Problems solved by technology

At present, it can be applied to catering utensils, daily necessities, agricultural materials, biomedical polymer materials, food and drug packaging materials, etc., but there is a problem of heat shrinkage when pure PBS is directly applied to 3D printing, and its toughness and tensile strength are also low. to be further improved
At present, there are few reports on 3D printing materials with negative ion function

Embodiment 1

[0016] A PBS composite wire for 3D printing, which consists of the following raw materials in parts by weight: 80 parts of PBS, 2 parts of PHA, 2 parts of compatibilizer, 0.2 part of chain extender, 0.3 part of crosslinking agent, 0.5 part of nucleating agent, anti- 1 part of oxygen agent, 1 part of lubricant, 1.2 parts of multi-walled carbon nanotubes / ZnO composite powder, described multi-walled carbon nanotubes / ZnO composite powder is made of multi-walled carbon nanotubes and flower-shaped nano ZnO by weight ratio 1:2 composition.

[0017] The preparation method of this PBS composite material is as follows:

[0018] (1) Preparation of flower-shaped nano-ZnO: Weigh 0.76783g of zinc acetate dihydrate and 1.96g of sodium hydroxide into beakers A and B respectively and dissolve them with 10ml deionized water to form a transparent solution. In a cold water bath (5°C) and stirred at a constant speed, drop the sodium hydroxide solution in the beaker B into the beaker A slowly and ...

Embodiment 2

[0024] Based on Example 1, the only difference is that the multi-walled carbon nanotube / ZnO composite powder is composed of multi-walled carbon nanotubes and flower-shaped nano-ZnO in a weight ratio of 1:8. The prepared PBS composite wire was subjected to 3D printing test, the printing temperature was 145°C, the printing process was smooth, the surface of the printed product was smooth and well-proportioned, the appearance was beautiful, the size was stable and no warping.

Embodiment 3

[0026] Based on Example 1, the only difference is that the multi-walled carbon nanotube / ZnO composite powder is composed of multi-walled carbon nanotubes and flower-shaped nano-ZnO in a weight ratio of 1:15. The prepared PBS composite wire was subjected to 3D printing test, the printing temperature was 145°C, the printing process was smooth, the surface of the printed product was smooth and well-proportioned, the appearance was beautiful, the size was stable and no warping.

Abstract

The invention discloses an anion PBS (poly butylenes succinate) composite wire for 3D (three-dimensional) printing, which is prepared from the following raw materials in parts by weight: 75 to 85 parts of PBS, 0 to 2 parts of PHA (polyhydroxyalkanoate), 0 to 5 parts of compatilizer, 0.1 to 0.5 part of chain extender, 0.1 to 0.5 part of cross-linking agent, 0.1 to 2 parts of nucleating agent, 0.2 to 1 part of antioxidant, 0.2 to 2 parts of lubricant, 0.5 to 2 parts of multiwalled carbon nanotube / ZnO composite powder and 1 to 4 parts of anion powder. According to the anion PBS composite wire for 3D printing, the anion powder can release anions, anion concentration can be improved, air quality can be improved, harmful gas can be reduced, and the anion PBS composite wire for 3D printing has wide application prospect in the field of 3D printing.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a negative ion PBS composite wire for 3D printing. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is actually an emerging technology in the field of rapid prototyping. A technique for constructing objects in a manner. The basic principle is additive manufacturing, the technique of adding material layer by layer to generate a three-dimensional solid. At present, 3D printing technology is mainly used in product prototyping, mold manufacturing, art creation, jewelry making and other fields, replacing these traditional fine processing techniques. In addition, 3D printing technology is gradually applied in fields such as medicine, bioengineering, architecture, clothing, aviation, etc., opening up a broad space for innovation. [0003] Polybutylene succinate (PBS), also known as polybutylene succinate or polybutylene succinat...
