Problems solved by technology

Due to the monopoly of foreign technology, domestic foundry enterprises that introduce 3D printing technology can only rely on imports to obtain the required 3D sand printing binder and its supporting cleaning agent, which not only has to bear high costs, but also has certain risks.

Abstract

The invention relates to a novel efficient cleaning agent for cleaning a 3D molding sand printing head and a preparing method of the novel efficient cleaning agent.The cleaning agent is prepared from, by weight, 16-30% of isopropyl alcohol, 17-35% of methyl alcohol, 11-21% of ethyl alcohol, 13-23% of acetone, 8-16% of aviation kerosene and 2-8% of polyacrylic ester.The cleaning agent prepared through the method is low in viscosity, high in solubility, stable in performance and low in boiling point, does not react with resin chemically or cause harm to the human body or pollute the environment or cause swelling and corrosion damage to a circuit board in the printing head, prolongs the service life of the printing head, reduces the use cost of a 3D printer, and lays a foundation for further development of the 3D printing technology in the casting industry.

Description

technical field [0001] The invention relates to the field of casting auxiliary materials, in particular to a novel high-efficiency cleaning agent for cleaning 3D sand print heads and a preparation method thereof. Background technique [0002] Together with robots and the Internet, 3D printing technology is called the main symbol of the third industrial revolution. At present, some industrial-grade 3D printers have been used in foundry production services, mainly for rapid prototyping of castings, remaking molds, printing mold shells, sand cores, etc. At present, developed countries such as Germany and Japan have widely used 3D printing technology in the foundry industry, but in China, 3D printing technology is in its infancy, especially in the foundry industry, there are very few companies that use 3D printing technology to manufacture high-end precision castings. Technology will definitely lead the reform and development of the entire foundry industry in the 21st century. ...
