Abstract
The invention relates to a metal phosphating pretreatment agent. The metal phosphating pretreatment agent consists of main materials, a surfactant and a complexing agent. Each liter of the metal phosphating 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 fatty alcohol-polyoxyethylene ether, 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 metal phosphating pretreatment agent is prepared by weighing the components in the formula and stirring the components uniformly. In the metal phosphating 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 a kind of metal phosphorizing pretreating reagent.
Background technology
Traditional phosphatization pre-treating process normally directly adopts technical hydrochloric acid directly to handle.Such processing can only be handled newly-generated rust.Owing to other reasonses such as depositing of metal material, the rust of metallic surface and greasy dirt are bonded together, intractable is clean.At 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 metal phosphorizing pretreating reagent, have added complexing agent simultaneously, 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 metal phosphorizing pretreating reagent.Introduce surfactant in this metal phosphatization pretreating reagent, strengthened the rust cleaning of metal phosphorizing pretreating reagent, degreasing performance, added complexing agent simultaneously, 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 metal phosphorizing pretreating reagent is made up of material of main part, tensio-active agent and complexing agent, and the component and the weight part that contain in every liter of metal phosphorizing pretreating reagent are:
