processed newly-generated rust.Owing to other reasonses such as depositing of metal material, the rust of metallic surface and greasy dirt are bonded together, be difficult to process clean.For above situation, we invent this treatment agent formula, and this treatment agent can overcome the weak point in the traditional method, has introduced surfactant, have strengthened the performance of Environmental-protection comprehensive pretreating reagent, have added simultaneously complexing agent, have prolonged the duration of service of tank liquor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of Environmental-protection comprehensive pretreating reagent.Introduce surfactant in this Environmental-protection comprehensive pretreating reagent, strengthened the rust cleaning of Environmental-protection comprehensive pretreating reagent, detergency ability, added simultaneously complexing agent, prolonged the duration of service of tank liquor.
The technical solution used in the present invention is as follows for achieving the above object:
A kind of Environmental-protection comprehensive pretreating reagent is comprised of material of main part, tensio-active agent and complexing agent, and the component and the weight part that contain in every liter of Environmental-protection comprehensive pretreating reagent are:
31% technical hydrochloric acid 700-800g
Acetic acid 10.0-14.0g
Polyoxyethylene glycol 2.0-4.0g
Alkyl sodium sulfonate 2.0-4.0g
Trolamine 4.0-6.0g
Tetrasodium ethylenediamine tetraacetate 3.0-5.0g
Seignette salt 7.0-10.0g
All the other are water.
Described Environmental-protection comprehensive pretreating reagent is comprised of material of main part, tensio-active agent and complexing agent, it is characterized in that: the component and the weight part that contain in every liter of Environmental-protection comprehensive pretreating reagent are:
31% technical hydrochloric acid 600g
Acetic acid 12.0g
Polyoxyethylene glycol 3.0g
Alkyl sodium sulfonate 3.0g
Trolamine 5.0g
Tetrasodium ethylenediamine tetraacetate 4.0g
Seignette salt 8.0g
All the other are water.
Compound method: each the composition weighing in will filling a prescription is good, and mixing and stirring gets final product.
Beneficial effect of the present invention:
Environmental-protection comprehensive pretreating reagent of the present invention, introduced surfactant, strengthened the performance of Environmental-protection comprehensive pretreating reagent, greasy dirt and the iron rust time of removing the metallic surface are short, effective, reduced the hydrochloric acid mist that produces in the working process, improve Working environment, simultaneously, prolonged the work-ing life of tank liquor, save cost, improved degreasing, rust cleaning efficient.
