preparation example Construction

[0012] The invention provides a method for preparing a calamus-based modified base material for a 3D printer, comprising:

[0013] 1) The calamus is cleaned and crushed, then the calamus powder is mixed with the bamboo charcoal powder and soaked in the mixed solution of hexamethylenetetramine and hydrochloric acid, and then the filter cake is filtered to obtain a modified composition;

[0014] 2) Mix polyvinyl fluoride, modified composition, polyundecylamide, polyazalic anhydride, borax, lanolin magnesium soap, rosin, steel fiber, gypsum powder, dioctyl adipate, and zinc borate, then melt , cooling and granulation to make 3D printer base material.

[0015] In the step 1) of the present invention, the specific conditions for finishing can be selected in a wide range, but in order to make the prepared 3D printer base material have more excellent mechanical properties and oxidation resistance, preferably, in step 1) , at least meet the following conditions: finishing temperature...

Embodiment 1

[0027] 1) The calamus was killed at 155°C for 30 minutes, crushed to a particle size of 0.2mm, and then the calamus powder, bamboo charcoal powder (0.3mm particle size), hexamethylenetetramine, hydrochloric acid (24% by mass fraction) According to the weight ratio of 100:30:48:20-28, mix and soak at 75°C for 2.5 hours, then filter and take the filter cake to obtain the modified composition;

[0028] 2) Polyvinyl fluoride (weight-average molecular weight is 4500), modified composition (weight-average molecular weight is 5000), polyundecamide (weight-average molecular weight is 10000), polyazalic anhydride, borax, lanolin magnesium soap, Rosin, steel fiber (3mm in length, 0.2mm in radial section diameter), gypsum powder, dioctyl adipate and zinc borate according to 100:17:40:17:12:25:20:20:10 : 25:12 weight ratio mixed, then melted at 185°C for 35min, cooled at 25°C and granulated to prepare 3D printer base material A1.

Embodiment 2

[0030] 1) The calamus was killed at 145°C for 25 minutes, crushed to a particle size of 0.1mm, and then the calamus powder, bamboo charcoal powder (0.2mm particle size), hexamethylenetetramine, hydrochloric acid (20% by mass fraction) According to the weight ratio of 100:27:45:120, mix and soak at 70°C for 2 hours, then filter and take the filter cake to obtain the modified composition;

[0031] 2) Polyvinyl fluoride (weight-average molecular weight is 3500), modified composition (weight-average molecular weight is 4000), polyundecamide (weight-average molecular weight is 8000), polyazalic anhydride, borax, lanolin magnesium soap, Rosin, steel fiber (1mm in length, 0.1mm in radial section diameter), gypsum powder, dioctyl adipate and zinc borate according to 100:14:37:14:9:22:14:14:7 : 20:7 weight ratio mixed, then melted at 180°C for 30min, cooled at 15°C and granulated to prepare 3D printer base material A2.

Abstract

The present invention discloses a 3D printer base material based on acorus calamus l modification, and a preparation method thereof. The preparation method comprises: 1) deactivating acorus calamus l, grinding, mixing the acorus calamus l powder and bamboo charcoal powder, soaking the obtained mixture in a hexamethylenetetramine and hydrochloric acid mixing solution, and filtering to obtain filter cake so as to prepare a modified composition; and mixing polyvinyl fluoride, the modified composition, poly undecanoic amide, polyazelaic acid anhydride, borax, lanolin magnesium soap, rosin, steel fibers, gypsum powder, dioctyl adipate and zinc borate, melting, cooling, and granulating to prepare the 3D printer base material. According to the present invention, the 3D printer base material prepared through the method has excellent impact resistance and excellent aging resistance.

Description

technical field [0001] The invention relates to a 3D printer base material, in particular to a calamus-based modified 3D printer base material and a preparation method thereof. Background technique [0002] The 3D printer base is one of the more important components in the 3D printer. The 3D printer base only needs to play the role of support and load-bearing. In actual production, the requirement for the 3D printer base is to have excellent stability and mechanical properties. [0003] At present, the 3D printer base can be divided into metal base and polymer base according to the material. Although the metal base has strong mechanical properties, the cost of the metal base is high. Although the cost of the polymer base is relatively cheap, the mechanical properties and anti-aging aspects of the polymer base are poor, which greatly affects the application of the polymer base in 3D printers. Contents of the invention [0004] The object of the present invention is to pr...
