Abstract
The invention relates to a low-alkali phosphorous-free degreaser, which belongs to the technical field of cleaning agents for surfaces of metal materials and consists of raw materials with the following weight part ratios: 0.5 to 5 parts of surface active agent, 1 to 8 parts of sodium sulfate, 0.5 to 6 parts of sodium gluconate, 1 to 16 parts of disodium versene acid and 1 to 15 parts of sodium silicate. The degreaser has the advantages that the excellent infiltration capacity embodies the ideal oil removing speed and cleaning effect; the degreaser can adapt to low temperature (20 to 48 DEG C), thus being beneficial to saving energy resources. When in use, the degreaser has less foams and can prevent the alkaline fog from eroding equipment and influencing on the environment owing to the small amount of alkali in the formula.
Description
Technical field
The invention belongs to the metallic material surface detergent technical field, be specifically related to a kind of low-alkali non-phosphate degreasing agent.
Background technology
Because the surface of cold-rolled steel sheet has rolling greasy dirt and other residue that stays when rolling, therefore in that cold-rolled steel sheet is put to must be with rolling greasy dirt and the removing of other residue before zinc-plated, otherwise can't obtain that light is exquisitely carved, bonding force is excellent and corrosion resistance nature ideal zinc coating, industry claims the pre-treatment that is treated to before zinc-plated.Grease-removing agent is being filled the post of makes cold-rolled steel sheet obtain the effect on the surface of a cleaning before zinc-plated, and its mechanism of action is to remove by rolling greasy dirt, slushing oil and other residue that saponification reaction will attach at surface of steel plate.
Past people is paid close attention to its deoiling effect to grease-removing agent morely; yet environment protection is attached undue importance to one thing to the neglect of the other to some extent; for example be no lack of in Chinese patent literature and be seen in the relevant technical scheme that phosphorous grease-removing agent is arranged, the disclosed degreasing agent for cleaning stainless steel of Granted publication CN1200143C, publication number CN101191233A introduce, and to roll hard volume degreasing agent for cleaning and preparation and using method thereof be illustration.Along with the increase of people to the responsibility consciousness of environment protection, occupied an leading position by agent of non-phosphate degreasing in the market of fading out gradually because phosphorous grease-removing agent has harm to environment.Many technical schemes about agent of non-phosphate degreasing are arranged in Chinese patent literature, only the applicant just applies for there are two, and their application number is respectively 200810023114.2 (agent of non-phosphate degreasing) and 200810196573.0 (additive of agent of non-phosphate degreasing and the agent of non-phosphate degreasing that contains this additive).In addition; Granted publication CN1118554C recommends to have agent of non-phosphate degreasing and manufacture method; do not contain phosphorus in the prescription of this patented technology scheme; very favourable to environment protection; but have the material choice requirement harshness that the applicant concludes in the background technology of 200810023114.2 patent applications; constitute trouble to making, complex process, manufacturing processed is tediously long and energy consumption big and be not suitable for enterprise makes personal drawback by oneself on production line.CN1782134A has disclosed the alkaline detergent composition that is used for steel disc, and said composition contains alkali reagent and at least a Voranol EP 2001, and/or at least a polyoxyalkylenes ether.Owing to contain the alkaline matter of high density in the composition of being recommended, thereby exist the working temperature height in the oil removing process to steel disc, not only cause the big and cost for wastewater treatment height of energy consumption, and cause the alkali mist and contaminated equipment and environment.With regard to working temperature, although the summary of the invention hurdle of the Instructions Page 2 of this patent application the 3rd row claim, be not higher than 50 ℃ can wash temperature is reduced to from previous 80 ℃, yet be to be difficult to even to be beyond one's reach in the application process of reality.
Summary of the invention
Task of the present invention is to provide a kind of alkali content low and without phosphorus and use and embody the excellent permeation ability and cleaning performance is good, foam is few, adaptive temperature is low and save energy, avoid alkali mist etching apparatus and undermine the low-alkali non-phosphate degreasing agent of environment.
Task of the present invention is finished like this, a kind of low-alkali non-phosphate degreasing agent, and it is that raw material by following weight part ratio constitutes: tensio-active agent 0.5-5 part; Sodium sulfate 1-8 part; Sunmorl N 60S 0.5-6 part; Disodium ethylene diamine tetraacetate 1-16 part; Water glass 1-15 part.
In a specific embodiment of the present invention, described tensio-active agent is any one or more than one the combination in alcohol ether carboxylate, multi-hydroxy polyether and the octyl phenyl Soxylat A 25-7.
In another specific embodiment of the present invention, described sodium sulfate is anhydrous sodium sulphate.
In another specific embodiment of the present invention, described water glass is the modification sodium disilicate.
Technical scheme provided by the present invention is compared with the phosphorous or high alkali cleaner in the prior art, has the good penetration ability and can embody ideal and remove speed oil and cleaning performance; Adaptive temperature low (20-48 ℃) and help save energy; Because the alkali content in the prescription, foam is few and can prevent alkali mist etching apparatus and cause influence to environment during use.
