preparation example Construction

[0012] The invention provides a method for preparing an attapulgite soil-based 3D printer support, comprising:

[0013] 1) Calcining attapulgite, shells and black loam, then placing the calcined product in hydrochloric acid solution for acidification, filtering to take the filter cake, and then placing the filter cake under X-rays for activation treatment to obtain the activated product ;

[0014] 2) Epoxy resin, phenol furan resin, methyl cellulose, basic magnesium sulfate whisker, magnesium oxide, valine, glass fiber, pitch, sodium azulene sulfonate, potassium aluminum sulfate, thienopyrimidine, swelling Graphite, ozokerite, sodium humate and cocoic acid monoethanolamide were mixed, melted, and cooled to make an attapulgite-based 3D printer support.

[0015] In step 1) of the present invention, the specific conditions of calcination can be selected in a wide range, but in order to make the 3D printer support made have more excellent mechanical stability, preferably, in step...

Embodiment 1

[0026] 1) Mix attapulgite, shell and black loam in a weight ratio of 100:21:4.5 and calcinate at 515°C for 6.5h, then place the calcined product at 50°C in a hydrochloric acid solution with a concentration of 28% by weight (relative to In the described attapulgite of 100 parts by weight, the consumption of hydrochloric acid solution is 100 parts by weight), carry out acidification treatment 1.5h, filter and get filter cake, then filter cake is placed in X-ray (wavelength is 30 Angstroms) and temperature is Activation treatment was carried out for 50 minutes at 25°C to obtain the activated product;

[0027] 2) Bisphenol A type epoxy resin (weight average molecular weight is 7000), phenol furan resin (weight average molecular weight is 5000), activator, methyl cellulose, basic magnesium sulfate whisker, magnesium oxide, valine , glass fiber, asphalt, sodium azulene sulfonate, potassium aluminum sulfate, thienopyrimidine, expandable graphite, ozokerite, sodium humate and cocoic a...

Embodiment 2

[0029] 1) Mix attapulgite, shell and black loam in a weight ratio of 100:20:3.5 and calcinate at 500°C for 6h, then place the calcined product at 45°C in a hydrochloric acid solution with a concentration of 25% by weight (relative to 100 parts by weight of the attapulgite, the amount of hydrochloric acid solution is 80 parts by weight), acidified for 1h, filtered to get the filter cake, then the filter cake is placed in X-ray (wavelength is 20 Angstroms) and the temperature is 15 ° C Activation treatment was carried out for 45min under certain conditions to obtain an activated product;

Abstract

The invention discloses an attapulgite based 3D printer bracket and a preparation method thereof. The preparation method comprises the following steps: (1) calcining attapulgite, shell and heilu soil, then putting a calcined object into a hydrochloric acid solution for acidizing, filtering and taking a filter cake, and then putting the filter cake to be under X-rays for activating treatment, thus obtaining an activated object; (2) mixing epoxy resin, phenol-furfural resin, methylcellulose, basic magnesium sulfate whisker, magnesium oxide, valine, glass fibre, pitch, sodium gualenate, aluminium potassium sulfate, thienopyridine, expansible graphite, ozocerite, sodium humate and coconut oil mono ethanol amide, fusing and cooling, thus obtaining the attapulgite based 3D printer bracket. The 3D printer bracket prepared by the method has excellent mechanical stability for improving the performance of a 3D printer.

Description

technical field [0001] The invention relates to a 3D printer support, in particular to an attapulgite soil-based 3D printer support and a preparation method thereof. Background technique [0002] One end of the 3D printer support is connected to the 3D printer body, and the other end is connected to the 3D printer nozzle, and the only function is to support the 3D printer nozzle. In the 3D printing process, the stability of the nozzle of the 3D printer is extremely important, because the stability of the nozzle directly determines the specific location of the accumulation of raw materials ejected from the nozzle, which in turn affects the shape and quality of the printed object. [0003] At present, 3D printer supports are generally made of polymer materials, which are corrosion-resistant, light and cheap, but polymer materials are prone to deformation after long-term use, thereby reducing the 3D printer performance. Contents of the invention [0004] The purpose of the ...
