Abstract
The invention relates to a novel high-efficient acid mist inhibitor and a preparation method thereof, and the novel high-efficient acid mist inhibitor is mainly used for inhibiting volatilization of acid mist during the acid cleaning and de-rusting process. The novel high-efficient acid mist inhibitor comprises the following components by weight percent: 2-15% of molecular film forming agent, 4-20% of emulsifier, 0-10% of solubilizer and 55-94% of solvent. The novel high-efficient acid mist inhibitor has the characteristics of low using quantity, high inhibition rate of the acid mist, good compounding property, environment friendliness, no toxicity, no harm and the like, and the mist inhibition effect is particularly more predominant under the conditions of high air humidity and high concentration of hydrochloric acid. The preparation method and the using method of the novel high-efficient acid mist inhibitor are simple, and the novel high-efficient acid mist inhibitor can not only be directly added into acid for use, but also be compounded with other acid cleaning additives for improving the mist inhibition performance of compounds.
Description
Technical field
The present invention relates to field of metal surface treatment, especially relate to acid mist evaporable inhibition in the pickling iron and steel process, is a kind of new and effective acid fog inhibitor of environmental protection.
Background technology
Acid pickling and rust removing is in industries such as metal processing, the mechanical workout manufacturing operation that is absolutely necessary, and using maximum pickle solutions now is to be prepared by hydrochloric acid.Hydrochloric acid is used for rust cleaning and has characteristics such as speed is fast, quality is good, but hydrochloric acid volatilizees easily, a large amount of acid mists in use can occur, not only the operator is caused actual bodily harm, simultaneously workshop appliance is caused serious corrosion.In order to reduce the volatilization of acid mist, the acid fog inhibitor that most of enterprises use suppresses the generation of hydrogen on the one hand by inhibiter, and another suppresses acid mist by the foam that tensio-active agent produces.Present most of producer feedback, these two kinds of method effects are all not obvious, and in atmospheric moisture when big or concentration of hydrochloric acid is higher, general acid fog inhibitor is difficult to reach the effect that acid mist suppresses.Patent CN101235266, CN101235267 disclose and have been used for the technology that the arid area suppresses moisture evaporation, have wherein used organic solvents such as sherwood oil, ether, can effectively suppress the evaporation of moisture.But, with an organic solvent environment is polluted, harmful to health simultaneously.It is primary solvent with water that the present invention prepares a kind of, does not contain the new and effective acid fog inhibitor of other harmful organic solvent, both can directly add in the acid and use, again can be composite with other pickling additives, and that improves compound presses down the mist performance.The present invention's preparation and use are simple, and compatibleness is good, and it is high to press down mist efficient, environmental protection, nontoxic.
Summary of the invention
The invention provides a kind of new and effective acid fog inhibitor and preparation method, suppress the volatilization of acid mist in the main acid cleaning process, be prepared from by molecular film-forming agent, solvent, emulsifying agent, solubilizing agent:
1. the molecular film-forming agent comprises C
12～18Fatty Alcohol(C12-C14 and C12-C18), C
11～18Lipid acid, the molecular energy of this structure is arranged at the acid solution surface orientation, forms fine and close unimolecular layer, thereby effectively suppresses the volatilization of acid mist.
2. make water as primary solvent, can select to add small amount of ethanol, propylene glycol or Virahol etc. as solubility promoter simultaneously, help the dissolving of molecular film-forming agent.
3. emulsifying agent comprises with Fatty Alcohol(C12-C14 and C12-C18), lipid acid, aliphatic amide being the alcoxylates and the ester salt thereof of hydrophobic group, the alkylammonium salt cationic emulsifier, one or more mixtures in the alkyl betaine tensio-active agent can be prepared into stable acid fog inhibitor with molecular film-forming agent emulsification.
4. solubilizing agent is nonionic surface active agent, C atomicity 8～12, and the EO number is 5～40.Solubilizing agent can act synergistically with emulsifying agent, strengthens the dissolving power of molecular film-forming agent and the compatibility in other pickling additives.
The invention provides a kind of each constituent mass of new and effective acid fog inhibitor consists of: molecular film-forming agent 2～15%, emulsifying agent 4～20%, solubilizing agent 0～10%, solvent 55～94%.
Preparation method of the present invention is:
(1) solvent of adding more than 60 ℃ in container adds emulsifying agent, solubilizing agent successively, is stirred to dissolving and even;
(2) continue under stirring condition, slowly to add heat and melt molecular film-forming agent, be stirred to temperature fast and drop to below 50 ℃ or till material viscosity sharply increases for liquid state.
(3) treat material cooling after, discharge tinning, promptly get new and effective acid fog inhibitor of the present invention.
Using method of the present invention is simple, both can directly add in the acid and use, and can be used as raw material again and other pickling additives are composite, and that improves product presses down the mist performance.
The present invention have consumption few, press down mist efficient height, characteristics such as compatibility is good, environment-protecting asepsis is harmless, can be big, show the remarkable fog effect that presses down in the condition that concentration of hydrochloric acid is too high in atmospheric moisture.
