Embodiment 1

[0029] A kind of preparation method steps of high temperature black ceramic pigment for laser 3D printing is as follows:

[0030] (1) Take 180gCrCl 3 ·6H 2 O, 250gFeCl 3 ·6H 2 O, 250g CoSO 4 ·7H 2 O, 70g MnSO 4 ·H 2 O, 35gNi(NO) 2 ·6H 2 Dissolve O in 5000ml of water to form A, 350g of NaOH dissolved in 5000ml of water to form B, 0.4g of polyethylene glycol-2000 dissolved in 2000ml of water to form C, drop A and B into C to keep the pH at 8, and obtain D solution, stir After 1 hour, wash D with water until no ions are washed out, dry at 120°C and pulverize through 200 meshes to obtain E, mix 3wt% NaCl and E into a crucible, calcinate at 1100°C for 60 minutes, grind with water for 10 minutes, rinse and dry , broken into F, reserved for step 2 modification treatment, its scanning electron microscope picture is as follows figure 2 , the particle crystallization is complete and the size is uniform, which is beneficial to the subsequent processing steps.

Embodiment 2

[0034] Take 200g CrCl 3 ·6H 2 O, 230g FeCl 3 ·6H 2 O, 260g CoSO 4 ·7H 2 O, 75g MnSO 4 ·H 2 O, 35gNi(NO) 2 ·6H 2 O dissolved in 5000ml water is A 1 Solution, 280gNaOH dissolved in 5000ml water is B 1 , 0.5g polyethylene glycol-2000 dissolved in 2000ml water is C 1 , put A 1 and B 1 Co-dropped in C 1 Keep the pH at 8 and record it as D 1 , then D 1 Transfer to a hydrothermal kettle at a constant temperature of 200°C for 18 hours, rinse until ion-free, dry and break, record as E 1 ; then E 1 Calcined at 900°C, milled with water for 5 minutes, dried and crushed, recorded as F 1 , reserved for step 2 modification treatment, its scanning electron microscope picture is as follows image 3 As shown, the particles are more rounded than F, the particles are more uniform, and the thermal stability is better. The subsequent steps are as described in Example 1, and the resulting product is denoted as K 1 ,Such as Figure 5 shown.

Embodiment 3

[0036] The difference between this embodiment and embodiment 1 is that A liquid is 200gCrCl 3 ·6H 2 O, 250gFeCl 3 ·6H 2 O,280gCoSO 4 ·7H 2 O, 80g MnSO 4 ·H 2 O, 35g Ni(NO) 2 ·6H 2 O is dissolved in 5000ml of water, and B liquid is 290g. The color tone of the F color material obtained in this embodiment is black and bluish, and the finally prepared laser pigment K is also blue and black when applied to laser decals.

Abstract

The invention discloses a preparation method for a high-temperature black ceramic pigment used for laser 3D printing. The preparation method comprises liquid-phase synthesis of a high-temperature black ceramic pigment and preparation of the high-temperature black ceramic pigment used for laser 3D printing through polymerization modification. The method comprises the following concrete steps: weighing a metal salt mixture of Cr<3+>, Fe<3+>, Co<2+>, Mn<2+> and Ni<2+> in a mol ratio of (0.06-0.08): (0.1-0.12): (0.04-0.06): (0.04-0.06): (0.01-0.02) and a proper amount of alkali and preparing the high-temperature black ceramic pigment with uniform particles through solution-coprecipitation and hydrothermal process; modifying the surface of the pigment by using a silane coupling agent and adding white carbon black at the same time; and carrying out polymerization, cladding and modification by using mixed monomer styrene / acrylic acid so as to eventually obtain the pigment for laser 3D printing. The high-temperature black ceramic pigment used for laser 3D printing prepared in the invention can meet usage requirements of a ceramic laser 3D printer.

Description

technical field [0001] The invention relates to a black ceramic pigment, in particular to a method for preparing a high-temperature black ceramic pigment for laser 3D printing. Background technique [0002] Since around 2009, domestic architectural ceramic decorative pigments have begun to use ceramic inkjet pigments imported from abroad on a large scale. Due to their incomparable advantages in personalization, small batches, and fineness compared with screen printing and roller printing, so After the ban on foreign technology was lifted and introduced into our country, it quickly occupied a large market share. After several years of digestion and absorption by people in the domestic industry, at present, domestic enterprises have been able to prepare various commonly used ceramic inkjet printing inks. Of course, the entire ceramic inkjet industry still has some technical barriers to be overcome by the Chinese. For example, the nozzles used in inkjet machines are still cont...
