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, the products produced by the 3D plastic line consumables factory are only ordinary colored products, which are limited to general-purpose products and cannot be applied to night or dark occasions. The color of the product is monotonous

Embodiment 1

[0018] 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.

[0019] The preparation method of this PBS composite material is as follows:

[0020] (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

[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 1:8. 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

[0028] 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 a photochromic PBS composite wire rod for 3D printing. The photochromic PBS composite wire rod for 3D printing is composed of the following raw materials (by weight): 75-85 parts of PBS, 0-2 parts of PHA, 0-5 parts of a compatilizer, 0.1-0.5 part of a chain extender, 0.1-0.5 part of a cross-linking agent, 0.1-2 parts of a nucleating agent, 0.2-1 part of an antioxidant, 0.2-2 parts of a lubricant, 0.5-2 parts of multiwalled carbon nanotube / ZnO composite powder, and 0.5-1 part of multiwalled carbon nanotube / photochromic powder. According to the invention, multiwalled carbon nanotube is treated in advance, and photochromic powder is adsorbed on the multiwalled carbon nanotube to form composite powder; and then, a scientific ratio is obtained by multiple tests, and the composite powder is combined with PBS and PHA so as to prepare the composite wire rod for a 3D printer. In comparison with a traditional wire rod, the wire rod of the invention can show different colors under irradiation of different light intensities. In addition, the color is mellow and full, photochromic uniformity is good. The wire rod of the invention also has low printing temperature and good tensile strength and flexibility. Meanwhile, the wire rod has low shrinkage so as to prevent the problem of warping after printing. The wire rod of the invention is applicable to multiple 3D moulding technologies, and has a 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 photochromic 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...
