Abstract

The invention discloses a method for preparing a recycled regenerated plastic for printing. The recycled and regenerated plastic for 3D printing, which is disclosed by the invention, comprises 60-70 parts of a recycled plastic, 5-20 parts of glass fibers, 3-10 parts of graphenoid, 1-10 parts of a toughening agent, 2-3 parts of a dispersant, 1-15 parts of biochar, 1-5 parts of a compatibilizer, 0.1-2 parts of a chain extender, 0.5-1 part of a lubricant, 0.1-5 parts of a foaming agent and 1-8 parts of other additives. In addition, recycled and regenerated plastic may also comprise 10-60 parts ofEVA (ethylene vinyl acetate), and the content of VA (vinyl acetate) of EVA is 20-55%. The graphenoid is one of silicene, germanene and molybdenum disulfide surface activity treatment. The chain extender is one or more of pyromellitic dianhydride, dicumyl peroxide and an acrylonitrile-butadiene-styrene copolymer. The recycled and regenerated plastic is one or more of ABS (acrylonitrile butadiene styrene), polypropylene and PET (polyethylene terephthalate).

Description

technical field

[0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a recycled plastic used for 3D printing and a preparation method thereof.

[0002] technical background

[0003] Polypropylene (PP) is a semi-crystalline thermoplastic resin, usually a translucent colorless solid, odorless and non-toxic. Due to its good mechanical properties, good thermal stability, excellent molding performance and relatively low price, it is widely used in the fields of automobiles, home appliances, and electronics. However, unmodified PP has disadvantages such as low tensile strength, poor impact resistance, and flammability, which limit its further application.

[0004] In order to solve this problem, the industry usually adopts the method of blending polypropylene with other types of resins and additives to improve the performance of the material. Glass fiber reinforced composite material is a composite material made of polym...
