Abstract

The invention discloses a preparation method for a natural rust remover. The preparation method comprises the following steps: (1) taking a water-alcohol mixture for crushing hedyotis caudatifolia as a solvent for leaching, carrying out reduced pressure concentration on a leaching solution, and recovering the solvent until an alcohol smell disappears; (2) extracting the solution free from the alcohol smell, which is obtained in the step (1), by virtue of n-butyl alcohol to obtain a corresponding extracting solution, and carrying out reduced pressure concentration on the extracting solution to obtain a dry extract; and (3) washing the dry extract obtained in the step (2) through a macroporous resin until an eluting solution is colourless, then eluting by virtue of an ethyl alcohol solution with a volume concentration of 30%, collecting the eluting solution, and carrying out concentration and drying to obtain the rust remover. The natural rust remover prepared by the method disclosed by the invention is simple and convenient to prepare, safe and non-toxic, good in rust removal function for metal, and specially applicable to rust removal for kitchen utensils.

Description

A kind of preparation method of natural rust remover
Technical field
The invention belongs to rust remover technical field, more particularly to a kind of preparation method of natural rust remover.
Background technology
Herba Hedyotis Lanceae (Hedyotis caudatifolia Merr.et Metcalf), is Rubiaceae plants of Hedyotis sword The herb of auricle grass, alias teenager is red, long-tail Auricled Hedyotis Herb, tea in thousand, postpartum tea, tuberculosis grass, be a kind of Guangxi traditional herbal medicine, have only The effects such as coughing resolving sputum, invigorating the spleen disperse accumulations, is usually used in treatment bronchial astehma, bronchitis, tuberculosis spitting of blood, infantile malnutrition, bruise and swells Bitterly, traumatism and bleeding etc..The research that Herba Hedyotis Lanceae is related at present mainly has the GC-MS of microstructural research, volatile oil component Analysis and protective effect of its extract to liver.
Metal (including stainless steel) is placed under outdoor or open-air condition or is got rusty easily during permanent use, and influence is outer While sight, can also influence to use.Traditional chemical derusting is usually using strong acid, the health and corrosion surrounding of influence user of service Equipment and environment;The residues for largely producing simultaneously, contaminated soil and environment.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of natural rust remover, the preparation side of the rust remover Method is simple and convenient, rust remover safety non-toxic, while with good rust removing function, does not cause the pollution of environment and operating personnel strong The infringement of health.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that:
A kind of preparation method of natural rust remover, comprises the following steps:
(1) Herba Hedyotis Lanceae is crushed, is placed in solvent and extracts, solvent is the mixture of water and alcohol, alcohol is methyl alcohol or ethanol In one kind;Gained leaching liquor is concentrated under reduced pressure, recycling design is to without alcohol taste;
(2) step (1) gained is obtained into corresponding extract without alcohol taste solution with extracting n-butyl alcohol, extract is depressurized Concentration, obtains powdered extract;
(3) by step (2) gained powdered extract by macroreticular resin, be washed to eluent it is colourless after, then with volumetric concentration Ethanol solution for 30% is eluted, and collects eluent and concentrate drying is the rust remover.
The Herba Hedyotis Lanceae uses the herb of Herba Hedyotis Lanceae plant.
The solvent of the step (1) is ethanol solution or methanol solution that volumetric concentration is 60%..
The Herba Hedyotis Lanceae of the step (1) and the mass ratio of solvent are 1: 8.
Compared with prior art, beneficial effects of the present invention are:
A kind of preparation method of natural rust remover of the present invention is right with natural plants Herba Hedyotis Lanceae extract as main component Metal has good rust removing function including stainless steel product, and safety non-toxic, without aggressive, does not cause environmental pollution.
Specific embodiment
The present invention is described in further detail with reference to embodiments, but is not constituted to rights protection scope of the present invention Limitation.
Embodiment 1:
Herba Hedyotis Lanceae sample used, using the herb of Herba Hedyotis Lanceae plant, with second that volumetric concentration is 60% after crushing Alcohol solution is extracted as solvent to Herba Hedyotis Lanceae, and the mass ratio of Herba Hedyotis Lanceae and solvent is 1: 8, recycling design to nothing Alcohol taste;Gained, with extracting n-butyl alcohol, is 1: 1 without alcohol taste solution and n-butanol volume ratio without alcohol taste solution, and extract is concentrated under reduced pressure Obtain powdered extract;On powdered extract D101 types macroreticular resin wash-out, be washed to eluent it is colourless after, then with volumetric concentration be 30% Ethanol solution wash-out, collect eluent and concentrate drying and obtain final product the rust remover, the rust remover and water by weight 5: 1 are matched somebody with somebody Than resulting solution is applied to rustless steel container rusty part, after standing 30 to 60 minutes, is rinsed with clear water, and rusty stain is removed and nothing Iron mold.
