preparation example Construction

[0028] The invention discloses a method for preparing a liquid metal non-stick layer, mainly by attaching the reactant of an ortho-dihydroxyphenol compound and an amine compound in a dissolved state to the surface of an object to be in contact with liquid metal. Forms a non-stick layer on the surface. Wherein, the present invention mainly utilizes the reaction between the amino groups in ortho-dihydroxyphenols and amines, and the chemical molecular structure of ortho-dihydroxyphenols is as follows: figure 1 As shown, the chemical molecular structure of the amino group is as figure 2 shown.

[0029] The non-stick layer in the present invention is produced by the reaction of o-dihydroxyphenols and amino groups, has stable properties and irreversible reactions, and can maintain its layer structure for a long time. And the utensil prepared by this method has a non-stick layer attached to its surface, which can obviously reduce the adhesion residue of liquid metal on the utensil...

Abstract

The invention discloses a preparation method of a liquid-state metal non-stick layer and a utensil without sticking of liquid-state metal. The preparation method comprises the following steps: attaching a reactant under a dissolved state of an o-dihydroxyphenol compound and an amine compound on the surface of an object which is in contact with the liquid-state metal, so as to form the non-stick layer on the surface of the object. According to the preparation method, the non-stick layer is generated by taking o-dihydroxyphenol to react with amino in amine, properties are stable and reaction isirreversible; a layer structure can be kept for a long time. The non-stick layer is attached on the surface of the utensil so that attachment residues of the liquid-state metal on the surface of the utensil can be remarkably reduced, and pollution of the liquid-state metal on a container and wastes of the liquid-state metal are extremely avoided; meanwhile, with regard to an output utensil of theliquid-state metal, the risk probability that ink is difficult to output and the output ink is blocked, caused by the fact that the liquid-state metal is attached on the surface of a pipeline, is reduced.

Description

technical field [0001] The invention belongs to the technical field of liquid metal application, and in particular relates to a preparation method of a liquid metal non-adherent layer and an appliance not adhering to liquid metal. Background technique [0002] As a new functional material with unique physical and chemical properties, liquid metal has developed rapidly in recent years. 3D printing and printing processes based on liquid metal have been developed one after another. However, in the process of research and development and production, liquid metal is easy to adhere to the surface of various utensils. , causing container pollution, a large amount of waste of materials, and high production and research and development costs. [0003] Moreover, during the liquid metal 3D printing process, the liquid metal discharges the ink downward through the action of gravity, but because the liquid metal is easy to adhere to the ink cartridge, when the liquid metal stock in the i...
