| titleOfInvention | A method of laser sintered 3D printing precoated sand is prepared for adhesive with sugar |
| abstract | The invention discloses a kind of methods for preparing laser sintered 3D printing precoated sand with sugar for adhesive, it is characterized in that, after nice foundry sand is washed with water first, it is immersed in the aqueous solution for the cetyl trimethylammonium bromide that mass percentage concentration is 5 ~ 6%, it is placed at room temperature for 48h, it is separated by solid-liquid separation, it is dry, obtain pretreatment nice foundry sand；Then, in the reactor, it is added by mass percentage concentration, water: 38% ~ 44%, white sugar: 2% ~ 6%, pretreatment nice foundry sand: 52% ~ 56%, diethylenetriamines: 0.2% ~ 1.0%, polyethylene glycol: 0.2% ~ 2.0%, the sum of each component is absolutely, strong stirring, temperature rises to 160 ~ 170 DEG C, until moisture evaporates, grinds, 120 meshes are crossed, laser sintered 3D printing precoated sand is obtained.The precoated sand using it is laser sintered can straight forming, good fluidity, formed precision is high, and has simple process, and production cost is low, easy to industrialized production. |
