Problems solved by technology

The building material proposed by the invention has excellent sound insulation performance and good mechanical properties, but the material prepared by the invention is only suitable for building materials
[0006] With the rapid development of 3D printing technology, 3D printing materials, as an important part of 3D printing technology, have received more and more attention. At present, there are very few 3D printing materials with sound insulation function, which greatly limits the selection of 3D printing materials. Therefore, it is of great significance to develop a 3D printing material with sound insulation function suitable for 3D printing to promote the development of 3D printing and enrich 3D printing materials.

Abstract

The invention discloses a sound insulating material for 3D (three-dimensional) printing. The sound insulating material mainly comprises materials as follows: 40-50 parts of polyvinyl chloride by weight, 35-45 parts of porous spherical calcium carbonate by weight, 10-20 parts of pine wood powder by weight, 2.0-4.0 parts of talc by weight, 0.8-1.6 parts of a silane coupling agent by weight and 0.2-0.4 parts of stearic acid by weight. By the aid of the characteristics of good heat insulating performance, good liquidity and excellent mechanical property of the porous spherical calcium carbonate as well as the characteristics of good mechanical property, low price and abrasion resistance of the pine wood powder, the prepared sound insulating material for 3D printing has the sound insulating function, the good liquidity and the excellent mechanical property and is applicable to the 3D printing technology. The invention further discloses a preparation method of the sound insulating material for 3D printing. The preparation method adopts the simple preparation technology, is low in cost, safe and environment-friendly, and has the market application prospect.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a sound insulation material for 3D printing. Background technique [0002] 3D printing technology is a new type of printing technology. As a kind of rapid prototyping technology, 3D printing technology can be traced back to the patent on 3D printing declared by Scans E.M. and Cima M.J. of the Massachusetts Institute of Technology in 1991. . Compared with two-dimensional printing, this technology differs in that the document or photo printed by two-dimensional printing is a flat two-dimensional pattern, while what is printed by 3D printing is a three-dimensional object. 3D printing and two-dimensional printing have similarities. For example, two-dimensional printing is to spray ink and other materials on the printing material, generally the thickness is not high, a few microns. However, if the substrate is printed not only once, but multiple times, the thickness of the "...
