Problems solved by technology

[0004] The technical problem to be solved by the present invention: oil-based cleaning agents such as gasoline or halogenated hydrocarbons are often used for cleaning metal parts at present. They are easy to cause fires when used and are not easy to degrade and cause harm to the environment. The defect of poor rust resistance, the present invention uses biomass pepper as raw material, steam distillation extracts pepper oil and synthesizes pepper oil alkyl alcohol amide with diethanolamine under the catalysis of sodium hydroxide, and obtains metal net through esterification of phosphorus pentoxide The base material of the lotion, supplemented with a surfactant, is evenly sprayed on the calcined soda ash, and after a week of stacking, the biomass water-based metal cleaning agent is obtained. The biomass water-based metal cleaning agent prepared by the present invention can be directly mixed with water. , easy to biodegrade, solves the problem that the current oil-based detergent is easy to cause fire when used and is not easy to degrade and cause harm to the environment, and it has excellent anti-corrosion and anti-rust effects on metals after use

example 1

[0019] First weigh 15kg of fresh Zanthoxylum bungeanum, select and remove leaves and impurities, rinse it with deionized water for 5 times, lay it flat to dry, then put the dried Zanthoxylum bungeanum into the jet mill and crush it until the Zanthoxylum bungeanum is opened, and put the Zanthoxylum bungeanum in the refrigerator. Freeze overnight at -20°C, take it out and thaw it in a water bath at 80°C for 2 hours; put the thawed Zanthoxylum bungeanum into a steam distillation device, distill and extract for 8 hours to obtain a distillate, add its volume to the distillate Doubling ether and shaking and extracting 5 times, heating the combined extract to 40°C, distilling and recovering the ether to obtain Zanthoxylum bungeanum oil; weigh 450g of the Zanthoxylum bungeanum oil prepared above and 260g of diethanolamine and put them into a four-necked flask equipped with a stirrer, vent tube and thermometer In the flask, feed nitrogen into the flask to replace all the air in the flas...

Abstract

The invention relates to a preparing method for biomass water-based metal detergent and belongs to the technical field of detergent preparing. According to the preparing method, biomass peppers serve as the raw material; pepper oil is extracted through steam distillation, and the pepper oil and diethanol amine are synthesized into pepper oil alkylolamides under the catalysis of sodium hydroxide; a metal detergent base material is prepared through esterification of phosphorus pentoxide and is evenly sprayed onto sodium carbonate obtained after roasting by the aid of a surface active agent; and the biomass water-based metal detergent is obtained after heaping is conducted for a weak. The prepared biomass water-based metal detergent has the extremely good oil dirt removing capability on metal surface, and the oil dirt removing capability can reach 97% or higher; and degrading is easy, fire disasters cannot be caused, and extremely good antiseptic and antirust effects are achieved.

Description

technical field [0001] The invention relates to a preparation method of a biomass water-based metal detergent, belonging to the technical field of detergent preparation. Background technique [0002] Metal cleaning agent (hereinafter referred to as cleaning agent) is composed of one or several surfactants. Surfactant is a substance added to a liquid that can reduce the surface tension of the liquid, making the liquid wetting, penetrating, emulsifying, A series of surface activities such as foaming, solubilization and dispersion; it is a polar molecule, one end is a water-insoluble and lipophilic hydrocarbon group, and the other end is a hydrophilic polar group, that is, in the same molecule There are two different affinities, each of which has an independent effect and occurs simultaneously. It adsorbs or generates surface compounds on the metal surface, thereby changing the properties of the metal surface and changing its wettability. We use its wetting and penetration to...
