Embodiment Construction

[0008] An environment-friendly biological water-based antirust liquid is characterized in that it is prepared by the following method:

[0009] Fresh camphor leaves and fresh pine leaves are put into a pulverizer and pulverized to obtain camphor leaf pulverization and pine leaf pulverization respectively, after camphor leaf pulverization and pine leaf pulverization are mixed in a ratio of 1:6 by mass, Add camphor leaf crushed material and pine leaf crushed material and mix 6 to 8 times the water for decoction, decoct for 3 hours and filter to obtain liquid A; take orange peel and pomelo peel and crush them, and mix them according to the mass ratio of 1:1. Proportionally mixed to obtain orange peel and grapefruit peel mixture, then add 25ml of acetic acid-sodium acetate buffer solution with pH=5 for every 1g of orange peel and grapefruit peel mixture, and then add 0.5mg per 1g of orange peel and grapefruit peel mixture Enzyme Accellerase 1500 was fermented and hydrolyzed for 72...

Abstract

The invention discloses an environment-friendly biological water-base antirust solution which is prepared by the following steps: respectively pulverizing fresh camphor tree leaves and fresh pine tree leaves to obtain a pulverized camphor tree leaf material and a pulverized pine tree leaf material, mixing in a mass ratio of 1:6, adding 6-8 times by mass of water into the mixture of the pulverized camphor tree leaf material and pulverized pine tree leaf material, decocting for 3 hours, and filtering to obtain a solution A; pulverizing orange peel and pomelo peel, mixing in a mass ratio of 1:1, adding an acetic acid-sodium acetate buffer solution, adding an enzyme Accellerase 1500, carrying out fermentation hydrolysis at 60-70 DEG C in a seal state for 72 hours, and filtering to obtain a solution B; mixing the solution A and solution B in a mass ratio of 2:1, adding a certain proportion of triethanolamine to perform sterilization treatment, and conditioning to obtain the environment-friendly biological water-base antirust solution.

Description

technical field [0001] The invention relates to the technical field of antirust liquid preparation, in particular to an environment-friendly biological water-based antirust liquid. Background technique [0002] Traditional water-based antirust solutions either use inorganic salts such as nitrite, silicate, and phosphate as neutral corrosion inhibitors, or use organic media such as alcohol amines, amides, and imidazolines as corrosion inhibitors. The former is low in price and has good anti-rust performance, but due to the carcinogenicity of nitrite, it causes great environmental pollution and has tended to be eliminated. Although the toxicity of the latter is greatly reduced, the cost is high and the cost of pollution control is high. Under this background, this environmentally friendly biological water-based anti-rust solution was born as needed. In our long-term experimental research, we found that some The fruit peel of the plant has good rust resistance to steel. If we ...
