Cleaning agent for cleaning 3D-type sand printing head and preparation method of cleaning agent

Abstract

The invention relates to a cleaning agent for cleaning a 3D type sand printing head and a preparation method of the cleaning agent. The cleaning agent for cleaning the 3D type sand printing head comprises the following components in percentage by weight: 30-40% of sec-amyl alcohol, 18-26% of tetramethylurea, 18-22% of dipropyl ether, 6-14% of pinacolone, 9-15% of valerone and 0.6-1.4% of a stabilizing agent, wherein the stabilizer is propylene glycol methyl ether. The cleaning agent has the beneficial effects that raw materials relatively mild to human bodies and production environments are selected to reduce harms to the bodies and the environments to the utmost extent; the cleaning agent is small in surface tension and viscosity and strong in osmotic force, and can quickly dissolve resin crystals in the 3D-type sand printing head to ensure that the patency rate of an ore canal in the printing head is not less than 98.5%; the cleaning agent is stable in chemical property and cannot cause swelling and corroding actions on other parts of the printing head; the cleaning agent can reduce the production cost and prolong the service life of the 3D type sand printing head.

Description

Technical field [0001] The invention relates to the field of casting auxiliary materials, and in particular to a cleaning agent for cleaning 3D molding sand printing heads and a preparation method thereof. Background technique [0002] As one of the representative technologies of the third industrial revolution, 3D printing technology has attracted more and more attention from the industrial and investment circles. The application of 3D printing technology in the casting field is also becoming more and more extensive, most of which focus on rapid prototyping of castings, replica molds, printing mold shells, sand cores, etc. However, the common problems of high price and high maintenance cost of 3D sand printing equipment also restrict the promotion and application of 3D sand printing equipment. The most likely component of 3D printing equipment to cause equipment failure is the print head. Because it uses the inkjet printing principle, it requires very high cleanliness of t...

AI Technical Summary

Problems solved by technology

After consulting the literature and related reports, it is found that the cleanliness of the feed liquid is required to be below 2 μm. Once the print head is clogged, the entire printing equipment will not be able to continue to operate, resulting in huge waste of production costs.

At present, there is no cleaning agent that can effectively clean the 3D sand printing head in China. The cleaning and maintenance of the printing head can only be handled by foreign equipment manufacturers, which increases the production cost.
