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, in particular to a cleaning agent for cleaning 3D 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 industry and investment circles. The application of 3D printing technology in the casting field is also more and more extensive, most of which are concentrated in the rapid prototyping of castings, reworking molds, printing mold shells, and sand cores. However, due to the high price and high maintenance cost of 3D sand printing equipment, the popularization and application of 3D sand printing equipment are also restricted. The most prone component of 3D printing equipment to cause equipment failure is the print head. Because of its inkjet printing principle, the cleanliness of the material and liquid is very high. Af...
