Embodiment 1

[0043] Prepare 20 g of sodium lignosulfonate and add 100 ml of deionized water to obtain a cleaning agent main solution. The solution was placed under a water bath at 80° C. for 1 hour under magnetic stirring, and then stood still for preparation. Prepare 10 g of glycerol and 7.5 g of agar, add 200 ml of deionized water to get thickener. Stir the thickener with a mechanical stirring device at a stirring speed of 800 rpm for 1 hour, and place the thickener in a water bath at 80° C. to keep warm to facilitate the combination of agar and glycerin, and then stand still for preparation. Add 2 g of sodium sulfate and 1 g of sodium citrate to 100 ml of deionized water, place it in a water bath at 80° C. and stir it magnetically for 1 h. Take 5g of octylphenol polyoxyethylene ether and 5g of fatty alcohol polyoxyethylene ether sodium sulfate and add it to 100ml of deionized water, place the main body of the obtained surfactant in a water bath at 50°C and carry out magnetic stirring f...

Abstract

The invention particularly relates to a cleaning agent for a metal slurry cylinder of a 3D printer and a preparation method of the cleaning agent, and belongs to the technical field of special cleaning agents. The cleaning agent comprises the following components in parts by weight: 50-75 parts of a sodium lignin sulfonate solution, 5-15 parts of a surfactant, 10-30 parts of a thickening agent and 5-15 parts of a builder. Through the synergistic effect of the components, the prepared cleaning agent has the technical effects of high activity, moderate viscosity, high cleaning speed, high efficiency and no corrosion to equipment, and specifically, the cleaning agent is more stable in flowing, higher in cleaning efficiency and shorter in cleaning time in the using process; and the cleaning agent is basically free of residues, has no corrosion effect on equipment, does not need to be heated in the cleaning process, and meanwhile, the raw materials of the cleaning agent are cheap and easy-to-obtain articles in the market, so that the cost of the cleaning agent is relatively low.

Description

technical field [0001] The invention belongs to the technical field of special cleaning agents, and in particular relates to a cleaning agent for metal paste cylinders of 3D printers and a preparation method thereof. Background technique [0002] Now 3D printing technology has gradually matured, and there are various forms of 3D printing, such as laser near net shaping, laser selective melting forming technology, electron beam melting forming technology, fused deposition forming technology and so on. These traditional additive manufacturing technologies have been developed for decades, and the research on advanced material additive manufacturing and new methods is of great significance to the innovation of 3D printing technology. Metal paste 3D printing refers to the metal paste 3D printing forming technology developed based on droplet injection forming technology and fused deposition forming technology. Compared with laser near-net shaping technology, it has great advantag...
