[0027] The preparation technology of full-color sandstone dyestuff comprises the following steps:

[0028] 1. Prepare a solution of 8.0% to 20.0% binder by commercially available binder and pure water, and heat at 80~150°C for 0.1~10h under the stirring condition of 50~300r / min to prepare the binder; add 4N Sodium hydroxide aqueous solution, adjust the pH to 9.5-10.0, according to the mass ratio of the dye powder and the deionized water as 1:1, under the condition of 200-1000r / min, mechanically stir for 0.5-5.0h, Get Dye Supplies for Full Color Sandstone Dye.

[0029] 2. According to the mass percentage of each component of the raw material of the full-color sandstone product, weigh 60.0% to 85.0% of the main powder and 2.0% to 15.0% of the coagulant and add them to the mechanical mixing equipment in sequence in proportion, and mix them evenly by ball milling. Makes a powder of full-color sandstone dye. Wherein, the main powder and the coagulant are both commercially available...

Embodiment 1

[0036] 1. Weigh 0.24Kg of cornstarch, add 2.76Kg of deionized water to the beaker according to the ratio of cornstarch mass content of 8.0%, place the heating temperature at 115°C and the stirring speed at 175r / min, heat treatment for 5.0h, A starch solution is obtained. After slowly cooling down to room temperature, prepare it.

[0037] 2. Add the dye slurry consisting of 1.5Kg of C.I reactive red 218 and 1.5Kg of deionized water to the solution in step 1, and then continue to add 4N aqueous sodium hydroxide solution to adjust the pH of the solution to 9.5-10.0. Stir for 5.0 hours at a speed of 200 r / min to obtain a uniformly mixed full-color sandstone dye consumable.

[0038] Three, the preparation of full-color sandstone dye powder, according to the ratio that mass content accounts for sandstone powder consumable 60.0% and 15.0%, the purity after drying is 4.8Kg of 200 mesh calcium carbonate of 95.0%, 1.2Kg of aluminum sulfate of 98.0%, successively Put it into the QM-2SP...

Embodiment 2

[0043] One, take by weighing 0.42Kg potato starch, according to the ratio that potato starch mass content is 14.0%, add 2.58Kg deionized water in the beaker, place heating temperature 80 ℃, under the condition of stirring speed 300r / min, heat treatment 0.1h, A potato starch solution is obtained. After slowly cooling down to room temperature, prepare it.

[0044] 2. Add the dye slurry consisting of 1.5Kg of C.I reactive red 218 and 1.5Kg of deionized water to the solution in step 1, and then continue to add 4N aqueous sodium hydroxide solution to adjust the pH of the solution to 9.5-10.0. Stir for 2.7 hours at a speed of 600r / min to obtain a uniformly mixed full-color sandstone dye consumable.

[0045] Three, the preparation of full-color sandstone dye powder, according to the ratio of mass content accounting for sandstone powder consumables 85.0% and 2.0%, the purity after drying is 6.8Kg of 800 mesh gypsum powder of 99.0%, 0.16Kg of potassium sulfate of 99.5%, successively ...

Abstract

The invention discloses a full-color sandstone dye for 3DP (three dimensional printing) and a forming method of a full-color sandstone dye product. The full-color sandstone dye comprises 15%-25% by mass of dye powder, 60.0%-85.0% by mass of main body powder, 2.0%-15.0% by mass of an accelerator and 8.0%-20.0% by mass of a binder. A traditional dye is subjected to chemical grafting, surface active points are increased, and the dye is mixed with the accelerator, the binder and the like. According to a process, the adhesiveness of the dye to the surfaces of sandstone particles is improved effectively while the dye dispersing effect is improved, and the bleeding fastness and the coloring intensity are improved in a manner combining physical adsorption and chemical bonds. A dye reagent can be mutually dissolved with various cosolvents and is high in forming speed, and rapid forming of full-color sandstone for 3DP can be realized. The process is simple, the forming cycle of the product is short, the production efficiency is high, the designability is high, and the full-color sandstone dye and the forming method are suitable for realization of large-scale and industrialized 3DP technology.

Description

technical field [0001] The present invention relates to the field of 3DP printing, more specifically, to a full-color sandstone dye for 3DP printing and a molding method of its products. Background technique [0002] 3DP (Three Dimensional Printing) printing technology is also called rapid prototyping technology. This method has the advantages of fast forming speed, low cost and high utilization of equipment space. 3DP printing technology completes the transformation of the model from conceptual design to three-dimensional by redefining the traditional planar drawing design mode, realizes the purpose of using the design scheme for precision processing and manufacturing, and transforming the model file into a part or product with a specific size , and greatly shorten the product development cycle. [0003] With people's pursuit of green environmental protection and advocating nature, sandstone cultural bricks with sandstone as aggregate have been highly sought after in many ...
