Embodiment 1

[0037] Embodiment 1, a kind of steel bar rust inhibitor made with vegetable waste extract, is made by following steps,

[0038] Reclaimer:

[0039] Collect vegetable waste parts such as cucumber stems and leaves;

[0040] Prepare cucumber stem and leaf powder:

[0041] Dry the vegetable waste part at a constant temperature of 60 degrees; after crushing, sieve through a 100-mesh sieve; obtain cucumber stem and leaf powder;

[0042] Prepare the mixture: dissolve the cucumber stem and leaf powder in 0.5mol / L sodium hydroxide solution according to the mass ratio of 1:100, and stir evenly; the mixture is obtained

[0043] Stand still: put the mixture in a 25-degree water bath for 12 hours, and obtain the extract after filtering;

[0044] Adjust the pH value to 9.5 with NaHCO3;

[0045] Distillation: Distill under reduced pressure at 120 degrees for 24 hours to obtain the rust inhibitor for steel bars.

Embodiment 2

[0046] Embodiment 2, a kind of steel bar rust inhibitor made with vegetable waste extract, is made by following steps,

[0047] Reclaimer:

[0048] Collect vegetable waste parts such as cucumber stems and leaves;

[0049] Prepare cucumber stem and leaf powder:

[0050] Dry the vegetable waste part at a constant temperature of 60 degrees; after crushing, sieve through a 100-mesh sieve; obtain cucumber stem and leaf powder;

[0051] Preparation of mixture: Dissolve cucumber stem and leaf powder in 0.5mol / L sodium hydroxide solution at a mass ratio of 1:100, and stir evenly; leave the mixture to stand: put the mixture in a 50-degree water bath for 6 hours, filter and extract liquid;

[0052] Adjust the pH value to 9.5 with NaHCO3;

[0053] Distillation: distillation under reduced pressure at 150°C for 12 hours to obtain steel bar rust inhibitor.

Embodiment 3

[0054] Embodiment 3: a kind of steel bar rust inhibitor made with vegetable waste extract, is made by following steps,

[0055] Reclaimer:

[0056] Collect vegetable waste parts such as cucumber stems and leaves;

[0057] Prepare cucumber stem and leaf powder:

[0058] Dry the vegetable waste part at a constant temperature of 60 degrees; after crushing, sieve through a 50-mesh sieve; obtain cucumber stem and leaf powder;

[0059] Preparation of mixture: Dissolve cucumber stem and leaf powder in 1 mol / L sodium hydroxide solution at a mass ratio of 1:100, and stir evenly to obtain a mixture.

[0060]Stand still: put the mixture in a 50-degree water bath for 8 hours, and obtain the extract after filtering;

[0061] Adjust the pH value to 9.5 with NaHCO3;

[0062] Distillation: distillation under reduced pressure at 150°C for 12 hours to obtain steel bar rust inhibitor.

Abstract

The invention relates to the technical field of building material and vegetable waste treatment. The production method of a reinforcing bar rusty retardant agent produced by vegetable waste extracts comprises the following steps: preparing vegetable waste parts of cucumber stems, leaves and the like into powder, adding the powder into an alkaline solution, and stirring uniformly in the deoxygenated state, so as to obtain a mixture; the production method further comprises the step of standing, namely carrying out a constant-temperature water bath while standing, and further comprises the step of distilling, namely filtering an extracting solution, then carrying out distillation, and removing water therein to obtain the reinforcing bar rusty retardant agent.

Description

technical field [0001] The invention relates to the technical field of building materials and vegetable waste treatment, and provides a steel bar rust inhibitor made of vegetable waste extract, and a preparation method and an application method of the rust inhibitor. Background technique [0002] The development of greenhouse vegetables has made an indelible contribution to the road to prosperity for Chinese rural farmers. However, with the development of the vegetable industry, more and more vegetable waste is produced. For vegetable waste, the current main treatment methods are landfill, incineration, composting, etc. However, only these methods cannot completely digest the vegetable waste in the environment, and these treatment methods still have certain defects, such as landfill method will produce leakage The liquid will further pollute the groundwater, and incineration will produce toxic and harmful gases such as dioxin, and the ash after incineration has a huge poison...
